About the Williams FW14B
The FW14B was the 1992 development of Adrian Newey's FW14, adding active suspension and traction control to further work on the semi-automatic gearbox and aerodynamics, with a 3.5-litre Renault V10. Nigel Mansell won a then-record nine races and the Drivers' Championship, Riccardo Patrese won in Japan, and Williams took the Constructors' title. The car was often two seconds a lap quicker than the rest, and at Silverstone Mansell's pole time was two seconds faster than Patrese, who was another second clear of Ayrton Senna. Patrese preferred the passive FW14, but the extra downforce of the active car suited Mansell's aggressive style.
