The Chevrolet division of General Motors first used the name Impala for its 1956 General Motors Motorama concept car. The graceful African antelope was used as the car’s logo starting with this show car that incorporated Corvette-like design cues, especially in terms of the vehicle’s front grill. Notice the word grill is missing the ‘e’ at the end of the word. For some reason GM always left the ‘e’ off the end, ala BBQ grill, while other car companies use the more common and generally accepted spelling of grille replete with the ending ‘e’.
