🛡️ Safety Features

Crash Test Results:

As a 1990s sports car, formal crash test ratings comparable to modern standards are limited. Focus was on structural integrity and occupant protection for the era.

Braking:

Four-wheel disc brakes, optional Anti-lock Braking System (ABS)

Airbags:

Driver-side airbag standard, optional passenger airbag

Restraint System:

Seat belts, reinforced body structure.

💡 Technology Features

Audio System:

Factory premium audio system (e.g., Bose or Clarion), typically with cassette player and AM/FM radio. Some models may have optional CD players.

ABS:

Anti-lock Braking System (ABS) was available, providing enhanced braking control.

Diagnostic Ports:

OBD-I diagnostic port for engine code retrieval (specific to Mazda protocols of the era).

ECU:

Electronic Control Unit (ECU) managing fuel injection, ignition timing, and turbocharger control. The manual covers ECU diagnostics and troubleshooting.

🔧 Maintenance

Oil Change Interval:

Every 3,000-5,000 miles or 3-6 months, whichever comes first. Rotary engines are oil-hungry and benefit from frequent changes.

Spark Plug Interval:

Every 15,000-30,000 miles depending on plug type and driving conditions.

Timing Belt Equivalent:

Rotary engines do not have timing belts; they use chain or gear-driven components. Refer to manual for specific inspection and maintenance intervals for these components and apex seals.

Coolant Type:

Ethylene glycol based antifreeze, 50/50 mix with distilled water. Refer to manual for specific Mazda coolant recommendations.

Brake Fluid Type:

DOT 3 or DOT 4 brake fluid (check manual for exact specification and compatibility).

Rotary Engine Wear:

Apex seal wear is a common concern. Symptoms include loss of compression, hard starting, and rough idle. Regular oil changes and proper engine warm-up/cool-down are crucial.

Sequential Turbo Failure:

Failure of the primary or secondary turbocharger, or associated solenoids and wastegates, can impact performance. Proper maintenance and avoiding prolonged idling with hot turbos help.

Emissions System:

Early models can have issues with the Air Pump system and catalytic converters. The manual provides troubleshooting for these.

Vacuum Leaks:

Multiple vacuum hoses are present; leaks can cause rough running and performance issues. The manual details troubleshooting and replacement.

Ignition System:

Ignition coils and leading/trailing spark plugs require specific maintenance. Poor ignition performance significantly affects rotary engines.

📚 Vehicle History
