And AFM.

No "Stop/Start" mentioned, but what's wrong with that, reliability?

IMO stop/start needs a bit more fine tuning in terms of smoothness and transition. Its still in the "some people notice it" vs. "I don't even know its there" phase. I also find it to be an ironic system. Shut the car off at a light to save gas, yet there is probably almost as much fuel used restarting that car vs. idling it for a bit at a light.

Well here we go beating a dead horse on a thread that saw it's last post in Aug 16 but here we go....I ordered a Denali to replace my 2015 SLT, as we now know, no ten speed but it will have the eight speed and LGZ V6. There does not seem to be anyone raving about the exceptional gas mileage this combination is getting, my current V6 and 6 speed give 24.9 on a very regular basis so the new combination already has a challenge. I will receive the truck in a couple of weeks depending on the speed of the engine pulling my personal railcar.

I do wish to report my 2015 is about the best GM pickup that I have owned, a couple of round trips to Texas hog hunting (4400 mi round trip) have been easy drives due to the comfort and roadability of the Canyon. I usually have it loaded with rifles, pistols and ammo along with my Texas buddy who flys to my place and we, along with my Westie, drive the trip together.....retirement does have it's advantages.

So this year will be the comparison between the SLT and new Denali.

Keep us posted......I think the 8speed is "Rock Solid" the programming is off? Hopefully it's spot on for the new V'6 if I was not married and car seats etc. I would be all over this combo or Diesel.......I think the Trucks are perfect in size for my needs and parking would be a breeze!

Mookdoc6, Of all the vehicles i have had over the years (except my 55's) I am more excited about receiving this Canyon than all those before it. I have not an explaination as the truck will not be that different than my current 2015 SLT loaded with accessories. I am expecting great changes in mileage hopefully for the good, i tend to be quite easy on the gas pedal, hopefullu the truck will cooperate with my projections and beat EPA projections. Will report on my first weeks in the Denali in a few weeks.

With these new 8, 9, 10 etc speed transmissions I really don't see the need for AFM. The trucks barely used it now and they have 6 spd transmissions. How the hell will you ever see 4 cylinder mode when your in 9th gear unless your going down a huge hill with a tail wind. Talk about stupid.

DarylZ71.. you're right... I have a new 2017 3.6 liter 8 speed... I do see the 4 cyl. mode kick in from time to time.. but you almost have to be coasting to see it. If you are on a completely level road you will see the 4 cyl mode activate, but the SLIGHTEST application of throttle (and I mean slightest...) the V6 is back on.

It would be nice to have that feature user defined. For example if you did almost all highway miles you may want the 4 cyl mode to kick in sooner and stay on longer to maximize fuel.. If you do a fair amount of towing you might want the 4cyl mode to not come on at all. I"m sure it's just a slight software change that would handle the activation/deactivation.
