(November 19, 2012) Audi of America has announced the arrival of the new TDI clean diesel models for the Audi A8, A7, A6 and Q5 to debut at the Los Angeles Auto Show next week. The addition of these four models marks the first time Audi will feature a full lineup of TDI clean diesel vehicles in the U.S. as they join the updated Q7 model.

Each TDI vehicle delivers up to 30 percent better fuel economy and 30 percent lower carbon dioxide emissions than gasoline engines, resulting in longer range and fewer trips to the fuel pump. By having more density than gasoline, diesel packs more energy content in the same amount of fuel, which helps maximize the miles per gallon when that energy is released during a more powerful combustion cycle.

The TDI clean diesel engine lineup adds to Audi’s list of advanced technologies that help enhance fuel efficiency, including Audi ultra lightweight technology, such as the use of aluminum, and the AFS frame technology.

“Owners of Audi TDI engines have helped save over 4 million gallons of gasoline, or the equivalent of more than 240,000 barrels of foreign oil, since the introduction of Audi TDI to the U.S. in 2009,” said Scott Keogh, president, Audi of America. "And, TDI technology delivers better fuel efficiency without sacrificing performance.”

The A8 TDI will be available this spring. The other three nameplates will be available in the fall of 2013.
