The Chevrolet Suburban is a full-size, extended-length sport utility vehicle from Chevrolet. It is the longest continuous use automobile nameplate in production, starting in 1935 for the 1935 U.S. model year, and has traditionally been one of General Motors' most profitable vehicles.^[1] The Suburban has been produced under the Chevrolet, Holden, and GMC marques until the GMC version was rebranded as the GMC Yukon XL. For most of its recent history, the Suburban has been a station wagon-bodied version of the Chevrolet pickup truck, including the Chevrolet C/K and Silverado series of truck-based vehicles. Cadillac offers a version called the Escalade ESV.

The Suburban is sold in the United States (including the insular territories), Canada, Mexico, Chile, and the Middle East (except Israel) as a Left-hand drive vehicle, while the Yukon XL is sold only in North America (United States and Canada) and The Middle East territories (except Israel).

History

Several automotive companies in the United States used the "Suburban" designation to indicate a windowed, station wagon type body on a commercial frame including DeSoto, Dodge, Plymouth, Studebaker, Nash, Chevrolet, and GMC. The (Westchester) Suburban name was in fact a trademark of U.S. Body and Forging Co. of Tell City, Indiana, which built wooden station wagon bodies for all of these automobile and light truck chassis and more.

Chevrolet began production of its all-steel "carryall-suburban" in 1935. GMC brought out its version in 1937. These vehicles were also known as the "Suburban Carryall" until GM cut the name to simply "Suburban". GMC's equivalent to the Chevrolet model was originally named "Suburban" as well, until re-branding it to "Yukon XL" for the 2000 model year.

With the end of production of the Dodge Town Wagon in 1966 and the Plymouth Suburban station wagon in 1978, only General Motors continued to manufacture a vehicle branded as a "Suburban", and GM was awarded an exclusive trademark on the name in 1988. The Chevrolet Suburban is one of the largest SUVs on the market today. It has outlasted competitive vehicles such as the International Harvester Travelall, Jeep Wagoneer, and the Ford Excursion. The latest competitor is the extended Ford Expedition EL, which replaced the Excursion.

The Suburban of today is a full-size SUV with three rows of seating, a full pickup truck frame, and V8 engine. It is one of the few station wagons available with all bench rows. The Suburban is the same height and width as the Chevrolet Tahoe, although the Suburban is 20 inches (510 mm) longer. The extra length provides a full-sized cargo area behind the 9 passenger seating area. From 1973 to 2013 it had been available in half-ton and 3/4-ton versions, the latter discontinued after the 2013 model year, but was revived in 2015 as a fleet-exclusive vehicle for the 2016 model year.

In recent years, the Suburban has been used as a police car, fire chief's vehicle, or EMS fly-car. Suburbans are also used as limousines. The United States Secret Service uses black Suburbans, and operates fully armored versions for the President of the United States when he attends less formal engagements.

In the late 1990s, GM also introduced a RHD version of the Suburban, badged as a Holden, for the Australian market. Sales were low and GM withdrew the model in 2000 from Holden's lineup.

There has been twelve generations of Chevrolet Suburbans since its 1935 debut, the most recent (starting with the 2015 model year) entering showrooms in February 2014. On March 25, 2015, Chevrolet celebrated the Suburban's 80th anniversary with the Arlington Assembly plant unveiling the 10th million vehicle built at the facility since its 1954 opening, a black 2015 Suburban LTZ.^[2] This marked the second time in the Suburban's history that it has achieved this honor, as the eleventh generation Suburban from the 2011 model year was also the ninth million vehicle built there.^[3]

On July 28, 2014, GM revealed details that a thirteenth generation Suburban/Yukon XL would be introduced in 2019. This would take place after the next generation GM trucks are introduced in 2018, which was moved up by nine months (it had been planned for a 2019 launch) in an effort to narrow the competition with Ford's truck and SUV lineup. Eventually the twelfth-generation Chevy Suburban will get Ford's 10-speed 10R80 automatic transmission^[4] as part of a joint venture between GM and Ford. In-return, General Motors will let Ford use its upcoming GM 9-speed transmission for front-wheel drive vehicles.^[5]

Prior to this first generation Suburban, Chevrolet offered a station wagon body, built on the 1/2 ton truck frame. This model was specifically built for National Guard units and Civilian Conservation Corps units. Much of the body was constructed from wood, and could seat up to eight occupants.

The actual first generation model was offered by Chevrolet as a "Carryall Suburban". It shared the front sheetmetal and frames of the 1/2 ton pickup models of the same year, but featured all-metal wagon bodies differing very little in shape from contemporary "woodie" wagons. Seating for up to eight occupants was available, with three in front row, two in the middle row, and three in the rear row. Either the side-hinged rear panel doors or a rear tailgate/lift window could be selected for cargo area access.

Suburbans were built in model years 1941, 1942, and 1946. It was produced during the war as a military transport vehicle.^[6] Seating for up to eight occupants was available. Models with rear panel doors were designated "3106," while those with tailgates were designated "3116." The Chevrolet versions were equipped a 216-cubic-inch 6-cylinder engine. The GMC version was equipped with a 228-cubic-inch 6-cylinder engine. It shared much of its mechanicals with the AK Series trucks.

This model generation was based on the Chevrolet Advance Design series of pickups.

Beginning in 1953, the Hydra-Matic 4-speed automatic transmission was available in GMC models and in the 1954 model year Chevrolet Suburbans. Models with rear panel doors were designated "3106," while those with tailgates were designated "3116." In 1952, the Suburban came with either a tail gate or panel doors.^[6] The front bench seat was split, with two seats on the drivers side and a single seat on the passenger side, which slid forward for access to the rear two rows of seats. The second row was a "2/3" seat, requiring occupants to move past the front passenger seat, as well as the second row seats to access the third row.

This was the last series to feature "Canopy express" models.

The design of the 1949 Suburban would go on to inspire the design of the Chevrolet HHR over half a century later.

