The race follows a two-day test in Bahrain, so it will be interesting to see how the lessons learned there translate into on-track performance and tyre management in Russia. On the face of it, with Sochi being a low-severity circuit and more durable tyres this year, it should be a relatively straightforward one-stop race. However, this is the first time we are going there with the ultrasoft tyre, so the effect that it has together with the new generation of cars remains to be seen. The performance gap between the softest compounds is relatively small, so all three choices are potential race tyres in Sochi.
