Nico Rosberg set the pace for Mercedes on the second day of the final pre-season test in Barcelona, as McLaren racked up the mileage.
Rosberg dominated the timesheets with a lap of 1:22.792 – the best time set at the Circuit de Catalunya during testing – recorded on a set of the soft Pirelli tyres in the late afternoon.
The 2014 runner-up ended the day with 106 laps on the board, and 1.2 seconds clear of Valtteri Bottas at the top of the leaderboard as Mercedes flexed its muscle.
Bottas completed 90 laps for Williams on route to second, with a best lap of 1:23.995 on the medium tyres, ahead of Felipe Nasr, who topped the morning session at the wheel of the soft Pirelli shod Sauber.
Nasr racked up 141 laps, two shy of Sebastian Vettel’s total of 143 for the day – the best of any driver – in fourth in the Ferrari.
Friday marked McLaren’s most productive day of the entire pre-season as Jenson Button completed 101 laps before a late issue caused the Honda-powered MP4-30 to stop on track.
Pastor Maldonado prompted a late red flag with a stoppage at the entry to the pit lane, but ended the day sixth for Lotus, with 140 laps on the board.
Max Verstappen racked up 139 laps on another profitable day for Toro Rosso before a late electrical issue forced the team to cut short its test programme.
Daniil Kvyat, who caused a red flag with a stoppage at turn 1 on the afternoon was eighth on a low-key day for Red Bull, while Nico Hulkenberg completed 77 laps at the wheel of the new Force India after appearing late in the morning session.
