The latest speculation from Toyota City concerning the Toyota Supra successor means that the flagship car may well be powered by a turbocharged 2.5-liter I-4 hybrid producing a minimum of 400 hp. Toyota may reveal the Supra production car late in 2017, though lets see an idea version once this year’s Tokyo Motor Show.

The recently signed agreement between BMW and Toyota will form the backbone to the improvement of the Supra successor, a coupe so one can be in response to the Toyota GT86 platform. One insider informs that the BMW Z4 successor will use a revised version of this platform, besides. While the Supra successor will incorporate a reinforced version of the GT86’s platform to deal with the additional horses, our source tells us that the body might be bigger than the GT86 and have a design inspired by the FT-HS hybrid concept car that debuted on the 2007 Detroit auto show. A rendering of what a future Toyota Supra successor is shown above; the Toyota FT-HS concept hybrid is pictured at right and below.

Unlike the Scion FR-S’ Subaru-derived boxer 2.0-liter I-4, our source indicates that essentially the mostsome of the most likely engine that allows you to finally end up propelling the brand new sports car can be a Toyota-built turbocharged 2.5-liter four-cylinder hybrid generating upwards of 400 hp. Nonetheless, a mid-mounted 3.5-liter V-6 hybrid remains a chance.

GT86 chief engineer Tetsuya Tada – who also happens to be the top of the Supra successor project – is operating to create an idea car for this year’s Tokyo Motor Show, a car with a planned debut of late 2017. As we noted in late November, Tada has admitted that Akio Toyoda has asked him to develop the auto “as soon as possible.”

We are told that BMW can help you with the suspension settings and handling of the hot Toyota. Meanwhile, our source also tells us that BMW, that will also use a beefed up version of the GT86 platform for its Z4 update, is testing a BMW-built V-6 hybrid unit that delivers similar power to the Supra successor.
