Cheating allegations were made at the first round of the 1994 season, the Brazilian Grand Prix. On lap 21 of the race, Senna in the Williams who was leading the race, made a pit stop, with Michael Schumacher in the Benetton close behind. The Benetton pitcrew made a very quick stop for Schumacher, getting him out in front of Senna to lead the race. Schumacher went on to win the Grand Prix after Senna spun out of the race. This sparked speculation that Benetton was using a system to make quicker pit stops than their rivals.
