Hybrid vehicles with two power train use a bidirectional energy source to recover some of the kinetic energy that can be lost when the vehicle slows down. In the context of racing vehicles, parallel hybrids with the KERS system are more often used, which effectively manages the recovery of both kinetic and thermal energy. The FDR Moscow team analyzed the characteristics of the Ligier JS 53 evo2, which set a record on the highway in Sochi (Russia). To create a fast ring vehicle, the parameters were observed in terms of weight (minimum 690 kg, including pilot and fuel) and power (maximum 280 hp with the possibility of increasing). A study of the effects of mass and power revealed that approximately 6.5 hp must be added to compensate for every 10 kg. To achieve equal lap time with the vehicle on the internal combustion engine, the mass of the combined power plant should not exceed 66.5 kg with a power above 43.2 hp. Simulations conducted at Silverstone National have shown that reducing weight and optimizing energy use strategies can significantly improve the competitiveness of a hybrid vehicle. As a result, efficient regenerative braking and stored energy management play a key role in improving the performance of hybrid systems.
