Aaron - 03 Nov 2004 10:54 GMT
I just got a new job in Irvine and have a girlfriend in Pasadena. I
moved to Anaheim so that I'm not too far from both.

Since I will be doing a lot of commuting I thought a hybrid would be a
good option. I checked both the insight and prius and the prius looks
like the best option, especially for traffic.

My question is, would it be worth getting a prius to save gas money??
It looks better than a insight since it doesn't run the gas engine all
the time. I just don't want to waste my money buying a hybrid when I
can just buy another car that burns less fuel (like a civic) for less
money.

Thanks for any suggestions,
Aaron

If you're going to buy a new car anyway, then it's worth buying.  It
will cost you more than a conventional car, but you'll get a $2000 tax
exemption (not a tax credit, so the tax break is $2000 multiplied by
your tax bracket).  Eventually, you will save in gas expenditures the
difference in prices--the better mileage the other car gets, the longer
it will take to make up the difference, though.

But the reason to get a Prius is not to save money; it is to cut down on
emissions and to enjoy the high-tech features. :)

There are better placed to argue.  It doesn't matter if you are the 51%
majority or 48% minority.  You'll end up ignored if you pursue it here.

The reality is that he took only 51% of the popular vote; that is one of
the smallest margins ever.  The number of counties means bupkis.  (Yeah,
and so does the popular vote because of the Electoral College.  However,
the popular vote shows that he doesn't have much of a mandate.)

Yes, so the votes given to Bush in Ohio by Diebold is what gave Bush the
election, just like the Florida vote theft four years earlier gave it to
him then.

The current Prius just started its 2nd model year, with major changes
improvements in those areas.  I doubt that there will be any major
changes before the 2006 models.

The bottom line is that if you don't need a new car now and don't have a
strong want for one now, wait until you do.

It's a federal tax credit (not an exemption), and is applicable
throughout the country.

In 2006, it will be reduced to $500, and in 2007, it will be
eliminated--unless the law is changed again, that is.

Your dealer is just plain wrong.

To be more accurate, it is a tax deduction - you don't get $2000 back, but
you do get to deduct $2000 from your taxable income. Still very worthwhile.

Sorry, I got the terms wrong; I knew what it was, but used the wrong
term.  Actually, it's neither a credit, exemption, nor deduction; it's
an adjustment.  It is entered on line 35 of the (2003; the line number
may change for the 2004) tax return.

Credits:  Money reducing the tax itself.

Exemption:  Money reducing income, based on the number of people in the
family (who meet age and other criteria) and certain physical conditions
of the filer or filers (e.g., age and eyesight).

Deduction:  Money reducing income, based on expenditures for certain
activities (e.g., medical expenses, property tax, mortgage payments)
meeting specific criteria--or a standard amount, depending on filing
status (e.g., single, married, head of household)--whichever is greater.

Adjustment:  Money reducing income based upon expenditures for certain
listed activities, in addition to any exemptions or deductions.

The advantage of tax credits is that it reduces the tax
dollar-for-dollar by the amount you can claim.  All the rest reduce the
tax by the percentage of your tax bracket.  (E.g., a $100 deduction or
adjustment results in a $25 tax savings for someone in the 25$ tax
bracket.)

The advantage of adjustments is that you do not have to itemize to claim
it.  If your itemized deductions come to less than the standard
deduction, you have to take the standard deduction, but you can then
reduce your claimed income even further with any adjustments you may be
eligible for.

Right, Mike.  Even if one takes the standard deduction instead of itemizing,
they still benefit from the $2000.00 adjustment.

Your dealer is misinformed.

Thanks to the newly signed "Working Families Tax Relief Act of 2004,"
the Clean Fueled Vehicle deduction has been extended.  The amount of
the deduction for purchases in 2004 and 2005 are now the old amount of
$2000, whereas prior to the act the amounts were $1500 and $1000
respectively.  2006 is still $500, with the sunset still in 2007.

That's been changed by legislation passed last month.  It was restored
to $2000 this year (and next year).  In 2006, it becomes $500, and after
that it's eliminated--unless it's changed by legislation again.

If you want to minimize your direct expenses, buy a recent used Civic.  
If you want get a really neat car that reduces oil imports and minimizes

Austin and back, and most recently to Atlanta, Mobile, Lake Charles, LA, and
home again with flawless performance, significant velocity, and good

A very good question.  Because I was considering buying a Prius, I
made some energy calculations to get an idea of how much gasoline is
"recovered" through the "regenerative" braking.

