Could be fictional, could also be a unlicensed real track a la Brianza. "Speedway" makes me believe it's a oval but "Mountain Peak" makes me believe it could be a hillclimb!! Maybe a ISI tester can fill us in.
Wasn't there an old ISI PR screenshot of some sort of mountain/hillclimb-ish track? EDIT: These are the pics I meant:
Found this quote from Scott from 2012 (i lost the link .. but you can search for it) Some tracks we have waiting in the wings to be released over the course of the beta: Mountain Peak Speedway (Oval, infield road course, and 2 kart tracks) Palm Beach International (Road Course and Kart track)--the first of our licensed tracks Quebec SuperKarting (3 layouts)
It definatly is an oval it might sound strange, but try filling 'mountain peak' in the search option -Post from good old Scott Juliano about it (January 2012) -Old post from guy above, suggesting the same ..... and on page 1 of the topic maybe an extra hint (look for: charolette, I know, not spelled right ) (February 2013) -again old post by Scott Juliano, including some other lost info (Toban anyone??? ) (December 2011) EDIT :: Lol, and my searching was beaten, but only just (like 15 minutes, think I searched to much ) EDIT 2 :: I DO have links though lol
The track team has been very quiet recently, someone should give them a poke on Twitter and ask them what's up
