Supply issues[edit]

It is surprising to see that there is no mention of hybrid supply issues; I am a Canadian geologist, and REE supply issues are becoming a rather hot topic in many circles these days. Added a quick section about this, i'm not really sure how to put references into the reference section so hopefully some computer genius can do that for me! Would be happy to write more if the need be. (talk) 16:51, 18 March 2008 (UTC)


For comments on what exactly constitutes a hybrid vehicle, please see Talk:Definition of hybrid vehicle. CGameProgrammer 02:36, 29 April 2006 (UTC)

Referenced talk page is empty and has no article associated with it. - Ageekgal 17:18, 29 August 2007 (UTC)

True —Preceding unsigned comment added by (talk) 14:50, 28 July 2010 (UTC)

To be precise, the definition of a hybrid in the article is incorrect. Most hybrids don't have two power sources; they derive all their power from burning fuel, but conserve some of it from coasting and braking using generators and batteries, that would normally be wasted. This definition is correct for a "plug-in hybrid", which has two power sources, but it is not a generally referred to just as a "hybrid vehicle."Landroo (talk) 20:20, 11 April 2014 (UTC)

Market Response[edit]

received authorization from the author. asked him and he didnt care. its a website blog. not sure if they are a company or not, seems like a regular blog.

Hybrids as a power source[edit]

I removed "Once at their destination, some hybrids can be used as power source themselves which of particular use in commercial and military applications." partly for the obvious (writing) but also because hybrids have to be modified to do this, and also because it is not a feature unique to them. Many cars have 12V outlets and some even have 110V outlets (and no hybrids have 110V outlets) because they all employ batteries that are recharged by the engine to feed electricity to various elements. A hybrid might have a more powerful generator but all that means is the conversion is somewhat easier with them. Also Honda hybrids do not generate electricity by the engine, except the normal amount used for the regular battery (charged by exhaust gas). CGameProgrammer 18:15, 18 May 2006 (UTC)

Victor Wouk[edit]

I believe it would be interesting to make a page about Victor Wouk, the godfather of hybrid vehicles. Having some information about him, and having known him in person, I will make a first attempt. LHOON 18:45, 4 June 2006 (UTC)

Comments moved from Talk:Gas-electric hybrid engine[edit]

Talk:Gas-electric hybrid engine now redirects here - see #Completed merge from Gas-electric hybrid engine, below.

  Hi  I'm looking to change  my car to a hybrid  is there any way to do so?  I have a 1984 renault feugo

One thing you can do is make it a "partial plug-in hybrid". This system uses a plug-in charged battery to run the electrical system of the car so your engine isn't wasting fuel running the alternator. This system does that without removing any of the original components, so when the battery is dead, your car still works like it always did. More info is available at (talk) 02:11, 15 August 2008 (UTC)

It's much harder to convert a car from gasoline to hybrid than it is to make it a pure electric (for instance). Start by checking out hybrid and electric vehicle discussion groups at Yahoo Groups --Felixkramer 06:09, 14 Dec 2004 (UTC)

I thought GM's EV1 is a pure electric car. The last statement of this article does not match the article about EV1. Can some car buff fix this up? Kowloonese 22:46, 15 Sep 2004 (UTC)

I deleted the discussion of the EV1 as a hybrid--it was always a pure electric vehicle --Felixkramer 06:09, 14 Dec 2004 (UTC).


Would this article not make more sense merged into the hybrid car article?

Thryduulf 23:21, 29 Dec 2004 (UTC) Bold text yo.

I agree. It is badly named and the content is duplicated. Guinnog 21:18, 19 April 2006 (UTC)
Specifically, this article should simply be deleted and the phrase should redirect to Hybrid Car. CGameProgrammer 10:49, 23 April 2006 (UTC)
Yes, remove and redirect. It's more accurate to call it a gas-electric hybrid powertrain. The engine is just a regular internal combustion engine, and there are electric motors, and they are combined into a hybrid powertrain. --D0li0 08:38, 20 May 2006 (UTC)
Done --Singkong2005 (t - c - WPID) 13:50, 11 June 2006 (UTC)

Completed merge from Gas-electric hybrid engine[edit]

No objections (see comments above), so I made Gas-electric hybrid engine and its talk page into redirects, and merged some material that didn't seem to be covered here. A couple of things I'm not sure about, so I've copied them here:

Because the engine recharges the battery smaller batteries are required than in an electric vehicle.

