Mansell meets old foes in Grand Prix Masters
The Grand Prix Masters concept pitches ex-Formula One drivers aged 45 or over against each other in high-powered single-seater cars, with the first race at Kyalami in South Africa on November 13.
Mansell will be on the grid alongside former champions such as Emerson Fittipaldi, Alain Prost and Alan Jones, with Walker confirming he will come out of retirement to commentate.
