Also known as the fifth generation "Shark", the 1973 Corvette debuted in the years of the first energy crisis. The 1973 differs among other Corvettes in combining a smooth body-colored nose with the original 1968-vintage "Kamm" tail. The front bumpers were always checked and updates were made to meet the new 5 mph standard, unfortunately the rear bumpers remained chrome. The new Corvette was improved with standard radial tires the first time on the Corvette, a more efficient Turbo Hydra-Matic automatic transmission option, and combined lap/shoulder belts.
