In 1992, after further development work was done to the gearbox and aerodynamics, and electronics technology such as a traction control and active suspension system were added, the B-spec. FW14, known as the FW14B was introduced for the 1992 season. The FW14B was the dominant car that year 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 protrusions above the latter's front pushrods, which contained the active suspension technology. The FW14B also featured a longer nose section. The car had been present at the Australian Grand Prix the previous year, but Mansell had elected to use the regular FW14 in that race. The result was that there were many races in the 1992 season where Mansell and Patrese would gain 2 seconds per lap 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 for a number of laps by
Karun Chandhok. The car did several laps on its own around the circuit; it then performed 3 laps accompanying the 2014
Williams FW36 driven by
Paul di Resta. A total of six chassis were built. The numbering continued from the FW14, so FW14B serial numbers 6 through 11 were built. In 2020, it was revealed that
Sebastian Vettel bought
Nigel Mansell's no. 5 FW14B, the same chassis that won the 1992 F1 world title. ==Cultural legacy==
