The new Audi V6 3.0l TDI engine

Audi has presented the latest generation of its V6 3.0l TDI engine at the 35th International Vienna Motor Symposium May 8 and 9. The V6 diesel boasts innovative solutions in several fields of technology.

As Prof. Rupert Stadler, Chairman of the Board of Management of AUDI AG, explains: “TDI engines are a central part of our technology mix for the mobility of tomorrow. We have continued to perfect this technology over several decades and believe there is still potential for increasing efficiency in the future too.”

“The new V6 3.0l 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. “We have led the competition ever since the first TDI engine 25 years ago, and are constantly extending this lead with new ideas.”

Audi offers the exhaust turbocharged V6 in two versions producing 160 kW (218 hp) and 200 kW (272 hp). It features a 90‑degree cylinder bank angle and a displacement of 2,967 cc. Peak torque is 600 Nm (442.5 lb-ft) depending on the model. Although the new 3.0 TDI is significantly more powerful than its predecessor, it is – again depending on the model – 13 percent more fuel efficient.src=”https://www.car-engineer.com/wp-content/uploads/2014/05/New-generation-of-the-Audi-V6-TDI-with-160-kW-218-hp-and-200-kW-272-hp.jpg” alt=”New generation of the Audi V6 TDI with 160 kW (218 hp) and 200 kW (272 hp)” title=” The Audi V6 engine features a 90‑degree cylinder bank angle, a displacement of 2,967 cc and peak torque is 600 Nm (442.5 lb-ft) depending on the model” height=”848″ width=”600″/>

The new V6 diesel is packed with several new 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 thermal management system improves efficiency. The turbocharger and the fully variable‑load oil pump have also been updated. 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 exhaust gas after‑treatment integrated into the engine package satisfies the most stringent of emissions legislation, including the Euro 6 standard. It also reduces CO2 emissions by an average of 15 grams (24.1 g/mi).

“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.” Besides the new 3.0 TDI, 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 sporty, yet comfort oriented. The newly developed dual-clutch transmission is reducing CO2 emissions by as much as 10 grams per kilometer (16.1 g/mi).

Romain’s opinion:

Looking at the pictures, there is a lot of components that seem to be new. What specific technology can you recognize on this engine (2 throttle valves, integrated crankcase ventilation system …)?
