Hybrids the Real Payback

edited April 2014 in Honda
I save on my 2003 HCH by getting 60+ mpg drivin smart, little brake wear, less oil changes with factory recommended 10,000 miles and less time stopped at gas stations.
The cleaner air doesn't pay me directly but is precious, the reduced imported terrorist oil for oil changes and gas fill ups is priceless. The encouragement to Honda to make EVen better hybrids is paying for Everyone. Each new model gets better. Just like PCs and Cell phones we will soon get 100+ mpg and never need oil changes.
Whats the payback on big fancy RIMS ? On leather seats ? On a monster sterio on a fancy paint job etc. Hybrid really pay off every mile.

    You have missed the point.

    If there is a hybrid and a non-hybrid model the payback between the two in gas savings alone is over 100,000 miles. If you are buying a hybrid for TCO then the payback just isn't there.

    Read the other discussions in the hybrid fourms. It has already been discussed and rediscussed ad infinitum.

    When you are looking at payback you need to make sure what you are comparing ;) And I agree there really is no payback on big fancy RIMS or leather either but what is the payback difference between a hybrid and an ICE both with leather and both with big fancy RIMS ?

    The payback vaiable under considertion (normally) is the cost savings between a Hybrid and a gas only(ICE) with the EXACT same features? Otherwise why not compare the savings on a Mercedes CDI compared to a Corolla to a Lotus Elise ?

    However, if you are a "green weenie" the hybrids have less emissions and that is the way to go, even though right now it is like spitting in the ocean.

    I consider myself green - in fact I am carless by choice. But I have always been skeptical of hybrids.

    I wonder if you saw the articles on research done by CNW Marketing, of Oregon. CNW set up a green energy scale that considers such factors as energy used to make the vehicle, energy to run and maintain the vehicle, and energy to recylce the vehicle.

    As it happens, the number one vehicle is a Toyota, but not the one hybrid denziens would expect. Indeed, the Scion XB won out, not the Prius.

    Some other interesting tidbits: the Accord hybrid is more energy expensive than the standard Accord. The lighter weight metals and the recylcing costs of batteries pushed it over the scale.

    The energy cost of working light weight metals cannot be overlooked. The new Honda Civic, with all its aluminum alloys actually will use more energy in its life time than the Hummer H3, which is primarily composed of heavy - but energy cheap - steel.

    I suppose the one trade off from a solely US point of view would be that the Japanese are the ones using the energy to make the hybrids. True greens should think beyond their borders, however.

    A fellow rider. Cool!

    I am lucky enough that I can take the mass transit to work. I have a Cannondale hybrid that I use for shopping and stuff on the weekends. I also have an Independent Fabrications for touring.

    Going back to my point above about energy costs making light weight materials, carbon fiber is one light weight material that does not use a huge amoung energy to make or work.

    As you no doubt are well aware, at present Cfiber is $$$. Maybe as production costs come down, it will find its way into more econo cars, making them greener to build as well as drive.

    Wow, I haven't been on this forum for many months--it's sure gotten hot in the past few days.

    I'm very happy with my 2008 Mercury Mariner Hybrid 4WD, getting 26 to 32 mpg, depending on conditions. I estimate the payback (in comparison with a 2008 Mercury Mariner Premier 4WD) to be approximately 6 years. I usually keep my vehicles for 7 years, so it was a go for me.

    One point missing in the posts above is that in full hybrids the Atkinson cycle is used, not the Otto cycle. The Atkinson cycle features complete (or nearly complete) expansion of the mixure during the power stroke, unlike the Otto cycle (where the expansion and compression strokes are the same length). Technically, in current engines the Atkinson effect is achieve by keeping the intake valve open for part of the compression stroke, thereby decreasing the compression stroke in comparison with the expansion stroke--hence the greater efficiency of the Atkinson cycle. There results, however, a slight loss of power and a slight increase in noise (as some of the gas is blown back to the manifold), compared with a similar-sized Otto cycle engine.

