The HY-KERS vettura laboratorio (experimental
vehicle) a.k.a. Hybrid 599 GTB Fiorano is
an example that Ferrari is working on the
development of hybrid technology without losing
sight of performance..

In order to build this car, Ferrari has employed
its racing experience and adapted the advanced,
lightweight hybrid drivetrain to the 599 GTB
Fiorano with the aim of ensuring that vehicle
dynamics are unaffected. All the components were
integrated perfectly in the vehicle, even the lithiumion
batteries were positioned below the fl oorpan,
which means that the car has a center of gravity
that is even lower than in the standard car.
The F1 technology was used to build this vehicle,
which features a new kind of electric motor helping
it with the longitudinal and lateral dynamics.

The compact, tri-phase, high-voltage electric
motor of the HY-KERS system weighs about
40 kg and is mated to the rear of the dual-clutch
7-speed F1 transmission.
This means that it can operate through one of the
transmission’s two clutches and engages one of
the two gearbox primary shafts.
The new electric motor 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.
As you expected, the braking system also 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 per cent.