Makes sense, but the article makes varying statements about battery size for different types of hybrids. Is it safe to generalize, that hybrids always have a smaller battery requirement than all-electric vehicles?

The battery storage and electric motor allows the engine to operate at its point of maximum efficiency, to be of a higher efficiency design, and to be smaller than non-hybrid applications.

(Emphasis mine). It seems plausible that if the engine is not required to operate in a wide range, that could allow greater optimization for fuel efficiency. Is this true? --Singkong2005 (t - c - WPID) 13:50, 11 June 2006 (UTC)

Why are gasoline-electrics more common than diesel-electric?[edit]

Perhaps someone can solve this mystery for me.

The article says, correctly, that Diesels are excellent at delivering constant power for long periods of time, suffering less wear while operating at higher efficiency. It seems that diesels-electric would be a far better choice for a hybrid. So why are the main hybrid vehicles, such as the Prius, all gasoline-electric? Is it just because they were aiming for the US market? --Singkong2005 (t - c - WPID) 13:57, 11 June 2006 (UTC)

Rather than why gasoline-electric is more common than Diesel-electric, why not just ask why gasoline cars are more common than Diesel? Mackerm 22:03, 11 June 2006 (UTC)
Double cost penalty is another factor, diesels cost more than regular gas engines. Add in the cost of a hybrid and it gets pricey. The question "why so few diesels?" is perhaps not accurate, they are close to half the passenger car market in Europe. More accurate might be "why so few diesels in USA?", and follow up "is it just a coincidence that the Big Three aren't considered strong in diesels and regulations on diesel are so, ahem, non-optimal?"--Gregalton 22:27, 12 November 2006 (UTC)

The big 3 don't sell many diesels compared to Europe because of much cheaper fuel in the USA. They'll sell whatever they think will make them a reliable profit - although my experience at GM Truck & Bus made me wonder why they were even in business. For my use, I've never found a diesel competitive. Capital cost & maintenance costs never justified fuel savings.Twslandlord 18:57, 2 March 2007 (UTC)twslandlord

"a hydraulic hybrid Ford Expedition returned 32 mpg–U.S." If this is considered an improvement over average fuel economy for an american car then buying diesel seems to be a logical choice, I don't see diesel engines costing more, in fact they are of simpler design and more robust than petrol engines, and my car (a 1.9 turbodiesel) gets 66.6mpg under normal use. You mentioned maintenance costs, there is a lot less that can go wrong with a diesel engine and they tend to be reliable up to 150,000 miles whereas a petrol car with 50,000 miles is considered worn out junk (talk) 11:11, 9 June 2008 (UTC)

unsourced text on plug-in hybrids[edit]

Car companies are working on plug-in hybrids, but current technology makes do not perform well."

What does the above mean? Is the above sentence trying to say that prototypes for electric hybrids have not preformed well due to issues with current technology? Thus should be made clearer if it is to be added back. Also, sources should be added that support the claim about the issues with current technology.

According to Dave Hermance, the Executive Engineer for Advanced Technology for Toyota North America, a plug-in hybrid in "electricity mode is only capable of 35 miles an hour top speed. It has fairly glacial acceleration performance and cost 15 to 25 thousand dollars more money."

The above should be sourced. Also, hasn't any plug-in hybrid advocates disputed the claims this a guy is making? The opposing view should be added to be NPOV. These claims seem all to similar to the controversial claims made by automakers regarding battery electric vehicles. --Cab88 21:57, 20 July 2006 (UTC)

Most hybrids won't last long on battery alone presently, owing to battery technology and expense. The present generation Prius's battery can't even run the car for 10 minutes without the need for the motor to cut in start recharging the batter. I know that's unsourced but I read it in an Auto Express article last year, about a plug-in modification to the Prius which involved fitting new batteries which utilised a different technology, to make plugging in worth while. (talk) 12:01, 13 June 2008 (UTC)

Expensive Hybrid Costs[edit]

My girlfriends family got a letter from Honda, offering to buy back their Insight. They said that they have to replace the hybrid battery every eight years and that it cost $8000.00 to replace it. There's no mention of that on here. Is it true?

they wound up not taking the offer, 'cause Honda didn't say why they wanted it back.-- 04:53, 25 August 2006 (UTC)

Car companies offering to buy back cars after N years is a common sales technique (the more cynical might call it a scam). Afterall if you sell them back your current car you'll then need a new one! I got such a letter about my VW when it was roughly 2 years old. The comment about the battery was probably just supposed to be additional incentive. Plymouths 02:11, 29 November 2006 (UTC)

Long article warning[edit]

Edit this article and get the message:

This page is 72 kilobytes long. This may be longer than is preferable; see article size.

