Underrated username

Not buying any Government Motors shite. Should’ve been allowed to go bankrupt 17 years ago. But no - we got to prop up the boomer union members pension plans among other bullshite business decisions.

Next thing you know they are going to dust off this design.

And when it comes to turbo motors….long term an inline design with a single turbo just has fewer failure points.

Ram has an inline 6 turbo engine that sounds pretty cool

Still hecho'd in Mexico?

3 plants make the Silverado and Sierra. They are located in Michigan, Indiana, and Mexico.

I think they are expanding the Flint, MI plant to skirt tariffs.

The 90 year old Tonawanda, New York plant will be handling most of the gasoline engine production. Interesting thing about this is that they are handling the crankshaft with cracked caps of the new engines. Currently they do this for the 5.3L V8s but the crank and bearings of the 6.2L were are shipped in from Mexico. I suspect this move is because of quality problems from Mexico, but I wonder if the new 5.7L V8 engine they are building starting next year will have a cast iron crankshaft and not a forged steel crank.

The 2.7L Turbo will continue production in Indiana, so that's definitely going to remain an engine option for the new full sized GM trucks. Some folks think this could be paired with a hybrid electric motor.

Flint Engine Operations is still going to be producing the 3.0L 6 cylinder turbodiesel well into 2030 (union contracts tell that story), so that's going to be an engine option on at least some of the new full sized trucks too. This one is a favorite of mine. Hopefully the next generation Suburban and Yukon keep this motor as an option.

Supposedly the 6.6L gas V8 and 6.6L turbodiesel will remain for the HDs, but a 6.6L next gen V8 will be used for the Corvette eventually. So they will have a pair of 6.6L V8 engines that are actually not related to each other in design - one for performance cars, one for heavier trucks.

Hard to figure out their transmission plans because so many different plants crank them out. But I'm guessing the trucks will get the next gen 10 speed, with the already new 8 speed carrying over from 2023+ model year base/entry level trucks.

All they change is the grill and taillights.

All trucks look the same.

Except the Cybertruck which is very ugly. .

It would definitely help the reliability

True, but the updated oil pump in the L84 has resolved a lot of the lifter issues people have complained about.

The sightly older L83 (and even the current 6.2L L87 motor) use a variable displacement pump. I'm convinced the issues with lifters is actually caused by oil starvation, and not a defect with the actual lifter itself. The lifter fails from inadequate oiling, and that seems to have been mostly resolved in the newer models with the static rate oil pumps (that also probably cause a little more fuel consumption).

but I’ve always found the 5.3 lacking in off idle/low rpm power.

They used to rip....then GM started putting in 3.08 and 3.23 Axle Ratios to save fuel. The trucks have also gotten much bigger/heavier as well. They seem to still have plenty of power if you can get one with 3.73 gears, but they are hard to find - they might not even make those anymore.

Bumping it to 5.7 or 6.6 would definitely help.
The 5.3 makes great power at an rpm range I rarely drive at.

I hope they keep the torque curve and that responsiveness. Just ramp up the output by about 15-20%.

I remember it was controversial when it came out, because the old 350 and 305ci V8s from the 1990s offered most of their torque at a lower, more accessible RPM.....but they also felt wheezy AF on the highway. People love those motors because they were powerful for their day. They became boat anchors the second the LM7 came out.

I'm honestly a huge fan of the L84 5.3L V8 in current full sized GM trucks. That's probably my favorite half ton engine right now. And I love that we could get one in the 2027+ trucks too and they aren't moving exclusively to small displacement turbos. I'm a fan of the responsiveness and the sound of those trucks. And the highest risk issue with them seems to be lifters.....which is cheap and fairly easy compared to replacing turbos (which requires a cab-off operation on the Tundra and some ecoboost Fords).

I also love the Ram's HEMI and the earlier Ford Coyotes (before they used the wet oil pump belt). But if I absolutely had to get a turbo motor, it would probably be the Ford 3.5 and Chevrolet/GMC 2.7. I would run away from the Toyota Tundra with the twin turbo 3.4L V6. Don't know much about the Ram Hurricane, but it looks pretty good.
