A project to build a Toyota GT86 hybrid is “quite advanced now,” according to Koei Saga (Toyota’s senior manager for drivetrain engineering) in an interview with Autocar. He said that if he receives the green light, his team will be ready to do it. Saga suggested that the hybrid GT86's drivetrain may utilize a combination of existing systems that have already been seen on road and track.
They already have a hybrid system that can be used for this type of vehicle, fitted with the production passenger car hybrid system. It also uses the pure race-oriented hybrid system [in the TS030 LMP1 racer and Prius GT300 from Japan's Super GT series].
Even when front-drive is used on all Toyota-branded passenger cars, Lexus uses the same basic Hybrid Synergy Drive technology in its hybrids, such as the rear-drive-only GS 450h.
The electric motors can be used in starkly contrasting conditions due to the system’s modular nature. The single electric motor used in the Yaris Hybrid has also been installed in the four-wheel drive Yaris Hybrid-R concept racer recently introduced. It is applied together with different engine types but so far, it hasn’t appeared in a boxer such as the existing GT86's 197bhp four-pot.
A CVT gearbox is used by Toyota's passenger car applications while the Yaris Hybrid-R is equipped with a six-speed sequential transmission. To maintain its attractiveness to drivers, the hybrid Toyota GT86 would have to keep a manual gearbox. Saga also said that the Toyota hybrid sports car will have a good layout design so even if it’s heavier, it can still be “a fun car to drive."