32k is considered a good limit, so this really should be broken into sub-articles. I recommend at least adding {{template:verylong}} to this to alert editors. Brianhe 16:55, 17 October 2006 (UTC)

I made change discussed above. Would like to hear feedback on breaking out Types of hybrid vehicles into its own page and just having a short summary in this article. A similar approach was taken with Motorcycle and Types of motorcycle. Brianhe 03:52, 19 October 2006 (UTC)

Created Types of hybrid vehicle as discussed above. Brianhe 06:21, 20 October 2006 (UTC)

I restructured Types of hybrid vehicle and enhanced it with pictures illustrating the different structures, so that it may effectively replace the Types section in Hybrid vehicle, which can be substantially shortened. I would propose to replace it with a reference to the Types article, and leave just an overview of the main types (series, parallel, and combined) with diagrams for illustration. LHOON 08:17, 16 November 2006 (UTC)

I propose changing the section Hybrids currently available. I am not in agreement that the "main article" related to Hybrids currently available is the List of hybrid vehicles, as stated above at the top of the section, but I think that it does not have a relevant "main article". I don't agree that that list is as informative as this section. The information under this section would do well in its own "main article" that is not a list. So, to sum up my proposal, condense the section Hybrids currently available into a summarized form and put most of the information into its own new page.
A different way of handling this is to simply condense the section without forming a new page, because each subsection has its own main article; however, this would limit the connectivity and information, by not having a new article, and would possible require having "main articles" to go along with Other military vehicles, Taxicabs, and Two-wheeled vehicles. 02:56, 21 November 2006 (UTC)

I created a new page Petroleum electric hybrid vehicle because that is what most people wanted to talk about and moved most of the current content there. Perhaps it was too bold of a move or perhaps the right thing. Daniel.Cardenas 20:05, 28 November 2006 (UTC)

Personally I think it was a good call. I switched hybrid car to redirect to the new article since all of the car-related stuff went there and it seemed more appropriate. Should probably also create a redirect for gas electric hybrid vehicle for us silly americans :) . Plymouths 20:09, 28 November 2006 (UTC)
I think this was a good move as well because it gives us light vehicle enthusiasts more room to describe hybrid cycle and velomobile technology (I've done a bit today). --Theosch 18:59, 19 January 2007 (UTC)

Kind of off topic but wondering if you think this hybrid sail boat belongs in the article: Daniel.Cardenas 02:05, 29 November 2006 (UTC)

Actually hybrid boats do interest me a lot, but I havn't looked around yet where such things should best go. I'll come back here later --Theosch 18:59, 19 January 2007 (UTC)


Are there any hybrid trucks ? . --Mac 14:32, 8 January 2007 (UTC)

Depend what you mean by truck: GM offer Silverado, Ford the Escape (SUV), see the list in the WIKI Hybridvehicles article, compiled by the US gov. If you mean real 'Truck'; plenty, and they're nearly all refuse trucks, attempting to reduce urban emissions, where the extra weight of the batteries being schlepped about is made up for by the intensive urban usage of the vehicles. See 'Diesel Engine Progress' for occasional reporting of such introductions.Graumicchie 22:30, 13 January 2007 (UTC)

Forget trucks, what about passenger cars? Okay, I'm being a little facetious as there some pictures of hybrid cars accompanying the article, but under the list of hybrid vehicles, we have bicycles (at first I thought this was a joke), heavy vehicles - list includes trains and buses, rail transport - thought this was covered under heavy vehicles (btw, diesel-electric, i.e., hybrid, locomotives have been around for decades, but not because they are necessarily more environmentally friendly, which presumably is the thrust of this article since hybrids are an environmental buzzward), cranes - given the rather obscure application (why not call out hybrid cement mixers or backhoes separately too), I thought this was another joke, road transport/commercial vehicles - again wasn't this covered under heavy vehicles, ships - another funny, as early steam ships used sails chiefly because they couldn't haul enough coal to run the highly inefficient steam engines of the era all of the time so this was hardly an environmental solution, and aircraft - somewhat interesting, but hopefully the pilot will keep the main engines running during landings too in case he has a missed approach.

