Mercedes driver Lewis Hamilton stormed to victory at the British Grand Prix for the second time in his career, using a two-stop tyre strategy.
It is Hamilton’s 27th career win and takes him to within just four points of the championship lead.
The race was red-flagged following an accident on the opening lap, with an hour’s delay for barrier repairs. As the re-start was a continuation of the race that had already started, drivers were allowed to change their tyres on the grid. Providing both compounds were at some point used, any driver switching compounds during that period would theoretically not be obliged to change tyres again during the race.
Ferrari’s Fernando Alonso switched from hard to medium, while the Red Bulls of Sebastian Vettel and Daniel Ricciardo, Jean-Eric Vergne (Toro Rosso), Romain Grosjean (Lotus) and Sergio Perez (Force India) made the opposite move from medium to hard.
Paul Hembery, motorsport director for Pirelli tyres, said: “The restart at the beginning of the race obviously had an effect on the tyre strategy, with a few drivers taking advantage of the situation to switch from their original strategy.
“We saw some quite opposite approaches being taken, with most drivers who changed moving to the harder tyre, while Alonso was able to exploit the extra speed of the medium tyre – worth about a second a lap – to gain track position after the re-start.
“The same story continued throughout the race with a number of different approaches to strategy. Even though Silverstone contains the highest lateral energy loadings of the year, seven drivers in the top 10 proved that it was possible to one-stop, which says a lot about the durability of these tyres.
“Even Lewis Hamilton, who took a brilliant home win, could probably have stopped just once.”
