AMC Javelin AMX (1974)
1974 was the last year for the legendary Javelin AMX, and despite all the effort from AMC’s engineers, the power output was down 20 hp to 235 hp from its optional 401 V8 engine (via Drives Today).
Even with all the performance goodies, sport suspension, and manual transmission, 0 to 60 mph times were just over eight seconds which isn’t fast, especially for a muscle car. The Javelin did enjoy some success on Trans Am circuits, but we are sure that it didn’t win many street races.
