It amazes you that people want the looks of a mazda sports car but with a reliable engine that has room for serious HP gains?
I love the rotary but it doesn't amaze me that people want both power and reliability.

I mostly just shake my head in amazement at people that expect Mazda to produce a production car with a p/w ratio far far higher than anything they have done before, squeezing every last drop of power out of an engine that has a worldwide reputation for poor reliability.
Even if they somehow pulled a miracle out and actually did ... no one asking for it in this thread would be able to afford to buy it. So they still wouldn't have what they asked for.
11-13 lbs per horsepower is where Mazda has historically landed again and again and again.
Given the ND's weight of 2,300lbs, Mazda previously mentioning a scalable platform, the chances of a coupe being at least slightly stretched ... a weight gain of 10-20% is reasonable, putting it in the 2,500-2,700lb range.
That would suggest a peak p/w of about 192hp at the lowest (2,500lbs, 13lbs/hp), 245hp on the high end (2,700lbs, 11lbs/hp). 220ish being the middle, and pretty reasonable. It would also have substantially more torque overall, especially low end torque, due to the presumed 16x dimensions of a longer stroke, plus a simplier intake that would likely be tuned for a lower range band, the higher compression SkyActive technology, etc...
It's also amazing that Motoring still has any level of credibility in the rest of the automotive journalist world. Even the loudest braggart with the worst luck will eventually roll double sixes.

Maybe Mazda execs are looking at Bentley and thinking "Sheeeeeeeit, heavy metal is where it's at, yo! 5000 lb or suck it, beeotch!"
That would keep the p/w of the super-'lectric-twin-capacitative-turbo-blow-hard-rotary-charged-Wankel supercar at 11...

It's based on whatever scale you want 
Lockheed uses lbs of thrust to tons
It could be tons of TnT to grams ...
I'm not using whp in those numbers because when talking about the manufacturing level, they always use at the crank.
The whp p/w numbers would be corresponding lower.

I can totally see Mazda detuning the next rotary for reliability and cost, which inherently means that the aftermarket can then re-tune that back up. I don't think Mazda will make the next rotary run on the ragged edge from the showroom floor. Too much to lose for virtually no gain other than some orgasms on magazine pages.

I guess this car will be above 300 HP 
Our RX-8's are 231hp with 1.3 MSP Engine
If they are going to use 16X engine it may be easily get 250-300 hp with N/A with FI 300-350 hp easily for reliable and fuel save limited powers.
When you will look BMW i8 1.5l engine car produces 362 hp. Electric motors produces 96 Kw equals 128 hp and 250 nm
MAZDA Brand New Rotary Engine for range extender 2013
330cc single rotor
22kW/4500rpm
Compression ratio 10.0
Intake Port : peripheral port
Exhaust Port : Single side port
Test with Demio RE range extender by Rotary Engine.
I am sure they will put these little rotary range extender engines to the next RX's for start stop technology, fuel saving and for emissions maybe at low rpm's this engine will work for fuel consumption.
That concept cars design language will give tips to us long nose short back weight distribution needed. If they use aluminium block 16X with turbos back of the car will not give perfect driving feels so that tiny range extender units with lithium ion batteriers equalize the distribution. All of us know that this car will be RWD not AWD GTR 35's weight distribution is 53/47 and its AWD.
I am sure that concept design will be hybrid rotary car. Hope will be.
