Last week, Volkswagen of America introduced its cleanest diesel engine ever produced. It's a 2.0L four-cylinder TDI that will be available in Jetta sedan and wagon body styles in the summer of 2008 (as 2009 models) in all 50 U.S. states.

This innovative new engine meets the most stringent Tier II/Bin 5 standards without the use of urea injection. Instead, a nitrous oxide storage catalyst reduces NOx emissions by up to 90 percent. A particle filter further reduces emissions.

2009 Volkswagen Jetta TDI Volkswagen's 2.0L TDI uses 16 valves to generate 140 horsepower and 235 foot-pounds of torque. Featuring a common rail fuel supply system and high pressure injectors, smoothness and drivability have been greatly improved over previous Volkswagen diesel engines.

The benefits of using such a powertrain are aplenty. "Real world" fuel economy is said to be up by over 30 percent compared to an identical gasoline model. What's more, the new clean diesel TDI offers legendary durability and reliability without compromising the "fun to drive" factor.