Spelling errors[edit]

The "Hydrogen" section appears to be pervaded with spelling error. As someone without knowledge of this area, I am unable to correct it. It's just distracting to read. —The preceding unsigned comment was added by Macetw (talkcontribs) 04:29, 17 January 2007 (UTC).

Remove "Fairs with hybrid vehicles" section?[edit]

I think the section "Fairs with hybrid vehicles" should be removed because soon every automotive fair will present hybrid vehicles. --Theosch 10:04, 8 February 2007 (UTC)

    • I agree. A section for fairs specifically for hybrid/alternative transportation may warrant a section. But just because a hybrid is there shouldn't be sufficient. Improbcat 19:14, 22 February 2007 (UTC)

Hybridisation: link or stub?[edit] insists on an own stub section for hybridisation. Is this in order to write something more about it? As it is, the information only warrants a link. What do others think? --Theosch 14:31, 12 February 2007 (UTC)

  • AS of now there is no content there, and a link to a disambiguation page that is completely unrelated. I'd say someone either needs to write some content there, or create a new page at say, hybridisation (vehicle) and link there. But I can't think of any useful content to put up there without it immediately turning into a link farm or how-to article. Improbcat 19:05, 22 February 2007 (UTC)
  • I removed the section and link when I re-did the article. If someone either creates the page it links to, or provides some content they can put that section back in again. Improbcat 16:18, 23 February 2007 (UTC)
  • The term hybridisation in reference to vehicles appears to be borderline on a neologism, but might be legitimate to conversion of a vehicle into a true hybrid. I reverted edits to a number of articles where someone appeared to be attempting to re-define the meaning of hybrid to include autogas conversions, which of course use the same engine as petrol. --Athol Mullen 22:47, 23 February 2007 (UTC)

Single engine is not hybrid[edit]

I note that the section of multi-fuelling (flexible fuel, dual fuel, etc) appears to suggest that some people believe that these are hybrids. Unless someone can reference this with a reliable source, this really should be re-written to clearly state that multiple fuels in one engine are not hybrids. Reducto absurdium, any engine with a knock sensor could be called a hybrid under this definition, since they can adapt to different fuel quality. --Athol Mullen 22:47, 23 February 2007 (UTC)

I must agree, what do you put in the gas tank of a 'hybrid' car? Gas, ofcourse. There's nothing 'hybrid' about it, better yet, the classic cars that handle both regular petral and LP-gas at the same time, those are true hybrids. It's just a hype. —Preceding unsigned comment added by (talk) 02:23, 20 August 2010 (UTC)

4 Engines, powers and fuel sources[edit]

My god is this section a mess. It seems to not know the basic functional differences between diesel and gasoline type engine, notes different fuels for gas engines *after* the article section on diesels. Gives incorrect info on them etc. I'm going to copy over that whole section to my user page and work on rebuilding it. I strongly encourage folks to come over and help work on it. I will post a note about the updated version here for review before pasting it back in. Improbcat 19:05, 22 February 2007 (UTC)

    • On second thought. After reviewing Petroleum electric hybrid vehicle and Types of hybrid vehicle I think we would be better served by mostly gutting the above section and primarily redirecting to those two articles. There is no need to duplicate the information here when those articles cover it more clearly and in greater detail. So that is the direction I'm goign to go with my re-write. Once again I'd like help and will post a note here before merging it back into the article. Improbcat 19:29, 22 February 2007 (UTC)
Thanks for improving it. I doubt anyone would mine if you made the edits directly to the page rather then slowly on your user page. Daniel.Cardenas 19:32, 22 February 2007 (UTC)
I usually do the edits on my user page so that I can pick it up and leave it off as I get time. Without worrying about half-completed sentences, broken links, etc. Improbcat 19:59, 22 February 2007 (UTC)

Major revision and purging completed[edit]

