From the archive: 1986 Spa 24 Hours

The BMW 635 CSI shared by Roberto Ravaglia, Gerhard Berger and Emanuele Pirro rounds La Source on its way to third place in the 1986 Spa 24 Hours. Although Berger was unable to repeat his victory from the previous year, it was an event dominated by the 635, which took the top four positions, and the winning crew were Berger’s BMW Belgium team-mates Dieter Quester, Altfrid Heger and Thierry Tassin.