Updated engineering and styling on Chevrolet trucks was not introduced until March 25, 1955, in the middle of the model year that GM called the Chevrolet Task Force/GMC Blue Chip series. All Chevrolet and GMC truck models received new styling that included a flatter hood, front fenders flush with the body, and a trapezoid grill.^[6] The trucks' V-shaped speedometer was shared with passenger car models.^[13]

Engines included I-6 and the small block V8s. Chevrolet used its 265 V8 engine, later evolving it to a 283-cubic-inch version. GMC based their V8 on a Pontiac design. Standard Suburban model numbers continued from the previous series, but the introduction of four-wheel-drive models in 1957 added the numbers "3156" for 4WD Suburbans with panel doors, and "3166" for 4WD Suburbans with tailgates.^[14]

The "Suburban" name was also used on GM's fancy 2-door GMC 100 series pickup trucks from 1955–1959, called the Suburban Pickup, which was identical to the Chevrolet Cameo Carrier, but it was dropped at the same time as Chevy's Cameo in March 1958 when GM released the new all-steel "Fleetside" bed option replacing the Cameo / Suburban Pickup fiberglass bedsides. The Suburban name was never used again on a 1/2 ton pickup after the discontinuance of the Suburban Pickup. Although not documented due to a fire which destroyed the records, the production of Suburban Pickups is understood to be 300 or fewer each model year it was offered from 1955-1958.

The styling of the 1960 – 1961 model year took cues from the late 1950s Chevrolet cars and had large oval ports above the grille. Front independent suspension was new for 1960.^[16] The cab featured a "wrap around" windshield. Both tailgate and panel doors rear openings were available. From 1962 onwards, the hood styling was more conservative, with hoods that eliminated the large ports. In 1964, the front glass area was updated to a flatter windshield, and larger door glass. 1,150 lb (520 kg) of cargo could be carried in the back.^[17]

This model series introduced a factory-equipped 4WD ("K") option for the first time. The 2WD "C" models introduced a torsion bar-based independent front suspension and trailing arm and coil spring rear. But by 1963, returned to a more conventional coil-spring approach.

Engines included both I-6 and small-block V8s. A 305 cu in (5.0 L) GMC V6 engine was also available on GMC models. This 305 was actually from GMCs medium-duty truck line. It featured high torque, but was also notable for poor fuel economy. Transmissions were a 3-speed and 4-speed manual, the automatic Powerglide and the dual-range Hydramatic in the GMC models.

A 15-passenger conversion was done by Stageway of Fort Smith, Ark. These modified Suburbans had three doors on the right, a 171 in (4,343 mm) wheelbase, were 273 in (6,934 mm) long, and weighed 6,300 lb (2,858 kg).^[6]

One ton (C-30), 10-foot (3 m) panel truck models were no longer available after 1966.

Chevrolet Suburban C10 badge

Chevrolet Suburban C10

The 6th generation Suburbans featured a single driver-side door and two passenger-side doors, and were available in both 2WD and 4WD models.

Engines offered over the six model years included the 250 and 292 CI inline 6, 283, 307, 327, and 350 CI small block V-8, and 396/402 CI big block V-8. For the first time, a three-quarter ton version was available.

This series would also be the last to offer C-10 & C-20 panel truck models for commercial purposes, with 1970 as the last year.

1971 models featured disc brakes on the front wheels,^[21] and 1972 was the last year for coil-spring rear suspension on 2WD models. 1972 also introduced a smaller housing for the rear seat air conditioning (a unit that ran the full length of the roof had been available since 1967). The Comfort-Tilt steering wheel became optional in 1971.^[22]

Chevrolet Veraneio (Brazil)

1971–78 Chevrolet Veraneio

In 1964, Chevrolet in Brazil introduced a 5-door version of the Suburban called C-1416 (known as Veraneio from 1969 onwards). It was based on the contemporary Brazilian Chevrolet C-14. Like the C-14, the C-1416/Veraneio used the instrument cluster from the US C/K series although the exterior sheet metal layout is exclusive to Brazil. It was initially powered with a Chevrolet 4.2 L inline six based on the pre-1962 "Stovebolt" engines. Later it used the 250-cid 4.1 L engine from Chevrolet's Brazilian mid-size sedan – the Opala. The original version of the Veraneio was kept in production, with another grille and interior, until 1988 (model year 1989), but it was eventually replaced with an updated version based on the Série 20 family.^[23]

In 1997 GM introduced in Brazil the North American pickups for the local market, replacing the "C Series". The Brazilian version of the Suburban was also converted to the current generation at the time and lasted until 2001, was called the Grand Blazer, a successor to the Veraneio. The 4.1 L inline six engine with 138 hp (103 kW) was offered on both models with option for a MWM 4.2 L turbodiesel unit with 168 hp (125 kW).

On September 15, 2015, Autoweek ranked the Veraneio fourth among the Chevrolet station wagons that America never got. It also cited the vehicle's design as "baroque" and summed it up as "It's a 1960s Brazilian crossover." Autoweek notes that The Veraneio can be imported to the United States, depending on the condition of the vehicle.^[24]

With the third generation Rounded-Line C/R & K/V models, the Suburban became a four-door vehicle.^[25] The Rounded-Line 1970s body style remained largely unchanged for 19 model years – making this series the longest Suburban generation in production. Both 2WD (C/R) and 4WD models (K/V), were offered, as well as half ton and three-quarter ton models ("1500" and "2500" on the Chevrolet models as well as on the GMC models). The one-ton model designation was the C/R or K/V 3500 for GMC and Chevrolet.

Suburbans for model year 1973^[26] now had two doors on each side (the previous generation had just one door on the driver's side), front-and-rear air conditioning, a baggage rack, a heater under the third seat and step-plates for easier access.^[27] A new Eaton Automatic Differential Lock was introduced as an option extra for the rear differential.

The base engine was the small-block 305-cubic-inch V8. A 350-cubic-inch V8 and a 400-cubic-inch V8 were optional. The 454-cubic-inch big-block V8 was now available for the first time. The 6.2 L (379 cu in) 130 hp (97 kW) Detroit Diesel V8 engine was also available from 1982-onwards.^[28] The Diesel later became the engine of choice for Suburbans exported to Europe from USA.

Three-speed Turbo Hydra-Matic 350 automatic transmissions were available for only small block engines. The Turbo Hydra-Matic 400 was used for small and big block and 6.2 diesel engines. The four-speed Turbo Hydra-Matic 700R4 was introduced in 1981 and was available with the small block and the 6.2-liter diesel. Towing packages, with axle gear reduction and cooling additions for heavy loads, were optional.

