I am thinking about buying a Prius.

I know that it doesn't pencil out dollarwise, but it would be nice to be
able to use the carpool lane (I am in CA).

Anyone want to save me from bad decision?

Another question:  Are HID headlights worth it the bux, compared to
modern halogens?  I am middle aged and would like to be able to see
better at night.

Nope!

Looks to me as though you've already made a decision - even though, by your
own admission, the math doesn't work - and are simply seeking affirmation
to your flawed, twisted, "carpool lane" logic..........

.....that, or some sort of imaginary scapegoat which will allow you to say,
"Some idiot on the Internet said it was a good car....."

....when you know from what has already been published, and you have
already read, that they are NOT good cars, nor are they a good buy....HOV
lanes notwithstanding.

Not to me they're not - since my experience with them is usually on the
receiving end of a pair that have not been correctly aimed by their idiot
owners......especially the ones that have been installed upside-down by the
IO, blinding you with high-beam-aim while on low-beam.

I can state without fear of contradiction that HID headlights actually make
it *harder* for my own personal set of middle-aged eyes to see at
night.........

Forget what the sticker on the car says about its mileage.  The average
seems to be 43 to 48 mpg, with much depending on the gas quality such as
winter verses summer mixes (higher ethanol in winter makes their mileage
drop around 10% to the 43 mpg figures).  The fuel mixtures seem to differ by
states as well which accounts for much of the discrepancy in the car's mpg
figures.

About their durability, seems the Canadian taxi cab companies are moving to
them as they did save their companies hundreds of dollars (monthly!) in
maintenance and fuel costs.  One driver logged over 200,000 miles in year
with virtually no problems.  Warranty for the battery is moot since, in
California, the warranty is something like 10 years or 120,000 miles since
they determine it as part of the emission control system.  The change from
ICE (Internal Combustion Engine) to HV motor is indistinguishable while
driving and can happen literally hundreds of times just on the way to work.
No shifting either. System is very well thought out.  Oh, all driver
controls such as the steering wheel, gas pedal, and even brake pedal are
fly-by-wire controls. Majority of braking is by the HV motor.  Pretty
ingenious in that the fly-by-wire brake pedal tells the computer the amount
of deceleration needed and feeds the ECM info to the electric motor to allow
the deceleration force.  The final 5-7 mph is by the electrically-assisted
hydraulic brakes which should allow for longer brake pad service life.

The HOV issue.  This is only good for up to the year 2008, beyond that who
knows?  Also, some county highways (not federal or state) with the HOV lanes
forbid the Prius with solo driver on them even with the $8 sticker.  Note,
too, that there is a set number of stickers available (California set the
number at 75,000) so the longer you wait, who knows if you'll get one?

The feature list on the vehicle is great with their integrated Bluetooth
phone system and GPS navigational system which will boost the car's base
price by $6K.  Their Smart Key system cannot be beat, which makes it a very
difficult car to steal short of a flat-bed hauler.  Just don't lose a key
fob else it will cost you dearly.  The new '06 models added leather seats
and a rearview camera integrated into the NAV console.  The non-US models
have auto parallel parking as well (part of the fly-by-wire capabilities).
There is a demo, in Japanese however, on the web of it in action.

Their HID lights are auto-leveling based on the sensor on the rear axle, if
that were what its called, unit.  They seem to gain brightness in a few
seconds of turning on, maybe to save the lamps from voltage surge?  They
will shut off automatically when the driver's door opens.  They have that
familiar bluish tint.

A buyer's warning would be the surcharges various dealers are charging which
range from MSRP to $6000 over, and the highest seem to be in the Los Angeles
area.  One advantage, if you call it that, is that the resale value has been
high, much as was/is the state of Harley-Davidson motorcycles in the resale
market.  The wait times can be excessive though.

I'd check out the Prius forums for more facts like Priuschat.com or
Priusonline.com.  Good luck.

Miles or kilometers?

I can distinguish it.

There is a difference between steer-by-wire and electric power assist.
The Prius has the later.

The real benefit here is the regenerative current to the HV battery.
The HV motors are "instructed" to become generators during braking and
save the IC engine (and gasoline) from performing this task.  As a
bonus, brake pads could conceivably last the life of the car with
mostly highway driving.

