15. Cadillac CTS-V
For years, Cadillac was without a proper performance series to compete with BMW or Mercedes until the V-Series was born. It was all that Cadillac lovers dreamed of: Powerful engines, world-class handling, suspension setups and exclusive production. Even the competitors took notice when Cadillac rolled up with the new V-Series model.
The most successful was the second-generation CTS-V model they produced between 2008 and 2014. Under the hood was a supercharged 6.2-liter V8 with 556 HP, making the CTS-V the most powerful performance sedan on the market. The suspension and the rest of the drivetrain were advanced, so the CTS-V was the full package and one of the best cars available.
Cadillac produced three body styles, so the CTS-V came as a sedan, a coupe, and interestingly, as a wagon, too. With 556 HP LS9 V8 engine and 0 to 60 mph time of just 3.8 seconds, the second-generation CTS-V was one of the fastest four-door vehicles on the planet. The CTS-V was also a true muscle car sedan.
