Most fastest times were set on the softest C5 tyres. Pirelli estimated in the previous year that the performance gap between each tyre compound was around 0.6-0.7 s, although this varied based on numerous factors. Bottas' fastest time was three tenths slower than his pole position time from the 2019 Spanish Grand Prix at the same circuit. As of February 2020, his Q2 and Q3 laps from the 2019 Grand Prix and his fastest lap in 2020 testing are the three fastest laps ever at the circuit in its current configuration, and the only three laps under 1:16.000 s.
