most ever in a Formula One field, as well as Mexican Pedro Rodríguez, who was making his Formula One debut. Race day was bright and clear with a record crowd of nearly 60,000. A dummy grid was used for the first time in a Championship Grand Prix, and when the field moved forward to the starting grid, Clark's Lotus remained still. At the flag, Hill led Ginther, Surtees, Gurney, Tony Maggs, Gregory and Brabham up the hill and through the Esses. The Lotus crew discovered that Clark's battery was dead, and by the time they replaced it, Broeker's Stebro, trailing the field, was already into his second lap. Surtees made the first move, getting by Ginther to split the BRM's, and then, on lap seven, taking the lead from Hill. Gurney followed him and took second briefly, before surrendering the spot back to Hill. By lap 15, Clark was up into 14th place with his engine still not sounding entirely right. Hill began pushing Surtees on lap 30. He got by to take the lead after shadowing for two laps, gave it back, took it again two laps later, and finally surrendered it again, settling into the Ferrari's slipstream. On lap 43, Gurney suddenly slowed and then retired from third place with fuel starvation and a chassis failure, moving Clark up to seventh. After trailing Surtees closely for some time, Hill lost his tow when his anti-roll bar came loose and the BRM's handling changed abruptly. Fighting severe understeer, he began throwing the car into turns to slide the rear end around, flinging stones off the curbs and losing ground to the leading Ferrari. On lap 82, with no threat to his lead, Surtees's engine lost power, and he cruised into the pits to retire. "I was just hanging on to him," Hill said afterward. "He's a very tricky driver. He was gaining a half-second each lap on me until he went out. I think it was a good measure of the difference in our two cars." Suddenly in the lead again, with only Ginther on the same lap, Hill backed off and set his sights on bringing the car home. The Englishman drove under the flag 34 seconds ahead of teammate Ginther, repeating BRM's season-opening sweep at Monaco. New World Champion Clark took the final podium spot when he overtook Brabham, whose engine had been misfiring for much of
