As the 2015 F1 Pre-Season tests come to an end, we’re left wondering if this year we’re not going to be still dancing to the same old tune as last year, with Mercedes showing amazing pace yet again.

On Saturday, Lewis Hamilton clocked in at 1:23.022s on the soft rubber despite the fact that it wasn’t a “particularly spectacular day” according to Lewis. He also added that “The track seems to have lost a bit of grip in the last few days so the feeling wasn’t as good. But I’m still glad we got some running done and I feel good in the car.”

Whether or not Hamilton could have matched his teammate’s extraordinary time from Friday (1:22.792s) if he had been more satisfied with the levels of grip he had, we’ll never know.

A quarter of a second behind Lewis was Brazilian Felipe Massa who drove the wheels of his Williams yet again, managing a quickest time of 1:23.262s, decades ahead of Ferrari’s Kimi Raikkonen who’s overall third best time was roughly 2 seconds off Massa’s pace.

McLaren-Honda were yet again the one of the teams failing to reach the 100 lap mark, with substitute driver Kevin Magnussen managing to do just 39 laps on his first outing in the 2015 McLaren thanks to an oil leak.

“This year’s car is really different to last year’s” said Magnussen. “It feels much more consistent; it’s more predictable and driver-friendly. It’s not fast enough yet, but it feels like a solid baseline, and there’s obviously still plenty more to come. I think McLaren-Honda should have a good car if they continue in this direction.”

We don’t know about that, since from the outside it looks like McLaren has taken a step back from what they had at the end of last year – when they managed better results than they did at the beginning of the season.

On Sunday, it was the Mercedes-powered Williams of Valtteri Bottas that went quickest at 1:23.063 on Pirelli’s supersoft tire, leaving him almost half a second clear of the chasing pack.

“It was a really good day and a great way to finish the test” stated Bottas. “One of the main points we have learnt is that the FW37 is very reliable. The car we are taking to Melbourne is very competitive and should make for an interesting start to the season.”

Sebastian Vettel was second fastest for Ferrari, while Sauber’s Felipe Nasr was the last man to get within one second of Bottas’s benchmark in third.

As for McLaren, they were yet again disrupted by technical problems, with Jenson Button only able to get out for two untimed laps in the morning, as a sensor problem meant his Honda power unit had to be removed. After the fix, Button pulled off 30 mediocre laps before calling it a day.

Force India’s Sergio Perez broke past 100 laps in what was his first day in the VJM08 racer – clocking in at 1:25.113, just ahead of Mercedes’ Nico Rosberg.

Teams will now have just under two weeks to get ready for the season opening 2015 Formula 1 Australian Grand Prix, with opening practice commencing at 12:30 local time on Friday, March 13.
