Australia Friday quotes: Red Bull

"I didn't get many laps in during the first session, but the second was a lot better. We completed more laps and tried both types of tyres, so we've got some good stuff to go through tonight. It was quite interesting to see how low the sun was through the trees towards the end of the second session, it was good to run with that to get used to it for Sunday."

Sebastian Vettel - 8th: "We had a bad session in this morning's practice and didn't get too much running, due to a hydraulics problem. In the afternoon we were able to get some laps in, but unfortunately I made a stupid mistake towards the end of the practice, so we couldn't run through our programme.

"Nevertheless, it's looking alright with what we've done compared to the time we had on the circuit, so let's see how we go tomorrow. Like always on Fridays, it's a bit difficult to interpret everyone's lap times, but I think we can be happy."

Christian Horner, Team Principal: "After the off-track activities of the last couple of days, it was good to get the weekend under way. There were a couple of issues in the first session - a hydraulics leak with Sebastian and a driveshaft problem with Mark limited our run-time.

"In the second session both drivers showed good pace and we worked through our programme. Unfortunately Sebastian had a small off, which ended his day early, but both drivers seem comfortable in the car and their pace was respectable."
