       Those numbers might describe some mythical mean, Smith, but since I use about 600 gallons of gas a year, I highly doubt a hybrid is going to save me 500 of them.  Monetary descriptions aren't all that useful either.  My electric bill in Southern CA is going to be very different than Chicago or Dallas.  Running a space heater every night in December, or an AC in July would reliably jump my bill by $100.




Smith117 -> RE: Gas!! What will be your next Vehicle? (4/30/2008 10:33:16 PM)

I never said those numbers were "all inclusive." I was merely answering your question. If you don't like my answer, find your own.

And why would it not save you 500 gallons of gas if you use 600? Does 500 not easily subtract from 600?

What is this actually doing to the electric bill, though?  I'd really be curious to see how the power use of recharging an electric car compares to household appliances.

Approaching this theoretically:

A gallon of gasoline has around 131.7 MJ of usable energy, or 36.58 kWh. An electric battery/motor system can be around 3-5 times more efficient than a gasoline internal combustion engine, plus you get the advantages of a hybrid - no idling losses and reduced braking losses. The importance of those advantages varies by the type of driving you do - city driving gets a significant boost and highway driving less. In practice the improvement is probably between 1.25 and 1.6.* Dividing a conventional vehicle's fuel consumption by this "hybrid factor" and then the 3-5 efficiency factor should give a decent rough estimate of the electrical energy requirements.

Once done, and depending on the values used, the electrical energy requirement will be from 3.75 to 8 times less than the chemical energy requirement in a conventional vehicle, or from 4.57 to 9.75 kWh per conventional gallon equivalent.

Dependent on the efficiency assumption and what pricing tier consumption puts you in, the price in my area would currently be anywhere from $0.53 to $3.50 per the effective equivalent of a gallon of gas used in a conventional car. Of course if everyone jumped on board, that would be likely to go up considerably and might even overburden the grid.

*Using the fuel economy of the Honda Civic's hybrid (40/45 mpg) and conventional (25/36 mpg) versions indicates you might see a 1.6x improvement for city driving and a 1.25x improvement for highway driving. Dividing conventional fuel use by anything in between those two numbers is probably a decent estimate of what a hybrid would need, although you could break out and weight your city/highway driving patterns.

       Thanks, Shal.  My driving runs very heavy towards the freeway, 85%+.  Now, if we tack on the increased  cost of buying a hybrid in the first place, the smug simply costs too damn much.

     Smith, for a hybrid to save me 500 gallons a year, it would have to give me 150 mpg.


       "Saving the planet" will not enter my next car buying decision.  Overall cost will.  Last time, it was easy.  I already owned a massive, '68 pickup when my old compact truck started shrieking its death song.  The Dodge got 7 mpg, and drank nothing but premium.  I'd have put more money into her gas tanks every month than I wound up spending on car payments and gas for the Subaru, and that included the higher insurance costs of a car that wasn't paid off.

      I just don't see that happening by buying a hypebrid.

So now we see your real goal. A little swipe against hybrids with some outright falsehoods thrown in.

Unless you're a long haul trucker I doubt you consume 85% of your fuel on the freeway. Even if you did the TCO of a hybrid would be lower unless gas prices came down drastically due to the hybrids improved fuel efficiency. If you're unwilling to increase your electric bill then you're in luck, plug in hybrids are strictly after market conversions for the time being and are wholly unnecessary for the operation of the hybrid.

But ultimately buy and drive whatever you want, can afford and can get a tag for. But I would appreciate it if you didn't string people along asking questions until you got one you could twist to your viewpoint.

Dude, what posts are you reading that you think are coming from me? I haven't mentioned a 'hybrid' vehicle. I have REPEATEDLY said that the Volt is totally electric. It has NO combustion engine attached to the drive train. The only thing on the car that uses gas is a small generator that recharges the battery. Do you not know the difference between a small gas-powered generator and a 4-8 cylinder combustion engine?
 
Also, in my largest post about the car, I detailed the following:
 
0-40 Miles = No gas used. NO. GAS. USED.
Up to 60 miles = 150 MPG (That's what you said you needed, right?)
Up to 80 miles = 100 MPG
 
If you drove until the generator ran out of gas (12 gallons) you would, according to the makers, have driven 640 miles. That translates into an overall 53 MPG. However, unless you're doing a marathon driving session, you still get one of the mileages posted above. I already said this in one of my earlier posts.
 
