The Hennessey Venom F5 is the leading reported top-speed car in Forza Horizon 5, with the Koenigsegg Jesko close behind. In Horizon Hub’s ranking, updated May 14, 2026, their approximate tuned long-straight speeds are 307 mph and 305 mph, respectively. Treat those as guide estimates, not official leaderboard results: tune, conditions and game updates can change the outcome.
Fastest cars in Forza Horizon 5: ranked
Horizon Hub’s May 14, 2026 guide ranks these cars by approximate in-game performance on long straights with top-speed tuning applied. The figures are not stock acceleration statistics, and they do not establish which car is quickest around a circuit.
| Rank | Car | Approx. tuned top speed | Access or useful context |
|---|---|---|---|
| 1 | Hennessey Venom F5 | 307 mph / 494 km/h | Listed by Forza’s official roster as Autoshow DLC from the Hot Wheels Expansion. |
| 2 | Koenigsegg Jesko | 305 mph / 490 km/h | Listed in the official roster; an alternative to the F5 if you do not have the Hot Wheels Expansion. |
| 3 | Mosler MT900S | 296 mph / 476 km/h | Described as a lower-cost option by Horizon Hub; no specific price is stated. |
| 4 | Rimac Nevera | 294 mph / 473 km/h | Horizon Hub’s fastest electric entry in this ranking. |

Why the Venom F5 and Jesko are close contenders
The F5 leads this particular tuned-speed list, but the roughly 2 mph gap over the Jesko should not be read as a universal or precisely reproducible margin. MotorTrend also identifies the Venom F5 as the game’s fastest top-speed car and says it can exceed 300 mph. A 2026 StopShop guide places the F5 around 305–307 mph and the Jesko around 305 mph. These are independent guide estimates, not results from a standardized official test.

Build and conditions matter. GamesRadar+ reports an author-observed Jesko highway speed of around 283 mph, illustrating why a highway run, stock behavior and a purpose-built top-speed tune can produce different numbers. The ranking above is specifically for tuned long-straight performance.

For a fast option without the Hot Wheels Expansion
Consider the Koenigsegg Jesko. It is listed in the official car roster and sits just behind the F5 in the cited top-speed ranking.
For value or an electric entry
Horizon Hub characterizes the Mosler MT900S as a lower-cost option and the Rimac Nevera as the fastest electric car on its list. Those are the guide’s descriptions, not independent price comparisons or controlled tests.

For races beyond a long straight
Maximum speed alone does not tell you which car is best for a drag run, speed trap, circuit or all-round driving. A car that reaches a higher peak may not be the most useful choice when acceleration, braking, cornering and control matter. GamesRadar+ likewise distinguishes “fastest” from “best” and recommends experimenting with custom and community tunes.

How to use this ranking
- Use the listed figures as approximate tuned top-speed targets, not promises for a stock car or every tune.
- For a fair comparison, use the same long straight and comparable tuning conditions; record the result in your own build rather than assuming the guide’s maximum will transfer exactly.
- Choose a car for the event objective. Peak speed is relevant to long straights and some speed challenges, but is not a complete measure of race pace.
