Bridgestone Motorsport’s Bahrain Grand Prix Report


Brawn GP driver Jenson Button used a super soft – super soft – medium tyre strategy to win a thrilling Bahrain Grand Prix in searing hot conditions at the Bahrain International Circuit.
Button finished 7.1 seconds ahead of Sebastian Vettel, who used the same strategy in his Red Bull. Pole-sitter Jarno Trulli used a super soft – medium – super soft strategy in his Panasonic Toyota Racing car to finish second. Bridgestone’s super soft tyre worked particularly well here, even with a track temperature of over 50 degrees Celsius, delivering good grip and consistency.
Q&A with Hirohide Hamashima – Bridgestone Director of Motorsport Tyre Development
How was the race from Bridgestone’s perspective?
“Today was a very exciting race, particularly from a tyre perspective. We saw a good range of strategies, and when to use the medium compound was a difficult decision for teams, as it delivered a consistently slower lap time than the super soft. The super soft performed well and heat degradation was not a big problem even in the extreme heat of Bahrain. There was some very good tyre management from drivers and also some strong running from competitors on the medium tyre too. I think today has shown just how exciting racing can be with two Bridgestone tyres with different characteristics with our 2009 allocations.”

As the second dry race of 2009, does this help with the understanding of the 2009 tyres?
“We have accumulated a lot of good data from the first four race weekends and this has been very useful. The other fully dry race in Australia was unusual as the track surface did not evolve in the same way as we had seen in previous seasons, so the tyre performance did not improve as we predicted there. Here in Bahrain was interesting because of the extreme heat, but our tyres performed well, and continued to give competitors a challenge for how best to use them during the course of the race.”

distinguishable from each other. At the Bahrain Grand Prix, the super soft compound
Bridgestone Potenza tyres were marked with green bands on the sidewalls. The wet weather tyre was also marked with a green line in a groove.
