    Let me do a reality check. Based on the reality difference, (of 8k, 27k vs 19k= 8k)@ 2.09 # 2 diesel bought last night, 8k will buy 3,828 gals of fuel. At 50 mpg, that is 191,388 miles.

    > 27k

    Why are you forcing the perception that every owner will not only buy the extremely-well-loaded version of Prius, but also pay above MSRP?

    That is wrong.

    Before the gas price spike, most were paying MSRP, and many were just medium packages. Some people even managed discounts.

    I know people that got the $19,995 price. Why are they being misrepresented? And why are you insisting on a "today only" attitude? Supply will eventually catch up with demand.

    Buy the way, the exact scenario happened when the Ford Explorer was brand new.

    I don't see where ruking1 is exagerating. See the link below. That dealer has several Jetta TDI's in stock at $19,245. Your assuming that someday Toyota will build enough Prius vehicles to bring the price back to $20k. I doubt it, when they got people crazy enough to pay $27k. If you can find one, that is what you will pay. The Japanese are masters at short supply to keep prices up. That is why they have one of the highest profit margins in the auto industry.

    "I know people that got the $19,995 price. Why are they being misrepresented? And why are you insisting on a "today only" attitude? Supply will eventually catch up with demand."

    Then it will be easy for you to recalculate the numbers? Or is it because Prius doesn't come with with a free calculator in the package?

    As for the "today only" attitude if I can buy today and run a Prius for a forward price of what I paid for the Jetta ( mine was 17.6 if I remember correctly before tax and tip) :(. I'd be a buyer! Of course if you project cheaper than 17.6, I wouldn't want to over pay?

    Its hard to imagine that in just one year Toyota and Honda have sold MORE Hybrids than TDIs sold in the past five years. I wonder why? Maybe VW needs to get a better PR firm!

    Just found out that my best friend's colleague just bought a new Jetta TDI and is averaging a nice 43 MPG overall. He has the five speed and drives conservatively. He test drove the auto but said it was a little sluggish. That's one nice feature about the Prius. The CVT is quite responsive compared to a conventional auto tranny.

    The TDI may be a great car for people who solely are looking for fuel economy. Other than that, I'd be yawning all the way to work. I need toys and that's why I like the Prius. If VW was smart they would advertise the TDI as an alternative to the Prius. Imagine all the interest they'd generate? All they have to do is add SE (can't have start smart because of the way the diesel starts I suppose), NAV, Bluetooth, etc. I'd bite!
  • ruking1ruking1 Member Posts: 19,826
    TDI's judging by the vehicle population is an uphill sell! 4 % in the USA is the VW population! In the overall passenger car/light truck market it is less than 1% and I think even that is optomistic!

    Of course interstate commerce is almost 100% diesel! :)

    On the adult ADD, sorry that is off topic! :) And you should be paying attention at 90-100 mph anyway! :)
  • gagricegagrice Member Posts: 31,450
    Where did you get your sales figures? I assume you are speaking of just US sales, as VW and the TDI in particular are the largest selling cars in Europe. Also because of inconsistent regulations by the CA legislature TDI sales are restricted. If they did not allow ugly cars to be sold in CA the Prius, Insight and Pontiac Aztek would not be allowed across the borders. I will withhold any other judgment until I hear you praising your Prius after 100k miles.
  • ruking1ruking1 Member Posts: 19,826
    "I will withhold any other judgment until I hear you praising your Prius after 100k miles. "

    I would also agree! To me, the new frontiers also should include more emphasis on longevity. Two metrics that are pretty easily met 1. the "warranty period" 2. most all cars, with any reasonable care should easily do 100,000 miles. 3. It is the after part that has a higher priority for a host of reasons.
  • gagricegagrice Member Posts: 31,450
    Longevity is a vital part of emission control. The pollution that is spewed in the air to produce a vehicle is significant. Throwaway vehicles like the Prius are unacceptable. I really believe the auto makers are using the hybrid as a smoke screen while they research some of the better ideas and concepts available. I cannot understand why on a forum of this scope there is not a thread discussing the Honda Civic CNG. According to the EPA it is the cleanest internal combustion vehicle ever tested. The natural gas-powered Civic GX earned the title of "America's Greenest Car" by combining high-efficiency with near zero emissions performance.

    Beauty is in the eye of the beholder. I am referring to US Sales [non-permissible content removed]. Secondly, your comment is indicative of your maturity. Perhaps people may look at you as being ugly, but I respect your opinions. Apparently Americans in general are smitten with the Prius' looks as dealers can't keep them in the lot! The Aztek is another story.

