Much has been written about the fact that Mercedes have never been beaten at the Russian Grand Prix, but after the first day of free practice at Sochi Autodrom it appears that Ferrari are intent on changing this statistic as Sebastian Vettel ended the day fastest of all with teammate Kimi Raikkonen second best on the day.
Vettel's best lap time of 1:34.120 was a quarter second faster than Raikkonen's best, which also happened to be 3.5 seconds faster than the time set in the same session last year.
Next up were the Mercedes duo with Valtteri Bottas fractionally faster than teammate Lewis Hamilton, but notably they were over half a second shy of Vettel's top time.
Fifth place in the session went to Max Verstappen whose qualifying run resulted in a three tenths of a second advantage over sixth-place team-mate Daniel Ricciardo. The session ended in disappointment for the Dutchman, though, as he was force to pull over at the side of the track 20 minutes before the end, reporting a power loss.
Behind the top three teams the midfield battle again looks tight, with just three tenths of a second separating seventh-placed Felipe Massa of Williams from tenth-place Sergio Perez of Force India.
Massa finished just six hundredth of a second clear of Renault’s Nico Hulkenberg, with Haas’ Kevin Magnussen just under two tenths further back in ninth place.
Elsewhere, Fernando Alonso was a decent 12th for McLaren, finishing behind the second Force India of Esetban Ocon, but there were more problems for the team as it was forced to change Stoffel Vandoorne’s power unit.
Lance Stroll was the only driver not to use ultrasoft tyres during the session, with the result that the second Williams driver finished in 19th place, 1.5 seconds slower than team-mate Massa.
