Hirohide Hamashima - Bridgestone Director of Motorsport Tyre Development
What are the challenges of Turkey?
"Istanbul has a wide range of different corner types and is a very difficult circuit to master in terms of car set-up and maximising tyre potential. It has high speed sections and also heavy braking. Both of these factors mean that a lot of energy is being put through the tyres, so watching wear and degradation will be a consideration. This circuit is not only a challenge for our tyres, drivers face a tough race too as the circuit is not clockwise like most of the tracks on the calendar."
How should the tyres cope with the tricky Turn Eight?
"Turn Eight is a difficult corner and we have learnt a lot about this corner from the problems we have seen here in the past. This season we are using slick tyres, and they are inherently stronger in the tread than a grooved tyre. In addition, we developed the tyres using the data gained here previously, so we are not predicting any issues, however we are always vigilant as this corner produces the highest G forces we see all season."
