The company said that it has employed its racing experience to adapt a lightweight hybrid drivetrain to the 599 GTB Fiorano with the aim of ensuring that vehicle dynamics are unaffected. This was achieved by the careful integration of all system components, positioning them below the center of gravity and ensuring that interior and luggage space are unaffected.
Similarly the flat lithium-ion batteries are positioned below the floorpan. The result is a centre of gravity that is even lower than in the standard car, the company added.
Ferrari has also applied its F1 technology to the design, engineering and construction of a new kind of electric motor which helps optimize the longitudinal and lateral dynamics of the car, enhancing traction and brake balance. The motor also features a cooling and lubrication system for efficiency under all operating temperatures and loads.
Weighing about 40 kg, the compact, tri-phase electric motor of the Hy-Kers is coupled to the rear of the dual-clutch 7-speed F1 transmission. It operates through one of the transmission’s two clutches and engages one of the two gearbox primary shafts. Thus power is coupled instantaneously between the electric motor and the V12, according to the company.
Under braking the electric drive unit acts as a generator, using the kinetic energy from the negative torque generated to recharge the batteries. According to Ferrari, this experimental vehicle reduces CO2 emissions on the ECE + EUDC combined cycle by 35%.
