Ferrari Experimental HY-KERS Hybrid Vehicle Vettura Laboratorio 2010

The HY-KERS vettura laboratorio (experimental vehicle) is an example of how Ferrari is approaching the development of hybrid technology without losing sight of the performance and driving involvement. This hybrid project is also aimed at ensuring that Ferrari will be in a position to comply with future CO2 emissions standards, particularly in term of the urban cycles.

Ferrari has employed its racing experience to adapt an advanced, 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 centre of gravity and ensuring that interior and luggage space are entirely unaffected. Similarly the flat lithium-ion batteries are positioned below the floorpan.

Ferrari has also applied its F1 KERS (kinetic energy recuperation system) technology to the design, engineering and construction of a new kind of electric motor which helps optimise the longitudinal and lateral dynamics of the car. The motor also features a unique cooling and lubrication system for optimum efficiency under all operating temperature and loads.

Weighing about 40 kg, the compact tri-phase high-voltage electric motor 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 seamlessly and instantaneously between the electric motor and the V12. The electric motors produces more than 100 hp as Ferrari’s goal was to offset every kilogram increase in weight by a gain of at least one hp.

While breaking the electric drive unit acts as a generator, using the kinetic energy from the negative torque generated to recharge the batteries. The phase is controlled by a dedicated electronic module. The module also manage the power supply and recharging the batteries and powers the engine’s ancillaries (power steering, power-assisted brakes, air conditioning, on-board systems) via a generator mounted on the V12 engine when running 100% under electric drive. It also incorporates the hybrid system’s cooling pump.
This experimental vehicle thus maintains the high performance characteristics while, at the same time, reducing CO2 emissions on the ECE+EUDC combined cycle by 35 percent.
