"Not your father’s diesel car from yesteryears, today’s generation of clean diesel cars are fuel-efficient, quiet, low emission, and have the performance that makes them fun to drive!” says Tarry Shebesta, President of ACS.

One of the biggest advantages with these vehicles is their fuel efficiency. Overall the diesel versions get on average almost 10 mpg, or 30%, better mileage than their gas model siblings. The Audi A3 won the 2010 Green Car of the Year at the LA Auto Show with a 30 city / 42 highway rating, the same as the VW Jetta and Golf with whom it shares the same engine type.

There are also potential tax credits that make these a good option to consider. In addition to those offered from the IRS, BMW promotes a $4,500 “eco-credit” on both of its diesel models through March 1, 2010.

“Just like with hybrid vehicles, diesel technology is always changing. This makes leasing them a smart financial decision since owning out-dated technology can lead to poor resale values,” notes Shebesta.
