Hirohide Hamashima - Bridgestone Director of Motorsport Tyre Development
What was significant about today's running?
"Today was a challenge for all the drivers as the grip level in Monaco is very difficult to learn, and any mistakes are punished by the barriers. There are significant sections of resurfacing, however the new surface is very smooth, just as the older sections of track are, so there is not a significant difference between the two from a tyre performance perspective.
"As a first day at Monaco, we saw the lap times fall dramatically over the course of the day as the track cleared and the rubber was put down. It was a good day in terms of gaining data as the weather was fine and the running was not interrupted. However, we will not see any F1 running here tomorrow, so it will be interesting to see how the track surface changes for Saturday."
How do you expect this allocation to work over the weekend?
"Even though these are our softest tyres, drivers will struggle for grip here due to the unique slippery nature of this track. Despite this, we saw very good displays from the drivers today with some exceptional car control, as we would expect of the best drivers in the world.
"The super soft tyre was faster than the soft tyre, as we expected. The difference between the two tyres today was around 0.4 seconds over the fastest lap. Both tyres delivered their fastest lap on the first or second flying lap, and neither tyre suffers greatly in terms of wear or degradation because of the low grip here."
