There was a high degree of track evolution on the Yas Marina circuit, especially during the FP1 session. This meant that a number of drivers set faster times on a harder compound compared to the softer ones that they ran previously, as conditions improved. However, by the late afternoon - when FP2 was run, at a similar time to qualifying and the race - track conditions had stabilised, meaning that representative times were set on each compound.
The FP2 session was held from 17:00, with track temperatures falling throughout the session by three degrees, and more than 10 degrees compared to FP1. As expected, the ultrasoft proved to be ultimately quickest, setting the fastest time of the day with Lewis Hamilton for Mercedes: 1m40.861s, more than a second quicker than last year's FP2 time (set on supersoft).
The smooth nature of the surface and the varying track conditions meant that the speed differentials between the different compounds was reasonably small, compared to other tracks. So far, around 0.8 seconds separate the supersoft from the ultrasoft. Teams completed both race and qualifying simulations, with the top two Mercedes separated by just 0.079s.
Paul Hembery: "As we expected, wear and degradation is reasonably high on the softest compounds, due to the high longitudinal acceleration and braking demands of this track. However, the pattern depends very much on the state of the track, which has been changing all day due to normal evolution and also falling temperatures in FP2. As a result, drivers are chasing a moving target when it comes to defining set-up and strategy, which adds an extra element to the challenge imposed by the championship finale. Already we have seen some of the run plans today influenced by the pre-event tyre choices from each driver, giving an insight into individual strategies."
