Bahrain Grand Prix will open this Sunday and the Formula One drivers had their first practice session on Friday.

Here are some photos of Red Bull Racing team, who are in collaboration with Infiniti.

“We did a lot of running today, so that's good. Regarding set-up, I think we got the answers in China that we were looking for and that's helped us here. We now need to see where we are against what everyone else did today. It's very hot here, so the tires are suffering a little as a result, but it's the same for all teams. I think others are the favorites this weekend, but we are focusing on ourselves and pushing hard. We made a step forward, but we see where we are tomorrow,” said Sebastian Vettel on the Infiniti website Friday.

“It was quite challenging out on track, trying to get everything together. The tires were a bit of a surprise for everybody in terms of how they are behaving, they're losing their grip pretty quick, but that's the same for everybody. There are some quick cars out there – of course we don't know which fuel loads people were running, but it looks pretty tight again. Tires will play a big role on Sunday in the race,” said Mark Webber.
