With Russia now re-established in its autumn date, having moved back to this slot last year, it's going to be interesting to see what has changed compared to 2018. We're bringing tyres from the middle of the range this year – a step harder than last year – which should be well-adapted to a wide variety of conditions. Longitudinal rather than lateral forces are the main influence on the tyres here, with a high degree of track evolution throughout the weekend. Anticipating the set-up and tyre strategy with regard to the changing requirements of the track will be one of the keys to success in Sochi. A new absolute lap record was set last year by Valtteri Bottas in qualifying last year – let's see if that is lowered further this year.