Trim options included base (Scottsdale) level and upgraded Silverado versions. An optional 3rd row bench seat allowed for nine-passenger configurations. A rear heating system was optional.

For model year 1981, automatic locking front hubs were added for shift-on-the-move four-wheel drive models, and the NP208 transfer case replaced the NP205 in most models.^[29]

For 1984, asbestos was removed from rear brakes. For 1985, a new grille was used.^[30] A total of 64,670 Suburbans were made in 1985.^[30]

For model year 1987, the method of fuel delivery for the engines was switched from carburetors to electronic fuel injection. The system that GM chose was called throttle body injection, or TBI. Suburban gained rear-wheel anti-lock braking system (ABS) for the 1990 model year. A heavy-duty four-speed automatic transmission, the 4L80-E was added for 1991. Also for 1989, the grille was redesigned to accommodate a quad side-by-side headlight setup and larger marker lights/turn signals than the previous dual filament single headlight setup, which was styled concurrently with the GMT400 light duty trucks. Economy models (usually for fleet usage) were available with only two headlights (again, based on the base model C/K series).

GM temporarily changed the usual "C/K" designation to "R" and "V" for the 1987 through 1991 model years. This was done to avoid confusion with the GMT400-based Chevrolet C/K pickup trucks, which were introduced in 1988, during the overlap period.

The GMT400-based Suburbans were introduced in the 1992 model year. The similar pickup truck models had switched to the newer platforms in the 1988 model year. Both 2WD and 4WD models, designated "C" and "K", were offered, as well as half ton and three-quarter ton ("1500" and "2500") models.

The base engine for all variants was the small-block 5.70liter (350 cu in) V8. The big-block 7.4 L (454 cu in) V8 was optional for the 2500 series. The optional 6.5 L Turbo diesel was available on all models – though rare on the 1500 series. The 6.5 L Turbo diesel used in the Tahoe was detuned to 380 lb·ft (520 N·m) torque due to the limitation of the 8.5-inch (220 mm) axle capacity. 1500 Suburbans with the 6.5 L Turbo diesel used the 14 bolt axle from the 2500 series. Ground clearance was 6.9 inches, the approach angle was 18 degrees for the K-1500 (28 degrees for the K-2500) and the break over angle was 18 degrees.^[31]

Transmissions included the 4L60 four-speed automatic in the 1500 series, and the heavier duty 4L80 four-speed automatic in the 2500 series. The manual transmission option from the previous generation was dropped.

The GMT400 series introduced independent front suspension. The 2WD models used coil springs and 4WD models used torsion bars in the front suspension. All models used a live axle and leaf springs in the rear.

0–60 mph time for a 1995 Suburban was 9.3 seconds. Top speed of a 1995 Suburban is governed on the engine for economy. A maximum of 98 mph (158 km/h) can be obtained.^[31] City fuel economy was 13 mpg_-US (18 L/100 km)^[31] and highway was 15 mpg_-US (16 L/100 km).^[31] The turning circle was 47.8 ft (14.6 m).^[31] In 1996, fuel economy had improved to 17 mpg_-US (14 L/100 km) highway.^[32]

Trim options included a base-level version, the LS, and the LT. Interior seating arrangements allowed for either bucket or bench seating in the first row, and optional third row bench. The vehicle could be configured from two- to nine-passenger seating.

Beginning in 1994, GM began making numerous annual changes to the Suburban, including:

• Revised front clip and center stop lamp (1994)
• Revised interior including a driver-side air bag, revised side mirrors (1995)
• Revised Vortec L31 (350 cu. in.) and Vortec 7400 (454 cu. in) engines with increased power and fuel efficiency, electronic 4WD shifting, daytime running lights, illuminated entry, and some new interior features (1996)
• Revised transmissions, improved steering system and added passenger-side air bag (1997)
• Onstar, PassLock security system and full-time AutoTrac 4WD option added, next generation "depowered" air bags, revised steering wheel, transmissions revised again (1998)
• No major changes upon introduction of redesigned 2000 models (1999)

In 1998, Holden introduced a right-hand-drive version of Suburban for the Australian and New Zealand markets with either petrol or diesel motors. A modified dashboard from 1995 to 2005 RHD Chevrolet Blazer was used. Sealed beam headlights (from the 1988–93 C/K series) were used in place of the one-piece composite headlights sold in the USA and Canada. The models were withdrawn as a Holden brand because of low quality and sales.

In Australia and New Zealand, Holden imported the right-hand drive Chevrolet Suburban built by GM in Silao, Mexico between February 1998 and January 2001.^[33] The Suburban was first previewed in October 1997 at the Sydney Motor Show.^[34] In total, 746 were sold (460 petrol and 286 diesel), an average of less than 250 units per year.^[35] After 2001, subsequent models reverted to the original Chevrolet brand, which had also been used before 1998. Over the model's lifetime there were three trim levels: a base model, the LS and the LT. Not to be confused with the trim variants is the model code, designated K8.^[36]

On the LS (pictured), "barn doors" are used to access the rear, whereas the LT utilises a two-part tailgate.

The Holden's interior differed from that of the American version, whereby the dashboard of the Chevrolet Blazer was used instead. However, it had to be stretched to fit in the larger Suburban. A bench seat came standard on the entry-level variant as well as the LS, but the more expensive LT received bucket seats. With the omission of the centre seat, the LT has a maximum seating capacity of eight, compared to nine.^[37]

Creature comforts standard in all models included a LCD compass in the rear-view mirror, a tilt adjustable steering wheel, a driver's airbag, ABS brakes, and dual-zone air conditioning.^[37] An extra A$5,000 would buy the second tier LS, bringing alloy wheels, power windows and mirrors among some features. To further up the ante, the LT gained electric front seats, leather trim, and a horizontally slated, two-part tailgate. This came as opposed to the "barn doors" found on the other specifications.^[38]

Reaching almost 5.6 metres (18 ft) in length, the Suburban is longer than almost all long-wheelbase luxury sedans.

