I once owned two RX-7’s, and I love the rotary!

Hey GS650!

According to the many PRESS RELEASES about the transmission design being used in many transit buses for quite a few years.

So Gm/Allison actully started with really HUGE vehicles and downsized the project for the Tahoe.

yeah check here for a pic I took of how large the tank is.. thing is, it has two fuel doors, a “gasoline” one and a “hydrogen” one.

a handful of other pics of the car there as well.

@orenwolf: the H2 tank replaces the 3rd row, doubt it will fit in your Mz3

At least they are not trying to make a 6000lb SUV into a hybrid grocery getter. maybe GM should start with small cars for hybrid experimental transmissions.

Apparently Suzuki will road-test a fuel-cell vehicle (based on the SX4) in Japan.

Probably because the Mazda5’s JDM name is better suited to the task. Or, more space for improvised computers, hydrogen tanks, etc. that have just been shoehorned in there.

I hope hydrogen works out. It’s our best long-term hope for the survival of the internal combustion engine if evidence ends up supporting anthropogenic global warming. If we end up going all-electric, it’ll be the end of shifting gears…

Why the Mazda5 though? I’d take one provided a) I could fuel it, and b) the system would fit inside my Mazda3 hatch.

I read somewhere that Mazda is supposed to build at least ten of these, making the FCX Clarity and fuel cell Equinox look like mass produced vehicles.

The Wankel is THE simplest ICE on the planet. So all this article is skewed. Fact is that there have been hydrogen Rotaries for over a decade in University test and studies. Hell, even backyard geniuses have them for fun.

Since it’s most like the most prevelent element other than carbon, it makes perfect sense to use this engine. However inefficient in gasoline form, it does have merit in hydrogen form.

Go Mazda!

From what I have read, the rotary engine is better suited to run on hydrogen than the conventional cylinder engine. The details escape me but the chambered rotary design helps prevent backfiring.