Grand, but that tells us nothing about the long-term durability of the
traction battery in terms of *age*. My officemate just had to have a new
traction battery in his '03 Honda Civic hybrid.

Why do you think it might be a bad decision? Even if you break even or
less, you are doing your part to fight against high petroleum prices and
cut down the emission of greenhouse gases.  When my current car needs
replacement I am very seriously considering a Prius.  Of all the hybrids
I currently see on the market, I think Toyota has done the best job of
engineering the Prius.

My son recently bought a Honda hybrid for himself, the Insight (sp?) maybe.
He claims to have gotten an indicated mileage, more or less checked with
GPS,
in excess of 80 mpg.

His wife already has the large Honda hybrid, and it is a very smooth and
nice
car.  She typically gets in the range of 48 mpg, maybe more if her foot is
sore.

The HOV lane seems to have been an attraction in their case too.

In the long run, I would expect the maintenance costs to overwhelm the gas
savings, but time will tell.

You may be fighting against high petroleum prices...but hybrids at this
point still do not make economical sense for the consumer OR the
economy, they are subsidized by the government so that Toyota does not
lose money on them. It costs Toyota more than the $20k to manufacture
the car, but the government eats the rest. Not a good thing. The added
complexity of the hybrid components also mean that theres more stuff to
break.

And I dont know if it's just me...but I feel safer with a mechanical
link between the brake pedal and the brakes than "brake-by-wire". Just
my two cents.

If you want to save fuel economically, get a Civic HX (36/44 mpg) or a
turbodiesel.

What current production vehicle has a true "mechanical" connection
between the brake pedal and the brakes? The hydraulic connection is not
really what I would consider a "mechanical" link. That is why you have
the cable operated parking / E-brake as backup. If the "brake-by-wire"
system also has the cable parking / E-brake it's pretty comparable.

Isn't the Prius a dual brake system?  Doesn't the use of brake engage
"generator" mode but also apply hydraulic pressure to regular brakes? If
generator mode fails, don't you STILL have regular hydraulic + friction
brakes?

I don't know. I don't have a Prius and have no intention of purchasing
one.

If it applies "real" brakes at the same time with the MG mode, then it
is throwing away potentially recoverable energy as heat in the brakes.

The hybrid setup really produces a false economy by using an under
powered gas engine and forcing drivers to adopt a different driving
style. The electric motor is supposed to help the under powered gas
engine get the vehicle going using energy recovered from braking.

If you have been a good driver on a conventional vehicle and learned to
watch the traffic ahead and let compression braking do the majority of
your braking thereby minimizing the use of the service brakes and make
modest acceleration when traffic starts then there will be minimal
energy available to be recovered from braking and little advantage to
the electric boost on startup and you will will little benefit from a
hybrid system. You will also have seen optimal mileage from your
conventional vehicle, making the hybrid appear to be an even worse
value.

Those who race up to stopped traffic before slamming on the brakes and
floor it when traffic starts will of course will have experienced
terrible mileage on a conventional vehicle and will also see the most
apparent benefit from a hybrid system as there will be significant
energy to recover from braking and significant need for the electric
boost on startup.

I strongly suggest you do some googling on "volumetric
efficiency" and "pumping losses" so you can understand
the misunderstanding you have about smaller engines as
used in hybrids. Also, look up "regenerative braking".

Hybrids get better mileage, that's a fact. It's hard to
fake using less gas to drive longer distances, LOL!

I'm well aware of those things, but my points still stand.

Hybrids get better mileage on the surface, but it comes from far less
capability and forcing different driving styles in large part. A
comparable weight conventional vehicle with an appropriately sized
engine, driven in a fuel conscious manner will get quite similar
mileage.

Not so in my experience.  My older car had roughly the same size engine as
the Prius but the mpg difference is greater.  Old Saturn gave me around 27
mpg; Prius is delivering 43 mpg now in the winter (was 47 mpg in summer with
less ethanol to mix).  The efficiency of the old dinosaur engine was around
18% and mostly due to friction losses.  I still drive with a lead foot
although I'm now in the "Trying to raise my mpg game" mode.

