Doubt it. It looks like it's missing an engine cradle based on how empty it looks behind the front wheels.
Also, production model should have reflectors in the rear based on patent images.
The proto is practically a production vehicle. Take a look behind the front wheels.
The scoop has always flowed back up to the top of the bumper. This just creates new vertical edges surrounding the top of the grille which makes it even more squared. Good work but the original has a nice flow.
The Supra's interior is disappointing. The steering wheel is one of the worse in the industry with that huge chunk of plastic as the lower spoke. That touchscreen design on any car always looks like an afterthought to me.
I prefer this Z's interior.
