How many vehicles were available at Forza Horizon 3’s launch? 350.
Forza Horizon 3 launched with 350 available vehicles. That roster was one of the game’s major selling points, covering road cars, classics, off-road vehicles, racing machines, buggies, and trophy trucks.
The game was developed by Playground Games and released in 2016 for Xbox One and Windows. Its fictionalized Australian setting gave the expanded roster a broad playground, ranging from coastal roads and rainforest to desert and outback terrain. Players directed the Horizon Festival and unlocked additional activities by attracting fans.
The number refers to the launch lineup, not the final total after downloadable content and later additions. That distinction explains why larger figures may appear in discussions of the game years after release. Another nearby fact is that Forza Horizon 3 introduced Horizon Blueprint, letting players customize event routes, vehicle eligibility, and other race settings.