The coupling of the electric motor with its greater efficiency (lower
frictional loss) with that of the less efficient gas engine has raised that
older dinosaur engine efficiency of 18% to something far greater, plus the
lack of idling fuel losses and richer warm-up losses (the Prius has a
hot-water thermos that holds the engine heat for approximately 3 days and
pumps in back into the cold engine at startup).  These are not directly
controlled by the driver's abilities between a older engine design and a
hybrid.  It's more of a maximizing of losses that were present in the older
vehicle designs.

Your experience supports my points as explained below.

> I still drive with a lead foot
> although I'm now in the "Trying to raise my mpg game" mode.

This is exactly why you see a difference as I noted in a previous post.
The hybrid systems main benefit is that it helps to cover bad driving
style, not that it significantly raises efficiency under good driving
style.

If you were to try driving both vehicle using a fuel conscious driving
style i.e. using compression braking well before stopped traffic to
minimize braking, and making more gentle starts you would see the MPG
gap narrow considerably. Try the same comparison using a current
comparable conventional car and the MPG gap would be even smaller due to
the efficiency gains in the gas engine over those from a few years back.

Without what is essentially "bad" driving style, the hybrid system has
significantly fewer opportunities to add energy o the batteries and
significantly less need to the electric boost at startup. What energy it
is able to recover and reuse during light load driving is largely offset
by the extra weight of the battery pack and reduced capacity compared to
the small conventional car.

> The coupling of the electric motor with its greater efficiency (lower
> frictional loss)

The electric motor itself has lower friction losses (only a couple
friction points), but the generator mode efficiency and battery charging
losses need to be factored in along with the resistive losses in the MG
controller making the overall electric MG system efficiency considerably
less than the motor efficiency would imply.

The last few points you make, idling losses and warm-up losses are both
technologies that can and have been applied to conventional systems as
well and are not really part of the hybrid system which I have been
referring to. If you applied them to a conventional small car and
compared the MPG to a hybrid under fuel conscious driving style the MPG
difference would all but disappear and you would still have the reduced
capacity on the hybrid.

The bottom line is that absent bad driving style and when taking all the
factors into account, the hybrid systems produce far less of an increase
in efficiency than they MPG numbers and hype would imply.

A properly designed hybrid should not require any change in driving
style.  There is a big disparity in normal autos between the peak hp
required and the average. In a proper hybrid the IC engine should be
sized for the average power required, the electric should make up the
difference between the average and peak.  Result should be same performance.

BTW, driving style has a lot to do with milage obtained in a
conventional car.  People were screaming about price of gas last month,
but no one seemed to drive any differently.  No one slowed down to speed
limits, and so many folks seem to prefer to drive right up to a red
light and brake heavily, rather than coast up to (or through light when
it does change green. I'd love to have a buck for every guy who zoomed
around me when I backed off and coasted, then cut back in front of me to
stop at light. I'd approach the light at 20 or 30 mph, but had to almost
stop 'cause that guy was starting from a dead stop and making me almost
stop too.  :-(  What is the big advantage about getting to the light in
time to sit there for ten seconds, then start from a dead stop?

Good in theory, and works well on the new diesel-electric yard engines
in rail yards, but doesn't translate well into a consumer auto.

Which is exactly what I mentioned, that the hybrids derive much of their
apparent economy by compensating for bad driving style, not from true
efficiency.

I've been driving my truck in the fuel economy style for years and I'm
quite sure I'd get much worse MPG if I drove using the gas pedal as an
on-off switch like some people do.

Ah!  I think maybe you do not understand hybrid theory.  The electric
drive Diesel is NOT like a hybrid car.  The locomotive has no STORAGE
capability.  So the Diesel IC component must be sized for the PEAK HP
requirement. If there were no storage battery, the hybrid car would
indeed be limited in performance to size of the IC engine, but the
storage battery provides this 'load leveling'.

The steam cars were the same way.  The limiting HP was the boiler HP,
not the engine HP, which was often well above capability of the boiler.
 The steam race cars had phenomenal performance in short races, but
would "run out of steam" in longer events.  But then, I race car has a
duty cycle where the average power required is much closer to peak
requirement than for normal passenger car driving.  Yeah, a hybrid would
not be able to cruise Autobahn at 100+ speeds for long distances, but
for US driving it is okay.

I think you've missed the latest developments in locomotive technology.
I specified the new *yard* engines, the ones that only do switcher duty
in rail yards. These engines normally run 24 hours a day, idling a good
60% of the time.

