If you'd like to commute in a diesel but don't want to drive a giant truck or a clapped-out, old oil-burner, there are lots of choices for new diesel vehicles that offer terrific fuel economy. Even more diesel vehicles will be on the way later this year, but here's a list of the diesels with mpg ratings by the EPA that should be on dealer lots by the time you read this.
The '07 Jeep Grand Cherokee will be available with the same engine found in the E320 Bluetec.

MPG Testing
Fuel economy is measured under controlled conditions in a laboratory using a standardized test procedure specified by federal law. Manufacturers test their own vehicles-usually preproduction prototypes-and report the results to the EPA. The EPA reviews the results and confirms about 10-15 percent of them through its own tests at the National Vehicles and Fuel Emissions Laboratory.
The EPA fuel-economy tests use driving routines, or schedules, performed in the laboratory. For '07-and-earlier model year vehicles, two test schedules are used:
City: It represents urban driving in which a vehicle is started with the engine cold and driven in stop-and-go, rush-hour traffic. The driving cycle for the test includes idling, and the vehicle averages about 20 mph.
Highway: It represents a mixture of rural and interstate highway driving with a warmed-up engine, typical of longer trips in free-flowing traffic. Average test speed is about 48 mph and includes no intermediate stops or idling.
