Audi North Dublin

The TDI® engines in the Audi A4 Saloon.Powerful and efficient.

The TDI engines are provided with the common rail injection technology and a diesel particulate filter; the 3.0 TDI engine is also available as a clean diesel version. As standard, all engines are equipped with the start-stop system and recuperation, as a result of which they are among the most fuel-efficient power units of their class.

One in every two Audi cars sold today is a diesel. What we take for granted now was quite a sensation a mere 20 years ago: Audi revolutionised the market with the first 2.5 litre TDI engine. Since then, developments such as common rail technology with its refined and precise fuel distribution have made TDI even more efficient. Consequently, since the first TDI, the engines have become more economical, whilst specific output has increased. So it was only logical that a diesel car should then enter the world of motorsport. And successfully too: in 2006, Audi was the first car maker to win the Le Mans 24 Hours with a diesel-powered race car, the Audi R10 TDI – and then went on to repeat this victory several times over, most recently in 2011.
