I have a 2012 2WD Silverado 1500LT crew cab short box and I tow a 5,500 center console boat between Ohio and Florida. Anybody got an opinion on how much better the 3.0 Duramax will handle this load. The 5.3L does ok, lots of RPM and less than 9MPG. I read where the 6.2L has the same upcharge as the 3.0

Thanks
Niles

From the reports I have seen and read, the 3.0 does pretty good for itself. It won't have near the get up as the 6.2 does off the line, but from all accounts it drive similar to the 5.3, but with more grunt down low, which is generally where the diesel shines, and also why you will almost always get better mpg while towing with a diesel.

With it being so new still, longevity would be the main point of contention for me. But besides that, it seems to be a pretty decent motor so far besides for a couple introductory issues like everything will have.

I still am wanting to drive one to see how they are first hand. Then I'm really eager to see what tuning comes out for them.

the 6.2L Diesel is a $10,000 upgrade charge,...
the 3.0L Diesel is a $2700 upgrade charge.
….
if you think back 10 to 15 years ago, the Powerstroke & Duramax 6L engines made about 500ft/lbs of torque, now that's what the 3L diesels are close to making!

I now have 2000 miles, and I towed a 5000lb trailer. I LOVE IT. the torque is plentiful, and smooth. it is very easy to speed in this diesel vehicle...

I was at the dealership about a month ago and while mine was getting an oil change I took a 3.0 Duramax for a little shake . To say I was impressed was an understatement. I was merging onto the highway under normal to me acceleration, looked down and I was flirting with 90. I'm pretty sure it would outrun my truck all day long. I can only imagine it tows very well also, and I'd venture to say you'd do much better than 9 mpg.

You only need to drive one to love it. It's night and day power over the 5.3. Steady pull at low rpms. The 5.3 (and the 6.2) have to really wind up to pull. The diesel option is about the same cost as the 6.2. I would think if you do any amount of miles the fuel economy would be a plus. Mine is doing amazingly well on fuel even though I haven't gone on any long trips yet. Time will tell how the reliability will be, so far I'm hearing of some CEL codes being set but the gassers doesn't that too.

Happy Holidays to you too! Yes you will really enjoy the Duramax compared to the 5.3. So much more power. Low rpm pull. Enjoy it!

Duramax,... I LOVE the Torque and the feeling of acceleration right away off idle. GOOBERS full of torque.
I was constantly spinning the rear tires in 2 wheel drive. I have put the truck into the AUTO all wheel drive mode, and it accelerates like crazy all the time, going around turns and when raining.
My foot is on it constantly, it is so addicting and fun to drive.

Who would have thought they could pull that much power out of three litters. They did a good job on this. Now as long as they hold up.

The 3.0 it's a VM Italian engine ,Specialist in diesel Engines from 40 years .
you just discover from some years that truck ,should be Diesel like in the rest of the world .
you can trust VM with Fiat it's leader in diesel Engine ,don't forget that Diesel common Rail was invented from Fiat .
In Italy we have a 1.3 liters about 100 HP and 80 Miles gallon.
I want say that 3.0 TD VM have more torque at 1000 RPM that 6.2 Liters Gas. Compare the graphics of torque around 1000 to 2000 Rpm .
Diesel win ,to me towing want Diesel .
That particular Engine it's also used on cars like Alfa Romeo ,Maserati ,Fiat ,Jeep ,Dodge .
Merry christmas

The upcharge for the 3.0L was reduced during the fall.

Currently it is priced between the 5.3L and 6.2L.

As others posted the 6.6L duramax is only available in the 2500/3500 (they have the new 6.6L gas as standard)

The 1500's have 2.7L I4 turbo, 4.3L V6, 2 different 5.3L V8's, the 6.2L V8, and the 3.0L I6 diesel.

I just pulled the trigger on a '21 3.0 Silverado LTZ CC 4x4 on Monday. So far the only concern I've heard about is the belt driven oil pump. Maintainance schedule calls for a belt change at 150k miles. Gonna be some heavy labor charges since they have to pull the transmission to get to the belt. I haven't heard of any pump failures.
Pricing on the 3.0 option varies with the trim level the engine is available in. The option on the LTZ I ordered was less than $1000. I'm looking forward to it!!
I don't think the 3.0 is a VM engine. I do know that the Colorado/Canyon 2.8 diesel, (my trade in vehicle), had it's roots in the VM design sans the "Tunnel Crank". Any more on this?

The 3.0L V6, found in Ram trucks is a VM Motori designed and built engine. I had a 2017 Ram with that engine, pretty capable truck.

The 3.0L Duramax in my 2021 GMC is designed and built by GM and has definitely more power then my Ram EcoDiesel had which had a GDE tune. The Ram got better fuel mileage though, my current truck averaged about 23 MPG over the first 1000 miles.

Duramax 3.0: designed and built by GM in the US.
Powerstroke 3.0: British Ford/Peugeot design and built in the UK.
EccDiesel 3.0: VM Motori designed and built in Italy.

You can see EcoDiesel Rams and Duramax GMs around where I live. Never even seen a F-150 Powerstroke at the dealer, I don't think they sell to many of them.

Wait: Member nwaring was asking about the price of the 6.2 Gas engine opposed to the 3.0 Diesel, in the new generation trucks. Which they are roughly the same price.

There is no 6.2 Diesel in the new generation Silverado. The old 6.2 Diesel was a V-8 Diesel. completely different.

The new 6.2 gas engine is a real performer.

Over the 5.3, the 6.2L is about $2495
Over the 5.3, the 3.0L is about $ 995

I'm starting to wonder if this will become an orphan engine soon--I was about to pull the trigger on a 3.0 until I read about the 150K replacement which on my 4x4 would have meant dropping xfer case and transmission. Kinda gives the lie to "Dura"max--you say "Diesel" and you think over 300K easily. But after a bit of thought I warmed up to the idea and was about to call the dealer when I saw that 3.0 production is halted due supply chain issues. Which made me wonder if, given that they're already reducing the price on it, there's this huge 4-figure mandatory maintenance that is maybe 2-3 years down the road for some users, and they've stopped producing them indefinitely, Chevy just might decide this niche motor isn't worth supporting..... On the other hand, maybe they'll use the break to get better solution on the belt and give buyers the confidence they need that there is durability still in Duramax?
