TOP 5 fastest cars in Forza Horizon 4 (2026 data)

List of speed leaders in Forza Horizon 4 is formed not only on the basis of maximum speed in a straight line, but also taking into account acceleration, handling and stability at high speeds. We analyzed community data, tests by professional racers and official races to create the latest rankings. It is important to understand that after balance updates, some cars may lose or gain positions, but these models have been at the top for several years now.

All cars in the list below are considered taking into account maximum tuning (including engine, transmission, suspension and aerodynamics) and use gear ratios, optimized for straight high-speed races. Without further ado, meet the champions:

  • πŸ₯‡ Mosler MT900S β€” the absolute king of speed with an indicator of over 480 km/h on straight sections. Its aerodynamics and weight make it virtually invulnerable in drag racing.
  • πŸ₯ˆ Koenigsegg Agera RS - a Swedish hypercar capable of accelerating to 470+ km/h. It is stable at high speeds, but requires precise suspension tuning.
  • πŸ₯‰ Hennessey Venom GT - American power with indicators close to Agera RS, but more capricious in management. Excellent performance on long straights.
  • 4️⃣ Bugatti Chiron - a legend among hypercars, which in FH4 shows 465 km/h. Ideal for beginners due to its predictable handling.
  • 5️⃣ Jaguar XJ220S TWR - an unexpected dark horse that can compete with modern hypercars thanks to its lightness and power.

Interesting fact: Mosler MT900S is not the most expensive car in the game, but it is the one that has been leading in high-speed races for several years. This goes to show that sometimes engineering is more important than branding. If you want to compete for first place in Speed Trap or Drag Race, start digging towards this monster.

Why is the Mosler MT900S the fastest car in the game?

Mosler MT900S - this is not just a car, but a real high-speed projectile, created in order to break records. Its superiority over other hypercars stems from several key factors that make it the ideal choice for those seeking top performance.

Firstly, this power to weight ratio. Even in stock version MT900S weighs only about 1 ton, and after tuning this figure can be reduced even more, while simultaneously increasing power to 1500+ hp. Secondly, his aerodynamics designed to minimize air resistance at high speeds, which is critical for drag racing. And finally, gearbox in this car allows for optimal distribution of power, avoiding losses during acceleration.

But there is also the other side of the coin: Mosler extremely unstable when cornering and requires perfectly smooth roads. On roads with winding sections, it loses to more balanced cars like Koenigsegg Jesko or McLaren Speedtail. Therefore, it should be chosen only for races where the priority is maximum straight line speed.

⚠️ Attention: When tuning Mosler MT900S never set the maximum ground clearance - this will worsen the aerodynamics and reduce the maximum speed by 10-15 km/h. Optimal value: Minimum ground clearance + Stiff suspension.

How to tune a car for maximum speed?

Even the fastest car in Forza Horizon 4 will not show its potential without proper tuning. Many players mistakenly think that it is enough to max out the engine and tires - but this is only part of the story. To get the most out of a car, you need to work with each parameter, from gear ratios to aerodynamics.

Here are step-by-step instructions on how to set up a car for high-speed races (using the example Mosler MT900S, but the principles apply to other models):

Set engine level to maximum (Extreme tuning)

Select gearbox Racing with manual switching

Adjust gear ratios for maximum speed (reduce final drive)

Set minimum ground clearance and stiffer suspension

Use tires Slicks for better grip at high speeds

Add maximum rear spoiler for stability

Remove all unnecessary parts (bumpers, hood) to reduce weight -->

Pay special attention gear ratios. In the tuning menu, go to the section Transmission β†’ Final drive and reduce the value until the car begins to reach maximum speed in last gear. For MT900S the optimal value is about 2.80-3.00. If you leave the standard settings, the car simply will not be able to accelerate to its limit.

Another secret: after tuning, be sure to test the car for Test track (available in menu Free ride). Record the acceleration time to 400 km/h - if it exceeds 30 seconds, it means that the gear ratios are not configured optimally. Also make sure that the car does not bounce at high speeds - this is a sign of too stiff a suspension or incorrect ground clearance.

πŸ’‘

If your car "yaws" at speeds above 400 km/h, try increasing the rear spoiler by 1-2 levels. This will add downforce, but will slightly reduce the top speed (by 2-5 km/h).

The best tracks for speed records

B Forza Horizon 4 Not all tracks are equally good for setting speed records. For example, mountain serpentines or city streets with turns are not suitable for hypercars - what is important here is not maximum speed, but handling. But there are several locations where you can accelerate to the limit and compete for first place in the leaderboards.

