Sad to see all development being stopped. Hate it when innovative products fail and we go back to the same stale stuff.

good riddance i say, the rx8 is the only car i have ever seen that could not be started up moved then shutdown without flooding the engine, which took me a good 30 minutes to un-flood oh and the starter loved it...

why do i have to let the thing warm up before shutting it down? oh and the apex seals start to break down and burn oil what a great engine..:thumbsdown:

As much as I like the Wankel for being different, it just wasn't ever really meant to last in today's world. The emissions were worse than Otto-cycle engines (even with all the improvements Mazda made with side ports and the like) and the fuel economy was much worse than Otto-cycle engines of comparable power. The Wankel's advantages of lighter weight and smaller physical size just can't outweigh the efficiency advantages of the Otto-cycle engine given the priorities necessary today.

It's still sad to see it go, but in its current forms it just didn't make sense in a modern mass production car and its days have been numbered for some time now.

Sorely misunderstood motor. Fortunately, those that don't like 'em just means more parts for me. :)

And to clarify...that does NOT mean more parts to fix what's broken as I actually take care of my car and the motor does NOT break at random. ;)

Kinda sucks they cant improve the fuel consumption.I was going to buy a rx7 with 80k miles with minor body damage about 5 years ago for $5900 but I never did.

It seems to me like inefficiency is inherent to the design of the engine. When burning air/fuel expands, it doesn't just push the rotor away... The rotor also has to slide sideways and rotate. I'm guessing that's not as good a method of extracting energy from combustion as a piston sliding down a cylinder.

Good riddance. Is a POS motor and the only reason Mazda kept it going is for marketing.

Click to expand...

Lack of valves, long combustion chamber, and very little leverage/torque angle operating on a rotor.

Mostly the long combustion chamber, that was it's real weakness. That's what caused flooding issues, that what caused the poor fuel economy. It is simply a terrible volume to try to burn.