I purged over 14,000 characters from the Engines, powers and fuel sources , and in fact renamed that section to Petroleum-electric hybrids. The old section was loaded with a combination of material redundant to (and apparently lifted from) Petroleum electric hybrid vehicle, and a lot of information on different types of fuel for and types of internal combustion engines, which has little to do with hybrid cars, and seriously bloated an article that was supposed to be about any kind of hybrid vehicle. I also trimmed the bicycles section ,and combined the two sections on motorized bicycles. Finally I added a short history bit, jsut to expand the idea of what could be considered a hybrid.Improbcat 02:12, 23 February 2007 (UTC)

On the whole I think a good revision. I'll be checking a bit more closely to see if perhaps a bit too much was chopped. In any case, I think the "controversial" tag could be removed.--Theosch 09:59, 23 February 2007 (UTC)

Compare section/link removed[edit]

I removed the recently added Compare section as it only applied to petroleum-electric hybrid cars. And as such didn't need it's own section in this article. In addition the link in the section is a duplicate of a link in the Petroleum electric hybrid vehicle article and as such is redundant. Improbcat 17:45, 5 March 2007 (UTC)

Hybrid Question[edit]

I noticed a Toyota Hybrid recently doing something odd - which I hope someone could explain. It was off, and the driver was away, but it would periodically sound like it was a fan was on. Any idea as to why it was doing this? Gautam Discuss 17:59, 12 May 2007 (UTC)

Sounds like a thermostatically controlled fan. Three candidates... (a) Prius has an electric radiator fan (like on a regular car). (b) The temperature controlled fan to cool the traction battery (vent on the rear LH door pillar). (c) An aftermarket device to freshen cabin air when the car is parked with windows closed.
Be aware that a high proportion of Prius owners are engineers so it may not have been exactly a stock model. For instance a cabin air freshener may have been achieved by modifying the circuitry for the builtin cabin ventilation fan. Shannock9 (talk) 20:24, 18 February 2008 (UTC) (Prius owner)

Energy Related Development by Civilizations (category)[edit]

Reverted addition to anti-hybrid article[edit]

Regarding my reversion of the addition of this link -- it's little more than a poorly researched blog site. If someone wants to work criticisms against gasoline-electric vehicles into the article, it should be done so in the prose not by linking to a shakily documented blog site that has its own agenda (Autobytel). - Ageekgal 15:54, 13 November 2007 (UTC)

The very same website you're pushing, ironically, has a "Go Hybrid!" article as well, here. Looks like you need more and better sources.

what the **** is hybrid cars????!!!!!!!!!!!!!!!!!!!!!!!!!!! —Preceding unsigned comment added by (talk) 01:59, 15 February 2008 (UTC)

What is really missing in this article is a comparison with existing diesel technology. I don't understand why the Americans are so keen on hybrids, they only really make any sense in the city. Stuff like Bluemotion (VW) and Bluetec (Mercedes) and Efficient Dynamics Diesels (BMW) can provide a lower fuel burn per horsepower than the equivalent hybrid when on the combined cycle. I think BMWs 535d is a much better solution than Lexus LS430h, on the basis of the aforementioned argument. My BMW 120d returns an average of 55 mpg, which is far more than I could expect from a Prius, given that I spend half of my time on the motorway. (talk) 13:26, 10 June 2008 (UTC)

Few diesels are available in America because they have trouble meeting air pollution requirements which I see is starting to hurt European diesels as well.[1] Recent changes to the formulation of the fuel and better pollution control gear have occurred but the high price of diesel and lower availability are still issues. Rmhermen (talk) 14:59, 11 June 2008 (UTC)

Effects of Hybrid Battery[edit]

I want to bring up the issue of the Environmental affects of the typical hybrid battery. Does anyone have any suggestions/ references? Tourguide195 (talk) 07:25, 17 March 2008 (UTC)

What environmental effects? The battery is made of materials that are valuable and will be recycled, and they're no more toxic than the other materials in a car. Lifecycle analyses show the extra hundred pounds is offset by reduced emissions in operation due to increased MPG. You've been misled by "Oh nooes, shipping toxic batteries all over" rhetoric. -- Skierpage (talk) 22:31, 29 August 2009 (UTC)

In the section on Environmental impact of hybrid car battery, the phrasing of "batteries like lead acid or nickel cadmium are incredibly bad for the environment" seems inconsistent with the NPOV principles. Can it be more specific than just "incredibly bad"? The following sentence saying "the toxicity levels and environmental impact of nickel metal hydride batteries...are much lower" is unclear if this takes into account that the battery volume is so much higher than in a regular gas-fueled vehicle. I'm not arguing that the hybrid car batteries are indeed worse for the environment--just that the text currently in the article is pretty unconvincing.