The Suburban was offered with the choice of either a 5.7-litre Vortec V8, producing 190 kilowatts (250 hp) and 447 newton metres (330 ft·lbf) of torque, or a 6.5-litre turbodiesel V8 outputting 145 kilowatts (194 hp) and 583 newton metres (430 ft·lbf).^[37] The former choice was designated the "1500" name, while the turbodiesel saw the "2500" identify.^[38] The 5.7-litre petrol engine is LPG-compatible, and such systems can be retrofitted if desired. Regardless of the engine specified, the car was equipped with a four-speed automatic transmission. However, what differed was the type of transmission. Petrol motors were fitted with the GM 4L60-E transmission, with the GM 4L80-E reserved for the diesel.^[35] A dashboard switch allows the vehicle to power all the wheels simultaneously, or just the rear-wheels, and even allows for the low range gearing to instigate.^[37]

The vehicle's fuel efficiency has been rated at 19.7 L/100 km (11.9 mpg_-US) for the diesel specification,^[39] with that figure rising to 21.8 L/100 km (10.8 mpg_-US) for the petrol model.^[40] With the hefty fuel consumption comes a 159-litre fuel tank.^[37]

To combat the extra payload and towing capacity of the diesel, an improved braking package, as well as super heavy duty axles and suspension were fitted. Holden recommends a maximum 3,400 kilogram (7,496 lb) towing limit for the turbodiesels, with a reduced figure of 2,720 kilograms (5,997 lb) for the petrol models.^[37]

GMT800 GMC Yukon XL

GMT800 GMC Yukon XL Denali

Suburbans in U.S. President George W. Bush's motorcade, 2008

The GMT800-based Suburbans were introduced in late 1999 for the 2000 model year. They were sold in two series: 1/2-ton 1500 and 3/4-ton 2500. Suburbans came in Base, LS and LT trims. Optional was pushbutton 4-wd with low-range transfer case. A tow hitch with trailer wiring plug was optional.

For 2000, Chevrolet's long-serving 5.7 L and 7.4 L V8 engines were retired along with the 6.5 L diesel. New engines were 5.3 L (325 cu in) the 1500 series and 6.0 L (364 cu in) for the 2500 series.

New features included:

• A spare tire relocated beneath the vehicle (instead of in the cargo area as on previous models)
• "Puddle lamps" in the exterior mirrors on LS and LT models
• New instrument panel including a driver message center and engine hour meter
• Electronic climate control available on LT models
• Four-wheel disc brakes
• Load-leveling Autoride suspension available on LT models
• Premium Ride rear self-leveling suspension available on LS models

For 2001, the 6.0 L V8 in 2500-series Suburbans gained 20 hp (15 kW) from a number of changes including aluminum cylinder heads. A new 8.1 L (496 cu in) V8 was added as an option for the 2500 as well. OnStar became standard on LT models and LS models with the new Z71 package. Quadrasteer four-wheel steering was added as an option on 1500 series trucks.

2002 saw several optional features made standard equipment on the LS model, including front and rear air conditioning, alloy wheels, power windows, power front seats, side steps, fog lamps, and heated outside rear view mirrors. Base models were discontinued, leaving LS and LT.

The 5.3 L V8 in the 1500 series added flex-fuel capability. The 6.0 engine was not available in the 1500 series.

For 2003, all GM full-size trucks received an upgraded interior, with better-quality materials and other enhancements. New radios offered Radio Data System compatibility, XM satellite radio, Bose sound and improved ergonomics. Adjustable pedals were added as an option, and the instrument cluster-mounted Driver Information Center was improved and monitored up to 34 vehicle functions. A Panasonic DVD system was added as an option. GM's Stabilitrak system was added, and Quadrasteer became available on 2500 series Suburbans. Towing capacity for Quadrasteer-equipped vehicles was reduced by 300 lbs (the weight of the system).^[42]

For 2004, 1500-series Suburbans received the Hydroboost braking system that was previously introduced in the 2500 series.

The Mexican-market Suburban received a front end update this year, matching that of the Silverado.

The 2005 model year saw the long-standard side-hinged panel doors discontinued in favor of the formerly optional liftgate. All engines switched to an all-electric cooling system to reduce power loss and fuel consumption.

The Z71 package, long exclusive to 4wd models, became available on 2wd Suburbans. OnStar also became standard across the board.

Finally, Stabilitrak became standard on all models shortly after the start of the model year.

For 2006, the GMT800 Suburban's last year, a special LTZ trim package became available, featuring 20-inch (510 mm) wheels, all-wheel drive, and the LQ4 6.0 L engine of the 2500 series of trucks and SUVs.

The catalytic converters were relocated closer to the engine. The XM radio antenna and the OnStar antenna were combined into a single unit.

Engines

2010 GMC Yukon XL SLT

GMT900 GMC Yukon XL Denali

The 2007 model year Suburban and Yukon XL were unveiled at the 2006 Los Angeles Auto Show in January. Production of the redesigned GMT900 Suburban and Yukon XL began at Janesville Assembly and Silao Assembly in January 2006 (Suburban) April 2006 (Yukon XL), with the vehicles arriving at dealerships in April.

The new models were redesigned with more modern, less boxy styling,^[43] already seen on the previously released 2007 Tahoes and Yukons. The exterior features a more aerodynamic shape, made partly by a steeply raked windshield angle. The new design is more aerodynamic.

The interior has a redesigned dashboard and improved seats. It still retains its 9-passenger seating availability, which is available on LS models only. LT2, and LT3 models have leather seating and available 6-, 7-, and 8-passenger seating. There is a Z71 package available on LT2 and LT3 models which includes two-tone leather seats. All Mexican-built Suburbans including the 9-seat models offer the special two-tone leather seating used by the Z71. The Suburban LTZ comes standard with a DVD player,GPS navigation enhanced radio that is touch screen.

For the 2010 model year, in which U.S. News & World Report ranked it as the number one affordable large SUV,^[44] the Suburban added a premium interior package that includes tri-zone climate control and handy features like Bluetooth and rear audio controls. In addition, radios that are standard in all 2010 trims get a USB port, allowing for music to be played from auxiliary devices though the radio, as well as charging other small electronics. The 6.0 liter engine in the 2010 models will also be flex fuel capable. Minor front end changes including a slightly raised front bumper and side torso air bags were also made standard for 2010.

