Chronology
Predecessor Ferrari/Maserati F136 V8 engine

The Ferrari F154 is a family of modular twin-turbocharged, direct injected V6 and V8 petrol engines designed and produced by Ferrari since 2013. It is a replacement for the naturally aspirated Ferrari/Maserati F136 V8 family on both Maserati and Ferrari cars. They are the first turbocharged Ferrari road engines since the 1987 2.9-litre F120A V8 of the Ferrari F40.[1]

Description

The F154 V8 engines have a 90° angle between the cylinder banks, aluminium block and heads. The forced induction system uses two parallel twin-scroll water-cooled turbochargers supplied by IHI[1] and two air-to-air intercoolers. The valvetrain consists of 32 valves actuated through roller finger followers by two overhead camshafts per bank; the timing chain is located on the flywheel side. All versions feature gasoline direct injection and continuously variable valve timing on both intake and exhaust side.

The Ferrari version of the engine has a flat plane crankshaft and dry sump lubrication. In order to obtain equal length pipes, the exhaust manifolds are manufactured from multiple welded cast steel pieces; the turbocharger housing uses a similar three-piece construction.[1]

The Maserati version has a crossplane crankshaft and wet sump lubrication. Turbine housings and exhaust manifolds are integrated in a single piece. On the Quattroporte, the engine has an overboost function which raises maximum torque from 650 N·m (479 lbf·ft) between 2000 and 4000 rpm to 710 N·m (524 lbf·ft) between 2250 and 3500 rpm.[2]
