8. BMW M6
Power: 560 Horsepower
The BMW M6 is a powerful automobile that boasts an aggressive design to complement the performance of the car. The 4.4 liter twin-turbo eight-cylinder engine is rated at 560 horsepower, and is combined with the choice between a seven-speed automatic or six-speed manual transmission when buying the car new. The M6 is considered significantly more agile than the BMW 6-series; however, the latest models still lack the expected feedback that one would enjoy with a traditional sports car.
