HERNDON, VA - Audi's TDI clean diesel technology was a featured segment on the Discovery Communications program, "How It's Made," Sept. 18, with an encore broadcast on the Discovery Channel Thursday, Sept. 24 at 7:30 and 11:30 p.m. ET/PT.

The steps taken to assemble the Audi V-6 3.0 TDI clean diesel engine show a high level of detail, from block machining through final vehicle assembly. Audi launched its first TDI clean diesel model in the United States earlier this year with the Q7 SUV. Featuring 225 hp and 406 lb.-ft. of torque, the Q7 TDI has begun building awareness with American luxury car consumers that modern clean diesel technology is markedly improved in emissions, quietness, ride comfort, and overall performance. With a range of more than 600 highway miles per tank, the Q7 TDI employs 50-state clean diesel technology, which translates into 30-percent better fuel economy and a 20-percent reduction in greenhouse gas when compared to gasoline engines of similar size.

"American consumers are rapidly awakening to the advantages that TDI clean diesel technology can provide," said Johan de Nysschen, President, Audi of America. "TDI is a ready-now solution to American concerns about fuel consumption and emissions. Programs such as 'How It's Made' can only build greater awareness of clean diesel's modern practicality."

In late November, Audi will launch its second model featuring TDI clean diesel technology. The Audi A3 TDI offers the same sophistication, styling, operating efficiency and ride comfort that has distinguished Audi throughout its model range. Standard amenities include dual-zone climate control, leather seating surfaces, cargo nets behind the front seats, spit folding 40/60 rear seats and rear seat arm rest with dual cup holders.  Some distinctive options include Audi Navigation plus with RDS traffic, the expansive two-panel Panorama sunroof, and Bluetooth hands-free phone preparation.

The pulling power of torque is the signature performance feature in all diesel models, and the A3 TDI clean diesel is no different.  Offering 140 hp and 236 lb.-ft. of torque, this model performs briskly and efficiently with unmatched performance with its EPA-estimated 30/42 city/highway fuel efficiency.
