Despite the death of Ferguson in 1961, the Ferguson P99 was raced during the 1961 season in UK F1 races by Rob Walker's team. The car raced only once in the World Championship at the British Grand Prix. However the car won a non-championship race, the 1961 International Gold Cup at Oulton Park with Stirling Moss as the driver. As of today, this is the only victory of a four-wheel drive car in F1 (and incidentally the last race won by Moss in Europe), with the technology banned in 1983. Despite its promising beginnings this front-engined car was soon made obsolete by mid-engined cars.
