With the lasting aroma and noise of diesel-powered vehicles from the seventies still in our memories, it will surprise many American drivers that today's generation of diesels are more affordable, cleaner running, and more fuel efficient than ever. Using Volkswagen's new clean diesel technology, the 2009 Jetta GTI Diesel Sportwagon satisfies EPA emissions standards for all 50 states.

Compared to the Toyota Camry Hybrid, which gets 33 mpg city and 34 mpg highway, the GTI gets 30 mpg city and 40 mpg highway. The cost of operation for the GTI depends on the price of diesel fuel, which varies from state to state. What does add up in the GTI's favor is its lower maintenance costs and its resale value. For example, a used 2006 GTI can sell for as much as it did when new.

Fuel prices and fuel efficiency considered, the new cleaner, highly efficient diesel engines today are able competitors for the more expensive and more costly to maintain gasoline-electric hybrids. Acceleration, braking and handling add to the driving enjoyment of the GTI. With tax credits for both the hybrid and the diesel, the GTI pulls ahead with its free scheduled maintenance for the first three years or 36,000 miles.
