Thermalito is back! and this time, it’s evolved…
This is a brand-new release rather than an update to the 2023 version, as Thermalito 2025 introduces a major layout change with a new cut corner at Turn 1. The original 2023 circuit remains available as its own separate version, keeping the history and racing lines of that layout alive for anyone who prefers the original route.
Reminder: Thermalito 2025 installs to a different folder than Thermalito 2023, so you can keep both tracks installed at the same time without any conflict. 202 download is still available here.
There are now three layouts.
Thermalito
Short
T1 Cut (the new one)
There are a few fixes to the pit lane, as people were clipping the edges to gain some time. Track surfaces around joins have been tidied up.
To accommodate the new T1 lots of the trackside infrastructure that was the inside of old T1 has been removed.

About the Track
Circuit Thermalito is a 5.035 km fictional temporary race circuit based on a real-world location. The roads surrounding the Thermalito Dam in Oroville, California. The layout weaves between concrete dam walls, along the water’s edge, and through two tunnels inside the dam itself. The Thermalito Circuit features steep elevation changes, sweeping banked corners and tight technical sections.
Originally created by DDF Racer for rFactor over fifteen years ago, Thermalito has since been completely rebuilt from scratch by Nukedrop, using high-resolution photogrammetry, drone imagery, and modern materials to bring the location to life for Assetto Corsa.
