The Mazda RX-7, a name synonymous with rotary engine innovation and sleek sports car design, has captivated enthusiasts for decades. Finding the "best" year of the RX-7 depends heavily on individual priorities: performance, reliability, aesthetics, or collectibility. This guide provides a comprehensive overview of the RX-7 generations, highlighting the strong and weak points of each, to help you make an informed decision.

Mazda RX-7 Model Year Overview

Generation (Years) Key Features/Considerations Potential Issues/Years to Avoid
First Generation (FB/SA22C, 1979-1985) Lightweight, carbureted 12A rotary engine, iconic pop-up headlights, simple and engaging driving experience. Carburetor issues, early models prone to rust, lower power output compared to later generations. 1979-1980 models, especially in regions with harsh winters.
Second Generation (FC3S, 1986-1991) More powerful turbocharged 13B rotary engine (some models), improved suspension, more refined interior, available in coupe and convertible. Complex turbo system prone to failures, potential for overheating, apex seal wear. 1986-1988 models, particularly those with the original turbocharger design.
Third Generation (FD3S, 1993-1995 US Market, 1991-2002 Japan) Sequential twin-turbocharged 13B-REW rotary engine, stunning design, advanced suspension, exceptional handling. High maintenance costs, complex sequential turbo system, apex seal wear exacerbated by high boost, overheating. All years, but especially those with neglected maintenance.

Detailed Explanations

First Generation (FB/SA22C, 1979-1985): The original RX-7 offered a pure and unfiltered driving experience. Its lightweight chassis and responsive 12A rotary engine made it a joy to drive, even with its relatively modest power output. The simplicity of the design is a major draw for those who enjoy tinkering and maintaining their own cars. However, carburetor issues were common, and early models are particularly susceptible to rust, especially in areas where road salt is used.

Key features:

  • 12A Rotary Engine: A carbureted rotary engine offering a unique driving experience with smooth power delivery and a distinctive sound.
  • Lightweight Design: Contributed to agile handling and responsive performance.
  • Pop-up Headlights: A classic sports car design element.
  • Simple Mechanics: Relatively easy to work on and maintain compared to later generations.

Potential Issues/Years to Avoid:

  • Carburetor Problems: Carburetor tuning and maintenance can be challenging.
  • Rust: Early models (1979-1980) are prone to rust, especially in areas with harsh winters.
  • Lower Power Output: Compared to later generations, the 12A engine produces less horsepower.

Second Generation (FC3S, 1986-1991): The FC RX-7 represented a significant step forward in terms of performance and refinement. The introduction of a turbocharged 13B rotary engine (in some models) boosted power significantly, while improved suspension and a more sophisticated interior enhanced the overall driving experience. Available in both coupe and convertible configurations, the FC offered greater versatility than its predecessor. However, the complex turbo system was prone to failures, and overheating could be an issue.

Key features:

  • 13B Rotary Engine (Turbocharged): Increased power and torque compared to the first generation.
  • Improved Suspension: Enhanced handling and ride quality.
  • More Refined Interior: More comfortable and modern interior compared to the FB.
  • Available in Coupe and Convertible: Offered greater versatility.

Potential Issues/Years to Avoid:

  • Turbo System Failures: The turbocharger system can be complex and prone to issues.
  • Overheating: Overheating can be a problem, especially in hot climates or with aggressive driving.
  • Apex Seal Wear: Rotary engines are known for apex seal wear, which can lead to reduced compression and engine failure. 1986-1988 models with the original turbocharger design are more susceptible.

Third Generation (FD3S, 1993-1995 US Market, 1991-2002 Japan): The FD RX-7 is widely considered the pinnacle of RX-7 design and performance. Its stunning exterior, sequential twin-turbocharged 13B-REW rotary engine, and advanced suspension made it a true sports car icon. The FD's exceptional handling and exhilarating performance cemented its place in automotive history. However, it's also the most complex and demanding RX-7 to maintain. High maintenance costs, a complex sequential turbo system, and the potential for apex seal wear are significant concerns.

Key features:

  • Sequential Twin-Turbocharged 13B-REW Rotary Engine: Delivers impressive power and torque with minimal turbo lag.
  • Stunning Design: Widely regarded as one of the most beautiful sports cars ever made.
  • Advanced Suspension: Provides exceptional handling and roadholding.
  • Lightweight Construction: Contributes to agile performance.

Potential Issues/Years to Avoid:

  • High Maintenance Costs: The FD RX-7 requires regular and often expensive maintenance.
  • Complex Sequential Turbo System: The sequential turbo system is complex and prone to issues.
  • Apex Seal Wear: Apex seal wear is a common problem, especially with high boost levels.
  • Overheating: Overheating can still be an issue, especially with modifications or aggressive driving. All years are potentially problematic if maintenance is neglected.

Frequently Asked Questions

  • Which RX-7 is the most reliable? The first-generation (FB) RX-7 is generally considered the most reliable due to its simpler design and carbureted engine.

  • Which RX-7 is the fastest? The third-generation (FD) RX-7 is the fastest, thanks to its sequential twin-turbocharged engine and lightweight design.

  • What are apex seals and why are they important? Apex seals are critical components in a rotary engine that seal the combustion chambers. Wear or failure of apex seals can lead to reduced compression and engine failure.

  • Is the RX-7 expensive to maintain? Yes, especially the second and third-generation models, due to the complexity of the turbo systems and the potential for apex seal wear.

  • Can I daily drive an RX-7? It's possible, but not recommended, particularly for the FD. Reliability and maintenance demands make them better suited as weekend cars.

  • Which RX-7 is the most collectible? The third-generation (FD) RX-7 is generally considered the most collectible due to its iconic design and limited production, particularly the Spirit R models.

Conclusion

Choosing the "best" Mazda RX-7 depends on your priorities and budget. The first generation offers simplicity and affordability, the second generation provides a balance of performance and refinement, and the third generation delivers unparalleled performance and style, but at a higher cost. Regardless of your choice, thorough research, a pre-purchase inspection, and a commitment to proper maintenance are essential to enjoying the unique experience of owning an RX-7.
