Introduced in 1968, the Porsche 908 was created as Stuttgart’s more-focused shot at competition success in the FIA’s Group 6 Prototype-Sports Cars class. The car is simple and completely stripped of any fluff whatsoever. Outside, the 908 gets a short, flat body made from fiberglass (both coupe and spyder variants were created), as well as simplified aerodynamics. The driver sits very far forward, his or her feet hanging ahead of the front axle to make room for the 3.0-liter flat-eight engine. With as much as 350 horses on tap, the 1,100-pound 908 was basically like a big racing kart, beating its heavier, more powerful competition on the twisty, more narrow tracks of the sports car series.
