Audi has unveiled its latest generation of 3.0-litre V6 TDI engine boasting of innovative technologies at the recently concluded 35th International Vienna Motor Symposium. The exhaust turbocharged V6 diesel engine features a 90-degree cylinder back angle and will be available in two versions, one producing 218 hp and another pumping out 272 hp. While Audi has told that the peak torque is 600 Nm depending on the model, it hasn’t revealed which version will get it. The company has also told the engine is 13% more efficient, again depending on the model.
In comparison, the current 3.0-litre TDI engine that are featured in Audi A4, A6 and A7 models in India produces a maximum power of 241 hp and peak torque of 500 Nm.
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 increasingy efficiency in the future too."
"The new 3.0 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’s new 3.0 V6 diesel engine is comes loaded with latest and innovative technologies. The piston rings and pins have been optimized for minimal friction. The crankcase and the newly designed cylinder heads have separate coolant loops. To improve efficiency, the thermal management system has been updated. So have been the turbocharger and the fully variable-load oil pump. And 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. This improvement earns the 3.0 TDI the "clean diesel" suffix.
Apart from the new 3.0 TDI, Audi also presented a new seven-speed dual-clutch transmission. The new S tronic transmission is designed for models with longitudinal engines and front-wheel drive. While being extremely sporty, the new dual-clutch transmission is very comfortable to use and scores with its high efficiency. It also helps in reducing CO2 emissions by as much as 10 grams per kilometer.
