    One big point being missed here... Hybrid can be gasoline-electric OR diesel-electric. Case Closed.
  • nippononlynippononly Member Posts: 12,555
    seems to have made the crucial point...there are many low-speed propulsion situations where it is simply not necessary to burn a fossil fuel - that is where the hybrid comes in - the electric motor can power the car around at low speeds, and shut everything down when the car is stopped or coasting.

    Of course, hybrids have little advantage on the highway, where they have the same mileage as their gas-only counterparts would have with a comparably sized engine, because the batteries become depleted and the electric motor can't help.

    This is where the diesel would be so helpful, because its fuel economy can ROCK on the highway. So clearly once they get all this sulfur content nastiness out of the diesel fuel, diesel-electric hybrids are the way to go.

    At least until the widespread development of fuel cells - I bet this is at least 25 years away from widespread availability at a comparable price.

    The batteries DON'T become depleted on the highway! That's a misconception!!!

    When cruising on the highway, the engine alone has more than enough power available to propel a Prius. So what you see 100% (yes, 100 percent!) of the time is electricity creation. Most of it is routed to the battery-pack for recharging. Some of the time it is consumed immediately by the propulsion-motor.

    I beg to differ, simply because whenever I do all-highway drives in our prius, I never get more than 40 mpg or so. That is about what I think I could reasonably expect from a 2900 pound car with a small 75 hp engine.

    Not to mention I watch the display, which is always feeding the wheels from the gas motor...sometimes the electric wil help but then for every five minutes there is of that, there is also five minutes of recharging the battery pack, which presumably is a bigger drain on the gas engine than just pushing the car would be. It all balances out - net zero after the first ten minutes on the highway.

    But I have topped 50 mpg if all my driving is on a city route! that is fun.

    is that I have very little problem with some hybrids as city cars. City cars however should not be as expensive as the hybrids tend to be in my opinion. Diesels at least get reasonable fuel mileage in the city and can do quite well on the highway. If they can run on Biodiesel then they do offer the solution so many have advocated. Clean burn renewable fuel. We have several owners of the new hybrids that have more than one car so they don't have as big a problem as someone like myself would have thinking of a hybrid as a replacement for one of my present vehicles. Admittedly I do not spend much time in city driving and I do live in the mountains so I get to drive a winding twisting road both to work and home. The drive home is 16 miles and a 3500 foot climb and so far TDIs seem to climb that grade a whole lot better than hybrids. To date neither hybrids nor Diesels have captured many peoples hearts but I could see diesels winning in the long run. The article on Biodiesel was more than interesting and if true does seem like a better solution in the long run.

    But...currently, given the availability of hybrids in the automotive market...it's gas-electric.

    More on diesel maintenance...
    10k miles oil change (using synthetic oil)
    20k fuel filter change (the expensive part)
    80k timing belt change (2002 TDI...the labor intensive part).

    That's about it for TDI routine maintenance.

    Gasoline-Hybrid:
    7.5k miles (probably less for real owners)...most likely using conventional oil...depending on the owner

    100k: Tuneup....using Platinum or Iridium plugs. Denso or NGK plugs aren't cheap either...Denso double platinums retail for about $10-$14, Iridiums are more. The Insight uses indexed plugs...each cylinder has a different spark plug part number.

    60k: fuel filter change. Though not suggested by Toyota or Honda...they claim it's a lifetime filter...they clog eventually and will cause driveability issues (been there before)
  • vocusvocus Member Posts: 7,777
    Being a 2-TDI owner (if I remember correctly), would you change to hybrid next time? Please explain your answer.
  • vocusvocus Member Posts: 7,777
    A good city car is the Metro/Aspire/Swift, consistently getting 40+mpg (even if they didn't have any power!), and being able to zip through traffic. Couriers still use these cars today, and some swear by them. They were also cheap to maintain, and seem to last forever without much problems. Yet everyone wanted a big, 8 million pound SUV that gets 2mpg, so these cars lost popularity. I would have one of these cars before paying so much for the technology of a hybrid to get about the same mileage from it.
  • john1701ajohn1701a Member Posts: 1,897
    >> net zero after the first ten minutes on the highway

    But the second you leave the highway you see an immediate benefit... because you spent the entire time on the highway topping-off the battery. So there is a net gain OVERALL when you take into the account the fact that you eventually have to get off the highway. Then later, you have to accelerate to get back on.

    Plus, your emissions on the highway would still much cleaner than just about everyone else's.

    Also, how fast do you drive? Cruising at 70 MPH I very routinely get around 45 MPG with Non-LRR tires and E10 in the tank.

    do not "clog eventually" in my experience - I believe Toyota when they say it is a lifetime filter. I have had numerous Toyotas over 200K for which I have had the entire repair and maintenance records, and nary a fuel filter replacement among them! My old celica I sold at 250K had its original filter - drove fine, no hesitation or hard starts.

