Mercedes driver Valtteri Bottas claimed his first pole position of the season and the 1000th in Formula 1 history. He qualified just 0.02 seconds ahead of his team mate Lewis Hamilton, with both using the soft and the medium tyres during qualifying. The top five on the grid tomorrow will all start on the medium compound. FIA President Jean Todt presented Bottas with the Pirelli Pole Position Award for this landmark race.
The fastest strategy for the 56-lap Grand Prix is a one-stopper: start on red soft for 18 laps, then white hard to the end. The second-quickest approach is also a one-stopper, but this time starting on the yellow medium tyre for 19 laps before going on to the hard. Finally, there's a two-stopper - but this is clearly slower. Start on soft for 15 laps, then another soft stint for 15 laps, and finally hard to the finish. After an extremely warm Saturday, tomorrow's weather should be slightly cooler and similar to Friday, meaning that the teams can rely quite accurately on the data collected during free practice.
The frontrunners will be using what's theoretically only the second-fastest strategy, which could have an interesting effect.
The front-left tyre is the one that's most stressed around the track.
Today has been very warm, with track temperatures reaching 41 degrees, but in China conditions are famously variable. Expect warm weather for the race.
Alex Albon: the Toro Rosso driver didn't take part in qualifying after his crash in FP3 so will start from the pit lane tomorrow. Alfa Romeo's Antonio Giovinazzi also did not set a time in Q1 and so will start from the back. Both have a full allocation of tyres.
Mario Isola: "Temperatures were a bit warmer than often seen in China at this time of year, with track temperatures of more than 40 degrees centigrade - 15 degrees more than yesterday - and some wind as well. There were no real surprises during qualifying, with the tyres performing exactly as we anticipated and an interesting mix of strategies. As the top five will be using a strategy that is theoretically slightly slower than the drivers starting on the soft tyre, this could provide an extra element. However, starting on the medium also provides a bit more tactical flexibility. We'd expect there to be some degree of degradation on the soft tyre tomorrow, which will be one of the main factors influencing the timing of the pit stops."
