The Ferrari F12 Berlinetta has made its Asian debut at the Beijing International Motor Show. The premiere is accompanied by a world premiere of the evolution of the HY-KERS laboratory concept, coupling hybrid technology with mid-rear architecture to cut fuel consumption and CO2 emissions on the combined cycle by fourty per cent whilst boosting performance.
The powertrain on display consists of 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 are connected to the 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 HY-KERS’ electric motor delivers power using one of the gearbox’s two clutches and is mated to one of the two main shafts. The result is instantaneous, continuous power delivery between the electric motor and petrol engine.
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 (power steering, brake servo, air conditioning, onboard systems).
Work on the system has now reached the end of the experimental phase and the development phase will commence in the coming months. With the same nominal power output of a normal ICE, the HY-KERS system will enable Ferrari to reduce emissions by fourty per cent over the combined cycle.
The engine concept will be used in the upcoming hypercar from Ferrari, the successor to the Enzo aka the Ferrari F70.
