Nico Rosberg’s
pole position for the Brazilian Grand Prix, using the P Zero Yellow soft
tyres, was the fastest-ever pole lap ever seen in the 41-year history of
Interlagos. Rosberg set a fastest time of 1m10.023s in the final qualifying
session, beating Ruben Barrichello’s pole record of 1m10.646s from 2004.
Rosberg’s time was even close to the all-time fastest lap of Interlagos,
which was set by Barrichello in first qualifying the same year: 1m09.822s.
Mercedes also equalled Red Bull’s record for 18 pole positions in one
season, while Rosberg claimed the pole position trophy for this year.
With a good amount of grip and high track evolution on the newly laid
asphalt in Brazil, the times became rapidly faster – with the pole position
record beaten already in Q1. All the drivers used the softer compound in an
attempt to get through to Q2, with the Williams drivers the last to change
from the medium. On average, the difference between the two compounds
remained between 0.8 to 1.0 seconds, depending on the car.
Despite the widespread
predictions of rain, and an overnight thunderstorm, qualifying remained dry
with the session starting in 27 degrees centigrade ambient and 39 degrees of
track temperature. However, rain showers are still expected for the race
tomorrow, which will undoubtedly complicate the strategy, especially as the
historical safety car probability is already 60%.
Normally a three-stop strategy would be quickest, but with a short track of
just 4.309 kilometres, traffic will be an issue and this will affect each
team’s choice of tactics. Different strategies were already in evidence
today, with Toro Rosso’s Daniil Kvyat electing not to run at all in Q2 and
save tyres, as a penalty means that he will be starting from the back in any
case. The Ferrari drivers were the only ones to complete just one run in Q3,
also saving a set of tyres. As was the case in the United States last week,
just four cars were eliminated in Q1 and four more in Q2.
Rosberg also continued his monopoly of the free practice sessions in Brazil
by setting the fastest time in FP3 this morning, using the medium tyre.
Pirelli’s motorsport director Paul Hembery said: “We had cooler
conditions today, which suited our nominated tyres better than the unusually
hot track temperatures that we saw yesterday. Qualifying was an extremely
tight battle, with the threat of rain providing an extra edge, but that
threat if anything will intensify tomorrow. Obviously this will have a big
effect on the strategy, but if it stays dry the quickest theoretical
strategy is a three-stopper, although we would expect most teams to try a
two-stopper in order to avoid getting caught up in traffic. After an
interrupted day yesterday all the teams managed to collect more data today,
with the top two qualifiers separated by just three-hundredths of a second.
We’ve seen the fastest-ever pole lap of Interlagos today, which underlines
the way that the cars and the tyres have developed over the last 10 years.”
The Pirelli strategy predictor:
A three-stop strategy is theoretically the fastest for the 71-lap race at
Interlagos; the track with the second-shortest lap of the year after Monaco.
However, this means that traffic is a real issue – so this strategy is a
risk for anything other than the very fastest cars. The fastest theoretical
strategy is: a short stint on soft before changing to medium; medium again
on lap 21 and a final stint on the medium from lap 46. A two-stop strategy
is almost as quick and carries a lot smaller risk of hold-ups: start on
soft, change to medium on lap 13, then medium again on lap 42. Those
choosing to start on the medium have another two-stop option: change to the
medium again on lap 29, then try to make up time at the end of the race by
switching to soft on lap 58. Most teams will probably start with the idea of
doing a two-stop strategy, but maintain the flexibility to do a
three-stopper if necessary. If it rains, as seems highly likely, then the
whole strategy changes completely. |
