Vettel maximizes Pirellis in Shanghai practice

 The teams used free practice to try out different set-ups, with some drivers running new parts and others carrying out long runs in order to acquire information to formulate race strategies. The winner of the first two grands prix, Red Bull’s Sebastian Vettel, was straight on the pace from the very beginning, despite a track that was dusty and dirty, setting fastest time in both the morning and afternoon sessions.

Vettel’s fastest time in the morning was 1m38.739s, six-tenths of a second quicker than his team mate Mark Webber, who was runner-up. All the drivers used Pirelli’s hard tires, benefitting from the extra set that they had been given in the morning. In the afternoon, Vettel improved his time to 1m37.688s, this time using the soft tire. Lewis Hamilton, also on the soft tire, was second fastest for McLaren, 0.166s slower than Vettel.

The afternoon session ran in identical temperatures of 81 degrees ambient and 86 degrees Fahrenheit on track, with Vettel setting a fastest time of 1m37.688. Williams driver Pastor Maldonado was the first driver to switch to soft tires, 23 minutes into the afternoon session, and was instantly quickest, confirming an expected difference of 1.5 to 2.0 seconds per lap between the soft and the hard tires.

In total the drivers completed 1.098 laps of the 5.451-kilometer (3.387 mile) circuit, 458 laps in the first free practice session and 640 laps in the afternoon.

“We’ve been very encouraged by our first day of running in China, which like nearly every one of the circuits this year is entirely new to us, Pirelli’s Motorsport Director Paul Hembery commented. “Although today has been warm, degradation is a lot less than we saw in Malaysia, so I’m expecting to have two pit stops per car on race day, similar to Australia. We’ve also seen a lot fewer ‘marbles’ – deposits of rubber, with the shape and consistency of toffee, left by the tires on the track as they degrade – and that should be the case during the race too as we are expecting fewer pit stops in the normal course of events. In terms of wear rate, there’s a good five to six lap difference between the soft and the hard, which opens up various different possibilities in terms of strategy. The weather seems uncertain tomorrow, which is sure to add another level of intrigue to what is already shaping up to be a thrilling weekend.”
