According to a report from GMInsideNews.com, General Motors has shut down its hybrid program for company's next-generation of full-size pickup trucks and sport-utility vehicles. Currently, the Chevrolet Silverado, Tahoe, GMC Sierra, Yukon and Cadillac Escalade all use the two-mode hybrid technology.

Historically, the two-mode hybrid models have not sold well, and only yield minor improvements in overall fuel economy. In most applications, the two-mode hybrid system is rated at 20 miles per gallon in the city and 23 mpg highway.

GMI reports that it's unusual for programs like this to be shut down so close to the launch of a new vehicle – the next-generation trucks/SUVs are scheduled to debut for the 2014 model year – but that many sources within GM are not surprised about the move. These new full-size hybrids were reportedly supposed to use an updated two-mode system, featuring a smaller displacement V8 engine, upgraded battery storage (using a more modern lithium-ion pack) and revamped electric motors, according to GMI.

When contacted by Autoblog, a GM spokesperson only stated that the automaker could "not comment on future products or related technologies."

      Maybe they realized that an electric hybrid system is more innadapted and more costly for a weighty vehicule then a light vehicule like the small prius. Also if you want to do performance with such a system then the overall consumption increase and performance degrade like jeremy clacson in their program top gear discovered when they tried to race a prius against a bmw and the prius consume as much as the bmw and ran slower. Im pretty sure that a hydraulic hybrid system will be more adapted and more efficient for a big truck like this full size pick-up truck especially if you drive fast, accelerate swiftly with a lot of weight and passengers into the truck. But gm seam not interrested to invest anymore into that direction. All in all electric hybrid parralel system with a battery are useless except if you just hypermile a small vehicule for short ride but you have to pay a premium. As soon as you drive at a faster pace the system reverse and then drag the vehicle instead of helping it. This is so because the force increase at the square of the speed instead of linearly. The specs that is written by toyota prius are just a linear segment at hypermiling slow speeds and small distance and if you do a normal long ride then you end-up paying more for the car and a higher consumption.

      I could be totally wrong, but I'm not buying this report. Although I haven't had to time to read the new CAFE tome, my understanding is there are additional credits available for hybrid application in trucks. Pickup trucks in particular represent a big challenge for improving fuel economy based on their mission (haul/tow) and blocky shape. It's hard for me to believe that GM would leave these credits lying on the table, particularly when they have an existing system that could be improved. Ford and Toyota are discussing jointly a RWD truck hybrid system. Whether they actually develop one together or not is TBD, but where there are CAFE credits, there will be development activity and products on the road.

        "footprint" New CAFE standard; the larger the footprint, the less MPG they need. Maybe in 2014 they'll just make them wider and longer. Voila, we've done what Obama dictates.

          @EVnerdGene
          While it is true that fuel economy targets are going to be sorted by footprint, there is a limit. And that flat point is exactly where the heavier pickups come into play. So you don't get any "relief" for having a longer wheelbase pickup. In addition, more and heavier trucks are going to be included so even though the annual improvement for trucks is smaller than cars, it's going to be a challenge. While it is true that there could be some impact on wheelbase/tread in future cars to cater to CAFE, those key dimensions cannot be adjusted willy-nilly and have a knock-on effect on vehicle package and dynamics. President Obama did not "dictate" anything although he certainly was pushing for higher fuel economy standards. CAFE is a joint agreement. Although it's going to be tough to achieve, the automakers got one key thing -- consistency between California states requirements and the rest of the U.S. Trying to manage separate fleets with different requirements would have been almost unworkable for the manufacturers.

      I wonder if they are going to bring their light duty 4 liter class diesel instead. If they make it B20 compatible like their HD 6.6 liter diesel, they could actually save much more dino-juice than the hybrid. The added benefit is that there is a huge demand for diesels among GM truck buyers, unlike the light hybrid system that current buyers were not begging for on GM enthusiast sites. They definitely need something. A couple of MPG savings on these low mpg vehicles saves more gas in a year than even a 20 mpg improvement in something like a Prius.

        That'd be great. That's more of a highway savings than a city one, it'd be better for pickups but worse for livery SUVs.

        I really, really like your practical approach on diesel. I am sure we agree it is not the best long term solution, but every little bit.... Also, diesels in trucks...500,000 miles and as long as the drive train is upgraded, a small truck can tow a house. Good job man.

