With any of its three powertrains, the 2010 GL-Class is one of the best-performing plus-sized SUVs.

The least expensive version might be the best one: the newly renamed GL350 BlueTEC diesel. A 50-state-legal "clean" diesel, the 210-horsepower, 400-pound-feet BlueTEC 3.0-liter diesel gives the SUV quick acceleration with only a hint of throb and vibration-while it delivers fuel economy way up at 17/23 mpg, better on the highway than GM's full-size hybrid SUVs like the Escalade Hybrid. For $60,000, it's a little more expensive, but also has a cruising range of about 600 miles.

Next up in the performance range is the $62,000 GL450; its 4.7-liter V-8 guts out 335 hp and 13/17 mpg fuel economy, with little protest. For the creamiest power in the range, you'll have to go couch-surfing for spare change to acquire the $83,000 GL550, which speeds to 60 mph in about 7.4 seconds behind the power of a 382-hp, 5.5-liter V-8. With fuel economy of 12/17 mpg, you'll need to be very pleased with its rippling exhaust note-and you will be.

A seven-speed automatic is standard across the board, and it's nearly perfectly mated to the gas engines, though in past test drives we've noticed some shift shudder with the diesel GL-Class.

Handling is very well balanced in this full-size sport-utility vehicle. The air suspension is damped with ride comfort in mind, but the Mercedes-Benz GL still steers with precision and has strong brakes. A little less rocking motion side to side would improve on the good on- and off-road manners.

All GL-Class utes carry Mercedes' 4MATIC full-time four-wheel-drive system, Hill Start Assist, Hill Descent Control, and a load-leveling suspension system. We've crawled through some reasonably challenging mud pits in a first-year GL450, and found it capable enough for the kind of light off-roading most of us would encounter getting to a mountain hideaway or ski chalet. The GL450 can be ordered with an Off-Road package that includes a Class IV hitch, adaptive-damping suspension system, underbody skid plates, and locking differentials.

All models are capable of towing up to 7,500 pounds.

How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.