There is a new breed of them that have smaller diesel gensets and do
indeed have a battery bank. The genset is sized for about 50% of the
necessary capacity so that it charges the batteries during that 60% idle
time which results in the same performance for the intermittent yard
duty, with much less fuel consumption and emissions.

This technology does not work for regular long haul engines, at least
not yet, because they do not have enough idle time to recharge.

The current generation of hybrids are really only of any use in mostly
city driving. Outside the city they don't perform very well.

Good thing that the vast majority of the population lives
inside urban and surburban (read "city) areas, eh? Of course,
a hybrid would be unable to use it's advantages in a long
drive across Kansas flatland, but then again a combine would
be completely useless in urban Los Angeles.   :)

Regenerative braking plus being able to use the engine's
powerband more efficiently are the key to hybrids getting
better gas mileage. That's basic physics, provable fact.

BTW, locomotives are pretty much useless on American inner
city freeways as well. LOL!

Dunno, perhaps it could help flatten that wasteland.

CVTs use the engines power band more effectively and are far less
complex and expensive than the hybrid systems. With proper driving
technique there is little braking to regen from as well.

That must be why there are commuter rail lines down the middle of most

Well, I don't own a Prius, and magazine road tests these days seldom
test for top speed.  Okay, you Prius owners, how fast have you driven
your cars on the highway?

As previously posted regarding regen braking:
The real benefit here is the regenerative current to the HV battery.
The HV motors are "instructed" to become generators during braking and
save the IC engine (and gasoline) from performing this task (of keeping
the
HV battery charged).  As a bonus, brake pads could conceivably last the
life
of the car with mostly highway driving.

What this means is that the energy that is absorbed by the MGs on
deceleration accounts for a great deal of your braking in the Prius and
other hybrids.  The brake system *is* brake-by-wire, but with quite a
bit of backup measure built in, including a massive capacitor pack
incase of electrical failure.  The actual disc brake system can stop
the car just as hard as any other vehicle's system, but it is regulated
to assist the regenerative braking and therefore offers much longer pad
life.

I agree.  The OP may be thinking tax credits for buying alternative
fuel vehicles somehow flow to the car maker.  Of course they don't,
although they do create an artificial demand for hybrids by lowering
the price for consumers.

I had heard that the US government subsidized all hybrid vehicles to get
them into the market early, before they could be self-sustained. What I
was talking about was independant of the tax credits. I can't verify it
though, i heard it a while back.

Though there may be a tax credit for buying a hybrid, similar
to the various tax credits many others get for various reasons
including the oil industry that gets billions, most people who
buy a hybrid do so for the principle and could easily afford
a similarly priced non-hybrid car from other makers, or even
more expensive models of cars and trucks. I can see the makers
selling the hybrid with a reduced profit margin, that could
be called a subsidy I guess, but the benefit to the maker is
better PR plus actual experience building and maintaining a
fleet of hybrids. In the long term that experience will pay
off, just like the experience with computerized injection has
paid off.

Any makers that aren't aggressively developing hybrid and
EV platforms will soon find themselves sinking in the slow
lane, yet again.

Since they WERE the ONLY one that engineered the Prius...  no doubt
they did the best job.

I had a Prius and got rid of it because I drove just 8,000 miles a
year.  I traded it with someone who drove over 36,000/year was getting
killed on gas.  But I liked the Prius a lot, and I don't think it's an
unreasonable choice if you need a hatchback, even if you don't drive
enough to justify its extra cost (about 35,000+/year).  The best 4-door
hatch seems to be the Mazda 3.  I'm disappointed with the Matrix
because it's such a gas hog.

HIDs are a waste because it's incredibly expensive to replace the
assemblies, which are also favorites among thieves (you may want to ask
your insurer what HIDs cost to cover).  Just get brighter conventional
lamps.

You will pay a premium over a comparably sized full gasoline engine
car.  A Corolla will easily get in the high 30's mpg, so it is
difficult to justify paying a premium for a Prius that will get even
better milage.  It will take several years of driving the Prius to
generate enough savings in gasoline to offset it's higher initial
price.

I think these cars are too new to know what the long term maintenance
costs will be.  That battery pack will eventually have to be replaced,
and the car uses some sophisticated (read expensive) systems to switch
between power plants.

> Anyone want to save me from bad decision?

