What is the common feature of the racing vehicle and the police vehicle? Both should be fast, and for both it was unthinkable that one day a diesel engine would be used. Admittedly, for very fast, short distances, the diesel is not yet competitive, but especially for longer distances with gas stops, the diesel has its chance, even if the track includes a high percentage of full load. Indeed, the consumption advantage of the diesel shrinks considerably, because the old rule-of-thumb still holds true: With full load all internal combustion engines consume roughly the same.
BMW has contributed to the success of the diesel engine, even if they entered the dieselmarket only in 1983, relatively late. Before, the diesel engine was disqualified as slow and lame, consequently unsuitable for a BMW. In the meantime, especially the BMW four cylinder diesels did well in tests, concerning their boost as well as their fuel consumption.
