Vettel seals strategic two-stop victory in Japan
Bull driver Sebastian Vettel has taken his fourth win in Japan and his ninth of the year, but that hasn’t quite been enough for the German to claim his fourth consecutive drivers’ title as Ferrari driver Fernando Alonso finished fourth in Japan from eighth on the grid. Vettel used a two-stop strategy to defeat his team mate Mark Webber, who stopped three times, and the Lotus of Romain Grosjean, who also stopped twice.
All the drivers started on the P Zero White medium tyre, nominated with the P Zero Orange hard tyre for Suzuka, apart from Toro Rosso’s Daniel Ricciardo and Caterham’s Charles Pic. Grosjean took the lead from third on the grid when the lights went out: the start of an intense tactical battle between him and the two Red Bulls that would last throughout the race.
Webber was the first of the leading three to stop from second place on lap 11 for hard tyres, hoping to use strategy to get past Grosjean. The Lotus driver pitted on the following lap for hard tyres from the lead, leaving Vettel in front.
Vettel’s first stop was on lap 14 for hard tyres, rejoining in third with Grosjean and Webber in front. The final driver to make his first stop was Ricciardo, who pitted for another set of hard tyres from on lap 21, having climbed up to fourth in the early stages.
Webber’s second stop took place on lap 25 for hard tyres again, aiming to ‘undercut’ Grosjean for the lead once more with the timing of his pit stop. This time the strategy worked: Grosjean’s second stop was on lap 29 for more hards and he rejoined in third behind Vettel and Webber.
Vettel made his second and final stop for the hard compound on lap 37, with 16 laps to go. He slotted back into third, but with Webber pitting once more and Grosjean running a 24-lap final stint, the German’s strategy was the winning choice.
With 11 laps to go, Webber put on the faster medium tyres at his third stop and set off to chase Vettel and Grosjean, taking second place with just laps to go. The top three finished within 10 seconds, despite adopting very different tactics.
Pirelli’s motorsport director Paul Hembery said: “This was always going to be a very close race, with little difference in lap times between the two nominated compounds. As a result we saw varied approaches to strategy, with both the medium and the hard tyre being used at different points for the second and third stints. The majority of drivers stopped twice as we expected: wear is quite low at Suzuka due to the flowing nature of the circuit – which means that traction demands are low – but the high lateral energy loads mean that the limiting factor is degradation. This of course is exacerbated when you have a close race with the cars following behind each other, as aerodynamic efficiency is compromised and the cars slide more. Vettel was able to use a two-stop strategy to make the difference here, but it was extremely close with Webber and Grosjean. Once more we received a great welcome in Japan: one of the most difficult circuits in the world for drivers, cars and tyres, with an absolutely amazing atmosphere thanks to some fantastic fans.”
Fastest times of the day by compound:
|First||WEB – 1.34.587||ROS – 1.34.650||N/A||N/A|
|Second||RIC – 1.35.020||VET – 1.35.317||N/A||N/A|
|Third||BUT – 1.35.549||RAI – 1.35.516||N/A||N/A|
Longest stint of the race:
|Medium||18 laps||C. Pic|
|Hard||27 laps||P. Di Resta|
Our prediction for the 53-lap Japanese Grand Prix strategy was two stops. We suggested that the fastest strategy was to start on the medium, change to medium again on lap 20 and then change to the hard on lap 37. The alternative strategy was: start on the medium, switch to hard on lap 20, and hard tyre again on lap 37.
In the end, the teams mostly went for a variation on the second suggested strategy, but a bit earlier than we expected for the first stop – largely as a result of running in close formation. Vettel followed the medium-hard-hard strategy, stopping on laps 14 and 37.
