One of the most impressive debut at Ferrari’s stand in Beijing was an evolution of the HY-KERS project adapted to a mid-rear engine layout. This new system combines a 12-cylinder engine and dual-clutch gearbox coupled to an electric motor. A second electric motor is dedicated to the auxiliary systems and is located in front of the V12. The two electric motors will take its power from batteries which can be positioned in the car in line with the available space and final configuration.
The KERS features new, smaller and lighter electronic components which come close to achieving the declared target of 1 KW per kg of extra weight added by the hybrid system.
The electric motor will deliver the power using one of the gearbox’s two clutches and is mated to one of the two main shafts. During braking, the electric motor acts as a generator, using the kinetic energy from the negative torque to recharge the batteries. This crucial task is managed by a dedicated ECU, also F1-derived, which not only controls the electric motor, but also governs the power to the auxiliary systems.
