TDI history
1976 – Development of an extremely economic engine starts1989 – First turbodiesel with direct fuel injection
in a standard production car (Audi 100)
The reasons for the success story:Low fuel consumption
Driving pleasure
Good acoustics
In Europe the DI diesel engine has around a 50 %share of the passenger car market. Market forecasts worldwide indicate further growth.

This presentation contains forward-looking statements and information on the business development of the Audi Group. These statements may be spoken or written and can be recognized by terms such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “will” or words with similar meaning. These statements are based on assumptions relating to the development of the economies of individual countries, and in particular of the automotive industry, which we have made on the basis of the information available to us and which we consider to be realistic at the time of going to press. The estimates given involve a degree of risk, and the actual developments may differ from those forecast.
Consequently, any unexpected fall in demand or economic stagnation in our key sales markets, such as in Western Europe (and especially Germany) or in the USA or China, will have a corresponding impact on the development of our business. The same applies in the event of a significant shift in current exchange rates relative to the US dollar, sterling, yen, Brazilian real, Chinese rinminbi and Czech koruna.
If any of these or other risks occur, or if the assumptions underlying any of these statements prove incorrect, the actual results may significantly differ from those expressed or implied by such statements.
We do not update forward-looking statements retrospectively. Such statements are valid on the date of publication and can be superceded.
