no- but they couldnt build more anyway. they have trouble increasing production to get more 3s out the door.
i was saying that the success of one product cant be measured by the sales numbers alone - you have to measure the success over the size of the company. for instance the rx-7 was clearly a success for mazda even though its total sales were less than the 350z 3 year production.

Not necessarily so. It depends on the battery design, materials, and technology. See the video:

I do believe A123 is working with one, if not more, of the manufacturers for a LiFe hybrid though... I want to say Ford but it's been awhile.

I'm just speaking from my own, highly limited knowledge.
I've used Li-ion and Li-Po batteries in some of my projects (R/C planes, helicopters and some of my robotic stuff) and when they go, it is pretty spectacular.
I watched a 12v pack weld an aluminum hard-case completely into a molten puddle once. It was awesome (excepting the $1k in damage it did to the custom electronics inside).

BSFC of 0.42 have been obtained and documented in stratified charge unthrottled direct injected turbo rotary engines. There's your fuel efficiency, with the turbo there's the power. With less fuel, emissions are easier to control, less catalytic converters are needed.

We had a competitors car catch fire from a little bit of wet oil on his exhaust heat wrap last year - by the time they stopped and got out to see what the smoke was, the entire rear clamshell had gone up, within 10-15s, the cab was alight, another 30s and the whole car was a bonfire - even with every fire extinguisher on site applied by everyone there ( 168 x 2L/3L handhelds ), we still couldn't stop the fire from melting the frame and engine block...

Getting back sort of on track..
Interesting side bit On 'Maeda San', the Chief Designer now at Mazda and Designer of our RX-8 and Mazda 2, on his BIO it asks what is Your Favorite Movie...YOu Will never guess..."CARS" ..Seriously..
Now we know where some of the Happy Faces come from!!

After reading about an alleged development in the 16X program using diesel fuel, I am wondering if Mazda isn't giving thought to a spark-ignited, direct injected, diesel fuel version where they can use the additional BTU content per volume to achieve a higher MPG figure. The general assumption that if diesel fuel is used, that the engine has to be compression ignited isn't at all true. Even the SAE published a paper years ago about getting a direct injected spark ignited wankel working. The questions I have, assuming such allegations are true, are what AFR will be ignitable and would the engine be multi-fuel capable or strictly diesel fuel?

Engines are multifuel capable, I don´t know why you are interested in AFR - since these engines are un-throttled, engines load is changed by amount of fuel, so AFR will vary greatly. At low load, it can be 45:1, at full power it will be approaching stoich ratio.

You know about these SAE papers, yet you didn´t take that little time to find them? I personally have 12 papers about direct injection, stratified charge RE
All of them has been found on internet.... magical, isn´t it?

I would like to see it be a "let down"; no new sports car; only a new set of engine choices for the RX8.

What a bunch of whiners.
Mileage is not that important. Mankind is clever, and will ultimately convert some other form of energy into transportation fuel.
Think more along the lines of nitromethane. Now there's a fuel![Wink](https://www.rx8club.com/images/smilies/wink.gif)
As for cost, we get richer every year, whats a couple thousand for a fillup.

mmm
On a side note, the rotary has always been the flagship/representative of Mazda.
To my knowledge Mazda makes its profits almost entirely on its 3-6 and even 2 ranges now days.
If the release of a new rotary was to occur, it will only be there to remain as a symbol of mazda's heritage.
You see some cars such as the Bugatti & the new Lexus LFA, These are just flagship model cars where the manufacturers show of their manufacturing/engineering abilities.
In the recent episode of Top Gear, even with the LFA's hefty price tag, Toyota actually makes a loss on the actual vehicle.
So if another Rotary comes, it will simply remain as a heritage and a option for enthuastics, i doult mazda will rely on the sale of this particular model to gain its profit.

Yup, soon we will be as rich as pre- WW2 Germany or modern Zimbabwe!

Don't you think you should give the car companies a chance to make a fun electric car before you **** all over it? Tesla's experience making electric sport coupes is that a single gear ratio isn't practical anyway, so I wouldn't be surprised to see electrics with gearboxes eventually. And besides, even if it doesn't have a clutch pedal, you still have all the other stuff you have to worry about if you're going to push the car to the limits of its traction.

The biggest thing is going to be not using a single energy source -- diversity is critical to survival, not least because diversity means no single resource gets depleted faster than it can be regenerated. The big problem with burning gasoline is WE ALL burn gasoline. We need a bunch of fuels and alternate energy sources to keep from overburdening any one segment of the ecosystem with the waste of several billion people.
