D (0–400 PI) is one of the most competitive tiers in FH6 online racing. These five cars post the highest Speed ratings in class.
D394 
The undisputed Speed champion in this group. A natural advantage that's hard to overcome, even with a perfect tune on a weaker platform.
D382 
A strong Speed contender that's remarkably close to the top. Balanced and versatile across multiple track types.
D381 
Pairs high Speed with competitive all-around performance — a rare combination. An excellent all-rounder that doesn't force trade-offs.
D388 
A great mid-price option with Speed that punches above its weight. Lower PI leaves significant tuning headroom.
D267 
The most accessible car on this list with Speed that holds its own against pricier competition. Ideal for budget builds.
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 6 — thousands of parts across hundreds of vehicles.
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.
Stop guessing which car to bring. Search our complete upgrade database to find the highest-performing build for any class, any restriction, any event.
