Porsche debuted the 962 at the 1984 24 Hours of Daytona with Mario and Michael Andretti driving the factory car which led the race until it retired during lap 127 with engine and gearbox problems. The first 962 to appear at Le Mans and indeed in Europe was also in 1984 when American Preston Henn entered one in the IMSA GTP class. The car, driven by Henn, Michel Ferté and Edgar Dören, was classified in 26th position despite their race ending after 247 laps with ignition failure.
