The final day of the Williams martini teams per-season testing would get
underway with Sergey Sirotkin carrying out the driving duties in the morning
session. Sergey would complete the usual installation lap with his first run
seeing him on the ultrasofts. He would set a 1m:23.239 improving with a
1m:22.612 prior to pitting. His next run would see him back out on the
medium tyre but his red would be stopped due to a red flag. Sergey had
completed fourteen laps prior to pitting. With the restart Sergey would head
straight back out and would improve with a 1m:20.963 prior to pitting for
another red flag.
His next run would see him out on the soft tyre and it would also see a
further improvement with a 1m:20.750 prior to pitting again. He had
completed thirty two laps at this point. Sergey would continue his use of
the soft tyre and would set an improved 1m:20.377. Sergey was able to put in
a 1m:20.250 just prior to pitting. He had completed fifty nine laps at this
point. It was confirmed that Robert Kubica had given up his time in the FW41
preferring to see Stroll get more time in ths car.
Midday and Sergey would return for further laps on the soft tyre. His run
would come to an end having completed now seventy two laps. With there been
no lunch break Sergey would head back out for what would be his last run in
testing. He would again improve his time with a 1m:19.996 still on the soft
tyre. Sergey would pit but would return and would set a 1m:19.837 to lower
his quickest time still on the soft tyre. He would pit and would return this
time on the supersoft tyre. He would again improve with a 1m:19.189. After a
short run he would pit having now completed ninety three laps. Sergey's next
run was on the ultrasoft tyre as he continued to try various compounds. He
would complete his run pitting having completed one hundred and five laps.
After a break Lance Stroll would come out for his first run using the soft
tyres. He would set a slow 1m:29.852 on his first lap but would improve with
a 1m:21.318 and a 1m:20.938. This was a second slower than the best soft
tyre time set by Sergey. Another improvement of 1m:20.523. He would pit
after an eight lap run. After a short break Lance would return to the track
still on the soft tyre. A two lap run and he would pit again. Lance would
make one final improvement with a 1m:19.954 but remained at the bottom of
the times as the session came to an end.
Paddy Lowe, Chief Technical Officer: A far better day than yesterday with
Sergey running a long half-day across lunchtime up until 14:30, without any
issues, but not perfect as Lanceís final two hours in the car were
interrupted by a failure in the fuel system. Sergey managed a full programme
of performance tests ending with a qualifying simulation on a range of
softer tyres. He achieved good results on the soft tyre but unfortunately,
we were unable to improve with the supersoft or ultrasoft. This is something
we clearly need to understand. Lance completed the day with some further
performance tests giving our final information before we get to the first
race. Today brings to an end our 13-day pre-season testing session in Spain,
during which we have run eight full track days and two promotional events,
and given time in the car to Lance, Sergey and Robert. The weather has not
been ideal, but the team have made the best of the time and conditions
available. Considering this car had not even fired up just two weeks ago,
reliability has been very impressive with only two significant failures
losing track time. We have learnt a lot about the FW41 and completed all the
necessary commissioning processes to be fully prepared for the first race.
Well done to the team for the huge job done so far, and especially to our
three drivers who have pushed themselves and the team hard but without
incident, especially in some very tricky conditions.
Sergey Sirotkin: Today was definitely the best day of the last two weeks. We
managed quite a lot of laps in the morning and the afternoon. We completed
quite a good set-up evaluation as well, with slightly different tyre
compounds and fuel loads, so it was an interesting and nice day. The weather
was on our side which made the car much more consistent and driveable, which
we havenít really had until Wednesday. It was the second proper testing day
for me and the best one of them. There are still some issues, obviously.
Itís not all great and there are many little things we need to analyse and
try to learn from to get sorted for Australia, but at least we found out
what things are right and what things are not, which gave us a direction to
work in. Now we will do some homework and see where we will be in Australia.
Lance Stroll: Thatís the last day of testing done, next up is Australia.
Today felt pretty good, I think we did some good running. We have some bits
and pieces to sort out before Australia but I feel pretty good in the car.
