At the Vienna Motor Symposium that got underway on May 8 and 9, Audi presented an updated version of its 3.0-litre TDI V6 engine that is said to offer better efficiency and more power than the current version.
The new diesel engine will be offered in two states of tune. One that puts out 218PS of max power and one producing 272PS. Audi is not saying much when it comes to torque numbers but remarks, “depending on model” the unit could make as much as 600Nm. Besides, the German automaker claims that the new engine is up to 13 per cent more fuel efficient and produces 15 lesser grams of CO2/100 km.
To achieve the desired outcomes, Audi has packed the engine with new technology. It features low friction piston rings and pins and there are separate coolant loops for the crankcase. The cylinder heads also have been re-designed. The biggest change however, is that the NOx storage catalytic converter, diesel particulate filter and SCR injection system are combined into a single assembly, which Audi claims is an industry-first. The said updates have also made it possible for the engine to be Euro 6 compliant.
Commenting at the presentation, Prof. Rupert Stadler, chairman of the Board of Management of Audi AG said, “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.”
