The volume in the sealed part (where combustion takes place) is rather large, making for a low compression ratio. Also, the air and fuel don't have much room to mix in the combustion chamber, so you get worse emissions.

It is a good, simple, lightweight engine, but you need to rev it to insane levels to make decent power, which it happens to do quite well.
What a great animation, better than some I've seen!, hmmm, in the 50's, that's later than I thought, I was about 24 then, [I got married 2 years later] I used to collect mags on the Wankel, I even had a giant poster on the wall in my room, depicting an exploded diagram showing ever minute component down to very small bolts & retaining clips, have you seen one of these?
I know, I know a bit weird to act like that at that age, but my love of cars began much much earlier at age 7 or thereabouts!, since then it's been vrooom vrooooom all the way, yeah!!

Rotaries are awesome motors, they don't like turbo though, you'll blow an apex seal just like that.

Rotaries got a kind of bad name because of the Wankel rotaries, they weren't that good, but the new Renesis rotary that is in the RX-8 is supposed to be tons better.

Rotaries don't make much torque though, I think the rx-8 is something like 260 hp with like 180ft-lbs of torque. That means you have to keep it revved really high to get it to go anywhere.
