click above image for new pics of the 2008 Chevy Tahoe Hybrid

Finally! For months and months we've been hearing that the upcoming two-mode hybrid SUVs from General Motors will have better fuel economy by this or that percent. Today we learned from Automotive News exactly how much better they'll be. The 2WD version of the Tahoe and Yukon Hybrids will achieve 21 mpg in the city and 22 mpg on the highway, while the 4WD version will get 20 mpg in the city and 20 mpg on the highway. For comparison's sake, the 2008 Chevy Tahoe 2WD gets 14 mpg city and 20 mpg highway from its 5.3L V8.

We had a chance to drive GM's pair of two-mode hybrids recently, and we're pretty amazed at just how normal they felt. Since they are true hybrids, both will pull away from stop on pure electric power, which is a bit eery at first. Mash the throttle, however, and you'll be extremely surprised at how fast these hybrids accelerate. Their two-mode hybrid system is mated to a 6.0L V8, which, in combination with an assist from the electric motor, can really move these SUVs down the road. Together they produce 332 HP and 367 ft-lbs. of torque, which also allows for a 6,200 lbs. towing capacity!

GM also spent a lot of time and money reducing their weight by adding an aluminum hood and rear hatch, lightweight wheels, and thinner seats. In fact, we've heard reports that a Tahoe Hybrid will weigh exactly the same as a regular Tahoe, despite the addition of the two-mode system and battery pack, the latter of which is hidden underneath the second-row seats. That's nothing short of amazing.

Of course, the two-mode hybrid system, weight savings and aerodynamic improvements must add a lot of cost to each GMT900 two-mode hybrid. You'd think so, but wouldn't be able to tell based on what GM will charge you for one. The base Chevy Tahoe LS starts at $34,000, while an upper level LTZ model begins at $45,510. Automotive News is reporting that the hybrid versions will start in the low- to mid-$40,000 range, a price we've corroborated with some inside sources who also tell us that the additional to cost to make these vehicles well exceeds what GM will charge for it.

We'll find out more details soon enough, as the Tahoe and Yukon Hybrids will officially debut tomorrow at the Texas State Fair.

      Folks sometimes miss the point. next time you are sitting in a traffic jam (something the EPA does not measure) for an hour, surrounded by hundreds of trucks, listen to the silence. It is the sound of no fuel being burned. LA (the biggest traffic jam in the world) will save billions of dolalrs in fuel costs.

      "Anything you read in Consumers Report, J.D. Power, or even Lemon-Aide has very little credibility in comparison to hundreds of people's real life experiences. "

      Wow-SO everyone else is wrong-but a some people you know are right. Let me tell you thousands of people have real world experiences that contradict your "hundreds."

      Oh and millions of other people who think it's a great truck and continue to buy soooooooooo many are wrong. The buyers have spoken here.

      You are some piece of work-I'm happy to be in the vast majority of people who have it wrong-while your miniscule minority has it right.

      whofan, I understand that the weight is a major concern. Although 2 mpg for the price might not weigh out the cost for the wait of a future model.

      anyone know the price premium for the hybrid system?

      Good work GM! Very impressive.

      All that's left to do now is take a Tahoe Hybrid on a week long camping trip.

      I didn't bash CNG. If someone was marketing CNG vehicles on a mass public (not fleet) level, they'd be a great alternative.

      That said, I wouldn't argue that a Cavalier is, overall, as compelling a package as a Prius. I certainly don't think the public would be clamoring to get back behind the wheel of that circa-1995 design.

      If GM came out with an alt-fuel Cobalt or HHR, they'd be onto something (and I'd be no less enthusiastic about it than the Prius).

      If Toy could make a truck that was on par with any truck that GM makes, hybrid or otherwise, they would collectively cream their pants. There, fixed that erroneous statement for you, PJ and Random Task (you fight like a girl).

        Oh yes, Toyota better get off their asses and build a bigger truck to get into that market that's tanking. Brilliant.

      Hey Chuck U. Farlie how is that FJ Cruiser of yours holding up? Toyota quality at its finest, brand new FJ Cruisers structural fender pieces are cracking. LOL

      Comments like this are just ignornace.

      Do you buy anything that's made in China? If so you should print out this web page and eat your words, since they make absolute crap.

      So GM have developed a 6.0 V8 HYBRID with ONLY 332bhp, and ~20mpg consumption?!


      Most European manufacturers can build an engine with HALF the cc capacity of this GM behemoth, but with more bhp and torque combined with double the mpg!

      You have the technology and ability to build much better vehicles than this GM monster, but with fuel costs as low as they are in the U.S. there seems little incentive to do so.

      I guess the current and next administration will keep plundering the globe for resources to fuel these guzzlers.

      When will the U.S. manufacturers learn that making cars as crap as this is as bad for the world as the rest of the U.S. population supersizing their McDonalds meals.

      I expect half of you need and use a Prius just to get to the refrigerator?

      According to Fueleconomy.gov the Rav4 4WD with a 4cly gets a combined 22 miles per gallon and the CRV gets the same. Cool. I cannot wait for applications of the system. Go GM.

      Towing capacity like a truck.
      Passenger capacity like a van.
      Safety like a tank.
      AND with the city fuel economy of a V-6 sedan.

      Great to see another rendition of the hybrid drivetrain improving the automotive landscape.

      We'll see what the real world numbers are. This sort of improvement sounds big, but let's face it, half of the people who buy huge SUVs will look at it and go "Hybrid? I ain't no treehugger" and ignore it.

        As someone who tows an RV with a mid-sized SUV and needs to carry 5, I can't wait for a vehicle like this that provides decent towing capacity and room of the Tahoe while getting such reasonable fuel economy.
