A recent BusinessWeek article shows more efficient diesel models still save you money at the pump. Even with $5 diesel & biodiesel prices, the diesel format is still the economical choice. See 10 models that prove it.
With the price of diesel fuel pushing $5 a gallon, many Americans might not think this is the best time to buy a diesel car or sport-utility vehicle. But they’d be mistaken. The fact of the matter is that even though the price of a gallon of diesel has climbed more than 55% in the past 12 months, diesel cars still offer better gas mileage—and savings—than regular cars. That’s because diesel engines are much more efficient than gas engines, delivering up to 25% to 30% more miles per gallon.
