The Environmental Protection Agency (EPA) is expanding its VW diesel investigation to include the automaker’s 3.0-liter V6 diesel engine.
The engine is used in various Audi models and the Porsche Cayenne, which means the Volkswagen Group could be facing an even larger fine than the maximum $18 billion currently expected. The models that are affected by the VW diesel scandal currently include the 2009-2015 Audi A3, 2009-2015 Volkswagen Jetta and Jetta SportWagen, 2009-2015 Volkswagen Beetle and Beetle Convertible, 2009-2015 Volkswagen Golf, 2014-2015 Volkswagen Passat and the 2015 Volkswagen Golf SportWagen.
In the Porsche Cayenne diesel, the 3.0-liter V6 engine makes 240 horsepower and is rated at 20 mpg in the city and 29 mpg on the highway. The updated engine was revealed last year and in Audi models has either 218 hp or 272 hp with a maximum torque output of 442.5 pound-feet.
“The new 3.0 TDI substantiates our claim as the leader in diesel technology,” said Prof. Dr. Ulrich Hackenberg, Member of the Board of Management of Audi AG, technical development when the engine was revealed. “We have led the competition ever since the first TDI engine 25 years ago, and are constantly extending this lead with new ideas.”
