Drivers will be back on the track on Thursday afternoon, and also on Friday to close out the first week of testing. Teams will have another three days to test next week.

Preseason testing has been reduced from eight to six days to help compensate for the record 22 races on the calendar, including a new Vietnam Grand Prix and the return of the Dutch GP. Midseason testing also has been eliminated.
