MONTMELO, Spain -- Charles Leclerc kept Ferrari at the top of the timesheets in pre-season testing after a solid start to his first day with the team.
His fastest time was a 1:18.247, roughly a tenth of a second slower than Sebastian Vettel's best effort on the opening day. Both drivers were using the same compound tyre -- the C3 -- but Leclerc's lap was set on a slightly longer run, suggesting it could have been on heavier fuel.
Once again, Mercedes was off the pace of Ferrari but believed to be running heavier fuel loads. Five kilograms of fuel costs 0.
