Robin did a video interview with Dankwart Eiermann CEO of Wankel Supertec at
Aero in Friedrichshaven. Dankwart is the only living technician that worked
with Felix Wankel directly as far as I know.

He stated Supertech redid the e/R eccentricity ratio to increase
the effective compression ratio to 14:1 and achieved a BSFC or fuel
burn reduction of 20% or .4 English BSFC or 240g/KwHr French BSFC.
This was direct injection on diesel fuel. He said it would burn
anything. The prototype engines are being made in Wisconsin
somewhere but he would not say by whom.

Rumor has it Wankel Supertec are having a bit of trouble getting the
injectors to work at the target of 6000 RPM. That of course will
affect the power to weight ratio. One rotor assembly is equivalent
to a one liter 2 cylinder four stroke piston engine. It is a modular
engine that can be stacked to four rotors. One rotor generates 65 HP
and weighs 70 Kg or 154 pounds. A four rotor would be 260 HP and weigh
130 Kg or 286 pounds.

There are three families of engines. .7 L, 1 L and 1.148 L
The largest 4 rotor would be 298 HP and would weigh 312 pounds.

I can hardly wait to get my hands on one.
