Despite its Italian roots, the Manta is Detroit-powered. Behind the passenger compartment is a 400 horsepower 5.4-liter Chevrolet V8 engine.
With the engine in the back rather than the front, designer Giugario decided to simply let the car's shape flow from its engineering. He didn't give the Manta a needlessly long hood or try to hide its long back end. Instead, the car's profile follows a clean, simple line up over the engine and the passenger compartment then down to the ground in front.