    "The TDI may be a great car for people who solely are looking for fuel economy. Other than that, I'd be yawning all the way to work. I need toys and that's why I like the Prius. "

    Beauty is indeed in the eyes of the beholder, and there is no accounting for taste.
    If you are stuck in stop-and-go traffic, "toys" may be welcome diversions. On the other hand, German engineers have a reputation for building "driver's" cars.

    I like the Jetta TDI's fuel economy, but LOVE the way it drives.
    Busy little motor-assist guages and pictograms is what would leave some of us yawning after the first few days of wonder.

    Go to the Escape Hybrid Forum.

    I posted a summary of the Wash Post Review of the Escape Hybrid.

    Driven under REALISTIC Conditions,

    it averaged 30 mpg city and a DISMAL, unacceptable, 23 mpg Highway.

    WHile many people I know ROutinely get 28 mpg Highway from Escape-sized SUVs that cost 10,000 LESS than the hard-to-find Escape Hybrid (they will build only 20,000 ofo them the first year, less after that)
  • usbseawolf2000usbseawolf2000 Member Posts: 759
    Where is the link? I wish they also test drove the V6 version and compare it side to side to get more conclusive results. Remember, realistic driving means 10%-15% lower than EPA ratings for any car. BTW, 2005 Escape AWD I4 and V6 highway fuel economy are 22 MPG. Why the same? I would expect 4 cylinder version to get higher.

    Hi All:

    ___Well someone is making Diesel’s SULEV anyway … The Urea injection method requires a tank to be filled every 50 or so thousand IIR from my reads of the tech last year but it works. I wonder if you can just pull over to the side of the road, unzip, and … Well you know what I mean ;)

    Those toys include, smart entry/exit, NAV, bluetooth, CVT tranny (quite responsive), Toyota reliability, great driving position, XM radio. Had an Audi Allroad I got tired of after six months. The TDI will be on my list to buy next year as a second car for long trips ( I like having two cars). I'll alway favor the Prius though. No doubt, the Germans make great driver's cars. I've driven the Jetta and I know. I still LOVE my Prius.
  • usbseawolf2000usbseawolf2000 Member Posts: 759
    If hybrids manufacturers are smart, they would advertise or market hybrids in such a way. Come to think of it, it might deserve it's own message board thread. =D

    "Toyota reliability, great driving position,"

    A matter of perspective and can't be classified as toys.

    "smart entry/exit"

    The little button that unlocks the car/turnk is smart enough for me

    "NAV"

    Got it, it's called Rand McNally

    "bluetooth"

    Don't need to be talking on the phone while I'm driving anyway...should concentrate more on the driving

    "CVT tranny (quite responsive), "

    No Thanks...I like to shift.....

    "XM radio"

    I prefer the Free Kind that doesn't require subscription....

    So see....every driver is different....I don't need a bunch of frills to be happy with my car. Heck, my racecar doesn't even have a speedo or any seats but a drivers seat let alone A/C or power windows. I still enjoy driving it. And without all of the "Toys" I still love driving my Jetta TDI...all 100hp/177lbft torque and fun to drive aspect of it.

    Just a matter of personal preference.

  • norrmanndonorrmanndo Member Posts: 81
    I'm not going to put anyone down who buys a Prius. Thank you. But I'm still more interested in Clean
    Diesel (locally grown); mainly because it helps a little with our reliance on middle east oil, and secondly because it is great technology without the false image.
  • djasonwdjasonw Member Posts: 624
    It's pretty difficult to find diesel fuel at a great deal of stations where I usually drive. My best friend who has a Merc TD300 always has to search around for them. Then there is the issue with filling. If you don't use gloves you're bound to get the mucky oil fuel on your hands. Then you have to be careful when filling, as the fuel foams up. No thanks. I've decided a diesel is NOT for me. My second car will be the A3 when it arrives here (hopefully). The way it looks now, hybrid gas engines will always have more popularity in the states than diesels.
  • tom21769tom21769 Member Posts: 63
    Pusterracing, you expressed my sentiments exactly!
    I had started to respond with almost exactly the same points (down to the "Rand McNally").

    Hybrid is a good technology, but not for every car. For a heavier vehicle (like many SUVs), doing mostly highway, modern diesel makes more sense.

    Another thing, if you're choosing a car for economy and longevity, does it really make sense to load up with expensive toys like a NAV system? Cool technology, I admit, but I bet they look hopelessly out-of-date in another 3 or 4 years, let alone the 10 to 15 I'd like to keep an automobile.

