The BMW M1 supercar didn't get a real successor despite getting the ax in 1981. The BMW Nazca C2 from the early '90s, which was also designed by Giorgetto Giugiaro of Italdesign, would have been a likely candidate but the German marque decided to go against making it a production vehicle. One would argue that the i8 mid-engine hybrid was a spiritual successor but as we've mentioned, it's arguable.
