Toyota and BMW are working together on a supercapacitor hybrid system
Toyota and BMW are to be working on a supercapacitor hybrid system together. The plug-in hybrid system would utilize similar technology to the Toyota's Le Mans LMP1 race car.
The use of supercapacitors will enable the system to quickly discharge energy to the motors in the car's hybrid four-wheel-drive system, while quickly recharging from regenerative braking.
It is not yet known what vehicles may receive this technology, but rumors point towards the BMW Z4 and the upcoming Toyota Supra.
