There are more than a few 2019 Silverado engineering feats, but one of the biggest is the addition of Dynamic Fuel Management. The new technology, which GM developed alongside a Silicon Valley startup, can shut down up to seven cylinders in the 2019 Chevrolet Silverado’s V8 engine and vastly improve fuel economy.
Roadshow sat down with the 2019 Silverado‘s chief engineer, Tim Herrick, who dove into more details about the technology. Foremost, Herrick said he doesn’t expect drivers to roll around with just one cylinder operating, but the fact the technology can do it if necessary is quite a talking point.
Right now, cylinder deactivation means either the Silverado runs on eight or four cylinders. With Dynamic Fuel Management, the technology will more carefully select which cylinders can shut down to maximize efficiency. Of course, when all eight cylinders are called upon, they’re ready for duty.
Herrick also described the technology as seamless and said customers won’t hear or feel Dynamic Fuel Management at work.
The technology will debut in the Silverado’s 5.3-liter and 6.2-liter V8 engines when the truck goes on sale later this year. Check out the full interview below.

Dodge has had that technology in the Ram for years.
Please…. everyone has a variation of the current MDS. What Chevy is introducing here takes it multiple steps further and is far more advanced.
Lol. On what engine and model? Have some evidence?
Mark, the Ram truck on the Hemi 5.7 liter only uses the same cylinder deactivation, as GM only allowing to deactivate 4 cylinders and going back to 8 cylinder. It works basically the same way as GM’s cylinder deactivation works.
This technology is here so we can hold on to the v8 options for years to come. For the people who don’t want to use it, either get use to it or dream of a world of no v8 enigines in cars or trucks.
And for the people who say the public is not asking for this technology, yes they Are! They are asking GM in the form of saying that we want a v8 to remain a option.
So I think we should embrace this technology because if we don’t these engines we want will disappear.
I want to thank GM for investing in technology that allows GM to continue having high horsepower v8 engines!
Seamless…right…just like AFM which they said was seamless, yet isn’t.
If you notice then yours has issues, I have never been in or owned one that I notice going back and forth with out looking at the V4 symbol. It is seamless, even notified by all the reviewers. If this is on par with the current system in terms of smoothness it will be great.
I have had several of these as an employee vehicle and could always tell immediately by the seat of my pants when it went from V8 to V4 and back. Maybe it has something to do with growing up driving a vehicle with a manual transmission and having that direct feel and interaction with it that apparently so few now have.
I owned an ’09 Silverado w/ 5.3L and AFM since new until last year and had no issues with it at all. It was smooth and unnoticeable. I knew it was in V4 mode only when I looked at the display.
This is what most experience while driving a truck with AFM. People that complain about the system will look for anything to validate their dislike of the system.
I don’t know why these types of systems really bother people. This with the addition of start/stop that people complain about. Which I don’t understand either, why does it bother people knowing the engine changes from v8 mode to v4 mode or if the car shuts off while stopped?
I’m willing to bet drivers like myself who tend to notice very small changes in what the vehicle is doing or in noise, sound or vibration will be able to tell. Still hard to forget the V8-6-4!
eddie, I was about to remind or inform Mark of the V8-6-4 myself but I guess being here at the river I have increased latency. Cheers!
I wish the would offer some sort of button to turn off system button like the auto start/stop. I’m sure the aftermarket will come thru with the tuners to disable. Ram you can disable by using manual mode on tranny, GM the same way?
