Mercedes set the fastest time of anybody at Barcelona, they brought their final package to the final test, whilst Red Bull, Ferrari and McLaren are bringing further updates for Australia.
Can't wait for the weekend, the Red Bull's look imperious again with the Ferrari's not too far behind, although there are rumours Red Bull have not run with less than 80kg of fuel in any test. Frightening if true.
McLaren have looked piss poor so far, but they've designed a whole new concept in comparison to the evolutions of last years cars by Red Bull and Ferrari. It will take them a while to understand and get every last tenth out of what they have. I expect them to be competitive, but not fighting for the win this weekend. Their biggest worry is reliability, they've not completed a full race simulation in any of the tests.
Toro Rosso look promising this season and I'm excited to see the young pairing at Sauber.
