Sebastian Vettel set the pace once again for Ferrari in the second Formula 1 practice running for the Bahrain Grand Prix, but lost track time after a complete shutdown on his SF70H car midway through the session on Friday evening.
Vettel topped the timesheets for Ferrari in FP1 ahead of Red Bull’s Daniel Ricciardo, and continued to set a rapid pace in FP2, turning in a best lap of 1:31.310 during the 90-minute session.
Vettel headed up a close-knit group at the top of the timesheets, with less than three-tenths of a second covering the Ferrari driver, Valtteri Bottas, Daniel Ricciardo, Kimi Raikkonen and Lewis Hamilton in fifth place.
Hamilton was left frustrated by traffic on his super-soft qualifying simulations, with the stewards set to investigate an incident involving Nico Hulkenberg that sent the Briton off-track.
Just as Vettel began to prepare for his long runs in the second half of the session, the German suffered a loss of power coming out of Turn 13, causing him to slow. Despite his best efforts to reset the car, Vettel required a push from the marshals to get back to the pits, costing him track time.
Ferrari was able to resolve the issue with relative ease, with Vettel staying in his car the entire time as it was fixed, losing around 10 minutes of running in total.
Behind the top five, Nico Hulkenberg put in an impressive display for Renault to finish sixth, with Williams’ Felipe Massa following in P7 ahead of Max Verstappen, who suffered damage after hitting debris that limited his FP2 running.
Haas driver Romain Grosjean wound up ninth ahead of Daniil Kvyat, who rounded out the top 10 for Toro Rosso.
Vettel was not the only driver to hit trouble, with Carlos Sainz Jr. also suffering a stoppage on-track that brought his session to an end with just five laps on the board.
Following his engine problem in FP1, Stoffel Vandoorne was forced to miss the first half of the session, but eventually emerged to complete some much-needed running for the ailing McLaren team.
