3.0 Liter Inline Six Turbodiesel

GM has announced that the 2019 Silverado will have some new engine options, one being a 2.7 Liter turbocharged/intercooled inline four, and another option being a 3 Liter inline six turbodiesel. From what I'm seeing online, this 3 liter straight six turbodiesel is being referred to as the Baby Duramax. Further, I'm reading that the Tahoe and Yukon are based off of GM's Silverado line of pickup trucks, and options implemented there may find their way into Yukons/Tahoes/Suburbans.

What I'm curious about is if anyone else would be interested in having a Yukon/Tahoe with that straight six turbodiesel.

Myself, I was hoping an engine like this would make it into something like the Trailblazer that they currently sell overseas and that GM would start selling that here in the US, but from what I understand, GM doesn't want to cut into their crossover SUV sales with something like that. Since GM doesn't want to sell me the current traiblazer here in North America, the next best thing I can hope for is a Yukon/Tahoe with the baby duramax.

In my head, it'd offer reasonable full economy for a daily driver and for the occasional long road trip. Body on frame construction is what I'm looking for because of towing capability and the occasional trip into the boonies (western US in the Rockies), the missus has nixed getting a pickup truck since we need to haul kids and cargo around on a more frequent basis than I need to haul things in a bed, and need the occasional extra seating for when we take guests+kids or grandparents+kids somewhere. In my own opinion, the 3 row SUV with a utility trailer offers greater flexibility than a pickup for my own use at this point in time. The utility trailer has a wider usable bed (no wheel wells) and has a rear gate that also functions as a loading ramp. Roll or carry your cargo straight into the bed, you're good to go. The aussie version of the current traiblazer offers a snorkel option, which I thought was a cool option, but when I mentioned it to the missus she just laughed at me. When the zombie apocalypse happens, we'll see who's sorry when we can't ford that stream that isn't over six feet in depth at all points.

I've been trawling the news sites to see if the baby duramax will make it into this vehicle line but so far, no news.....

Too small. The 6.6 Duramax is perfect for either chassis, 1500 or 2500. A 2500 Suburban with the L96 can do it all too while using more fuel and saving the expense of a diesel conversion.

It would have to depend on what the specs are. I am sure that the same engine choices will be available. The thing is though, the gap between diesel and gas is not so great anymore to justify both the extra 5k cost (my guess) and the extra cost of the fuel. Here in SoOntario, Diesel does not go up or down as much as gas but usually stays around 5 cents to 10 cents a liter more. The other reason I would not go for it is, outside of the warranty period you still have a specialized engine that not many mechanics are going to be familiar with and you could be held hostage. Other than the diesel, I am sure that pickup purists are puzzling over having 4 cylinder in a full size pickup and the tuners are probably already at work trying to figure out how to defeat the multicylinder shut off now up to seven at once or a combo of them. The other item will be defeating the auto stop start feature because I don't think there will be a button to shut it off, my 2018 Terrain does not have a way to turn off that feature. The Diesel will also have that autostart feature.

I have the 3L Fiat Ecodiesel in my Jeep Grand Cherokee and I love it. Good enough power even towing through the mountains of Colorado and great fuel economy. I average 17.5 mpg (hand calc) towing a travel trailer. I don't care about it for saving money per se but getting just under 400 miles per tank while towing is awesome.

I would love it if the next gen Tahoes and Yukons were offered with the new baby Duramax. These vehicles weigh maybe 10% more than my Jeep so I don't think it would be a dog. It'd be interesting to see the power and fuel economy balance. Ford's new 3L Powerstroke for the F150 failed to do meaningfully better than the Fiat. Hopefully GM can do a better job, but even if it's about the same I'd still consider it.

Saw a new diesel half-ton Ram pickup at the boat ramp the other day. Was pretty quiet, could barely tell it was a diesel.

They should just stick a modern LBZ Duramax motor in all the new trucks and call it a day. They run much better without all that emissions garbage.
