The A40 Somerset is an automobile that was produced by the Austin Motor Company from 1952 until 1954. The Somerset replaced the Austin A40 Devon and as a body-on-frame car it was comparable in size to its predecessor. It shared a number of components with the Devon which included a similar 1.2 Litre straight-4 pushrod engine. The Somerset's engine was updated to produce 42 hp (31 kW),[5] compared to the Devons 40 hp (30 kW), giving the car a top speed of 70 mph (110 km/h).

Engineering

The Somerset features an updated "Transatlantic" body style with flowing lines as distinct to the Devons bulky looking body. Resembling the larger Austin A70 Hereford, its design was aimed at improving export sales, particularly to America. Initially offered only as a 4-door saloon, a 3-passenger 2-door convertible, of the same body style was introduced in late 1952. The convertible replaced the earlier Austin A40 Dorset.[6]

The body of the convertible was made by Carbodies of Coventry and was marketed as the Austin A40 Somerset Coupé. This particular style was also known as a 'drophead' coupé in the United Kingdom.[1] The convertible differed from the saloon in having separate front seats that folded forward to give access to the rear. An additional variant known as the Austin A40 Sports, also a convertible, completed the range. This model was carried over from the earlier A40 Devon and Dorset range but which was discontinued with the arrival of the Somerset Coupé.

In 1953 the Austin Motor Company produced a "special" version of around 500 Somerset saloons using the more powerful engine from the 'sports' model which incorporated twin SU carburettors in place of the single Zenith downdraught type. This vehicle featured different interior appointments and two-tone paintwork to set it aside from the standard offering. The Austin Somerset Special had a top speed of 74 mph (119 km/h) while the normal saloon could reach up to 70 mph (110 km/h).

The standard Somerset interior contained two close fitting front seats, finished in leather, which could be arranged as a bench seat and a large deeply cushioned rear bench seat which could accommodate three passengers. With a centrally mounted dashboard or instrument panel, Austin incorporated a four speed, plus reverse, gearbox into the cars design which was controlled by a column mounted gear change lever. Four wheel, foot operated hydraulic brakes and a handbrake operating on the rear wheels only provided the cars stopping power.[7]

Performance

Austin A40 Somerset (ca 1953) at Schaffen-Diest 2013

A sports convertible version of the A40 tested by The Motor magazine in 1953 managed a top speed of 74 mph (119 km/h) and could accelerate from 0-60 mph (97 km/h) in 28.6 seconds. A fuel consumption of 30.1 miles per imperial gallon (9.4 L/100 km; 25.1 mpg-US) was recorded. The test car cost £705 including taxes. These figures were all obtained on the contemporary low octane fuel.[5]

The Austin A40 Somerset saloon's reputation for being somewhat slow and lumbering to drive is not wholly deserved. This solid vehicle had to endure poor quality petrol supplies (1952) and in consequence had retarded ignition settings to tolerate the low octane rating of the fuels available to avoid the engine knocking or 'pinking' condition that was well known in those times. In fact British Motor Corporation later produced a kit to improve the performance and fuel consumption of these cars once premium fuel supplies resumed under the popular petrol brands. This kit comprised a replacement distributor and an optional head gasket for the cylinder head that was thinner and therefore raised the compression slightly from the standard 7.2:1.

An Autocar magazine road test published 18 April 1952 achieved a maximum of 66 mph (106 km/h) (mean) and 71 mph (114 km/h) (best), and a 0-60 mph acceleration of 36.6 seconds whereas the example registered new in February 1954 and given a Used Car Test published in the Autocar series dated 8 April 1960 returned a 0-60 mph time of just 27.9 seconds. The standing quarter mile was down from 24.4 secs to 23.2 secs a marked improvement on the former result taken in 1952 and directly comparable with the Mini 850 launched in 1959, that was considered to be fairly brisk then.

Production

Over 173,000 Somerset's were sold before it was replaced by the A40 Cambridge in 1954. Of that number 7243 were convertibles.[8]

In December 1952 an agreement was signed with the Japanese automobile company Datsun to build Austin vehicles under license using Complete Knock Down Kits (CKD) supplied from the UK. In April 1953 the first Japanese assembled Somerset's rolled off the assembly line ready for sale on the local market to which it was restricted. Assembly ceased in November 1954 when the factory switched to the A50 Cambridge.[9]
