I guess a persons views on reverse engineering depends on who's doing it. !

Old Technology!!! The theory and technology used here has been around since the 1970's. Toyota just put it in passenger cars. It is just too expensive!! You won't get the return on your investment as a consumer. Like I said get real. Since Toyota is starting to put 8 cylinder engines in so called work truck Tundra's (T100 name was trashed because it couldn't compete and didn't do well). Lets see how the drive trains hold up after 80K. The transmissions are going to fail between 60 to 80K. Time will tell.

Thermoelectric Device by transpower
Dec 02, 2006 (2:49 pm)
I checked the patent literature and found a 1979 U.S. patent for using a thermoelectric device to convert some of a hybrid vehicle exhaust heat to electricity. I ran a Google search and found that only the Toyota Estima minivan uses this or a similar technology. If 1/3 of the heat generated by combustion is ordinarily lost as heat, and if 1/5 of this could be converted to electricity (and sent to the hybrid storage batteries), this would give us an increase of overall efficiency of 1/3 * 1/5 = 1/15 = 6.66%. This should, therfore, be economically worthwhile. So: does anyone else on this list have more information of the appropriate thermoelectric device and associated wiring to use?

Is there a lot of anger bubbling up trying to get out? I get the impression that the 'T' word sets off something inside you that's 60 yrs old or so.
 
Pre-WWII trucks?
 
uh.. V8's have been in 'T' vehicles since 1998. They and the transmissions are doing fine thanks.

An answer to the anger whatever. NO! I'm just a little surprised of the Toyota hugging, foreign made is better then American nonsense your pushing. Just keep sending your money overseas and believing all the hype. As for the fullsize Toyotas having no trans issues, Wrong. Also how about Toyota being forced to recall about 1.5 million cars by the Japan government due to a lose of life steering component issue. Toyota use to hide recalls. What I'm tying to get through to a Toyota biased person is that Toyota is no better then any other auto maker. So get real. Or could you be employed by Toyota or one of it's dealers? Ask a contractor who depends on their work truck who makes the best truck. Ford!!! And I don't like Fords in general. I like GM and Dodge. GM makes the best V6 engines and most durable transmission in general. Dodge makes the best four cylinder engines and small FWD trans. Ford makes the best breathing V8's and the best Straight 6 cylinder engines. The best V8 is the one use in the Corvette. And Toyota makes Toys for people like you.
   Now back to what this thread is about. Hybrid Diesels.
For a small fuel efficent car or truck a Hybrid diesel is not cost effective. A diesel engine is more efficent then a gas engine by about 20%. The cost of adding an existing hybrid system to a small diesel will not be recovered for many years after purchase. Think about it. It doesn't pay to spend more then it will save in initial costs. Gm already has a small hybrid diesel. It can't be sold here because of the emissions requirements. This soon will be overcome. But again the existing hybrid systems other then a mild hybrid like the Saturn VUE will cost too much to be practical. There is new engine technology like the Scuderi design which should improve engine efficiency while lowering emissions. Should be more cost effective and practical in the next 5 to 7 years. Why pursue the gas electric which companies like Toyota and Honda are pushing. Your only seeing what is being presented, go deeper. How about the MYT engine. I think its neat but I really don't think it will be fuel efficent. The Scuderi design has the best chance. Have you looked at Eaton's electric hybrid and hydraulic hybrid designs. They use whatever engine the user specs. Guess what! These are all American designs. Go figure, Oh, but what about Toyota. Using old technology found in US engineering schools for years. That is what Teas me off. Just give it all away and our children will pay for their parents buying US technology used overseas and sold back to us and there go the jobs. Go ahead buy Toyota then stick your head in the sand. Be careful soon the US "sand" may be owned by "Toyota". Good Day.

No hugging. No vehicle is made by divine hands so all are subject problems and potenial recalls. It's how the problems are handled. After 17 years and $400 in total 'unexpected expenses' they've earned my trust. Even the Prius which had the steering recall done last month cost me nothing and in no way put me out. It's a non-issue, it's fixed, it's done.
 
Now the rest of this rant is just goofieness..some of it's hilarious. 4c? ( You must be kidding ). The best V6 now is made by Toyota or Nissan or even Hyundai.

And wait until you see what the new 5.7L in the Tundra does to the others. It is so far off the scale that you won't believe your eyes. How about this little tidbit.
New Tundra 5.7L vs F150 5.4L... The Tundra is faster 0-60 and then brakes to a stop before the F150 even gets to 60. It's ridiculous what this will do to the industry. Only the GMT900's are close to the new Tundra.
 
BTW don't be surprised if Daimler puts a bullet in the head of Dodge and Chrysler and keeps Jeep. Did you see yesterday that in order to move the 2006 RAMs which are becoming lot anchors Dodge has incentives of $15000 !!!! Despite how good they are... ... apparently it hasn't been reflected in the public's willingness to buy them.
 
Now back to our regularly scheduled thread..
 
For a small fuel efficent car or truck a Hybrid diesel is not cost effective.
 
You are sure of this now? What if Toyuzu comes out with an $18,000 hybrid diesel that get's 70-80 mpg in 2010?
 
Gm already has a small hybrid diesel. It can't be sold here because of the emissions requirements
 
You will have to give me a link to what this vehicle is because it is unknown to me? You wouldn't be making things up would you now? Where can someone find this small GM diesel hybrid?
 
Oh, but what about Toyota. Using old technology found in US engineering schools for years. That is what Teas me off. Just give it all away and our children will pay for their parents buying US technology used overseas and sold back to us and there go the jobs. Go ahead buy Toyota then stick your head in the sand.

Your anger is getting the better of you again. When GM relocates most of it's facilities to China and Ford sells off it's European parts and moves everything to Mexico and Daimler kills off Dodge and Chrysler... you better hope that Toyota and Honda and Hyundai step in and hire new people to make up for the ones the detroiters ditched.

Yo Toy boy. Here's your link http://www.gm.com/company/gmability/adv_tech/100_news/astra_011005.html and you definitly don't have a clue. But you have the right to your opinion. And your what if's for 2010. What are they going to copy and improve on GM's work again. Be real.

Let's back off on making comments about each other and stick to discussing the vehicles please.
 
It's VERY easy for these things to spiral into personal disputes, so let's back off a bit right now please.

Thanks for the link. It's a concept so it doesn't really exist but it does look interesting. Tks.
 
Rather than allowing Toyota to improve on GM's design...GM should just bring it to market first.. get the profits and take the glory.

You still don't get it. It's not cost effective. There is a "concept" called point of diminishing returns. And small hybrid diesels are past that point right now. Say if fuel costs go to $5.00 per gallon then maybe. A Hybrid diesel like the Opel should conservatively get 50 mpg combined. It's non-hybrid version 40 mpg. That is a 25% increase. At $5.00 per gallon that's $0.125/mile non-hybrid and $0.100/mile for the hybrid version. Over 150,000 miles the difference works out to be $3,750 in fuel costs savings. That will take 6+ years to recover the initial costs at $5.00 per gallon, longer at $3.00. At $3.00 per gallon it works out to $2,250 for the same 150,000 miles. Not practical!! Advanced engines which are more efficent like the Scuderi design are better solutions and are easier and more cost effective to Hybridtise. Now this is my estimate on when you will see this engine in production and used in a production vehicle. 5 years. Shortly after most manufactures get their diesel models to pass US EPA emission standards. When it comes to doing business glory has nothing to do with it. It's all dollars and cents. You can't eat glory.
