Reigning World Champion Lewis Hamilton apologised to his Mercedes team after he crashed out of Friday's second practice session for the Hungarian Grand Prix.
Hamilton led the way in the second practice session before he went off at Turn 11 and suffered a 12G side impact, though was able to recover his car to the pit lane.
Hamilton was ruled out of the remainder of the session as Mercedes conducted checks on his car and ultimately slipped back to fifth place, as Nico Rosberg led the way.
"Obviously, not the greatest session for me," he said.
"My apologies to the crew for all the hard work they have ahead to strip the car and get it back together.
"Fortunately, I got a good feel for it in the few laps that I did have and the pace is clearly there, so hopefully tomorrow I can make up for the time lost today during the morning session and come back strongly in qualifying."
Rosberg was confident after he topped the session by over half a second.
"An impressive day for us, performance-wise," he commented.
"Of course, that doesn’t necessarily mean we’ll be in quite such a strong position tomorrow – but for now it’s very positive.
"I’m feeling great out there and the car is very quick, so a good start to the weekend overall. We got everything done in terms of qualifying and race simulation work and it’s all looking very good."
