Following the announcement of the 2024 Chevy Silverado High Country in Brazil in late June, General Motors has just revealed the powertrain that Chevrolet‘s full-size pickup will have in the country and South America’s largest auto market.
GM’s Brazilian subsidiary has confirmed that the 2024 Chevy Silverado is its next launch in the local market and revealed that the Bow Tie brand’s iconic truck will be offered in an exclusive configuration for Brazil, comprised of the top-of-the-line High Country trim level with the standard 5.3L L84 V8 naturally aspirated engine. Until now, it was believed that the Silverado would arrive with the 6.2L L87 V8 engine.

“In addition to a unique combination of equipment, Silverado will reach the national market with a state-of-the-art 5.3L V8 engine, capable of optimizing the activation of the number of cylinders according to the running condition, to improve efficiency and performance,” said Executive Director of Marketing at GM South America, Chris Rego, in a statement.
In particular, the 5.3L EcoTec3 V8 gasoline engine confirmed for the 2024 Chevy Silverado in Brazil has an output of 355 horsepower and 383 pound-feet of torque in its North American configuration, since the company has not yet announced the homologated figures for the country (which could increase slightly when using ethanol). Although there are no details on the rest of the powertrain either, it is highly likely that the engine will be matched with the GM 10-speed automatic transmission.
With this unique powertrain configuration, the 2024 Chevy Silverado will be the least powerful full-size pickup in Brazil, but it comes with the promise of being the most fuel-efficient. In this sense, the exclusive Dynamic Fuel Management technology of the Silverado’s V8 automatically adjusts the number of active cylinders according to the instantaneous need, optimizing the performance of the engine to improve efficiency and fuel economy.
The 2024 Chevy Silverado High Country will be shown to the Brazilian public for the first time later this month during the Expointer 2023 agricultural fair, which takes place from August 26th to September 3rd at the Assis Brasil Exhibition Park in the Esteio municipality, in the Rio Grande do Sul state of Brazil. GM Brazil will continue to reveal more details of the 2024 Silverado in the coming weeks as the official launch date approaches.

Same engine HP/TQ output for 10 years!!!!!! SMFH..
I have deactivated my 2018 Denali 6.2L of AFM and get 1 MPG+ better fuel economy then with AFM garbage on. Runs so much smoother as well without it shifting back on forth from 4 cylinders to 8 cylinders.
I agree it’s best to deactivate the AFM. It’s unnatural and can’t be good for long term engine life.
This unit doesnt have afm, but DFM. Also, studys show the only was to get worse fuel economy with AFM is if you jackrabbit the throttle all the time, and ADM is switching on and off rapidly, causing continuous fuel retrim. Normal drivers see great economy improvements with afm. Once my father deleted afm his average dropped from 17 to 14.
Afm also actually reduced engine wear, AFM engine upon rebuild show smaller ringlands and less carbon on the rings. This is due to the engine running more efficiently at part load. AFM has a bad name because a bunch of people in the first generation didn’t change their oil and sludged the lifters. Current AFM and DFM engines have better lifter protection.
May i also add, the 5.3 makes its ratings on 87 octane. The 5.0 makes its power on 91, the hemi is rated with 89. When all 3 have 87 in them the get almost identical power and torque. The 5.0 on 87 makes a little more power, but less torque down low
Yes and no. GM needs to revise the “% oil life remaining” calculation to discourage folks from overly extended oil change intervals. GM also needs to specify full synthetic oil be used in all applications unless “% oil life remaining” calculation is altered.
This response is BULL****. I’ve had 3 silverados with the AFM , and ALL of them had lifters fail… it’s been a nightmare & GM knows it. Now, all the lifters are the same, so expect lots of failures.. I gave up on the 5.3, and run the duramax LZO, 25 mpg all day long… the 5.3 is dead..
No you didn’t. I laugh when I see these posts on the forums. Fuelly and independent tests say otherwise. AFM is like 4-8% average savings and start stop is like 5-10% (conditions may vary obviously and this is going off memory). You are in the minority if that is the case and can be attributed to a placebo effect. You drive better to beat that V4 number just so you can get that preapproved number in your head.
The AFM is basically for the EPA because on paper it works, in practical application it doesn’t.