    John - I mostly drive the limit, which is 65 here...sometimes I might stray a couple of mph over, but not much. This is a county car, so I do not look closely at what tires they put on it.

    Metro/Aspire/Swift were all really efficient cars, but they were also very basic, cheap commuter cars. If they had the sound-deadening materials the Prius has, for instance, so that it was not 100 decibels inside at 60 mph, they would not have been so efficient - more weight. If they had the smog controls that enables today's cars to be SULEV-rated, they would not be so efficient. The Prius and the Honda HCH are the next generation response to these cars - much lower emissions, comparable fuel economy, in a package that has the refinement of today's $20K midsize cars, with things like quiet interiors and auto climate control.

    I would be intrigued to see an experiment where they attempted to engineer one of those older models to have the interior sound and comfort levels and the emissions rating of the Prius/HCH - what I would want to know is (a) if they could meet that design goal in one of those older vehicles and (b) what fuel economy rating it would have then, as well as what performance rating (acceleration), since performance has been an oft-discussed topic on the hybrid threads.

    Before Bush trashed the program, the PNGV (Partnership for the Next Generation of Vehicles) program had Chrystler demonstrating a production-level diesel-electric hybrid based on a Dodge Stratus platform (a fairly large vehicle) that got near 90MPG.

    To quote MIT: HYBRID DIESEL WILL OUTPERFORM FUEL CELLS

    Meanwhile, a study performed by the Massachusetts Institute of Technology finds that fuel-cell cars, while promising in principle, will be out-greened by hybrid vehicles, particularly diesel hybrids, until at least the year 2020. The problem, the MIT study says, is how hydrogen fuel for fuel cells is harvested; until 2020, most hydrogen will be extracted from natural gas, consuming vast amounts of energy that will reduce their overall environmental benefit. In the distant future, scientists expect hydrogen to be "cracked" from water molecules through other power sources. President Bush has pledged $1.2 billion for the development of fuel cells, and many car companies are promising mass-production fuel-cell vehicles by the end of the decade.
    (end quote)

    Hydrogen fuel cells are a boondoggle. One would be better off with a straight electric car. Hydrogen isn't a fuel source... it's an energy medium, like electricity. To quote straight from another forum:
    Compare the energy efficiencies. What's the efficiency of directly charging a battery, and the battery releasing that energy? Very high - I can't remember offhand, but I'm pretty sure it's up in the 90 percentil range somewhere. Compare that to electrolyzing water (best case is 61%) and using it in a fuel cell (best theoretical case is 80%). Add those, and even ignoring the energy required to compress the gas to incredibly high pressures, the maximum possiblie efficiency is less than 50%. Real world efficiencies will be in the 30% range (not much better than a gasoline engine). So, you have to produce 3 times as much electricity to "charge" a fuel cell car to the same amount of recoverable power as an electric car - getting 3 times as much pollution. When you compare the ranges of fuel cells and electrics, fuel cells only win out by a tiny margin. It's amazing that people have been convinced they're the thing to focus on - in real world performance (even if fuel cells eventually come down in cost by a factor of 50 so people can afford them), they're only marginally better than electric cars, and require 3 times as much energy input.
  • nippononlynippononly Member Posts: 12,555
    the primary focus is efficiency though - it is the source of power. Mainly, getting away from petroleum use is the goal.

    If electric vehicles were powered entirely by renewable sources like wind and water (and sun) and had a range of 300-400 miles, they would be the perfect goal to shoot for. That may yet happen in the far distant future, but for now fuel cells offer the advantage possibly of not burning oil to achieve mobility. Even natural gas would be a small step in the right direction, although they are not there yet.

    Using a renewable energy source at 50% efficiency is still way better than using a non-renewable source (Petroleum) at 100% (which we don't anyway)

  • natescapenatescape Member Posts: 176
    nippon, where does the hydrogen come from? The "cleanest" way to get hydrogen is by electrolyzing water with electicity generated by solar/wind/hydro. But the Bush plan puts almost nothing into such renewable energy resources... almost all the funding goes to getting it from fossil fuels.

    The second law of thermodynamics says that whenever you convert energy from one form to another, you lose energy. So if the hydrogen comes from fossil fuels, we'd be better off just using the fuels in a combustion engine. Or if we get the hydrogen from electolyzing water, we should just run the car on that electricity.

    We can already power modified diesel engines on compressed natural gas. Why LOSE energy to turn the natural gas into hydrogen? Just do CNG. Either way, we're still burning a non-renewable fossil fuel. The fuel cell car just does it less efficiently than the CNG diesel.

    Or, better yet, just do biodiesel. :)
  • nippononlynippononly Member Posts: 12,555
    Bush is an oil man, so of course he pushes infrastructure changes that still depend heavily on fossil fuels, but that will hopefully change when the administration changes again...

