Real-World History
Koenigsegg revealed the Jesko in 2019, named after company founder Christian von Koenigsegg's father. The car uses a twin-turbocharged 5.0-liter V8 engine producing 1,280 horsepower on standard fuel and 1,600 horsepower on E85 racing biofuel. The Jesko Absolut variant targets a 500-kilometers-per-hour top speed; the Attack variant emphasizes downforce and circuit performance instead. Production is limited to 125 cars total across all variants.
Specifications
Jesko Forza Horizon car chassis details: code Jesko; class at stock tune X; category Hypercars; tags include hypercar, top-speed, swedish.
In the Forza Horizon Series
The Jesko debuted in Forza Horizon 5 as a Festival Playlist top-tier reward, and Horizon 6 includes both Absolut and Attack variants in the standard catalog. The car typically anchors X-class events alongside the Bugatti Chiron Pur Sport and Pagani Huayra R.
The Jesko Forza Horizon car appears across 3 entries: FH4, FH5, FH6. As a Jesko Forza Horizon car entry, it sits in the X-class bracket at stock tune.
Tuning Notes
The stock car is already optimized for top-speed runs; for Drag Strip events, fit the longest available final drive ratio and minimal aero. For circuit competition, switch to the Attack variant in tuning if available, otherwise add maximum downforce and stiffen the suspension to maximum. Tire selection matters more than power upgrades at this performance tier — the chassis already exceeds what most tracks can practically accommodate.
For the Jesko Forza Horizon car, the most successful community blueprints share a few common adjustments: balanced aero, tire compound matched to event surface, and gearing tuned for the specific Festival Playlist scenario rather than maximum top speed. The Jesko Forza Horizon car responds best when the tuner respects the chassis's inherent character rather than trying to mask it with extreme settings.
Trivia & Lore
Koenigsegg's nine-speed Light Speed Transmission uses no synchronizers and shifts so quickly that drivers report it feeling continuous rather than stepped. The Jesko's actual top speed has not yet been independently verified, with Koenigsegg suggesting record attempts will happen on a closed runway in 2026.
