Ferrari and Sebastian Vettel led the way Wednesday morning in Abu Dhabi for the second day of Pirelli's tyre test at Yas Marina.
Vettel clocked in before lunch with a 1:37.551lap which was slightly faster than team mate Kimi Raikkonen's fastest Tuesday time.
Once again the Scuderia was clear of its rivals, with Force India's Esteban Ocon ending the morning second, over 1.5s behind Vettel.
Before Robert Kubica's resumes his test with Williams later this afternoon, Sergey Sirotkin put the FW40 through its paces, the Russian setting the seventh fastest lap for his first run with the British team.
Junior drivers Lando Norris and Charles Leclerc both took to the track, for McLaren and Sauber respectively while Stoffel Vandoorne took over from Fernando Alonso as the team's main runner.
