I posted this in another thread but I want to post it here as well and see if others agree.
I believe this to be the first 360 shot we've seen.
I only believe this to be from the 360 version because the lighting and shadowing is far closer to that of the first Horizon (they're working with the same engine from the first Horizon for the 360 version, so I would expect similar lighting), there is significantly more aliasing, the track seems to be surrounded by more fences than anything we've seen yet , and there isn't any grass detail like we've seen in the Xbone media so far.
This all implies that the 360 version is going to be a very different game, and far closer to what we saw from the first Forza Horizon.
This shot is from here:
