17. Chrysler 300C SRT8

The Chrysler 300C SRT8 is the ultimate example of a luxury sleeper. While its exterior exudes executive class, the SRT8 packs a monstrous 6.1-liter Hemi V8 under the hood.
This powerhouse can rocket the 300C down the road faster than many classic muscle cars, all while coddling occupants in comfort. Autoblog hails it as a prime blend of refinement and raw performance.
