I'm not sure whether this is the right forum or not, but since it's motorsport related. You can download a copy of the V8 Supercars Race Driver 2 Demo at http://www.ausgamers.com
Unfortunately you don't get to drive the BA Falcon, you have to drive in a VY commodore (And Skaifey's. Ahh the pain!). Needless to say that on the straight you don't have the power to keep up. (Maybe it was the deliberate crashes I did the the HRT commodore. Hmmm.)
It definately looks like it's gonna be a great game to get, Even better than RD1!
My Major gripe with it though, is the pitstops. It just is a black screen, with a similar setup to the last game. (Here's me hoping for a EA F1 sim style pitstop).
Anyway I recommend that you download it, if only to get used to the physics of the game, in preparation for it's release.
