2009 Mercedes-Benz Diesels
Mercedes-Benz is jumping full-tilt into the clean diesel game. Its three newest diesel models — the R320, ML320 and GL320 Bluetecs — will be sold exclusively in the United States starting this fall and will meet the toughest emissions rules in the country.
Powering the models is a diesel V-6 putting out 210 horsepower and a very healthy 400 pounds-feet of torque. Mileage estimates for the GL320 (which we'd assume would be the thirstiest of the three) is a combined 25 mpg.
The only bad news about these diesels is that they require an additive called AdBlue to keep emissions clean. And yes, the AdBlue needs to be refilled. However, Mercedes says the small tank only needs to be refilled at regular service intervals. If you already service your car at a dealership, that won't be any added headache. If you somehow miss a regular service, an alert will sound when your AdBlue level is low.
The 320 Bluetecs will all come standard with features like surround-sound audio and rear entertainment systems. All three will also feature a choice of three new infotainment systems with Bluetooth, HD radio and voice activation.
