Engine
The vehicle has an aspirated 8-cylinder
engine with a displacement of 4.3 litres,
which produces a power of 490 HP and a
torque of 465 Nm.
The high performance of the engine is
achieved through some technical solutions
in part derived from racing vehicles:
• variable timing with continuous high-
pressure timing variator and dedicated
pump on each camshaft;
• chain-driven timing control (one per
bank) with hydraulic tensioners;
• four overhead camshafts (two per bank)
and four valves per cylinder driven by
hydraulic tappets with automatic backlash
recovery;
• cylinder heads with combustion chamber
of high volumetric and thermodynamic
ef ciency;
• aluminium alloy and hardened silicone
crankcase with wet Nickasil-coated
aluminium liners;
• single-piece crankshaft in hardened steel,
individually balanced, resting on ve
main journals with bushings;
• dry sump and oil/water exchanger
incorporated in the crankcase, in the
centre of the two cylinder banks;
• motor-driven accelerator throttle (drive
by wire) and integrated Bosch Motronic
ME7 ignition/injection system.