          Yes, definitely not the best long term solution, just better than what we have now. I'd like to see B100 from algae become reality, that would be another major step forward. A full order of magnitude battery improvement would make things pretty interesting too. The future will be interesting.

          Yes, that particular proposed diesel engine was pegged at 4.5 liters. I threw in the "4 liter class" to include more engines in the 4 liter range that Chevy also has access to. Any of the "light duty" diesel engines would do nicely in the place of the hybrid, but yea, that 4.5 liter duramax would be an awesome choice.

      If people werent buying them, people weren't buying them. If GM was losing money on the project, GM was losing money. Not some grand conspiracy. In the long term, maybe it is a bad idea. For this application, maybe the voltec drive train, increased in size, might be a good idea. Built in backup generator, for example. Look at it from the business standpoint, opposed to evil Rush Limbaugh blah blah blah. Businesses want to make money. I work with them. They have money crunchers examine every avenue, every situation, long term vs. short term. Pay more now, get more later...short term reward. If these were practical for fleet operations, they would have sold better. I know of companies going electric. I have seen some switch to transit connects due to the size and gas mileage. They have no affiliation beyond making money. Every time a green tech underperforms, Rush Limbaugh is not standing behind a (dead) tree, wrapping up his hands, laughing.... Sometimes, the stuff just isn't practical.

        No, you're talking about some mid-sized companies with 100 employee's or more who can afford a Financial advisor. Most small businesses, are owned by the owner, with 1-10 workers, and they listen to some college-dropout, drug addict, Bane Capital owned radio station know nothing, who gets his market share by GIVING THE SHOW AWAY FOR FREE.

      "...who gets his market share by GIVING THE SHOW AWAY FOR FREE." This is the business plan of all broadcast media, and many small independent newspapers. It;s a very viable plan, and has worked well for more than a century. NBC, ABC, CBS, FOX, and other broadcast networks (those are just TV, but all radio stations are the same) provide FREE content to anyone with an antenna.

        I don't agree. I expect these companies really can do the math. The hybrid saves about $0.10 a mile, as long as you aren't rolling on highway miles. How long does it take to get back the $10,000 price difference? 100,000 miles. And that's before any kind of time cost of money calculations.

          That's not a good payoff when you consider that the battery will probably need replacing by then. At that point, you are either buying it because you want to be more environmentally friendly ( unlikely for a truck buyer ), or you're making a bet that gas prices will go up significantly ( you're smart ). It's very possible that truck buying preferences make this kind of vehicle uneconomical to produce on a large scale, due to, as usual, typical American car buying habits! So for these cars i'd say go with Aerodynamics, weight reduction, and engine technology, if it were a car manufacturer. Just my 2 or 5 cents ;)

        Let's put it another way. Limbaugh is telling you these things don't work. But, a Romney Attack on Iran means $8 gas, and an unrestricted oil speculation futures market, with Big Spikes in Oil prices. The only way to protect yourself from this kind of Wall Street-Chicago Exchange Futures Market Speculation is to cut your fuel use by 60% or more: That MEANs a Hybrid or an EV.

      @Ford Rush Limbaugh is entitled to his opinion, just as you are. I am not typing in all caps, in a rage befitting our good friend Dan. So now is small business a bunch of mind numbed robots, because they did not buy GM hybrid vehicles? Are medium sized businessx good, because they didn't buy them either. Nor did big business. Nor did the general public. Nor did liberals who love the environment, but need large trucks. Did they listen to Rush Limbaugh as well? Or are their simply no small, to medium, to large businesses that are run by liberals who need trucks that love the environment? I visited a Lesbian Contractor once, and they had a bunch of rescu grey hounds, flowers painted everywhere, Obama stickers, and Ford F-150's. I cannot imagine that they are Rush Limbaugh fans. I also visited a bakery once where the owner was apoplectic about George Bush. I sat and listened as he ranted and raved, and occasionally screamed at employees (he had a camera system to watch employees around the plant, and a loud speaker so he could yell), and in his case, Nissan Titans. Not a Limbaugh fan. I guess Rush Limbaugh is all seeing, all knowing, The Mah-Hah Rushie, that he can tell all of these People what to do, and they do it! Yet, people buy more and more Prius's, Volts, and Eco-Boost vehicles. It really is getting pretty silly....
