Both Renault and Sauber are launching their 2010 cars on the same day - just before the first pre-season test gets underway in Valencia. We're interested in both cars, naturally, and both teams also have a surprise to offer in terms of the livery as well. Peter Sauber has managed to buy back his team from the clutches of BMW, so he will want to put his own mark on things, I'm sure.

Sauber will have their two confirmed drivers at the launch, in the form of Kamui Kobayashi and Pedro de la Rosa. They make an odd pairing, so it will be interesting to see how they get on. Plus, de la Rosa will be making his return to a race seat, and will probably be pretty happy to get things going.

We haven't had two teams launch on the same day this year, so it will be interesting to see who gets the majority of the headlines. We'll be watching the news with a keen eye, and looking out for pictures and any gems from Twitter to keep you updated.