Sure.  I was amazed at the number of people that paniced when gas hit
$3.00 a gallon this year.  They were literally standing in line at the
Toyota and Honda dealerships begging for soemone to take deposit money
and be put on the waiting list.

Try driving the car.  On my Volvo the HID lights provide excellent low
beam lighting for in-town driving.  On the road high beams do not put
out nearly as much light as a standard halogen system.  Consequently
objects down the road are dimly lit at best.   And HID lights have a
very sharp lighting cutoff that makes driving in hilly country a
challenge - the road ahead will suddenly disappears into darkness.

The time and aggravation saved by being allowed to solo in the carpool
lane seems to be a big factor among the Prius owners of my
acquaintance.  Back to the cash basis, some of them might also save a
few dollars per workday in bridge tolls, as some areas reduce or
eliminate tolls for certain vehicles that have hybrid power, run on
alternative fuels, or are otherwise distinguished in the mileage and/or
emissions departments.

These factors might be smaller or even irrelevant to other potential
buyers, even in the same urban area.  For sure, it is my highly
unscientific anecdotal impression that in cities without HOV lanes or
tolls to be exempt from, you just don't see as many hybrids.

Caveat lector:  Be sure of local laws before choosing a particular
model of hybrid or jumping into the car-pool lane all alone.  Different
states have different policies on who gets to do what and where!

......and, there is a movement on to start taxing ALL vehicles by the mile
(using a device that feeds your driving info directly to a government
agency) as opposed to fuel taxes. This was specifically targeted towards
the vehicles that use much less fuel - paying less taxes - yet still use
the roads much the same as a conventionally-fueled vehicle that pays fuel
tax.

I have read of more than one jurisdiction that is considering removing
the special treatment hybrid cars get in carpool lanes.  Allowing
single driver hybrids in carpool lanes defeats the purpose of those
lanes.

And defeats the purpose of even having a hybrid to begin with.  The reason
is to save fuel, but a conventional car that has 2 people saves more gas
than 2 hybrids each with 1 person.

Exactly.  For example the Toyota Corolla costs less, holds more and
gets milage that is only marginally poorer than the Prius.  I don't
understand it, but I do know the carpool lanes are jammed with cars
these days and there are more than a few single driver hybrids out
there.

Ahhh, if only it was possible for everyone to live their
life in pairs. In my case, nobody at works lives anywhere
near me, and I can't afford to live anywhere near any of
my workmates. Carpooling isn't an option for me. Also, FWIW
there are no carpool lanes anywhere near my normal driving
routes, so the only benefit a Prius offers is saving fuel,
plus the intangible but no less valuable benefit of being
able to stick it to OPEC.

There is the possibility that the rumor is true about states taxing
hybrid vehicles. I think it would be foolish for governments to
"punish" people who are taking initative to reduce emissions and fuel
consumption. If you take care of your car, it shoudl be cost effective.

I suspect you are referring to the tax-by-mile movement wherein ALL
vehicles using public highways would be taxed by the mile as opposed to the
amount of fuel used (fuel taxes).

I see this as a fair and equitable way to pay for highway maintenance by
ALL the vehicles that use the roads.

Now, if we can only get the bicyclists paying their fair share of road
taxes for using the roads - yet NOT necessarily following the rules of the
roads.

I do not see it as "fair and equitable" to have one's movements continuously
tracked by government via some kind of sputnik. No way would I install such
a gadget in my car, and I would hope most people in this country would have
enough sense to "just say no" to such a thing. (My vehicle gets about 14 mpg
so I'm already paying plenty of fuel taxes.)

I also see a lot of traffic lanes being changed to "Bike Only Lanes" where
some bicyclist group -  who pays no road tax -  lobby and, subsequently,
make the surface streets downtown become a gridlock due to one traffic lane
being squeezed out for two opposing-flow bicyclist lanes (of which I rarely
see one using "The Lane").  Then they argue for better street cleaning to
prevent a flat from a goats-head sticker.  All tax free for the bicyclist.

Tax the damn bicyclist as well since they also use the crumbling roadways
and pay no tax on the asphalt they use.

Taxing a hybrid because it uses less fuel makes conservation a joke.

I have no interest in hybrids.  If someone else wants to buy into those
pregnant roller skates and their Rube Goldberg drivetrains that's entirely
their business.

