"Well, I have 2200 miles on my Tahoe H 4X4. It replaced a Ford Excursion Diesel 4X4. This thing gets way better mileage!"
 
Your Tahoe is about 1000 lbs less than the Ford, and has a smaller engine. What was the tow rating on the Ford vs. the Chevy? My point is that it isn't just hybridization - it is mass, wind cross section, and engine size that makes for different MPG at the same MPH.
 
Did you ever draft with your Ford?

Most dealers are offering about a $10,000.00 discount off of the MSRP. I have even seen an east coast dealer offering almost $15,000.00 off for a demo with 800 miles. I think its time to replace my wife's 1998 Suburban with a new 2008 Hybrid Tahoe.

I took delivery Aug 30 2008, of my 2008 GMC Yukon Hybrid with dvd rear entertainment etc. Stickered for 53k but I paid 43k and dealer threw in Ego Look Bluetooth device installed. I expect to also get 2200 from IRS tax credit. All reviews of vehicle assume paying MSRP and gas at $2.80 -$3.30 a gallon. Well at my net purchase price of 40.8k and gas at 3.80 a gallon what is the economic viability? Yes you can get a similarly equipped Yukon non hybrid for 40k net after GM employee pricing but you wont get the IRS tax credit. So the price is nearly the same net to the consumer for the Hybrid, but you will enjoy better mileage, lower operating costs while only giving up a power rear hatch and potentially captains chairs in the 2nd row. This seems like a no brainer, win win equation in favor of the Hybrid correct? Is there something I am overlooking?

2003 Tahoe with irratic locking system by jbowenstella

Recently, while driving, my door locks unlocked and then relocked without being envoked manually. This has occurred several time at different speeds while accelerating and decelerating. On occasion, the air conditioning system is turned off. On two occasions, the engine cut out. This obviously is of most concern to me as the steering wheel locked up. To recover, I quickly placed the transmission in neutral and restarted the engine. I took my Tahoe into the Chevy dealer but the mechanics were unable to find the source of the problem after running the diagnostics. I was certain that this was related to a falty computer chip. Now, I am at a loss for what is causing the locking system to operate unprovoked. Has anyone else experienced this dilemma? Thanks for you input in advance.

if what you say is true (i.e. the hybrid and non hybrid costs about the same) then yes, it's a no brainer with the tax credit and better milege.
 
but I have a hard time believing the hybrid version of the Tahoe can be had for only a extra $1,000.

2002 Tahoe Hybrid by pappysway

I drive a 2002 Tahoe with 5.3 Litre engine and installed a Hydrogen Hybrid Upgrade System and getting about 5 mpg better now. I'm thinking about maybe installing another one or two units for even better mileage. I like my Ho and really can't see dropping the $60K or so for the new Hybrid, especially when I already have one that's paid for and suits me well. It's got over 132'000 miles and is well cared for. The hydrogen installation wasn't that difficult. The toughest part was finding a good place to mount the hydrogen generators, I put on two generators up in the bumper. There is a lot of space there and the hydrogen generators fit like it was made for it. The system came from THOR. They have a website www.kickgasgohydrogen.com. check it out, I got the CombiPak.1.S. It cost about $900 including two of the hydrogen generators and shipping. Those guys are very helpful, they answer email and the telephone and answered all my questions while I installed it. The hydrogen seems to give it more power too.

I know that it has been a long time since your post, but curious if you ever reconciled your issues with the gas mileage? I just purchase a 2008 4X4 Yukon Hybrid and have been averaging only 16 mpg on 3,550 miles. Short of getting rammed in the rear for driving so slowly, my wife and I have tried everything to get the mileage to go up. Took it to the dealer, they said everything was running fine. Then, they stated that the sticker says that "depending upon driving conditions it should get between 16 and 24 mpg. Proceeded to tell me that my gas mileage was within those parameters. They also told me that their salesmen vehicles were getting the 20/20 as advertised. I asked to go out and look at one. While there, I asked them to turn on the computer and guess what - 13 mpg!! Contacted GM and they wanted nothing to do with me. I'm convinced GM's Hybrid technology is a scam. Curious to see how yours is doing? Thanks!

2008 Yukon Hybrid Gas Mileage by concerned10

I have a 2008 Yukon Hybrid with approximately 3,550 miles on it Driving the vehicle under normal conditions, not tearing it up by any means, we average only 16 mpg, or less. My wife and I have tried everything, short of causing pile-ups behind us by driving slowly enough to stay between the green while entering freeways. I am anxious to hear from other owners out there to see if I have the only bad one out there, or if this is the norm. I contacted GM and the dealer and they told me that it was operating normally because it falls within the 16-24 estimated mileage according to the EPA. A regular Yukon will get better than 16 on average. As it stands, I would not consider this vehicle if you are looking! Call me first.

I kept mileage logs on every tank of gas for the first 6400 miles and the average was 17.4 mpg. I quit logging the tanks partly out of frustration with the numbers but mainly due to my wife was filling up the tank without resetting and writing down the mileage. I now have ~12000 miles, and have noticed that my averages (based on the on board computer) have been ~19.5. It would be interesting to know what kind of driving you are primarily doing. My "in town" driving is the majority of what I do. Lots of stop and starts, rarely over 45 mpg, usually around 35. I really think that under 35 stop and go is kryptonite for this truck, and all trucks. I agree with you, I would not buy the hybrid again. The mileage improvement is nice and considerable, when compared to a Denali which I would have otherwise gotten. It is quieter and seems to ride smoother. However, the lack of spare tire, power liftgate, and poor design of the second row seats when folded forward annoy me. Furthermore, I'm not impressed with instantaneous throttle response. Yes, when you get the engine revving and are accelerating at mid to 3/4 throttle, the torque resembles a diesel in feeling, but when pulling into traffic or merging and you need that instant grunt, it responds slowly. To that end, I have told my dealer that if a comparable Denali comes in as a trade with similar miles and we can swap, to call me.
 
I will say that I think my mileage improved after those 6200 miles when I stopped caring about the economy gauge. Flip the trip computer to show the instant economy, and when accelerating, get to speed quickly, then maintain a constant speed, and try to keep the instant gauge in the 20s. Logic says accelerate slowly, but this truck weighs A LOT, and getting it to speed uses a lot of gas whether the electric is helping or not. The major savings to improve average MPG IMHO, come from steady speed driving at moderate speeds (40-65 mph).
 
BTW, My 80-85 mph averages have been around 18.5mpg. My Dad's (2007 Denali) 80-84 mph are about 16.0mpg.
