Abu Dhabi Grand Prix – Saturday 2nd November 2013. Yas Circuit, Abu Dhabi

Red Bull’s Mark Webber will start the 2013 Abu Dhabi Grand Prix from the pole position after qualifying fastest on the P Zero Yellow soft compound, which has been nominated together with the P Zero White medium this weekend.

Qualifying was held as usual in the afternoon and evening, with Q1 starting in daylight and Q3 finishing in darkness, under the lights. Webber’s 1m39.957s pole lap, the 13th of his career and his second of this season, mean that he equals the pole position record for an Australian, established by Jack Brabham. With Sebastian Vettel qualifying second, this was the fourth Red Bull one-two of the season.

With up to a second-and-a-half lap time difference between the two compounds, the strategy was an important consideration right from the start of Q1. Most drivers started on the medium compound, but both Red Bull drivers were straight out on the soft tyres and did not use the medium at all during qualifying. This then prompted the rest of the field to switch to the soft compound for the rest of Q1, with Mercedes driver Lewis Hamilton going quickest in the closing seconds.

The top 16 drivers went through to Q2 and were covered by just six-tenths of a second. They all used soft tyres throughout the session, at the end of which Mercedes was again quickest: this time with Nico Rosberg leading Hamilton.

The final top 10 all started Q3 on soft tyres. Webber set his pole lap right at the end of the session, with track temperature stabilising at 34 degrees. His time was over half a second faster than last year’s pole from Lewis Hamilton.

Red Bull also finished one-two in the final free practice session, during which all the drivers used both tyre compounds. Vettel led Webber, concluding the session with a qualifying simulation.

Pirelli’s motorsport director Paul Hembery said:

Two key factors shaped the strategy during qualifying: the big lap time difference between the two compounds and the high degree of track evolution, which meant that the fastest times were usually set at the end of each session once the most rubber had been laid down on the surface. As an extra factor, track temperature consistently fell with the sun going down during qualifying, which adds another challenge from a tyre engineering perspective. Most drivers expect a one-stop race tomorrow, but some may try something different. The options are open with the wear and degradation rates that we can see so far. While the soft tyre has a significant performance advantage, it’s also capable of consistent performance over a longer run. We’ve got the same tyre nomination as India, but the situation at this race is much less clear-cut, which means that strategy can make a real difference tomorrow.

The Pirelli mystery strategy predictor:

One stop is theoretically the quickest approach to the 55-lap Abu Dhabi Grand Prix, irrespective of starting on the soft or the medium compound. So, if starting on the soft, we would expect drivers to change to the medium on lap 12 and then go to the end. Or if starting on the medium, change to the soft on lap 43 and then go to the end.

The optimal two-stop strategy is: to start on the soft, change to the medium on lap nine, and a final stint on the medium from lap 32.
