17. Cadillac ATS-V
Debuting in 2016, the newest American muscle four-door car is the compact but immensely powerful Cadillac ATS-V. With this model, Cadillac attacked the Mercedes C Class and BMW 3 Series with a modern executive sedan. The Cadillac ATS-V comes with recognizable styling and brutal power.
Under the hood is the twin-turbo 3.6-liter V6 engine with 464 HP and 445 lb-ft of torque. That’s enough to launch the ATS-V from 0 to 60 mph in just 3.7 seconds with top speeds of an astonishing 189 mph. Even though the ATS-V doesn’t have a V8, it’s still a proper muscle car and available in a two-door form as well.
