Highly likely to return based on appearances in Forza Horizon 4 and 5; not yet officially announced for FH6 at the time of writing.
About the 2015 Koenigsegg One:1 in Forza Horizon
Hypercars are the lab experiments of the road-car world. 2015 Koenigsegg One:1 carries that distinction with bespoke aero, bespoke materials, and cost decisions that make sense only when production volume is measured in hundreds, not thousands. In Horizon's X-class, machines like this usually arrive geared for top speed but tunable for technical circuits.
2010s saw turbocharging, hybridization, and active aero arrive at every tier. Koenigsegg adopted these on the One:1 platform with results visible in lap times.
In-Game Classification
2015 Koenigsegg One:1 sits in the Hypercars bracket of the Forza Horizon car list. X-class on this chassis is where the build philosophy diverges — top-speed runs, drag tunes, and aero-loaded circuit specs all stay viable depending on event type.
The RWD drivetrain shapes how One:1 responds to power and tire upgrades — every Forza Horizon entry rewards drivers who understand what their drivetrain layout means for weight transfer in corners.

Where Koenigsegg Sits in Forza Horizon 6
Koenigsegg contributes a substantial slice of the Forza Horizon 6 vehicle catalog. The One:1 fits into that broader Koenigsegg lineage — every entry on the wiki cross-references its in-game class, drivetrain, and country of origin to help players plan their Festival Playlist garage. For a Sweden-built Hypercars machine in the X class, this is one of the more interesting picks in the full 896-vehicle catalog.
