10 years of TDI – The history of the TDI

  • 1989 Audi presented the first diesel-powered passenger car with direct injection in the Audi 100. The 2.5-ltr. 5 cylinder TDI developed 88 kW (120 bhp) and 265 Nm of torque. A short while later, an 85 kW (115 bhp)  version conforming to the US standard valid at that time was launched. This engine was installed in over 20% of the Audi 100/A6 models.
  • 1991 saw the introduction of the four-cylinder 1.9-ltr. TDI developing 66 kW (90 bhp) and 202 Nm of torque in the Audi 80.
  • 1995 The performance-enhanced version of the 1.9-ltr. TDI developing 81 kW (115 bhp) and 235 Nm of torque came on the market. It was the first direct injection diesel to be equipped with a mapped exhaust gas  turbocharger with variable turbine geometry (VTG). The 103 kW (140 bhp) version of the 2.5-ltr. engine developing 290 Nm of torque was presented together with the permanent four-wheel drive quattro. This combination of two typical Audi technologies was to become a meteoric success.
  • 1997 Audi laid a yet another milestone with the V6 4-valve TDI. It was world’s first six-cylinder direct injection engine diesel to be used in a passenger car. It is also the most powerful of the production TDIs, developing 110 kW (150 bhp) and 310 Nm of torque.

Audi has revolutionised the popular conception of diesels with its TDI engines, proving that this engine concept can even compete with the petrol engine in terms of dynamics and driving enjoyment, with the added advantage of 30% lower fuel consumption and outstanding bottomend torque.

This engine therefore strikes a perfect balance between apparent opposites such as sporty driving on the one hand as well as eco-friendly mobility and long range on the other. Audi perfected these qualities, as exemplified by the five-cylinder TDI from 1989, with the V8 TDI Common Rail.
