Do you think the Silverado/Sierra might ever have the 2.8L Duramax?

Just thinking out loud here but I did a quick google search and really didn't find much info on this but do you think the Silverado/Sierra might ever come with the 2.8L Duramax? The Duramax puts out 200HP and 370lb/ft of torque and that would be more than sufficient to move the truck around,that's the more power and more torque than the base 4.3 of yesteryear.

I imagine you could see in the 30mpg hwy with such a setup and it could compete against the Ram Ecodiesel. Obviously this motor would be the fuel Economy motor for these trucks and I'm willing to bet whoever had the most fuel efficient truck on the market will sell quite a few of them.

I doubt it, but would be interesting to see it. The diesel Colorado/Canyon is already pretty close to the half ton trucks, and if I'm looking for a diesel full-size, I'm going to the full 6.6 Duramax/Allison.

I do think Jeep is missing a big opportunity with a diesel Wrangler.

Wasn't the diesel wrangler just confirmed last week? For the next gen that is, like 2018.

I hadn't heard that, I hope it's true. Probably be a $50k Jeep though!

I think it might be a bit small for the Silverado/Sierra. I would like to see that 4.5L diesel v8 that got shelved enter production, it might work well in the lower range trucks and Suv's.

short answer, no. They might do a small displacement v8 though

Okay so after actually reading its not confirmed …. but I hope their source is right. It makes so much sense why wouldn't they?

I don't think it would be too small. that 4.5L might only be good for a 2mpg improvement over the V8 and that hardly seems like a smart buying decision.

No. They had a wonderful, reliable straight 6 several years ago, that could have replaced the anemic 4.3 and the 4.8, but they didn't. They aren't going to put an OHC engine in their fullsize trucks until they fail or the government forces them to.

A small displacement V8 diesel doesn't seem worth it. It be good for what 25mpg if you are lucky. They could make a 30+mpg full size but for some reason they won't.

The small 2.8 has more power and torque that the previous 4.3 and that was sufficient to move the truck around.

Alex from Toronto > Luc - The Acadian Oppo

I probably should have clarified by saying it's to small. Well I thought since the full size trucks weigh more the the Colorado/ Canyon it would put more stress on the engine because of it.

I'm starting to think that might be the case.

If I was a manufacturer I would have as many options as possible to attract as many buyers as I can. It's not like they are developing new power plants it's all stuff they already have in their part bins.

I don't understand Why they wouldn't make this stuff as a made to order thing only if they are worried it would sell all that well.

you need what 5 trucks to go thru the crash testing process so that would be what a 100-150K investment for GM to get this certified.

Nope because of the new 4.3

Kinja'd!!!

285 hp, 305 lb-ft of torque, towing rating of 7,200 pounds and 24 mpg.

is not about what will work is about strategy. They already have a mileage champ truck in the D max 2.8 Colorado, the dmax half ton will be about max towing and decent economy

The Ram has a 3.0L and the GM has a 2.8L. I don't think the 0.2L would make all that much difference. I'm sure it would be plenty capable.

Jordan and the Slowrunner, Boomer Intensifies > Luc - The Acadian Oppo
03/18/2015 at 22:00

It's not quite as simple as that, it isn't just the price of the trucks that cost so much with crash testing. But I can't help but to imagine how perfect the Atlas would be now with direct injection...

22mpg in 4x4 trim, with the mini d-max that could be closer to 30mpg.

If the 4x4 got 24mpg then I would say that's pretty good, but in reality the 4.3 is only good for 1 extra mpg over the V8 and that's pretty damn disappointing

Oh true I forgot about that v6. Derp moment.

You're forgetting GM, or any other maker, doesn't care about what you want. They care what their investors/shareholders want, which is to make money hand over fist. So they meet Gov't standards and trending designs then hawk the stuff to us. Order a crate engine and throw it in the truck if you want it bad enough.

Wait a minute was the Atlas 4.2L 6cyl ever made or used in anything? I've never heard of it until just now.

Jordan and the Slowrunner, Boomer Intensifies > Luc - The Acadian Oppo

Trailblazer, Envoy, Ascender, 9-7x, Rainier, and Bravada.

Luc - The Acadian Oppo > Jordan and the Slowrunner, Boomer Intensifies

So it was essentially only ever used in one vehicle. Aren't all those the same vehicle underneath?

So yeah I guess it would of been far superior to the 4.3 of the time. 291hp is a lot better than the 195hp in the 4.3. Heck it was probably more powerful than the 4.8 at the time too.

Except for the fact that it wouldn't get 30mpg with 4x4. The size, weight, gearing and aerodynamics make that number impossible to achieve. Also never base fuel economy numbers on the mythical European numbers as those are purely bullshit.

If the Ram Ecodiesel can achieve 27mpg in 4x4 crew cab fully loaded version I see no reason a red cab short box 4x4 couldn't get dam close to 30mpg.

Jordan and the Slowrunner, Boomer Intensifies > Luc - The Acadian Oppo
03/18/2015 at 22:31

Yep, pretty stupid. We had one, and that was literally the only redeeming factor, and that engine was perfect. It would haul ass, it would pull well, and my dad could get 24 mpg out of it(it was even 4WD). Plus, it's all alloy, so it weighs around the same as an LS.

The more you know I had never even heard of it until 30 mins ago.

They can also be turbo'd :)

I think they sound pretty mean.

They love to rev as well.

The Trailblazer SS was originally supposed to have a twin turbo one of these. It's a shame that it never happened.

If it was the entry level engine and didn't cost $3000 + to order then sure I would. I dont have a problem with the small displacement as long as the torque is adequate.
