The car was redesigned for 1971, becoming longer, lower, wider, and with more rounded and aerodynamic styling featuring prominent bulges over the wheel arches, like the then-current Chevrolet Corvette. From this year, AMX became just the top-of-the-line model for the Javelin and other AMC car lines. The Javelin featured AMC's largest ever engine at 401 in³ as an option, although from 1972 increasing fuel consumption and emissions regulations cut performance. These Javelins competed successfully in Trans-Am racing in a Penske/Donohue team. Production ceased after the 1974 model year.
