Ahead of the auction house’s’The Grand Marques of the planet’ sale Thursday, the car was first introduced in Paris.
Motorsport.com understands that this particular FW14B took Mansell out to five of their nine victories he scored that season.
Due to its complex period electronic equipment which contained active suspension and traction control, the FW14B remained dormant until Williams’ 40th anniversary bash at Silverstone.
Ex-F1 driver Karun Chandhok, who is the driver of the Williams Heritage division subsequently drove it.
This is not the first time Bonhams has sold that a grandprix with provenance.
Bonhams motor sport manager Mark Osborne told Motorsport.com:”that is actually as good as it’s. This car contributed more on any other vehicle towards the championship in 1992.
“the very simple fact that it turned out to be a great Adrian Newey design, also he continues to be so totally applicable today as he was then, means I’d say it’s one of the main grand prix [cars] to come onto the marketplace today”
At its own Monaco sale last year, chassis six of those 1993 McLaren MP4/8s — the car that Ayrton Senna drove to his sixth largest and finale victory in the principality — and the Toleman-Hart TG184-2 that Senna drove in the renowned rain-soaked 1984 race to finish next to Alain Prost were also sold.
Reportedly, former F1 boss Bernie Ecclestone won the bidding on the MP4/8 in €4.1million, comparable to £3.6m at the time.
