Mercedes Benz

The 2011 SLK line includes two distinct V6-powered models - the SLK300, with a 228-horsepower 3.0-liter V6; and the SLK350, which features a 300-hp version of the popular 3.5-liter V6. For 2011, both models come with standard Sport body styling that includes deeper front and rear aprons as well as lower door sills. Black inlays around the headlights have also been added. The SLK hardtop sets it apart from the competition. With the top up, it's a quiet coupe - push a button, and the car goes topless. The SLK roof goes up or down in 22 seconds, and the folded roof takes up surprisingly little trunk space - thanks to its pivoting rear window.
