If you’re looking to dominate the highways of Mexico, you need to know what is the fastest car in forza horizon 5. Forza Horizon 5 offers a vast garage, but the car capable of reaching the highest top speed is a technical marvel.
This guide will not only name that car but explain how to get it, tune it, and use it to set blistering speed records. We’ll cover the top contenders, the tuning secrets, and the best places to test your ultimate speed machine.
What Is The Fastest Car In Forza Horizon 5
The undisputed king of top speed in Forza Horizon 5 is the 2011 Koenigsegg Agera RS. In optimal conditions with a perfect tune, this Swedish hypercar can reach a verified top speed of over 310 mph (approximately 499 km/h) on the game’s long highway straight.
It’s important to distinguish between different types of speed. The Agera RS excels in raw, straight-line top speed. Other cars may accelerate faster off the line or handle corners better, but for pure velocity, the Agera RS holds the crown. Its combination of a lightweight carbon fiber body and a monstrous 5.0L V8 twin-turbo engine, outputting well over 1,300 horsepower when fully upgraded, makes it a missile on wheels.
Top Contenders For Ultimate Speed
While the Koenigsegg Agera RS is the fastest, several other vehicles come incredibly close and are worth considering for different reasons, such as availability or handling at extreme speeds.
The 2018 McLaren Senna
Often mistaken for the fastest due to its incredible acceleration and downforce, the Senna is built for track corners, not just top speed. It can still reach impressive speeds over 280 mph with the right configuration, but it’s not the absolute top contender.
The 2020 Koenigsegg Jesko
This is the Agera RS’s closest rival. Designed to break records, the Jesko can hit very similar top end speeds, often within a few miles per hour of the Agera RS. Some tunes and conditions may even see it match the record. Its advanced aerodynamics make it slightly more stable for some drivers at the absolute limit.
The 2019 Bugatti Divo
A masterpiece of engineering, the Divo focuses on high-speed cornering. Its top speed is lower than the Koenigseggs, typically capping around 270-280 mph, but it feels planted and secure, making it a more forgiving option for pushing limits.
How To Acquire The Koenigsegg Agera RS
Getting your hands on the fastest car requires some effort. It is not available for direct purchase from the Autoshow at the start of the game. Here are the primary methods to add it to your collection.
- The Auction House: This is your most reliable bet. Search for “Koenigsegg Agera RS” in the Auction House. Be prepared with a large sum of credits, as it often sells for between 2,000,000 and 3,000,000 CR, sometimes more. Check frequently, as listings can be competitive.
- Wheelspin Prize: The Agera RS is an extremely rare potential reward from Wheelspins. While possible, relying on this method is not practical due to the incredibly low odds.
- Festival Playlist Reward: Occasionally, the Agera RS is offered as a seasonal championship reward. You must complete a specific set of challenges during that season to win it for free. Always check the Festival Playlist each week.
Essential Tuning For Maximum Speed
Owning the car is only half the battle. A stock Agera RS is fast, but a properly tuned one is a world-beater. Here are the critical tuning adjustments to maximize its top speed.
Transmission And Gearing
This is the most important step. You need to extend the gears to allow the engine to reach its maximum potential before hitting the rev limiter.
- Install the “Race Transmission” upgrade.
- Enter the tuning menu and go to the “Transmission” section.
- Adjust the “Final Drive” ratio to a lower number (e.g., around 2.50). This makes all gears longer.
- Fine-tune the individual gear ratios, focusing on the 6th and 7th gears, making them as long as possible while ensuring the car can still accelerate in them.
Aerodynamics And Downforce
For pure top speed, you want minimal drag. Reduce downforce to its lowest settings on both the front and rear wings. This makes the car less stable, especially at lower speeds, but is necessary for breaking the 300+ mph barrier.
Tire Pressure And Alignment
Increase tire pressure slightly (to around 28-30 psi) to reduce rolling resistance. For alignment, a small amount of negative camber (around -1.0 to -1.5 degrees) can help stability, but keep toe settings close to zero to avoid unnecessary drag.
