Powertrain, Steering, Brakes, Dimensions, & Suspension

From its inception in 1953, the Chevy Corvette has always been recognized as a vehicle that was a “step above the common car. Beginning with its earliest Motorama concept, to its first production models and beyond, the Corvette quickly became recognized and universally accepted as “America’s sports car” and, over time, became increasingly synonymous with the American dream – a dream in which every American could aspire to own a house, have 2.5 kids, and afford a sporty, two-seat, convertible coupe.
