The Renault Formula One crash controversy, dubbed Crashgate by some in the media, is a sporting scandal perpetrated by the Renault F1 team who ordered Nelson Piquet, Jr. to crash deliberately during the 2008 Singapore Grand Prix, to gain a sporting advantage for his Renault team-mate Fernando Alonso.
On 28 September 2008, on the 14th lap of the Singapore race, the Renault R28 driven by Piquet crashed into the circuit wall at turn 17, necessitating a safety car deployment. The other Renault driver, Fernando Alonso, had previously made an early pitstop, and was promoted to the race lead as other cars pitted under safety car conditions. Alonso subsequently won the race after starting 15th on the grid. Piquet described his crash at the time as a simple mistake.
After being dropped by the Renault team following the 2009 Hungarian Grand Prix, Piquet alleged that he had been asked by the team to deliberately crash to improve the race situation for Alonso, sparking an investigation of Renault F1 for race fixing by Fédération Internationale de l'Automobile (FIA), the Formula One governing body. After an investigation, Renault F1 were charged with conspiracy on 4 September, and were to answer the charge on 21 September 2009.
On 16 September Renault stated that they would not contest the charges, and announced that the team's managing director, Flavio Briatore, and its executive director of engineering, Pat Symonds, had left the team.
On 21 September it was announced that the Renault F1 team had been handed a disqualification from Formula One, which was suspended for two years pending any further comparable rule infringements. Briatore was suspended from all Formula One events and FIA-sanctioned events indefinitely, whilst Symonds received a five-year ban. Their bans were subsequently overturned by a French court, although they both agreed not to work in Formula One or FIA-sanctioned events for a specified time as part of a later settlement reached with the governing body.
