These must be the last diesels of nox/terrain. Who knows they may become classics..as i suspect there are only a few thousands on the road.
May be GM should send us a "Limited edition" tag along with embroided headrest etc...

Happy driving !

Actually .. we recently bought a 2019 Acadia SLT-1 with the 3.6L V6. We are getting an average of 22 MPG around town mixed driving and averaged 27.6 MPG [ 65 to 70 MPG] on a several 150 mile round trips to a nearby city and some in city driving once there.

On a 330 mile interstate run we netted 28.7 MPG and saw a 50 mile DIC average as high a 33.4 MPG.


The 2.5L has a 3.87 final drive ratio and the 3.6L engine gets a 3.16 [contrary to some incorrect published GM specs]. So the 2.5L is working harder and turns more RPMs at a given speed.

Also, the 3.6L has AFM which I see going into 4 cylinder mode quite often on level pavement and steady speeds when highway driving.

We picked up a 2019 GMC ACadia SLT-1 with V6 [MSRP $40,785] for $30,902 plus a small amount of GM card cash that netted over $10,000 off sticker price [$30,779].

It has leather, 6 passenger seating and more than we had in our 2015 Equinox LTZ. Plus, the initial MPG is also better than the 2015 Equinox.


The new downsized Acadia is a completely different vehicle than your old Acadia and not much larger than our 2015 Equinox. . . which is what we found very likeable.

It seems the Diesel Revolution is over, Nissan Today just announced that they are discontinuing the Cummins Diesel in their Titan pickup citing very poor sales.

One of our other vehicles is a 2017 Chevy Colorado mid sized pickup truck.
After reading on other forums about maintenance, use of DEF fluid, fuel and particulate filter issues, and other problems . . . to me diesel has too much potential for issues and and also requires too much to be mindful of.

And one can thank the emissions stuff that has inflated the cost of buying a diesel. A diesel is complex enough with fuel issues over and above what gasoline has. The motor has to be built with better components. To make the engine eat its own feces, having to water cool that before it goes into the intake, and the soot loading it does to an engine really makes a modern diesel not worth the trouble to many folks. And I haven't even mentioned SCR/DEF and DPF issues. Having diesel fuel gel or ice up in cold weather and being sidelined on a highway in the middle of the night at -10F is not fun for anyone, especially those who are not diesel savvy and know one should always carry proper tools, fuel filters, diesel fuel additives, etc.

I deal with all these things for my commercial stuff. I can change a fuel filter along side the road in just a few minutes and be ready to roll again. I deal with it every winter. It is harder to do that on diesel cars and pickups usually than it is on heavy commercial trucks. And even though I have many decades of experience with diesels and purchase about 21,000 gallons of diesel fuel a year for my business stuff, I have no desire for diesel in my personal pickup and car. In days gone by, maybe. With today's diesels, no way. It takes a very special need to get me to even consider diesel nowadays.

And if we back up several years ago when diesel was fondling with $5 a gallon, one could barely give a diesel powered vehicle away. And it could always happen again. Many folks remember that and don't want the risk.

It is sad that the OEM's didn't offer up competent diesels in smaller vehicles back in the 90's when it was more viable and the public could have become more diesel savvy early on. They drug their feet too long and wasted a lot of R&D. They are doing it again with not investing in better performing engines that take up half the space of a typical V or inline engine, use 50% fewer parts, has a lower stance in an engine compartment, and deliver better fuel economy.

GM had a developer doing just that right under their nose in Detroit. That developer ended up selling the tech to Chinese concerns. Check out the OPOC (opposed piston opposed cylinder) engine. It was modular and the engine size could be doubled by just adding another module. No extra tech involved. Was designed in such a way that it could use diesel, gasoline, propane, NG, ethanol with very little modification. Used electric driven supercharging. No valves, cams, or overhead crap on traditional engines. And the modules could be disengaged from each other during low power times and reengaged as needed without creating drag on the rest of the motor. A 8 piston engine would take up no more space longitudinally than a 4 cylinder inline engine.

Freedom is not the ability to do what you want, but the ability to do what you ought.

GM in Europe is a pale shell of what it once was there. In Europe its a different market, better climate and because of the obnoxious tax policies of their governments, Diesels are taxed lower than the gasoline models. They use the liter displacement charge, in other words the bigger the motor the bigger the tax bill. That and the fact that their fuel is taxed to dixie with charges not related to the actual price of fuel. Diesel again is or was cheaper over there and that is one of the main reasons that diesel fuel in north America was more expensive, the Europeans got to it first driving up the demand, that and the requirement for lower sulfur content.

I truly believe that the 1.6 in the nox and terrain, and cruze is a good motor and will stand the test of time. I myself like Copperhead would never entertain one in a personal vehicle because I work with them all Day long, so I see their problems and of course their strengths. Most Americans have to take Diesels on faith, and despite the near mytical status of the Cummins Ram engine which has as many problems as the other two companies will need to bear up when the time comes for out of warranty work.

If it aint a CAT its a Dawg.
