Clean Diesel Volkswagen Jetta Makes North American Debut at Washington, D.C. Auto Show

Volkswagen 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 Volkswagen 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 Volkswagen 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 Volkswagen 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.
