Chevrolet has announced that the 2024 Chevy Silverado 1500’s turbocharged 2.7L I4 L3B engine will be called TurboMax. The new name follows a GM trademark filing made earlier this year, per previous GM Authority coverage. The TurboMax gasoline engine will be one of four powerplant options offered by the 2024 Chevy Silverado 1500.
According to assistant chief engineer, 2.7L Turbo Engine, Kevin Luchansky, the Chevy Silverado’s TurboMax four-cylinder is “built like a diesel,” and is designed to “win over both diesel and V8 customers alike.”
Specs include maximum output figures of 310 horsepower at 5,600 rpm and 430 pound-feet of torque at 3,000 rpm. Notably, the TurboMax four-cylinder’s peak torque figure surpasses that of the Chevy Silverado’s naturally aspirated 5.3L V8 L84 gasoline engine, which is rated at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm. The TurboMax engine will also deliver an available 9,500-pound Max Tow rating.
Further engine options for the Chevy Silverado 1500 include the naturally aspirated 6.2L V8 L87 gasoline engine, which is rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm, as well as the 3.0L I6 LZ0 turbodiesel Duramax, rated at 305 horsepower at 3,750 rpm and 495 pound-feet of torque at 2,750 rpm.
The TurboMax engine is expected to be available for several 2024 Chevy Silverado trim levels. Currently, the turbocharged 2.7L I4 L3B is equipped as standard on WT, Custom, Custom Trail Boss, LT, RST, and LT Trail Boss trim levels, and is not available forZR2, LTZ, or High Country trim levels. The upcoming 2024 Chevy Silverado is expected to offer identical availability for the TurboMax engine. Looking ahead, the TurboMax name will also be applied to the four-cylinder under the hood of the Chevy Colorado pickup truck.
Per a GM Authority exclusive, the start of regular production (SORP) for the 2024 Chevy Silverado 1500 is set to begin July 17th of the 2023 calendar year at the GM Fort Wayne plant in Indiana, the GM Oshawa plant in Canada, and the GM Silao plant in Mexico. Dealer orders begin this coming June.

Ill take an all new 5.7L 350 please GM!!
TNTGMC??
I’m a sucker for nostalgia and think a 350 V8 would be great for the 6th gen small block. They also need a 6 cylinder turbo of their turbo 4. 1 V8, 2 turbo gas. If they only have one V8 they won’t handicap it like they do with the 5.3 since they have the 6.2 too.
Ya, I could go for a ‘350’, that could happen. The I-6 turbo based on the ‘turbomax’ has been terminated however.
I read that article and it’s very unfortunate. It was a very poor decision by GM. People will not accept this 4 cylinder like they have the v6 Ecoboost or an i6 Turbomax. It would help if they actually had good MPG, but they don’t.
Yes, 350 please!
I don’t think renaming the engine will help. Might help a bit if they paired it with the 10-speed transmission and just discontinued the 8-speed. Even if the 8-speed has been fixed, not many people have confidence in it. The GM in the half-tons just doesn’t compete well vs. Ford’s 2.7 V-6, which has more horsepower, and is EPA rated at 4 MPG better on the highway and is paired with their 10-speed. If I were getting a half-ton, I would just skip over the 2.7 and get either the 3.0 Duramax, or the 6.2. Kevin Luchansky has been doing a good job of promoting the engine, but unfortunately, I don’t think it will help sales much.
Outside a 2wd regular cab delivery truck the GM 2.7 is a bust. Perhaps those lightweight numbers would allow it to stay out of boost and see a larger mpg gain. It’s just not the right engine for a 4wd crew cab.
The Ford 2.7 is a spunky engine that gets great mileage. It’s not the rocket the 3.5 or 5.0 is on the highway but it rips to 60 and gets good mileage.
What are the higher maintenance costs exactly? It has 1/2 the plugs of the V8, both engines have coolant and belts and oil, is there a magic 4 cylinder turbo fluid that needs to be serviced every 10,000 miles that I don’t know about?
There aren’t any higher maintenance costs, just some clueless old school guys that don’t know what they are talking about. Subpar reliability, really? This motor was one of the strongest ever in their durability and reliability torture testing from engineers. It is way over built in a diesel like manner. It is a great engine and show cases future ICE technology to try and stave off the EV revolution a little longer.
I don’t know of any aluminum diesel truck engines, they are iron or CGI. Like the Ecoboost 2.7 and 3.0. What about the GM engine is “built like a diesel”? sounds like marketing BS to me.
