This street racing track originally ran around Lago Sur in 2008. That
route was twisty with few straights and those were short. In 2009, they
switched to a completely unrelated route farther north. Not only was
it unrelated, but the new route was given a completely different
character. Forget twists. Instead, it was basically something like
AVUS with kink in the middle: Run down a street, turn around and drive
back where you turn around again.
For both layouts, I included
map overlays, a polygon for the track layout, a path for pit road,
placemarks for each turn, and more. You can get the KMZ
here.
