I interview Seiji Tashima, the engineering expert for Mazda's new
rotary, at Tokyo on your behalf.  Here are a few details he revealed:
rotor width reduced by 5mm  saves weight, improves apex seal  performance
trochoid is 25mm wider, 35mm taller  for more displacement and torque
would not reveal increase in eccentricity. New displacement is  800cc/rotor.

Aluminum end plates have plasma-sprayed wear surface direct and  indirect
fuel injection.

Torque gains come from longer e-dimension, more displacement, direct
injection.

Would not confirm 300 hp power goal.

All gas seals improved, smaller flame holes adjacent to spark plugs.

16x engine ran for the first time this year. full development will  be at
least 2 more years.

Engine weight is reduced from 125kg [275 pounds] to 100 kg [220  pounds].

I hope you find this useful.

We sure do Don, Thanks

Paul,
Your response to Don should have been, "Tanks, Sherman."

This is a reflection of a forty year rivalry :)