I would actually order engineless truck and have race shop build me at nitro methane 700cid blown V8 with twin superchargers and nitrous so I can drive it to the office in 15mph traffic……by myself…..with an empty bed…..
the people who avoid are the ones who know nothing about trucks. It out performs the 5.3 in most truck related metrics. You do know for towing and hauling you want a ton of down low torque right? Guess which one has that in spades? It is a much better engine to drive in day to day and towing and hauling.
Reliability? Shesh, have you done any homework on this engine? It stomped all over their durability torture tests per the engineers that designed it, it was way over built.
About time GM starts naming their engines again, instead of just production codes. I just don’t get the hate this upgraded and strengthened 2.7L turbo engine gets, it’s a capable power plant and 310hp with 430lb/ft torque isnt anything to scoff at. I’m not really a truck guy but if I would want a truck I’d get a 2.7L turbo Custom 4×4 Silverado, it doesn’t even have to be a Trail Boss just something to get the job done moving things. However I am a realist, GM should prioritize the 2.7L turbo for Colorado production because of misplaced consumer resistance of Silverado truck buyers. GM should consider adding two more cylinders to the existing architecture for a tree stump pulling turbo straight 6 truck gas engine.
The 2.7 4 cylinder might have been a potential hit in whatever truck they put it in IF it had 4 cylinder gas mileage. At the same mileage as the 5.3, NOBODY would risk buying it over a tried and true V8. (Other than someone who doesn’t know trucks and just has to have one).
“I can’t wait to drive my 4 cylinder full size truck” says know one ever.
Please stop calling things ‘Max’, other than Duramax.
VortecMax didn’t sound good, either.
This engine is perfectly fine for 99% of pick up drivers that use it as a car and drive around with a bed full of air most of the time, there are plenty of real world reports of 2WD 4 door versions getting over 30mpg on the highway, which is really good for a full size truck.
I think Turd Hole Max is more fitting
The turbomax is a good little engine for it’s intended purpose IMO. There is a large number of people that drive trucks because they like the size and ride height, but don’t really use it like a hard working truck. The little engine makes great torque and is a bit lighter than a v8, so for around town driving (especially with a gentle foot) it should do a bit better on fuel than the 5.3L. (not highway driving)
Companies that do parts delivery and hot shots, as opposed to dragging heavy trailers it would also be pretty good.
Those of us that work our trucks want the V8. The 5.3 (and even 6.2) cruising on the highway or towing a big trailer would actually get better mileage and last longer.
This engine has the same issues as the ecoboost. Too little engine, too much boost. It affects mileage and reliability if you are working it hard.
(this is an outside perspective as I still run an old 3/4 ton diesel and likely will never go back to a 1/2 ton)
Good points, I couldn’t agree more!
The difference is the Ford EcoBoost gets good mileage, or at least better than this.
You keep harping on this so I looked it up….
2023 2WD Silverado crew cab 19/22
2023 2WD F150 crew cab 18/25
2023 4×4 Silverado crew cab 18/21
2023 4X4 F150 crew cab 16/22
The F150 is a regular Prius compared to the Silverado….the differences are just, wow, incredible….
The Silverado does have 30 more lb-ft of torque than the Ford at the same RPM too….
The first gen ecoboost really didn’t get good mileage, and based on my friends trucks, the new ones still aren’t better on fuel than the 5.0L…but less reliable.
Dealership tech here. We sell plenty of 2.7Ls at our location and it’s been fairly popular since launch 4 years ago. In our shop, I’ve yet to see a single major engine job on the turbo but routinely see newer, lower mileage V8 in for major work and replacements.
Thanks for weighing in. Just wondering if you have seen any AFM related problems at all with the 2.7? I haven’t heard about any, but I have heard about plenty of them with the bread/butter 5.3 and 6.2 (lifter issues), especially back in 21′ and the early versions around 2007-2009. Not sure what the mechanics of the AFM system are in the 2.7, maybe the hydraulic lash adjuster. I have a 5.3, but I installed the range AFM disabler as soon as the warranty was up to reduce my risk of lifter failure.
No AFM problems. The only common issue we’ve seen is the EVAP purge pump calling it quits after sucking in gas from a soaked charcoal canister. It’s a combination of a badly designed part combined with owners that “top-up” their gas many times after the first click. That being said, it’s an easy diag on a relatively cheap part that’s fast to change combined with an easy conversation with the customer.
Thanks for the feedback, sounds like a solid engine so far! Now if they would just offer it with the 10-speed, I think they could up their sales a bit. As for me, I’m trading in our 9 year old Suburban with the 5.3 (has been flawless), for a 24′ GMC HD Duramax, should be here in a month or so as it is already built.