First thing that needs to be done is to weed out corruption and pork
to reduce road maintenance costs. (Though I would not hold my breath
waiting for that one.) Then raise the gas tax enough to cover the
remaining shortfall.

I would much rather pay a little more for gas than put up with the kind
of massive and continual invasion of privacy that is being proposed as
an alternative.

No it ain't because heavier vehicles (SUV's vans, big trucks, etc.) wear the
road surface more than lightweight vehicles.  To make a per-mile tax fair
you need to also change the tax rate for heavier vehicles.

In any case, semi-trucks put hundreds the amount of wear on the roads
that a car does but do not pay higher taxes in proportion to the amount of
damage they do to the road.  So to make a per-mile tax fair you need to
take on the trucking lobby and raise taxes on trucks because what is
going on now amounts to a subsidy of the trucking industry by the
rest of the vehicles on the road.

That would be silly (though of course many silly things advance into
law, or regulation that has the force of law, if citizens don't stay
alert -- not to mention laws and rules that make sense within their
context but might not get examined from a wider perspective and tested
against strategic goals).

Hybrid cars that I'm familiar with run on gasoline or other taxable
fuels at all times -- they just aren't necessarily burning it at any
given moment.  Electric cars are the ones that don't feed fuel taxes
into that revenue stream -- that, and cars running on ersatz or
homemade fuels.

Pending the development of a remarkably better battery technology,
though, pure electrics seem to be in the deep shadows of other
technologies, and it's hard for me to get too worked up about the
handful of people willing to dive restaurant dumpsters and cook up
biodiesel in their toolshed...

Of course, if the mainstream fleet, powered by taxed motor fuels,
achieved remarkably
better mileage, there would be a reduction in taxes, but we should have
such problems!

As for congestion, I don't know about all states, but if memory serves,
California built in escape clause  (no pun intended and probably not
much of one achieved) allowing them to withdraw HOV-lane exemptions for
such vehicles if the carpool lane turns into a single-passenger morass
of hybrids and alt-fuel vehicles.    Some or all states also take it
upon themselves to define the exempt models -- hybrids that don't meet
emissions or mileage goals, which would mostly be big'uns,  might not
get the magic sticker.

Last time I checked, there was also an unresolved state-vs.-Federal
sitzkreig on the whole subject of whether allowing HOV lane exemptions
for gasoline powered hybrids of any sort ought to be at the discretion
of the states (the Federal authorities wanted to restrict it to truly
alternative-fuel or zero-emissions vehicles).

The halogen lamps in the Prius are well designed, but if nighttime vision
is important to you, then get the HIDs. On that particular car, they are
also a well-designed unit and give better performance than the halogen
lamps. The "target of thieves" comment applies primarily to people who buy
cars made by Nissan.

Since using the carpool lane is your only stated requirement, all you
need is a small motorcycle or a large scooter - cost is about $3k -
$6k. They will give even better mileage than a Prius.

Not in my experience.  My Prius gets better mileage than any motorcycle I've
owned (and still do) with an engine sufficient to drive on the freeway.

The Honda Rebel 250cc is freeway legal, and seems to get about 70mpg
per http://www.epinions.com/content_180679249540, which is slightly
better than the Prius.

The Bajaj Chetak (http://www.bajajusa.com/scooters.htm) is
*technically* freeway legal, and gets 110mpg, although I would not want
to drive the California freeways on a 150. A 250 like the Honda would
be much better for keeping up with traffic.

Not to mention windshield wipers, a heater and A/C system,
room for groceries and/or passengers, a trunk, spare tire
and jack, and crash protection.

Of course, running a sportbike through the twisties has
a superior element of fun than a Prius.   :)

How true.

As Mack mentioned earlier in the thread, my bikes don't get as good of
mileage either.  The H-D R.K. gets about 38 mpg and the BMW gets about same
to maybe 40 mpg on the highway.  Our Prius gets around 45mpg on the highway.
Dunno, but it sure is odd the car gets better mpg's - and it has a larger
engine than either of the two-cylinder bikes do.  If I also factor in
maintenance costs of the bikes over that of the car, the car (er, Prius)
wins hands down (damn motorcycle tires are expensive and just don't last for
me, maybe 1/5 the mileage of a car tire - not to mention the cost$ of BMW
bike service$!).