Fully .com says otherwise. Economy tanked for the 2020 MY with the “build shy” strategy that saw AFM deleted from the factory. That real use data as well.
Oh how incorrect that is. They wouldn’t spend all that money on this system just to earn a few epa credits. It works, can see it just in watching the mpg meter when it changes back and forth. Those few that say it doesn’t or they saw an increase are a placebo effect., They just want to so bad hate it and not see it work they drive in a different manner so they see their results they wanted to see because they hate V4 oh so much., Well guess what, it is what is keeping the V8 around even further…
So a study was done to see why people saw increased MPG when disabling AFM, and it was discovered those who drive really aggressively are constantly shifting between modes, and with each shift the fuel trim, spark advance and injector timing has to readjust, causing a momentary drop in efficiency. Normal drivers see a 15-20% increase when in V4 mode, agressive drivers might see a 5% decrease. Doesnt matter though as AFM is out and DFM works differently. Ive also heard that DFM has the computer monitor the deactivation to sense when lifters are going bad and can advance deactivation on failing lifters and just choose a different firing sequence when one has failed entirely.
Add this to that the 6 speed transmissions and up also monitor shift quality to save clutches, the current powertrains are very bulletproof.
“The least powerful but most fuel efficient” does not sell trucks GM! Don’t try this in North America. You will lose even more customers to the competition! GM needs new leadership now before it’s too late.
This is Brazil and no it is not being offered here. Even if it was you would have to order it as you get more options.
This is the right thing to do as prices and economy in Brazil is much worse there and they need all the help they can get.
Leadership is doing well. Look at how GM is doing compared to the competitors. Truck people want mpg as well, why is the forum littered with questions asking if this or that or these tires or this lift will impact the mpg. It helps sales, plus they are one of the last hold outs of the oh so image important V8…
I am not buying a full-sized truck for fuel efficiency. I am buying it to pull and haul things, don’t neuter them!
Agree, but with the 3.0 there is no sacrifice of power, which was the point, it rivals the 6.2 for torque. I am a huge fan and hope to have that engine in my next Silverado.
Is the 6.2 still optional?
To me, the current 5.3 with 10 speed is the perfect powerplant. My previous 2020 High Country had it and i absolutely loved it. I don’t tow, but i do haul – mulch, topsoil, pallets of pavers, trees, lumber, etc. I agree it’s not extreme use. But I also drive my trucks a lot for city driving and long hauls too.
My current 2023 has the 6.2 of course with the 10 speed. I love it. it’s quick and sounds wonderful. But it is a bit more thirsty and takes 91 octane. I dig the 6.2 of course and am not complaining. But the way the 5.3 goes on about its business dutifully exceeds all expectations. My next HC will have the 5.3. Buttery smooth, quiet, yet jumps into action when needed.
FYI, the 6.2 doesnt require 91. Its recommended, and the owners manual says if any pinging is detected move to 89 or 91 immediately. If Inwere you id run 89 most commonly for daily use and only 91 for towing/fully loaded. If your on a road trip alterating between 87 and 89 should be fine for highway cruising.
Of course But if you’re running them hard – its best to keep the average octane in the tank around 91. I use VPower which is 93 for alternating tanks and Shell mid-grade (89) the other fills.
But on the sweet lil’ 5.3, all it needs is 87 to do its work – this was my point.
Enjoy!
Yes and that’s because the 5.3 has 11:1 compression ratio while the 6.2 has 11.5:1..
Oh no $hit?! Who knew??
Come on dude. Of course it’s because of higher compression.
What’s your point?
The knock sensor should retard timing instantly to avoid detonation albeit at a sacrifice in mpg and power.
I have a2024
GM needs to wake up and ace that stupid 5.3 – the hemi and eco-boost are way better and more fun to drive and more power GM is losing. Slowest truck in the segment. I always buy GM trucks but if they didn’t offer the 3.0 diesel or 6.2. I would not buy anymore.
Its called the 10 speed. The calibration of the 10 is way snappier.
Also on the newer versions even with the 8 speed there is a “sport mode” that increases responsiveness. The tuning is really relaxed with the 5.3 to give it good economy and that caddie feel.
You need to read the complete terlet mags you are studying for your “facts”. GM is not losing anything.
Winning.
