2011 Mercedes-Benz M Class - Review

Technically speaking, the M-Class is really the ML-Class, but we're not going to quibble. The 2011 Mercedes-Benz M-Class is the SUV that gave the brand a foothold in the American luxury SUV market, and it continues to be one of the most desirable. In fact, thanks in part to the stonking fast ML63 and the green-yet-fun diesel, MotorAuthority rates the M-Class a 9.

The M-Class is nearing the end of its current generation, with a new version on the way for 2012. Even with a newer, fresher face just around the corner, the 2011 M-Class isn't left looking out of place. It's sophisticated, attractive, and refined. Inside, the cabin feels expensive and looks it too, yet provides plenty of space for up to five adults and their luggage.

Performance varies widely from the base ML350 to the ML63 AMG, but even at the lower end, the ML350's V-6 is powerful and smooth. The ML350 BlueTEC diesel packs more torque and delivers better fuel economy, however, and is probably the smartest choice. For those that need a V-8 under the hood, there's the ML550, a strong performer. And for the truly mental--in all the right ways--SUV, the ML63 AMG delivers truly scalding performance and soothing luxury.

Competition from rival makes like BMW, Porsche, Infiniti, and even Volkswagen is heated, but the M-Class lineup is so varied it may have the broadest appeal of all.
