The rotary engine is well known in the automotive community, both for reliability issues and for being amazing. So is the rotary engine really one of the coolest engines ever or is it a poor design that should be left behind?
WheelHouse answers all the questions about the automotive world you never thought to ask. Nolan Sykes looks at the history, sociology and psychology behind the cars you love, and the features you might overlook.

My buddy. Had a 1983 rx7. Green 5 speed and. It would fly .not god quick but yes the rpm and sound was great. The car was low as crap. I actually rode back in the hatch to school in high school. Glory days. Some cars just put a smile on my face really easy. Miss that old car.

I have a 2002 mazda protege lx with a wankel engine and it runs almost as good as the day I bought it and it has never burnt oil it runs so clean every time I go to get it smogged they compare it to a hydrogen engine. Mazda wants to buy it back they say its the only one still on the streets I love my car I am its one and only mechanic and its never blown or wore down any seals.

Mazda have done promising research on HCCI ignition for its SkyActiv-R rotary engine project using research from its SkyActive 2 program. They have removed the need to locate the spark plug outside the combustion chamber to allow the rotor to sweep past. Mazda solved this in the SkyActiv-R rotary project. Rotaries generally have high compression ratios giving the design easy adoption of homogeneous charge compression ignition (HCCI). It looks like the next Mazda rotary will not have a spark plug and be HCCI ignition. Fuel consumption will match piston engines and when used at a constant speed genny as in a hybrid, outperform piston engines with all the advantages of low weight, small size, super-smooth, simplicity, etc. The expectation will be that the engine will be introduced in 2020, the 100th anniversary of Mazda. Looking good. Rotaries are better suited to constant speed, high efficiency genset applications rather than direct drive via gearboxes. In that application piston engines cannot compete. Rotaries are better suited for series-hybrid cars being much superior than piston engines. Direct fuel injection and laser ignition will improve the Wankel considerably when introduced. The problem of unburnt fuel in the exhaust will be eliminated improving emissions and fuel consumption. The engine performs very, very well in fuel consumption and emissions running at a 'constant speed' turning a generator - its most efficient "sweet spot". Wankels lose efficiency dramatically when they are revved up and down as when directly driving a car. The engine has a vastly superior power-weight ratio than piston/crank engines and is about one third of the size and weight of a piston engine for a similar power output. All these positive attributes combine to make a superb range extender, when the wheels are turned by electric motors. If a car is plugged in each night and uses grid power to run most of the time, then wear on these units will be negligible. As the engine is only periodically used, the life of the engine is greatly extended. Also newer metallurgic techniques are being used to make the engines. Even when batteries are depleted, the Wankel can provide enough electricity to power the car and still be economical. It takes only 25 to 30hp to propel a large American car down the highway at 70mph. Yet they put engines in them that can output 150 to 200hp. Most of that output is for acceleration and heavy loads. Highly inefficient. The great thing about a series-hybrid is that the generating engine works totally independent of the demands of the electric driving motor, enabling maximum efficiency when running. This means the generating engines can be greatly downsized. The battery acts as an energy buffer to give acceleration boosts. Mazda announced a rotary in a hybrid will be available in 12-18 months.

It's a shame they didn't put the video from Mazzei Formula in here, this is one of the sickiest sounding rx7s I've ever seen

I wouldnt doubt tht Mazda will make another rotary car again. Or at least use another companies support to make it happen.

Mazda need to design a skyactiv rotary car. Id buy it immediately. the gas mileage on my 2011 rx8 is abysmal in the city. maybe 12 mpg or so.

you dont need to push in so much more money in the wankel /rx8 development, its just the potential owners are getting more unreliable and dumber and dumber every year, you just wait and see what they will do with the Rx9 . big rocket science to understand and make daily out of a wankel ... bunch of swap experts, they will put the Bmw supra crap in it before the warranty expires. If Mazda really wants to sell Wankel cars angro, should start first engineering some Skyactiv spaceship containers to deliver the cars to Kepler-452b , more chances there to find real driver/owners for them and not just 'holders'' on registration, on this planet ...dangerously out of stock ...

btw i own a 05 rx-8 and i thrash the shit outta of it and its still going strong after 162,000 kms

Suzuki built a rotary motorcycle, the RE5, but they didn't trust their mechanics to work on it. The repair procedure was to pull the engine, place it in a wooden crate, ship it to Japan, and await return. There is a small cult following for the bike online now, which is pretty cool.

Rx8? Might be a fun daily. It still looks good. Maintaining might be pricey but car payments are worse.

I bought my RX7 GS new in 1984. I still own it and drive it weekly. 174,000 miles on the original 12A rotary engine. Still running strong and passes smog. It's the ultimate anti-Tesla.

The rotary engine will never be viable as it can never meet modern emissions standards. If you like clean air (and who doesn't) a rotary is just no good.
