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.

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.
