This is the basis of the TD version the economy claims stem from. this wiould be the 'lupo 3l' - and the link i gave a few days ago in the thread about the canadian test, right? Few things to remember. No PS - normal, its so small you don't need it. Don't need it in my 88 civic either. AC is not standard in european cars, its a hgih-equipment spec standard, or otherwise option. Most of europe you don't need it. the engine stop+start is something common to a fair few of the 'high effiiciency cars' The Rock bottom comfort - well thats an american reviewing a european only claim. Used to luxury boats, that get terribale millage, and well hes not in one, plus it was a pre-producton model. By contrst, the BBC's top reviewer (and one of the most influential reviewers in europe) tested the F150 recently. Thats the best selling vehicle in the US, and he tested a production model (the lightning in fact) and he said pretty much the same thing about the comforts, and the production quality. He liked the engine, but then, since he was about to take delivery of the new FordGT (which has the same engine0 i'm not surprised there. In short, i feel the usatoday reviewer was predjudiced by his american car standards, same as europeans are predjudiced against american vehicles (such as their amazement when they drove the caddie CTS, branding it 'the first american car to be able to handle a corner', so which I say "its about time"

OMG - I wasn't familiar with the Lupo, so I did a little research. See http://www.usatoday.com/money/consumer/autos/mareview/mauto497.htm for the USA Today report on an early test version. The truth is ugly indeed! Non-existent acceleration, maddening transmission behavior, rock-bottom comfort, and so much more. Talk about doing tricks to get fuel economy - this benighted little gremlin tries them all. No A/C of course, no P/S available, and a $3000 premium for the privilege of being abused by your car. This is the basis of the TD version the economy claims stem from.

>>>>>>> Here is what Toyota has to say about battery replacement >>>>>>> and recycling: [quoted text clipped - 48 lines] >rechargable battery could last longer than a couple years... just as we >might watch sprinters and conclude no human can run more than a mile. oh dear, the old 'we're all familier with X, which is kinda like Y, and so what we know happens with X, we also assume happens to y - Sorry, thats complete and utter, unadulterated BULLSHIT. Save your pop-psychology for the easily impressed - such as any children under 10 you might have.
NIcads and NIMH have lmited charge cycles. Why? conductive crystaline formaton int he cell, producing an effectively 'shorter' cell. can you fix this? yes you can, alsthough its tricky to do, and risky - you zap the cells.
>When it comes down to it, the experiment is on the roads and has been >successful for 7 years. At least one Prius has exceeded 200K miles >http://www.hybridexperience.ca/Reliability.htm Whoopdie do. One has managed 200k miles, conrgatulations, pat on the back there. I've a first gen caravan thats managed that too, doesn't make it a particularly good van. Second, you keep making this song and deal about a vehicle that is expensive to make, would have to be run for over 300,000 miles before its actually more efficient in TOTAL than a similarly sized conventional car, and which would probably be more efficient if you just ran it as a straight petrol engine. Want to be fuel efficient, two easy rules 1) be smooth with driving, and make speed ransitions smooth and slowly 2) remove any unneccesarry weight. - less weight = less fuel needed. Take out the weighty electrical system, and you'll probably get around the same mpg.
Lets look at it another way, EPA rating for prius 51mpg (very optomistic rating, as with all EPA ratings) I've seen an Audi A8 (thats the big one) with a 4l V8 twin turbo engine (thats a big engine too) return 40mpg. A car designed to be big, heavy, smooth, comfortable - ANYTHING but fuel efficient - can get such figures speaks volumes. i will admit that was highway driving, if you'd rather have a small car, and think about fuel economy from the get-go, VW group also make a lupo - agains non-hybrid - thats RATED at 65mpg.
People with hybrids can be described in one word - poser. "Look at me, i'm driving a hybrid, aren't I trendy, trying to show i'm conserned with the enviroment, but cool, and have money to waste" - what a right old load of bollocks it is.

