Talk:Hybrid Synergy Drive
From Wikipedia, the free encyclopedia
This article desperately needs a figure and a more consistent explanation.
It seems like this article should be broken up further. The performance aspects of the Hybrid Synergy Drive article center on the Prius. The Highlander (AKA Kluger) and the Lexus offer superior performance compared to the non-hybrid versions. They accelerate quicker 0-60, don't have limited top speed when the battery is low, dramatically better mid-cruise acceleration, and better MPG.

[edit] MG-T and MG-S?
Why use MG-T and MG-S here? Isn't that just being deliberately perverse, given that this article is specifically discussing Toyota's Hybrid Synergy Drive, and they use the names MG1 and MG2? --KJBracey 22:53, 12 November 2005 (UTC)
I used MG-T and MG-S in the original write-up because they're more mnemonic (for "torque" and "speed") than MG-1 and MG-2; my intent was to make the text easier to understand to the casual reader. (I own one of the darned things and I always forget which is which -- how can a casual reader expect to remember?) If you feel strongly about it, go ahead and change it -- thanks for asking first, though. zowie 23:43, 12 November 2005 (UTC)
- I know what you mean - I can never remember which one is MG1 and which is MG2 myself. But then if Wikipedia used Toyota's terms throughout the article, it might help us remember :) --KJBracey 16:46, 13 November 2005 (UTC)
[edit] List of vehicles available with HSD
Given that this section is inherently about hybrid versions, from the heading, personally I prefer generic vehicle names, rather than the specific versions. Looks neater, and specific versions will get messier when we get vehicles with more than one hybrid variant. Also "Toyota Camry is available with HSD" is a bit less of a tautology than "Toyota Camry Hybrid is available with HSD". Does this make sense? --KJBracey 06:45, 24 January 2006 (UTC)
- You are correct about the problems with saying "X Hybrid is available with HSD" so I am changing it to a list of vehicles with HSD and listing specific models. You may change it if you wish. I will, however, preserve the links to the conventional cars. CGameProgrammer 18:35, 11 April 2006 (UTC)
Should the stated release dates of these cars be the model year (MY) or the actual year they were or will be released? Currently it's showing actual year of release. CGameProgrammer 15:16, 12 April 2006 (UTC)
-
- "Model year" is a specifically US concept, as far as I'm aware, so I'd avoid it. Giving the year of release is unambiguous. --KJBracey 11:59, 13 April 2006 (UTC)
- Is it really? I thought the model year is a car industry concept. Almost no car maker change their car model on Jan 1 of each year, hence the model year seldom align with calendar year. For example, many cars change model around October or sometimes earlier for debuts. I wonder how non-US markets label a 2006 Prius produced in 2005 (first released sometimes in 2005) vs. a 2005 Prius that was produced just a month earlier? On the door jam of all the cars in the US, a metal plaque has the "model year" and the "manufacturing date" etched in. Are you telling me that Japanese cars sold to Europe don't have that info? Kowloonese 21:44, 13 April 2006 (UTC)
- No, we do not have a "model year". Cars can change at any point of the year. And they don't change on a yearly interval. They're marked with a manufacturing date. We never talk about the "2004 Corolla" or "2005 Focus". We might say "Mark 2" or "Mark 3". --KJBracey 09:18, 14 April 2006 (UTC)
- When you buy a used car in Europe, how do you tell one model from another if the model name stays the same? Even if you are picking a car from a new car lot, how do you know the Sept 2005 car you want to buy is the same as the Oct 2005 and not the Aug 2005 next to it? For example, the Accord and Camry has change body styling and internal feature or even engine design without changing the model name. Do you name them Camry mark 2 or Camry mark 3 etc? When do you introduce a different mark number? Who standardize on this number? The used car dealer or the manufacturer? In the US, each model year change a mark number because the car maker usually changed something in the design or production process each year and it is worth noting as a model year change. I know there are exception, e.g. 2004 and 2005 Prius are identical cars. Car makers usually add some visible external changes to indicate a model change too. e.g. the 2006 has many non-functional changes on the body to give out the clues. The MY serves the same purpose as the mark you suggested. Even if the model year is only a US concept, it is a concept that makes sense. If you don't read the MY as the production date, there is no confusion. If you know corporate accounting, fiscal year and calendar year seldom line up either, yet it does not stop people saying "the 2006 fiscal years starts on April 1, 2006 and ends on March 31, 2007." The model year is even more useful when the model year don't always change on the same day like the fiscal year. I wonder why the Europeans don't use it. Kowloonese 22:04, 14 April 2006 (UTC)
- The "Mark" numbers are informal names concocted by the public, and often aren't fully standardised. Eg for the Ford Escort, I believe there have been disputes over whether one version was the "Mark V" or just a revised "Mark IV". The manufacturers themselves just say "New" when they're introduced, usually - eg my 2004 Prius brochure says "New Prius" on the front. In used car guides, cars are listed by year of availability (eg Prius 00–03, Prius 04–). Minor changes of spec (quite common) are often not specially noted, but used car guides will list them, by month of introduction. I think the main reason we don't use "Model Years" is simply that manufacturers do not traditionally have a yearly cycle. The concept isn't flexible enough to cope with the irregular, and often frequent changes that happen. The manufacturers do not normally introduce regular changes just to indicate a "model year" change.
- Oh, and one other important point - in the UK, our number plates (registration plates) show the year of registration via a simple letter code. So you can instantly tell the age of the car by that. So you would normally refer to an old car as being "T-reg" (T registration) rather than 1999. So years often don't come into it anyway. --KJBracey 10:06, 16 April 2006 (UTC)

