Our Methodology

How We Ranked These Cars

The rankings above are based on stock performance data — every car shown is completely untuned, straight from the Autoshow. If a car ranks #1 for Speed in stock form, it has a natural advantage that's hard to overcome.

At ForzaLabs, we built an automated system that collects every upgrade and tuning option for every car in Forza Horizon 5 — thousands of parts across hundreds of vehicles.

Beyond Stock

Stock Rankings Are Only the Starting Line

In competitive online racing, nobody runs stock. The right combination of upgrades can transform a mid-tier car into a class leader. The question isn't "which car is best stock" — it's "which car is best after the optimal tune for my race?"

That's exactly what our full database answers. Enter your race restrictions — class limit, drivetrain rules, weather conditions — and we'll show you the optimal car and build.

Why Speed Matters

In Forza Horizon 5, the Speed stat reflects raw top-end velocity. Tracks with long straights reward cars that pull away at the top end.

Budget vs. Premium Picks

If you're just starting out, the 1986 Bmw M635csi at 250,000 CR is a strong entry point. The 1990 Mercedes-Benz 190e 2.5- 16 Evolution Ii leads at 6.2 Speed, but costs 150,000 CR.
