The winter wait is over as F1 cars and MotoGP bikes hit the track today for their first test sessions. New cars and drivers, and some old faces for both, so it is going to be hard to make anything of this first test. Alonso and Vettel both near the top of the timesheet, with Hulkenburg in the Force India putting in some surprising times to be right there with them.  Just showing Williams they should not have let him go? The Lotus Renault and Williams have followed Red Bull with the pull rod rear suspension, but the biggest surprise so far is the lack of exhaust outlets on the Renault. They obviously have them, they just do not come out of the top or the sides, so must be underneath. This is the team that promised to be "at the brave end of brave," and it seems they are trying something here. At the end of last season, when we had the diffusers, most teams were feeding the exhaust gas out through them to increase downforce, so we can only presume they are doing something with this gas flow to generate downforce under the car. I read an article a few years ago that said an F1 engine is just a huge air pump, so the volume of gas coming out of the exhaust must be massive. In fact at 18,000 rpm that is 2.4 liters by 18,000, or if my math is correct, 43,200 liters per minute. Imagine if your local gas pump ran at that speed?

At the other end of the timesheet Rosberg is slowest, then Barrichello, with the HRT quicker, go figure.

Over in Sepang Casey Stoner is fastest on day one 0.4 seconds faster than Lorenzo. Did not take Casey long to adjust to the Honda. Now Valentino is down in 12th trying to find a position on the Ducati that is comfortable. Someone suggested he is still sand bagging, but team mate Hayden is behind him, and what use is it to sand bag? Can you really set up the bike if you are running around off the pace? And I would have thought that the "head games" would dictate that you would want to put your stamp of authority on from the beginning? Maybe someone out there can enlighten me? Good to see the Suzuki somewhere on the pace unlike last year, and Ben Spies going OK, but then so is Colin Edwards on the second team Yamaha.

In other news, Bernie is not talking about bribes on the advice of his lawyers, and Mark Webber says he is up for another crack at the title and I'm sure he is given how close he was last year. What Bernie is talking about is new races, "If we have some new races, some others will fall out — we don’t need Australia, for instance." Nice one Bernie.