    So I think the Prius, in the way some of them are bundled and priced, is a rather contradictory package. Unless what you're really selling is gee-whiz gadgets to people with lots of money to spend. Once the bloom is off that rose, the same people will realize you can even more gewgaws in a sportier package somewhere else. Or get energy-saving technology in a somewhat more sensible package (base Prius, or Honda Civic Hybrid.)
  • john1701ajohn1701a Member Posts: 1,897
    Afraid to discuss HSD itself, eh?

    Instead, you feel the need to talk down the only configuration currently available.

    If your intent is objective, let's see some actual detail about the hybrid technology.

    Distracting people by talking down a specific vehicle accomplishes almost nothing. You'll have to do the very same thing all over again when each new HSD-equipped vehicle becomes available. Eventually, many will see right through that deceptive technique.

    HSD is Hybrid Synergy Drive. It is the design Toyota engineered to blend a combustion-engine with both a generator-motor and a thrust-motor, allowing for seamless & rapid switching of power needs. This is what should be the topic of discussion, not any particular vehicle package.

    I would also agree! While folks have not said this; the assumption seems to be that there will be no unscheduled maintenance to the Prius!!??? OK suppose I believe this fairy tale, the battery replacement at 150,000 at 140 a pop x 28 modules= 3920 will wake me up from that dream right quick! The other fairy tale would be OK Toyota or whatever OEM will swap out the batteries at 150,000 FREE!! :(:) WAY COOL! However that still leaves the issue of the so called up front premium!

    My assumption for planning purposes for both the Prius AND the Jetta TDI for example would be most likely WHEN, and how much!!?? These figures can be reasonably projected into a cost per mile!! Yet the Prius owners consistently and stubbornly refuse to even acknowledge cost per mile and instead talk only of the so called gee whiz technology!!?? So if it is true that batteries will be needed at the 150,000 mark then 3920/150k= .0261333 cents per mile for starters.

    The actual experience of PRIUS owners and also TDI owners can both be scary if you factor in that VW TDI's in the USA is a scant 4% and the Prius in numbers of 22k is downright even scarier!!
  • john1701ajohn1701a Member Posts: 1,897
    Why would someone replacing battery-pack modules 8 years from now pay debut prices? Why wouldn't they pay prices of that time instead?

    That would be around 2012. By 2010, Toyota has stated that every passenger vehicle they build will be offered with the option of having HSD. Production and competition will increase each year until then. How could the cost possibly remain the same, as you are have claimed? Every new technology is expensive at first, then it drops significantly as volume increases.

    Also, if it really was that expensive, why in the world would someone replace every module? Why not just 1/2 or 1/3 of them instead? That would obviously save them a bunch of money.

    "By 2010..."

    Alot of good that does for people planning on buying a vehicle now....in 2004. And alot can change in 6 years..plans go by the wayside, etc. It is nice to speculate on future plans (published and not), but why don't we stick to the FACTS of here and now? That is, if we want to be truly objective.

    YOU, nor I, have no idea what diesel techonolgy will be like in 2010, that is why there is no room for speculation, about any technology. You can spout of about..when this gets here..or Toyota/Honda/insert manufacturer here is planning on doing XXX by YYY....but until it truly happens, then it is only speculation. No matter what the propaganda says.
  • djasonwdjasonw Member Posts: 624
    I wonder how someone like me would calculate that. I have the extended 100,000 mile warranty over and above the hybrid warranty (paid $987 for POM). The way I see it, I don't pay for oil changes (my dealer pays until 36k). After that, I just pay for oil changes and whatever maintenance there is. There is no way the TDI can be cheaper under these circumstances.
  • djasonwdjasonw Member Posts: 624
    OMG.. that is SO LAST CENTURY. Get real... NAV units will be offered in most cars within ten years. Once you have NAV you wonder how you lived without it.
  • tom21769tom21769 Member Posts: 63
    The reason I was discussing a particular vehicle's packaging
    was because a previous poster argued that that packaging
    (NAV, bluetooth,etc. in the Prius) made it a more interesting vehicle for him.
    Can't argue with that - let's hear it for choice! - except to say that for
    some of us, when you focus on the actual driving characteristics
    of the alternatives (in addition to cost and these other issues), the VW TDIs are still a good option.

    So maybe we're in agreement. Let's talk about hybrid vs. diesel, instead
    of what makes a car more fun (Japanese electronic "toys", or German torque and precise handling).

