As expected on any temporary circuit, it was a particularly slippery start in Baku with a very green track and smooth surface. The layout of this track is a test of traction in particular, with the rear tyres doing all of the work. On top of that, there are only short corners in Baku, which means that the fronts are less stressed, and they also cool down a bit on the long straights between those corners. Consequently, finding the right set-up to ensure the correct balance between front and rear tyre temperature is essential to a strong performance here – as we saw in Russia, Monaco and Canada as well – and this is what a lot of the work concentrated on today. When analysing today’s data, we have to bear in mind as well that the track will evolve further as the weekend goes on.
