Vettel seals title at Brazilian Grand Prix

Red Bull driver Sebastian Vettel has claimed his third consecutive world title – making him the youngest-ever triple world champion – after a dramatic Brazilian Grand Prix, while McLaren’s Jenson Button took his third win of the season. Vettel stopped four times en route to a sixth place finish, having lost time with a spin and sustained damage following contact with another competitor on the opening lap. The P Zero Silver hard tyres and P Zero White medium were nominated for the race, while the Cinturato Green intermediates and Cinturato Blue full wets were also used.

All the drivers started on the medium tyre apart from Michael Schumacher (Mercedes), Kamui Kobayashi (Sauber) and Romain Grosjean (Lotus), who began on the hard tyre. The race started in ambient temperatures of 19 degrees with light drizzle, but the rain intensified during the first 10 laps. Lotus driver Kimi Raikkonen was the first to pit for Cinturato Green intermediates, on lap five, followed progressively by many other drivers all the way down the field.

Button, who claimed an early lead from second on the grid, stayed out on the medium tyres while the rain fell. The different strategies shook up the established order: the Caterham of Heikki Kovalainen running as high as sixth overall, ahead of the Marussia of Timo Glock in seventh – who also both remained on the slicks until laps 15 and 14 respectively.

When the safety car came out for 10 laps, Button pitted on lap 23 for hard tyres while the track still remained damp as the rain eased off. In the closing stages of the race, the rain returned with a vengeance, meaning that it was no longer possible to stay out on the slicks.

On lap 50 Mercedes driver Nico Rosberg went onto the intermediates, while Vettel stopped for medium tyres on lap 52 and then two laps later for intermediates as the rain fell harder. On lap 57 Button made his second and final stop onto intermediate tyres without losing the lead. Toro Rosso’s Daniel Ricciardo and Kovalainen ended the race on the Cinturato Blue full wet tyre.

Vettel’s tyre strategy consisted of starting on the medium tyre, switching to the intermediate, then to the hard, then to the medium, and finally to the intermediate again. His title rival Fernando Alonso, who needed to finish at least third with Vettel 10th or lower to claim the championship, made one less stop: starting on the medium, then to the intermediate, then to the medium, then to the intermediate again.

The regulations state that drivers have to use both slick compounds during the race unless they have used either the intermediate or wet tyre. Button was the only finisher to stop just twice: all the others made at least one more stop.
