Mercedes driver Lewis Hamilton
has taken another pole position on home territory, using the soft tyre to
set a time that was the fastest ever seen on the current 5.891-kilometre
Silverstone configuration.
Conditions were cool and overcast for qualifying, with ambient and track
temperatures that reached only 22 and 27 degrees centigrade. During free
practice in the morning there was some light rain, with both Cinturato
intermediates and full wets seen on a damp track, which eventually dried
enough for slicks to be used.
The soft tyre was used right from the beginning of Q1 for nearly all the
drivers: the softest compound available, seen for the first time at the
high-energy Silverstone circuit.
A two-stop strategy is set to be the optimal choice for the race tomorrow if
conditions remain dry – which is far from guaranteed, using the soft and the
medium tyre. As is often the case, there are also other strategy
permutations that could help to boost track position.
Hamilton already broke the absolute lap record at the end of Q2 on the soft
tyre, which is the compound that the top 10 will all start with tomorrow. He
wasn’t quite as quick in the final Q3 shoot-out, setting a pole time of
1m29.287, which was still a full three seconds faster than last year’s
equivalent.
Paul Hembery, Pirelli motorsport director: “A day of mixed conditions
again, which is typical of Silverstone and could well be the case again
tomorrow. This is why the data gathered in all these different conditions up
to now is likely to be very useful. We’ve seen some absolutely stunning pace
with the soft compound in particular, while the medium looks like it’s going
to be the favoured race tyre, using a two-stop strategy.”
How the tyres behaved today:
Hard: only used in the first part of Q1 by Force India, not seen for the
rest of qualifying.
Medium: Seen in FP3 and hardly at all in qualifying, but will be the
favoured race tyre.
Soft: the most popular choice in qualifying used from start to finish by
almost everybody.
Possible race strategies and maximum laps:
Pirelli recommends that the following numbers of laps are not exceeded on
each compound:
Hard* = 26 laps
Medium = 28 laps
Soft = 15 laps
*The hard compound experienced some graining, which is why the useful life
of this tyre
is predicted to be less than that of the medium.
On this basis, the optimal pit-stop strategies predicted by Pirelli are
as follows:
QUICKEST
Two-stopper: two stints on soft of 12 laps each + one 28-lap stint on medium
SECOND-QUICKEST
Three-stopper: three stints on soft of 12 laps each + one 16-lap stint on
medium
THIRD-QUICKEST
Two-stopper: one 12-lap stint on soft + one 14-lap stint on new soft + one
26-lap stint on
hard
SLOWEST
Two-stopper: one stint on soft of 12 laps + two 20-lap stints on medium
Different permutations of compound usage within each strategy are possible.
These indications do not represent or constitute a guaranteed minimum number
of laps for each compound. It is the responsibility of each team to define
its own race strategies based on its own wear data.. |
