Which Mazda Models Use Rotary Engines?
2 Answers
Mazda models that utilize rotary engines include: COSMO-SPORT-110s, Savanna, Luxury Edition COSMO-SPORT-CosmoAP, MAZDA-RX-7-FD3s, and Mazda-787B. Below is relevant information about rotary engines: 1. Mechanical Differences: Rotary engines, like traditional reciprocating engines, rely on the expansion pressure generated by the combustion of air-fuel mixture to produce rotational force. The difference lies in how they utilize this expansion pressure. 2. Advantages: Rotary engines eliminate useless linear motion, resulting in smaller size, lighter weight, lower center of gravity, greater power output, and reduced vibration and noise compared to reciprocating engines of the same power.
In my youth, I chased after Mazda's classic models, and their rotary engine series truly evokes nostalgia. It all started with the 1967 Cosmo Sport, which paved the way, followed by the RX family. Models like the RX-2 and RX-3 gained popularity in the 70s, while the RX-4 and RX-5 each had their unique characteristics. However, the real household name was the RX-7, especially the FB and FC models in the 80s and the FD in the 90s, which won fans over with their lightweight design and superb handling. The RX-8 then took over in 2003 and remained in production until its discontinuation in 2012. The rotary engine was smooth and powerful, but its high fuel consumption and expensive maintenance were significant drawbacks, leading Mazda to shift toward conventional engines. Today, if you're looking for a used model, these cars can still be found at auctions, holding considerable historical value. The rotary engine was once the soul of Mazda, but times have changed, leaving it only in our memories.