The energy recovered from braking the car and subsequently storing it
in the battery is some fraction -- less than 1 -- of the kinetic
energy of the car.  For purposes of calculation I assumed 100% would
be recovered.  The kinetic energy depends on the mass and speed of the
car and is calculated from the familiar equation KE = 1/2 * m(v^2).
I used 2890 lbs for the weight of the car as given in the Prius
brochure  (mass = 2890/32.2 = 89.75 slugs).  The results at several
speeds are given below:

20 mph -   50 Btu
30 mph - 112 Btu
40 mph - 199 Btu
50 mph - 311 Btu
60 mph - 448 Btu

For illustration, let's assume that if the Prius went 45 miles with no
stops it would get 45 miles per gallon.

To estimate the effect of recovery by regenerative braking, assume
another trip of 45 miles with stops every mile from 30 mph.  That's a
total of 45 stops which would recover 5,040 Btu.  Gasoline has a heat
of combustion of approximately 115,000 Btu per gallon, thus the 5,040
recovered Btu are equivalent to 5040/115,000 = 0.0438 gallon (5.6
ounces).  We can subtract that from the gallon burned to get
(1-0.0438)=0.9562 net gallon consumed to cover the 45 miles with 45
stops.  The mileage with 100% regenerative recovery would be 45/0.9562
= 47 mpg, or about 4.5% better.

The recovery cannot be 100% because the hydraulic brakes come into
play, there are losses in generating, transmitting and storing the
recovered energy in the battery, and further losses in extracting the
energy from the battery and utilizing it to power the car.  I have no
idea what the overall recovery factor should be, but a 50%  value
would reduce the mileage value to 46 mpg, which is about a 2.2%
improvement over no regenerative braking.

Can't estimate how much gas is saved by stopping the engine at traffic
signals. etc, because I don't know the rate of fuel consumption of the
engine at idle.  However, the Prius brochure lists miles per gallon at
51 hwy and 60 city, and one newsgroup poster (Jeffry Johnson) reported
44 hwy and 52 city.  Both sets of data provide a crude estimate of
overall mpg improvement of about 18%.  Assuming the city mileage
improvement is due to braking + engine stopping (because there is
neither on the highway) and using 3% as the braking effect  gives a
15% improvement attributable to engine stopping  (any drag effects
neglected).

I pondered these results for awhile and it became apparent that the
advantages of the hybrid technology are not so much from regenerative
braking but rather from two factors: 1) stopping the engine at vehicle
stops, and 2) employing a small gasoline engine with an electric motor
for power boosts when needed. Ultimately, the gas engine has to
replace the energy expended in those boosts since gasoline is the sole
source of energy in the vehicle.

I know this is a bit long and that it does not answer the many
questions that can be raised, but it helped clarify my thinking and
maybe it will help some others.  Personally, I'm going to hold off on
buying a hybrid for a while.  Maybe a long while. Economic analysis on
the cost difference of the hybrid versus the non-hybrid when compared
to gasoline savings using current prices just doesn't justify
purchasing the hybrid. Come to  think of it, one can almost never
justify purchasing any new car on an economic basis :-)

That's a wasted step, just changing to a different unit of mass, and
one which is of no utility whatsoever in getting to the units of
energy you use below, British thermal units, which are not in the
subsystem of units which includes slugs.   Of course, miles are also
not part of the system which includes slugs, nor are hours, so you've
also had to do a conversion of your speed numbers to use slugs with
any meaningful results.  Another wasted step.  Then you've had to
convert the resultant ft·lbf to Btu.  Better just to use the pounds in
the KE formula, and mi/h for speed, then use a conversion factor from
lb mi^2/h^2 to Btu--and you can factor in the constant 1/2 factor as
well.  You can figure that out once and reuse it, rather than having
to waste time in so many intermediate calculations.

But what is this, a drone, a driverless car?  Don't you need to add in
the mass of the driver?  What is that listed mass for, a vehicle with
an empty tank?  Or one 1/4 full only?  Let's just throw in a little
more for driver and fuel (say you drive it from full down to a quarter
tank, so use an average value of 5/8 of a tank of fuel would seem
reasonable), and call the total mass 3100 pounds.

Better yet, just use the mass in kilograms and energy in joules, and
energy density of gasoline in joules per liter.  The calculations are
simpler yet.

You also have 44 more accelerations from 0 to cruising speed, each
requiring additional expenditure of energy over what would be used
just in normal maintining of speed in the face of friction losses and
those due to terrain, going up and down.

Weight and the slug are not different units of mass.  The units of
weight are force units, not mass. The slug is a mass unit as are
kilograms. As to the units of energy, I can use any I prefer.  If you
like Joules or kwh or ft-lbs(f), use them.

