Engine Type:
Mazda Rotary (Wankel)
Engine Displacement Rx2:
982 cc (0.98 L) 10A
Engine Displacement Rx3:
982 cc (0.98 L) 10A; later models may have used variations or larger displacement rotary engines in some markets (e.g., 12A)
Horsepower Rx2 10A:
Approximately 110-130 PS (108-128 hp) depending on tuning and emissions equipment.
Torque Rx2 10A:
Approximately 140-150 Nm (103-111 lb-ft) depending on tuning.
Fuel Delivery:
Carbureted (e.g., Hitachi, Weber) or Fuel Injection depending on model year and market.
Apex Seals:
Critical wear item requiring specific lubrication and maintenance; manual provides detailed inspection and replacement procedures.
Transmission Type Common:
4-speed Manual
Transmission Type Optional:
3-speed Automatic (less common, especially on performance variants)
Clutch Type:
Single Dry Plate
Transmission Fluid Type:
Likely GL-4 gear oil (specific grade such as 80W-90 or 85W-90, manual to confirm)
Crash Test Data:
Limited official crash test data available for this era; safety features were basic by modern standards.
Braking System:
Front Disc Brakes, Rear Drum Brakes (standard on most models); power assist may be optional or standard depending on trim.
Seatbelts:
Lap belts standard, shoulder belts may be optional or standard on later models/higher trims.
Radio Type:
AM/FM Radio, often with a single speaker. Cassette tape players were rare or aftermarket additions in this era.
Power Steering:
Optional on many models, standard on higher trims or later production years.
Connectivity Features:
None by modern standards. Focus was on mechanical systems and basic electrical functions.
Oil Change Interval:
Typically every 3,000-5,000 miles or 3-6 months, but specific interval depends on oil type and driving conditions. Rotary engines require specific oil consumption for lubrication.
Spark Plug Replacement:
Depends on plug type; platinum or iridium plugs last longer. Original plugs likely required replacement every 10,000-15,000 miles. Manual provides specific recommendations.
Engine Oil Type Rotary:
Specific engine oil with appropriate additive package for rotary lubrication (manual will detail, often a 20W-50 or similar high-detergency oil).
Coolant Type:
Ethylene Glycol based coolant, typically a 50/50 mix with distilled water. Manual will specify capacity and type.
Apex Seal Wear:
Premature wear can occur if engine is not properly maintained or if subjected to excessive detonation. Leading cause of engine failure if not addressed.
Carburetor Issues:
Tuning and maintenance of Hitachi or Solex carburetors can be complex, requiring specialized knowledge.
Ignition System:
Distributor, coil, and plug wires require regular inspection and maintenance for optimal rotary engine performance.
Oil Injection System:
Some models featured an oil injection system; if malfunctioning, it can lead to accelerated apex seal wear. Manual details its operation and maintenance.
Rotary Pioneering:
Mazda's commitment to the rotary engine development, making them unique in the automotive industry.
Rx2 Introduction:
Launched in 1970, positioned as a sporty compact car, often seen as the successor to the Familia Rotary.
Rx3 Introduction:
Launched in 1971, also featuring rotary power, sharing many mechanical components with the RX-2 but with distinct styling and body options.
Production Era:
RX-2: 1970-1972; RX-3: 1971-1978.
