10 Totally Random But Fascinating Facts About The Mazda RX-8

• The headlamp dipped beam pattern on both the 192 & 231 has a specific beam of light above the main cut-off that is there to illuminate overhead reflective road signs. This pattern can be seen as a straight line if you drive up close to a vertical wall.
• The RX-8 steering wheel has a magnesium core to save weight.
• The front seatbelts can be buckled into the rear seatbelt clasp but cannot be unclasped. DO NOT DO THIS!
• The RENESIS rotary engine utilises a metered oil pump to inject a small amount of oil onto the apex seals of each rotor to keep them lubricated and reduce failure.
• The high frequency sound you hear under the hood when the key is on but the engine is off is the electric throttle actuator pushing the throttle butterfly toward closed, waiting for you to start the engine.
• Every time you first start driving the RX-8 there is an audible thump heard from the car. That is the ABS braking system performing a self-test.
• The manual RX-8 models have a carbon fibre drive shaft (the non-UK auto has a steel drive shaft).
• There is a Seat Track Position Sensor that tells the onboard airbag system what position your seat is in.
• The BOSE sound system is tuned differently for a Mazda RX-8 with leather upholstery as opposed to one equipped with a cloth trim
• The 190 has larger secondary fuel injectors than the 230.