Environmental issues[edit]

Could the section headed Environmental Issues do with some supporting references? The claims about lower emissions and fuel efficiency are not supported. They seem reasonable and I'm not challenging their veracity, but to maintain Wikipedia's integrity these claims look as if they need backing up. Perare (talk) 20:36, 24 March 2008 (UTC)

Actually you'd be right to challenge the claims. Most hybrids are pretty poor in terms of fuel economy in comparison to a modern diesel, "Consumer tests have shown that the current generation of petrol electric hybrids are little more efficient than a top of the range diesel." - BBC News Online, 2008 ( Just flicking through some articles from the motoring press backs up this stance. ([[User talk:|talk]]) 11:57, 13 June 2008 (UTC)

But those modern diesels tend to be European small cars. In the USA, the DoE's clearly shows available hybrids do better than available diesels. While in Europe, the Toyota Prius remains the lowest-emission large family car, see The latest BMW efficientDynamics diesels do get sensational MPG by adopting several hybrid tricks such as regenerative braking, engine off at standstill, electrically-powered accessories, etc., but I and other tried to clearly identify those as "not necessarily 'hybrid' features". -- Skierpage (talk) 22:50, 29 August 2009 (UTC)


I feel this article is too bias on hybrids being eco friendly .User:dolphin674talk

Hydrogen/battery hybrid[edit]

Added pictures, this text:

[edit] Fuel cell, electric hybrid

The fuel cell hybrid is generally an electric vehicle equipped with a fuel cell. The fuell cell aswell as the electric battery are both power sources, making the vehicle a hybrid aswell. Fuel cells use hydrogen as a fuel and power the electric battery when it is depleted. The Ford Edge Hyseries Drive is an example of a fuel cell/electric hybrid.

and placed phev and mild hybrid as subtypes, where they belong —Preceding unsigned comment added by (talk) 14:53, 6 April 2009 (UTC)

My edits were (partially reverted). Still stand by the fact that phev and mild hybrid are basically subtypes and should be noted as such by a triple = in the headline.

Also, the pictures from the vehicle drivetrain can be shown on this page aswell, and some silly pictures (eg the Bush picture; did Bush ever promote green vehicles or clean hybrids?) can be removed. A few pictures of hybrids are sufficient I think, replace by the drivetrain schemes

All in favor ?

Good writeup, thanks. But I've internal linked fuel cell so you can read how unready they are for prime time. And the lousy fuel to wheel efficiencies they have. Shannock9 (talk) 11:34, 5 December 2009 (UTC)

series vs serial hybrids.[edit]

The entire section labled "series hyrid" is incorrect. The description is a serial hybrid. The best way to describe a series hybrid is to think of the armature of the electric motor wound on the drive shaft of a standard ICE vehicle. Would someone with more time correct this error and add the correct description o a series hybrid. —Preceding unsigned comment added by (talk) 08:37, 15 May 2009 (UTC)

agreed. also, the assertion that electric vehicles with range extenders like the chevy volt are serial hybrids, is very questionable. seems to me they deserve their own category. i believe there are serial hybrid buses on the road that would make better examples. (but that's the kind of info i visited this page to find, so not perpared to provide it at the moment.) —Preceding unsigned comment added by (talk) 03:53, 15 March 2011 (UTC)

Eaton Corporation – Hybrid Power Systems[edit]

I moved all Fuel consumption & emission benefits to one place[edit]

The power train sections for #Mild hybrid and #Powersplit hybrid had paragraphs giving overlapping redundant benefits that apply to all hybrids. So I moved them to #Fuel consumption and emissions reductions. The article is shorter and clearer, I hope this wasn't controversial. -- Skierpage (talk) 22:21, 29 August 2009 (UTC)


I rewrote much of this section as it was very poor, more concerned with the type of electric motor used than explaining what a series-hybrid was. This sort of writing, and level of explanation, gives wiki a bad name.

