Ok now. Hybrid Diesels. GM already makes a Hybrid Diesel. It uses the Allison EV trans. The GM hybrid system most used is a Parallel system. It uses the electric motor integrated inside the trans at speeds below 15 mph for acceleration and then uses the diesel engine for speeds above 40 mph. In between these modes it "blends" the use of both to decrease emissions and to improve fuel economy and noise pollution. Go to any large Mass Transit system and you will find these vehicles in use. Most transit agencies use the Cummins ILS engine with the Allison EV trans. Oh. GM holds about 23% of Toyota. I don't remember if GM holds part of Isuzu.
  When the small diesel engines can "affordably" pass the new EPA standards you will see diesel hybrids. GM and Ford don't lag behind any other manufacturer. It all comes down to can they make money off of the product. Right now no. Depending on the market later. Maybe. Now for small diesel hybrids look at the Opel. For a nice Diesel model vehicle look at the Small Caddy and Chrysler models offered oversees. Just think about putting that same Opel engine in a Saturn VUE Hybrid. So don't think just because it comes from overseas it is better then what comes from the US. Ford, GM, and Chrysler sell to the US market what the US market will buy. Most buyers in the US market will not pay 30K+ for a small to midsized car. Try to get a European or a safe Jap model for the same price as a Chevy Impala or a Ford Fusion. Not going to happen. Stop knocking the US offerings. And again I say Honda is all Hype. Treat a Honda the way the average Ford, GM, or Chrysler gets abused and you will find the American cars are more cost effective.

Good information. 15 to 20 percent is most common for Diesel Hybrid buses used in City use. People don't realize that you have other auxiliary systems being powered by the power plant. HVAC, Lighting, Pneumatic and ADA required equipment. The average HVAC system on a transit bus is 70,000 btus That's about 6 tons. The biggest savings comes from regenerative braking. The alternators on a 40' transit bus operate between 3kW to 12kW depending on load required. All these systems get their power from the engine. This is before any forward motion by the vehicle.
So MPG is just one concern. Think about it this way. Lets say the Transit system is paying 50 Million a year for fuel. Take 15% due to Hybrid use. 50-7.5=42.5 That's 7.5 million. Use 20% then they reduce their costs by 10 mil.
Also the transit bus is kept in service for 12 to 18 years. I'll put it this way. Most transit buses I deal with average 26,000 miles a year of City 5MPH stop and go use. The vehicle is sold for scrap after about 15 years. So 15 times 26,000 is 390,000 miles. The average 40' bus gets 3.5 mpg. The Hybrids are getting 4.2 mpg. 390,000/4.2=92,857 gallons. Now use 3.5 we get 111,428 gallons. Say 18,571 gallons at $2.20 = $40,857. Now add the savings through brake ware. About $4600 per year. Then we get $69,000+41,000=$110,000. Also the lowered PM and NOx emissions to the city air pollution. The extra capital costs of the Hybrids are being covered by the lower costs of operation and impact on the environment. Right now it seems to be a wash.

Where in the world did you get any of this from the post about a Toy-uzu diesel hybrid. Other than the reference to GM/Izuzu link it said nothing about anything being better than anything else.
 
In fact..
I think the GM dual-mode is probably the best system for improving fuel efficiency in heavy vehicles.
 
However the blog entry indicated that this Toy-uzu diesel hybrid would likely be implemented in smaller vehicles like the Yaris/Corolla. Probably in competition to Honda's new small hybrid to be built in the Midwest.
 
But it's new and it's an interesting development for small vehicles.
 
All that other stuff about Caddy's and $30K vehicle and GM holds 23% of Toyota??????????? Are you into the eggnog early? Just show me the specific reference and I'll give your rant a little credence.

Read the posts and look past the last 6 months. Take a look at who owns who and you might learn something. It's not a rant. It is real.

GM sold off some of it's Toyota holding in late 2005. This has to do with some transfers in Fuji Heavy Industries and other companies. They still have some joint ventures and information sharing agreements. Toyota and GM have been working closely for years. Izusu has been with GM for years. Especially when Detriot Diesel was sold off about ten or more years ago. But I still don't rant!!!

Well Americans tend to vote with their wallets. The domestics declining sales and the Japanese increasing sales would seem to contradict that statement. Have we been duped?
 
I'm not bashing US automakers. I believe that they are just as capable of producing exceptional vehicles. Unfortunately they are saddled with financial constraints that interfere with the pursuit of quality.

It is a rant because I asked for a reference. Cite a source or a specific holding in GM's portfolio.
 
I know you said it's real just provide a specific source for your information. Then I'll belive you.
 
What you might have heard is that GM holds 20+% of their joint venture in Fremont CA ( possibly ) while Toyota holds 75+% of that plant. But that's the only joint venture.

Toyota is more likely to buy GM.

People seem to have a very short memory when it comes to Toyota and GM. GM has put the Capital monies up for joint ventures between the two for the best part of the last thirty years. Get intimate with the braking systems and engine on these two manufacturers. You will find some of the engine designs being swapped, sold or shared between the two. What is the I-force engine based on? I may be about 5 years off on the 23%, but you need to know the history of these two. GM is not going away. Different parts of the company yes. Don't be so short sited. GM as far as Hybrids are way ahead. They just don't see a viable market at this time. What penny pinching average Joe is going to pay 6 to 8K more for the same model vehicle and only get about 20% better MPGs. Ok for the slow people 30MPG +20% is 36MPG. Most people can't wait 5 to 10 years to recoup the added costs of the Hybrid system. Look at what price GM is going to Offer the Saturn VUE Hybrid. It will be equal in cost to the Honda Civic. A family can fit in it and still get about 32 on the highway. GM is changing to meet Market conditions. This is just a bump in the road.

LMAO!
 
Well, time will tell, won't it? GM's only profitable division is its financial services companies, like GMAC/DITECH. Same with Ford. They will go under with their pension obligations unless they get help. That much isn't in dispute. Perhaps they can turn it around......perhaps.
