Formula One Grand Prix
As the number of cars entered fell below 26, a new problem started. All cars entered would automatically qualify for the race. Some cars were much slower than most of the other cars. The 107% rule was introduced in . If the qualifying time of a car was not within 107% of the pole time, the car would not qualify for the race. For example, if the pole time was 1m 30s, the slowest a car could go to qualify would be 1m 36s. The race stewards could allow a slow car to race if they thought there was a good reason for it being slow. For example, rain may have slowed down the qualifying session.
