The SF90 Spider features a plug-in hybrid architecture where the internal combustion engine is integrated with two electric motors at the front, which make up the RAC-e (electronic cornering set-up regulator) system.
There is also one at the rear which is derived from and takes the name MGUK (Motor Generator Unit, Kinetic) from the Prancing Horse's Formula 1 experience. The synergy between the internal combustion engine and the electric motors makes it possible to reach a maximum power of 1000 hp and puts the SF90 Spider at the top of the category and the Maranello-based company’s range.
Thanks to its 780 hp (and 195 hp/l specific power), the SF90 Spider's internal combustion engine is at the top of the Ferrari range. The technicians focused on redesigning the intake and exhaust system to achieve this result. In the new configuration all the ducts are almost horizontally lined up at cylinder head height, the turbocharger unit has been lowered and the exhaust line is higher. This streamlining has resulted in a lower centre of gravity and a reduction of the overall weight, also thanks to the use of Inconel® in the exhaust pipe.
In the SF90 Spider, the Manettino is complemented by a selector (eManettino) with four modes for managing the hybrid system: eDrive, Hybrid, Performance, Qualify.
Innovative aerodynamic solutions include the shut-off Gurney, an active system at the rear of the car that adapts to driving conditions. The vehicle dynamics control logic, now called electronic Side Slip Control (eSSC), has also been enhanced: the system continually checks the car's dynamic conditions and independently manages the torque applied to the inner and outer wheel (Torque Vectoring). The eyes on the road, hands on the steering wheel philosophy has resulted in a new human-machine interface (HMI) full of innovations, including a steering wheel with touch controls and a fully digital central cluster with a 16" curved HD screen.