    You are right about the fuel cells of course, but the one detail you left out is the smog emissions, and the point-source vs non-point-source thing...it is a lot easier to control the emissions of factories making electricity than the emissions of a billion little poorly maintained cars driving all over the place - this has been part of the push of alt energy programs for cars for a while now.

    Think of the fuel cells as being a really big onboard battery pack. If it works out, we will finally have electric propulsion, but over a range bigger than any battery pack we are capable of building. I personally think electric vehicles would have been a lot more popular if they had an operating range of several hundred miles and a refueling time as quick as gas cars. Both are crucial, and both can be met with the fuel cell proposition.

    It's my first TDI...since I passed up on the Hybrids and the Toyota Echo...overall...If I could afford it when it's available...I'd get the Toureg V10 TDI as a second car. The one of the reasons I got the TDI because of the driving experience. It's more fun to drive than the Prius, Insight, or Echo.

    nippononly:
    Based on my experience on my previous car (88 Camry V6)....after 90k miles the stuff coming out of the fuel filter was not pretty. In a perfect world, everyone will fill up with perfect gasoline, there would not be a concern for changing the fuel filter. Of course that is not the case...at times we get a bad tank, at times we unknowingly filled up a tank some time after the gas station got more fuel....

    Changing the fuel filter is preventive maintenance...plus a filters clog sooner or later. There's no other place for solid impurities to go, except for in the trash when you replace it.

    Hybrid Fuel Cells
    Toyota's FCH-V....what's its hydrogen source? Ultra refined gasoline. This is the current feasible hydrogen source for hydrogen, in Toyota's case
  • nippononlynippononly Member Posts: 12,555
    Toyota uses two filters - the other one is attached to the fuel pump intake and located in the tank - that is why it is not necessary to ever replace the in-line filter.

    Gasoline is the source for all current working fuel cell prototypes - that is why this technology has a long road to travel before there is any advantage to it.

    City cars however should not be as expensive as the hybrids tend to be in my opinion.

    I don't think people buy Corvettes for long drive either. Do they? They are expensive too! As for cost, it will eventually go down. Just watch.

    Diesels at least get reasonable fuel mileage in the city and can do quite well on the highway.

    Although diesels get good mileage and low end power, EPA isn't very high on rating the diesels from environment point of view.
    Civic HX: 44 mpg (highway). At $1.60 per gallon, 1000 highway miles will cost $36.
    Jetta TDI: 49 mpg (highway). At $1.70 per gallon, 1000 highway miles will cost $35.

    Yes, one would save $1.00 per month by choosing the diesel over the gasoline powered car. Now, I would love to see IMA applied to Civic HX. It will only improve the output. It will add cost as well, but to get to Jetta's price, $5K is available to play with! With electric motors, low end torque improves. With gasoline engine, top end performance is retained. That said, I would love to see gasoline-electric hybrids evolve. Diesels have had how many years of advantage?

    8u6hfd
    But...currently, given the availability of hybrids in the automotive market...it's gas-electric.

    I don't think we limit ourselves to the present when we talk about diesels. We even visit the realms of fuel cell. So why is it only the present when it comes to hybrids? Let us be consistent.

    That said, I don't keep up with hybrid power train development as much as many here would do, but I'm sure some automakers already have diesel-electric concepts.

    Honda is about to unleash its first (home-grown) diesel effort in Europe. Could they do diesel-hybrid in the future? Yes.

    Why are many against "recycling" the otherwise lost energy? Even in my car, I would love to have the feature of idle stop, courtesy of electric motors, a fantastic thing. The same can be adopted for diesels.

    And since "hybrid" is the term here, and can be applied to gasoline, diesel as well as fuel cell vehicles (yes!), why are we discussing the maintenance aspects of gasoline versus diesel engines (and to top it off, completely irrelevant comparisons as well, going down to the type of spark plugs used)? How does an electric motor stack up in terms of maintenance compared to a diesel or gasoline motor?

    BTW, another point about discharge rate of batteries was brought up earlier. There is this another thing called an ultra-capacitor, likely to be used in the next upgrade of hybrids. It improves the efficiency of the entire charging/discharging process! A few prototypes, since the launch of Prius, Insight and Civic Hybrid have already used them. In fact, Honda FCX uses it as well.

    Things will only get better, and there are ways to go before gasoline/diesel-electric hybrid technology can be near the development of current gasoline/diesel technology.

    So we use MORE energy in exchange for the possibility of less pollution? Yikes. Sounds like a losing formula right there. And, frankly, the primary issue shouldn't be pollution (which is still obviously quite important), it should be fuel effiency and fossil fuel reliance.

    Power plants are often not all that clean. Trust me on this one... I live two towns away from a massively polluting power plant. It probably puts out more PCBs and pollution than all the cars in the area.

