A brand-new model joined the Mercedes-Benz lineup for 2006. Dubbed a four-door coupe, two versions of the CLS-Class are available, including a high-performance, AMG-powered variant.

Beneath the hood of the CLS500 is a V-8 rated at 302 horsepower. Stepping up a notch, the CLS55 AMG features a 469-hp, supercharged 5.5-liter V-8. The CLS500 went on sale first, as an early 2006 model.

The CLS500 includes such features as Airmatic DC air suspension and four-zone climate control for comfort levels comparable to the automaker's S-Class sedan. Safety features include adaptive front airbags, side-impact airbags and side curtain-type airbags.
