2009 Mercedes-Benz M-Class Road Test Ratings

ML-Series SUVs handle well and can be fitted with a variety of stout engines. New this year is the 50-state Bluetec diesel, a very torquey engine that gets good fuel economy and runs as clean the cleanest gasoline versions. Inside, the MLs are ooze quality and luxury.

Strong engines produce significant power and torque. The new 50-state ML320 Bluetec turbodiesel is particularly stout, and it returns better fuel economy than the gasoline choices. Handling, braking and steering are quite good for an SUV of this size.

The ML feels quite luxurious inside. There is plenty of space up front, and the rear seat has even more room. The optional air suspension rides too soft, as some of our passengers felt queasy after riding on straight roads. The standard coil spring suspension might be a better choice.

Many aspects of the ML-Series are outstanding. There is a lot of cargo capacity and a sophisticated tie-down system keeps your stuff in place. There are a lot of clever features for the driver and passengers, too. But the COMAND system for the navigation and audio system is a headache to use, and the non-standard layout of a few other controls (shifter, cruise control) may be a problem if you other cars aren't Benzes, too.

The ML-Series SUVs are well-trimmed machines that give off a quaility look and feel. They cost more than the competition, but you do get more for that money.