    I've said it elsewhere: hybrid electric is a great technology, but so far appears to shine best in lightweight vehicles, in stop-and-go traffic. For the many Americans who drive heavier vehicles in mostly highway or suburban driving, a modern diesel engine may well deliver greater fuel economy improvements and greater longevity, in a system that is less complex and therefore simpler to maintain (assuming all other quality factors are equal).
    Granted, emissions are another issue.

    "I know people that got the $19,995 price."

    That's like saying "My sister's boyfriend's cousin's husband knew a guy that he worked with that got one at that price".

    "Why are you forcing the perception that every owner will not only buy the extremely-well-loaded version of Prius, but also pay above MSRP?"

    Because we have repeatedly asked, and repeatedly been ignored, for real world data on Prius costs. So, all we can do is observe what we see on the lots, by seraching the classified, and searching the internet. The average pricepoint is somewhere around $26,700 or to make it easy $27K.

    "And why are you insisting on a 'today only' attitude?"

    Because it is TODAY and if I wanted to purchase a new vehicle TODAY (not tomorrow, not at the end of the year)...this is what I'm looking at.

    " Supply will eventually catch up with demand."

    But so far...it hasn't.
  • ruking1ruking1 Member Posts: 19,826
    "I have the extended 100,000 mile warranty over and above the hybrid warranty (paid $987 for POM)."

    The good news and the bad news is that one would hope that one is able to fulfill on the 100 k warranty!!! While I am not familiar with how this extended warranty works in the real world and in your future, I can almost tell you that every time I have been faced with the numbers, buying an extended warranty did not make sense.

    This does not even take into consideration the fine print; which if you read it carefully, almost excludes EVERYTHING!! :(

    So for example, if your extended warranty pays for a min of 3920 (battery replacement) then you are in effect prepaying 987 for a 3920 future bill. BUT if it does not cover it, instead of 3920 (and assuming the Prius is as reliable as the old Toyota reputation) then you will be paying an extra 987. This of course will raise the per mile cost from .026133 cents to .0327133 or 20%.

    "OMG.. that is SO LAST CENTURY"

    Like wow, like this comment is like SOOO Brintey Spears!!

    Anyway now that we are beyond that, NAV units...I have had them (in an S4), have never had a need to use it. I plan my trips before I go, and if I don't..well...."Getting there is half the adventure" as the old AD slogan goes. I enjoy driving, driving is one of my passions, whether it be on the track or a leisurely Sunday drive. I don't just drive my cars to get from one place to the other, I drive them because I want to.

    It's like Bluetooth, I don't need it, don't care about how my cell phone operates in my car. When I'm in my car I usually want to be left alone from the office or whomever it might be. If I'm by myself and my wife calls, then I can take the time to put the phone to my ear, but if it is anyone other than family and it is not an emergency, they can wait until I'm to my destination. I'm in my friggin' car not the office.

    I don't need gee whiz components in my car than can break and become useless unless I shell out more $$ to fix them.

    I said before, all drivers are different, if you NEED toys, then fine, thats you, but please don't tell me to "Get real..." and that I will "wonder how (I) lived without it", you know nothing about me. I said I have no use for NAV and you should take it at that. I then went on to qualify that statement with "personal preference" meaning that if you wanted/needed "toys" then I thought it was fine...but I don't need/want those "toys".

    "NAV units will be offered in most cars within ten years"

    That's fine, but I won't pay extra for it. If it is a standard option on a vehicle I am looking at, then there is nothing I can do about it (sort of like the Sunroof on my GLS TDI, I don't need/want/use a sunroof, but to get leather I had to get a GLS in which the sunroof is standard). But I will not seek out NAV and pay extra for the option. That's just me...and if I'm SO LAST CENTURY...then so be it.

    > if I wanted to purchase a new vehicle TODAY (not tomorrow, not at the end of the year)

    That very reason makes your intentions insincere. (Sorry, but it's true.)

    The backorder list extends to about a 9-month delivery wait.

    You could *NOT* buy a new Prius *TODAY* even if you wanted to.

    > But so far

    Impatience is just plain wrong. October to June is only 8 months. Other vehicles have had much longer supply delays. Why isn't Prius considered the same as them? After all, the other vehicles didn't even have to deal with third-party suppliers to the degree Prius does (hint: battery-pack modules).

    JOHN
  • john1701ajohn1701a Member Posts: 1,897
    Have you ever noticed how MPG and the price of a gallon of gas are rarely disclosed?