Considering the V8 lifter problems, I see you point.
I think this engine is pretty good at it’s intended purpose. For the large number of people that don’t trailer or really work their trucks, this is a stout little engine for around town driving.
It has more torque than a 5.3 so it’s zippy in town, and a lot of truck buyers use them as daily commuters, not trucks.
In town with a gentle foot, the little engine should do a little better on fuel, (not on the highway, and not working hard.)
For those of us that use our trucks for doing truck things, towing and hauling heavy loads, they still offer the V8’s…or 3/4 tons.
Personally, I threw 2 more cylinders at it, added a 2 speed 4WD, and sprayed a little diesel sauce in it, and now I’m towing a 26 foot trailer behind it. Duramax has a better ring to it than Turbomax
The mere availability of this engine seems to trigger anger in the “micropenus” crowd….
Obvious attempt to high jack the Duramax name and fame.
Should premium fuel be used with this 2.7 Turbo
They need to figure out why the mileage ratings are so poor for this engine especially for 4X4 full size trucks and the new 4X4 Colorado which rates even worse than the full size trucks in the city figure. If Ford can get 18/24 from their 2.7 V6 and 4X4 and 18/23 from the larger 3.5 in 4X4 then why can’t GM’s 4 cylinder that shuts down 2 cylinders and has stop/start and every trick in the book geared towards MPG!
Except they aren’t-
2023 2WD Silverado crew cab 19/22
2023 2WD F150 crew cab 18/25
2023 4×4 Silverado crew cab 18/21
2023 4X4 F150 crew cab 16/22
Thats with 30 more lb-ft of torque than the Ford too…..
I’m hoping new Colorado owners experience actual fuel economies much higher than the EPA estimates – which are disappointing to say the least. Nevertheless, the truck is going to be fun to drive!
Since this part of the thread was deleted due to the other bozo, I still need to reply to this from “Alex”
“Turbos, intercoolers, wastegates, extra seals, AFM camshaft crap.
Your automotive Ignorance is noted”
No-your automotive ignorance is noted, none of those are “maintenance” items.
Those are extra failure points on an engine that already doesn’t get any significant fuel economy benefits. Which increases the maintenance cost.
So again your automotive ignorance is noted. But go ahead and buy a GM 2.7 Turbo then when it fails you’ll be laughed at.
I’m not sure you even understand what the term “maintenance” actually means at this point, but go on feeling superior about yourself if it makes you feel better.
I’m not in the market for a truck at the moment, but I would consider a 2.7 LT Silverado if I was in the market for one.
Maintenance and repairs are two different things. One is to minimize the other. Maintenance is basically identical on both engines. As I stated in another comment, I’ve seen countless T1 trucks with V8’s come in for major engine repairs or replacements but I have yet to see one single turbo come in for extensive repairs.
Just make an engine that will compete with the Trx an raptoR.
Mpy dealer has 18 1500s with the 2.7 setting on the lot today and none V8s. They tell me that they are having a hard time moving the 2.7s.
I’ve had the 2.7 L3B, now “TurboMax” for about 6 months… So far its a great engine. I have no regrets! And I don’t want to hear about how it won’t last 20 years! I don’t care! My cars are kept about 4 years, then it’s time for a new one. Chevrolet outdid itself with the Custom package. It’s a great value, and this crew cab is ridiculously comfortable.
I own a 22 Silverado Custom with the Turbomax and love it. Seeing more and more of them at job sites too. I’m a landscaper and other than hauling big loads of rock which I use the HD for it does everything else well. When loaded up it surprises me how smooth it is off the line under load and at normal speeds. I Haul with a 1500 lb dual axle trailer and loads are around 3000- 4000 lbs or less.
Great workhorse of a light truck and it has enough power for my needs and gets around 22 mpg highway. I’m in Florida so the terrain is mostly flat but I’m taking to the mountains later this year and will see how it does with that.
Besides the motor I love the spacious cabin and looks of the new style front end and all the included safety features.
Yes I was skeptical at first but after the test drive got it at a great price with extended warranty just in case.
Make a 5.0 super charged to make a fast truck
I’m pulling a 21 foot boat and a 22 foot trailer. I’ll stick to a 5.3l engine !
Let the customer buy the V8 he wants in his Silverado, not the 4 cylinder they try and force the customer to buy. Gm should at least give the customer the option to buy a V8 in a regular cab short bed Silverado. I have drove a Chevrolet Silverado for 30 years with a V8, I don’t want any 4cylinder or V6 in my Silverado Regular Cab Short bed Truck!
