Toyota Hybrid Race Car Wins Tokachi 24-Hour Race; In-Wheel Motors and Supercapacitors
17 July 2007

The car, which is based on the Supra GT used in Super GT races in Japan, uses a four-wheel energy regeneration and drive system which includes 10 kW in-wheel motors in the front wheels in addition to one 150 kW rear-axle mounted electric motor.
A quick-charging supercapacitor system provides energy storage for the vehicle.
The car completed 616 laps in the 24 hours—19 more than the second place finisher.
In 2006, Toyota was the first car manufacturer to enter a hybrid vehicle into the Tokachi 24-Hour race—a Lexus GS450h which finished 17th overall. By entering hybrid systems into racing events, Toyota engineers hope to discover ways to make hybrid systems more efficient and lighter.
