Major Anthony Peter Roylance Rolt, MC & Bar, was a British racing driver, soldier and engineer. A war hero, Rolt maintained a long connection with the sport, albeit behind the scenes. The Ferguson 4WD project he was involved in paid off with spectacular results, and he was involved in other engineering projects.

Four-wheel drive (4WD) has only been tried a handful of times in Formula One. In the World Championship era since 1950, only eight such cars are known to have been built.
