1st reports on the new 2015 GM p/u's

I rode in a new 1500 GMC last week and the one thing I noticed right away was the truck was very quiet. I asked him how it tows his boat compared to his previous 04 F150 with the 5.4 and his response was his new truck tows a lot better.

One negative I noticed was the leather seats seamed a bit too firm for me, which is usually opposite for GM's plush soft seats of the past.

I can't believe GM won't put the 6.2L in the 2500's. Thnx

I thought for 2015 they were. I just traded my 06 Durmax for a 6.4 Hemi and was disappointed I couldn't get the new Chevy 6.2. I thought the dealer told me it was coming in the 2015 models but I could be wrong.

That looks like a super nice setup. IMO, the 6.0 is a total dog and not worth anyone's time but I tend to get a lot of flames for saying that.

The 6.2 will not pass the HD rating because of the aluminum block so it will never go into the 2500s or the 3500s in it's current form.

I am extremely happy with my 2012 6.0 2500HD Chevy. I read that there is very little difference in the chassis, engine and drive train for the 2011 - 2015 Chevy 6.0 2500 HD. I do not want an aluminum block engine in my HD truck and I don't need a diesel.

2015 GM HD trucks use carryover engines/trans.

The 6.2L is all aluminum and I would be surprised if it ever makes it into the HD. I expect GM to use the same tricks, or design/tech, on the current 6.0L as they used on the 2014 5.3L and 6.2L in half tons to bump power by about 15%.

GM's 6.0L has had the lowest power output of the HD gas trucks since it launched in 2007.5. Ford had the V10, then 6.2L. Ram the 5.7L and now 6.4L. Despite this, all comparison tests show it is still competitive. It is nearly bulletproof, cheap to maintain, and reasonable on fuel.

I'm glad it is just your opinion. My first hand experience as a contractor is that the 6.0 has and is doing everything we ask of it without issue.

Well, I just bought another 6.0L "dog" because I liked the last one enough to buy it in the 2015. Course, I really like dogs too ... plenty of those in my life too. Loyal, faithful, easy to feed, love you and protect you, and take it any where you want to go ... but, of course, that's just me and my dogs.

All you have to do is look at the gas SD/HD empty and towing comparisons and you will see that there still is no real "standout" in performance or mileage, regardless of advertised #'s. Just a slight variation in gear ratios will make one or the other have a slight advantage in a particular situation. It's nothing like the difference between the ecoboost and base V8's where it just dominates in towing performance and more importantly desirable towing characteristics.

The problem is the eco-boost gets no better gas mileage just like you are saying. The new eco-diesel ram has the most potential in my opinion. Chevrolet is coming out with one next year as well. I think you will see more of that in the future.

The Eco-diesel needs more payload before it can become a viable tow vehicle for most trailers. I agree about potential though.
