Car Forum / Hyundai Cars / May 2004Hybrid cars
Although I was interested in the newer hybrid models and anxious for Hyundai to show one, I recently found info that makes me think the hybrids are over rated. It seems that the US government standard test analyzes the emissions from a particular car ad engine to estimate the fuel economy. Wit Hybrids they still use the same test thus the ratings are higher than the car actually can and will produce. Government says expect 75 % of what the rating is, and Consumer reprots says expect 60% and 75% if you are doing everything just right! So those folks with the 53 mpg honda civics can expect 38 mpg or so. Great testing by the feds. Admit it is flawed but won't come up with a better system until 20 million is invested in research on the problem. Heck, why not put a full tank in the dar and drive it for 300 miles an then fill it again to see the mileage you got? There is a right way to do testing, and ther is a wrong way to do testing... then there is the government way! I'm more anxious to see more diesel engine vehicles in North America. I would love to see a diesel Santa Fe with the nice little hood scoop that the European model has. Diesel cars here in NA is not a huge stretch since most of the models sold here with gas engines are sold everywhere else in Europe with diesel engine. > Although I was interested in the newer hybrid models and anxious for Hyundai > to show one, I recently found info that makes me think the hybrids are over [quoted text clipped - 15 lines] > There is a right way to do testing, and ther is a wrong way to do testing... > then there is the government way! > I'm more anxious to see more diesel engine vehicles in North America.

Due to gasoline prices in my country the Santa Fe diesel engines are predominant (90 %). Actually there are only 2 engines avail, the 125 CV 2.0 turbo diesel or the 2.7L V6. Automatic transmission is almost inexistent. Diesel is more claimed to be more polluting but on the other hand the mileage is much better so I don't know what is better regarding environment. > Diesel cars here in NA is not a huge stretch since most > of the models sold here with gas engines are sold everywhere else in Europe [quoted text clipped - 24 lines] > testing... > > then there is the government way! >Although I was interested in the newer hybrid models and anxious for Hyundai >to show one, I recently found info that makes me think the hybrids are over >rated. Hyundai will be selling (for fleet use) fuel cell powered Tucsons this fall. >>Although I was interested in the newer hybrid models and anxious for Hyundai >>to show one, I recently found info that makes me think the hybrids are over >>rated. > > Hyundai will be selling (for fleet use) fuel cell powered Tucsons this > fall. That's where the future lies. Hybrids are simply a stop-gap, intermediate step until fuel cell technology matures and the infrastructure in put in place. Once that happens, we'll finally be able to tell OPEC to take their oil and stick it where the sun don't shine! > That's where the future lies.

Really? Where will the energy needed to make the fuel cells come from? They use hydrogen...which takes OIL to make, since hydrogen is not a fuel source, it's an energy transfer medium. What about the infrastructure needed to store and transport the hydrogen, which is very very, VERY bulky? I won't even mention the heavy metals pollution from millions of dead fuel cells. In the meantime, oil reclamation, recycling and biomass conversion is making leaps and bounds progress, so much so that we may not EVER really need hydrogen at all. In any case, don't hold your breath waiting for real-world fuel cell cars, like fusion, it's only a year or so away!! Oh, and flying cars come out in September! Along with the personal robot slaves to do all your work for you! :) Xin >>That's where the future lies.

The fuel cells that are most likely to make it into production are powered by ethanol or hydrogen peroxide, neither of which come from oil. There are also cells that use propane and LNG, which are available from domestic sources. > What about the > infrastructure needed to store and transport the hydrogen, which is > very very, VERY bulky? Not in liquified form, it's not. Besides, it's not necessary > I won't even mention the heavy metals > pollution from millions of dead fuel cells. What heavy metals? We're talking about fuel cells, not batteries. Hybrids are the ones with all the heavy metals in them. > In the meantime, oil > reclamation, recycling and biomass conversion is making leaps and > bounds progress, so much so that we may not EVER really need hydrogen > at all. Really? Exactly what "leaps and bounds" are you talking about? You cannot reclaim burned gasoline or diesel fuel, which accounts for the overwhelming bulk of oil consumption in vehicles. At 30 mpg, a car will burn between 100 and 250 gallons of non-reclaimable gasoline between each one gallon reclaimable oil change, depending on the change interval. At lower mpg, the ratio is even higher. In older cars that consume oil due to engine wear, there is even oil to reclaim. > In any case, don't hold your breath waiting for real-world > fuel cell cars, like fusion, it's only a year or so away!! Oh, and > flying cars come out in September! Along with the personal robot > slaves to do all your work for you! :) Your attempts at hyperbole don't change the fact that there are fuel cell powered cars on the road today and development is ongoing worldwide. If you want to talk about leaps and bounds, fuel cell technology is a good one to look at. A system that filled the back of a small van a few years ago now fits under the body of a compact car and produces more power. The technology exists and the infrastructure can be built. I'll bet that within five years fuel cell filling stations will outnumber bio-diesel stations in the US, though admittedly that's not saying much. Don't get me wrong, I'm not criticiziong hybrids. I'm just pointing out that they're probably a short term product. They're not being produced in sufficient quantities to meet the demand and the prices are so high that you can't recoup the increased cost of the car in fuel savings. I suspect that this is because the car companies know that this is not a long term solution. > >>That's where the future lies.

A quick search on google turns up article after article on hydrogen fuel cell cars, not one mention of any other type. Why bother to make ethanol when you can just as easily make oil from the same stuff? Hydrogen peroxide? How much is that a gallon? Last time I looked, no one was pumping it from the ground, which means it's not a fuel source. > > What about the > > infrastructure needed to store and transport the hydrogen, which is > > very very, VERY bulky? > > Not in liquified form, it's not. Besides, it's not necessary. Agreed, not needed. :) Liqiod hydrogen?

I am refering to the real-world conversion of any biomass, landfill trash, turkey gizzards, old tires, plastic, paper, etc., into oil. The process pays for itself, and plants are being built as we speak. Estimates are 30% of current oil usage (US) can be supplied turning trash back into oil. We can actually eat landfills up at one end, truck away oil at the other. > > In any case, don't hold your breath waiting for real-world > > fuel cell cars, like fusion, it's only a year or so away!!

I bet against it. :) I'm betting on working fusion in the next 1000 years, though. > Don't get me wrong, I'm not criticiziong hybrids.

You need to learn to search more effectively. Try going to www.howstuffworks.com and reading their section on fuel cells, for starters. > Why bother to make > ethanol when you can just as easily make oil from the same stuff? > Hydrogen peroxide? How much is that a gallon? Last time I looked, no > one was pumping it from the ground, which means it's not a fuel > source. You're not making any sense. Ethanol is produced from biomass, specifically corn. Why does something have to be pumped from the ground to be a fuel? Wood isn't pumped from the ground, but it's certainly a fuel source. Not that I'm suggesting wood burning cars. >>>What about the >>>infrastructure needed to store and transport the hydrogen, which is [quoted text clipped - 4 lines] > Agreed, not needed. :) Liqiod hydrogen?

Both can be used to power fuel cells. >>>I won't even mention the heavy metals >>>pollution from millions of dead fuel cells.

I wonder how much they use compared to the amount in the catalytic converters they'll be replacing. My car has two of them and they're not exactly light weight. >>>In the meantime, oil >>>reclamation, recycling and biomass conversion is making leaps and [quoted text clipped - 16 lines] > can be supplied turning trash back into oil.

I also don't see any bio-diesel hybrids on the market, do you? >>>In any case, don't hold your breath waiting for real-world >>>fuel cell cars, like fusion, it's only a year or so away!!
