New details have emerged about the highly anticipated hybrid sportscar co-developed by BMW and Toyota.

It will adopt a front-engined, all-wheel drive layout with a supercapacitor hybrid system derived from Toyota's Le Mans LMP1 racer. The Japanese marque seems to be in charge of the all-new plug-in hybrid system which will feature supercapacitors to store kinetic energy for a short period of time in order to grant the vehicle with a performance boost.

The reason why both automakers opted for supercapacitors is related to their capacity to absorb and discharge kinetic energy quicker than lithium-ion batteries. In addition, these are also lighter and smaller and will be implemented in a body engineered by BMW.

Power will likely come from a BMW-developed 4-cylinder, 2.0-liter gasoline engine working together with electric motors produced by the Bavarian marque to the specs supplied by Toyota. A sequential manual gearbox is planned while the electronics system is going to be developed by Toyota and should offer torque-vectoring capabilities.

Expect to find an aluminum and high-strength steel floorpan combined with carbon fiber applications in the non-load-bearing areas. For the outer body BMW will likely utilize CFRP panels while both cars will have different exterior and interior designs.

BMW's version will be a replacement of the Z4 whereas its Japanese cousin will serve as a spiritual successor of the Supra. Both of them are rumored to come out sometime in 2017.
