The turbo doesn't have a back seat.

The 2+2 looks like it's sort of stretched out, and the fuel filler door is behind the rear wheel. The 2-seater has a more "natural" shape to its profile and the fuel door is in front of the rear wheel.

Not all 2-seaters are turbos. The way to tell a turbo is that is has 3 slats on either side of the main grille opening on the front bumper.
