306 Horsepower

The newest car on this list is the 2015 Chevrolet Impala LT – but only with the optional 3.6-liter V6. That engine sends 306 horsepower to the rear wheels, routed through a six-speed automatic transmission. Like a few other cars we've selected, KBB values a good-condition Impala at just over $10,000. But if you’re willing to push that 85,000-mileage threshold a bit, the Impala is an affordable, rock-solid sedan with some oomph to boot.
