IMHO, the A1GP and GP2 chassis' don't look too hot, however, -IF- OWRS decided that they want to go with a NA engine in a year or two then I would like this chassis to replace the current one....
SF01
That being said, I have a good feeling that the Three Amigos are going to stick with the Turbos, therefor the current chassis won't look that much different. They will be thinner looking since KK mentioned recently that they're going to shed around 200 lbs. off the car.
