Engine and kinetic energy
The Special Limited Series will be powered by a development of the 740 CV 6.3-litre V12 introduced in the new F12berlinetta, along with the latest evolution of Ferrari’s HY-KERS electric hybrid system unveiled at the Geneva Show in 2010. The HY-KERS system is a performance enhancer, as well as a tool in the battle to lower emissions. In fact, it is estimated that that the system shaves 10 per cent off the car’s 0-200 km/h time, while cutting emissions by an impressive 40 per cent, while also enhancing a torque vectoring system, traction control and brake force distribution as it is fully integrated with Ferrari’s already phenomenal chassis electronics. Under braking, the KERS directs the kinetic energy to charge the batteries.
The choice of battery size and weight is a fundamental factor in this type of technology. The amount of electric power that can be used, and how it is used on a car with these characteristics, are decisions that are made with an eye to performance, given the car’s natural vocation. However, a balance must be struck between the requirement for a battery that is not too heavy and the need for the supply of sufficient energy required for electric propulsion. The electric motor/ancillaries/battery unit has a weight-to-power ratio of one, a figure in line with F1 in terms of efficiency, thus further improving the car’s overall weight-to-power ratio.
