Denali vs Yukon by lobsenza

The major differneces are all wheel drive, more powerful engine, and 6 speed automatic. The 6 speed auto should improve power and economy. I think the autoride should be the smae in both vehicles. Make sure the tire pressure is the same when comparing them.

1) AFM probably won't be active very much, if at all, for heavy-footed drivers. That doesn't mean the fuel economy results won't be better, just that the AFM only kicks on with extremely light throttle application. Lots of discussion around the internet on this technology and most owners' lack of enthusiasm. Most say it just doesn't work. (works fine for me with my 07 Av 5.3l 4.10 rear end 4 speed auto, but it could probably still engage more often than it does). One or two mpg difference is really so small a cost difference (even for an entire year's driving at ~$3/gallon) that I wouldn't worry about it. Now 4-5 mpg difference is a whole 'nother ballgame..
2) No input. My LTZ has the autoride, and I like it much better than the other non-autoride Avs I've tried. The single Yukon I test drove felt about the same as my Av though (top-of-the-line dealer demo back in February / March of last year).
3) The 4wd systems have a 4WD Auto setting. This'll let the truck decide whether / when to engage all four wheels because of slippery roads, but at the cost of a bit of fuel economy. I've had this particular 4wd system on each of the 3 GM truck / ute's I've owned so far, and it's been great with all of them (03 Trailblazer, 04 Silverado, 07 Avalanche). The real advantage in my opinion is that you can set the system to 2Hi when not needed (doubt you'll have much concern of slippin' 'n slidin' in the middle of June!). That is supposedly up to 5% better on fuel economy that when running in A4WD mode, even without ever having all four wheels kick in. This is simply because there're more drivetrain components turning in A4WD mode (ALL the time).
However (big one), as pointed out above, the six speed tranny is only available in certain vehicles and with certain engines (I believe ONLY 6.2L vehicles at the moment). That could be a good equalizer, as well as providing a little bit better feeling 'power / throttle responsiveness' thanks to having more options of which gear to be in in a given situation.
3) I'd doubt there's that much difference. Other than that you have to decide to run in A4WD / 4Hi / 4Lo with the 4WD system, while the AWD is always on the job. (I'd go in A4WD and it'd be pretty much just as moot). Also, if you can't get around with the 4WD system, the AWD system is pretty much guaranteed to do no better.
4) Yep. My wife's 05 Terraza has the ability to play CD / MP3 CD up front while the kids watch their DVD movie in the rear, thanks to the DVD slot being *in* the overhead dropdown. NONE of the GM 900s have this setup (strange). Instead, DVD capable units use the same slot for ALL CD / DVD / MP3 CD media. Even the NAV system, which has two slots. The second slot on these is behind the screen, and is a dedicated Nav-DVD slot (not capable of playing CDs or DVDs).
5) OnStar combined with Verizon. Can't say. I pay for the OnStar and the phone minutes, but haven't even considered linking it to my Verizon account. I move around too often to guarantee that my cell provider will remain Verizon anyway.
6) My Avalanche fits nicely in the current guarage with maybe 3 feet excess total front and rear, even *after* I set up a ~2' deep workbench at the rear of the garage. But I think the builders went supersized on this guarage (too bad I rent and plan to move to IL eventually- this garage is my favorite part of this house). Heck, my 04 Silverado extended cab standard box (6'5") fit with inches to spare. I'm not sure what's considered a "standard" size garage, but I'd always heard that GM engineered the Suburban (Yukon XL) to be just short enough to fit in one lengthwise. If that's true, I doubt the liftgate would open with the garage door closed, and even with the door open you'd need to pull in so the gate opens through the garage opening.
 
Final thoughts- I love my Avalanche. But if I were going mainly for people friendly family hauling SUVs (including the dog), I'd be seriously considering those Lambdas that you marked off your list. All the carrying capacity (or 9/10s anyway) of the 'burb and its twins (definitely a bit better packaged than the Tahoe), with decent towing at ~5000 pounds (where the Tahoe'd win my decision if I need MORE towing), better highway fuel economy (enough that I'd consider it significant), and in general, very up-to-date-all-around platforms. If my wife ever trades her van off, one of those will be the replacement. (The Avalanche stays- I NEED the extra towing capacity, plus the flexibility of being a standard pickup / long box or a crew cab / short box at the spur of a moment puts it over the top).