    <rant class="slightly unhinged"> ;)
    And, listen, we need to start weaning ourselves off the teat of fossil fuels TODAY. At current rates of consumption, there's no way we don't rip through ALL our useful fossil fuels in this century. At the end of the century we will either a) have transitioned to renewable fuels (most likely solar, wind, and hydro-electric) and conservation b) perfected nuclear fission or c) collapsed into an anarchaic Mad Max or Amish future, with MASSIVE human die-off in the meantime. This could be a VERY ugly century.

    the electric motor requires NO routine maintenance...I guess that means it requires less maintenance than the diesel or the gas, eh??!! :-)

    Diesel is dirty right now. That isn't the debate however. If any have bothered to research this Biodiesel that has been mentioned it is already an alternative fuel source that can be used in diesels. It gets fuel mileage very close to petrochemical diesel, notice they don't call it fossil fuel anymore? So a renewable fuel source is ready and can be had today. Diesels can use it today. No need to have a 124 cell battery, or what ever it now is, to try to recycle. You can run either diesel is necessary. They aren't taking a loss on every diesel like they are on most hybrids and the technology is easier. what is a better solution? One that is right in front of you and can start solving the perceived fuel dependency today, or one that hasn't proved itself and is still years off of being accepted world wide? Do we as consumers take the hard path? Must be other consumers we are talking about. (Texas must be a high sulphur state, California has Diesel at $1.99 and Premium at $2.13. Today, but by the end of the week who knows? we could own a whole lot more oil wells.)
  • robertsmxrobertsmx Member Posts: 5,525
    Diesel is dirty right now.
    If it is now for gasoline-electric hybrids, let us keep the now for diesels as well. That said, may be we will have choice between gasoline, gasoline-electric hybrids, (bio)diesel-electric hybrids, diesels, or some other form of fuel in the future.

    They aren't taking a loss on every diesel like they are on most hybrids and the technology is easier.
    Which hybrid is selling at a loss now? Both, Toyota and Honda, are earning profits. That said, any form of entrepreneurship requires initial investment. It doesn&#8217;t begin with profit.

    Right now biodiesel is available. There is a supply depot not more than 50 miles from my house. It is renewable and clean even in current diesels. Toyota claims to be making a slight profit from the Prius but then they are about to replace it with the next generation and Honda is making no such claim with the Civic. GM is making a profit selling hummers and has from day one. I see Texas is doesn't use low sulphur fuel just yet from looking at the green car site so I can also see fuel is less expensive there. However, back to the point. Diesels can already use a alternative fuel in biodiesel, it is available in most states. And current diesels do handle about as well as current gas ICE cars. Something current hybrids can't claim. So diesels seem to have the inside track. States that don't now have low sulphur fuel can't be considered as being as concerned with being green as states that are one would think. But even if some are pzero cars are already available and the Prius as of yet is not one. So current hybrids are, slow, one is going away as we type, and more expensive. Diesels offer right now alternative fuel usage, are in larger use, and have a proven track record for dependable engines. Current diesels use biodiesel but your current car can not be converted to hybrid. So which is the easier answer to oil dependency and clean air? Or are we just willing to believe that hybrids are the "best" the manufacturers can do? I believe it is the least they can do, and so that is why they do it. Just from my perspective.
  • natescapenatescape Member Posts: 176
    There is no firm evidence on production costs for Toyota and Honda. But odds are good they subsidize the hybrids to keep the price down. And I don't mind that at all... good for them! Just realize that the company is taking a loss on the cars.

    I personally think diesel hybrids running on biodiesel is about as clean and renewable as we're going to get for a while.

    http://www.spectrum.ieee.org/WEBONLY/publicfeature/jan03/thev.htm- l
    "Although regular hybrids can improve fuel economy by up to 400 percent, that advantage comes at a cost: with its dual power plants, Toyota's Prius is said to cost far more to make than its $19 995 sticker price. (A Toyota spokesman declined to comment on the Prius's production cost or to say whether the carmaker is turning a profit on the vehicle.) "

    or
    http://www.insightman.com/opinions/amazing_car.htm
    I cannot commend Honda highly enough for taking the profit factor out of the equation. The incomparable Honda engineering team has done a marvelous job of balancing the physical trade-offs to create a car like no other in the hundred-odd years of the automobile and Honda management has bought into the project in a big, big way by pricing the Insight below $20,000. In reality, it should cost more than the $32,000 S2000 sports car, but Honda knew I couldn't afford a car that expensive (they must have read the Insight survey answers I submitted on their website) and made the ultimate trade-off: a fantastic car that will make no profit.

    or
    http://www.colby.edu/~dlfouche/electriccars.html
    However, there are some problems with these hybrids. This car is mechanically more complicated because it has to have two different types of engines and clutches. There is also a complicated computer system in the car to control the clutches and motors. This causes the manufacturing cost of the car to be quite high, about twice what a regular car sells for. The reason why so many people are buying Priuses is because Toyota is selling them at a loss.

