1978 AMC Gremlin GT
AMC tried to extract all it could from the Gremlin by constantly introducing different versions. They managed to keep that old platform alive for almost a decade. In 1977, AMC decided to turn the Gremlin into a muscle car. They installed a 304 V8 engine with 120 hp. The ridiculously low power resulted in terrible performance. However, the Gremlin GT had a fresh graphic package, sporty wheels, and updated interior equipment (via Top Speed).
Realizing the performance was painfully slow, AMC installed a 4.2-liter inline-six engine. It didn’t produce much more power, but it created more torque, enough for an improvement. Even more torque and heavy discounts didn’t help them. The production was low at around 3,000 copies. They discontinued the GT option for the 1978 model year.
