 It was only in Intercontinental Formula racing, with the addition of the version of the "FPF" straight-four, that the car showed some promise.Two such-equipped Mk4 cars were shipped to New Zealand and Australia for their respective Grands Prix in early 1963, where regular driver Surtees was partnered by up-and-coming South African Tony Maggs.In his last two races for the Bowmaker team, before signing with Ferrari, Surtees won the New Zealand Grand Prix and finished second in the Australian Grand Prix, a month later.
