Project Endurance drops a supercar car onto a rain-soaked Nürburgring and hands you the keys. Free Drive opens the complete circuit and pit lane, while challenges unlock new cars and finishes for the garage. There is also a timed rescue mission, four-player online rooms, a wonderfully suspicious UFO encounter, and Photo Run, which places photographers around the track before replaying your lap through broadcast cameras.

All of this runs in the browser on desktop and mobile, with Vivaldi, Mozart, and synthwave available on the radio when tire noise becomes too conventional. Anderson Mancini built the game with Three.js on WebGPU, using TSL for the rendering and Rapier for a vehicle simulation with its own tire and drivetrain model. GPU-driven rain, changing daylight, wet asphalt, live reflections, compressed textures, engine audio, and streaming circuit geometry turn the track into something more substantial than a technical demo. Pick a mode, adjust the time of day, and try to keep the expensive machinery facing roughly forward.
