No overheating to speak of, didn't get it above 85 around the ring. The mountain passes fully loaded got the temp up into the mid 90s though lol, still not dangerously high by any means. But that's in an HDi, which are completely over-cooled as standard imo. The XUDs stick a lot more heat into the coolant, but as long as you drive sympathetically and don't just mat it for the full length of every straight it should be fine. A decent fmic should help avoid heatsoak too.
