Greatest car was the 1992 FW14B Williams-Renault driven by Nigel Mansell to 14 poles positions (All races except Canada and Hungary), 9 victories (South Africa, Mexico, Brazil, Spain, San Marino, France, Britain, Germany, Portugal plus second places in Monaco, Hungary and Belgium.) and the World Drivers Championship with 108 points.
Riccardo Patrese took second overall with one pole (Hungray), one victory (Japan plus second places in South Africa, Mexico, Brazil, San Marino, France, Britain, thirds in Monaco and Belgium) and scored 56 points.
Williams dominated the constructors championship with 164 points, wrapping it up in Belgium with four races to go.
AND because the car was just a derivative of the 1991 car, could one also include the 1991 results?
