BMW-Testgelände, Automotive test track in Aschheim, Germany

The BMW test facility is an automotive testing ground in Aschheim near Munich with multiple specialized tracks and measurement areas. The installation allows engineers to assess vehicle performance and safety comprehensively under controlled conditions.

The facility began operations in 1971 and became the center of BMW's vehicle development programs. Since then, it has served as a place where new technologies and vehicle concepts are tested.

The site is often called Testgelände Ismaning after the nearest larger town, although most of it lies in Aschheim, with the eastern part in Finsing and a small segment in Pliening. The straight four-kilometre track is built like a motorway, with two lanes in each direction. The site is fenced and closed to tourists; it is a working BMW test facility, not a visitor attraction.

The site is fenced and closed to the public; it is a BMW test facility, not a tourist attraction, so there are no tours or rental cars. It lies on the northern shore of the Ismaninger Speichersee, mostly in Aschheim, with the eastern part in Finsing and a small segment in Pliening. The four-kilometre straight track can be seen from outside the fence.

The ground features specialized measurement equipment and various road surfaces to test vehicle dynamics under different weather conditions. This variety of testing options allows engineers to validate vehicles realistically before they reach the market.
