It had been one of the most frantic close seasons ever with only Ronnie Peterson, Denny Hulme, Carlos Reutemann and James Hunt remaining with their teams. Emerson Fittipaldi moved from Lotus to McLaren to be replaced by Jacky Ickx. McLaren now had sponsorship from Marlboro and Texaco. The team also entered a third car in their old colours of Yardley for Mike Hailwood. Hailwood's place at Surtees was taken by Jochen Mass where he partnered Carlos Pace, whilst Peter Revson had moved from McLaren to Shadow, where he was joined by Jean-Pierre Jarier.
