The Mazda RX line represents the pinnacle of driving dynamics within the Japanese manufacturer’s portfolio, blending sporty aesthetics with accessible performance. From the original RX-7 to the current RX-8 and the modern RX-7 and RX-8 inspired models, this series has consistently captivated driving enthusiasts. Understanding the evolution of these models provides insight into Mazda’s commitment to the rotary engine and its pursuit of a perfect handling balance. This guide explores the history, specifications, and characteristics that define every Mazda RX model ever produced.
Heritage of the Rotary Engine
To discuss the Mazda RX series is to discuss the Wankel rotary engine, a technological marvel that defines the brand’s identity. Unlike traditional piston engines, the rotary engine delivers power through a triangular rotor, resulting in a compact, smooth, and high-revving powerplant. The RX-7, particularly, became legendary for its 13B rotary, producing impressive power figures while maintaining a light and balanced chassis. This engineering philosophy placed Mazda RX models firmly in the realm of driving purists, offering an experience distinct from conventional V8s or inline-six engines.
The Original RX-7: A Sports Car Icon
Launched in 1978, the first-generation RX-7 (SA22) established the template for the sports car segment. Its low-drag coupe design hid a potent 100 horsepower 10A rotary, which grew in displacement and output over three generations. The FC generation RX-7 is often cited as the model that perfected the formula, offering a naturally aspirated 13B producing up to 255 horsepower in later turbocharged variants. With its lightweight construction and near-perfect 50/50 weight distribution, the RX-7 delivered handling that felt telepathic, earning a devoted following that persists today.
The RX-8: The Modern Rotary Sports Car
Introduced in 2003, the RX-8 represented Mazda’s vision for the 21st century rotary sports car. Featuring a sleek, fastback design and a rear-hinged suicide door, the RX-8 housed the 13B-MSP Renesis engine, which utilized twin side exhaust ports to improve efficiency and power. Seating for four in a 2+2 configuration, it offered practicality without sacrificing its sporty credentials. The model became the spiritual successor to the RX-7, carrying the torch of the rotary engine into an era dominated by SUVs and turbocharged four-cylinders, though production ended in 2012 due to emissions regulations.
Revival and Modern Interpretations
Following the RX-8’s discontinuation, Mazda remained quiet on the rotary front for several years, fueling speculation about the platform’s future. Rumors of a rotary-powered MX-5 MiRF and a range-extended electric vehicle for the i-ACTIVSENSE platform hinted at the engine’s evolving role. More recently, the company has confirmed a multi-rotor rotary engine dedicated to series hybrid applications, signaling a potential return. While a direct RX-9 remains unconfirmed, the spirit of the RX line is very much alive in models like the MX-5 RF, which channels the driving purity the RX series is known for.
Key Specifications and Performance
Performance metrics vary significantly across the RX family, but a focus on driving dynamics remains constant. The RX-7 FC2S, for example, achieved a 0-60 mph time of approximately 5.3 seconds, while the RX-8 sprinted to the same mark in under 8 seconds. Handling characteristics, however, are where these models truly shine. The RX-8’s chassis, praised by automotive journalists worldwide, offers a level of precision that feels communicative and confidence-inspiring. Below is a comparison of key generations:
