United States GP: Pirelli Friday quotes
Paul Hembery: "Today was all about familiarisation for the teams on what is the only brand new track of the year. With weather conditions being cooler than expected, the initial data suggests that both wear and degradation is very low on both compounds, which leads us to think that we will see just one stop on Sunday, but we will have to look at all the numbers in more detail tonight to have a clearer picture. Our data simulation work has proved to be extremely accurate, with both the compounds performing exactly as we expected, although we also have to take into account the high degree of track evolution that could certainly affect the strategy on Sunday

"We're seeing a performance gap of around half a second per lap between the two compounds, which gives the teams plenty of scope to try to gain an advantage through the timing of their pit stops. Nonetheless, as this is a completely new circuit with a number of potentially unknown factors, we deliberately opted for a conservative tyre choice here."
