Their new diesel looks to be the most promising. Inline 6 the way God intended motors to be.

Now they need to pull a Cadillac, mount it transversely in a 6 speed manual suburban, with start stop and an electric rear axle.

Just read about this today; only issue I see with the four is with the kind of people that put glasspack mufflers on a truck just to make it loud... they likely won’t like it...

Personally I’d like to seem them have added the DFM system from the V8 to the base V6 and maybe added a roots blower...then the engine heirarchy could go, 5.3, 3.0DMax, 6.2, 4.3SC

General Motors offered a Two-Mode Hybrid system for its Chevrolet Silverado and GMC Sierra pickup trucks from 2009 through 2014, and the same system in its Cadillac Escalade, Chevy Tahoe, and GMC Yukon full-size SUVs.

Sales totaled roughly 30,000 units among all vehicles over several years, and GM no longer offers a hybrid system on any vehicle above a mid-size passenger sedan.
XL Hybrids will be retrofitting hybrid systems onto F-150s for a 25% MPG improvement and F-250s for a 50% increase. They estimate production in 2020. https://www.greencarreports.com/news...start-in-march

Workhorse plans on selling $52,500 plug-in hybrid trucks that will get 28/32 later this year. https://www.greencarreports.com/news...ublic-for-1000

Here is explained the different number of cylinders, and their benefits. For a turbo engine, 3 cylinders (or 3 cylinders per turbo) is preferred.
(Some of the diagrams show the wrong number of cylinders, ignore that.)

Apparently some Dodge owners already disable cylinder deactivation on the V8 because they don't like the sound of the 4-cylinder mode.

Those owners will DEFINITELY not like 4 as the default, switching down to 2 at times!

I regularly walk on a stretch of road where cars are in low load conditions (50 kph/30 mph, slightly downhill), and you can definitely hear when the passing Dodge/Ram trucks are in 4-cylinder mode. They must have a louder stock exhaust.

I haven't been able to hear when the GM's are in deactivation mode.

It might be a hit if GM made the 2-cyl mode sound like a Harley-Davidson.

Does that mean 3 cylinder sedans are in the future (besides the Mirage)?

If only the FE technology being applied to trucks and SUVS was being aggressively applied to cars....mid-size sedans would be getting Mirage numbers without trying.
It would take a lot to get there.

The Civic 1.5T can get near Mirage numbers on the highway with conscientious hypermiling, but in traffic, weight is weight. With trucks, the baseline cost is so much higher that you can throw a whole lot more money at the problem than in sedans.

Now if you could give me something as small and as light as a Mirage with the power of the Civic, however...

The 1/2T 6.2L could already get 25-mpg at 60-mph while solo. That’s with a tonneau cover from a report I trust.

More than that seems pointless. It’s a truck, and meant for work. Given that number is pretty well the same as my “pre-emissions” 2004 Cummins, means there’s sure not any reason to buy diesel.

Gasoline was always easier to live with. And I can’t see a reason for the I4 ( I agree about engine stress vs longevity).

An Aerolid is what’s needed.

Tows a 12k trailer AND can do outstanding while solo.

.But note how the sales pitch is to “personalities”. We live in a world of children. The adult models were discontinued

Honestly I’m surprised they used a 3.0L in-line six diesel when they already had the 2.8L Duramax that’s being used in the Colorado and the G series van... seems like they coulda bumped boost pressure a little and that woulda worked fine. We’ve already seen what that engine is rated in the Colorado...