In February 2010, Chevrolet unveiled a 75th anniversary edition of the Suburban, which will have the LTZ trim with white diamond tricoat exterior paint and cashmere interior, along with standard 20-inch chrome-clad wheels, revised roof rails, integrated navigation radio, XM Satellite Radio, Bluetooth phone connectivity, rearview camera, rear park assist, remote starting, adjustable pedals, and leather upholstery with heated/cooled front seats. Chevrolet says that the anniversary edition will be limited to 2,570 units because of the amount of white diamond paint GM can procure.^[45]

The 5.3 L and 6.0 L engines carried over, and a new 403 horsepower (301 kW) 6.2 L Vortec V8 was added for the Yukon XL Denali. The 8.1 L engine was dropped.

For the 2011 model year, the Suburban will add three new exterior colors to the lineup: Mocha Steel Metallic, Green Steel Metallic, and Ice Blue Metallic. The trims will also get an updated modification, with the rear audio system, Bluetooth, floor console/storage area, wood grain interior, luggage rack rails, body-color exterior door handle/mirror caps and premium-cloth front bucket seats now standard on the 1LS trim, and chrome recovery hooks, two-speed transfer case, and 20-inch chrome wheels standard on its 1LS 4WD models. In addition, the trailering package will feature the trailer brake controller as a standard on all trims.^[46]

For the 2012 model year, trailer sway control and Hill Start Assist become standard on all trims, while the LTZ trim added a heated steering wheel and Side Blind Zone Alert as a standard.^[47] Also, the LT1/2 options for the Suburban and SLE1/2 and SLT1/2 options on the Yukon XL were discontinued, leaving the Suburban with only a LS, LT and LTZ trim and the Yukon XL with a SLE and SLT trim. On March 30, 2012, GMC celebrated its 100th anniversary by releasing a special edition of its Yukon XL, offering a Heritage Edition trim package.^[48] This would also be the final year that three colors, Graystone Metallic, Gold Mist Metallic and Blue Topaz Metallic, would be offered, along with the all season blackwall P265/65R18 tires.

For the 2013 model year, two new colors were offered: Champagne Silver Metallic and Blue Ray Metallic (extra charge). Also new is Powertrain Grade Braking, normal mode. The 2013 arrived for Chevrolet dealers in June 2012.^[49]

For the 2014 model year, power-adjustable pedals, remote vehicle starter system and rear parking assist along with rear vision camera and inside mirror with camera display will become standard on the Suburban LS trims. In addition, Concord Metallic (which was supposed to be available for the 2013 MY) will be added to the Suburban color offerings for the 2014 models.^[50] For the Yukon XL, a convenience package will now become standard on its SLE models, along with a new color, Deep Indigo Metallic.^[51] In February 2014, The Suburban came in second behind the Tahoe among the top-ranked large affordable SUVs by U.S News & World Report.^[52] This would be followed by being acknowledged as an award recipient in the large SUV category by JD Power and Associates in July 2014.^[53]

The three-quarter ton model's towing capacity is 9,600 lb (4,400 kg), being one of the best of any 4x4 SUV and matched only by the Toyota Sequoia's towing capacity. The three-quarter ton model also has a GCVW of 16,000 lb (7,300 kg).

The 2500 Suburban was originally sourced from Silao, Mexico from 2007 to 2008 but was moved to the Arlington, Texas assembly plant for the 2009 model year, where production of all GM fullsize SUVs was consolidated after the closing of the Janesville plant.^[54][55]

GM discontinued the 2500 3/4 Ton versions of both Suburban and Yukon XL models after the 2013 model year.^[56][57]

The eleventh generation Suburban's design provided the basis for the Declasse Granger and its law enforcement counterparts, a line of fictitious SUVs that are featured in the Grand Theft Auto video game series as of Grand Theft Auto V.

2015 GMC Yukon Denali XL at the Rochester International Auto Show.

On September 10, 2013, GM announced that the twelfth generation Chevrolet Suburban, GMC Yukon XL, and Yukon Denali XL would be introduced to the public on September 12, 2013,^[59] and unveiled the vehicles in different locations (The Suburban in New York, Yukon XL in Los Angeles) on that date.^[60] Both vehicles are based on the GMT K2XX platform and will carry unique serial designated numbers, identified by platform (K2), brand (YC for Chevrolet, YG for GMC), drivetrain (C for 2WD; K for 4WD), tonnage (15 for half-ton, 25 for 3/4-ton, 35 for 1-ton), wheelbase (7 for short, 9 for long), and 06 for SUV, which means that a K2YC-K-15-9-06 would be identified as a Chevrolet Suburban 1500 4WD.^[61] The Suburban and Yukon XL went on sale in February 2014 as a 2015 model,^[62][63] with the vehicles built exclusively in Arlington, Texas.^[64]

Production details

The first reveals came on April 10, 2013 when Motor Trend posted the first spy shots of GM's large SUV lineup, using front covers borrowed from the Ford Expedition to throw the competition off.^[65] Then on May 15, 2013, more spy shots of the next generation Chevrolet Suburban/GM Yukon XL, which was expected to have the same frontal design as the Silverado but would have a more boxy style than the previous generations, were unveiled.^[66]

On September 12, 2013, GM released the photos and press release of the newly redesigned Suburban and Yukon XL, and was later showcased to the public for the first time on September 27, 2013, at the State Fair of Texas.^[67][68] This move comes on the heels of the 80th anniversary of the first production of the Suburban in 1934.

The designs and concepts were created by GM's exterior design manager Chip Thole (prior to his transfer to GM's Buick design studio in 2013), who told Truck Trend in a February 17, 2014 interview "I start with what intuition tells me about the market and get the team going on that. You look at trends around the industry – fashion, culture, what people are buying, what they say they want now – and project that into the future. The fun part is putting those ideas to paper and going from there." He then added "We wanted to take what was good about today's vehicles, bring that forward and make them new and different with that spark of freshness that people recognize, without making them gimmicky or overdone." Thole also challenged his design team to help bring ideas to the SUVs, which lead to the split headlamps and a more graphic feel for the Suburban design, while a more industrial but sculptured look was added to the Yukon XL to give it a unique identity of its own.^[69]

Production on the Suburban and Tahoe began in December 2013 with the first completed SUVs being used for testing purposes.^[70] GM then officially started shipping the vehicles to dealerships on February 5, 2014.^[71] It is estimated that it takes 8–10 weeks to assemble the SUVs, save for the upgrades on the level trims and destination scheduling.^[72]

