Audi Wankel

[NIck Miller]

Wankel's are inefficient just like pushrod motors are outdated and "old
techology."  Right, Mr. C6-z06 Vette?

Rotary's were pretty bad in the 70's during mazda's wankel Hey-day, but the
Rx-8 is not terribly bad for what it is, and you do find rotary's in a lot
of applications (like generators) outside of the automotive industry.  They
are a small segment of every market they are in, but they have continued to
develop just like every other sort of internal combustion engine has through
the years.  Supposedly the newest rotary, going from 1.3l to 2.0l, will have
even better charecteristics because one of the issues was drag/size of the
motor, and supposedly this will help a lot with efficiency in the newest
rendition.   This concept can be compared to "stroking" a motor, where you
get too much drag on the piston up and down the sidwall, lowering its rpm
limit.  Same idea behind F1 motors having big pistons + small stroke = lots
or rpms...

Either way its a cool concept.
