Payback for the hybrid premium in only TWO YEARS !!! That's super fast for a hybrid. Most take 4-7 years - so if GM can recoup the hybrid buyer's money in only two years that is a major advantage.
 
Edmunds says the Tahoe Hybrid will get 23 mpg:

Edmund's is dreaming if they think the Tahoe hybrid will get 23 MPG around town. Maybe 20 MPG. That would save about $750 per year for the average driver. Over 5 years pay back if it is only a $4k premium.
 
The whole program is riddled with IFs.

It can be riddled with 1000 gigantic IFs but when it returns higher mileage and thus burns less fuel and pollutes less than it's non-hybrid counterparts, then all the IFs will become non-issues.
 
GM will collect more interest on the higher-priced financing. That will help counter some if not all of the hybrid costs they are eating.

In addition to everything you talked about here, there is also another big IF. Yes, it will likely get 18.75-20mpg around town, but it remains to be seen if the "second mode" motor will kick in at a high enough speed to be useful at all. The first drive article on Edmunds says this:
 
  "Toward the 50-mph mark on steady stretches, cylinder deactivation imperceptibly changed the V8 into a V4."
 
I certainly hope that that doesn't mean it stops working after 50.
 
If GM hopes for this to make an impact in the real world, then it better work up to 70 or 75mph where many drive (and some drive a good deal faster than that). If not, the second mode is nothing more than marketing baloney.
 
These kinds of answers though will probably really only come when the thing starts rolling into production and buyers start showing on the lots.
 
My high hopes for this beast are kind of fading. It seems like details like this would be trumpeted if the news was good for GM, and good for customers.

Finally some good competiton for GM! by u045777

In page 2 of the the article above it says that the new 2009 Sequoia hybrid will be the Flagship of Toyota's line. Buyers will be able to choose either V6, V8, or Hybrid.
 
The size of the new Sequoia appears slightly bigger than the Tahoe but smaller than a Suburban.
 
I'm betting that the Sequoia Hybrid will blow the doors off the Tahoe Hybrid in MPGs and reliability.
 
Soon well have a choice: Tahoe Hybrid or Sequoia Hybrid! I can't wait

I would say it will have the same HSD that is in the LS600h. So figure at least $75,000 for the FLAGSHIP Sequoia. If you don't mind paying $30k premium for a hybrid as is the case with the LS600h go for it. Figure on less than the 21 MPG rating the LS600h has. A Sequoia that gets 19 MPG would be a 22% improvement. Don't expect it to match the Tahoe Hybrid mileage. It ain't gonna happen.

I'll agree with what you've said here - cost is going to be REALLY high on this model. As much as I'd love a full size suv that gets a combined 20mpg, I just think it costs too much. You take a vehicle that is a $40K ticket already and add another 10% to the price tag, plus all the added complexity which will likely translate to worse than average reilability. I think I'm going to stay away from this one.
 
Besides which, people are being mighty optomistic about the "projected" performance here. These things will not defy the laws of physics, and real world numbers are likely to come in below the predicted economy values.
 
Nope - I'm going to buy used next time and wait this product cycle out.

"I had a chance to test-drive the car. Read review here: "
 
Your statements about the Prius are incorrect. The electric motor assists the engine when needed at all speeds; it is never disconnected (unless the battery becomes depleted, which is a rare event, but in any case it is not designed to disengage the electric motors and run on ICE-only at higher speeds).
 
I haven't studied these full size GM setups, but if they truly have two electric motors, one for slow and one for fast speeds, they are really wasting space and weight. Usually "dual mode" means that the vehicle can run on electricity alone (while the battery lasts) or on combined electric/ICE.
