Muscle cars are renowned for their powerful V8 engines and the roar that turns heads. However, not all models stayed true to this legacy. Some iconic muscle cars were released with engines that seemed out of place. Let’s take a look at 10 muscle cars that sported unexpected engine choices.

Ford Mustang II with the 2.3L Inline-4

The Ford Mustang II was introduced during a time of stringent emissions regulations and fuel crises. It came with a 2.3L inline-4 engine, a far cry from the powerful V8s that the Mustang was known for. While it offered better fuel efficiency, it lacked the power and performance that muscle car enthusiasts craved.

Chevrolet Camaro Berlinetta with the 2.8L V6

The Chevrolet Camaro Berlinetta of the early 1980s was marketed as a luxury variant. It featured a 2.8L V6 engine, focusing more on comfort than performance.

Dodge Challenger with the 2.2L Turbo I4

The Dodge Challenger was known for its aggressive styling and powerful engines. However, the 1980s saw a shift with the introduction of a 2.2L Turbo I4 engine. While the turbo added some excitement, it still fell short of delivering the muscle that the Challenger name implied.

Mercury Cougar with the 3.8L V6
