for full F1 testing [Sunday 1am] lap times
Nico Rosberg set the pace on the first morning of F1 testing in Jerez, the Mercedes driver completing a race distance and dipping below last year's best time.
Having pulled the covers off the W06 in the morning, Rosberg was the first driver on track in the title-defending car and quickly got to work, covering 66 laps over the opening four hours and stopping the clock at 1min 23.106secs on his best circulation.
The German is already two tenths quicker than the fastest time from four days of Jerez testing a year ago – set by Kevin Magnussen -, though weather was poorer 12 months ago and it was the first outing for the new generation cars.
Having opted not to 'launch' its car, Red Bull pulled out of the garage and caused a surprise with an unusual 'camouflage' livery on its RB11, though it stresses it will just be for the test. Daniel Ricciardo was second fastest, 1.5secs behind Rosberg.
A brief spin early on aside, Marcus Ericsson put in some good mileage on the Sauber C34 and was just a tenth slower than Ricciardo at the four-hour mark, while Sebastian Vettel has completed just eight laps in Ferrari colours despite being one of the first to set times.
Similarly, Fernando Alonso has kept mileage to a relative minimum in the McLaren-Honda, the Spaniard emerging relatively late and completing 6 slow laps before returning to the pits. Williams were also late on track with the FW37, but Valtteri Bottas was getting up to speed by lunchtime.
As yet, no driver has stopped on track with technical issues, though Ericsson's spin did cause a brief red flag.
Meanwhile, Lotus will not venture on track today as the E23 Hybrid has not arrived in Jerez.
