According to a report from, 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."

      This would be the best application for a diesel/electric hybrid in the US.

      They were expensive to buy, so almost nobody did. The returns were just not there. It was also a very expensive program to fund, and as a result, GM lost tons of money with no benefit. They couldn't even use it for marketing because the mileage was so bad.

      Until "They" get around the problem of NON-homeowners being able to re-charge QUICKLY at "Stations," Hybrids and all Electric sales will never fly mightily. In my city, I'd guess 3/4 of the population rents. Many have no driveways and "WE" sometimes have to park WAY from our residences. I can't offer any solutions sorry. Even if I get parking space in front of my home, I'd have to run up 3 lights to get and plug in an extension cord that somebody will likely trip over and sue me for. Anyway, I think most car chargers are 240V Not the 120 in most rented homes. If they can get MORE electric charging stations, AND keep the charge time to under 5 minutes, I MIGHT consider buying one.

      Type your comment here They might have found out it would be a waste with mitsubishi makeing an suv that is four wheel drive and will get the mileage of a chevy volt=====why waste the metal ( o yea, too expensive also)

      I'm getting really tired of these trolls. Most of them are just mindless fools who are campaigning for their favorite corporatist candidate, and know absolutely nothing about cars. This is an ENTHUSIAST site. Spew your political bullsh*t somewhere else, and stop hogging bandwidth. No one gives a crap what you think, or how mad you are that a black man is president. As for the topic at hand: The next truck series is supposedly lighter, will have a new generation engine, and possibly 8-speed transmission. These may give the truck good enough mpg that the hybrid is no longer needed.

      Why can't they do a twin turbo v6 diesel or a v8 diesel to replace the hybrid? Would definitely do much better mpgs! And of course for the purpose of trucks, hauling, would do pretty well.

      I'm suprized at this move. As a Auto Repair Tech in a GM dealership , I've driven the hybird trucks and suvs (I thought it was a joint venture with GM/Chrysler). The system works and seems too work quite well. But it was expensive, and in my area - where we drive mostly high-way, it wasn't really that usefull (i.e. - running mostly on the DIVC engine). In the end - I supose you don't buy a truck to save on gas.

      Politicians can make up any MPG target they desire. Nature, science and technology will instruct the politicians what will truly work or not. If the vehicle is not designed ot conform to the laws of physics and technology, it will fail to perform as the politicians desire.

      I own a 2 mode yukon denali hybrid and I see a HUGE improvement in efficiency. I used to gt 14 mpg in my regular denali, but with the hybrid I get at least 19 mpg average with aggressive driving. Anyone who is looking at a standard wheelbase denali should buy a hybrid.

      It would be interesting to know WHY they are canceling this program. If the results are not as good as expected, you'd think they would have killed it a whiles back so as not to waste too much money.
