Mercedes Benz CLA

Before it dipped a petite toe in showrooms, the CLA was a can't-miss hit: a sexpot of a Mercedes for barely $30,000. The Benz mostly backs up the hype with a legit luxury interior and 208 horsepower from a 2.0-liter turbo 4. To blow minds and budgets, the AMg adds AWd and the most powerful 4-cylinder in series production ever: 355 ponies from a 2.0-liter twin turbo. [$30,825 (CLA250)/$48,375 (CLA45 AMG); mbusa.com]
