General Motors will unveil its two-mode hybrid SUVs — the Chevrolet Tahoe and GMC Yukon — at the Texas State Fair today. GM has also released fuel economy ratings for the Tahoe and Yukon hybrids. Two-wheel drive models received an EPA rating of 21/22 mpg city/highway while all-wheel drive lowers the ratings to 20 mpg in both city and highway driving. All models come equipped with a 6.0L V8 — for a combined output of 332 horsepower and 367 lb-ft of torque — and can tow up to 6,200 lbs.
The hybrids also use GM’s cylinder deactivation system which allows the engine to run on just four-cylinders at cruising speeds. According to Automotive News, the SUVs can go up to 32 mph using only electric power, with the system using the gasoline engine or a combination of gas/electric at higher speeds. GM also used light-weight materials and aerodynamic exterior body pieces to help improve fuel economy.
The use of the two-mode hybrid system — developed in a joint venture between GM, DaimlerChrysler and BMW — makes the Tahoe and Yukon hybrids the most efficient vehicles in the large SUV segment. In comparison, the Nissan Armada and Ford Expedition return just 12/18 mpg city/highway and a Toyota Camry four-cylinder matches the hybrids’ 21 mpg city rating.
Prices have yet to be announced but are expected to start in the low $40,000 range. GM is planning to sell a total of 10,000 Tahoe and Yukon hybrids annually.

Doesn’t the Acadia/Enclave/Outlook trio already do better than this, mileage-wise?
Hybrids are useless (other than the fact that they sell well to retards).

Let’s see, a full size vehicle that can carry eight, all of their luggage and tow 6,000 lbs…AND get’s the same fuel economy as a 4 cylinder Camry???? I wonder how the GM haters will deal with this?

The question is, what’s the REAL world mpg like? What if I tool around town in one for a month doing normal driving, what is it going to return?

The new EPA rating is much closer to real world…that is why it was changed. The old standard would have shown the numbers as much as 10 MPG better

Any improvement to the mileage of a vehicle is good news, especially when it doesn’t sacrifice performance or comfort. I’ve always thought it would be most logical to apply hybrid technology to the largest vehicles first, and then apply to smaller vehicles. For example, driven 15000 miles per year, a Honda Civic Hybrid burns around 90 gallons less fuel than the non-hybrid Civic. For the same miles, this Tahoe Hybrid will burn 250 gallons less fuel than the non-hybrid.

Good luck getting 20 mpg carrying the eight people and their luggage while towing 6,000 lbs..you’ll be right back into the low teens just like their gasoline counterparts. Give me a diesel, thank you.
You hit it right on the head, Deanster. New EPA guidelines and ratings or not, all I care about is real world economy.

the Acadia does NOT do better than this mileage wise.
This is a good bump for such a heavy truck with 6.0 litres pumping away… my 6.0 averages 12mpg, on a good day. The Yukon version is a bit ugly though, but im glad they went ahead with this.. diesel better just be next.

We all know that EPA numbers mean nothing, but let’s give GM some credit here. It seems like all I’ve heard lately is GM needs to get on the hybrid bandwagon. Now here they are, and they’re getting crap for it. Personally, I’ve thought all along that hybrids are a fad and will disappear faster than most fads. But if you’re needing a vehicle that can tow and haul up to 8 people and want to be a little green, isn’t this something you should look at? Even if when you’re towing you don’t get the optimum mileage, you should get it the rest of the time while the electric side is running. And I see that as a good thing.

Thought the Acadia is rated at 18/25 on the new rules, or thereabouts. That would average about the same, but a lot less complexity.

Cyclone, Texas is a lot more green and enviro-conscious than stupid stereotypes let on. It is home to the largest windmill-electric generation farm in the country, people don’t toss crap out their windows like in Cal, and here in Austin “going green” is pushed probably worse than in San Fran. Not to mention that TX has one of the more highly educated professional workforces in the western world.

It is very significant event for GM. Granted the price probably will be a killer, but I can see Governator and the rest of public elected officials riding in those. If they can transfer cylinder deactivation technology to diesel, GM will have a valid two-prong aproach.

From a marketing perspective, wouldn’t pairing the two-mode to a 5.3L be a better choice? After all, greenies are wowed by the magical EPA estimates on the Monroney label. How can I justify selling a larger, more expensive engine that gets the same fuel economy as the smaller, non-hybrid model?
09/27, 11:09 AM

A GMC Yukon with the 5.3L gets 14MPG city under 2008 EPA. The hyrbid gets 21 or 20MPG in the city. That’s a big ass difference. The highway mileage is not very significant.

Yes it is 9around town, not on the road/highway). For the price of 2 Camrys you can drive 8 people with same fuel efficiency. Perhaps I am not that observant, but I am yet to see any of those monster rigs with 7 or 8 people in them. 30 years ago Suburban was a vehicle for a construction foreman. He did need it to bring less documented crew on the project (those who could not “huble englese”). The choice of transmission was “three on the tree” and it was usually parked on slight hill to start in the second. Why mother of 2 toddlers needs something like that to haul her brood?

Regardless of how many Camries you can buy with 40 grand, this provides the same mileage as them and is able to do towing and so on (which some people who want to be eco-friendly need, but they can’t get out of a Prius or whatever)

Yes, but will GM have competent service techs to work on them. Also, what will the warranty be on this unit, and its pieces versus GM’s standard vehicles? Kudos should GM pull it off comprehensively, but thumbs down if customers are sitting at their dealers service lounge waiting for their Hybrid 2 Mode juggernaut because of problems.

It doesn’t matter what they come with, the Tahoe and the Yukon are big favorites when it comes to American cars and especially when it comes to SUV’s. If GM’s marketing team does their job right this could be a big turnaround for the company. The thing that surprises me most is the price; for all the new hybrid tech thats going in (like the cylinder deactivation), I would have thought this would be upmarket. It’s going to be interesting to see how these sell, perhaps there will be another SUV Armageddon upon us as if it was 2000 again.
P.S. I hope not

Autonut, you’re a ****ing weird guy. In a good way, not bad – it appears that English isn’t your first language, then you use phrases like “Three on the tree” and “haul her brood” and it makes me think, no, you speak English, you’re just semi-illiterate….

According to my software, the standard 3/36, plus 5/100 on drivetrain, 6/100 corrosion, 5/100 roadside. I agree that a good warranty means nothing if the customer is constantly in the shop (right, Hyundai owners?), but GM seems to be getting good stuff out there lately. We’ll have to see…

The mileage estimates for this thing ARE impressive—IF they actually get that kind of mileage. It’ll be interesting to see how they actually do.
I’m also curious about owners’ actual mileage on the new Lambdas. Does anyone know of a website or a blog for that? I’ve looked at all of the Lambdas, and I think they are all really impressive vehicles. They’re very well-made, and believe it or not, I like the styling of the Outlook the best.

Why does GM seem to think that their hybrids ought to have weenie-looking wheels? This Tahoe has weenie-looking wheels, the Saturn Aura Green Line has weenie-looking wheels, and so does the ‘08 Malibu hybrid. Has anyone else noticed this? Is there an engineering reason for this?

bliss see what happens when car companies work together, mb, bmw and gm have been swapping trannies with each other ( and no not you impulsive thats a different kind of tranny) for some time now. i think its a great idea gm co develops so many products with all the other manufactures it only helps all of us as it spreads the r & d costs across several madels and companies.