Best Locations To Test Top Speed
You need a long, perfectly straight road to reach the car’s maximum velocity. The game’s map has one premier location for this.
- The Main Highway: The multi-lane highway running down the eastern side of the map is the undisputed best spot. Use the long southern section for the best results. Start your run from the southernmost bridge and head north for the longest possible straight.
- The Airport Runway: The Aeródromo en La Selva runway is a good secondary option. It is perfectly flat and straight, but shorter than the highway, so you may not reach the absolute maximum speed before running out of room.
- Horizon Mexico Circuit: While not a public road, the long main straight on this circuit is a controlled environment useful for comparing acceleration and speed before a corner.
Step By Step Guide To A Record Run
- Acquire and fully upgrade your Koenigsegg Agera RS with all engine and platform/handling upgrades.
- Apply a top speed tuning setup, either by carefully following the tuning principles above or by downloading a proven tune from the community. Search for “Max Speed” or “300+ MPH” tunes.
- Set your game to solo mode to eliminate traffic and other players for a clean run.
- Fast travel to the southern end of the eastern highway.
- Point your car north, ensure you are in manual transmission mode for optimal gear control, and begin your acceleration.
- Shift gears at the optimal point, usually just before the redline, to maintain power band.
- Monitor your speedometer as you build velocity through 250, 280, and 300 mph. Be prepared for subtle steering adjustments as the car becomes very sensitive at these speeds.
Common Mistakes And How To Avoid Them
Even with the right car and tune, small errors can prevent you from hitting the record books.
- Using Automatic Transmission: The game’s automatic shifting is not optimized for extreme top speed runs. It will shift too early. Always use manual shifting for maximum control.
- Incorrect Tire Compound: For top speed, you want the “Drag” tire compound, not “Slick” or “Street.” Drag tires offer the least rolling resistance at very high speeds.
- Too Much Downforce: It’s a common error to add downforce for stability. Remember, downforce creates drag. For a pure top speed run, minimize it.
- Not Enough Runway: Starting your acceleration too late on the highway is a frequent issue. Begin from a complete stop at the very southern point to use every meter of asphalt.
Frequently Asked Questions
What Is The Fastest Car You Can Buy From The Autoshow?
The fastest car available for direct purchase from the Autoshow at any time is the 2018 McLaren Senna or the 2020 Koenigsegg Jesko. However, their top speed is slightly lower than the Agera RS when both are fully tuned. The Jesko is the better autoshow choice for a top speed build.
Is The Hennessey Venom F5 The Fastest?
While the Hennessey Venom F5 is one of the fastest cars in the world in reality, its in-game counterpart in Forza Horizon 5 is not the absolute top speed leader. It is exceptionally fast, with a top speed over 300 mph, but it generally ranks just behind the Koenigsegg Agera RS and Jesko in verified community tests.
What Affects Top Speed The Most In Tuning?
The single biggest factor is your final drive and gear ratios in the transmission. Making the gears longer allows the engine to build more speed in each gear before needing to shift. After that, reducing aerodynamic downforce is the second most critical adjustment to lower drag.
Can Any Car Become The Fastest With Tuning?
No. While tuning can dramatically improve a car’s top speed, it is limited by the car’s base stats, engine potential, and aerodynamic profile. A Volkswagen Beetle, no matter how well tuned, cannot reach 300 mph due to game physics and upgrade limitations. Hypercars with high base power and good aerodynamics benefit the most.
Where Can I Find The Best Top Speed Tunes?
The best place is in the in-game Tune Browser. Go to your garage, select “Tuning,” then “Find Tunes.” Search for your car (e.g., Koenigsegg Agera RS) and then look for tunes with titles like “MAX SPEED,” “V1 Top Speed,” or “500 KM/H.” Check the creator’s share code and their rating for reliability. Popular tuners often have proven setups.
