Approx. 1350 kg (2976 lbs)
Curb Weight Na:
Approx. 1250 kg (2756 lbs)
Crash Test Data Availability:
Limited public data for this era, but known for a robust chassis for its class.
Braking System:
Four-wheel disc brakes, often with ABS (Anti-lock Braking System) as an option or standard on Turbo II.
Suspension Dynamics:
Designed for high-speed stability and predictable handling, contributing to active safety.
Seat Belts:
Three-point seat belts, often with pretensioners.
Body Structure:
Reinforced A-pillars, B-pillars, and side impact protection.
Audio System:
Factory-installed cassette player and AM/FM radio, often with optional CD player integration.
Climate Control:
Manual or automatic climate control systems depending on trim level. Focus on HVAC component parts.
ABS:
Available on most models, crucial for braking performance and safety.
Cruise Control:
Standard on most models.
Oil Change Interval Rotary:
More frequent than piston engines due to the nature of rotary lubrication. Mazda typically recommended every 3,000-5,000 miles or 3-4 months, whichever comes first.
Spark Plug Replacement:
Specific rotary spark plugs required, replacement interval typically around 15,000-30,000 miles, depending on usage and plug type.
Timing Belt Equivalent:
Rotary engines do not have a timing belt. They use a chain or direct drive for the rotor eccentric shaft.
Engine Oil Viscosity:
Refer to manual; typically 10W-30 or 10W-40, with specific API service classifications. Special attention to oil quality and type is crucial for rotaries.
Coolant Type:
Ethylene glycol based coolant, typically a 50/50 mix with distilled water. Specific Mazda coolant is recommended.
Transmission Fluid Manual:
GL-4 Gear Oil, typically 75W-90 or 80W-90.
Transmission Fluid Automatic:
Dexron III/Mercon compatible ATF.
Apex Seal Wear:
The primary concern with rotary engines is apex seal wear. Regular maintenance, proper warm-up/cool-down, and avoiding detonation are critical. This manual helps identify replacement seals.
Oil Consumption:
Rotary engines naturally consume a small amount of oil for lubrication of the rotor housings. Excessive consumption indicates potential seal or engine issues.
Cooling System Efficiency:
Rotary engines can run hotter than piston engines. Ensuring the cooling system is pristine is vital to prevent overheating, especially the Turbo II.
Mazda Rotary Legacy:
Mazda's exclusive commitment to the rotary engine spans decades, with the RX-7 being its most iconic sports car application.
Fc Generation Launch:
The FC generation (S5 chassis for 1989-1992) received updates including revised styling, improved engine management, and a more refined interior over its predecessor (SA22C).
Fc Facelift S5:

Japan
Car And Driver Tenbest:
The FC generation RX-7, particularly the Turbo II, was a frequent recipient of Car and Driver's '10Best' lists during its production run, recognizing its performance and handling.
Car Of The Year Contenders:
Often considered a contender in its class for sports car of the year awards by various automotive publications.
