Forza Horizon 6 Fastest Cars

The fastest cars in Forza Horizon 6 live in the top two performance brackets: S2 (hypercar tier, optimised for top speed and acceleration) and the new R Class (track-focused, aero-heavy). This page rounds up the candidates from the official Forza Horizon 6 car list, explains why R Class is not always the fastest on top end, and links out to the community-tuned tier lists that update live as the meta shifts.

Direct answer: what is the fastest car in FH6 right now?

If you searched what is the fastest car in Forza Horizon 6, the current community answer is usually the 2021 Hennessey Venom F5. It is the car that keeps showing up at the top of post-launch fastest-car guides and leaderboard discussion because it combines huge top-end speed with the kind of S2 setup that straight-line runs reward.

We still keep the wording careful here: the official Forza source confirms which cars exist in the roster, but it does not publish final tuned top-speed values. That is why this page gives you the live shortlist and class context instead of pretending there is a permanent single answer.

Top-speed shortlist players usually compare next

The highest-intent follow-up search is rarely just fastest car FH6. Players normally pivot into comparisons like Venom F5 vs Jesko or ask for a broader top speed list. These are the four names worth checking first:

Why S2 wins top-speed runs

S2 is the hypercar tier of the Forza Horizon 6 Car List. S2 cars are built around peak power and minimal aero — they reach the highest top speeds in tuned setups. If your goal is a top-speed record on a long highway or airstrip, you start with an S2 hypercar (Koenigsegg, Bugatti, Hennessey, McLaren) and tune for low downforce and locked top gear.

R Class — fastest around a track, not in a straight line

R Class is new in Forza Horizon 6 and sits above S2 in the class ladder. R Class cars have heavy downforce, slick tires, stiff suspension, and very high cornering speed. The trade-off is straight-line top end: aero drag limits how fast they go on a long highway, even though they crush lap times around a circuit.

See the full R Class car list for FH6 R Class entries. Use R Class when you want the fastest lap time, not the fastest top-speed run.

Best FH6 fastest-car shortlist by search intent

  • Pure top speed: start with Hennessey Venom F5, Koenigsegg Jesko, McLaren Speedtail, Ferrari F80, and similar S2 hypercars.
  • Fastest drag car: use the drag cars guide, because launch traction and gearing matter more than peak velocity.
  • Fastest around a circuit: check R Class and time attack cars instead of treating them as highway cars.

Looking for drag cars? Use the dedicated page

Drag racing is a different sport from top-speed runs. Drag cars are built around launch traction, gear ratio tuning, and shift timing rather than peak velocity. We keep a separate Forza Horizon 6 drag cars page with the best 1/8 / 1/4 / 1-mile picks, a drag tuning starter, and the S1 muscle vs S2 hypercar split. If you came here looking for "fastest drag car in Forza Horizon 6", that page is your answer; this one is for top-speed runs.

S2 Class candidates currently on the official source

The list below is pulled straight from the official Forza Horizon 6 car list. As Forza adds more entries and re-balances performance, the pool will grow. Open any car page for class, pack, and source details.

Total S2 cars on the source: 55. See all of them on the S2 Class page.

Frequently asked questions

Which is the fastest car in Forza Horizon 6?

The fastest top-speed cars in FH6 live in S2 rather than in the new aero-heavy R Class. Current community testing and guide coverage most often put the Hennessey Venom F5 at the top of the straight-line conversation, with the Koenigsegg Jesko, McLaren Speedtail, Ferrari F80, and Pagani Huayra BC in the same shortlist. The official source confirms the roster entries, but not the final tuned speed numbers.

Is fastest car the same as fastest drag car in FH6?

No. Top-speed runs care about peak velocity over a long distance, with low aero drag and tall gear ratios. Drag races care about launch traction, gear-ratio stacking to the strip length, and shift timing. A tuned S2 top-speed hypercar will often lose a 1/8 mile drag to a Dodge Demon because it cannot put power down off the line. See the dedicated Forza Horizon 6 drag cars page for the drag picks and tuning starter.

Are R Class cars the fastest in FH6?

Not always. R Class is the new track-focused performance bracket above S2, but R Class cars are built around lap time, not pure top speed. They have heavy aero (downforce) which limits top end. A tuned S2 hypercar with low-drag setup will often beat an R Class car in a straight-line top-speed contest. Use R Class when you care about lap time, S2 when you care about top speed.

Do all fastest-car lists update post-launch?

Yes. Forza adjusts performance index and class assignment after launch, especially in the first few months, so any 'fastest car' tier list will shift. The community megathreads on r/ForzaHorizon and the official Forza forums maintain live tier lists. Our page links to those rather than baking in numbers that go stale.
