The Chevrolet Astro II was designed in collaboration between GM Design and GM Research. What looks like a mixture between a Corvette Stingray and a GT40 is actually a prototype for a 1970s mid-engine Corvette. That’s right, the C8 might have been the first mid-engine Corvette going into production, but the idea has been around since the beginning.

The car had a welded steel backbone frame, a radiator mounted in the rear and a Mark IV big-block V8 engine driving the rear wheels via a 2-speed transaxle. The aft body section of the Chevrolet Astro II could be raised directly behind the passenger compartment to access engine and rear storage areas. The height of the vehicle was but a mere 43.7 inches (1110 mm).
