Rosberg keeps Mercedes on top in Austria test

Nico Rosberg went quickest during the second day of Formula 1 testing at the Red Bull Ring, keeping Mercedes on top of the timesheets for a second day in succession.

After rain had curtailed a large of portion of Tuesday's running, dry conditions prevailed on Wednesday, allowing the teams plenty of time to work through their programmes.

It was Valtteri Bottas who was in control of much of the morning, setting a best time of 1:11.965 on soft tyres before working his way down to a 1:10.495 on supersofts.

That benchmark stood until a rapid run early in the afternoon by Rosberg, whose best time of 1:09.113 was enough to top the session by over eight tenths of a second.

Esteban Gutierrez moved Ferrari up to second relatively late on, less than a tenth ahead of Bottas, whose Williams team once again completed the least amount of laps on 79.

At the opposite end of the spectrum was DTM champion Marco Wittmann, who set the fourth best time of the day for Toro Rosso in his first day behind the wheel of an F1 car while recording the most laps of anyone with 158.

Pascal Wehrlein, yesterday's pacesetter for Mercedes, was fifth for Force India, putting some more mileage on the team's revised B-spec car, ahead of Lotus driver Jolyon Palmer, who came to a stop on track with just a couple of minutes of the session remaining.

Fernando Alonso managed 104 laps for McLaren-Honda, having swapped days with the team's tester Stoffel Vandoorne following his Austrian GP crash in order to be able to trial more upgrades, and was seventh quickest, 1.6 seconds off the pace.

Propping up the timesheets were Daniel Ricciardo, who caused a red flag late on when his Red Bull ground to a halt at the pitlane entry because of a brake problem, and Felipe Nasr, who was the second most productive driver of the session for Sauber on 138 laps.