It seems like the Volkswagen L1 has a special system for the cooling of the engine/electric components. Perhaps it can be mentioned here. See Talk:Twike (talk) 15:24, 30 January 2010 (UTC)

Regional/coloquial language differences[edit]

Just along the lines of region neutrality, is there any other word for the term "curbside emmissions" or (as it's in this article) "kerbside emmisions"? I'm used to the term curbside, so every time I saw "kerb", it threw me off. Can we use idling emmisions instead as it seemed to refer to the emmisions of the car when it's not using its gas engine to move anyway? —Preceding unsigned comment added by (talk) 05:21, 4 March 2010 (UTC)

Updated series section[edit]

The series section was exceedingly large and full of speculative and subjective language, as well as it had a lot of redundant information, described benefits that were not unique to a series hybrid. It has been pared down to a size that is comparable to the others and the speculation/marketing kept to a minimun. (unsigned)

First of all. SIGN YOUR POSTS!

Now while I agree with some of your changes and efforts in shortening up of the series section, we could have done without your own personal engineering asssesments as to the feasability of series type hybrids. I'm not saying they are neccessarily correct or incorrect, just that it is clear in your edits that you have an opinion on this type of vehicle that you clearly wish to voice.(the statement that the 1st series hybrid to reach the US market, the Chevy Volt was in fact not coming to market, pretty much shows where you're your coming from) Not the place. Stick to the blogs. Either change it to reflect a more neutral POV or I'll just revert everything you've done.WopOnTour (talk) 04:12, 5 June 2010 (UTC)

Vehicle type[edit]

It seems that, although there is a "Two-wheeled and cycle-type vehicles" subheadline, there isn't a "Four-wheeled vehicles" category. I would like to see this added, and in the paragraph, I'd atleast like to see cars and electric skateboards.

The "heavy vehicles" subheadline is not really well chosen I think; perhaps a alternative can be found ? Also, perhaps it's useful to add another division; ground, air and watervehicles ? (talk) 07:20, 16 August 2010 (UTC)

Definition (encore)[edit]

Do we really need a separate statement and link to a dictionary to define "hybrid"? The article isn't about "hybrid" and we already do have more specific definition and ref-link for the actual topic of the article ("hybrid vehicle"), so it's only weakly on-topic and definitely redundant. I've twice removed the addition by Colinsfergusons, so here's a place where he can explain why we do need it and see if there is consensus for it (i.e., WP:BRD). DMacks (talk) 16:26, 11 September 2010 (UTC)

I guess..i am wrong by adding the definition for hybrid vehicle..initially, i thought it would be a good idea to bit more clearance in that definition and i added..Not every time my guess going in the right way..I correct myself and post something which will improve the quality of article in wiki..Thanks for the enlightment...

'Tribrid' Vehicle Infinite Loop[edit]

It seems that there may have been some slightly over-egregious merging. 'Tribrid vehicle' also redirects to the Hybrid Vehicle page, but there's no Tribrid Vehicle section. Instead, there's a 'See Also' at the bottom directing to the now-defunct-and-redirected 'Tribrid Vehicle' page, which brings you back to the Hybrid Vehicle page which takes you to the See Also which takes you to OH NO WE ARE STUCK IN AN INFINITE LOOP SOMEONE HIT CONTROL C. More seriously, it might be worth salvaging some of the old tribrid vehicle article and putting it into this page as a section instead. Or at least getting rid of the 'See Also' entry. SeattleSparks (talk) 17:29, 31 May 2011 (UTC)

I've removed the link under 'See Also'. The old Tribrid article looked quite stubby, with no references; so I am not sure its content is worth creating a section here.--Dbrukman (talk) 04:14, 15 April 2012 (UTC)

Electric cars with on board turbogenerator/chargers[edit]

I wonder; it seems this is where the future is: with turbogenerator, on board batterry chargers:


The 100% electrical car is simpler: requires no clutch or gearbox, is lighter, can have regenerative braking, variable speed capabilities, requires less maintenance and is cleaner. The on-board generator, powered by turbogenerators, instead of pistons, is cleaner, lighter, requires less maintenance and can use different fuels (in this scarce oil supply times).

Petro-hydraulic section is too long[edit]

This section, (most of?) which was added on May 10, 2012, does not fit well in context of the (already very lengthy) article, plus it seems to verge on an advertisement or press release. However, I am not challenging veracity, since it appears to be well-cited.

My recommendation would be for the author to edit the section down to a 2-paragraph summary, which is about the length of all the other hybrid technology summaries, and to create and link to a main article of his/her own creation.

