2017 Gas 2500 Changes

SouthpawHD · August 14, 2016

They would dedign a hd version like Dodge did with the 6.4. Im going to watch this like a haek, getting hd gasser next time.

It is my understanding that the 6.4L Hemi in the HD trucks is not the same 6.4L in the SRT Dodge cars.

So if the 6.2L were to be used, many changes would likely need to be made.

Correct! Many changes were made to the 6.4, loads would be made to the 6.2. I hope no afm is used.

Was hoping for a bump in torque for the 6.0. I wouldn't mind about 450 :-D

GMC & Chevy websites only have 2017 1500s for build your own right now. Stop being slow GM lol

Sheesh, that blows. Been waiting year, after year for a gas upgrade.

I knew GM wouldnt use the 6.2 in its current form, but was hoping for an all iron derivative.

Same here. Was really hoping for an upgrade this year. Not sure I can wait until MY2018. As much as I hate to say it, I may be test driving a new Ford F250 6.2 gasser....

Well, since the L96 6.0L continues without any changes, maybe we will see an additional gas engine option for the HD's in the future. Could be GM doesn't want another engine option to steel the new Duramax's thunder at introduction.

Good Point ...

also - Do the true HD work truck users really want a gasser with more HP & Torque ? At this point GM say "not really". (and usually more HP = more gas consumption = not a good selling point)

The 6.0 is one of their best products for longevity, performance, and economy - they are being very careful not to mess up a good thing ... A new lemon engine could really do some irreparable damage to their the market share ... be it gas or diesel.

Yeah, there is a substantial difference between what Joe Sixpack wants in a pickup and what commercial users want. And considering that the lion's share of the HD pickup market is commercial users, Joe is not going to get all he desires.

The ideal situation would be like the commercial heavy truck OEM's do... they allow the customer to spec not only engine choice, but power levels also. And a variety of transmission options also. And the buyer gets to select the rear end ratio of their choice. Now granted, times between order and build can stretch out depending on specs, but you end up with the truck you actually want. No having to spend a bunch of money on aftermarket stuff.

We buy 6.0 gas trucks for our business and the motors are great..The one area they have fallen short is transmission longevity. We have put tranny's in just about every truck at around 120k. They have been maintained very well but have still failed. On the flip side we still have a 2005 DMAX/Allision that is all original with 500k on it. I wish they would offer the Allision with the gas motor.

I think it would pull too much power from a 6.0 honestly. Kind of like the discussion either in this thread or another how Ford has the torqshift trans hooked to their 6.2 HD pickups. It's a great transmission but it robs too much power from that motor and feels so sluggish. Apparently they have started to put a beefed up version of the f150's 6 speed into it now. Which leads me to say... BRING BACK THE 8.1 AND ALLISON COMBO!! lol

You are spot-on about the heavy duty transmissions stealing power from a gasser. I'm sure Ford is doing that because they have once again beefed up the trans for the Diesel preparing for the 1000 lb/ft thats sure to come very soon. A gasser would get most of its power robbed by the heavier transmissions.

My bet is the 6.2 Ford with 430 lb/ft and the new gas-only spec trans, and lighter weight will out power the 6.0 by a noticeable amount.

I think you are right, the Allison would draw too much power from the 6.0L. Incidentally, UPS uses a Freightliner chassis under their newer 'package cars', and it uses a L96 6.0L with an Allison transmission. Probably wouldn't be a good combination for a pickup truck, and great for constant stop-and-go 19,000# van.

Didn't know that. I'll have to ask the mechanics what's behind our engines here. I haven't looked at the gross of the bigger package cars, I'll have see if I can find those stickers tonight too. Funny how tradition keeps them being called package cars when they've been trucks for decades. Yet our all metal golf carts are "Power Industrial Trucks" even though we call them mules.

Can't imagine that the Allison has a major parasitic effect more than the 6L90 does. If it does, it has been poorly designed. The only appreciable difference is the amount of torque it can handle, and do so at lower engine RPM's to match up more to where diesels operate for effective power. It does have nice braking features on downgrades, but that has nothing to do with parasitic power loss. And probably the best reason why GM doesn't have a Allison option for the 6.0L has more to do with cost difference in transmissions and the number of potential buyers that would feel the need to shell out more money for it. I am sure they have done their cost analysis studies. I would jump at a 6.0L / Allison combo.
