The 2009 Mercedes-Benz ML320 looks nearly identical to the ML350 and ML550, but is totally different to drive, mostly because the ML320 is a clean-burning diesel. Maybe it’s like dating twins, although I’ve never done it so I can’t say for sure. If you have, let me know if I’m totally off-base (I promise not to judge you).

This diesel is touchy and uppity. It takes some time to figure out how to finesse it because it’s pretty hyper. I was snapping everyone’s heads around for a day or so until I got used to it. Technically it’s called torque, but I call it herky-jerky. Whatever you call it, it required me to make some adjustments to the way I drove. The smaller diesel engine is quite powerful. On paper, it has much less horsepower than the other models, but I never felt that it was lacking. The EPA-estimated 18/24 mpg city/highway is much better than the ML550’s 13/18 mpg with its gas-guzzling V-8. Am I worried about getting stuck out in the world without a nearby gas station that has diesel fuel? Nope: Mercedes’ Comand information and entertainment system instantly finds gas stations with diesel for me. It’s a nice touch for those of us who can be paranoid about that sort of thing.

The ML320’s BlueTec system makes this diesel vehicle emissions-compliant in all 50 states. This is achieved with a urea additive, AdBlue, that mixes with exhaust fumes and reduces the car’s emissions. Click here to learn more about BlueTec. The engine is pretty quiet, but it still has that diesel sort of growl that’s loudest when idling.
