Like in preseason testing, Mercedes AMG Petronas topped the timesheets in first practice for the Russian Grand Prix but the story of the session was elsewhere as one of the new cockpit enhanced devices made its debut at the start of practice.
Nico Rosberg was fastest in the W07 at 1:38.127 on Pirelli’s supersoft compound, while Daniel Ricciardo introduced Red Bull Racing’s new Aeroscreen to the world for an installation lap.
The device was installed on Thursday and Ricciardo rolled out with it to start practice. Following an installation lap it was back to removing the device and running in standard configuration. The Aeroscreen is one of two cockpit enhancement devices to have made its debut this year, Kimi Raikkonen having rolled out the “Halo” concept at Barcelona for preseason testing.
Alas in practice, several drivers spun on the low-grip Sochi Autodrom circuit – Lewis Hamilton at Turn 2, Jenson Button at Turn 15 and Sebastian Vettel at the same corner shortly thereafter, and local hero Danill Kvyat later in the session at Turn 17. Jolyon Palmer also had a spin at Turn 17 just after the checkered flag.
Further down the grid Manor Racing had a difficult start to the session with a floor change on Pascal Wehrlein’s chassis and an unspecified technical issue for teammate Rio Haryanto. Both made it out for some laps later in the session.
Rosberg topped Hamilton by 0.722 of a second with Vettel third, Raikkonen fourth and Felipe Massa fifth. Ricciardo was sixth in his usual car configuration.
Two drivers stepped in for race drivers this session, with Russian Sergey Sirotkin ending a respectable 13th in his debut with the team in FP1.
That being said, his number choice of 46 inspired Kevin Magnussen, who was sidelined for the session, to throw a bit of shade on Sirotkin after getting the Romain Grosjean treatment in sitting out.
Alfonso Celis Jr. also ran for Sahara Force India in place of Nico Hulkenberg and propped up the timesheets, 5.305 seconds off Rosberg and a full 3.1 seconds and change behind teammate Sergio Perez in ninth.
