The V12 Engine
The Ferrari 599 GTB Fiorano's engine is a 65° V12 with a 5999 cm3 displacement that delivers a specific power output of 103 hp/litre. Its architecture was derived directly from the Enzo's. A further development of the same engine, this time for track-only use, was used on the recent Ferrari FXX also. The basic architecture of the Enzo engine was retained (block, cylinder heads, sump and combustion chamber geometries) while new components and subassemblies were designed to yield high engine revs, significantly reduce weight and optimise its distribution,and yield a more compact power unit.
The result is that the new engine is mounted in the mid-front position and delivers enhanced performance and reduced fuel consumption whilst complying with the very latest emission standards. The engine, known in-house as the F140C, has a completely different structure from the one that powered the previous generation of Ferrari 12-cylinder berlinettas, the 550 and 575M Maranello. It delivers absolutely stunning driving pleasure thanks to incredibly smooth power delivery and the wonderful signature engine sound.
The maximum engine speed - 8400 rpm (+900 rpm on the 575M Maranello, an increase of 12%) - is one of the highest achieved by a car of this displacement and in fact is comparable only to that of the Enzo. In other words, it sets a whole new benchmark in terms of sportiness and driving pleasure. The engine's specific power output of 103 hp/litre (13 hp/litre more than that of the 575M, +14%), is the highest achieved by a naturally aspirated engine of this displacement and provides further proof of the fluid dynamic efficiency of the unit. The latter is guaranteed under all conditions by chain-driven distribution and twin overhead camshafts per cylinder bank with hydraulic tappets and continuously variable timing on both inlet and exhaust cams to optimise torque delivery. The inlet tracts were also optimised too. Exceptionally smooth power delivery right across the range up to 620 hp at 7600 rpm (+105 hp or +20% on the 575M) guarantees easy handling and vehicle control at all times.
