First, the torque issue, rotarys do have torque and bogs of it. If you know anyhting at all about rotarys you'd know how a rotary makes more power than a piston engine at the same engine speed... hmmm engine speed x torque = horsepower. Work it out. They make much more torque than a piston engine, about twice, and can make very long flat torque curves a wide wide rev range. The RX-8 is 1300cc and makes 220Nm, about the same as a ford 2.5 V6. Second myth, lack of bottom end torque. The RX-8 revs to 10000rpm, yet according to the mazda website it makes over 180Nm of torque from as low as 2000rpm to over 9000rpm. It does this without the kind of camshaft switching a s2000 might use to do the same thing. Not just the RX-8 but older rotarys are good at that too. the s6 Rx-7 has 255 of 300Nm torque available from under 2000rpm. Reliablity. With a fraction of the moving parts of a piston engine its a no brainer. Modern rotarys are being used more and more in aircraft because of sheer longevity. Emissions Moller's sky car is going to be using super reliable rotary engines that produce about 4% the emissions of a piston engine. Good design is all that was lacking in the rotarys 20-30 years ago Mazda site also says they will be doing a special 380hp triple rotor RX-8. Don't get my wrong i drive a piston powered GTR and love it but you gotta have some respect for the superiority of the wankel.
