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