The limited production hybrid (only 499 units will be sold) LaFerrari that was unveiled at the Geneva Motor Show introduced the world to a hybrid system derived from Scuderia Ferrari’s F1 KERS technology. The current version of the HY_KERS that is available on the LaFerrari does not feature an electric only option even though the system is designed so that in future applications a car can be driven in electric mode only. The LaFerrari is the first Ferrari to utilize the benefits of the HY-KERS system. The gasoline engine in the LaFerrari is a 789 horsepower 6262cc V12 that revs to a maximum 9,250 rpm. The LaFerrari also features a 120 kw electric motor, giving the vehicle a combined power output of 950 horsepower.
The hybrid system is made of two electric motors developed in cooperation with Magneti Marelli. The first motor powers the driven wheels and the second the ancillaries. Developing the HY-KERS system in cooperation with Scuderia Ferrari allowed for considerable weight reduction pertaining to the individual components to include a battery pack that weighs 132 pounds. The batteries of the HY-KERS system are charged in different ways: the batteries will charge every time the V12 produces more torque than required such as what is achieved during cornering and every time under braking or even hard braking with the ABS active is achieved.
The LaFerrari’s Brembo braking system is also integrated into the hybrid system with several new features including new lightweight calipers designed to guarantee correct cooling and carbon-ceramic material discs. This has helped to allow the LaFerrari to put up track times 5 seconds faster than the Enzo and 3 seconds faster than the F12 Berlinetta.