As for pricing, well they haven't even set the price of the Volt yet, so you can't possibly think it's too much. The lead guy on the project said he wants it below $30,000 which would put it in the range of many trucks and large sedans. Sheeesh the Prius (an actual hybrid car) is only like $25K...or was when it came out...and I spent that much on my first new car that wasn't a hybrid.

        Nope, not a trucker anymore, Smith.  As I said when I first joined the thread, I live in a sprawling desert.  Doing 85%+ of my driving on the freeway is pretty easy.  That number is a conservative breakdown of my commute, and that isn't the slow-and-go, traffic-hell, of the freeways in the LA megalopolis south of me. 

       You're right though, you didn't mention hybrids.  You were talking about a vehicle that can't be purchased yet.  I stand corrected.

The Volt will be out by the fall of '09.

I'd think a sprawling desert would be ideal for a vehicle with a 640-mile range.

What does being a trucker or not being a trucker have to do with anything?




LaTigresse -> RE: Gas!! What will be your next Vehicle? (5/2/2008 8:58:32 AM)

Using fast reply..........

I am not going any smaller than my current vehicle. It is a Mazda Speed3 and gets 30+ miles per gallon. I drive about 120 miles a day, Monday thru Friday, all highway and freeway miles except about 2 miles of it. I tried the Prius and hated it. Have no interest in a slow car that can barely do 60 mph or one that will shoot my electric bill further through the roof.

I will just change jobs before getting a car any smaller.

I am with you on the Prius. I briefly considered one of those before I remebered I wanted a car with at least "some" balls. I drive a Scion Tc right now (the sportier-looking one) and it's got 160 HP and still decent mileage. I have just under a 45-mile roundtrip commute each day and can go 6 roundtrip commutes with some light weekend driving before I need to refill.
 
The thing that peaked my interest about the Volt, though, was that it's not like the 'hybrid' cars out there right now. It does what it does for 'mileage'  AND gets about 160 HP worth of muscle from its electric motor (that's 10 more HP than a Mazda3). When I saw that, I was definitely interested. Couple that bit of info with the absolutely sleek look of the car itself and I immediately added it to my list of 'potentials'.... second place on that list as well.  




LaTigresse -> RE: Gas!! What will be your next Vehicle? (5/2/2008 11:06:28 AM)

It's going to have to get alot less expensive than it's estimated 30K - 40K price tag before I will consider one. That extra $$ would pay for alot of gas........even at $4 gallon.

Actually, the Volt is supposed to be less than $30K, not between $30K and $40K. The lead design guy said he wants it as low as possible. As I mentioned before, the Prius costs roughly $21K - $23K. They were pricey when they first came out, but they quickly came down.
 
As a comparison, my car was $17K. According to my math, I spend $2,080 a year in gas, conservatively speaking. After 5 years, that's over $10K. So my car goes from $17K to $27K just by adding a conservative gas bill to it. That's not even factoring the interest in the loan because I haven't the time to factor that in right now.
 
So, the if the Volt comes out at $25K, for example. And I don't drive more than I do now, then I will have a $25K vehicle, compared to the $27K one I have now. The way I drive, a single tank of gas for the Volt could conceivably last me a year or more as I rarely drive more than the car's electric range or its 150-mpg range. 
 
Your Mazda3 ranges from $13K to $21K, depending on the model. So you could conceivably be coming in just under the "estimated" price for the Volt, or well over it. Also, your car's tank is 2 gallon's bigger than mine. So when you fill up, you're spending an estimated $7-$9 more than I do. Those figures, conservatively, come to about $46-$47 a tank. If you drive anywhere near what I do, then it's conceivable that our fill-up intervals are similar. So your car's gas for a year can safely be esitmated at just under $2,400.
 
Also you have to consider that the money you're talking about is on the 'back end.' If you work a deal with decent payments, or at least comparable to what you're paying for your Mazda, then you will still see immense savings as you are not spending $40-$60 a week in gas.
 
If they hit their target price for the Volt, and if it really does what it is supposed to, you and I could, theorhetically be $2,000 to $2,500 richer each year. That's a lof of cash I'm SURE I could find other uses for.




DomKen -> RE: Gas!! What will be your next Vehicle? (5/2/2008 2:36:51 PM)

My Prius cost a little over $25K from the dealer and the plug in conversion kit was another $2K. I don't know how you drive but the Prius has no problem getting up to Chicago highway speeds, north of 80mph, or staying there. I personally am not comfortable driving at those speeds so I don't do it often but I've never had any problems with matching traffic flow speed when I have.

