Not one team consistently had problems throughout the two weeks in Barcelona.
Mercedes had an 'off-day' with an engine issue, but that didn't crop up in the final day of winter testing.
Fastest times
As expected, the fastest times were mostly driven on the third and final day of the test week. The fastest time of the second test week went to Mercedes driver
Valtteri Bottas. Max Verstappen follows the Finn in second place. He was just a little bit faster than his old teammate
Daniel Ricciardo. The Renault seems to be a competitive car this year because
Esteban Ocon also set a fast time with the RS20.
Most laps
Ferrari went under the radar. We did not see many fast times from the Scuderia, only Leclerc squeezed out a reasonable lap on the final test day. The team did by far the most laps on the Barcelona Circuit. A striking second place went to Williams. They were able to complete a total of 413 laps in test week two.
