The Formula 1 teams came into action with their new cars for the first time during the test days in Barcelona. Little can be said about the balance of power, but it is clear which teams were the most productive during the first winter test. In that respect Ferrari set the tone.
Mercedes closed the first winter test as the fastest, but did so with the softest tire. Both Lewis Hamilton and George Russell drove on the C5 compound. This in contrast to Max Verstappen, who set his fastest time on the medium (C3) tire. Sergio Perez drove his fastest time on the C4 tire.
Below is a total overview of the fastest times driven during the test days in Barcelona. It also looks at the top three times per tire type. It is notable that the Ferrari drivers are particularly fast on the medium tire, as is Max Verstappen.
We also list the total number of laps driven per team, per driver and per engine supplier. For the engine suppliers the total number of laps is also divided by the number of teams driving with the same engines, which gives a more divided picture.
