Overview
1991 Mazda #55 Mazda 787B appears on the official Forza Horizon 6 car list as a R Class (track-focused) entry in the base roster. This page focuses on what the car actually means for everyday players: how it tends to drive in its class, where it fits inside Forza Horizon 6's Japan setting, how to think about a starting tune, and which other roster entries it naturally compares against.
If you found this page while searching for a single Mazda model in Forza Horizon 6, you are in the right place. Everything below is built around the official list fields (year, class, pack, manufacturer) plus plain-language player notes. We do not invent horsepower numbers, hidden upgrade paths, or unlock guarantees that the official list has not confirmed.
Background and Forza Horizon 6 context
The #55 787B is the Mazda Le Mans-winning prototype that took the overall victory at the 1991 24 Hours of Le Mans, becoming the only rotary-powered car ever to win Le Mans and the first Japanese manufacturer to win overall. The R26B four-rotor engine produced around 700 hp at 9,000 rpm and is famous for its distinctive scream. On the official Forza Horizon 6 car list this 1991 Mazda entry sits in the R Class (track-focused) bracket inside the base roster, which is the placement players come to this page expecting to confirm against the public source. Inside the same R Class (track-focused) bracket, the closest comparison roster entries for players are 1990 Alfa Romeo SE 048SP and 1989 Ferrari F40 Competizione, which is the R Class (track-focused) peer group this car is usually weighed against. The JDM tag fits the wider Japanese setting of Forza Horizon 6, where this make tends to be a focal point of cruise lobbies and theme nights.
Driving feel in Forza Horizon 6
Mazda 787B was the only rotary-engined car ever to win the 24 Hours of Le Mans (1991). The R26B four-rotor wankel makes around 700hp at 9,000rpm. In R-class events on Forza's long road circuits the 787B behaves like the Le Mans prototype it is; the rotary's smooth power delivery and high rev limit are the dominant chassis variables.
Where it shines
R class is at home on the dedicated road circuits and any event where downforce, tire heat and brake bias can be used. Avoid running R class on tight street routes where the car cannot stretch.
Tuning starting point
R class needs an aero-first mindset. Set differentials around how aggressively you trail-brake, and rotate compounds based on the track surface. Rear-wheel-drive cars want a softer rear and careful throttle on corner exit; pay attention to rear tire pressure especially on long Japan map straights.
These are general starting points only, not a guaranteed competitive setup. Forza Horizon 6 community tunes that already have hundreds of downloads are usually a faster route than building from scratch, especially if you are not sure of the car's drivetrain or aero behaviour yet.
How to get 1991 Mazda #55 Mazda 787B
This car is listed without an add-on label on the official Forza Horizon 6 source, so we treat it as part of the base roster. Forza Horizon 6 launches on May 19, 2026, and before that date the public Autoshow may not surface every base-roster car yet — players asking 'how do I get this car, it is not in the Autoshow?' on Reddit or the Forza forums usually find the answer is 'wait for launch day or a post-launch update'. After launch, base-roster cars are normally available through credits in the Autoshow, Wheelspins, Festival Playlist rewards, or the in-game showcase that introduces new vehicles.
