Formula One's traditional powerhouses came to the fore in Australia with Merc claiming the 1-2 in FP2 ahead of Ferrari...
Lewis Hamilton: "It really was a day of two halves today. While it was disappointing to not get any track time this morning, these little hiccups are going to happen with the new cars and we'll have to get used to that. It felt like I was on the back foot from there but then we got up to pace quite quickly in P2 and found the balance relatively fast. I feel quite comfortable in the car so overall it's a positive start but we need to look at the data now and understand where we are. We got a nice foundation for the weekend in the second session today so hopefully we can build on that in P3 tomorrow afternoon and then see where we are in qualifying."
Nico Rosberg: "It was so great to be back in the car today and I'm very pleased with the progress that we made. As always on a Friday, we don't really know where we are in terms of pace yet and how much fuel everyone else was running in comparison to our programme. It's definitely going to be very tough on fuel here, as we expected. The screen on my steering wheel shows the fuel target for each lap and we're going to have to be very disciplined in the race. It's a pretty good start for us overall and I'm looking forward to the rest of the weekend."
Fernando Alonso: "On the first Friday of the season, there's always a bit more tension. It's the start of a new championship and there is the feeling of general expectation to see how things we worked on during the winter are functioning. Overall, this was a positive day for us and even if there was an element of nervousness because of the complexity introduced by the new technical regulations, everything went well. The team did a super job and we had no problems. The track improved from the first session to the second, with more grip compared to the morning and there was also more wind. Running the soft tyre certainly helped, as the extra grip meant the times came down, but it's impossible to have a clear idea of how competitive we are, because as usual, Friday results don't mean much. To know more, we must wait until everyone is running in the same trim."
Kimi Raikkonen: "That was a pretty demanding day, because although we managed to complete our programme, it wasn't trouble-free. In the first session we lost a bit of time, but that didn't prevent us acquiring enough data to evaluate the overall handling of the car and the Pirelli compounds. This evening there will be a lot of work to do, especially to understand what didn't work and to try and improve for qualifying and the race."
Sebastian Vettel: "In a way it's a relief today, the fact that we were running, we didn't have any problems, the balance was good and the performance looked alright. In the end Friday times are not worth a lot, but it's better to be close to the top rather than somewhere towards the back, so I'm very happy with that. We will do what we can to prepare for tomorrow and Sunday, but let's see where we are then - the most important thing is that we finish."
Daniel Ricciardo: "I knew the guys were doing everything they could since testing but still, we didn't expect to do that many laps today, so I'm really happy and pleased for them. I think we have to be pretty positive with where we ended up today. We expected Mercedes to be quickest, but we were within a second of them today so that's a lot better than we thought. Let's see if it's the same story after qualifying tomorrow, but for today we're pleased."
Jenson Button: "I always enjoy this circuit - it's quite bumpy and there's no room for error, which always makes it fun! In all honesty, these cars work better around here than I'd imagined, but Sunday's race will be very different. The long runs weren't as much fun as I'd hoped they'd be, because you need to save a lot of fuel. And that's such a different way of driving - you're lifting off very early, and there's lots of lift-and-coasting around the lap. On low fuel, however, it's really fun to drive.
"Our car balance isn't quite there yet - we're still struggling a little in the high-speed corners. In the low-speed corners, we're looking reasonable, and all our electronics are working well. I don't think our outright pace is quite as good as it looks on the time sheets, but we've got a good understanding of the car and overall I'd say we're looking okay."
Kevin Magnussen: "For me, today was about getting used to everything; taking it step by step, and making sure I was moving forwards and learning all the time. I've watched Formula One cars on this circuit on TV for many years, so it's strange to be driving here at last. But it was a good feeling to be out there on the track - I really enjoyed it.
"There's definitely an element of learning for me here this weekend, so it's good to have Jenson alongside me. He's so experienced, and of course he's very strong around here. I can learn a lot from him. The rest of the weekend is going to be really interesting.
"Lastly, I'm happy that we've got a lot of good data to go through. So now I've got to sit down and work hard with my engineers and the rest of the team to develop the car ahead of qualifying tomorrow. We think we know where to take the car from here, but as I say there's still plenty of work for us to do."
