Jean-Denis Delétraz

The slow qualifying speeds of drivers like Delétraz resulted in the introduction of the 107% rule for the 1996 season - with some F1 fans nicknaming the new regulation the "Delétraz rule" as a result.

After his tenure in Formula One, Delétraz focused on endurance racing, running in the 24 Hours of LeMans and the BPR Global GT Series in 1995. 1996 saw Delétraz move to the FIRST Racing operation he now co-owned with fellow driver Fabien Giroix. Two years in the BPR Global GT Series in a McLaren F1 GTR was followed by a move to the FIA GT Championship in 1997, with FIRST running the works Lotus Elise GT1s. After a couple of years away, FIRST and Delétraz returned to the FIA Championship in 2000 with a Ferrari 550 Maranello. In 2002, he took four wins in the series with team-mate Andrea Piccini in a BMS Scuderia Italia-run 550, and the pair finished fifth in the championship. They then drove a works Lister Storm in 2003. He has also scored two class wins at the 24 Hours of Le Mans, in 2001 and 2002 in the LMP675 class. He was also one of the drivers of the Chevrolet Corvette C6.R that won the 2007 Spa 24 Hours.

Towards the end of 1994, Larrousse was, like a number of other teams at the time, running short of money and needed pay drivers to keep the team afloat. Larrousse's number 19 car, which had started the year being driven by Olivier Beretta, was now being driven by drivers who could bring sponsorship money to the team. For the final race of the year in Australia, Larrousse let the aero-car inexperienced, physically unfit Delétraz replace Érik Comas in the team's second car for more sponsorship money in order to aid their financial situation.

In 1992 and 1993, Deletraz competed in the French Touring Car Championship and the Porsche Supercup with little success. In 1994, Delétraz was signed as a driver for the SEAT works team in the French Touring Car Championship. His best result was fifth place in the race at Nogaro and he finished thirteenth overall in the standings.

Delétraz had some success in his early career, including two wins in Formula Ford cars. He went on to compete in Formula Three between 1985 and 1987 in the French championship, finishing 14th in the final standings in 1987. Between 1988 and 1991, he competed in Formula 3000 and during 1990 he bought the FIRST racing team, but was never able to match the success of 1988 and scored no points. During 1991 the team was impounded by an Italian court for a time after legal action from the team's other driver, Giovanni Bonanno.

Jean-Denis Delétraz (born 1 October 1963) is a Swiss racing driver. He participated in three Formula One Grands Prix, debuting in the 1994 Australian Grand Prix. Before reaching Formula One, he scored two third places in the 1988 Formula 3000 season, but principally earned his three Formula One drives as a pay driver. After Formula One, he competed in sports car racing, with two class wins at the 24 Hours of Le Mans.

During qualifying, Delétraz qualified in 25th position, ahead of Simtek's Domenico Schiattarella. However, Schiattarella overtook him during the first lap of the Grand Prix, and Delétraz gradually dropped back from the rest of the field. He retired on lap 57 with gearbox failure, after he had already been lapped ten times. He was lapping the circuit six seconds slower than the leaders, two seconds slower than his teammate Hideki Noda and 1–2 seconds slower than the next slowest driver Schiattarella. He was described by BBC commentator Jonathan Palmer as "having no business in Formula One."
