Replying to: juddsonr (Aug 02, 2008 7:55 am) My driving is divided evenly between in town driving (that uses more of the electricity) and short highway trips of about 6 miles. That may account for my higher average?

Replying to: juddsonr (Aug 04, 2008 3:53 pm) Yes, I do try to watch the economy meter although it is difficult. And, the mileage was higher at 20.9 when we went on a 3,000 mile trip which is 1/3 of my total mileage. That probably helped pull it up to the 20.2.

Replying to: dixienbailey (Aug 04, 2008 6:36 pm) What increase does the 20.5 mpg amount to over the non hybrid? thanks for the feedback |

I don't know what the difference would have been in my old Yukon if I had been more aware of stops and starts. But, having the "Economy Meter" certainly makes me more aware!

Replying to: dixienbailey (Aug 05, 2008 9:13 am) I'm a 2WD Yukon Hybrid, backseats stored in the garage, mainly driving alone with a light payload. For this tank, my computer gave me 18.4 mpg, but by my calculations, it was 17.9. My previous 4 tanks I recorded were 16.9. I know these are good numbers for the size of the vehicle and the type of driving I'm doing, but I really feel like I should be able to get 20 mpg mixed without "trying so hard". Could I have a "dud" hybrid system? Could there be some problems with my particular truck? Prior to buying this thing, I read every online review including the press introduction mileage contest. I truly feel GM put this vehicle on the market so that in normal day to day driving, you should achieve 20-21. In this last tank of gas, to stay in that solid green area of the economy gauge, it took a very deliberate driving style, which for me, was SO MUCH slower than I am used to. I felt like I was getting left behind in traffic (and I live in a retirement area where no one is in a hurry). Other owners--do you feel this way?

Well, I have 2200 miles on my Tahoe H 4X4. It replaced a Ford Excursion Diesel 4X4. This thing gets way better mileage! Disclosure: I also own and enjoy a Ferrari F430 Spyder, and Porsche 993 twin turbo. So, I'm not the most economical driver, if you get my drift. In any event, a recent 150 mile trip to Indy from NW Indy got me 23.8 indicated mpg! (I don't think I touched the brakes once on I65 portion of the trip, but stayed at about 65mph, which I think is a safe speed, and drafted off semi's.) Mixed driving, the indicator is showing 20.9 mpg right now. I don't vouch for the indicator, it was not that accurate on my Excursion, I suspect this one's pretty optimistic also? I should also add that when other family members or friends drive it, the mileage goes all to hell, like 17mpg, until I teach them how to drive safe yet economically. That being said, I think there's lots of truth to the point that you could just drive an ICE Tahoe gently, and it would get pretty good mileage, too. I find the acceleration of this vehicle to be plenty powerful when needed. I'm pretty happy with the car so far.......the fun of it is trying to keep that average mpg up. And, this is my only vehicle without a radar detector installed! Cool!! PS Wife drives a Jeep Cherokee with the hemi, best I ever got driving it on the same trip to Indy was 16mpg! It's mileage sux, city or highway. Tom D. in NW Indiana.

PPS, Instead of using the goofy analog needle "economy" gauge, just bring the digital average mpg gauge up, and pay close attention to it. Also, on starts, start out slowly so as not to engage the ICE as long as possible. I think that must be the real advantage of the hybrid system, wonder what % of energy is used for initial inertia in the average vehicle? (I was a physics minor in college, I suspect a lot.) So, try to get the vehicle rolling with no gas engine, battery only, before you kick in the gas engine to get up to speed. It takes a light foot, but it's fun. I'm able to run on battery only just about the whole mile in my small town on residential streets to my home. It's kind of a fun game, even have my 17 year old trying this. On the highway, use cruise control, at 63-65mph, you'll be amazed at the mileage you get! PS again, if you really wanna talk about lousy fuel economy, my boat gets 3 to 4 gallons to the mile, NOT miles to the gallon. Of course, it seats more than the Tahoe........... Tom D. |

Replying to: thomed (Aug 20, 2008 7:08 pm) 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. | |
