I love me a good Rotary. They sound like a 2 stroke at idle, and like an F1 car at full pelt.
Unfortunately, you have to love your car, and know what you're doing to own one. Being plagued by very poor fuel economy and reliability, unless meticulously cared for and kept on top of. They could be some of the most fun you will ever have in a car, or one of the worst ownership experiences, its all in the details.
Spend time finding the RIGHT one, and look after it like your firstborn child thereafter. Here, Engineering Explained, a very informative automotive youtube channel, explains why the Rotary is no longer being produced.
4 Reasons Why The Rotary Engine Is Dead. The Wankel engine was last seen in a production car in the Mazda RX-8, and currently there are no rotary engines in production. Mazda may bring it back in the RX Vision, however there are many disadvantages to the rotary engine which has kept it from being successful. Rotary engines have a low thermal efficiency as a result of a long combustion chamber and unburnt fuel making it to the exhaust. They also have problems with rotor sealing as a result of uneven temperatures in the combustion chamber since combustion only occurs in one portion of the engine. Oil consumption is also a problem, as oil is injected to add lubrication and help keep the rotor sealed. Finally, emissions are poor and fuel economy is terrible, and ultimately this is the cause of it’s death.
