This track was also made by Martin Ata and Lanusteamracing in 2011, which you can find at rFactor Central. The 2011 version had an older lay-out, but was for 2011 rFactor standards a modest decent looking track, with only one big omission; there was no real raceline. The cars drove exactly on the middle of the track.
The version made by Gonzaluigi has two new lay-outs, and looks like a "quick and dirty" track, even by 2011 rFactor standards. There is no grass surrounding the track, what you see looks like a enhanced satellite image. And, as a big surprise, again there is no real raceline, the cars drive exactly on the middle of the track !!!