No big deal. Did the numbers on a spreadsheet.  Retired my slide rule
decades ago.

If you plug weight (pounds force) into the KE equation I gave you're
going to get the wrong answer.

Of course it's a drone.  I was just making a rough estimate to satisfy
my curiosity, ball park as some would say. Make any assumptions you
prefer. A weight of 3100 lbs would increase the kinetic energy by 7%
over my figure.

That's true indeed. Matter of fact, I did do it that way just for
kicks as well as the way I posted. I was raised in the English system
or something like it, so I still use it. Old habits are hard to break.
I even measure lengths in feet and inches.  Going to get a metric tape
measure some day. Would make life simpler.

Not relevant. All I needed was the kinetic energy stored in the moving
vehicle. I did tacitly assume level terrain. Should have stated that.

By the way, since this is the Prius newsgroup, do you have any
comments or opinions about the car?

No, "weight" is not a unit of anything.  Pounds are units of mass.
Slugs are units of mass.

>The units of
> weight are force units, not mass.

You are one confused fool, failing to understand the simple fact that
"weight" is an ambiguous word, one with several different meanings.

The word "weight" entered Old English over 1000 years ago, meaning the
quantity measured with a balance.  That quantity is mass, not force.
It was used as a measure of how much stuff people had, for the purpose
of trade.  We still use the very same word today, with the very same
meaning, for the very same purposes.

Weight is never a force when anybody talks about "net weight" of
anything, nor about "tare weight" of its container.  Naturally, when
products in American supermarkets and auto parts stores and whatever
include pounds and ounces for this weight, they are every bit as much
units of mass as the grams and kilograms which appear right alongside
them on the same label.  In fact, we no longer have independent
standards for those pounds; since a 1959 international agreement, the
common, worldwide definition of these pounds is as units of mass
exactly equal to 0.45359237 kg.

Weight is never a force when anybody talks about "troy weight" of
anything.  That's one way the troy units differ not only from their
avoirdupois cousins, but from grams and kilograms as well--they have
never spawned units of force of the same name.  There is no troy ounce
force, never has been.

Weight is never a force when anybody talks about "carat weight" of
anything (5 carats = 1 gram in the modern definition).

Now, Rod, it is your turn.  Like you said, those kilograms are units
of mass.  Now, why in the hell don't you just explain to us all
exactly what is done differently when this "curb weight" is measured
in pounds, from what is done when it is measured in kilograms.

While you are at it, tell us why in the world the manufacturers would
measure two different quantities for this purpose in the first place?

Or just wake up and smell the coffee.  Let's add another to my list
above: weight is never a force when anybody talks about "curb weight"
or "kerb weight."  It doesn't make any difference how they spell it.
It doesn't make any difference whatsoever what units they use to
express it.  Nobody in the whole wide world ever measures curb weight
in newtons, and nobody in the whole wide world ever measures curb
weight in pounds force.

>As to the units of energy, I can use any I prefer.  

You can.  But the only units of energy in the only subsystem which
includes slugs are foot-pounds force.

You don't have pounds force.  You have pounds mass.

If you use pounds mass and feet per second in your kinetic energy
formula, the result is in foot poundals.  It is just as easy to
convert foot poundals to Btu, as your calculations converting foot
pounds force to Btu were.

If the curb weight is indeed 1311 kg, as listed in one of the sites
above, at exactly what areas on the surface of the earth would that
much mass exert a force of 2890 pounds force, measured to the nearest
pound force?  Note that even if you limit yourself to sea level on the
surface of the earth, a mass of 1311 +/0.5 kg will exert a force of
from 2881.4 lbf to 2898.9 lbf (throw in elevation, including Mt.
Chimborazo, the highest mountain on earth in both ways relevant to
this discussion, and the variation on the surface of the earth is even
greater).  But 1311 kg is 2890 lb anywhere on earth, or anywhere else.

If curb weight were in pounds force, as you erroneously believed,
you'd never have more than 2 significant digits, if all you know about
location is that it is somewhere on earth.

It is indeed relevant to figuring any change in the fuel efficiency
overall.

I'm intrigued by the idea, but I've never even seen a Prius.

Thanks Bill.  You are right. He has no interest in the Prius, just
wants to show off his knowledge of an arcane subject. How do you
suppose he landed on the Prius newsgroup?  Do you suppose he Googles
newsgroups looking for people who abuse units? Chief of the Units
Police maybe? Anyway, I just put him in the kill-filter box and closed
the lid.

I didn't read beyond the insult (never do) but having spent a lifetime in
engineering, the topic boors me to distraction anyway.