    thanks for the sites. I was sorry to see the failure of the pure EV. It seems as if we decided to toss in the towel and say, we can't do it. I admit that failure has turned me to the alternative fuel idea. If we can't make a EV maybe at least we can make a alternative fuel vehicle. The idea of Biodiesel was a surprise to me in that I thought the solution would come from any direction other than diesel. I don't know if we are still looking for solutions or have decided that hybrids just use less fuel so that is all we can do. Only time can answer that question.
  • robertsmxrobertsmx Member Posts: 5,525
    Honda may release a hybrid light truck soon

    And Civic Hybrid has been selling alright, so there is no plan to replace it, yet. 2200 units last month is quite good, IMO. It has been in the market of just over a year, right? That is no time to think about replacing a car. Civic follows 5-year redesign cycle, but may get some tweaks in a year or two.

    And now the news is that Civic Hybrid may be offered in Europe. And another news may be a big one, and has been in Europe... a performance Accord using gasoline-electric drivetrain. The AWD prototype at Geneva had 350 HP, but production variant could be like 240-260 HP as the Accord Type-R replacement. And we could see it as a higher trim of TSX as well!

    OTOH, Honda may not bring its diesel engine (it is a 2.2 liter CTDi pumping 140 HP/245 lb.-ft) in the USA any time soon. The release in Europe is a few months away.

    The Toyota transmission is actually quite simple, I really wonder whether the guy did his research before writing this. It's a simple planetary gearset! This kind of device has been used for years and years in auto transmissions, they're very solid, and due to its very nature the so-called complexity of the ECU is not that high. It's actually a pretty smart design, in the KISS way of thinking.
  • 8u6hfd8u6hfd Member Posts: 1,391
    Toyota automatic transmission
    Yes, Toyota uses a planetary setup for ages now. I don't believe this is the case for the Prius as it uses a CVT.

    Profit margins
    When Toyota launched the Prius in 1997 for Japan, they were selling it at a loss. At that time, the technology and manufacturing of was not matured....flash forward to today, as Toyota "sold" its hybrid setup to many companies...more production means lower unit costs.

    Biodiesel, made primarily from rapeseed (Canola) oil is popular in Europe. It is sold along side of petrol diesel.
  • idletaskidletask Member Posts: 171
    Yes, it is a planetary gearset in the Prius, look here. In effect, the way it is operated gives it infinite ratios, hence CVT. But not a CVT as we know it.
  • robertsmxrobertsmx Member Posts: 5,525
    When Toyota launched the Prius in 1997 for Japan, they were selling it at a loss.

    That is true for any new/redesigned vehicle. Initial (R&D) costs are high so it takes a while to get the returns. Honda S2000 was a hot car when it was unleashed in 1999, and so was the redesigned Odyssey. It took about six months for these vehicles to turn in profits.

    The costs and complexity associated with hybrids using electric motors is exaggerated, IMO.
  • 8u6hfd8u6hfd Member Posts: 1,391
    Toyota took a huge loss per car selling the Prius in Japan. THey sold for well less than the cost it takes to produce one. When they priced it back in 1997 for Japan it was two options:

    1. Price it to have a profit margin
    2. Price it to lose money, but have it accessible to consumers.

    The first case is simple, automakers do this in general. For the Prius, as before I mentioned, the cost of producing the technology was very high, due to small production numbers....it would have put the car out of reach for most consumers Toyota was targeting. If they couldn't sell the car because the high pricing...they lose money anyway.

    The second case, is what Toyota did. Even though they were taking huge losses per car, they felt the long term benefits to the company outweigh the initial losses. Toyota's hybrid system is gaining acceptance, thus why a few years later, Toyota introduced the Estima Hybrid, and soon the Harrier (Lexus RX330) hybrid. Also the Toyota hybrid system is used for the Escape Hybrid, as well as upcoming Nissan hybrids. Now because of the widespread acceptance and customers, production of the Toyota hybrid system can increase, and drive down unit costs, and finally get their return on investment, and get profits.

    Look at the technology you see in cars today....many of the features, like power windows, locks, ABS, airbags, etc., when first introduced they were high cost options. Today since so much is produced, they are features that don't cost much nearly as much as they were first introduced.
  • robertsmxrobertsmx Member Posts: 5,525
    8u6hfd

    I understand what you are saying, but my point still stands, and not much different from your. You can't expect something new to start adding to profits immediately. If Prius is turning profits, at some point, the initial investment was recuperated. And if is turning profits today, it was priced to have a profit margin, not to lose money as we continue to wait for the other models that build upon the investment Prius started with.
    Honda is developing its first diesel engine for launch in European Accord later this year. Although the engine will be shared by some other models later, do you think it will be priced with a profit margin? Or with an effort to make it accessible to the consumers? Either way, it is not going to start delivering profits immediately, whether or not it is shared with other models.

