TOP SIX FINISHERS USE THREE-STOP STRATEGY IN BRAZIL: RAIKKONEN STOPS TWICE
HOTTEST TRACK TEMPERATURES IN RECENT HISTORY AT INTERLAGOS, COMBINED WITH NEW ASPHALT, PROVIDE A BIG CHALLENGE FOR TYRES IN FIRST STINT
CLOSE TACTICAL BATTLE BETWEEN MERCEDES DRIVERS FOR VICTORY
Sao Paulo, November 9, 2014 – Mercedes driver Nico Rosberg has closed the gap in the drivers’ championship to his team mate Lewis Hamilton after winning the Brazilian Grand Prix from pole, using a three-stop strategy. Rosberg did an opening stint on the soft tyre and then completed the race with the medium tyre, in high temperatures that were in contrast to the expected rain.
Hamilton adopted a similar strategy to finish runner-up, 1.5 seconds behind his team mate, after losing some time when he ran wide earlier in the race. After both made their final pit stops, Hamilton was able to use tyres that were one lap fresher to challenge Rosberg for the lead, setting up an exciting finale. In the end, Rosberg sealed his eighth career victory and his fifth win of 2014.
Most drivers started on the soft tyre, which was up to a second per lap faster around Interlagos than the medium compound. Force India’s Nico Hulkenberg adopted an alternative three-stop strategy, using the medium tyre from the start until his final stint on the soft. The extra speed at the end of the race helped him to finish eighth, making up four places from his grid position. Daniil Kvyat (Toro Rosso) used a similar strategy to finish just outside the points from the penultimate place on the grid.
As expected in the high track temperatures of more than 50 degrees – the highest seen at the Brazilian Grand Prix in recent years – the theoretically fastest three-stop strategy was used by nearly all the drivers. The highest-placed driver to stop only twice was Ferrari’s Kimi Raikkonen, who finished seventh after a thrilling battle that was just as intense as that which took place at the very front of the field. The drivers’ championship will now be decided at the final race of the season in Abu Dhabi, with double points on offer.
Pirelli’s motorsport director Paul Hembery said: “We saw a mesmerising battle between the two Mercedes drivers, during which they had to balance their desire to beat each other with the need to get the most out of the tyres in these very high temperatures. Ambient and track temperatures were certainly higher than everybody anticipated, which caused some degree of blistering and graining, particularly at the start of the race with heavy fuel, soft tyres and the hottest temperatures of the day. This did not however affect tyre performance. The new surface created a number of challenges for everyone all weekend, including the teams, the drivers and ourselves. Most drivers went for a three-stop strategy, which we predicted to be the fastest around Interlagos. However, Kimi Raikkonen made a two-stop strategy work as well, at one of the most demanding races of the year. ”
Fastest times of the day by compound:
Medium Soft Intermediate Wet
First Ham 1m13.555s Hul 1m13.728s
Second Ros 1m13.619s Gro 1m14.070s
Third But 1m13.999s Kvy 1m14.144s
Longest stint of the race:
Medium Raikkonen (36 laps)
Soft Hulkenberg and Kvyat (11 laps)
We predicted three stops as theoretically the fastest strategy for the 71-lap race, and because of the high degree of tyre wear as well, this was adopted by all but one of the competitors. Our prediction was a short stint on soft before changing to medium; medium again on lap 21 and a final stint on the medium from lap 46. Rosberg followed this pattern exactly, stopping on laps seven, 26 and 50.
