"A "banshee rotary". The sound of "seven thousand cats being stung by seven thousand wasps." These are just two of the more colorful descriptions from journalists about the 1991 Mazda #55 Team Mazdaspeed 787B’s inimitable 690-horsepower Wankel-type rotary engine. That motor and it’s unmistakable, gloriously chaotic noise is coming to bring a full aural and automotive assault to every track in Forza Motorsport 6. Of course, if you’re a traditionalist, you’ll first want to hit Le Mans and, in particular, the Mulsanne Straight, where the 787B is most at home. The 787B and its Group C brethren regularly hit speeds north of 215 mph, which eventually caused the Le Mans organizers to add chicanes in 1990. And in 1991, the 787B won Le Mans itself, only for Mazda to find its star car banned after a rules change banned Wankel-type rotaries from competition. The 787B now sits in a place of honor at Mazda’s Hiroshima museum and for good reason: Since the team’s victory twenty years ago, no other Japanese manufacturer has managed to win Le Mans, a fitting legacy for a car that needs to be seen, driven, and heard to be believed."

—Official description

The 1991 Mazda 787B is a prototype race car by Mazda.

It appears in Forza Motorsport 4 as part of the February American Le Mans Series Pack, in Forza Motorsport 5 as part of the VIP Membership and all subsequent Motorsport series titles.

Variants

The 787B has been featured in two livery variants, with the #55 being featured in all titles, and both being present in Forza Motorsport 6 and Forza Motorsport 7

• 1991 Mazda #18 Mazdaspeed 787B (Forza Motorsport 6 and Forza Motorsport 7) - abbreviated as "#18 Mazda 787B"
• 1991 Mazda #55 Mazda 787B (All titles) - abbreviated as "#55 Mazda 787B" or "Mazda #55 787B"

Synopsis

The 787B is a Group C sports prototype race car built by Mazda for use in the World Sportscar Championship, All Japan Sports Prototype Championship, and the 24 Hours of Le Mans from 1990 to 1991.

The Mazda 787B is unique in that its victory at the 1991 24 Hours of Le Mans remains the only victory by a Japanese marque until 2018 with Toyota's TS050 Hybrid and the only victory by a car without a reciprocating engine design.

The Mazda 787B uses Mazda's 2.6 L (2,616 cc) 4-rotor engine, codenamed R26B. It produces 690 hp (515 kW) and 448 ft·lb (607 N·m) of torque.

Trivia

• The Mazda Furai concept car bears the #55 number of the winning Mazda #55 Mazda 787B.
• The 2.6L 4 Rotor - Racing engine swap originates from this car.
• The #18 Mazdaspeed 787B first featured in Forza Motorsport 6, has seemingly identical specifications and pricing to its #55 counterpart, however upon further inspection, the in-game stats reveal that the #18 possesses weaker braking performance, and conceives fewer G-forces, lowering the overall PI by one, from the #55. This strange variation has been omitted since Forza Motorsport 7.
• In Forza Motorsport (2023), it has a weight statistic of 1995 lb (905 kg).
