At Audi, Vorsprung durch Technik is not simply our advertising slogan. Its at the heart of everything we do. By using technology intelligently, we can create cars that are genuinely progressive. One of the ways we measure progress in today's car is how efficiently it uses fuel, which is why new engine technology is at the forefront of so much of our work. Every year we take part in Le Mans 24 hour endurance race. But for us, it isn't simply about coming first. It's an essential part of the development of highly efficient fuel-injection systems. Our new TDI engines are a direct result of this. And among the most frugal we've ever made. Take the Audi A4 2.0 TDIe, for example. At 120g/km of CO2, its one of the lowest A4 ever. or the new Audi A3 1.6TDI. At just 109g/km, its one of the lowest in its class. Or the Audi TT TDI which can do 53.3mpg or 600 miles on a single tank. Even the current Audi A6 is up to 17% more fuel efficient than its predecessor. We've made fuel efficiencies in performance models too. The new S4 has a supercharged engine, but 2 cylinders fewer. The result is not only 97g/km improvement in CO2 emissions but also a 0.5 second improvement on 0-60mph. of course with every innovation comes the challenge to create new ones. And that what we'll continue to do. For as long as we put Vorsprung durch Technik on our adverts in fact. Official fuel consumption figures for the A3, A4, TT, A6 and S4 range in mpg (l/100km): from urban 19.1 (14.8 - 56.5 (5.0), extra urban 36.2 (7.8) - 76.3 (3.7), combined 27.2 (10.4) - 68.9 (4.1), CO2 emissions from 109 - 250g/km.