    At constant speed on an inter-state highway, a hybrid will do better than a similar-sized non-hybrid because a) the Atkinson cycle is more efficient than the Otto cycle and b) the CVT is used to place the engine in its most efficient band of rpm--more so than a regular automatic transmission can (although a "tall" overdrive gear helps here).

    Another thing that helps everyone, hybrid or non-hybrid owner alike, on the inter-states: drafting close a large 18-wheeler. This will increase your fuel economy by at least 1 mpg!

    I wonder if anyone can explain this one. Currently, all available gas/electric hybrids have a gas engine with a conventional transmission and accessories - a very complicated and expensive setup.

    The sensible arrangement would be to have a system, as used and fully proven for many decades in railway locomotives, whereby the gas engine is used soley as a generator. You then get the great benefit of electric propulsion without the need for elaborate transmissions and duplicated systems.

    I believe the auto industry has conned the car buying public into believing that hybrids are necessarily more complex, and therefore expensive than conventional vehicles. Transmission manufacturers obviously have a great vested interest in maintaining the status quo, and the prospect of electric propulsion motors, lasting at least twice as long as their gas counterparts must also worry the manufacturers.

    It is really quite simple. The more parts to break the more to replace. Once they get you past the 36k mile warranty it is a money making machine for Toyota. Kind of like the cheap printers we buy. It is the ink cartridges that pay the bills.

    There are probably a 100 sensors in the Prius. If each one costs about $600 to replace. Looks like a gold mine in the making just a few years down the road.

  • tpetpe Member Posts: 2,342
    I'm thinking that would require a pretty big generator. Probably at least 12,000 watts would be needed to maintain highway speeds. How many gallons of gas would a generator of this size burn in an hour?
  • midnightcowboymidnightcowboy Member Posts: 1,978
    hi_carb

    No a bad idea sorry you got such flip answers:

    Use an ICE for generator only, some storage media inbetween ( unldess you plan to run the ICE contiuously) then electric motor for the drive. Yes a pure EV car or at least an electic only drive motor/s greatly simplifies the transmisssion, even simplier than the touted plantary sun gear Toyota HSD transmission.

    Message #13 - no not becuase there arem ore parts and they will breakdown, that is an incorrect answer for gagprice.

    Message #14 - Not sure what point Terry92270 is trying to make respnding to #14, but alot of car dealer revenue is from service and maintenance. Now it is true that, it is more cost effective from a car delaers standpoint to have a fewer number of standaradized process and components.

    Message #15 - tpe said 12,000 kW is probably about right and but it doesn't take a lot of gasoline. For example the genrator output of a Prius, Toyota's HSD hybrid system is 30 kW ( 2 and one half times) and it doesnt't use a lot of gas.

    If that is the case, why does our Lexus dealer charge just double for the same exact replacement part as our independent Mechanic? Labor was quadruple the independent. I know bigger shop more expense econ 101. They are drooling when you come in after the warranty period. Of course they play both parts. This car has a lot of repairs needed you should really trade it in. After getting a $5000 summary of needed repairs we took it to an excellent Lexus independent shop. Total bill was $1100. Tell me they don't get into the car business to make money on repairs.
  • terry92270terry92270 Member Posts: 1,247
    My point was about Manufacturers, the comment was about Nissan, not some dealer. While dealers, some of them at least, view warranty revenue as a cash cow to be milked, companies like Nissan are not realizing the same financial gain as a dealer might.

    In fact, economics rule that the fewer repairs, the more repeat business and better word of mouth, equals more sales, and higher profit for Nissan Corporation. :)
  • tpetpe Member Posts: 2,342
    If the Prius system can generate 30 kW I suspect that is only for a very short burst. The battery pack can't store more than 1 kWh.

    Even if you don't have dual drive systems you have still introduced an additional energy conversion step. That will always represent at least a small loss.

    Except that this isn't true in the case of the Toyota/Lexus hybrids. The "transmission" in them doesn't resemeble a traditional transmission in any sense, really. The setup isn't complicated at all. The engine and electrical motors are permanently tied together through a very simple connection system. The programming that controls them all together, now that I'll buy as being complicated.

