Logo needed for motorsport series

Auto GP

Auto GP is a brand new open wheel championship, based in Europe and contested with single seater cars.
Our series placement is below Formula 1 and GP2, but above anything else that races in Europe thanks to a 550 bhp car. You can find an image of the car here http://img337.imageshack.us/img337/6493/cart.jpg

We aim to gain brand awareness in the motor racing business, as well as an image that can be immediately recognised by car or racing enthusiasts which, we would say, could be males, age 15 to 55.

We are looking for a logo to represent Auto GP (GP means Grand Prix)

We are oriented on a square logo, with the name of the series clearly readable when it's used, as an example, as a Facebook avatar.

We would like to spread our core values: professionalism, reliability, combined with a fast car.

We think our logo should express a right balance between aggressiveness, dynamism and professionalism. If we’d have to sum up all that in an adjective we would say “sharp”.

For the reasons expressed before, a cartoonish style isn’t in our thoughts, but feel free to insert stylized elements in the logo. We aren’t saying that that’s exactly what we want, but feel free to try different solutions.

Use any colour combination you like, for the moment.

Please do not use any stock images or clip art in the logo

We need the logo in a vector .eps file, in a CMYK .ai file, and in .jpg and layered .psd format.

We will provide contious feedback during the contest, thanks in advance for your attention.
