Audi has unveiled its next-generation V6 3.0 litre TDI turbocharged diesel engine at the International Vienna Motor Symposium this week, offered with two power outputs.

The 90-degree V6 can soon be had in various Audi products with either 160kW or 200kW; up from 150kW and 180kW from the current generation 3.0 litre diesel engine.

Torque rounds out at 600Nm for the 200kW unit, and Audi says the new engine is up to 13 percent more fuel efficient than its predecessor, although official fuel figures are yet to be made available.

The new engine gets a NOx storage catalytic converter with a diesel particulate filter and selective catalytic reduction (SCR) injection, which Audi says is the first time these technologies have been combined in the one assembly.

An integrated exhaust-emission treatment system helps the new engine meet Euro Six emission standards, with a CO2 output around 15 grams lower on average than the unit it replaces.

Other features for the new 3.0 litre V6 diesel include redesigned cylinder heads, an updated turbocharger and oil pump, improved thermal management system including separate coolant loops for the crankcase and low-friction piston rings.

“The new 3.0 TDI substantiates our claim as the leader in diesel technology,” Audi’s Professor Dr Ulrich Hackenberg said.

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

Audi has also used the symposium to showcase a new seven-speed dual-clutch S-tronic transmission, which can reduce CO2 emission by up to 10 grams per kilometre.

The new transmission is for models with longitudinal engines and front-wheel-drive, described by Audi as “extremely sporty, yet very comfortable”.
