Since we've built every track from the ground up (no assets or models were recycled from Forza 1), we've naturally gone in and added a ton of new detail to all the environments. More importantly, the track artists have followed up on a lot of suggestions, as well as corrections from track experts (e.g., track stewards) to make each track more accurate and true-to-life. Hundreds of Gigs of new GPS data (for elevation, dimensions, etc.) and reference materials were collected this time around in the pursuit of realism. Drift fans will be happy to know, for instance, that the drift loop has been added to Road Atlanta -- if nothing else, we do it for the sake of being completist.