>>>>>> Here is what Toyota has to say about battery replacement >>>>>> and recycling: [quoted text clipped - 23 lines] > They get charged before they run completely down;partial charges,"topping > off".They still are charge cycles. However, they are not failing. Try googling "prius battery fail" and you will see about 10K hits with a ton of speculation about when the battery will fail and about failures of the 12 volt aux battery (which is as vulnerable as the 12 volt battery in conventional cars)... but good luck finding a report of one that has actually died a natural death. Then google "acura transmission fail" and you will get about 22K hits; why the transmissions are failing, what to do about the transmissions failing. One member of the Yahoo Prius group just had his150K mile service done on his 2001 and has done nothing but scheduled maintenance and tire replacement - no battery failure yet. That figures since Toyota warranties the hybrid system, including battery, for 8 years/100K miles (150K miles in CA). Even the original Prius, sold since 1998 in Japan, has no battery failure issues.
There is nothing in chemistry that limits the number of charge cycles for a primary cell. Edison cells, for example, have no natural limitations on charge/discharge cycles and usually last for decades but have poor energy density. We are familiar with lead acid and NiCads which have serious life limitations because of their particular chemistry so we assume all rechargables do. Then we look at the batteries in portable electronics - they are designed to charge as quickly as possible, have the highest possible energy density and be profitable to replace - and we decide no rechargable battery could last longer than a couple years... just as we might watch sprinters and conclude no human can run more than a mile.
When it comes down to it, the experiment is on the roads and has been successful for 7 years. At least one Prius has exceeded 200K miles http://www.hybridexperience.ca/Reliability.htm

>>> Here is what Toyota has to say about battery replacement >>> and recycling: [quoted text clipped - 7 lines] > > Please enlighten us with your wisdom on the subject. NiMH and NiCd can only be recharged a number of times before their capacity drops off,and L-A batteries suffer from sulfation,electrolyte loss,and vibration/shock damage(material falls out of the lead grids,shorts the cell). Hot environments like the Southwest and Florida will shorten battery life further. I don't know of any rechargeable battery chemistry that can be recharged 100,000 times.

>The current edition of "Car and Driver" (magazine) has an interesting >article about the dark side of the hybrids on page 26. The date on the >cover is September 2005. Maybe the author of the article should have done a little actual research. Here is what Toyota has to say about battery replacement and recycling:
http://pressroom.toyota.com/photo_library/display_release.html?id=20040623
How long does the Prius battery last and what is the replacement cost?
The Prius battery (and the battery-power management system) has been designed to maximize battery life. In part this is done by keeping the battery at an optimum charge level - never fully draining it and never fully recharging it. As a result, the Prius battery leads a pretty easy life. We have lab data showing the equivalent of 180,000 miles with no deterioration and expect it to last the life of the vehicle. We also expect battery technology to continue to improve: the second-generation model battery is 15% smaller, 25% lighter, and has 35% more specific power than the first. This is true of price as well. Between the 2003 and 2004 models, service battery costs came down 36% and we expect them to continue to drop so that by the time replacements may be needed it won't be a much of an issue. Since the car went on sale in 2000, Toyota has not replaced a single battery for wear and tear.
Is there a recycling plan in place for nickel-metal hydride batteries?
Toyota has a comprehensive battery recycling program in place and has been recycling nickel-metal hydride batteries since the RAV4 Electric Vehicle was introduced in 1998. Every part of the battery, from the precious metals to the plastic, plates, steel case and the wiring, is recycled. To ensure that batteries come back to Toyota, each battery has a phone number on it to call for recycling information and dealers are paid a $200 "bounty" for each battery.

The current edition of "Car and Driver" (magazine) has an interesting article about the dark side of the hybrids on page 26. The date on the cover is September 2005.
Many of the so called "greenies" have purchased hybrids because they really care about the environment. I learned about something from the article that I had never thought about before. What's going to happen to those millions of batteries in hybrid vehicles after they wear out? They will be placed in landfills. Imagine the harm that those batteries may do to the enviroment after they are laying in a landfill for 50 years.
If you own or are planning to buy a hybrid vehicle, I advise you to read the article.
