Kimi Raikkonen (Ferrari) was quickest on the first of the two-day Pirelli tyre test at the Yas Marina Circuit. Lewis Hamilton (Mercedes) and Romain Grosjean (Haas F1) were the most productive drivers with each completing 136 laps.
Although the main goal of the test is to try the 2018 Pirelli compounds, Williams took the opportunity to test Robert Kubica. The Polish driver is still a contender for the remaining seat next to Lance Stroll. Kubica managed 100 laps, without any physical issues.
Most teams used the test to try now parts for the 2018 season. Additionally, teams ran halos (mandatory for next year) as well as plenty of aero rakes and flow viz paint to gather as much data as possible going into the winter break.
