The 1970 South African Grand Prix, officially known as the XV South African Grand Prix, was the opening race of the 1970 FIA Formula One World Championship, staged on the 7th of March 1970. Held at the Kyalami Circuit near Johannesburg, the opening round of 1970 saw a relatively large entry list, despite a rather turbulent winter for the top teams. As Brabham attacked Denny Hulme was charging, climbing up to third as the Australian snatched the lead. The New Zealander's charge carried him onto the back of Stewart, and a lap long scrap saw the orange McLaren put the blue March down to third.
