Audi introduced the latest generation of its 3.0 TDI engine at the 35th International Vienna Motor Symposium, held May 8 and 9.
The German automaker said the new V6 diesel boasts innovative solutions in many fields of technology.
“TDI engines are a central part of our technology mix for the mobility of tomorrow,” said As Prof. Rupert Stadler, Chairman of the Board of Management of AUDI AG. “We have continued to perfect this technology over several decades and believe there is still potential for increasingy efficiency in the future too.”
Audi explained it offers the exhaust turbocharged V6 in two versions: 218 and 272 horsepower. It features a 90 degree cylinder bank angle and a displacement of 2,967 cc. Peak torque goes up to 442.5 pound-feet depending on the model. Although the new 3.0 TDI is significantly more powerful than its predecessor, it is, according to Audi and depending on the model, up to 13 percent more fuel-efficient.
The four rings brand said the new V6 diesel is packed with numerous high-end features. The piston rings and pins have been optimized for minimal friction. The crankcase and the newly designed cylinder heads have separate coolant loops. The updated, innovative thermal management system improves efficiency even further. The turbocharger and the fully variable load oil pump have also been updated.
Per Audi, for the first time in automotive history, a NOx storage catalytic converter has been combined with a diesel particulate filter and SCR injection in a single assembly.
The presentation of the new 3.0 TDI engine at the 35th International Vienna Motor Symposium taking place the Congress Center Hofburg is becoming a tradition for Audi. The company presented its five-cylinder TFSI engine there in 2009 and in 2010 the then new 3.0 TDI. The premieres of the 3.0 TDI biturbo and the new 1.8 TFSI followed in 2011. Audi presented the 4.0 TFSI in 2012, and the company first presented the V6 TDI for the Audi R18 e-tron quattro race car to the public at the 2013 Vienna Motor Symposium.
“The Vienna Motor Symposium offers us an excellent stage for our technologies,” said Dr. Stefan Knirsch, Head of Engine Development. “We can present our innovations and discuss them here with experts from all around the world.”
Audi is also presenting another innovation in Vienna: a new seven-speed dual-clutch transmission for models with longitudinal engines and front-wheel drive. The latest-generation S tronic is extremely sporty, yet very comfortable. Audi stated the newly developed dual-clutch transmission impresses with its high efficiency, reducing CO2 emissions by as much as 10 grams per kilometer (16.1 g/mi).
