3. Pontiac GTO (2004-2006)
When Pontiac revived the GTO in the early 2000s, they gave it an unexpected heart transplant: the Corvette LS1 V8 engine.
This powerhouse engine, renowned for its performance in the C5 Corvette, transformed the GTO from a humble coupe into a true muscle car with supercar-level power.
With its thunderous acceleration and torque, the GTO gave drivers a taste of Corvette performance in a more affordable and understated package.
