Ask ten players what should be sitting at the top of Forza Horizon 6's speed charts and most of them will name a hypercar. Fair enough. But once people started testing wild builds across the map, the list got weird fast. Some of the quickest FH6 Cars aren't the ones you'd expect at all, and that's part of the fun. This ranking is about straight-line top speed only, not lap times, cornering, braking, or how useful the car feels in a proper race.
The current speed leader
Rank 1 belongs to the 1985 Toyota Sprinter Trueno GT Apex Sports Tradition, better known to most players as the AE86 Sports Tradition. With the right build, it has been pushed to around 324.1 mph, which is frankly ridiculous for a car most people associate with light handling and old-school drifting. The trick is not magic, though it can feel like it. Players are using a 2JZ swap, all-wheel drive, a single race turbo with anti-lag, slick tyres, maximum weight reduction, light rims, rally springs, a race differential, and a cleaner aero setup with the spoiler removed. Once stripped down to roughly 856 kg, it turns into a tiny missile.
The 300 mph club
Rank 2 goes to the Nissan GT-R R35 Forza Edition, which can sit around 306 mph when tuned for long straights. It's not just fast at the end of the run either. The all-wheel-drive grip helps it get moving hard, so it feels useful for drag racing as well as speed trap attempts. Rank 3 is the Hennessey Venom F5 at about 305 to 306 mph. That one makes more obvious sense. It was built to be a speed-record machine in real life, and in FH6 it still feels clean, stable, and fairly easy to tune compared with some of the stranger builds above it.
Small cars causing big trouble
Rank 4 is the Mental Mazda MX-5 Forza Edition, landing near 295 to 296 mph in strong conditions. It sounds like a joke until you drive it properly. The car is light, it launches well, and its power-to-weight ratio lets it keep pulling far longer than you'd think. Rank 5 is shared by the Lotus Evija Forza Edition and the Porsche 917 Forza Edition, both sitting around 294 mph. The Evija leans on instant electric shove and good high-speed control, while the Porsche feels more like a classic race car that's been dragged into modern Horizon madness.
What players should keep in mind
The Koenigsegg Agera RS still deserves a nod, even if it has slipped out of the top group for now. In the previous game, it was the car everyone talked about for huge speed runs, and it could pass 312 mph in the right setup. FH6 has changed the picture with new upgrade paths, oddball Forza Edition builds, and tuning discoveries that keep moving the goalposts. If you're building your garage around speed, the wider Forza Horizon 6 Cars selection is worth watching closely, because one new tune or update could shake this list again before long.
