Dirt tier list

Best Dirt B cars in Forza Horizon 6

B 600 Dirt is the most-raced restriction in the early Festival Playlist (the current Trail Mix Modern Rally championship runs at B). The class is dominated by Modern and Retro Rally homologation cars: short wheelbase, AWD, light enough to keep mechanical grip on rough surface transitions. Picks below are ranked for B 600 dirt builds; lower PI targets shift the ordering, see each entry's build notes.

How we ranked these

Cars natively in B class with proven rally lineage get priority. AWD weighted over RWD given FH6's new tuning realities (rally diff is favoured even on road, and brakes now matter on rough downshifts). Power is capped low at B, so weight-to-power and chassis composure beat outright BHP. Early FH6 meta is fluid; we update each Series reset.

AWD · Modern Rally · 2.0L Turbo I4

The cleanest B-class rally platform in the game. AWD, 1540 kg, and a 4B11T that takes a soft tune without losing PI to power, so points go to suspension, brakes and aero.

Lighter than the Evo X with the same AWD launch and a stronger braking platform. The GD-chassis Impreza is a Forza staple for a reason; it transitions well under throttle on undulating dirt.

Short wheelbase plus AWD plus low weight (1310 kg) makes the GR Yaris the rotation specialist of the class. Stock PI 558 leaves the biggest tuning budget of any AWD pick.

Sits at exactly B 600 stock, so you can race it nearly untouched. Light, mechanical, and the Group A lineage still translates to good rough-road behaviour.

AWD · Retro Rally · 2.1L Turbo I5

The original Group B AWD. Heavier than the Yaris but the long-stroke five gives it standout drive out of corners; reward, not a beginner pick. Watch the new mechanical-balance display, the Quattro likes a small rearward bias for rally.

Honorable mentions

1977 Ford 5 Escort RS1800 MkIIB · RWD
RWD and 980 kg. Off the podium for B 600 dirt because AWD wins the launch, but it is the most rewarding car on the list if you want a drive-with-the-throttle build.
1986 Lancia Delta S4B · AWD
Twincharged Group B icon. Sits a class above stock; tune down to B and it competes, but the tighter PI budget hurts harder than the Audi.
1995 Mitsubishi Lancer Evolution III GSRB · AWD
Older Evo chassis with the same drivetrain story as the Evo X. Pick this when you want the lower wheelbase numbers.
