The E32 introduced numerous features including adaptive suspension (EDC), traction control, two available wheelbases (i and iL), and dual-zone climate control. The E32 750i was the first car adhering to "gentlemen's agreement" amongst the German manufacturers limiting maximum speed to 250 km/h (155 mph).

In 1994, the E32 was replaced by the E38, a clear evolution of the E32.
