Real-World History

Mazda built the RX-3 (also known as the Savanna in Japan) from 1971 to 1978 as a rotary-powered competitor to small American and European coupes. The 12A two-rotor engine displaced just 1.1 liters but produced 120 horsepower — competitive with the inline-fours of the era from much larger displacements. Mazda used the RX-3 to establish rotary engine credentials in Japanese touring car racing, and the car won the All-Japan Touring Car Championship multiple times in the early 1970s.

In the Forza Horizon Series

The RX-3 received a Forza Edition treatment for Horizon 6, which adds skill-multiplier perks and a unique livery to the standard chassis. Earlier Forza titles included the RX-3 only as a pack DLC, so its inclusion as a Forza Edition is a meaningful elevation for rotary fans.

The S102A Forza Horizon car appears across 1 entries: FH6. As a S102A Forza Horizon car entry, it sits in the C-class bracket at stock tune.

Tuning Notes

The lightweight chassis (under 1,000 kilograms) responds dramatically to tire upgrades; many builds reach class-competitive lap times with stock-displacement tunes plus stickier rubber. Avoid bridge-port or peripheral-port engine modifications that would push power past 200 horsepower — the original transmission and differential are not engineered for that load. The rotary exhaust note is one of the in-game audio highlights worth experiencing without modification.

For the S102A Forza Horizon car, the most successful community blueprints share a few common adjustments: balanced aero, tire compound matched to event surface, and gearing tuned for the specific Festival Playlist scenario rather than maximum top speed. The S102A Forza Horizon car responds best when the tuner respects the chassis's inherent character rather than trying to mask it with extreme settings.

Trivia & Lore

Real RX-3 prices have climbed alongside other 1970s Japanese coupes; mid-condition examples now bring 80,000 US dollars in the United States despite never being officially sold there in significant numbers.
