Which Forza Horizon 4 expansion is based on a toyline? Lego Speed Champions.

Lego Speed Champions was Forza Horizon 4’s second major expansion, following Fortune Island. It transforms part of the game world into a Lego-themed setting, with brick-built scenery, collectible Lego objects, and vehicles inspired by the Lego Speed Champions product line.

The expansion reflects a partnership between Playground Games and The Lego Group. It was announced at E3 2019 and released on 13 June 2019. Its campaign uses Lego versions of real cars, while the separate map and Radio Awesome station reinforce the playful crossover.

A common mix-up is confusing this expansion with Hot Wheels. Forza Horizon 3 had a Hot Wheels expansion, while Forza Horizon 4 received Lego Speed Champions. Fortune Island was also an expansion, but it focused on treasure hunting, extreme weather, and a mountainous island rather than a toyline.
