Audi claims that the TDI burns 35 percent less fuel than gasoline counterparts, which reduces CO2 emissions accordingly. At the "German TecDay," an information event organised jointly by Volkswagen, Bosch and the Association of the German Automotive Industry in San Francisco, California, Ralf Weyler from Audi Marketing said: "No other drive system can beat the TDI's combination of high power and low fuel consumption."
According to EPA estimates referenced by Audi, the US could save 1.4 million barrels of oil per day if one third of passenger vehicles and light duty trucks used modern diesel engines. A report by J. D. Power forecasts a 12 to 15 percent of share market for diesel vehicles in 2015.
The engine has impressive figures: 240 HP, 550 Nm of torque (406 lb/ft) obtained from an array of technical features such as common rail injection, monitors that control the combustion chambers and an emission system that uses carbonic acid diamide solution ("urea"). The engine fulfills the LEV Tier II Bin 5 emission standards (operatiing in states such as California, Massachusetts, New York, Maine and Vermont) and the new emission limits that will come into force in Europe in 2014.

The TDI engine is the most successful efficiency technology in existence; Audi first introduced it into series production 18 years ago and has been progressively extending its lead over rival technologies ever since. "The TDI units burn up to 35 percent less fuel than the average of petrol engines typically used in the USA. This means that the TDI can assume an important role in the rapid reduction of CO2 emissions," comments Ralph Weyler, Board Member for Marketing and Sales at AUDI AG. At the "German TecDay", an information event organised jointly by Volkswagen, Bosch and the Association of the German Automotive Industry in San Francisco, California, Weyler emphasised: "No other drive system can beat the TDI's combination of high power and low fuel consumption."
According to calculations by the Environmental Protection Agency (EPA), the United States could save 1.4 million barrels of crude oil every day if just one third of all passenger cars and light-duty commercial vehicles were equipped with up-to-date diesel engines.
Leading market research firms such as J. D. Power predict that diesel engines will have a 12 to 15 percent share of the US market in 2015, which represents a substantial jump compared to the current share of sales of around four percent.
The new Audi 3.0 TDI with ultra-low emission system develops an output of 176 kW (240 bhp) and 550 Nm of torque, making it both powerful and efficient. New technologies optimise the combustion process in the V6: the common-rail injection system builds up 2000 bar of pressure, while sensors monitor the combustion chambers. One crucial innovation is the ultra-low emission system in the exhaust tract, which largely eliminates nitrogen oxides by means of a carbonic acid diamide solution. With this system on board, the 3.0 TDI fulfils the toughest emission standard in the world – the LEV II Bin 5 classification, which is operative in the US states of California, New York, Massachusetts, Maine and Vermont. The high-tech diesel from Audi also already complies with the emissions limits that are due to come into force in Europe from 2014.
Audi is tackling the issue of efficiency with all its resources – with new technologies, new engines and new drive concepts. A host of other forward-looking solutions are available besides the cleanest diesel engine in the world. These include the groundbreaking, ultra-efficient FSI engines with petrol direct injection, as well as technology modules for Intelligent Energy Management (IEM), such as a start/stop system and a micro-hybrid. In view of the fact that the fuels themselves have a key role to play in the reduction of CO2 emissions, Audi is also focusing its attention on the second generation of biofuels which use the entire plant rather than just its fruits.
Whatever new development it is working on, the brand with the four rings stays true to one clearly defined precept: Audi seeks to heighten the efficiency of all its new models, whilst at the same time further enhancing their sporty profile and the driving pleasure they offer.