    Not knowing how the numbers were calculated is a simple way to mislead. And if you really want to be deceptive, all you have to do is trick people into thinking that price for gas will be the same for the entire duration.

    Expecting it to not cost more 8 years from now is totally unrealistic. Consumption is growing rapidly worldwide, especially in the still-developing countries. And with refinery capacity already at maximum, the only way to increase is to build new ones... which hasn't happened for decades in the United States (we've been limited to the same 150 for quite some time now).

    The higher the price-per-gallon, the lower the cost-per-mile for a hybrid. (Those against hybrids don't want you to know just how much favor swings for hybrids after a certain threshold is exceeded.)

    And of course, how representative of real-world the MPG they select for the calculations is always a subject of refute.

  • pusterracingpusterracing Member Posts: 186
    The difference is John, I considered the Prius when I bought the TDI, BUT...I had to wait for the Prius and the TDI was on the lot. Also, the TDI was and is better bang for the buck.

    So, if I wanted a new car TODAY...I could go get one...a TDI...right off the lot....no waiting.
  • djasonwdjasonw Member Posts: 624
    Like I have been saying ALL along, the TDI is a good alternative for SOME people. People who are overly protective of their planet do NOT buy TDIs because of all the EXTRA crap that comes out of the tailpipe. To those folks, there are alternatives that make much more sense than the Prius. My brother just bought a Solara and averaged 32 MPG going 70-75 all the way back from Florida to NY. He paid under 20k and it's a real nice car. Don't forget folks, you can't buy a TDI in NY an CA. that's a great deal of the US population that needs other alternatives.
  • gagricegagrice Member Posts: 31,450
    I have a question. Is the 150k mile 8 year warranty for the whole US? If so what happens if none of the cells have failed at 8 years, then in the 9th year they start dying one at a time? That is a more realistic way to look at battery strings. I doubt if one cell goes bad during warranty that Toyota in their goodness will replace the whole battery string. Probably the one failed cell. Then you are messing around losing one cell at a time. Will one cell make any difference in the operation of the car? Can you make 35 miles to the Toyota dealer with a couple dead cells?
  • djasonwdjasonw Member Posts: 624
    The pack won't fail at one time. Even if it did, you still have your engine to rely on. Just as if the turbo died in a TDI, you'd still be able to drive it. I expect that with all the hybrids Toyota is bringing to market, expect battery/cell replacement to be VERY affordable.

    Toyota will also be producing and selling transaxle, inverter, battery, and control unit to Nissan for Altima Hybrid.

    "People who are overly protective of their planet do NOT buy TDIs because of all the EXTRA crap that comes out of the tailpipe."

    I own a farm, grow and eat organic food, use a front-loading water-conserving washing machine, etc. But I would buy a TDI, with eyes wide open to the particulate and NOx emissions issues. In a few years, I'd expect to be driving that vehicle on low-sulphur diesel in a 20% or richer biodiesel blend. At that point, its emissions should compare relatively well to the hybrids'. Its CO2 emission levels already are good, and its fuel economy in real world highway driving appears to EXCEED the hybrids'. Plus, I can get a Jetta TDI in a wagon, without a months-long wait for delivery. I don't want to wait until 2006 for clean diesel, and in other respects the TDI seems to be a good choice for me now. For urban sedan drivers, a hyrid might be better.

    "I've said it elsewhere: hybrid electric is a great technology, but so far appears to shine best in lightweight vehicles, in stop-and-go traffic."

    Toyota Prius weights 2,890 lbs, close to Camry and other mid-size cars. They are not light weight at all. Performance hybrids like RX400h will have more power to weight ratio, meaning drivetrain components will be more than twice powerful than Prius but the SUV weights less than twice of Prius.

    Hybrids shines best in stop-n-go traffic because they can take advantage of regenerative braking. Traditional ICE only cars are more efficient on highway than in the city. That does not mean that hybrids are inefficient on the highway! HSD is about 40% more efficient than ICE only car on highway. It drives me nuts when people say that HSD is inefficient on the highway while ignoring and comparing it to traditional car's already efficient highway mileage.

    "For the many Americans who drive heavier vehicles in mostly highway or suburban driving, .... and greater longevity, ..."

