World Champion Lewis Hamilton says he is not bothered by Mercedes' absence from the top of the time sheets, as testing reached its halfway mark at the Circuit de Barcelona-Catalunya on Friday.
Hamilton, who sat out most of Thursday's running due to a fever, took over from team-mate Nico Rosberg for the afternoon session in Spain and registered the fifth quickest time after racking up 89 laps.
Mercedes has yet to finish a day of testing on top of the times, but Hamilton says he is not concerned by the squad's current position.
"I've felt better but I miss driving so I wanted to get in the car," he said. "It's been good today to get out there and get some laps in. I'm not sure where we stand compared to the others.
"The first test was just about completing loads of laps and today was the same, so I've not really started dialing the car into how I'd like to perfect it. Quick laps are for Saturday in qualifying.
"But it feels good - similar to last year but better. We're just focused on our own job - getting lots and lots of miles on the car, proving everything out and making the most of the time we have before the season starts.
"We've not been without a few problems here and there but I've seen the team working away to iron out any creases and it's just amazing to watch. As long as we keep moving forwards that's what matters most and we're focused on doing that."