- Unless you include the month and year of the release date. Otherwise the calender year carry insufficient information when car models are concerned. e.g. A Oct 2005 vs. a Sept 2005 car can be two completely different models. Saying 2005 alone is ambiguous. Kowloonese 22:39, 13 April 2006 (UTC)
- I like Kowloonese' points. I'll change it to model year, but precede each year with MY. CGameProgrammer 23:23, 13 April 2006 (UTC)
- Well, what a mess. It now is pretty incomprehensible, at least to my European eyes. I'm sure I could work backwards to figure out when exactly these cars were sold, but it just looks like a deliberate attempt to obfuscate the facts. --KJBracey 09:20, 14 April 2006 (UTC)
- I hesitated to use monthly release dates because cars are released in different countries at different times. But I have no real objections to it so I'll keep it, and just make some corrections. It's true that having 2007 models released in March 2006 is quite confusing. CGameProgrammer 17:03, 14 April 2006 (UTC)

[edit] Proposal to merge with Comparison of Toyota hybrids
- Oppose - Hybrid synergy driver article is long enough. There is a link to the comparison in the HSD article. If people want to see the car comparison they can click on the link. Daniel.Cardenas 01:53, 21 April 2006 (UTC)
- Comment - I proposed the merge, on the grounds that Comparison of Toyota hybrids is not encyclopedic on its own; put in the context of a broader discussion of Toyota Hybrid technology, though, the table has merit. AKADriver 15:45, 21 April 2006 (UTC)
- Oppose - The table on its own is not encyclopedic, but it wouldn't really add much to this section either. It's comparing the vehicles as a whole, and doesn't really have much to do with HSD. Maybe a somewhat different table comparing the actual variations in the HSD (number of cells, motor power, engine power, etc) would be relevant here, but not that. --KJBracey 16:47, 21 April 2006 (UTC)
- Good point. Daniel, what do you think? Comparing these cars' hybrid systems that way (rather than on nebulous whole-car terms like "unique styling") would, I think, be very useful and encyclopedic. AKADriver 16:55, 21 April 2006 (UTC)
- O.K. I'll try to find that info and put it in there. If someone knows where it is I'll add it. Is adding this info what you are suggesting? Daniel.Cardenas 20:29, 21 April 2006 (UTC)

- Oppose - I agree completely with KJBracey. HSD is meant to be about only the operation of the HSD; it isn't meant to be a discussion of the vehicles themselves. In fact this article may need a bit of cleanup.CGameProgrammer 17:51, 21 April 2006 (UTC)
- Oppose - I agree with previous sentiments. Additionally, one can imagine the comparison page containing information about the relative reliability of the different models, comparison of sales figures, etc. Even if its "Encyclopedic" status is a bit weak at the moment, it clearly, IMHO, has much potential. The HSD is just one aspect of that comparison. Theflyer 12:34, 17 June 2006 (UTC)
- Oppose - This article deals with the drive itself, common to all the other cars. If there is non-HSD content in the article it should be removed to other articles. Since there have been no yes votes, I am going to remove the rename template. 205.175.225.5 20:27, 6 July 2006 (UTC)
[edit] Comparison of Escape Hybrid with CRV
Originally, someone claimed the Escape Hybrid's real-world mileage of 28-32 was "comparable to a conventional four-cylinder SUV such as the Honda CRV". This is B.S. A quick check at fueleconomy.gov shows the CR-V's real-world numbers at 20-24 for all versions (2WD, 4WD, manual, automatic) while the Escape Hybrid averages between 28-34. Probably a case of comparing real-world numbers of one car to EPA estimates of another. The Escape Hybrid is, in fact, the most fuel-efficient SUV in existence, as far as I am aware. Also it incorrectly stated Ford licensed HSD from Toyota, which isn't accurate. Ford developed their own technology but it was nearly identical to HSD so they needed a license from Toyota. CGameProgrammer 17:51, 21 April 2006 (UTC)
[edit] Toyota Corolla Hybrid
In 2008, the Corolla will also have a HSD hybrid version. [citation needed].
Moved from page, there is no evidence for this. However, Toyota will eventually release a version, as stated in their model refresh plans. Just a matter of time, but it is speculation at this point and I have moved it here for that reason.
