Drivers
An all new driver line-up was featured. Triple world champion Alain Prost had signed with Williams for the 1993 season, having spent the previous year out of motorsport competition on a sabbatical. Reigning Champion Nigel Mansell departed Formula One, over a dispute with Frank Williams with money and the signing of Prost, to race in the American CART series for 1993, while Riccardo Patrese moved to Benetton-Ford. Mika Häkkinen was considered for the vacancy left behind before the team decided to promote Damon Hill, the team's test driver for the past two years, who had made two starts for Brabham in 1992. Williams retained this driver pairing in all 16 races in 1993.
Triple World Champion Ayrton Senna, who had previously had a test with Williams in 1983, had repeatedly tried to get Frank Williams to sign him and even went so far as to offer his services for free, but a clause in Prost's contract specifically forbade Williams signing Senna as Prost's team-mate and the Brazilian instead opted to remain at McLaren on a race-by-race basis. However, Prost's clause only covered the 1993 season.
