These are fascinating moments as we see how the cars adjust to a completely different layout to the one they experienced for testing and opening Grand Prix of the season in Bahrain.

After Red Bull dominated in Sakhir, the likes of Ferrari, Mercedes and Aston Martin are all hoping to be closer to the reigning constructors' champions this weekend.

It also must be remembered that this first session is somewhat of a feeling out process before we see the cars under the lights later, in conditions that are more representative of those we'll have in qualifying and the race.
