The 24th and final round of the season got underway on Friday in Abu Dhabi.
The team ran all three tyre compounds across the two hours of practice, gathering data on both single lap work and the long run.
Both George and Kimi started FP1 on the Hard compound tyre in the warmer and slightly less representative conditions of that first hour.
They ended the session with Kimi in P4 and George P6 before returning to the track for FP2 later in the day.
In that more representative session, which sees the sun set halfway through, the team ran the Medium and Soft compounds.
Georged ended the hour P3 on the timing screens with Kimi, in a tight session, P10.
The team will now work through the data overnight, along with the usual overnight simulator programme at Brackley, before returning for FP3 on Saturday.
