Volvo Trucks North America's D11 and D13 engines have been certified by the U.S. Environmental Protection Agency and the California Air Resources Board as meeting upcoming 2010 diesel emissions standards.

Volvo says it's the first truck manufacturer to have its heavy-duty diesel engines certified for 2010 by both EPA and CARB, and that these engines have been fully certified to meet EPA's stringent standards without the use of emissions credits.

"EPA's certification of these engines is a crucial milestone in Volvo's journey to producing the cleanest diesel engines in the world," said Scott Kress, senior vice president - sales & marketing. "We are already building EPA'10 trucks and are fully on track for large-scale production next year, which will help make the air cleaner, use fuel more efficiently and save money for our customers."

All heavy-duty diesel truck engines produced after January 1, 2010 must meet the new standards. Volvo has extensive experience with selective catalytic reduction technology, having accumulated 5 million miles with 50 test vehicles in customer field test fleets in North America. Volvo also has billions of miles of real-world experience with SCR in other markets. The new SCR system was added to the proven Volvo engine platform, which has been used in North America since 2007 and was already well-known for its low emissions and high fuel economy.
