Sebastian Vettel has topped the timesheets at the final pre-season test day, however his day was cut short by an electrical problem.
Vettel pulled to the side of the track with two and a half hours to go in the session, and Ferrari soon confirmed that the problem would not be fixed on time for him to be sent back out.
Despite the premature end, Vettel managed to rack up 100 laps, with his fastest time reading a 1:16.221. However, his lap was just 0.003s faster than Lewis Hamilton's who ended the session in second place.
Valtteri Bottas was third, as he handled driving duties for the Silver Arrows this morning. He headed Nico Hulkenberg, with Carlos Sainz and Daniil Kvyat the only other drivers who posted a sub 1:17 lap time.
Romain Grosjean, who drove the morning session, was seventh for Haas. The team's day ended poorly, as Kevin Magnussen stopped in the final minutes. Magnussen rounded out the top ten, behind Daniel Ricciardo and Kimi Raikkonen.
Red Bull's day was hampered by a gearbox problem, with Max Verstappen clocking just 29 laps for the energy drink squad. The Dutchman was eleventh, ahead of Sergio Perez and Robert Kubica who rounded out the timesheets.
