Given how far behind they were in their attempt of the tire development in the first one, and never got that sorted, I doubt it has been by now. And then add different driving disciplines, there's no way. But the tracks are updated material that was held back from pC1 release for future cash-in, with all inaccuracies that rival ISI still in big evidence. The bugs and glitches speak for themselves with lackluster AI. And then there is the game design and single-player options. pC1 advertised an amazing premise and released something that had nothing to do with it.
pC2 is promising a lot but buying this before waiting a few months of reviews, bug reports, and user comments to flesh out, is too naïve.
