Chrysler Group's go-anywhere brand will answer these petitions early next year when it begins selling Jeep Grand Cherokees in North America outfitted with a highly regarded 3.0-liter diesel engine currently used in Europe.

The oil-burner will be paired with Chrysler's Torqueflite 8-speed automatic transmission. Though I don't know where the mileage rating will come in, I suspect the combination will give Jeep's luxury SUV an mpg comparable to a full-sized sedan.
