Speed runs in Forza Horizon 6 are a bit messy right now, and honestly, that's part of the fun. Players aren't only grabbing the obvious hypercars anymore. Some of the quickest FH6 Cars are coming from strange builds, Forza Edition oddities, and lightweight machines that look wrong on paper but fly on the road. This list is about top speed only. Not lap times, not cornering, not whether the car feels nice through traffic. If it can hold a huge number on a long straight with the right tune, it belongs in the conversation.
Rank 1: Toyota AE86 Sports Tradition
The 1985 Toyota Sprinter Trueno GT Apex Sports Tradition is the car people keep talking about, mostly because it shouldn't be sitting at the top. With a serious speed build, it has been pushed to around 324.1 mph, which puts it well ahead of everything else tested so far. The trick is not magic. It's a wild mix of a 2JZ swap, all-wheel drive, race turbo with anti-lag, slick tyres, light rims, race differential, and heavy weight reduction. Remove the rear wing, fit the right Toyota kit, use rally springs, then stretch the gearing until the car stops fighting itself. It's not a normal AE86 anymore. It's a tiny missile, and that's why players love it.
Rank 2: Nissan GT-R R35 Forza Edition
The Nissan GT-R R35 Forza Edition takes second place with runs near 306 mph. That's not a small number, especially for a car many players first treat as a drag build. The all-wheel-drive grip helps it launch hard, and once the gearing is sorted, it keeps pulling far longer than you'd expect. It doesn't feel as silly as the AE86 either. You can use it for speed traps, drag races, and plenty of casual open-road messing about. That makes it one of the more useful fast cars, not just a one-trick garage queen.
Rank 3 and Rank 4: Venom F5 and MX-5 Forza Edition
The Hennessey Venom F5 lands in third with a top speed around 305 to 306 mph. Most players expected it to be the king because, well, that's what the real car was built for. It's still brutally fast and doesn't need much explaining. Tune it cleanly and it'll cross 300 mph without drama. Just behind it sits the Mental Mazda MX-5 Forza Edition at roughly 295 to 296 mph. That one feels more ridiculous. It's light, sharp off the line, and built around a big power-to-weight punch. Getting the higher number takes a cleaner run, but even at 295 mph it's a proper shock.
Rank 5: Lotus Evija Forza Edition and Porsche 917 Forza Edition
Fifth place is shared by the Lotus Evija Forza Edition and the Porsche 917 Forza Edition, both reaching about 294 mph with dedicated top-speed setups. The Evija brings instant electric torque, so it gets up to speed fast and stays stable when the road opens up. The Porsche feels different. It has that old racing shape, but in FH6 it can be tuned into something far more extreme than its classic looks suggest. Neither car is quite at the level of the front runners, yet both are quick enough to embarrass plenty of famous supercars.
Picking Your Next Speed Build
The Koenigsegg Agera RS still deserves respect, even if it's no longer sitting on the throne like it did in older Horizon talk. FH6 tuning has changed the pecking order, and players are still finding new combinations every week. If you're planning to build several speed cars, upgrades get expensive fast, so browsing cheap Forza Horizon 6 Cars can help you save credits for engine swaps, tyres, and tuning parts. Right now, though, the AE86 Sports Tradition is the car to beat, and that's exactly the kind of weird result that makes Horizon testing worth doing.