    The sensible arrangement would be to have a system, as used and fully proven for many decades in railway locomotives, whereby the gas engine is used soley as a generator. You then get the great benefit of electric propulsion without the need for elaborate transmissions and duplicated systems.

    As someone already pointed out, the conversion losses in turning the mechanical energy from the gas engine into electrical energy to drive the wheels is a little too much to make it practical for such a small vehicle like a car.

    The railway industry isn't the only one that has figured out how great it is to mate a diesel generator with electrical propulsion. Modern cruise ships and tugboats do the same. An additional bonus is that the same diesel generator (or generators) is also used to supply power for the ship's occupants (lighting, heating/cooling, cooking, etc).

    You are right - it's not VERY profitable for the manufacturers.

    But the service department represents 90%+ of the total profits of a new car dealership. This allows manufacturers to take a much higher percentage of each new car's price for themselves. That's why the dealerships still stay in business and make profit.
    Get it. If not you need a course in car business 101 - nothing to do with economics.

  • tpetpe Member Posts: 2,342
    I've never driven a Prius and I'm not all that familar with how it works but here's a question. My understanding is that for short distances at low speeds the Prius will operate in a pure electric mode. If you drive far enough the battery will eventually get depleted to the point that the ICE needs to kick in. When this happens is the ICE driving the wheels and charging the battery or simply charging the battery? My guess is that it is also driving the wheels. If that's the case it should be an indication that using the ICE as purely a generator is not the most efficient way to go.
  • midnightcowboymidnightcowboy Member Posts: 1,978
    TPE

    The HSD transmission is a big sun plantary gear with four connecting items: MG1 (electric motor/ generator), MG2, ICE and drive wheels. What isn't efficient is that when the "traction battery ( the one that powers the elctric MG1 and MG2) is full charges ( of maxmium 80% Toyota says) then the output of one MG powers the battery which then converts to electricity to drive the other MG. Double conversion; double conversion loss; no conversion is 100%. One reason why highway mileage is less than city mileage.

    MidCow

    P.S.- Were you awre that the Prius HSD system was designed to max out under the current EPA mileage testing? That is why real drivers ( except for a few focussed hyper ones) only average about 45 mpg.
  • tpetpe Member Posts: 2,342
    Despite what the EPA states for the Prius real world highway mileage is greater than city. Based on actual drive feedback it is something like 40/50 (city/hwy) instead of the 60/51 EPA rating. Although the greatest benefit of a hybrid system is derived in city driving due to the benefits of regenerative braking. By that I mean if you pull out the hybrid components on a Prius you will probably still get close to 50 mpg on the highway but probably no more than 30 mpg in the city.

    Only that's that not what is going on in the HSD system of the Prius, and you know that. Either that or you have being lieing all this time about having looked into the Prius extenisvely and understanding how it works.

    The front wheels are still tied directly to the crankshaft of the engine. The only difference is that some of the mechanical energy (22%) can also be used to generate electricity that can be put into the battery for later use, or used immediately for additional boost via the big electrical motor in the car. I don't really see that as ineffcient. I see it more as flexible and dynamic use of the mechanical energy being produced by the engine.

    How much mechanical energy of the engine of a conventional car is lost to such things such as running the A/C compressor, the alternator, water pumps, radiator fans, etc? Remember those things are tied directly to the output of the engine, or are powered by electricity generated by the alternator. Any mechnical energy being used to run those is energy not available to move the wheels of the car.

    I once thought as you did. What I eventually found out is that it's a lot more complicated than that.

    I recommend that you check out the following sites for a better explanation of how the HSD system works in Toyota's cars:

    http://www.wind.sannet.ne.jp/m_matsu/prius/ThsSimu/index_i18n.html?
    http://homepage.mac.com/inachan/prius/planet_e.html
    http://www.ecrostech.com/prius/original/PriusFrames.htm

    But to answer your question, when the ICE kicks in, it is used to drive the wheels directly and recharge the battery at the same time. Yes, using the ICE purely as a generator is not very efficient, which is why Toyota chose not to use it soley as an electrical generator for propulsion.

