Mazda RX-9 Use Toyota Hybrid Drive?
Despite Previous Doubts, Mazda Bringing Diesels...
Petrol-electric hybrids are not environmentally sustainable because they still rely on fossil fuels, however carmakers are still pouring millions of dollars into improving the technology instead of focusing on better alternatives. There’s also the fact that many modern diesel vehicles and even some petrol compact cars achieve much better mileage figures than hybrid halo cars like the Prius.
Consumers are convinced that hybrids are the solution, researchers Jean-Jacques Chanaron and Julius Teske claim in their paper Hybrid Vehicles: A Temporary Step."There is a general convergence of strategies toward promoting hybrid vehicles as the mid-term solution to very low-emissions and high-mileage vehicles," the researchers say. "But a convergence is based more on customer perception triggered by very clever marketing and communications campaigns than on pure rational scientific arguments and may result in the need for any manufacturer operating in the U.S. to have a hybrid electric vehicle in its model range in order to survive."
Fortunately, there are carmakers out there pushing for alternatives. We’ve already seen Tesla’s all-electric roadster and next month Pininfarina will unveil a 700hp fuel-cell concept so there is some light at the end of the tunnel.

Personally, (and again, I'm an electrical engineer here people) Hybrids will extend our knowlege of batteries, which are likely to pay off more-so than hydrogen fuel cells. To me it all comes back to the whole hydrogen production process in the first place. you have to make hydrogen, and the only industrial scale process is to split water with electricity. and then you have to pump the hydrogen to stations across the nation? why dont we take that electricity, and send it through a WIRE... to my GARAGE... where i can CHARGE my car.
remember, fuel cells are just a fancy way of making electricity. you can only get as much electricity out of a hydrogen fuel cell as it took to split the water at the factory in the first place. why not send that electricity to my house? Battery technology is much cheaper and much more reliable than fuel cells are today, and that will likely be the case 10 years from now.
Battery technology keeps progressing and has the potential to become (in theory) much more WEIGHT EFFICIENT (which is what really matters here) than fuel cells. In theory, a fuel cell can only ever make as much electricity as what was used to split the water that your fuel cell car is now carrying.
Battery technology WILL be the standard. Trust me on this. Fuel cells are just a certain type of battery.

I don't think that hydrogen is a viable alternative either. Chris made some good points about the energy needed to split the water. But the task of an infrastructure is HUGE. We would need refineries, pipelines, train and truck tankers, and filling stations. That's like taking the whole gas industry and rebuilding it, and I've heard people say that it's not going to be hard to start using hydrogen, really !?!?!, because that sounds pretty hard and expensive to me. Gas cars will die off eventually and I dread the day but I will recognize that electric cars are the way of the future. Our society is already trying to produce clean energy with nuclear plants, water and wind power. Eventually making that electricity won't be AS bad as it is now and we already have an infrastructure to do so. Hydrogen is just hype, electricity is the future.

How are hybrids delaying fuel cells when there is no hydrogen highway, nor any interest amongst either consumers nor politicians to build one?
And, let's review hybrids versus clean diesel. First, hybrids are only just emerging and technologies like lithium and capacitors will make even gasoline hybrids much more fuel efficient and cleaner than diesel. Second, hybrid technology can make diesel vehicles much more fuel efficient as well. Third, what similar sized diesel achieves much better than 50 mpg in the worst stop and go traffic? That's right, there ISN"T ONE.
In the end, the upside potential of hybrids is huge, diesel is almost tapped out. Sure clean diesel can compete with hybrids today, but not tomorrow.
But, then again, 100+ mpg hybrids, such as those demonstrated by Hymotion or HybridsPlus, are such a waste of time, right? If we all just convert to diesel or wish the hydrogen highway into reality, the world will be funky-doory!
BTW - Part of the reason that Toyota developed the Hybrid Synergy Drive was so that it could begin mass-producing much of the electric drive components that its fuel cell vehicles will use. More evidence the Prius is killing fuel cell vehicles I suppose?

This report is stupid, No one is preventing anybody from researching or making a big leap into electric cars or any other. you don't even have to go to mass production but just have to fill in the gap and solve this consumer problems and nuclear power(war) or alternative (like what? ). Big decision here, your not helping but just using. LoL

And this is even funnier: "such as viable fuel-cell cars that can use sustainably sourced fuels, such as hydrogen." Last time I checked, there wasn't much hydrogen gas floating around (and even less that was sustainably made), nor any that was cheap. Sure, you can use solar cells to make hydrogen and then use it in a fuel cell. Nice but not efficient or cheap. Better to use that electricity and make an electric vehicle with it.
