Not really, I'm thinking a small hybrid to provide a small amount of low end power as well as spinning fuel out of the engine when it's shut off cold. This would be seperate from the starter in sequence. This could also enable start/stop of the engine when sitting at a light to improve city driving MPG.

Competing with the Corvette may not be a good idea, but what about a low production, expensive, exotic, rotary "halo" car ala the Ford GT? They may take a hit on the car, but it would boost Mazda's brand recognition, bring people into the showrooms, and raise people's confidence in rotary engines.
p.s. it's my first post. hi forum..

And this response to your post is my 1000th. Cool.

actually thats the HIGHEST curb weight for the car in the 6speed with AC trim. the lowest being 2522 for the 5 speed no ac trim

Not to mention that a 50hp starter motor would be useful in deflooding an engine: a mild 500 rpm or so cranking speed for normal starts and an as-fast-as-possible-with-gradual-acceleration cranking speed for deflooding

It would be very clever IMHO. On a further level, the motor could be integrated in the flywheel and wired to act as an alternator as well. In this scenario three fairly heavy components (starter motor, alternator and flywheel) would be replaced by a single one.

I hear you! I am so torn between a potential M1 or 1M or what ever BMW decides to call it and the new rotary car. If Mazda did come through and produce a 2800 pound 16x rotary, I think that would win out. It would probally be less than the M1 also...

no... the radius is different. So the housing has to be bigger. Just that the rotor width is 70mm, according to their guessimate
Close to a smaller and thinner 21A

IMO the rotors would be 80mm like the 13B., but longer stroke (wider diameter) larger circumference.
BUT, Having said that, perhaps that is where reports of "larger but physically smaller" comes from, could be 75 mm.

Boy that is one "Long" looking side seal, I would imagine that they would be slightly heavier (thicker) as it has to seal a much larger surface area when compared to 10A,12A,13B.
Also stronger side seal springs.
I have some concerns about their long term reliability.

The rotor housings cannot be physically smaller, unless they have narrower coolant passages, which I don't think would be the case.
However a thinner front and back covers and better packaging will make it physically smaller.
