An efficient, new Audi clean diesel powertrain that achieved top honors at the Michelin Challenge Bibendum in Shanghai last week, is headed to the U.S. in 2008. The Challenge is an annual event, sponsored by the tire company, which promotes the development of sustainable transportation. To win in a category, a car is judged on several criteria including fuel consumption, emissions, driving safety, and handling characteristics. Audi’s new A5 TDI declared victory in the prototype vehicle class.

The A5 coupe is powered by the company’s latest 3.0-liter V6 diesel that utilizes a urea injection in its exhaust system. The after-treatment technology is designed to significantly reduce the oxides of nitrogen found in diesel emissions. A similar system has been implemented in Mercedes Benz’ upcoming Bluetec SUVs. The A5 finished first in the emissions category, and placed very high for fuel economy, managing 40.6 miles per gallon.

Though the A5 is still a prototype, its award-winning engineering is U.S.-bound and ready for production. The same diesel engine and low emission exhaust system will first be offered in the new 2008 A4 and Q7 TDI models. Other models are expected to follow. The powertrain, like Benz’s urea-based Bluetec system, will be available in all 50 states.
