Paul Hembery: “The fact that there was no dry running prior to the start of the grand prix meant that formulating the right tyre strategy was a matter of educated guesswork for all the teams. And with no rubber having been laid down on the track previously, it was extremely hard to calculate the wear and degradation levels.
“The weather forecast remained uncertain throughout the race to complicate matters even further, with different teams interpreting the information in various ways. However, they had to bear in mind their obligation to run both compounds if conditions stayed dry – which turned out to be the case.
“This race has marked the end of an era and now the cars, along with the tyres, change completely for next year. Congratulations to Sebastian Vettel and Red Bull for a record-breaking season, and best of luck for the future to Mark Webber, who ends his distinguished Formula One career here in Brazil.”
