In 1992, after further development work was done to the gearbox, traction control and active suspension system, the FW14B was the dominant car and Mansell wrapped up the 1992 Drivers' Championship with a then record 9 wins in a season, whilst Patrese scored a further win at the Japanese Grand Prix. Patrese did not warm to the car as much as the FW14, as he preferred the passive suspension in that chassis, whereas the increased level of downforce generated by the FW14B suited Mansell's aggressive driving style much better. The main visible difference between the FW14 and FW14B were a pair of bulbous protusions above the latter's front pushrods, which contained the active suspension technology. The FW14B also featured a longer nose section. The result was that there were many races in the 1992 season where Mansell and Patrese would gain 2 seconds on the rest of the field, especially in the early laps, which made the FW14B far superior to even the next best car, the McLaren MP4/7A. Another example of Williams's dominance that year was at qualifying at the British Grand Prix at Silverstone, where Mansell's pole position-winning lap was a whole 2 seconds faster than Patrese, who in turn was a second faster than 3rd placed Ayrton Senna. Williams were clear winners of the 1992 Constructors' Championship, but the season ended in acrimony as Mansell left the team after Alain Prost was signed, while Patrese moved to Benetton for his swansong season in 1993. Both versions of the FW14 won a combined 17 grands prix, 21 pole positions and 289 points before being replaced with the FW15C for 1993. Given that current F1 regulations ban many of the technologies used by the FW14B and FW15C, these are considered among the most technologically advanced racing cars to have ever raced in Formula One. On 2 June 2017, the Williams F1 team celebrated 40 years in Formula One with a media day at Silverstone race circuit. The FW14B was driven for the first time since 1992.
