I was in Birmingham over the weekend and noticed a Honda stand with a few Xbox's and Type R's outside. When I got closer I also heard the sounds from what sounded like Assetto Corsa. When I investigated further what was going on was you had to do a quick-ish lap on Forza 5 at Nurburgring GP, then you had to do the same thing on their full simulator with motion rig. The full sim was running AC.
I didn't do very well, the top guys were doing 2:10.5's, obviously word had gotten round that this was going on and there were some really quick guys taking part, some guys had queued up 8 times according to one bloke I spoke to, it took me 40 minutes just to queue up once! Anyway, you get 2 laps and then that's it. The fastest lap apparently gets the Type R for 12 months.
My first lap was a 2:21, then my second lap was a 2:16. I didn't bother queuing up again as I didn't have time and I don't think id improve by 6 seconds anyway.
I'm not sure what all the references are to the full 'Ring, the track on both occasions was Nurburgring GP. Perhaps a later stage is at the full Nordschliefe...?