    Intel went from the 486 processors to the Pentiums as a new technology. I bought a board and CPU myself right after they came out. Price was only slightly higher than a 486 and it was much faster. Intel made profits right off the mark it seems, and prices even went down when the 90 came out. Hybrid is not a new technology in that it hasn't been tried before. Diesel trains have used a hybrid system for years. Ships use a hybrid system now. Both perform better and are more fuel efficient than their non hybrid cousins. To believe a company like Toyota made a vehicle that far outstripped their expectations in the first year and by year three a company that can produce close to 400,000 Camrys couldn't make more than 20119 Hybrids for the US seems silly. Even Chrysler when they discovered how well the PT Cruiser sold the first year was able to increase production to 150,000 units by year two. John has said they are doing so well in Japan and they have had five years to capture the small car market in Europe but alas diesels have done much better. In the US they decided to limit production because they didn't want to flood the market or what? People didn't want a little commuter so the Insight failed. Not as a car but as a car people wanted. Is anyone going to look in the mirror and say they intended the Insight to spend three or four years on the market and then disappear? As someone has already said there are places where you can by biodiesel right next to petrodiesel. Renewable fuel and a proven engine, how can that be a bad idea?

    This is an excellent example of upgrading an existing technology and the costs associated with it. Expect the same with hybrids.

    Intel made profits right off the mark it seems, and prices even went down when the 90 came out.
    Intel didn't start with Pentium but built upon an existing product. Still, the initial investment was not recuperated with the first sale of the chip, I can bet on it.

    Hybrid is not a new technology in that it hasn't been tried before. Diesel trains have used a hybrid system for years. Ships use a hybrid system now. Both perform better and are more fuel efficient than their non hybrid cousins.
    That's the point. I did mention that hybrid technology has been around for a long time, just not in automobiles. And this is critical because hybrids are still perceived as something very different, and it is a cautious market at its best.

    To believe a company like Toyota made a vehicle that far outstripped their expectations in the first year and by year three a company that can produce close to 400,000 Camrys couldn't make more than 20119 Hybrids for the US seems silly.
    One step at a time is the key. Business decisions are (should) never made to flood the market with products, no matter how successful they are. Honda can sell 400,000 Accords per year, does not mean they can flood the market with 400,000 Odyssey, although the demand is strong. TSX target is only 15K per year, TL sales were targeted at 40K when it was redesigned, and increased to 60K as sales caught up. Insight arrived with projected sales of 5K per year, Civic Hybrid takes it up a notch and projected sales volume is about 25K for the year. So, how many Jetta TDI does VW sell in a year in the USA?

    People didn't want a little commuter so the Insight failed.
    Did it? It was never meant to be a mainstream product. It was a stepping-stone and has served its purpose.

    As someone has already said there are places where you can by biodiesel right next to petrodiesel. Renewable fuel and a proven engine, how can that be a bad idea?
    It is not a bad idea, but use of electric motors to assist a proven technology isn't either. That said, somebody here may be living a few miles away from hydrogen re-fueling facilities (South Cal), that does not mean Honda FCX can go mainstream. And it won't (again), because FCX is another stepping stone in the fuel cell vehicle development program.

    That's pretty cool. Thanks!

    However, the two of the three most important details were not included... what region of the country you live in and whether you have a manual transmission or an automatic.

    (Type of driving was the third.)


    I'm driving a manual TDI. My driving is typically throughout northern TN, KY, OH, IN, MI, WV.

    I have a brother-in-law with an automatic TDI with about 140k miles on it last time we chatted. He claims his average sits right around 43mpg, however he doesn't zoom-zoom like I do. I spent about three weeks driving his car semi-locally around Ohio two winters ago. With my style of driving I got around 40mpg on two fill-ups. BTW, once I learned the tranny and it learned my driving style, we got along quite well. I would put the performance very close to a stock manual TDI, although substantially slower than my modded TDI.

    A very helpful study...

    The Diesel Dilemma
    Diesel's Role in the Race for Clean Cars
    Union of Concerned Scientists, 1/6/2004

    Enjoy!
  • moparbadmoparbad Member Posts: 3,870
    My conclusion after reading the article is that UCS is promoting political policy and not sound science. The inherent thermal efficiency of a diesel engine is ignored. The cost of diesel engine is exagerated. If diesel engine production is increased, cost will decrease. Diesel engine is not overly complex compared to gasoline. Main increase in cost is need for additional mass to withstand combustion and turbocharger/intercooler. The fact that diesel is renewable fuel that may be refined from plant oils or animal fats is ignored.
    I do not know if the fuel of the future will be hydrogen or diesel or something undiscovered, I do know the Union of Concerned Scientists would IMO be better named the Politicians Hiding Behind Science.

