Located near Shelby, Iowa off of I-80. I was aiming for grade 2, but I don't know if the freestanding marshal post would affect that.

Intended to bring Rio de Janeiro back to the Stock Car Brasil calendar, this 8.48 km street circuit only hosted one race in 2027 before it was cancelled because, frankly, it was incredibly stupid.

The lap opened on the highway Av. Dom João VI with a radically tight right-hand hairpin, before winding down the 7.5 m wide highway onramp to the streets below. After a pair of sketchy hairpins, the track wound up the mountain on the Av. Artur Xexeo, the circuit's namesake. The journey over the mountain was reminiscent of Australia's Bathurst, albeit with less runoff.

After making their way down the other face of the ridge, drivers were met with the harrowing Bob's Burger corner, so named for the restaurant on the inside. This corner was poorly paved and had an exit only 6 m wide. They then headed up the offramp, around another radically tight right-hand hairpin, and back onto Av. Dom João VI. This time they raced through the tunnel under the ridge, before emerging back into the blinding sun just in time for the braking zone for a final chicane with a negligent amount of runoff.

Teams also had trouble using the pitlane, which was just the eastbound lane of Av. Dom João VI. The organizers of the race also forgot completely about spectator seating and viewing, although most fans were satisfied sitting on the grass around the opening complex.
