♦ With temperatures already at 30 degrees C. when the race started, managing the tyres was a major part of the race strategy for the Mercedes-AMG drivers. It was evident from the beginning laps as they moderated lap times.

♦ Unlike his advantageous situation at Silverstone in the previous round, Max Verstappen found his tyres (especially the rear ones) to be less than satisfactory at Catalunya.

♦ After 22 laps, the drivers were struggling with the tyres and heading for the pits to get fresh sets. 3 of them held out till over 30 laps.

♦ At the halfway mark, while Hamilton kept a 5.5-second gap from Verstappen, the action was closer in the midfield between drivers like Alexander Albon, Pierre Gasly, Charles Leclerc and Land Norris.

♦ The engine of Leclerc’s Ferrari cut suddenly on lap 40, causing a spin and stall. He managed to get it restarted and limped to the pits, his race over.

♦ It may have been blistering hot but as 20 laps remained, the possibility of rain grew stronger. That was something unexpected since it had not rained at a Spanish GP in 21 years.

♦ With 13 laps left to go, the Ferrari team decided – and Vettel agreed – that he would not change tyres and aim to finish on the very old set he had. But he found it hard to hold off other cars and slipped from fifth to seventh.

♦ With 4 laps remaining, Hamilton had a comfortable 17-second gap from Verstappen, who had to watch out for Valtteri Bottas making a bid to end with a Mercedes-AMG 1-2.

♦ With one lap remaining, Bottas changed his tyres with the aim of going for the fastest lap and managed to pick up an extra point.
