Mazda RX8 interesting facts
October 12, 2008 · Print This Article
The RX-8 is anything from an ordinary car. From the unique 1.3 litre Wankel rotary engine to the rear-opening passenger doors this car is truly a modern marvel. Below is a compiled list of some of the more interesting hidden-features embedded in each RX-8. These fun facts were borrowed from the knowledgable forum members here and at RX8Web.com

The RX-8 is anything from an ordinary car. From the unique 1.3 litre Wankel rotary engine to the rear-opening passenger doors this car is truly a modern marvel. Below is a compiled list of some of the more interesting hidden-features embedded in each RX-8. These fun facts were borrowed from the knowledgable forum members here and at RX8Web.com
- The RX-8 has an aluminum hood that incorporates Shock Cone technology to minimize head injuries in the event of an accident with a pedestrian
- The RX-8 power steering is electric instead of the old style hydraulic systems
- The RX-8 has a return-less fuel system. This means warm fuel isn’t returned to the tank and fuel evaporation is reduced.
- The RX-8 actually holds approximately 7 liters of oil, but when you change the oil only 4 liters are drained and replaced. This is because the oil cooler(s) are not drained when you drain the oil pan.
- The RX-8 has an electric power steering system. If your RX-8 engine stalls for whatever reason (i.e. run out of fuel) then the electric power steering continues to operate allowing you to steer safely to the side of the road.
- The electric power steering management is based, like the engine AFRs, on a programmed map that takes into consideration vehicle speed, steering input torque and engine speed.
- 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 bonet and rear doors of the RX-8 are aluminum. Additionally, they arent welded together but instead joined via friction.
- The combustion chamber is covered with a resin coating to improve the initial engine break-in.
- The Eccentric shaft has a bypass valve that opens when the oil is cold to allow cold oil to bypass the rotors and help reduce the engine warm-up period.
- RX8s already have the seat heater wiring in place in the center console, even if you dont have leather seats or seat heaters.
- The RX-8s fuel tanks contain two roll-over valves that close and stop your charcoal canister from being contaminated with fuel in the unlikely event of an RX-8 rollover.
- The glove compartment light is on all the time while your headlights are on.
- It is possible to disable the TCS/DSC completely on an RX-8 by pressing and holding the DSC switch until both indicator lights illuminate.
- Additonally, the dealership technicians can tell if youve set the DSC/TC to full off mode because doing it stores a fault code.
- The RENESIS rotary engine utilizes 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 RX-8 Tire Pressure Monitor System has both a low pressure and a high pressure setting.
- 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).
- The carbon fibre drive shaft is protected from damage by shields and the connector pipe of the exhaust system.
- A spare tyre is not supplied as standard.
- Not tightening your gas cap correctly after fueling will cause a CEL (Check Engine Light).
- Using the factory supplied tire sealant as a repair requires the replacement of the tyre.
- The RX-8 clutch pedal height is adjustable.
- There is an audible alert tone when your car reaches 8,500 RPMs.
- Chassis Dyno-ing an RX-8 will make the ABS/DSC system think it has a malfunction and give you a CEL. However, if you shut off the DCS and TCS you can dyno the car without causing a CEL or DTC.
- The RX-8s automatic headlight adjusters, for the HID equipped cars, sensor is on the REAR anti-roll bar, which is why a lot of folks complain about headlight aim after they install lowering springs.
- The catalytic converters contain Platinum and thats why theyre so expensive to replace.
- The steel exhaust systems grow in length by about an inch when they are up to temperature.
- It is possible to listen to sounds coming from each individual speaker of your car, in a prescribed order. With the radio on, Press the power button and AUTO-M at the same time for 1 s. The speakers will then sound in the following order: Front passenger side speaker and tweeter, drivers side Front speaker and tweeter, drivers side rear speaker, and finally passenger side rear speaker.
- The early RX-8s had black windscreen washer tanks, and later ones had opaque white so you can see contents without taking cap off.
- All the instrument cluster warning and indicator lights are LEDs.
- The 18″ (non-bright finish) OEM alloy wheels are painted and clear coated.
- The RX-8 has drive-by-wire. There is no accelerator cable. The accelerator pedal sensor is a dual sensor that outputs to the PCM dependant on pedal position. Each sensor is a backup to the other if one fails. The PCM outputs to the throttle body which also has dual sensors.
- The MAZDA RX-8 has a 5-Star roll over rating from the NHTSA. The RX-8 was the only auto in the US that got the 5-star rating.
- The rear brake rotors have 60 vents, while the front rotors have 54 vents. Additionally, the front disks are the largest ever offered on a MAZDA production car.
- The Power train Control Module (PCM) carries out a full sixty step test of the Metering Oil Pump (MOP) every twelfth time the engine is turned off.
- Zoom-Zoom-Zoom is from a 1994 soundtrack CD Only The Strong & was written by a guy named Kao Rossman, performed by Serapis Bey.
- The roof on the RX-8 has structural members that are constructed of nitride treated steel? Nitriding fuses titanium to the steel with nitrogen through heat. This produces a very strong, yet lighter weight (2.2 lbs less than ordinary steel) roof and contributes to better handling.
- The RX-8 employs mode control panels which are 2 circular depressions in the floor panels. These two circles vibrate alternately creating waves which cancel each other out and reduce noise and vibration in the cabin.
- At about 13,000rpm harmonic vibrations will destroy a RENESIS, but it could theoretically live its entire, long life just shy of that.
- There are four side seals in the RENESIS rotor. A keystone to scrape carbon buildup from exhaust gases, a cut-off seal to eliminate blow-by between intake and exhaust ports, and twin oil seals to well, you know, keep the oil where it needs to be.
- There is a Seat Track Position Sensor that tells the onboard airbag system what position your seat is in.
- There is also an airbag sensor in the front seatbelt buckles to tell the system that your seatbelt is unfastened.
- The 190 has larger secondary fuel injectors than the 230.
- The clock on the NAV system is nearly perfectly accurate thanks to GPS.
- The Automatic Level Controls for the radio incorporate a microphone that was tuned to listen to the sounds your car makes while ignoring sounds of other vehicles in order to automatically adjust volume appropriately.
- The boot lip spoiler is fitted in Europe for fuel economy reasons.
- As the rotors rotate the apex seals are actually sucked away from the rotor housing and therefore a spring is needed to keep the seals planted against the trochoid chamber walls.
- The rear differential doesnt use clutch disks like normal LSDs do? Instead it uses a complex series of gears to allow the wheels to rotate at slightly different speeds, but still lock under given conditions.
- The front wheel arch vents are not just for show, but do indeed help to vent hot air from the engine bay.
- The RX-8 employs a first ever multi-link rear suspension for a MAZDA production sports car.
- Each Renesis engine is hand-built (assembled) from start to finish by a single person.
- There’s a special compartment for coins to the right of the steering colum no need to use the ashtray!
- The slot in the driver’s sun visor is handy for car park tickets!
- The ‘virtual’ b-pillar in the rear door is a structurally sound as any saloon car
- The patches on the bumper of the 230 are the headlamp washer covers, and pop out about 7cm under wather pressure to reveal the nossels that spray the headlamps, to prevent the xenon beams from being scattered by dirt. They can be manually pulled out for cleaning.
- The RENESIS name stands for Rotary Engine Genesis But also for Rotary Engine for the New age with Exhaust on the Side and Intake on the Side.

Can anyone confirm this? I have to drive with the seat all the way up, so this is a big deal to me. Is it only for the powered seats, or does it work with the manual-adjust cloth seats as well?
