Audi unveils new, clean and efficient 3.0 V6 diesel engine
At the ongoing 35th International Vienna Motor Symposium being held in Austria, Audi has introduced their latest generation 3.0 liter TDI engine in two states of tunes. Technology on board the engine sees auto emissions reduced to Euro VI levels while fuel consumption is stated to be lower by 13%.
Once ready for production, Audi will possess the most powerful single turbo 3 liter diesel engines in the premium class. Audi V6 diesel comes in with state of the art features to include piston rings and pins which will result in nominal friction. There is also separate coolant loops for crankcase and new cylinder heads besides the latest in thermal management, updated turbocharger and fully variable load oil pump.
With the new engine introduced by Audi, it is for the first time in automotive history that a Nox storage catalytic converter has been combined with a diesel particulate filter and SCR injection in a single assembly. This new engine complies with Euro VI standards with the existence of integrated exhaust gas after treatment with CO2 emissions averaging 15 gms lower than that offered by the earlier engine. It is estimated that the new engine will be seen on board the upcoming A4 and facelifted A6 range.
Power and efficiency: Audi presents new 3.0 TDI at Vienna Motor Symposium
New three-liter V6 as “clean diesel” and Euro 6 classification
Two versions with 160 kW (218 hp) and 200 kW (272 hp)
13 ultra models with extremely low fuel consumption in the Audi lineup
More powerful, more efficient and cleaner than ever: Audi presents the latest generation of its 3.0 TDI engine at the 35th International Vienna Motor Symposium May 8 and 9. The V6 diesel boasts innovative solutions in many 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 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 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 as much as 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 – as much as 13 percent more fuel efficient.
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. 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). This improvement earns the 3.0 TDI the “clean diesel” suffix.
The Audi lineup offers a broad choice of diesel engines with four, six and eight cylinders. It begins with the 1.6 TDI, includes the 2.0 TDI and 3.0 TDI, and tops out with the 4.2 TDI producing 283 kW (385 hp) and 850 Nm (626.9 lb?ft) of torque in the Audi A8 [7.4 l/100 km (31.8 US mpg), 194 g CO2 per km (312.2 g/mi)]. All of these engines combine ample power with groundbreaking efficiency, particularly in the 13 ultra models currently available. The Audi A4 1.6 TDI ultra, for example, consumes on average just 3.2 liters of fuel per 100 kilometres (73.5 US mpg) [85 grams CO2 per km (136.8 g/mi)]. These same figures for the A4 2.0 TDI ultra are 4.0 liters per 100 kilometres (58.8 US mpg) [104 grams CO2 per km (167.4 g/mi)] and for the A6 2.0 TDI ultra with S tronic 4.4 liters per 100 kilometres (53.5 US mpg) [114 grams CO2 per km (183.5 g/mi)].
Audi continues to honor a small tradition with the presentation of the new 3.0 TDI engine at the 35th International Vienna Motor Symposium taking place May 8 and 9 at the Congress Center Hofburg. The company presented its five?cylinder TFSI engine here in 2009 and in 2010 the (at that time) 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.” 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 extremely sporty, yet very comfortable. 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).
