When it comes to top speed in Forza Horizon 6, some cars just leave the competition in the dust. This isn't about drift skills or handling on tight turns—this list is purely about which cars can hit the highest speeds.
Here's the rundown from 5 to 1.
5. Lotus Avaia Forzer Edition – 294 mph
- Type: Forzer Edition
- Top Speed: 294 mph
- Notes: Usually tuned for drifting, but with the right top-speed setup, this car can rival any speed demon in the open world. It shares the fifth spot with another Forzer Edition car.
5. Porsche 917 Forzer Edition – 294 mph
- Type: Forzer Edition
- Top Speed: 294 mph
- Notes: A classic hypercar with a Forzer Edition tune, technically tied with the Lotus Avaia. Achieving this speed requires a clean run with minimal obstacles.
4. Mental Mazda MX5 Forzer Edition – ~296 mph
- Type: Forzer Edition (Drag Setup)
- Top Speed: Approximately 296 mph
- Notes: This car is optimized for drag racing. Hitting its maximum requires a perfect approach—traffic and small bumps can easily reduce speed.
3. Hennessy Venom F5 – ~306 mph
- Type: Hypercar
- Top Speed: Around 306 mph
- Notes: Surprisingly, the Venom F5 doesn't claim the top spot despite its legendary performance. Traffic can impact runs, so multiple attempts might be needed to hit its top potential.
2. Nissan GTR R35 Forzer Edition – ~306 mph
- Type: Forzer Edition (Drag Setup)
- Top Speed: Around 306 mph
- Notes: A drag beast that also happens to be one of the fastest in the game overall. Like the Venom, it sacrifices turning ability for raw speed.
1. 1985 Toyota Sprinter Trueno GT Apex / AE86 Forzer Edition – 321–322 mph
- Type: Forzer Edition (Custom Engine Swap)
- Top Speed: 321–322 mph
- How to Unlock:
- Complete the Discover Japan section in the Collection Journal.
- Achieve Master Explorer status with 5,000 points.
- Tuning Tips for Max Speed:
- Engine: Swap in a 2JZ, convert to AWD, and add a single turbo.
- Body: Remove stock body kit, install Toyota kit, remove spoiler.
- Suspension: Rally springs and dampers; make car as light as possible (~856 kg).
- Transmission: Keep standard; use race differential.
- Tires & Wheels: Slick tires, lightest rims (~18 kg).
- Track Width: Increase front and rear.
- Notes: With perfect tuning, the AE86 can hit 322 mph. This is insane for a car traditionally known for tight cornering, and it dominates the top speed leaderboard.

Top speed in FH6 isn't just about horsepower; setup and tuning play a massive role. While classic hypercars like the Venom F5 and Nissan GTR are fast out of the box, the custom AE86 Forzer Edition steals the crown for sheer velocity. For open-world speed runs or drag challenges, these five cars are your go-to choices.
