What are the top 10 fastest cars in Forza?

[KaydenFitz]

The Koenigsegg Jesko is the fastest car in Forza Horizon 5, capable of reaching a verified top speed of over 305 mph (490 km/h) with the correct tuning. Top speed, however, depends heavily on player tuning skill and specific in-game conditions. The following ranking is based on community testing and widely accepted performance data for stock or optimally tuned vehicles within the game's current version.

Ranking	Car Model	Verified Top Speed (MPH)	Key Characteristic
1	Koenigsegg Jesko	305+	Highest top speed potential; requires expert tuning.
2	Rimac Nevera	295-300	Instant electric torque; dominant acceleration.
3	Koenigsegg Agera RS	285-290	Excellent high-speed stability from a legendary hypercar.
4	Koenigsegg One:1	278-282	Named for its perfect 1:1 power-to-weight ratio.
5	Bugatti Chiron	273-277	Iconic design with immense power and refined handling.
6	McLaren Speedtail	267-272	Streamlined design focused on breaking speed records.
7	Hennessey Venom F5	265-270	Newer American hypercar with extreme power output.
8	Ferrari 599XX Evolution	260-265	A track-focused monster that excels on highways.
9	Koenigsegg Gemera	258-263	A practical hybrid hypercar with surprising top-end.
10	Jaguar XJ220S TWR	255-260	A classic 90s supercar that remains competitive.

Achieving these maximum speeds is not automatic. Players must engage in performance tuning, specifically adjusting the final drive ratio in the gearbox for longer gears, and ensuring the car has maximum horsepower upgrades installed. Aerodynamics also play a critical role; lowering downforce can increase top speed but makes the car less stable.

Community data from time trials and dedicated speed traps on the game's long highway confirms these figures. It's important to note that some historically fast cars, like the Porsche Taycan Turbo S, have realistic top speeds closer to 200 mph, not 270 mph as sometimes mistakenly listed. The ranking prioritizes realistic, achievable speeds within the game's physics as proven by the player base, not just manufacturer claims or base statistics.

The "fastest" car can also depend on the metric. For pure acceleration 0-60 mph or quarter-mile times, the Rimac Nevera is untouchable due to its electric powertrain. For consistent speed across varied road conditions, the Bugatti Chiron or Koenigsegg Agera RS might be more forgiving than the peakier Jesko. Ultimately, the top speed chase is a dedicated endgame activity for seasoned players.

As someone who spends hours tuning in the garage, I can tell you the listed top speeds are just a starting point. My tuned Jesko hit 307 mph, but that required fine-tuning the gear ratios for the highway and minimizing downforce. The car was a handful to drive. For a more balanced experience, I’d recommend the Bugatti Chiron. It’s incredibly stable at 270+ mph, which makes it far more usable for most players. The Rimac Nevera feels like cheating off the line—it’s that quick.

I’m a casual player who loves collecting cars, not a hardcore tuner. So when I wanted to break 300 mph, I went online and downloaded a tuning setup from a top-rated creator. I slapped it on my Jesko, drove to the highway, and finally saw that magical number. It was a thrill. My advice? Don’t get bogged down in the tuning details if it’s not your thing. The community has already done the work. Search for “top speed tune” for any car on this list, and you’ll be set for your own speed run.

Forget just top speed for a second. The real question is: where are you driving? The Ferrari 599XX Evo is my favorite for the Horizon Mexico circuit because its downforce helps it corner. But on the flat, straight highway, it can’t beat the Jesko. The Rimac Nevera wins every drag race but runs out of breath near 300 mph. Different cars are “fastest” for different events. This top ten list is your toolbox. Pick the right tool for the job, whether it’s a drag strip, a road race, or just chasing a speed trap record.

Let’s talk about what “fastest” really means in Forza. There’s a difference between a car’s potential and what you can actually achieve. The game’s physics model means horsepower, weight, aerodynamics, and gear ratios all interact. A car with less power but better aerodynamics might beat a more powerful car. I’ve tested the Jaguar XJ220S against modern hypercars, and it holds up because of its shape. Always install all horsepower upgrades and use race tires. Then, in the tuning menu, set the final drive to a higher number for longer gears. This simple adjustment often adds 10-20 mph to your top speed, moving a car up the rankings.
