Three Electric Motors
A four-wheel energy regeneration and drive system has been adopted which includes in-wheel motors in the front wheels in addition to one 150 kW rear-axle mounted electric motor. Thanks to this energy regeneration system with three motor/generators, the vehicle can more efficiently recover a greater amount of energy during rapid decleration and braking from high speeds.
Specially Designed Capacitor
In light of the fact that racing involves a repeated acceleration and deceleration under full system performance, a quick-charging capacitor system was adopted instead of the usual rechargeable batteries.
