Forty years ago, driving Colin Chapman’s revolutionary Lotus 49 and the then still relatively new Ford Cosworth DFV engine, Jim Clark won the South African GP at Kayalami.  This would prove to be the last of his 25 Formula One victories — then the career record — and the beginning of a new era of advertiser-sponsored cars that Clark would sadly never see, killed just six months later in a meaningless F2 race in Germany.
