Team Summary:
With the start of the opening practice for the 2018 season the Williams drivers were amongst the last to come out for their installation laps. There was a mixture of tyres been used with the drivers having the soft, supersoft and ultrasoft tyres to choose from. The first drivers to return would be the Williams pair with both on the ultrasoft tyre. After the first runs the quickest time was a 1m:25.694 set on the ultrasoft tyre. This would improve with a 1m:24.959 while for Williams their drivers were currently seventh and tenth. Both Williams drivers were on longer runs having completed ten laps with just under an hour remaining. The quickest time would drop to a 1m:24.914

After their first runs the Williams drivers were in tenth and eleventh. Lance was 0.6 ahead of his team-mate. After a short stop both Williams drivers would return for their second runs. The new quickest time was a 1m:24.531. Thirty minutes remaining and the quickest time would come down again with a 1m:24.147. In 2017 the quickest time in this session was a 1m:24.2. A 1m:24.026 would again see the quickest time come down. With their second runs complete the Williams drivers were tenth and thirteenth. Back out again both Williams drivers would continue their runs on used ultrasoft tyres having dropped to twelfth and fifteenth. This is where they would end the session. A positive start to the season for both Williams drivers. Sergey would finish ahead of team-mate Lance but it did appear that Lance had some issues with his car that may have hampered his session.
