When Nissan, Honda and BMW start making rotaries, then we can compare HP/torque/MPG numbers. If Mazda wants to drop a V6 into the RX8 chassis and call it something else, then we can compare HP/torque/MPG numbers. The RX8 without the rotary is another "me too" car, not to mention it loses all the handling and weight advantages that make it so special. It's not my fault, yours, or Mazda's that so many people only buy based on numbers. Gains in piston technology are shared amongst manufacturers, so it stands to reason that over time power and efficiency gains can be made hand in hand. With Mazda and only Mazda working on rotaries, they can't borrow anyone else's notes, so advancements would expectedly come slower and be less incremental.
Taki supposely has the 7 speed dual clutch system... wonder if they will use that.
What's up with all these stupid brown's gas or HHO posts lately... if hydrogen add to gasoline will boost power and make it more cleaner, wouldn't the hydrogen RX-8 or even this RX-9 be injecting small amount of hydrogen with gasoline already????

Gas to us is LPG ( Liquid Petroleum Gas ), or can be Natural Gas..
I would think much of the world calls Gas, Petrol..... anyone care to survey that?

The hydrogen rotary Premacy van only makes 40% more power because they are also factoring the power from the electric motor in with that figure. The engine on it's own makes far less power. Hydrogen is never going to make as much power as gasoline. It can't.
Hydrogen is just a fancy feel good option for the greenies. No one is going to use it. Most people can't get it anyways. It's all about green marketing. The fact of the matter is that hydrogen isn't going to be a vialbe fuel until it's cheap and easy to make. Unfortunately it's neither and there's no end in sight to change that. By the time they figure that out, all cars will be 100% electric anyways as that's the future which would relegate hydrogen to be nothing more than a potential fuel used by a range extender engine in the few cars that will still need them.

Perhaps...
A recency survey here has 40% of participants "believe" Hydrogen was the fuel of the future when compared to other options listed.
The Premacy Hydrogen RE Hybrid is a concept car in which a hydrogen rotary engine with dualfuel (hydrogen and gasoline) capability is combined with a hybrid system. The hydrogen rotary engine and the motor are incorporated into a power unit that is transversely mounted at the front of the car in an FF layout. The high-voltage battery is located under the second-row seats, and a high-capacity hydrogen tank is located in the space that would otherwise be occupied by a thirdrow seat. Efficient packaging permits ample interior space together with the superior environmental performance of the hydrogen rotary engine and hybrid system.
The Premacy Hydrogen RE Hybrid's key technologies...
- Transverse-mounted hydrogen rotary engine in FF layout
By redesigning an existing hydrogen rotary engine to suit an FF layout, Mazda greatly expanded the range of models in which hydrogen rotary engines can potentially be used.
- Dual-fuel system
For the driver's convenience, the hydrogen rotary engine has the dual-fuel system that is also used in the RX-8 Hydrogen RE.
- Hybrid system
The hybrid system normally stops the engine to save fuel when the vehicle is stationary (at traffic lights, for example) then automatically restarts the engine using the motor when the driver is ready to pull away. During acceleration, the motor supplements the engine's torque for superior response. During deceleration, the motor operates as a generator, recovering braking energy and using it to charge the battery.
So similar to a Prius, but Mazda has Dual Fuel.
RG do you know of any other make that has a duel fuel electric hybrid?

Problem is that hydrogen is highly reactive and does not exist terrestrially in a pure, elemental form. Separating hydrogen from the other elements it is often bonded to (example: water) creates a net energy loss.

I somehow doubt it..this is just media speculation.
Mazda Japan president was recently in Australia, he said any alternative fueled car will not be seen before 2015.
I take that as Hydro, or any hybrid.

Oh brother, another manufacturer going the "Me too" route.
The future isn't ethanol, or burning hydrogen, that's just "Too scared to leave our tried and true, and really grab onto the future".
The near future, we'll have more junk, "half this solution and half this solution", cars. I'm sick of all this hybrid junk!
What is the future? Electric. Most likely powered by a Hydrogen sponge tank and a Ballard energy membrane. None of this Lithium battery (old technology: yawn) nonsense...
Common Mazda lead a little!
Zoom Zoom is not "Rotary Engine" ONLY.
Try making a car that has four electric motors, one in each wheel. That would be positively Bad@SS!
Look at the Tesla Roadster, they are using OLD technology, and a single electric motor. They are leading the way with mediocre advancements in thinking.
How long are we going to suffer under the direction of Hybrid tries of success?

^ the response time of all electric is astonishing.. Tesla Roadster had an episode on in 'future cars' (that you mentioned). instant response on instant requests... pure sickness. 13k redline, 4 sec 0-60, 250mpc (miles per charge) at around $5.00 a charge. problem is, it took over 6800 lithium ion batteries to achieve this result. problems are as battery dies, so does overall performance, just one of many downfalls...

Since the fact checker can't even get that right (Mazda has been experimenting with Hydrogen powered rotaries since the early 90s AND producing road driven Hydrogen powered vehicles for the last 2 years), I expect everything else in the article to be just as made up.

A qualification.. it has been the past 2 years (give or take a few months) that the Rotary Hydro engines have been in production (rather than my bad word of experimenting) for lease in Japan...ie in numbers far greater than experimental and or prototypes of the late 80's and 90's.
One would imagine that the small numbers of RX-8's leased to the Japaneses Ministry Departments are still in 'experimental and evaluation mode" for future mass production and ironing out the bugs so to speak.

Gee astounding observation..

See I was commenting on the writer's fact checker, not your's.
But there are Hydrogen 5's running around in LA, so I would hardly say that is in experimental or eval mode... More that the infrastructure is not yet available for supporting mass production (Vs the limited production Hydrogen RE powered 5's/Premacys and RX-8). I believe my county (Sonoma) is also looking at picking up a bunch of RE Hydrogen 5's as well for county workers.

they talked clearly : Mazda SELLS 30 rx-8 HRE to norwegian procjet Hynor....
those cars runs together ordinary traffic and respect Norwegian Road Laws (sorry for my english)
rx-8 HRE IMHO is not a prototype but a limited (small) production veichle
