Quick Take
The fastest stock-tuned cars in FH5 sit around the 300 mph mark, led by the Hot Wheels DLC’s Hennessey Venom F5 and the Koenigsegg Jesko. This page ranks the fastest cars by documented top speed. The FH6 top-speed leaderboard is unconfirmed as of May 2026.

Top 10 Fastest Cars in Forza Horizon 5
Numbers refer to in-game performance on long straights with top-speed tuning applied, not stock acceleration figures.
| Rank | Car | Top Speed (mph) | Top Speed (km/h) | Notes |
|---|---|---|---|---|
| 1 | Hennessey Venom F5 | ~307 | ~494 | Hot Wheels DLC required |
| 2 | Koenigsegg Jesko | ~305 | ~490 | Fastest non-DLC car |
| 3 | Mosler MT900S | ~296 | ~476 | Lightweight value pick |
| 4 | Rimac Nevera | ~294 | ~473 | Fastest EV |
| 5 | Koenigsegg Agera RS | ~280 | ~451 | |
| 6 | Koenigsegg One:1 | ~277 | ~446 | |
| 7 | Bugatti Chiron | ~274 | ~442 | |
| 8 | Bugatti Veyron Super Sport | ~270 | ~435 | |
| 9 | Hennessey Venom GT | ~269 | ~434 | |
| 10 | McLaren Speedtail | ~265 | ~427 |
The Venom F5 narrowly edges the Jesko, but the Jesko is the more popular choice because it’s accessible without DLC. The Mosler MT900S is the standout value pick — at 1,225 kg it’s vastly lighter than the hypercars above it.
Koenigsegg Jesko: The Community Benchmark
The Jesko is the car most FH5 players think of when someone says “fastest car.” It clears 300 mph with a top-speed tune and is the fastest non-DLC car in the game.
- Top speed: ~305 mph / 490 km/h
- Class: S2 / Hypercar
- Why people pick it: No DLC required, balanced handling for a top-speed build, abundant community tunes
- Best use: Long highway runs, Goliath, drag/speed traps
Community tunes can push the Jesko to 320+ mph in unrestricted runs, but those builds sacrifice every other performance dimension.
Mosler MT900S: The Lightweight Sleeper
The Mosler reaches roughly 296 mph / 476 km/h with the right tune while remaining significantly cheaper and lighter than the top hypercars.
- Weight advantage: ~1,225 kg vs. ~1,420 kg for the Jesko
- Engine swap potential: Accepts heavy turbocharged swaps without ruining handling
- Price: Far cheaper than top-tier hypercars, accessible early in a save
It’s the most-recommended car for players who want top-speed glory without grinding for the most expensive hypercars.
Bugatti Chiron, Veyron Super Sport and Other Notables
The Chiron reaches roughly 274 mph in-game; the Veyron Super Sport tops out near 270 mph. Neither competes with the Jesko or Venom F5, but both deliver more stable handling at speed.
Other notable entries:
- Hennessey Venom GT (~269 mph): Older Hennessey, still relevant
- McLaren Speedtail (~265 mph): Aerodynamic, well-balanced
- Koenigsegg One:1 (~277 mph): Cheaper alternative to the Jesko
- Hoonicorn Ford Mustang (~250 mph): AWD launch monster, but capped lower
For speed-trap challenges, the Jesko, Venom F5, and Mosler consistently win. For balanced PR-stunt builds, the Chiron and Speedtail are easier to drive at the limit.
What About Forza Horizon 6?
The official FH6 top-speed leaderboard has not been published as of May 2026. Pre-release coverage suggests the Koenigsegg Jesko, Bugatti Chiron, and Rimac Nevera all return.
What’s worth tracking once FH6 is live:
- Whether the Hennessey Venom F5 returns base-game or is again DLC-locked
- New entries (e.g., Koenigsegg Jesko Absolut, newer Rimac/Bugatti models)
- Tune ceiling changes — FH6’s revised physics may shift the relative ranking
The FH5 list above is the reliable reference until in-game numbers are verified.
FAQ
What is the fastest car in Forza Horizon 5?
The Hennessey Venom F5 (Hot Wheels DLC) at around 307 mph / 494 km/h. Without DLC, the Koenigsegg Jesko is fastest at around 305 mph / 490 km/h.
Is the Mosler MT900S really one of the fastest cars in FH5?
Yes. The Mosler reaches roughly 296 mph / 476 km/h with a top-speed tune, and its low weight makes it cheaper and easier to build than the top hypercars.
Is the Koenigsegg Jesko the fastest car without DLC?
Yes. The Jesko clears 300 mph with a proper top-speed tune and no DLC required.
What is the fastest electric car in Forza Horizon 5?
The Rimac Nevera, with a top speed of around 294 mph / 473 km/h in-game.
How fast is the Bugatti Chiron in Forza Horizon 5?
Around 274 mph / 442 km/h with a top-speed tune. The Veyron Super Sport sits slightly behind at ~270 mph.
Will the same fastest-cars list apply to Forza Horizon 6?
Likely similar but unconfirmed as of May 2026. Playground Games has not published an official FH6 top-speed ranking, so the FH5 list is the current reference.
