Toyota Supra A80 design concepts
The first pic is a full-sized mockup from the Toyota studio in California. It reminds me of the Mitsubishi Eclipse but longer.
The following two were much more similar to the final A80, while the last two pics are just some vague clay models. The sides of the red design remind me of the Nissan 300ZX, and those rims make it even more clear.
