I will be releasing many variants of that track and many others located in the Grand Senora Desert.
Here are my thoughts on a few, and to help with the Hillside Loop variants, take a look at the map at the link above.
Hillside Loop - East Loop: Will feature the eastern section of the track. The starting line will be in the same place, but the track will corner at that easternmost road traveling south again.
Hillside Loop - Mid Loop: This variant of Hillside Loop features the middle section of the track, featuring those two, offroad winding roads, some paved areas will be included.
You Tool Course: The You Tool Course takes place at the You Tool store in Grand Senora Desert. Sanchez's are limited in this race, due to small ramps, tight cornering and uneven terrain that might make it unsuitable for a supercar or onroad car. The course will loop the You Tool Store, also while exploring some of the trails and outback of eastern Grand Senora Desert.