Chevrolet introduced the designs, choices and build-your-own features for the 2015 models on its website in January 2014 with a set price starting at $47,000 (2WD) to $50,000 (4WD) for the LS trim, $52,000 (2WD) to $55,000 (4WD) for the LT trim, and $61,000 (2WD) to $65,000 (4WD) for the LTZ trim.^[73][74][75] The pricing on GMC's Yukon XL's are set at around $49,000 (2WD) to $52,000 (4WD) for the SLE, $57,000 (2WD) to $60,000 (4WD) for the SLT, and $65,000 (2WD) to $68,000 (4WD) for the Denali trims.^[76]

Features

The front fascias of the Chevy Suburban and GMC Yukon XL are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, improving aerodynamics, fuel economy, and lessens interior noise. The hoods and liftgate panels are made of aluminum in an effort to reduce vehicle weight, and the wiper blades that was located on the liftgate door is moved to the rear spoiler located on the top of the rear liftgate window. Also noticeable is the SUV's length, which expands from 222.4 in (5,649 mm) to 224.4 in (5,700 mm) (the Yukon XL's length is shorter at 224.3 in (5,697 mm)) and its width from 79.1 in (2,009 mm) to 80.5 in (2,045 mm), while the height decreases from 76.8 in (1,951 mm) to 74.4 in (1,890 mm), thus allowing the vehicle to become slightly leaner, a little bit wider, more streamlined, and roomier.

A more-efficient, direct-injected EcoTec3 V8 powertrain (5.3 for the Suburban, 6.2 for Yukon XL/Yukon Denali XL) coupled with improved aerodynamics, helped the SUVs offer greater estimated highway fuel economy and improving its MPG and CAFE estimates to 16MPG (City)/23MPG (Highway)/18 (Combined) for 2WD, and 15MPG (City)/22MPG (Highway)/18 (Combined) for 4WD.^[77] The increased MPGs also vaulted the Suburban/Yukon XL into the top spot among large SUVs with the most efficient MPG rating numbers for this segment.^[78] However, when Motor Trend (which placed the 2015 Suburban on the front cover of its June 2014 issue) did a road test review on the SUVs on April 3, 2014, it estimated the 4WD MPG on the Suburban LTZ to be slightly better at around 15.2 City and 22.3 Highway, while the 4WD Yukon Denali XL, whose MPG is rated at 14 City/20 Highway, was estimated lower at 12.4 City and 19.2 Highway.^[79]

Like the 2007–14 version, both the Suburban and Yukon XL do not share a single piece of sheetmetal or lighting element with the brands' full-size pick-up trucks, and the front grilles of both vehicles are slightly altered to give it their own identity. The front headlights features projector-beam headlamps that flanks the Chevrolet-signature dual-port grille – chrome on all models, sweeping into the front fenders, while the LTZ trims features high-intensity discharge headlamps and light-emitting diode daytime running lamps. The Yukon XL also feature projector-beams on all trims as well. The improved safety features included a 360-degree radar detection for crash avoidance and occupant protection and a high-tech anti-theft system that now includes vertical and interior sensors, in-glass and window breaking, a triggering alarm and a shutdown device that prevents the vehicle from moving. The latter is expected to address the issues regarding the constant thefts of the vehicles, especially with the previous generation's removable seats and items left in the cargo space, which has become a target for carjackers who see the third row seats as valuable on the black market.^[80] According to General Motors' head of Global Vehicle Security Bill Biondo, "We have engineered a layered approach to vehicle security," adding that "With new standard features and the available theft protection package, we are making the vehicles less attractive target to thieves and more secure for our customers."^[81]

Also new are the addition of fold-flat second and third-row seats (replacing the aforementioned removable third seats), which is now a standard feature but can be equipped with an optional power-folding feature for the upgraded trims, and an additional two inches of leg room for second-row passengers. HD radio became a standard feature on all trims. Multiple USB ports and power outlets are now spread throughout their interiors, including one 110-volt, three-prong outlet on both Suburban and Yukon XL, with the Suburban adding an available eight-inch color touch screen radio with next-generation MyLink connectivity along with an available rear-seat entertainment system with dual screens and Blu-ray DVD player, while the Yukon XL adds a standard eight-inch-diagonal color touch screen radio with enhanced IntelliLink and available navigation. A 4G LTE WiFi access system, along with Siri Eyes Free and text messaging alerts, was included into all vehicles that feature the OnStar device around the second quarter of 2014.^[82][83]

The Yukon XL interior has more additional features that includes seats stuffed with dual-firmness foam, a standard Bose sound system and SD card slots, and laminated glass for the windshield and front windows, decreasing interior noise. The Denali Yukon XLs comes equipped with active noise-cancellation technology, with GM's third-generation magnetic ride control suspension as a standard feature, which is only featured on the Suburban LTZ models, whose upgraded features also includes a real-time damping system that delivers more precise body motion control by "reading" the road every millisecond, and changing damping in just five milliseconds.

The Suburban will have eight color palettes to choose from for the 2015 model year: Champagne Silver Metallic, Silver Ice Metallic, White Diamond Tricoat, Sable Metallic, Crystal Red Tricoat, Summit White, Tungsten Metallic, and Black.^[84] The GMC Yukon XL palettes will be available in nine colors: Onyx Black, Summit White, Quicksilver Metallic, Champagne Silver Metallic, Iridium Metallic, Bronze Alloy Metallic, Crystal Red Tintcoat, White Diamond Tricoat, and Midnight Amethyst Metallic. The latter three will be the most expensive color trim options.^[85]

On August 29, 2014, Chevrolet announced that the Z71 package would return with a launch by leaking a photo that displayed the Z71 badge on one of its large SUVs.^[97] On September 26, 2014, Chevrolet debuted the updated Z71 Suburban at the State Fair of Texas, along with the debut of the Texas Edition Suburban, the latter due to Texas having the largest units of Suburbans sold in the United States (As of August 2014, sales of the Chevrolet SUVs in Texas was up 37 percent) and to celebrate the 60th anniversary of GM's Arlington Assembly plant; production of the Z71 Suburban began in October 2014.

