Mazda RX-7 SA/FB

The first-generation Mazda RX-7 arrived on the scene in 1978, spanning two distinct series: the SA (1978-1980) and the FB (1981-1985). It was a true back-to-basics sports car, prioritizing a lightweight design and a focus on the joy of driving. Characterized by its sleek wedge shape and pop-up headlights (in the SA series), the RX-7 exuded sporty charm. But the heart and soul of this machine was its compact and high-revving rotary engine, offering a driving experience that set it apart from its piston-powered rivals. The RX-7 delivered thrills without relying on brute force, instead rewarding drivers with its agility and high-revving nature.




Mazda’s fascination with the rotary engine began well before the RX-7. Earlier models like the Cosmo (1967) and Luce (1969) showcased the potential of this unique engine design. However, it was the oil crisis of the 1970s that fueled a desire for a more efficient, performance-oriented sports car.

Enter the RX-7. Introduced in 1978, its goal was to deliver an affordable, lightweight, and exhilarating driving experience centered around the rotary engine. The result was a hit! The RX-7’s combination of balance, handling, and rev-happy engine captivated drivers worldwide. It established Mazda as a serious contender in the sports car market and solidified the rotary engine’s place in automotive history.

The Mazda RX-7 SA/FB embodies a clean and purposeful design language. Its wedge-shaped profile and iconic pop-up headlights (on the SA series) immediately evoke a sporty personality. The FB series maintained the overall shape but introduced retractable headlights for a slightly more refined look. The RX-7’s compact dimensions and purposeful stance give it an undeniable presence on the road. Later FB models, especially the GSL-SE, featured subtle fender flares and more pronounced spoilers, adding a touch of muscularity to the design. Overall, the RX-7 exudes a timeless sports car aesthetic that balances simplicity with a sense of dynamic energy.



RX-7 SA/FB Interior

The RX-7’s interior puts the driver front and center. The cockpit is simple yet functional, with a clear focus on the essentials. Supportive seats, particularly in sport-oriented trims, provide a good driving position and hold you in place during spirited maneuvers. Gauges are large and easy to read, adding to the sporty ambiance. As with most sports cars of the era, rear seat space is limited and best considered for occasional use or extra storage. Depending on the trim level, you might find features like power windows, a sunroof, and various audio system options, adding a touch of convenience to the otherwise uncluttered cabin.

The beating heart of the Mazda RX-7 SA/FB is its Wankel rotary engine. This unique engine design provides smooth power delivery, loves to rev high, and creates a distinctive soundtrack unlike anything with pistons. Two primary engine options existed: the 12A and the larger 13B. Power figures varied throughout the years and depending on the market, but both engines delivered a thrilling driving experience thanks to their compact size and free-revving nature. Despite their small displacement, rotary engines could punch above their weight class in terms of power output and driving excitement.

Driving Experience

The Mazda RX-7 SA/FB is a true driver’s car that emphasizes engagement and a thrilling connection between driver and machine. Its lightweight construction, balanced handling, and unique rotary engine make it a joy to pilot on winding roads and a blast to experience at the limit of its capabilities.


The RX-7’s steering is a highlight, offering precise inputs and excellent feedback from the road. It communicates exactly what the front wheels are doing, inspiring confidence during cornering and making it easy to place the car exactly where you intend.


Light and agile are the keywords for the RX-7’s handling. Thanks to its low weight and near-perfect weight distribution, it changes direction with delightful eagerness. Cornering is remarkably flat, with minimal body roll. While not focused on outright grip, it’s the exceptional balance and playful nature that makes the RX-7 so rewarding to drive enthusiastically.


The RX-7’s acceleration is about high-revving thrills rather than brute force. Rotary engines don’t deliver a wallop of low-end torque, but the power builds smoothly and linearly as the revs climb, culminating in a satisfying surge towards the redline. This encourages you to work the gearbox and keep the engine singing in its sweet spot. The later turbocharged GSL-SE models offered notably more power for a significant boost in straight-line performance.


Braking performance is adequate for the weight of the car. Larger disc brakes were available on some models, providing improved stopping power. Upgrading brake components is a popular modification for RX-7s that see track use or very spirited driving.


A unique aspect of the RX-7 experience is the sound of the rotary engine. Its high-pitched mechanical whir gets smoother and more intense as the revs rise. Enthusiasts adore this distinctive soundtrack, and it adds to the excitement of pushing the car hard.

Driver engagement

The RX-7 demands active participation from the driver. It thrives on being driven hard, rewarding you with a constant stream of feedback through the steering wheel, seat, and pedals. This car is less about isolating you and more about connecting you to the process of driving. If you’re looking for a car that demands attention and delivers a pure driving experience, the RX-7 is sure to leave a smile on your face.


Driver Aids and Safety Features

An optional limited-slip differential improved traction by sending power to the wheel with the most grip, which aided handling and acceleration. Overall, the RX-7’s philosophy prioritizes driving involvement, meaning it’s up to the driver to be aware of the car’s limits and react accordingly.
