The 6262 cm3 V12 engine is equipped with two new camshafts, mechanical (instead of hydraulic) distribution of the valves, which have been changed accordingly, specific engine mapping, re-designed intake ducts with a different polishing treatment, and an overhauled exhaust line, which has seen the elimination of the silencers.
The HY-KERS system has been developed with a focus on pure performance, with operational logics that can be managed by the driver via a special 4-position manettino: Qualify, to obtain the maximum performance within a limited rpm; Long Run for optimising performance consistency; Manual Boost for instantaneous delivery of the maximum torque; Fast Charge, to activate fast battery charging.
A dual pair of lateral turning vanes and vertical fins serve to direct the air towards the flanks of the car, funnelling the wake from the front to the outer part of the underbody. This is sealed by the body skirts that extend from the sill, creating the advantage of a considerable reduction in resistance, along with an increase in aerodynamic load resulting from the more effective use of the aerodynamic underbody.
The rear end of the car is also highly sophisticated, with the raised tail of the bodywork and the mobile rear spoiler, the length of which is extended, with a total increase of 60 mm in maximum extension. Two “candelabri” (small wing profiles), consisting of a vertical fin and a horizontal profile, act to provide drift in a low-resistance configuration, whilst in a high load configuration, they amplify the performance of the spoiler. Furthermore, this system generates powerful suction forces at the rear of the car, helping, among other things, to take full advantage of the flat part of the underbody in front of the rear wheels, thanks to two by-pass ducts that reduce the pressure inside the wheel compartment. The rear diffuser, which is extremely wide, optimises air extraction from the vehicle underbody.
The result is a 50% improvement in the downforce in the low resistance configuration, and a 30% improvement in the more extreme downforce configuration, which reaches 540 kg at a speed of 200 km/h.
