What Mexican city is used for urban races in Forza Horizon 5?

Guanajuato is the Mexican city used for urban races in Forza Horizon 5. The city appears as part of the game’s fictionalized representation of Mexico and provides a dense setting for street-racing events.

Its narrow roads, steep hills, colorful buildings, plazas, and underground tunnels give the races a very different character from the game’s desert highways, beaches, jungles, and volcano. Guanajuato also features prominently in the Street Scene progression, including the Guanajuato Expedition that introduces the street-racing branch of Horizon Adventure.

The game does not recreate Mexico as a one-to-one map. Instead, Playground Games combines recognizable landmarks, landscapes, and architectural influences into a compressed open world. That is why Guanajuato can sit near other dramatically different regions while still serving as the principal urban-racing environment.