As with the previous Z71 Suburbans, this version continued to be offered in a 4WD LT trim only, featuring a front skid plate, off-road tires mounted on 18-inch wheels, a unique grille, running boards and "Z71" identification inside and out. Fog lamps, front tow hooks and front parking assist are also included. The 2016 Z71 package was modified again, as portions of the Z71 items added on the Texas Edition package as an optional feature by request from customers was discontinued, making it a stand-alone package.

The Texas Edition Suburban, which became part of the Texas Edition lineup along with the Tahoe and Silverado, was available in both LT and LTZ trims for the 2015 model year, featuring a maximum trailering package, twenty-inch polished aluminum wheels (on LT models), twenty-two-inch premium painted aluminum wheels (on LTZ models), and an exclusive "Texas Edition" badge.^[98] For the 2016 model year, Chevrolet discontinued the LTZ package but modified for the LT package without the requested Z71 features.

2500HD and 3500HD Suburban

In a March 25, 2014 interview with Four Wheeler, GM stated that it is not offering the 3/4 ton version or a 1-ton version in the 2015 model due to soft sales that resulted in GM discontinuing the 2500 Suburban/Yukon XL series after the 2013 model year.^[99] But on October 5, 2014, The Fast Lane revealed spy shots^[100] that were taken from an undisclosed location in Colorado in which a prototype Suburban was spotted with wheel caps, the same caps that are featured on the Silverado 2500HD trims, and an exhaust system that points to the gas motor. While Chevrolet has yet to reveal any details, it is projected that there are plans to add a 2500HD version of the Suburban, whose features would also include either a 6.0L or 6.2L V8 engine along with a performance enhancement, as a possible entry for 2016. This move would mark the return of the 3/4-quarter ton (aka the 2500 version) Suburban after GM discontinued it after the 2013 model year.

On March 19, 2015, Chevrolet confirmed reports from auto websites that a 2500HD Suburban will be available in 2015 as a 2016 model, as evidenced by a VIN-assigned document that was obtained by the website Cheers & Gears. However, this version, identified as a Class 3 vehicle (around 10,000 to 14,000 pound GVWR), will only be available for sale to rental companies and commercial fleet entities as a 4WD vehicle and will use the same design as the twelfth generation version, but will use a different engine altogether. The 2500HD Suburban will only be offered in LS and LT trims, reserving the LTZ trim for a more luxurious offering (like limousine or taxi-related services). There will be no rear-wheel drive or upgraded packages. In addition, there are no plans to offer a 3/4-ton GMC Yukon XL as GM is making the design exclusive to Chevrolet for the time being.^[101][102]

On June 23, 2015 GM confirmed that a one-ton "Suburban 3500HD," which would be a GM-unique SUV, will be introduced for the 2016 model year. This will be government-exclusive and available in 4WD LS and LT trims only, weighing around 11,000 pound GVWR, 17-inch machined aluminum wheels (8 lug), a high capacity air cleaner, 220 amp alternator, external engine oil cooler and auxiliary transmission cooler. Although the vehicle has a high GVWR, it is configured to provide a minimal towing capacity and is primarily intended for conversion to an armored vehicle. This version will not include HD radio, nor there will be a GMC Yukon XL equivalent, making this version exclusive to Chevrolet as well.^[103]

Additional changes and upgrades

On September 18, 2013, Chevrolet stated that there would be no diesel variant of the full-size SUVs planned for the 2015 model year.^[104] GM, however, will offer another off-road variant or trim for the Suburban and Yukon XL starting with the twelfth generation, which is in the planning stages.^[105] With the relaunch of the Z71 package in the Suburban, GM announced on January 26, 2015 that it has filed papers to trade mark the Trail Boss name for use on future Chevrolet truck and SUV models.^[106]

One concept design for the Suburban called the Half-Pipe, whose features include roof racks and crossbars to mount skis, was featured at the SEMA Show on November 4, 2013; its parts will be available for order at Chevrolet Accessories.^[107] This would later be followed by a video chat from GMC about the Yukon XL on November 6, 2013, which confirmed that the reason for the safety and fuel economy was the catalyst for GMC to no longer offer an AWD in the Yukon Denali XL and added that there will be no volume controls or devices in the rear seating area to operate the DVD system.^[108] On February 12, 2014, Callaway Cars announced that it will add an upgraded supercharged package to the Suburban for an additional $17,000.^[109]

On September 25, 2015, Corsa Performance added a cat-back exhaust system package for customers looking to upgrade their K2XX Suburban or Yukon XL, which would give the 5.3L versions a 669% flow increase and the 6.2L versions a 342% flow increase.^[110]

Reviews and reception

The news of the redesigned Suburban and Yukon XL have so far been met with positive reviews from automotive critics who praised GM's devotion and commitment to keeping the Suburban and its sister SUVs in production due to their popularity and sales.^{[111][112][113][114]}

A test drive that was done on February 25, 2014 received positive reviews for its speed, handling, technology, and performance from The Fast Lane,^[115] and an overall 9 rating (out of 10) from Canada's Autonet.ca.^[116] Truck Trend quoted that they never really thought of the Suburban and Yukon XL as "one-percent" vehicles (referring to their previous generations and its upper-class and family-oriented customers), they're now solidly "ten-percenters" with the updated versions.^[117]

However at the same time it has seen mixed comments from message boards like Autoblog and Chevrolet's Facebook page, mainly about the front grille, its boxy design, GM's decision to not include additional or optional features to the Suburban, like a Duramax engine, and the conspicuous absence of the "2500" (or 3/4 ton) version in the current production lineup or making it available for sale to the public. In a review from Automobile Magazine, writer Greg Migliore notes that despite the reception from both sides and the possibility that other automakers might exit the large SUV segment, that with this 12th generation, "GM is clearly hoping the Suburban makes it to the century mark."^[118] The Detroit News gave the 2016 Suburban LTZ a 4 star (excellent) rating, this after comparing the SUV with the Fiat 500L in an experimental test inspired by Pope Francis' 2015 visit to North America, in which the Pontiff used the 500L, which is the equivalent of the President of the United States' armored Suburban^[119] The 2016 model also got a workout of sorts at the Florida International Rally & Motorsports Park to test its abilities on the racetrack, where it performed successfully.^[120]

