2009 Mercedes-Benz GL320 BlueTEC First Impressions

Manchester, Vermont - Big, powerful, athletic... and now green. The new 2009 Mercedes-Benz GL320 benefits from the next-generation BlueTEC diesel technology. Thusly equipped, it offers a substantial reduction in fuel consumption and emissions while delivering the same outstanding performance.

BlueTEC is basically the only significant upgrade for the 2009 GL-Class. With an enviable position in the premium SUV/CUV segment, this M-B continues to pit itself against the Acura MDX, BMW X5 and the like -- only this time, it will be the cleanest of the bunch.

BlueTEC is basically the only significant upgrade for the 2009 GL-Class.

BlueTEC, a sustainable solution
The German automaker's BlueTEC technology was introduced in 2006 with the E320 CDI. That car went on to receive the crown of "2007 World Green Car of the Year".

The technology is now being applied to the GL-Class sport utility vehicle. Using all the latest filter systems out there, BlueTEC ups the ante by adding a urea-based fluid called AdBlue, which neutralizes nitrogen oxides to the extent that the GL320 now meets the stringent U.S. emission standards.

This environmentally-friendly system has little to no impact on performance and the driving experience. True, the vehicle feels a bit different and a tad noisier, like any diesel-powered SUV for that matter, but it certainly isn't unpleasant by any stretch.

Torque to spare
The 2009 Mercedes-Benz GL is remarkably explosive. While 210 ponies might not sound like a lot, the engine produces nearly 400 pounds-feet of torque at only 1,600 rpm. That's the beauty of diesels.

With so much low-end torque, the vehicle is never hesitant off the line, although a bit more juice, while not necessary, would have been appreciated. Fortunately, the torque curve remains strong at most engine speeds, which allows you to exploit the GL to the fullest. I have to admit that the 7-speed automatic transmission also does a wonderful job.

Accelerations from 0 to 100 km/h are completed in 9.5 seconds, while fuel consumption hovers around 11.5 liters per 100 kilometers in the city -- and considerably lower than that on highways and byroads.

Luxury and refinement
Inside, expect to find the same high levels of luxury as in other Mercedes-Benz products. Aside from the complicated ergonomics, particularly the ill-positioned gear selector (right above the left turn signal stalk in typical Mercedes fashion), occupants enjoy top-notch fit and finish as well as theater-like soundproofing.

Driving dynamics are not on par with the segment's top contenders (which has always been true about the GL), but the experience behind the wheel is definitely pleasant and comfortable.

Efficient, luxurious and high-performing, not to mention exclusive to North America, the 2009 GL320 BlueTEC will appeal to Earth-conscious buyers who see clean diesel as part of the solution to protect the environment. Other people, meanwhile, will barely realize that they're driving a diesel.
