Sebastian Vettel remains at the timesheets on Day 2 of the pre-season test at Barcelona

At the second pre-season F1 test of the 2016 season, Ferrari driver Sebastian Vettel was quickest ahead of Red Bull driver Daniel Ricciardo and Force India driver Sergio Perez.

Vettel topped another day of winter testing with Pirelli’s new ultra-soft compound on a busy day which saw eight of the 11 drivers surpass 100 laps. Vettel put in a lap time of 1:22.810 ahead of Daniel Ricciardo who had an encouraging day in second place and finished 0.7 seconds behind Vettel after bolting on the purple-striped ultra-soft tyre, which is new for 2016, for the first time.

The tyre is unlikely to be used anywhere other than street circuits this season but Vettel and Red Bull, who put the compound on Ricciardo, were the first to roll them out. The only blemish for Vettel was a stoppage five minutes from the end of the session when he pulled up at Turn 3 which prematurely ending the day’s session.

Sergio Perez finished in third place which was set on the super-soft tyre and ticked off 101 laps in the Force India. Nico Rosberg finished in fourth place on a day which saw Mercedes stick exclusively to the medium tyre.

The Mercedes team completed the all 12 days of winter testing last year without using the softest compound and showed no sign of attempting a quick lap throughout the session, with the team clearly focused on longer runs. But Mercedes did manage to complete a race distance before lunch before Rosberg exceeded Hamilton’s Monday tally, ending on 172 — over 800km — by the time the chequered flag fell.

The fact Mercedes was even executing live pit stop practice suggests the world champions have made a lot of progress in working through its testing programme.

Sauber’s Marcus Ericsson finished in fifth place after completing 108 laps in the 2015-spec Sauber ahead of Haas driver Esteban Gutierrez, who finished the day in sixth place with 79 laps to his name. Valtteri Bottas had a solid but unspectacular day for Williams by ending the day in seventh place with 134 laps overall ahead of handing the car over to Felipe Massa on Wednesday.

Manor driver Pascal Wehrlein ended the day in eighth place with 71 laps completed and finished ahead of Fernando Alonso in ninth place in the McLaren MP4-30 but completed an impressive 119 laps. Honda managed just 380 in 12 days of testing last year so it will have been more valuable mileage for the Japanese manufacturer on a day its reshuffled F1 team was in the news.

But it is unlikely McLaren is chasing lap times at this stage with mileage and reliability the focus and the team will be encouraged by the first two days of testing.

However, there were more problems for Jolyon Palmer and Renault who finished the day in tenth place after Palmer stopped in the afternoon session with 47 laps to his name with what the team confirmed was a power unit issue. The stoppage came after his “challenging” opening day with the car and means he finishes his first two days in the car — 50% of his driving time before Melbourne — with just 79 laps completed.

The other red flag of the day was caused by Max Verstappen’s stoppage in the hour before lunch after gearbox trouble. The plain blue Toro Rosso, powered by Ferrari’s 2015 engine, stopped at Turn 13, but eventually returned to the track and completed 113 laps and finished in eleventh place.