    The statement assumed that HSD use the same battery recharge cycle behavior on the highway as the city. On the highway, HSD does not recharge battery as often as in the city, especially while cruising at a constant speed! Let's look at the worst case city driving for the battery recharge cycle of the classic Prius:

    "Some critics have questioned whether hybrids will be durable over the long run. Perhaps they should ask Vancouver BC's Andrew Grant, the world's first Toyota Prius taxi cab driver. After three years of daily use his Prius had logged over 180,000 miles with only a handful of minor problems"

    http://cars.about.com/cs/familysedans/a/hybrid_explain.htm

    "a modern diesel engine may well deliver greater fuel economy improvements "

    HSD is more efficient than the most efficient or cleanest comparable diesel engine on the market and the winner of Best Fuel Economy International Engine of 2004.

    http://www.ukintpress.com/engineoftheyear/winners/bestfuel.html

    "in a system(diesel) that is less complex(than HSD) and therefore simpler to maintain"

    Modern diesel engines are much more complex with computer controlled 23,000 psi direct injection. If you look at the whole car, there is also a complex transmission and complex/expensive after-treatment emission filter with catalyst converter just to be allowed on the road and to be sold legally. And then you'll have to replace them as they also "wear" out.

    HSD is mechanically more simple and the complexity is migrated to the "computerization" of a modern car. The winner of Best New Engine of 2004.

    P.S: HSD won so many other awards and I can list them if anyone want to see more.

    > In a few years, I'd expect to be driving that vehicle on low-sulphur diesel in a 20% or richer biodiesel blend. At that point, its emissions should compare relatively well to the hybrids'.

    They will get WORSE, not better.

    We already pointed out that EPA report that clearly stated NOx (smog) emissions will increase with the use of biodiesel.

    > and its fuel economy in real world highway driving appears to EXCEED the hybrids'

    Feeding this misconception is not a good idea.

    A Jetta TDI vehicle that "doesn't require shifting" gets slightly lower than a equally sized HSD vehicle, like Prius.

    So whenever someone tries to generically use the term "hybrid" and not mention they are comparing to a manual, we are going to point out the misleading comment. Please be more specific next time.

    > For urban sedan drivers, a hyrid might be better.

    What does "urban" mean?

    We have already pointed out that "suburban" driving produces the greater efficiency using HSD, and that type isn't usually considered "city".

    "Because it is TODAY and if I wanted to purchase a new vehicle TODAY (not tomorrow, not at the end of the year)...this is what I'm looking at."

    There are specific vehicle vs. vehicle boards out there. This board is a general technology vs. technology board which involve discussion of the outlook of both technologies. LSD won't be available in US until 2006 but HSD hybrids are!

    "trick people into thinking that price for gas will be the same for the entire duration."

    Actually it is not the price of the fuel that we estimate to remain the same, but the DIFFERENCE in price between regular unleaded and diesel. Trends show that diesel usually runs $0.20 (on average) cheaper than gasoline. It was that way 20 years ago, 10 years ago and now...although prices have risen in the past 20 years.

    I agree...and I am not talking about LSD...read my previous posts. I am talking the technology that is available TODAY not 2 years from now...not 6 years from now.

    Will one cell make any difference in the operation of the car?

    No, that time has already been proven too.

    > Can you make 35 miles to the Toyota dealer with a couple dead cells?

    Yes, in fact you could likely make another 35,000 miles that way.

    An owner had an after-market stereo system added. The bonehead installer secured the amp by drilling holes through the protective metal casing of the battery-pack and ended up piercing 2 of the modules.

    The Prius drove perfectly, despite being injured. But since virtually all of the electricity for steep hill climbing comes from the engine, rather than the battery-pack, you wouldn't expect to notice anyway. Heck, most of my highway merging is done without ever tapping the battery-pack too.

    In fact, the owner would not have even known that had happened if it wasn't for the computer sending out a warning message stating it had detected module failures.

    HSD was designed to ignore dead modules. And since the electricity is mostly for efficiency sake, not power, the battery-pack can be crippled pretty bad without the need for concern. MPG will just drop, that's basically it. The vehicle will continue to run fine.

    "If so what happens if none of the cells have failed at 8 years, then in the 9th year they start dying one at a time?"

    It is a possibility but not likely. Even then, Prius has ability to generate electricity and drive the car since it has two electric motors.

    "Will one cell make any difference in the operation of the car? Can you make 35 miles to the Toyota dealer with a couple dead cells?"

    One cell will not make a difference in a normal driving condition as you are not requesting for maximum current from the battery. Technically you can make 35 miles trip to the dealer because Prius can generate electricity while accelerating. I don't know if the computer will let you drive when it detect that the pack is not working though. You are going to ask someone that experienced that.
