1985 Belgian Grand Prix

The 1985 Belgian Grand Prix was a Formula One motor race held at Spa-Francorchamps on September 15, 1985. It was the thirteenth round of the 1985 Formula One season.

The top 5 finishers all were or went on to be World Drivers' Champion.

This race was originally to be run on 2 June but was re-scheduled to 15 September after the then newly laid surface had badly broken up. Because this was a re-scheduled race Formula One's newest team Haas Lola and their driver, ex-World Champion Alan Jones, who had debuted at the previous race in Italy were not permitted to enter as they were not on the original entry list.

Missing from the grid was an injured Niki Lauda. At the end of Friday's practice session before qualifying proper, his McLaren-TAG's throttle struck open while he was only touring back to the pits. The car slid off the track on the newer section of track and the three time (and defending) World Champion hit a guardrail and on impact the steering wheel whipped around wrenching his wrist as it did so. X-rays revealed no break but Lauda was not fit to race so he returned home to Austria for further inspection and treatment. McLaren initially hoped to put John Watson in Lauda's car but this would have required the approval of all other teams. Mindful of the Constructors' Championship, Ferrari refused to agree, leaving Alain Prost as McLaren's only driver in Belgium.
