That's not out yet as far as I've been able to determine. Honestly I'm not expecting more than 1 or 2 mpg increase. It's still an almost 3 ton brick. I am expecting a much better driving experience though. What I've read about the new 8 speed transmission leads me to think that it's going to be much more responsive.

I just spoke with the local GMC dealer and they have the new ordering info for the 2015 1/2 ton. With the Max Tow and 6.2 with 3.42 on 4x4 you can now go from 7200 to 7600lb GVW. Should help the payload.

I assume that's for the pickup. The Yukon Denalis are coming with the 3.23 gearing and, in 4x4 Denali trim, have a GVWR of 7500lbs and a payload capacity of 1492lbs. The non-Denali trim has the same GVWR and a payload capacity of 1606lbs. Obviously, the door sticker on the vehicle controls as it takes into account that specific vehicle's options.

Correct, yes, the pickup.

OK, hold those thoughts. What about the Cadillac Escalade ESV, or whatever they call the Suberban sized unit?

I've been to the Cadillac website, as well as Edmunds, and they don't say much about axle ratios or tranmissions, or towing weights, but I'm thinking they should offer one similar to GMC for towing.

Can you still order these things and spec them out like you used to?

Yes you can. The Eski and Denali should be the same. The site I go to has not been updated with the interim model information yet so I'm with you; I'd like to know more about the 2015I and where I can find the spec sheet for them.

That would be so cool. I could be happy with the Denali, but I really like the Caddy.

Thanks for the link ph, I'm going to save it.
I noticed that the 5.3l and 6.2l vehicles have about the same tow ratings, different rear gear ratios however. I would have thought that the powerful 6.2l engine would have a higher rating?
I also noticed that the Chevy Tahoe information has not been updated only GMC and Caddy

I had a feeling this 12000# rating might be inaccurate. First, usually the SUVs from a manufacturer are rated less than a truck from the same manufacturer. Second, what has changed since last year to justify this sharp increase in tow ratings?

2015 GMC Yukon Denali 12,000 lb Towing
 

I think the Tahoe hasn't been updated because the powertrain hasn't changed. The Yukon Denali and Escalade have the new 8speed transmission so the numbers changed a little.

If I had to guess I would say that the improved fuel economy of pairing the 8 speed with the 3.23 gearing was considered more important than potentially increased tow ratings by sticking with the 3.42 gearing. Honestly, without a suspension upgrade to handle the extra tongue weight, added towing capacity probably wouldn't be useable.

I read that the Tahoe LTZ would be the only model that would get the 8spd of the Chevy line up.
In other words only the high end models would get the new transmissions at first. Maybe someone at GM changed their minds?

For 2015 the only vehicles getting the 8 speed are ones with the 6.2 liter. I'm assuming the 8 speed will eventually cover the whole engine line. It's the same progression they used with the 6 speed rollout. If I were to guess I'd say we'll see 2016s around the middle of next year with the 5.3 and the 8 speed but it could be longer.

GMC has updated its website with information on the 2015i model.

Looks as though fuel economy remains unchanged. Oh well. I was hopeful it would be better but I'm not overly upset about it as I was only really expecting 1 or 2 mpg increase.

Cool so which one did you order? 2 or 4 wheel drive?
Color? Wheel size?
What can I say, I'm curious.

I ordered Silver with Coca/Dark Atmosphere interior. XL, 4wd. Standard 20" wheels. I really like the look of the 22" wheel option but several of the reviews I read noted a harsher ride with the thinner rubber. I opted for cushier.

Otherwise it's pretty loaded with the open road and luxury packages.

Sweet!
I just upgraded to 22 inch wheels from the 2015 model Tahoe, it had 20s. I honestly can't tell any difference.

Those are some slick looking wheels! I may end up doing an upgrade later. Given that they didn't need to be factory installed I figured I'd wait.

Newbie here

We're just starting to investigate so a little help would be appreciated

Never towed anything but a root tiller before
Looking at 19-26' air range, but also need a tow vehicle

Unless the consensus is gm's rigs are inferior to ford and dodge, I'm
going to get a chevy or gmc since I've got a couple thousand bucks accumulated on my gm card

So with this new tranny (which will be paired with a 6.2 v-8?) will it be enough to tow a wet weight 25-26 footer?

Will it be too much torque, someone bent their frame or axle?

We live in Bay Area so everywhere we go involves scaling some steep mountains Want enough giddy up so I can do at least 60 mph uphill

Truck or SUV? Make any difference as towing rig?

Anything highly recommended I should get factory installed, special brakes,
type of tow package, type of tires, other options or accessories?

Thanks for input

I would not be surprised if the Caddy version has less payload due to all the "glitz" items.
