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 GP 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 6 chassis were built and the serial numbers follow on from the FW14, so starting at 6 through to 11.
