I am yet to come across something from their group that is more than a good looking model with sharp textures. Nothing else unfortunately. I wish this guy hadn't disappeared: http://www.virtualr.net/prototype-legends-for-rfactor-2-first-previews http://www.virtualr.net/prototype-legends-for-rfactor-2-new-previews
well, normally I would agree, however they (Nissan) said they would share a lot of data, unlike the other teams, and won't hide... they are even going to share their setup data!!! And also, as a small argument, Marussia let ISI use their then current data as well, so while it is not very common, it ins't able to rule it out completely
The reason you hide things in motorsport is to try and stop the competition from copying your good ideas. This doesn't really apply with the Nissan as it uses so many unconventional ideas that most of it is of no use to more traditional lmp1. Also they wouldn't have shown any of the underbody shots, let people near it etc I'd they weren't going to be open about what's going on in the car e.g. we still haven't seen Toyota and audi's cars.
'One of Nissan's PR representatives added to the discourse by laying out their plans for sharing the program with the world. "We don't want to be like the other manufacturers who are guarded, who keep everything under wraps and only tell you what they want to know," he said. "We are going to be wide open. Come on in, see it all, tell your story however you want—guts and all, and we plan to do the same. Post our setup sheets online. Look at all the little technical details, the spring rates, or whatever. Make this your own car, learn from it, ask questions. "We're all adults here, and that's how we're going to treat everyone. There's nothing that's off-limits, and that might take some getting used to for some guys, but that's how we're going about things."'