    MidCow"


    Actually, what happens in those rare cases (fully charged traction battery) is that MG1 (the electricity generating motor/generator) stops producing electicity. It simply spins freely. There are cases where MG1 will generate electricity which is then routed directly to MG2 (the big electrical motor/generator) to provide additional boost above beyond what the battery might be providing. This is usually when extra power is needed: passing another car, accelerating rapidly to get on the freeway, driving up a hill.

    What *really* isn't efficient is having 250+ horsepower engines in cars when 90% of the time the engine only needs about 50 horsepower to propel the sole occupant down the highway.

    The reason highway milleage is worse than city milleage is because the engine is being ran constantly at highway speeds. Whereas in city driving, MG2 can provide most of the propulsion, or the low end torque needed when starting from a stop. Smaller more efficient engine that doesn't need to run as often, can shutsdown at stop lights, and isn't oversized just so that it get going again after being stopped. That's why you can get better gas milleage in the city than on the highway.

    "P.S.- Were you awre that the Prius HSD system was designed to max out under the current EPA mileage testing? That is why real drivers ( except for a few focussed hyper ones) only average about 45 mpg."

    Can you cite specific information that backs up this conjecture of yours? The HSD system was certainly designed to meet future emissions requirements that will be stricter. And emissions certainly do go hand in hand with gas milleage. But I haven't seen anything that says that Toyota went "Hey, what if we designed a car that was engineered to take advantage of the EPA's outdated and broken testing methodogy for determining emissions and gas milleage?".

    Every car I've owned has failed to make the EPA's milleage estimates given the way I drive, and the places I drive to. It's a fact of life that I accept.

    There are a lot more than a "few focused hyper ones" who are able to achieve more than the average of 45 MPG. Hell, when my wife takes the car, she can get 50MPG easily, and she's not employing any special driving techniques.

    Not correct. Check back through all of the posts and discussion in the prius forum for the past 3 years.

    There is a definite reason why the highway mileage is less. It is because the MG is always spinning and is either acting as an eletric motor the M or is acting as a generator the G.

    devesienna said "The front wheels are still tied directly to the crankshaft of the engine."

    Then what happens at low speeds when the ICE is not running or other times when the ICE shuts off, do the front wheels skid along the pavement? Because if the front wheels were directly tied to the crankshaft of the engine, then the crankshaft would always be turning or the front wheels would be skidding.

    The again if the ICE is turned off on low speed and the eletric motors are running what do they connect too, to make the car run?

    Either, I am confused or you have redesigned the Toyota HSD system.

    First off, thanks for the information. You're obviously a Prius owner so I've got a question.

    Do you actually feel that you get better mileage under city driving conditions? In Consumer Reports road test they achieved 35 mpg in the city and 50 on the highway. They make every effort to conduct these tests under consistent and controlled conditions. Its hard for me to believe that they could be this wrong.

    I do disagree with your assessment of 250 hp engines being inefficient. It really all depends on how this power is achieved. Let's start with a fairly small displacement engine that produces low hp and torque and it will probably be fuel efficient. Now if you increase this engine's potential power by figuring out a way to stuff more fuel and air into the cylinders under full throttle it doesn't necessarily make it less efficient when it is only putting out 50 hp under cruising conditions. That has essentially been the trend with modern automobiles over the past 15 years. They have increased the cars potential power without sacrificing efficiency under normal driving conditions.
  • tpetpe Member Posts: 2,342
    Here's the way I see this issue. You have this mechanical energy being produced by an ICE and it can be used to either drive the wheels or drive a generator. Which option will result in the vehicle being able to travel more miles? Now the amount of energy required to turn the wheels will be the same regardless of whether they are turned by an electric motor or an ICE. If it somehow makes sense to use the ICE's energy to turn a generator why not then use the electric motor's energy to turn another generator, then another, then another, etc... Eventually you'll be talking about some really serious mpg.
  • gagricegagrice Pahrump, NevadaMember Posts: 31,450
    I think you are hoping for perpetual motion. Remember each of the MGs you add will be more weight in the overly plump Prius. The main reason the LRR tires that come on the Prius only last 10k miles is it is too heavy for the tires. They have optimized the Prius to the max and any added weight will probably have a negative impact on mileage.
  • tpetpe Member Posts: 2,342
    I am absolutely talking about perpetual motion, which of course is impossible. That is why this idea of using the mechanical energy of an ICE to charge a battery rather than drive the wheels doesn't make sense. Even if there was no additional weight involved it still doesn't make sense. That energy to turn a generator, to charge a battery isn't going to magically become more energy when when it goes from the battery to the electric motor.
  • gagricegagrice Pahrump, NevadaMember Posts: 31,450
    I think you and I are on the same keep it simple page.
  • daysailerdaysailer Member Posts: 720
    because of the cyclical nature of the driving environment - accelerating/decelerating, up/down hills, and the high peak/average power requirement.