    RE: Sadly, once you leave the city and deplete your batteries, your techno-wonder hybrid is just an over-weight, under-powered vehicle that consumed more resources in its creation than a few dozen "normal" cars.

    For those who don't understand how a hybrid works, it captures the vehicles energy when slowing by re-charging batteries instead of just converting kinetic energy to heat via the brakes.
    This battery power is then used to help accelerate again via an electric motor.

    It sounds good in theory, but I have 2 gripes:
    - the manufacturers "cheat" in the comparison with "normal" cars because they also perform additional mods to reduce weight and reduce drag. If they did that to their other cars their mileage would improve without the trendy hybrid option.
    - the manufacturers have chosen to use the most technically advanced, dense, electric motors. This is a good engineering decision, but not a good environmental decision. What are the world stocks of Niobium like? How much Molybdenum is available? If you though Aluminum was expensive to produce (making aluminum is akin to mining rust and then applying huge amounts of energy to reduce it to Iron and Oxygen) then you haven't seen what these other metals require.
    Toyota builds hybrids as a marketing gimmick to make up for the fact that they had the largest selection of SUVs for sale in the US a couple of years back (I'm sure GM has passed them now that they're even putting every GM badge onto flavours of the Saturn VUE!)
    Honda does it to play catch up with Toyota.
    Both sell at a huge loss, but its a marketing gimmick remember, not a profit center.

    Who wrote that bogus piece of garbage?
    When they talk about cost, they are talking about "old" gas technology, and when they talk about mileage, they are talking about "future" gas technology. Here's a hint for fair journalism: PICK ONE OR THE OTHER!

    The new "direct injection" gas engines have the injection complexities of diesels, but are burdened with the additional electrical and maintenance issues of spark-plugs.
    And there was no mention of the added pollution caused by gas engines in bad need of a tune-up! (a real and significant problem on our roads)

    And there was also no mention of the additional longevity of the diesel engines. Once again, a study that assumes that cars just grow on trees in Japan and there is NO energy/material/resource/environmental costs in manufacturing them.
    In reality, new cars (which pollute less in operation) are consuming much more energy and generating MORE pollution in their manufacture than the ones they replace.
    There is a significant environmental advantage to keeping cars on the road longer and amortizing the damage from creating them over more passenger miles!
    So, compare a diesel powered car that is still efficient at 300,000 miles to a gas powered car that is not so clean burning at 200,000 miles.
    But the editors don't have a clue. They're too busy chasing "the sound bite" to invest the time or energy into examining the big picture. Hype beats substance ... again.

    How did the oil companies jack Diesel up to the price of regular?
    For X barrels of crude, you can generate "G" barrels of Gas or "D" barrels of Diesel. I read a figure once that indicated D ~= (6 x G) ... meaning that every gallon of gas could be replaced by 6 gallons of diesel for the same price!
    Its obvious that the oil companies have artificially inflated the price of diesel fuel to curb sales of diesel vehicles in order to maintain their high sales volumes of gasoline.
    If diesel was fairly priced at about 1/4 the cost of gas (US$0.40 a gallon) then the large resultant shift to diesel vehicles (which consume less fuel) and the lower revenue from diesel would severely cut into oil company's profits.
    Plus, the huge reduction in the demand for crude would mean that the US wouldn't have to import oil, driving prices (and profits) down further.

    That bogus "diesel dilemna" article looks like the that article in the computer world that says developing programs on Microsoft Windows costs less than on Linux ... oh yes, we forgot to mention that the study (which goes against ALL user experience) was funded by Microsoft.

    I wonder which oil company paid for "Diesel Madness!" (as in "Reefer Madness")
  • pusterracingpusterracing Member Posts: 186
    Everyone talks about how much more you pay for the Diesel engine off the bat.....that you have to keep the car for the life of the car to make up the difference....well....from KBB.com here are trade in Values..apples for apples. I used a 2000 Jetta GLS (2.0gas, the standard engine), 2000 Jetta GLS Turbo (1.8gas) and a 2000 Jetta GLS TDI (1.9L diesel), 60K miles, and all options the same, excellent condition. TIV on the GLS 2.0 was $8350......TIV on the GLS 2.0 was $8575......TIV on the GLS TDI was $10,950....a difference of up to $2600 at trade in. Not bad for paying an extra $1050 off the bat (MotorWeek http://www.mpt.org/motorweek/reviews/rt2102a.shtml). This isn't to mention that I pay $0.20 a gallon cheaper for my fuel, and I observe 43mpg in mixed driving and 48mpg on the hwy, and I can easily get 400K miles out of my car.

    I am all for the Hybrid cars, but I just cannot see paying $3000 over sticker and waiting 6 months to get a car (Toyota Prius), when I can have a great riding, comfortable car for right at $21000 with all the bells and whistles and still get over 40mpg around town. These aren't your Daddy's Diesels......things have come a long way since the 70s. I just wish people could see that.

