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