Sainz fastest on day 6 of pre-season F1 testing

F1 Test, Barcelona, Circuit de Catalunya

Carlos Sainz's time from the morning session remained fastest throughout the day as nobody came close to beating the best time so far in testing. Sergio Perez and Sebastian Vettel ended the day second and third quickest.

McLaren also had a really productive day, with 130 laps on the Spaniard's their tally, as much as Kubica managed in the Williams FW42.

Mercedes however were most productive team. As usual, the team shared duties between its two racing drivers, completing an impressive total of 175 laps. That'll be a happy evening for the team, after they openly admitted their lack of running on Tuesday meant a delay in evaluating their upgraded aero package.

For Ferrari, the day was busy too, but less so on the track, as the SF90 wasn't seen back on the circuit after Vettel crash at 11:00 until late in the afternoon, allowing Leclerc to do just a few control laps before the end of the session.

Similarly, Racing Point's day of testing wasn't going to be much to write about, until a late flyer on C4 tyres shot him up into second on the timing sheet.

Verstappen's day wasn't perfect either. Though he ended the morning session third fastest, the afternoon session brought some antics due to a gearbox issue that caused a stoppage as he drove out of the pitlane. He also spun his Red Bull RB15 at Turn 3, but managed to get going again without the need for a recovery truck. The Dutchman was still the first driver to complete 100 laps, ending his day with 128 tours around Circuit de Catalunya.

Testing continued on Thursday and Friday for the final two days before teams set off to Melbourne.
