ABU DHABI -- Kimi Raikkonen topped the first day of Pirelli's Abu Dhabi tyre test as Robert Kubica's crucial test with Williams saw him log a century of laps.
The Yas Marina test is primarily for teams to collect data on Pirelli's 2018 tyre range but Williams is using it to shape its decision on next year's driver line-up, with Kubica believed to be the frontrunner. The Pole, driving at the circuit where he contested his last F1 race in 2010 before suffering life-threatening injuries in a rallying crash the following October, completed 108 laps.
Though also helping the team collect valuable tyre information, the Pole logged several consistent 14-lap stints on a day he would later rate as "productive and intense" when speaking to the media after the session.
