Valtteri Bottas consolidated his position as the fastest man in Sochi after sweeping Friday practice at the Russian Grand Prix. The Finn again had the measure of teammate Lewis Hamilton in a comfortable Mercedes one-two result, although the pair was more closely matched than in FP1, with Bottas leading the way by just 0.044s.

Hamilton was fastest in the first sector, but he slipped more than 0.3s to Bottas at the middle split, which he couldn’t recover in the final part of the lap. The Briton then had a strange collision with his front jackman, arriving too hot in his pit box and knocking him over. He later explained that he’d accidentally left on the “brake magic” brake bias setting.

In the unlikely but nonetheless contemplated event FP3 and qualifying cannot be run this weekend, with heavy rain forecast for Saturday, the results of second practice will set the grid for Sunday’s race, earning Bottas pole position.

Valtteri Bottas led the way in first practice for Mercedes at the Russian Grand Prix ahead of title rivals Lewis Hamilton and Max Verstappen. The Finn, fresh from his strong performance at the Italian Grand Prix two weeks ago, went fastest with a time of 1m34.427s, beating teammate Hamilton by 0.211s.

Verstappen was third, just 0.016s further adrift, albeit with the championship leader using a second set of new soft tires late in the hour to set his best time, benefiting from rapidly improving conditions on the dusty street circuit. This flattered the Dutchman’s morning, and he ended the session with only 13 laps to his name and with his car on jacks in the garage.

It was an unusual example of a first practice session for the appearance of the red-walled rubber, which is usually held in its blankets for the more representative afternoon conditions. However, the high chance of rain on Saturday, including for qualifying, freed teams to use the fastest tire in what is ordinarily a session reserved for setup exploration, with every driver using at least one set each.
