TRAVERSE CITY, Mich. -- Volkswagen says it will offer a cleaner, more powerful and more fuel-efficient 2.0-liter turbocharged diesel engine in VW and Audi models beginning in about a year.
Oliver Schmidt, head of VW Group of America's Energy and Environmental Office, confirmed the new engine last week at the Advanced Powertrain Forum at the CAR Management Briefing Seminars.
The new engine will be rated at 150 hp -- 10 more than the current engine -- and have the same 236 pounds-feet of torque as the current version.
The change is expected to reduce production costs because the new engine is nearly identical to the diesels VW sells in other markets, Schmidt said. The North American version has a different emissions system geared to reduce oxides of nitrogen. The European version is tuned to reduce carbon dioxide.
"With the different emissions regulations, the engine sold in Europe could not be offered in the U.S. This made the engine expensive," Schmidt said about the outgoing diesel. "We did not want to do a specialized engine for the U.S. anymore. We wanted a base engine capable of meeting world standards with a scalable emissions system."
VW engineers designed an emissions system that packages the diesel particulate filter and selective catalytic reduction system in one assembly. The system injects urea into the exhaust to clean oxides of nitrogen from the exhaust.
The selective catalytic reduction system already is used in VW's large diesel vehicles, including the Passat and Touareg.
Schmidt said the new diesel will deliver better fuel economy than the current one, but didn't predict the specifics.
