What planet have you been living on since 1970? Wankels are now
extremely reliable: better than pistons. (the apex seal problem had a
simple solution) and Mazda and other manufacturers use side porting to
cut oil consumption down to very low levels.

If you'd ever driven an RX-8 or Rx-7 you wouldn't complain about
torgue.

Mind you the original wankel as planed by Dr Felix should have been
reliable as the whole outer engine and rotor were both to rotate so
that no seals movement should have occured at all.

Turbines so far have only been made of expensive materials whose cost
can not be reduced and even then struggle to be efficient at part
loads.
