The first pre-season test of 2010 kicks off at Valencia today which means it is the first chance to see how the different cars perform on track.

On the weekend, BMW Sauber and Renault launched their 2010 machines. The BMW Sauber C29, despite the name of the team, is powered by a Ferrari engine and as Drivers Pedro de la Rosa and Kamui Kobayashi pulled back the covers at the Valencia circuit a car with a very high nose and a long shark fin was revealed.

Shark fins seem to be popular this year as Renault’s new car is also sporting one. The R30, to be piloted by Robert Kubica and Russian rookie Vitaly Petrov, was also unveiled on Sunday. With the departure of sponsor ING, Renault has returned to their historic yellow and black livery which gave the Renault RS01 the nickname ‘Yellow Teapot’.

On Monday morning, Toro Rosso revealed their first car as a fully independent constructor. Team boss Franz Tost said:

After four years of working in collaboration with Red Bull Technology, the STR5 is the first car that is one hundred percent down to our own endeavours.

Although the car looks quite similar to last year’s STR4, it has been designed to take full advantage of running a double-diffuser.

Mercedes GP also revealed their W01 in the pit lane ahead of today’s test (the car presented at the team’s launch last week was a repainted Brawn BGP01). It is a nice looking car with a graceful, swooping nose and a small shark fin engine cover.

Williams are foregoing an official ‘launch’ and will reveal their Cosworth-powered FW32 when it rolls out of the garage for it’s installation lap.

Today’s launch at the Mercedes-Benz Museum in Stuttgart was a team and livery launch – not, unfortunately, the launch of their 2010 car. For that, we will have to wait until 1 February when the MGP W01 will make its track debut at Valencia.

Nevertheless even without a new car on display the first (sort-of) launch of the new season was still enough to bring down the Mercedes GP website. McLaren is planning to live stream the launch of their MP-25 at Vodafone UK’s headquarters in Newbury on Friday January 29. I hope their servers are up to it…

Still, it was a chance to see what the new car’s paint will look like and also for Michael to say how excited he is to be driving for Mercedes-Benz again and how it is a “dream come true” for Nico. It will be very interesting to watch the dynamic between these two drivers once they get on track.

The new livery looks great: Mercedes’s traditional silver with flashes of green for new sponsor Petronas. On the nose and other parts of the car, the silver paint has been removed to allow traces of black carbon fibre show through. This is a nice touch – a reminder of the first Silver Arrow of 1934.

There is a (probably apocryphal) story about how the 1934 Mercedes Silver Arrows racing cars got their colour.  Before the introduction of sponsorship, racing cars had always been painted in the traditional colour for their country; Britain was British Racing Green, France was French Blue and Italy was, of course, Rosso Corsa.  German cars were painted White.

From 1934 onwards a maximum weight limit of 750kg was introduced and Mercedes-Benz found that their W25 weighed 751kg.  After puzzling over what they could do to lose weight, racing manager Alfred Neubauer came up with the idea of scraping off all the paint to leave the silver aluminium exposed.  This supposedly saved the 1kg required and the Silver Arrows were born.