The 2015 Suburban was ranked third among the top affordable SUVs and fifth among affordable SUVs with 3-row seats by U.S. News & World Report,^[121] and was among the finalists in Motor Trend's SUV of the year for 2015.^[122] It also received a 2015 MotorWeek Drivers' Choice Award for best large SUV,^[123] while Consumer Reports ranked the Suburban as the best SUV with a third row seat, topping its competitors in this category.^[124]

Sales

The interest in the redesigned twelfth generation Suburban has also translated into surging sales. In April 2014 it saw a 109.8 percent spike with most dealers reporting that the vehicles are being sold within 10 days after it arrives on the dealership lots with customers opting for the fully loaded LTZ model, making it one of Chevrolet's fastest selling brands in 2014.^[125] The twelfth generation Suburban is also a hot seller in the Middle East, where in August 2014 posted a 37% increase in sales, with most of the purchases coming from Saudi Arabia (65%), the United Arab Emirates (15%) and Qatar (108%).^[126] By the end of September 2014, GM sold more than 4101 units of the Suburban (up 50.1%), while the Yukon XL posted 2165 units sold (up 64%), with GM boasting that 80% of the vehicles sold were its large SUVs.^[127]

In Canada, sales of the Suburban reached 966 units (up 43%) in 2014, although the Yukon XL is the best seller in that country with 1,760 vehicles sold (up 50.3%) that same year.^[128] Overall, they account for 70 percent of GM Canada's SUV sales for 2014.^[129]

On August 17, 2015, GM confirmed plans to increase production on its large SUVs, especially on the Suburban/Yukon XL, due to lower gas prices and a higher demand for the vehicles. The move also resulted in its Arlington Assembly adding more hours and increasing its production from 48,000 SUVs to 60,000 based on the expanding hours and added Saturday overtime shifts.^[130]

When production of the CUCV II ended in 2000, GM redesigned it to coincide with civilian truck offerings. The CUCV nomenclature was changed to Light Service Support Vehicle in 2001. In 2005, LSSV production switched to AM General, a unit of MacAndrews and Forbes Holdings. The LSSV is a GM-built Chevrolet Silverado 1500, Chevrolet Silverado 2500 HD, Chevrolet Tahoe, or Chevrolet Suburban that is powered by a Duramax 6.6-liter turbo diesel engine. As GM has periodically redesigned its civilian trucks and SUVs from 2001 to the present, LSSVs have also been updated cosmetically.^[131]

The militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook, tow shackles and a 24/12 volt electrical system. The dashboard has additional controls and dataplates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories.^[131] In the Canadian Army these vehicles are nicknamed "Milverado".

The Enhanced Mobility Package (EMP) option adds an uprated suspension, 4-wheel anti-lock brakes, a locking rear differential, beadlock tires, a tire pressure monitoring system and other upgrades. About 2,000 LSSV units have been sold to U.S. and international military and law enforcement organizations.^[131]

For the 2015 model year, the Suburban received an NHTSA rating of 4 stars overall, with the side driver/passenger categories receiving 5 stars. (Because of more stringent tests, 2011 and newer model ratings are not comparable to 1990–2010 ratings.) The NHTSA gave the 2016 models 4 stars overall in its review, similar to its review of its 2015 models.^[133]

It gave the Suburban an Acceptable rating along with the Tahoe and Yukon. The Escalade also got an Acceptable rating.

2000–06 Suburban

The Suburban, Tahoe, GMC Yukon and Escalade a Good rating and a Best Pick. However all four including the Yukon XL got a Good rating for head protection in side and seats and head restraints.

2007–14 Suburban

The Suburban, Tahoe, Yukon and Escalade earned a Good rating in the front offset. However 2007–09 models without side airbags got a Poor rating. Models with them got a Marginal rating. 2010–14 models got a Top Safety pick.

2015–present models

All of the K2XX SUVs received a top safety pick, except for the Chevrolet / GMC 1500 series pickups, which have not been tested. The pickups have been tested against the moderate overlap test, for which they received a good rating.

Recalls

On March 28, 2014, GM announced a recall on the 2015 Suburban and Yukon XL in order to fix a "transmission oil cooler line that is not securely seated in its fitting," causing the vehicle to stop and rupture the oil cooling line, resulting in the engine to malfunction and catching fire immediately.^[136] The move comes on the heels on an incident that happened on March 23, 2014, when a 2015 GMC Yukon caught fire and went up in flames in Anaheim, California during a test drive.^[137] Despite being an isolated incident, the 2015 Suburban and Yukon XL are not tied to GM's announced recall of its vehicles (from previous generation models and discontinued brands that were produced prior to, during, and after, GM's restructuring in 2010) that was made on March 17, 2014.^[138]

On June 6, 2014, GM issued another recall on the 2015 Suburban and Yukon XL because their radio control modules may not work, and thus prevent certain audible safety warnings.^[139] This would be followed two weeks later on June 27, 2014 with another recall, in which the transfer case "may electronically switch to neutral without input from the driver," adding that if this occurs while the vehicle is moving, power will not be sent to the wheels, meaning that if the vehicle is parked, it may roll away unexpectedly if the parking brake has not been set.^[140]

On December 5, 2014 GM announced that it is replacing ignition key units on the 2015 Suburban and Yukon XL after customers made complaints that the shift lever strikes the head of the key if the tilt-adjustable steering column is in the fully up position. The lever only can be moved out of "park" into a gear when the engine is running and the driver's foot is on the brake. The push-button ignition features are not affected.^[141]

On January 4, 2015 GM issued a recall on eleventh-generation Suburbans and Yukon XLs from the 2011 and 2012 model year for a potential ignition lock actuator issue, citing that they're not the right size and can cause the ignition to get stuck in the "Start" position, and then either due to a jarring event or a "cool interior temperature" the ignition could switch back to the "Accessory" position, resulting in a loss of power assistance and prevent the airbags from deploying.^[142]

On December 30, 2015, the NHTSA revealed that it had received complaints from 2015 Suburban/Yukon XL owners about buffeting and vibration problems, which is causing the drivers and passengers to endure an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. GM is aware of this and has moved to correct the situation and try to pinpoint the source, but assures the vehicles are safe to drive.^[143]

Yearly American sales

Beginning in 1999, GM re-branded the GMC Suburban as the Yukon XL.