Glad I could help. I'm personally debating whether I like the look and concealed storage ability of the woodgrain inserts enough more to justify the loss of actual space and utility of the black insert (w/CD slots, etc.). Somewhere down the line I'll probably replace the speakers too, and the Bose subwoofer is something that'll most likely be high on the hitlist, if I can find something that fits where it does but performs better..

1. I think the AFM is a great Idea but I've got to admit, I think they implemented it wrong. They default it to V8 unless it doesn't need the power... I think they should've defaulted it to V4 unless it does need the power. I think it would be way better if the truck Idled in V4 rather than V8, plus I often notice that when coasting downhill the truck stays in V8 mode, this obviously uses twice the gas than V4 mode. The one think I noticed is that if I let the car control the speed then everything works a little better. I use cruise control as much as possible... My daily driving I average about 15mpg, but on the weekends when I am in better conditions I've had my Tahoe up in the 18-19 mpg.
5. I think the cost of Onstar is way too high... the only thing I find of value is the montly email that they send. Plus I'd like to be able to use the red button in an emergency... Is that work $200 a year, I don't think so.. I emailed Onstar suggesting a more basic plan, but unless others do as well its going to stay expensive and I will never pay that price just for a monthly email and 911 services that are already on my cell phone.

My thoughts on your #6:
 
I have a 2005 Yukon XL which is 219.3". The 2007 is a bit longer at 222.4". I think the standard garage size is 20'x20', or 240", so there ought to be room to spare. I can fit mine in the garage with space to walk around the back - not a lot, but enough. The garage door must be up to open the tailgate (I've put some foam insulation along the bottom edge of the garage door, so it doesn't scratch the paint). But, I can lift just the rear glass with the garage door closed, which is fine if you're tall enough to reach in.
 
I am a big fan of the XL length. Our third row is in use every day, so we truly need the extra cargo space. Got three growing boys, so a week's worth of groceries pretty much fills it up! As for the dog, I really believe using a kennel/crate is much safer. Depends on how big your dog is, of course. Plus it keeps the fur and slobber from getting everywhere. Our plastic travel kennel is pretty big, we can put both dogs in there together (one beagle and one shepherd mix mutt), and it fits very easily. As for luggage, there are roof top carriers and platforms that attach to the trailer hitch. You could even buy a small utility trailer with the extra money saved, looks like about $3K more for XL versus regular Yukon. But I like being able to fit everything inside for a weekend camping trip.

Thanks to all who have commented on my questions; the insight is indeed very useful! I will probably decide this week but am glad I didn't decide Saturday, as I came home and found a coupon in my mail for $1500 off a Yukon! That's a good bit better than the usual coupons I get in the mail!
 
The dealer said he would let me take home an XL for a night to see how it fit in my garage, etc so that will be helpful. I think I'll decide to get by with the regular length, though. By the time we add our bicycles on the back of an XL we would have a lot of length to deal with parking, etc.
 
Roof racks/trailers are pretty easy to add for the occasional family trip.

Regarding #4...My 07 Sub is equipped with a single CD/MP3 jack and the rear entertainment package, no navigation. The 6 disc changer is removed and replaced with a single CD when the rear ent is ordered. If the kids are watching a DVD through the stereo I cannot listen to a CD because the movie is coming through the speakers. However, if they are watching a DVD using the headphones I can listen to a CD, MP3 or the radio. There are two slots on the dash in this configuration, one for the DVD up top and one for the CD below. Not sure how it works if navigation is ordered. Hope this helps.

The Nav system is very similar. Also, I understand that there can be three different listening experiences going on at the same time. I've not tested it but from what I have read the Speakers can play one audio source, the wireless headphones another audio source and then the wired headphones a third audio source.
 
With the NAV system the second disk slot is behind the NAV screen and the NAV disk is usually kept there.

Fuel low, but not really... by mrowl1

Had a strange problem over the weekend. When I got in the Yukon, I knew that there was at least half a tank of gas.
 
But, within minutes, I am notified that I have low fuel, and the driving distance is low...
 
Thinking to myself, thats impossible...
 
And then, a few minutes later, it corrects itself. Shows that I have half a tank left...
 
Anyone else see this problem on the new models?

Thanks for the correction. I was under the understanding that the non-Nav RSE package didn't have two slots. Now I know better. My bad.
