Ferrari released details details of their first-ever hybrid vehicle based on the 599 GTB, which is a HY-KERS vettura laboratorio (experimental vehicle). The car features a lightweight hybrid drivetrain, consisting of a V12 petrol engine and a 100hp electric motor, and flat lithium-ion batteries which are fixed deep down in the car resulting in a lower center of gravity than the standard model.
The 599 HY-KERS also has a new kind of electric motor which also helps optimise the longitudinal and lateral dynamics of the car, enhancing traction and brake balance. Ferrari has used its formula1 know-how to develop this technology.
The motor cuts in during acceleration, providing instantaneous torque when moving away from a standstill and during overtaking manoeuvres, with torque control a function of grip, gear and accelerator pedal angle. Depending on vehicle speed and engine load – for example in town driving – the hybrid system can also function as a full-electric drivetrain. The result is a direct reduction in consumption and emissions. The motor also features a unique cooling and lubrication system for maximum efficiency under all operating temperatures and loads. The castings of the motor are made in the Ferrari foundry, complete with Prancing Horse motif.
high-voltage electric motor of the HY-KERS which weighs only 40 kg and develops 100 hp is coupled to a F1-style dual-clutch 7-speed F1 transmission. It also uses another Formula1-derived technology which is the KERS itself!
Under braking the electric drive unit acts as a generator, using the kinetic energy from the negative torque generated to recharge the batteries. This phase is controlled by a dedicated electronics module which was developed applying experience gained in F1 and, as well as managing the power supply and recharging the batteries, the module also 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 per cent under electric drive. It also incorporates the hybrid system’s cooling pump.
Ferrari has not yet announced any official performance and fuel consumption figures, but this being a Ferrari it won’t disappoint. Well, as far as it doesn’t compromise on power it’ll be alright!
