Formula One's governing body has offered Renault's second-in-command immunity from punishment in exchange for full disclosure about "crashgate," a report said Tuesday. Pat Symonds, director of engineering at Renault, has been told that if he comes clean over how and why Nelson Piquet junior drove his car into the barriers in Singapore in 2008, he will escape sanctions. The sanctions could include a life ban from the sport, according to the report in London-based The Times newspaper, which cites unnamed sources. Former driver Piquet and his father, three-time world champion Nelson Piquet senior, have claimed that the Renault team conspired to fix the outcome of the Singapore Grand Prix, in a blow to the sport's reputation. The offer of immunity from the International Motorsport Federation (FIA) comes after its stewards investigating the claims interviewed Symonds at the Belgian Grand Prix late last month.
