Safety Ratings:
NHTSA ratings for 1986 models are generally unavailable in a standardized format comparable to modern testing. However, vehicles of this era generally lacked advanced safety features.
Active Safety Features:
Four-wheel disc brakes (standard on most models), power-assisted steering
Passive Safety Features:
Seat belts, reinforced chassis structure
Infotainment System:
Basic AM/FM/Cassette stereo system, optional equalizer, power antenna.
Driver Assistance Features:
Limited; primarily focused on mechanical systems. ABS (Anti-lock Braking System) became available on later models or as an option.
Connectivity Features:
None (modern sense); primarily focused on vehicle operation and basic comfort features.
Oil Change Interval:
Every 3,000-5,000 miles or 3-6 months (recommendation based on driving conditions; check manual for specifics)
Spark Plug Replacement Interval:
Refer to manual for specific interval based on plug type (e.g., platinum or standard) and engine condition. Rotary apex seals are critical wear items.
Engine Oil Specification:
API SG or SH, SAE 10W-30 or 10W-40 (check manual for specific recommendations, especially for rotary engines requiring specific oil properties)
Coolant Specification:
Mazda premium coolant or equivalent, ethylene glycol-based, typically a 50/50 mix with distilled water

Known Issues:
Rotary engine apex seal wear (requiring rebuilds if not maintained properly), oil seal leaks, vacuum hose degradation leading to performance issues, brake caliper seizing, rust, aging electrical components, turbocharger issues on Turbo II models.
Brand Heritage:
Mazda has a long history of producing innovative and driver-focused vehicles, with a particular emphasis on rotary engine technology since the introduction of the Cosmo in 1967.
Model Evolution To 1986:
The 1986 RX-7 represents the second generation (FC) of the RX-7 lineage. It replaced the first-generation (SA/FB) model with a more modern design, improved aerodynamics, and a focus on performance and handling. The FC was often referred to as the 'Savanna RX-7' in Japan. It offered both naturally aspirated and turbocharged (Turbo II) variants.
Production Period:
The second generation RX-7 (FC) was produced from 1985 to 1992.
Manufacturing Location:
Hiroshima, Japan