I ordered a Prius on June 25th and was 9th on the waiting list.  I'm now 3rd
on that list and will be 2nd by the end of the month.  Mine will be black
with the 2005 level 6 package.  Is it worth it?  From the standpoint of
putting my money where my mouth is, yes.  It is my environmental statement.

True.  I bought the Prius primarily because it saves gas, thus extending
the petroleum supply, and (more importantly) it reduces emissions, thus
contributing less to air pollution than a conventional car.  By
themselves, that wouldn't have been enough for me to buy one when I did
(my former car was in great shape and was paid off, so I would have
waited until I needed to replace it), but the additional gee gaws in
package 9 (which is the same as package 6 in the 2005 model) tipped the
scales.

Thanks for the response, Michelle.  Your motivations are partly what
sparked my interest in the hybrids too, along with a concern not so
much for the price of fuel in the future, but its availability. In the
early 1970's I was in my lower 40's with a wife and children, working
for a major oil company in Texas in oil production research.  I
remember the oil embargo well, and I know how oil reserves are
calculated.  Done that.  Don't put too much faith in those numbers.
The input data are (is for you moderns) too uncertain. And as we know
now, the numbers are sometimes deliberately falsified.

I know what you mean by the "additional gee gaws". Geez, they grabbed
me too, and I came close to buying a  Prius because of its cutting
edge engineering.  However, I'm retired and don't drive much anymore,
and it won't be long before I'll be going to my Great Reward. I
wouldn't get much use out of any new car.

I keep cars a long time, too.  Drove a '63 volkswagon for 23 years. I
drive a 10-year old Grand Caravan and my wife drives a 20-year old
Toyota Cressida.  They'll make a few more years.

I did the rough calculations primarily from a curiosity about the
kinetic energy recovery. It's a lot smaller than I expected.

I'm retired too, but about a decade younger than you apparently are.  I
still put quite a bit mileage on the car, though; nothing other than one
supermarket is close around here.

Still, why not enjoy retirement by getting the "stuff" we like, even if
our remaining years are few?  My daughter and my SO are quite accepting
of my plan to leave just enough in my estate to cover funeral costs.

Well, except for the young part, you pretty much got it right.  We'll be
celebrating my 62nd birthday at the local Rocky Horror Picture Show in a
few weeks.

That too.

Well, you did get 4 out of 5, big boy.

Nothing wrong with that. ;)

I've met Michelle in real life.  She's an older sexy,

To save gas money, no.  To save on air pollution and foreign oil
dependence, yes.  If you want to minimize your direct expenses buy a
used Honda.

Thanks for the response Richard.  By the way, I didn't write the
question above; I wrote a respone to it, but I agree with your answer.
Well said! That's the story in a nutshell.

If all you want to do is save money, walk/bike.  You're already feeding
yourself anyways.  Otherwise, how about a nice used Honda Insight,
Honda Civic Hybrid, or Toyota Prius?  clean, good gas mileage, and
since they're used they're less expensive.  Or get an old diesel,
convert it to 100% biodiesel/veggie oil, not so clean but no more money
going for petro-fuels.
RZ - 25 Nov 2004 15:57 GMT
I have owned an Insight for four years.  I also just picked
up my Prius.  The Insight is a great car and you won't be
able to beat the great mileage it gets.  Love the Prius for
all of its other great features, but it won't touch the
Insight's mileaage.

Also, I was T-boned a few months ago, a woman with dialated
eyes ran a stop sign.  Nailed the Insight's passenger door.
The officer was amazed at how well it took the damage.  Repair
costs were amazingly low, under $3,000.

Well, after reading these posts and many articles I decided to get a
Prius, and I love it! The Prius had more room and features than the
Insight, and according to the EPA, better gas mileage (for automatics)
- and that's the whole reason for me getting a hybrid. I've driven
almost 400 miles already and it only cost me $13. A lot better than my
$30+ a tank before.

For the person who wrote "ride a bike" probably doesn't live in CA or
commutes to work.

Thanks for everyone's feedback.

Congrats, Aaron!

We now have 7000 miles on our '04 (purchased mid-July) and we cannot
imagine having a nicer or more economical vehicle. Although we're not
getting the 60 mpg that we've heard about, we don't baby it either and
drive 80 on most Interstate highways and 60+ on the state highways and
county farm-to-market roads.

We live in Iowa so it will be interesting to see how the Prius handles
the cold weather but we expect no problems whatsoever.

Our fuel savings have been significant and it handles and rides like a
dream. We truly believe that this is the best auto we've ever owned
and we've owned some nice Caddies, Oldsmobiles, Chryslers, etc., in
the past.

Good luck with your new Prius and I hope you enjoy yours as much as we
are enjoying ours!
