Are GM's Big Hybrids Headed to the Chopping Block?


Before the Chevrolet Volt and GM's new eAssist models, the carmaker's hybrid offerings were mainly composed of a small number of dual-mode hybrid SUVs and trucks. Now there's some uncertainty as to whether those hybrids will be around when the next-generation models arrive, according to GM Inside News and

It's speculated that the Chevrolet Silverado 1500 Hybrid, GMC Sierra 1500 Hybrid, GMC Yukon Hybrid and GMC Yukon Denali Hybrid may get cut when the new models come in the 2013 and 2014 model years, according to GM Inside News, an enthusiast site. The forum says the Cadillac Escalade Hybrid may get renewed, however.

The models constituted GM's early foray into hybrid technology; they debuted just as the Toyota Prius was becoming a media and Hollywood favorite. Co-developed with BMW, Chrysler and Daimler, the dual-mode hybrid system pairs a gasoline V-8 engine and electric motors for an overall mileage improvement compared with the regular pickups and SUVs. Chrysler and BMW have already abandoned the system.

The dual-mode hybrids have sold poorly for GM; modest fuel-economy improvements are paired with a $5,000 or more price increase, according to GM was still enthused by its new in-house dual-model hybrid system when last spoke with the automaker, but those developments seemed to have stalled.

It's important to note that the hybrid scuttling has not been confirmed by GM. When GM Inside News published the article, GM's Vice President Mark Reuss replied via Twitter to the enthusiast site, saying the story goes to "new heights of irresponsible reporting" and "new lows in headlines from some rumor stated as fact. Unbelievable. Lazy, silly, and sad. Bottom barrel."

We'll have to wait and see what GM has planned for the models. Its new trucks are expected within the next six to 10 months; GM's new full-size SUVs will debut later next year.

A five mpg improvement does sound "modest" but when you consider that the stock 5.3 was rated at 15 mpg city, the hybrid bump amounted to a 33 percent increase in city mileage. At 20 mpg vs. 15 the hybrid truck driver saves nearly $1,200 for each 15,000 miles driven. I hope GM keeps the big hybrids - an insider told me their next generation dual mode hybrid system is a vast improvement over the current system. But I can see where it might not be worth it for most drivers if they manage to cut a bunch of weight out of the next gen trucks, and use cylinder management, more gears in the tranny and other tech to get 25 mpg or better highway out of a stock half ton.

15k miles per year, divided by combined mpg.

A hybrid tahoe uses 168 gallons less than a non-hybrid tahoe. A hybrid civic uses 128 gallons less than a non-hybrid civic.

The tahoe's hybrid saved an additional 40 gallons of gas compared to it's non hybrid counterpart compared to the civic hybrid.

Not saying one is better than the other, or that one is a better deal. It's clear though that an increase from 17mpg to 21mpg is as important if not more than going from 32mpg to 44mpg.


"It's important to note that the hybrid scuttling has not been confirmed by GM."

So why is this being reported on? And again I ask has the policy of this website, where unconfirmed information is supposedly not reported on, changed?


I've read many times on several other sites that General Motors was going to cut back or eliminate their hybrid program I thought it already happened. Given that a car is your second most expensive purchase did the right thing reporting it and it's why I come here.

That's why I have a hard time buying GM vehicles. They don't give their hybrid vehicles (volt) any time to gain acceptance in the market place? I figure the cost of batteries etc... will come down in price over time but doubt GM will stay the course long enough to see this? That is why they fail?

It would be unfortunate to see the larger hybrid SUVs discontinued. If you need room for 6-8 and an all wheel drive vehicle (for towing as an example) and you want best in class fuel economy - the hybrid Tahoe and Yukon fit the bill. Otherwise, there really aren't many options.
