A fortnight later, for the second time in three years, Britain staged two Grands Prix in one season; in July, the British Grand Prix was held at Silverstone, but the loss of a race in New York City made a date available in Europe towards the end of the season. The management team led by John Webb made a bid for it and won the right to host the Grand Prix d’Europe on 6 October. It was fitting that Nigel Mansell should score his first Grand Prix on this occasion, at the wheel of a Williams-Honda FW10B, completing the 75 laps of the Grand Prix Circuit, at a speed of 125.795 mph from Ayrton Senna's Lotus-Renault 97T and teammate Keke Rosberg in the other Williams. Alain Prost brought his &lt;a href="McLaren%20MP4/2"&gt;McLaren-TAG MP4/2B&lt;/a&gt; home in fourth, to win become the 1985 World Drivers' Championship.
