Tactics and tyre management played an important role during this evening’s race. Conditions were as tough as ever in Singapore, with the heat, humidity and sheer length of the race, but Ferrari and Sebastian Vettel were able to get the very best out of the tyres and the strategy, knowing when to push and when to keep something in reserve. It was a perfect race from him. The strategy for every team was obviously affected by the two safety car periods, which had the effect of stretching out the stints. As a result, we saw more drivers moving towards a two-stop strategy rather than a three-stopper. All the way down the field though, there was some different thinking about which order would be the best one to use the tyres in. With such a long race distance, looking after the tyres most effectively was crucial to success, especially in the closing stages.
