Ferrari took the wraps off its new hybrid 599 HY-KERS at the 2010 Geneva Auto Show, and it’s as green as Ferrari can make it. Featuring a bit of traditional hybrid tech and a healthy dose of Formula1 witchcraft, Ferrari has manufactured a car that loses none of the dynamic performance of its gas-only brethren.
When it comes to center of gravity (CoG), lower is better. It is a concern in any car, but this concept is essential in a sporting car. By using clever packaging, the CoG of the HY-KERS is actually lower than a traditional 599. This clever packaging also keeps the hybrid equipment from infringing on any interior space.
As with most hybrids, the HY-KERS can run in full electric mode based on engine load and other factors. Unlike lesser hybrids, the HY-KERS does not feature a Continuously Variable Transmission. The electric motor mounts to the rear of a seven-speed dual clutch F1 transmission. Weighing about 88 pounds, the electric motor produces about 100hp to aid the not-anemic V-12. Hybrid battery charging is provided by using a Kinetic Energy Recovery System built on the experiences from last years Formula1 program.
FERRARI DEBUTS AT GENEVA WITH THE HY-KERS, A 'VETTURA LABORATORIO'
Geneva, 2 March 2010. Ferrari presents a vettura laboratorio (experimental vehicle) at the 80th edition of the Geneva Motor Show based on the 599 GTB Fiorano equipped with an advanced new hybrid transmission.
Hybrid technology is one of the solutions examined by Ferrari in its on-going research and development into making its production cars ever more efficient. Experimenting with alternative technologies represents the company's long-term strategy after the announcement in 2007 of a five-year plan to reduce fuel consumption and emissions across the range. With the launch of the Ferrari California (2008) and the 458 Italia (2009), in fact, Ferrari's average fuel consumption and CO2 emissions figures have already been reduced by around 30 per cent compared to 2007.
The HY-KERS displayed at the Geneva Motor Show is an example of how Ferrari is studying the application of hybrid technology to high-performance sports cars. Central to Ferrari's objectives is maintaining the balance, handling and performance characteristics typical of its cars despite the inevitable disadvantages in terms of weight represented by applying hybrid solutions to existing models.
To this end Ferrari 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 centre of gravity and ensuring that interior and luggage space are entirely unaffected. Similarly the flat lithium-ion batteries are positioned below the floorpan of the car inside the aerodynamic underbody. The result is a centre of gravity that is even lower than in the standard car. In addition, a part of the weight gained by fitting the electric motor, generator and the batteries is offset by being able to do away with the traditional starter motor and battery.
Ferrari has also applied its F1 technology to the design, engineering and construction of a new kind of electric motor which also helps optimise the longitudinal and lateral dynamics of the car, enhancing traction and brake balance. 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.