    The current hybrids provide a means of energy recovery that is not available in a system that does not have a means to store that energy. They also allow use of a smaller and more fuel efficeient ICE than would otherwise be required since both drives in COMBINATION provide the peak power requirement.

    A series hybrid as in train propulsion requires that both the ICE and electric drive be rated for the full power requirement of the system. Road vehicles have a very different operating cycle than boats or trains which have a comparitively low peak/average power requirement and therefore would not benefit from a parallel hybrid arrangement as used in automobiles. An automobile OTOH requires upwards of 90hp/ton to be even marginally competitive with the current population of road vehicles while its steady state power requirement at highway speed may be only ~15-20hp.

    Unfortunately, the economics of current hybrids still do not make sense.

    I own a Prius, so I'll chime in here.

    Yes, you do get better mileage under city conditions. However, if it is extremely hot out you will only get good mileage for about 3 minutes or so. Once your A/C has drained the battery your mileage will suffer. The same goes for winter city driving, but for opposite reasons.. the engine has to stay on to provide heat.

    However, if it's nice out, you can do quite well in city driving.
  • tpetpe Member Posts: 2,342
    Does Consumers Union take into account the tax break given to these vehicles? If so anything can be made to make sense with the right amount of market manipulation. And they also don't think that they make a blanket statement regarding the cost effectiveness of buying a hybrid. They cite individual cases where it makes financial sense. For instance, they claim that a Prius makes sense when compared to a Camry. However the Prius wouldn't make sense compared to a Corolla. I'm not sure why they think that the Prius is more similar to a Camry than a Corolla. I don't see it that way.
  • terry92270terry92270 Member Posts: 1,247
    They compare the Prius and Corolla because they are close to the same weight and other Insurance Industry criteria, it wasn't something they pulled out of a hat. That is how one does comparisons..... ;)
  • tpetpe Member Posts: 2,342
    I agree, the Prius should be compared to the Corolla. What I've been seeing is the Prius compared to the Camry. I know that Edmunds makes this comparison. It tends to make the Prius look a whole lot better from a cost perspective. Not only is the Camry more expensive but it doesn't get the mpg of the Corolla.

  • daysailerdaysailer Member Posts: 720
    but the comparison is not necessarily logical or useful.

    There are many vehicles that offer better or equal performance and utility as the Prius at much lower cost. Even among Toyota's offerings, the Corolla, Matrix, XA, XB and Yaris come to mind.

    Even at $3/gal. it would require 150,000mi to recover a $5000 difference between a 45mpg Prius and a 30mpg something else and one can easily achieve more than 30mpg with even greater than $5k price difference.

    Payback periods measured in decades or hundreds of thousands of miles suggest rather risky investments given the myriad risks of vehicle ownership. What are the odds that one will actually own a vehicle long enough to break-even? Will the unrealized payback be reflected in resale value? It's too much of a long shot for me.
  • terry92270terry92270 Member Posts: 1,247
    And that is a perfectly acceptable choice, DaySailer.

    Not all car buyers use only a financial consideration. Some are motivated by the environmental picture, and what kind of world they will leave. Also totally acceptable.

    Those who are concerned about emissions, and can easily, without too big of a financial hit, help reduce them, will. :)
