TDI history

1976 – Development of an extremely economic engine starts 1989 – 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.