    Proud owner of a 2004 Jetta GLS TDI.

    the manufacturers "cheat" in the comparison with "normal" cars because they also perform additional mods to reduce weight and reduce drag. If they did that to their other cars their mileage would improve without the trendy hybrid option.

    Not necessarily true. In case of Honda, your gripe may have been true if you consider Insight. But I doubt getting 60+ mpg would be possible just by reducing weight and drag. For one, you would be left with a less powerful engine (Insight uses 1.0 liter engine, and electric assist helps create instant power).

    In case of Civic, Honda added IMA, additional sound insulation and underbody panel on a regular Civic. OTOH, Honda HX (regular &#147;high mileage&#148; Civic, EPA rated 36/44 with manual) gets several cost cutting measures. I just don&#146;t see how adding IMA would not improve the EPA rating established for Civic HX.

    the manufacturers have chosen to use the most technically advanced, dense, electric motors. This is a good engineering decision, but not a good environmental decision.
    Nope. Honda IMA is essentially a compact and thin DC brushless motor. There is a lot more metal needed to deliver a diesel engine.

    So, compare a diesel powered car that is still efficient at 300,000 miles to a gas powered car that is not so clean burning at 200,000 miles.
    But the editors don't have a clue. They're too busy chasing "the sound bite" to invest the time or energy into examining the big picture. Hype beats substance ... again.

    That said, any ideas why diesel locomotives use hybrid set up? I believe those engines are series hybrids, running primarily on electric motor, with energy source being diesel.
  • nippononlynippononly Member Posts: 12,555
    not to mention that while Prius does have a lower Cd, it is not lightweight by any comparison with other cars near its size. It is almost 3000 pounds, a little more than the Matrix and Focus five-door, a little less than a Subaru Impreza.

    Plus, cars are getting more and more slippery as years go by. The Prius 0.26 will be matched by other non-hybrid models within a few years I am sure.

    Acura TSX is already at 0.27 (co-efficient of drag) and so is Infiniti G35 with aero package. Lexus LS430 might be too.

    of unanswered questions with both technologies. We have no idea how diesels will play out in the future with synthetic or renewable fuel. We also have no way of knowing how we will dispose of the battery packs in hybrids. Diesel electric trains is one thing. Both power sources are recyclable. But hybrids we see today have a hazardous waste problem. As an example you can no longer throw your old computers in the landfills. The monitors are registered hazardous waste. Unless you send the monitors to China, one of the few places that reuse them, and much of the computer boxes to Europe, Belgium has a method to reuse the precious metals inside some of them, you have to pay to get rid of them. I have read that only about 40 percent of the homes in the US have computers. We do have 17 million new cars sold every year and if half of those were hybrids today what would we do with the hazardous battery packs they will produce in the next five years? What ever clean air benefits they would have produced would simply be transferred to the ground. It is pure speculation at this point that hybrids will be a solutiion for the long haul. We will only be able to see how it plays out over the long haul. with the information we now have at our disposal I would be pulling for diesel. Because even if we converted hybrids to diesel and burned biodiesel we would still be left with the battery packs. Just my take with what we know today.
  • robertsmxrobertsmx Member Posts: 5,525
    The demand for batteries has been going up anyway. From film to digital cameras, from &#147;line&#148; phones to mobile, and so on. In case of hybrids of the future, this may be a mute point. I have a feeling that we will start to see use of ultra-capacitors more than batteries in the near future, in hybrids.

    That said, replacing 120 batteries (1.2V each) after ten years may not be any different from using 12 AA sized batteries per year for next ten years. If hazardous material concern were valid, we might want to take into account the additional &#147;hazard&#148; that refineries would spew into the atmosphere to deliver 40-50% more gasoline/diesel for 17 million cars. In the end, the premise of hazardous waste from use of hybrid technology may be pointless.
  • boaz47boaz47 Member Posts: 2,747
    Or maybe it isn't pointless and just for once we might want to see if hybrids are a free lunch or do we pay for it some other place? Just because we have to find a way to dispose of the cell phone batteries anyway does not mean we can ignore the 100,000 or more battery packs that the current hybrids use or will be using in the short term. Transferring the pollution from the air to the earth may not be a trade off worth making. I am sure whoever thought that every home could have a computer never thought the monitors would be a issue either.
  • robertsmxrobertsmx Member Posts: 5,525
    10 years is a long time. Can you tell how much "hazard" 100,000 non-hybrid vehicles will cause (directly, and indirectly) over 10 years compared to those packs with 120 batteries in each?

    If you can't, what is your argument based upon?
  • mirthmirth Member Posts: 1,212
    ...because there are fewer hybrid batteries then that means there's no environmental problem? Hardly. Plus, with all these car makers ramping up their hybrid production, there's gonna be more that 100K of these things out there, and they're a bit bigger than cell phone batteries.
