Its been time-tested. The first passenger model was a 1936 Mercedes, so theres been decades of improvement to the technology.
Its the way of the future. J.D. Power and Associates predicts that the number of diesel vehicles purchased in the U.S. will double by 2012.
Its greener. Like the VW Touareg I drove, many run on low-sulfur clean diesel, which means its 98.5% cleaner than 1970s-era diesel cars. According to the EPA, if 33% of American drives switched to diesel, wed reduce our need for oil imports by 1.5 million barrels every day, or about 10% of our imported oil.
It goes farther. In Europe, diesel cars rule the road, since theyre known for getting far more miles per gallon than conventional gas, and also for having more durable engines.
It may be cheaper. Not only will you save money if you get more mpg, but Congress also offers $3,400 in tax incentives on diesel cars.