Power-split or series-parallel hybrid[edit]

It's a key design aspect that these have at least TWO electric motors, each in some modes becoming a generator. Power flows from one electrical machine to the other to emulate a CVT (including overdrive). See here for more including citations.

Hybrid cars with very little energy storage capacity in electrical storage device[edit]

Nowhere in the article is it mentioned that in theory, electric cars can be made without using any batteries whatsoever. This is useful as these pack a great amount of weight, need to be replaced after a few years and make up the bulk of the cost. Rather than using a battery, a range extender (ie microturbine, IC engine or Stirling engine) can be used. Especially microturbines (which are ?% more efficient than IC engines, ie regarding incineration) are very useful, as they are very light, and (as any range extender) allow to use energy dense fuels (more energy can be taken along compared to batteries). The only downsides of a fully battery-less system like this is that it may then be even more efficient to just use a microturbine powered by the fuel (as in the system proposed the microturbine needs to operate all the time anyway), and reducing output power (by reducing the fuel consumption) is also a problem. A intermediate system may thus be more efficient still, having only a small buffer (so storing say energy to drive a few hundred meters upto 1 km, rather than storing energy for say 100 - 500 km). This could be done by placing a (ultra)capacitor in between the microturbine (now fitted with a dynamo or alternator) and the electrical motor. Note that although one may perceive this setup as not that environmentally friendly (compared to electric vehicles which drive purely on their battery capacity), it actually is allot more environmentally friendly than most internal combustion and hybrid cars. This as: less batteries are required (environmentally polluting to produce), microturbines burn fuel more cleanly than IC engines, and finally, the fuel itself can be ie biofuel or a emissionless fuel (nitrous oxide, hydrogen, ...).

Liquid Nitrogen and Waste Heat[edit]

I deleted these as power sources - nitrogen (liquid or otherwise) isn't a source of chemical energy, and waste heat, by definition, isn't capable of any further work. — Preceding unsigned comment added by (talk) 13:12, 10 September 2012 (UTC)

Hybrid vs Dual mode[edit]

A dual mode train (e.g. the AGC mentioned, or old BR class 73 for example) with both onboard diesel engine or ability to pick up from external electrical power supply (but not capable of using both simultaneously) is NOT a hybrid in the automotive sense. To be a hybrid and therefore to be included in the same article as the mainstream automotive hybrids such as Prius etc. a "hybrid" vehcile of any type must have more than one motive power source, must exchange power/energy between those power sources on the fly (e.g. to recycle braking energy), and must have some energy storage capacity(ultracap, battery, flywheel, hydraulic accumulator, compressed air).

"Military off road vehicle" incorrect?[edit]

It claims that it was first tested in 1985, sounds very early to me? Two links proved doesnt give any clues. Alexmcfire (talk) 19:59, 30 January 2013 (UTC)

section 4.4 series hybrid[edit]

This section seems to be factually wrong and has some facts missing. Diesel-electric railway locomotives and ships are not hybrids; they are diesel vehicles with electric transmission. A hybrid must have stored electrical energy in order to decouple the IC engine from the wheels or propellers, so that the power transmitted for locomotion is not necessarily the same as the power developed by the IC engine at any given moment. Important fact: a series hybrid should be designed to have it's IC engine running constantly at it's best specific fuel consumption point (SFC) generating electricity at a rate which is a bit more than that required for a typical urban journey. Then, for highway journeys where the average power required is more than that for an urban journey, the engine must run at a speed and load away from it's best SFC, or an extra engine/generator should be used to supply the extra power required. If the primary engine/generator is configured for best SFC at highway levels of power it will not be efficient when producing the average power required for an urban journey. — Preceding unsigned comment added by (talk) 17:30, 21 April 2013 (UTC)

~ yes I agree. Actually all the examples seem misleading, they miss the core principle of series hybrids. Plus the BMW i3 is a series hybrid in production, the Mazda 2 erev due next year is another. Greg (talk) 05:43, 9 November 2014 (UTC)

Units of measurement[edit]

All measurements found in this article must be converted to SI units: power, fuel consumption rates, etc. It's a good opportunity to people not used to meters, kilowatts and km/L to get used to it. The Internet has thousands of free programs for unit conversions so does smart phones. — Preceding unsigned comment added by Tiago65 (talkcontribs) 18:13, 23 October 2013 (UTC)
