Piotr Czyzewski's Inferno 'Vario' concept car is to die for. The flared lines of the grille and front end remind me of a manta ray, and those clean, mean lines continue throughout the length of the car's body.

Although Piotr Czyzewski's Inferno 'Vario' car is just a design, I see great potential in its aerodynamic aesthetic. I'm hoping Ford or someone takes this design on and makes it happen. Check out some other sleek auto designs below.