Here are the top 3 tracks for speed racing:

  • 🏁 Drag strip at the airport (Edinburgh Airport) - an ideal place for overclocking tests. A straight line more than 2 km long allows you to accelerate to 450+ km/h. Records are often set here in the mode Drag Race.
  • πŸ›£οΈ M40 (between Ambleside and Keswick) β€” a long, flat road with minimal traffic. Suitable for racing at maximum speed in Speed Trap.
  • πŸŒ‰ Broadway Bridge - a short but very fast section where you can test acceleration. Popular among players who compete in 1/4 mile races.

For example, on Edinburgh Airport Class races are often held S2 (998), so before checking in, check the car requirements in the menu Horizon Festival β†’ Seasonal events.

⚠️ Attention: On the track M40 Sometimes NPC cars appear that can interfere with overclocking. To avoid collisions, use the function Rewind or start the race in mode Solo.
How to bypass the class restriction?

If an event requires a car of class S1, and you only have S2, you can temporarily lower its characteristics. To do this, in tuning, reduce the engine power to the S1 class limit (usually 800-850 hp) and remove some improvements. After the race, return the settings back.

Secrets of control at ultra-high speeds

Driving a car at 450+ km/h is like trying to hold an angry bull on a string. The slightest mistake and you will be turned around or thrown off the track. To avoid this, you not only need to set up your car correctly, but also master a few key driving techniques.

Firstly, never use the handbrake at high speeds. Even a slight touch can lead to a skid, especially on rear-wheel drive vehicles like Hennessey Venom GT. Instead, learn to use engine braking by downshifting before corners. Secondly, avoid sudden steering movements β€” at speeds above 400 km/h, even a small turn can be fatal. Smoothness is your best friend.

Another important point - use of Nitrous (nitrous oxide). B Forza Horizon 4 nitrous gives a short-term but powerful increase in speed. Optimal tactic: activate it on penultimate transmissionwhen the tachometer needle approaches the red zone. This will allow you to quickly get into the last gear and reach maximum speed. Don't waste nitrous at the beginning of the race - it's more effective at high speeds.

And finally, don't forget about aerodynamic braking. On cars with large spoilers (for example, Koenigsegg Agera RS) you can raise the nose slightly before turning to increase downforce on the rear axle. This will help avoid demolition, but takes practice.

πŸ’‘

At speeds above 420 km/h, even a slight wind or uneven road can throw the car off course. Always keep your finger on the button Rewind - in FH4 this is your insurance against failure.

Common mistakes when racing at top speed

Even experienced players sometimes make mistakes that cost them victory in speed races. We have collected the most common mistakes and will tell you how to avoid them. If you've ever lost a race despite having the fastest car, one of these oversights is likely to blame.

Mistake #1: Ignoring weather conditions. B Forza Horizon 4 rain and snow significantly reduce grip, especially on cars with wide slicks. If you see the weather changing, set up your car in advance for a wet track: reduce the tire pressure and add a little downforce at the front. Also avoid driving at maximum speed in Winter season β€” snow and ice will make your car uncontrollable.

Mistake #2: Wrong choice of car class. Many players think that the higher the class (for example, X-Class), the faster the car. But in fact, class cars often win in speed disciplines S2, because they are lighter and accelerate better. Always check event requirements before entering.

Mistake #3: Excessive use of tuning kits. Some improvements, e.g. Offroad tires or Reinforced bumper, add weight and worsen aerodynamics. If you're tuning your car for speed, remove everything that's unnecessaryβ€”every kilogram counts.

  • 🚫 Don't set the suspension for comfort - this impairs handling at high speeds.
  • 🚫 Do not use an automatic transmission β€” it always loses to a manual one in speed races.
  • 🚫 Don't forget to balance your brakes β€” incorrect settings will lead to skidding when braking.

FAQ: Answers to frequently asked questions about fast cars in FH4

What is the fastest car in Forza Horizon 4 without tuning?

Without tuning, the leader in maximum speed is Bugatti Chiron β€” in the stock version it accelerates to 420 km/h. However, after leveling up he is overtaken Mosler MT900S and Koenigsegg Agera RS.

Is it possible to reach 500 km/h in FH4?

Theoretically, yes, but for this you need to use bugs or modifications of the game. Under standard conditions, the maximum speed is limited by the game physics and is about 480-490 km/h in the fastest cars.

Which car is better for drag racing: Mosler MT900S or Hennessey Venom GT?

Mosler MT900S wins in pure acceleration due to lower weight, but Hennessey Venom GT more stable at the start. If the course is short (1/4 mile), choose Venom GT. For long straight lines - Mosler.

How to win at Speed Trap if your opponents have the same cars?

In mode Speed Trap The winner is the one who better tuned the gear ratios and aerodynamics. Try reducing the final gear by 0.1-0.2 compared to the standard settings - this can give an advantage of 5-10 km/h.

Is it worth spending money on a Koenigsegg Jesko if you have an Agera RS?

Jesko faster in corners thanks to active aerodynamics, but loses in pure acceleration Agera RS. If you need a car for high-speed races, it is better to save money and take Agera.
