No one combines luxury with fuel-efficiency quite like Mercedes-Benz. Long a champion of the diesel cause, Mercedes continues that tradition in 2007, bringing a total of four luxurious diesel-powered vehicles to the United States.

The diesel-engined 2007 Mercedes-Benz E320 Bluetec took the top crown in both the Best Gas Mileage Luxury Sedan and Best Gas Mileage Diesel categories.
