The General Motors designed car was a radical departure from cars of its era and sported a 250 HP V8 Rocket engine among other things. In the late fifties, Harley Earl, Bill Mitchell, Ken Pickering and Zora Duntov were creating a roadster for Oldsmobile. They began the project by designing several showcars which were breathtaking and daring, especially compared to the Oldmobile aesthetic. Due to the poor sales of the Corvette, the car which inspired these GM Concepts, the F-88 project was cancelled at the conceptual phase. Before that time however, four very unique Oldsmobiles were completed and a recent auction of a surviving car fetched $3.5 million.