The Prius debuted at that price, but their "MSRP" is now listed at just over $21K.

Assorted comments:

A Prius can easily do 60mph, and even 100mph+. In my opinion it's quite adequate for most people but, with that that said, it doesn't have the same performance of a sporty car like the MazdaSpeed3. Apart from the first few seconds of acceleration from rest (where the electric motors can actually deliver superior torque) the Prius isn't a match. If someone places value on extra, high rpm acceleration, the Prius won't be as attractive to them. That's not to preclude the possibility of a sporty hybrid, but the target markets tend to be different and I'm not aware of any presently available.

the TCO of a hybrid would be lower unless gas prices came down drastically

From a purely economic standpoint hybrids can make sense (and I'm in full agreement they're not just hype) - but it's not always a clear cut case. Assuming a hybrid can boost mileage by an average of 1.4x, the miles you need to travel in 10 years (about the life of the battery pack) to break even can be expressed as

x = 3.5 * (conventional mpg) * (hybrid price premium) / (mean cost per gallon of gasoline used over next 10 years)

Take the Civic. The conventional version has around 30 mpg and the hybrid version has a $5640 premium over the conventional Civic LX, or a $4590 premium when you factor in the $1050 tax credit. So, if you assume $4/gallon for gas over a decade you'd need to drive around 120,000 miles to break even. That's something some people do, but not everyone - nor does it factor in what you could have done over ten years with the money you save upfront.

Of course four dollars a gallon, even adjusting for inflation, is likely to be a distant, fond memory in 10 years. At $5/gallon, you'd need 96,000 miles. At $6/gallon, 80,000 miles, and so on. Until we actually start hitting those prices though, it probably does not make economic sense for everyone to buy a hybrid right now.

My personal feeling is that the energy independence and environmental benefits should factor into buying decisions for those who can afford it, but I realize not everyone cares enough, or is in the economic position, to make that a factor. Ultimately fuel efficiency needs to make financial sense for those people. In a larger sense, if everyone were to switch to hybrids, the cost of gas would stay lower and everyone would benefit - but it's hard to base a personal purchase on macroeconomic theory, sound as it may be. I fully support government subsidies of fuel efficient cars to help realize those macro benefits, though.

Plug-in vehicles, like a converted Prius or the Volt, presently may make more economic sense than straight hybrids if your driving is mostly short trips. The midpoint of my electrical cost estimates was around $2/gallon equivalent, which is likely going to be at least a 50% savings shortly (if it isn't already). The savings probably easily cover the relatively minor expense of a conversion for an existing hybrid (or the costs of adding it to new designs).

I'm not, however, completely sold on the idea of switching over to plug-ins en masse. If a sizable percentage of people start using plug-in hybrids, electricity costs will go up, affecting not just your transport energy expenses, but the entirety of your electricity bill. Even accounting for mostly off-peak usage, I think there really is the potential to overburden the grid - resulting in even more fossil fuel plants being built when ideally we should be working to replace the ones we already have with alternatives. Finally, if your electricity is coming mostly from coal plants, the environmental benefits are debatable. There may be some carbon savings (my rough calculations indicated perhaps 20%) but a probable increase in particulate emissions. If the electricity mixture is cleaner, it becomes a better option, though.

No, it won't. It's nice to see American auto makers finally doing something on the fuel efficiency front, but GM isn't exactly fast tracking it, despite the PR. The most recent statement from Chevrolet:
quote:

Although we haven't said exactly when the Chevy Volt will come to market, we've set our internal targets to complete the vehicle by the end of 2010. The specific date depends on the results of rigorous battery testing that's going on right now.

Not exactly inspiring confidence. There have also been some statements that it will be "in the showroom" by the end of 2010, but I doubt you'll actually be able to buy one until sometime in 2011. Even then, GM indicated that the first year of production is likely to see only 10,000 vehicles. Part of that is due to the expected costs having risen to $48,000. GM still seems to want to hit the sub $40,000 mark (sub $30,000 seems to be out), but is only willing to take limited losses. As the batteries become cheaper, they'll be able to ramp up production. I'll be happy to be proven and wrong and see a $30,000 Volt in 2009, but as even GM says it isn't happening, I wouldn't hold my breath.
