Lock-up torque converter for improved fuel efficiency at highway speeds.
Crash Test Data Availability:
Limited public crash test data available for this specific model year from modern standards, but designed with crumple zones and a reinforced passenger cell.
Braking System:
Power-assisted disc brakes, front: vented; rear: solid. Anti-lock Braking System (ABS) was an option on some models.
Suspension Handling:
Independent front and rear suspension contributed to stable handling characteristics.
Seatbelts:
Three-point inertia reel seatbelts
Rollover Protection:
Reinforced A-pillars and A-pillar hoop for structural integrity.
Audio System:
Factory-installed AM/FM stereo radio with cassette player, often with graphic equalizer and amplifier.
ABS Availability:
Optional Anti-lock Braking System (ABS) available on select models, enhancing braking control.
Cruise Control:
Standard or optional cruise control system for highway driving.
Oil Change Interval:
Typically every 5,000 miles (8,000 km) or 6 months, whichever comes first. Severe service may require more frequent changes.
Spark Plug Replacement:
Refer to manual; rotary plugs differ from piston engines and require specific intervals based on wear.
Timing Belt Alternatives:
Rotary engines do not have timing belts; they use a chain or a direct drive system for the eccentric shaft.
Engine Oil Type:
API SG or SH, SAE 10W-30 or 10W-40. Higher viscosity may be recommended for hot climates. Check manual for specific recommendations.
Engine Oil Capacity:
Approximately 5.2 quarts (4.9 liters) with filter change for the 13B rotary engine.
Coolant Type:
Mazda/Ford Super Coolant (blue) or equivalent ethylene glycol-based coolant with proper corrosion inhibitors for aluminum engine components. 50/50 mix with distilled water.
Transmission Fluid Manual:
API GL-4 or GL-5, SAE 75W-90 gear oil. Check manual for exact specification.
Transmission Fluid Automatic:
Mazda ATF Type T-IV or equivalent DEXRON-III compatible fluid.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Rotary Engine Specific:
Apex seal wear is a primary concern, leading to loss of compression. Requires diligent oil maintenance and avoiding excessive detonation. Heat management is critical.
Cooling System Concerns:
Overheating can be an issue due to the compact nature of the rotary and potential for radiator blockage or fan failure. Regular flushing and inspection are vital.
Fuel System Concerns:
Fuel injectors and pressure regulators can become clogged or fail over time. Ignition system components (coils, plugs, wires) require regular inspection.
Period Awards:
