Crash Test Information:
While formal NHTSA/IIHS ratings for early models are limited, the RX-7's lightweight, sports-focused design means emphasis was on chassis rigidity and driver control rather than extreme impact absorption compared to modern vehicles.
Active Safety Features:
Four-wheel disc brakes (standard across most trims), limited-slip differential (optional/performance trims), sport-tuned suspension, power-assisted steering

Available on later FC models and standard on many FD models, aiding in maintaining grip under acceleration.
Cruise Control:
Available on most models, particularly higher trims.
Original Connectivity:
Limited to basic audio and HVAC controls. No modern Bluetooth or smartphone integration from the factory.
Oil Change Interval:
Every 3,000-5,000 miles (depending on driving conditions and oil type). Rotary engines are sensitive to oil quality and levels.
Spark Plug Replacement:
Varies by plug type, but typically 15,000-30,000 miles. Rotary engines use two spark plugs per rotor.
Coolant Flush:
Every 2 years or 30,000 miles. Maintaining proper coolant level and condition is critical for rotary engine thermal management.
Timing Belt Replacement:
N/A - Rotary engines do not have a timing belt; they use a chain or direct drive for the eccentric shaft.

Brake Fluid Type:
DOT 3 or DOT 4, depending on model year and ABS system requirements.
Rotary Engine Wear:
Apex seal wear, rotor housing scoring, and vacuum leaks are common wear-related issues that can lead to compression loss and engine failure if not addressed.
Oil Seal Failure:
Oil seals (corner seals, side seals, apex seals) can degrade over time, leading to oil consumption and potential engine damage.
Ignition System:
Dual ignition systems can be complex; spark plug fouling, coil pack failure, and distributor issues can occur.
Turbocharger System Fc Fd:
Turbocharger seals, wastegate issues, and intercooler leaks can affect performance and longevity in turbocharged models.
Fuel System Emissions Controls:
Carbon buildup in the intake ports, EGI sensor issues, and catalytic converter clogging can impact drivability and emissions.
Mazda Rotary Legacy:
The RX-7 is intrinsically linked to Mazda's pioneering work and commitment to the Wankel rotary engine, a technology few other manufacturers have successfully commercialized on a large scale.
