Yesterday at the Washington Auto Show, Volkswagen officially unveiled its cleanest diesel ever, which will be found in the next Jetta TDI. As we told you about earlier this month, the new diesel Jetta is powered the 2.0L BLUETEC diesel four-cylinder, which will meet emissions standards in all 50 states without the use of urea injection.

Instead, the new TDI uses a nitrogen oxide storage catalyst, which reduces NOx emissions by up to 90 percent. The engine management system in the Jetta changes operating modes periodically to treat the NOx that has been stored in the catalytic converter. A particulate filter in the exhaust system further reduces emissions.

Volkswagen didn’t release any detailed information like power, pricing or fuel economy numbers. But the new clean diesel Jetta will be available in the U.S. market in the spring of 2008.

Full press release after the jump.

CLEAN DIESEL VOLKSWAGEN JETTA MAKES NORTH AMERICAN DEBUT AT WASHINGTON, D.C. AUTO SHOW

WASHINGTON, D.C. – Volkswagen of America, Inc. today unveiled its cleanest diesel ever for the U.S., the Jetta TDI. Additionally, the company announced that this new clean diesel will be available to the U.S. market in the spring of 2008. This Jetta TDI will meet emissions standards applicable in all 50 states, including the most stringent “TIER 2/BIN 5” or “LEV II/LEV” requirement limiting nitrogen oxide (NOx) emissions to 0.05 g/mile.

This clean diesel Jetta meets the lowest emissions standards without the use of urea injection. Instead, a nitrogen oxide storage catalyst reduces NOx emissions by up to 90 percent. The engine management system in the Jetta changes operating modes periodically to treat the NOx that has been stored in the catalytic converter. A particulate filter in the exhaust system further reduces emissions.

The Jetta TDI is one of the first products of the BLUETEC offensive initiated jointly by Audi, Mercedes-Benz, and Volkswagen. The goal of this partnership is to establish the concept of BLUETEC as a uniform label for clean and highly fuel efficient diesel-powered cars and SUVs with 50-state compliant engines. BLUETEC denotes diesel power plants that comply with the strictest emissions regulations of the US market. The technologies individually developed by each manufacturer serve to reduce NOx in particular – an exhaust element more prevalent in a diesel engine.

Volkswagen unveiled its clean diesel concept Tiguan compact SUV at the Los Angeles Auto Show in November. The Tiguan will be available in the U.S. mid 2008.

Volkswagen has a 30-year history of providing the U.S. market with efficient and durable diesel vehicles. Diesels traditionally account for almost 20 percent of Volkswagen’s sales in the United States.

Founded in 1955, Volkswagen of America, Inc. is headquartered in Auburn Hills, Michigan. It is a subsidiary of Volkswagen AG, headquartered in Wolfsburg, Germany. Volkswagen is one of the world’s largest producers of passenger cars and Europe’s largest automaker. Volkswagen sells the Rabbit, New Beetle, New Beetle convertible, GTI, Jetta, GLI, Passat, Passat wagon, Eos, and Touareg through approximately 600 independent U.S. dealers.
