Chevy 1500 5.3L V8 vs 2.7L TurboMax I-4 | ULTIMATE Engine TOWING Comparison

[@79champions]

I just towed my 7000lb camper through the Appalachian mtns last week. 3.0 duramax. It just ripped up those hills. So impressed. Also ripped through def. That sucked.

@@79champions nice! I want a new GMC Sierra AT4 with the 3 L Duramax diesel. But I’m not willing to give up my 2018 Toyota Tundra or pay those high prices.

[@daveharris39]

My take on it is this: Honestly, ask yourself how often and how heavy you tow. If I had an 8000 lb (or heavier) enclosed trailer that I towed regularly, I would buy a 2500. If I towed a 3000 to 5000 lb trailer every day I'd go with a 1500 with a V8. If I only tow a small or light trailer occasionally, the 2.7T is fine. When it comes to towing, it's not so much about fuel mileage as it is safety; it's safer to have more truck than not enough truck.

[@Derham43]

I whole heartily agree with you, and my Chevy has the 2.7 turbomax.

[@TheGettyAdventures]

100% agree, I use this trailer to load down these 1500's and see how these engines handle a heavy load. If I was towing this regularly a 2500 would be my choice.

[@qwikz28]

So the question I would have then is what if you were towing a heavy trailer occasionally? I tow a 6000-6500 pound car trailer a few times a year and it's a bit sketchy with my Jeep Grand Cherokee L.

I've owned a few new 5.3 trucks (2001 - 285 horse /325 torque. 2006 - 295/335, 2016 - 355/383). Bought new 2023 Silverado Custom Crew 4X4 2.7 (310/430) 9 months ago. 8,000 satisfied miles later, finally towed our 2009 Rockwood travel trailer (33' & 6k lbs dry) for annual camp trip. 90 mile journey on mostly 2 lanes - flat - 55 mph limit roads. Never over 4,000 rpm's. Accelerated normally, shifted @ 3,000 rpm's, settled @ 60 mph @ 2,000 rpm's. 9.6 mpg w/ 87 octane gasoline. Guessing 1,000 lbs of food/water/beer/gear in camper & 500 lbs of firewood in truck bed. Perfect drivetrain for me. Tow a few times a year locally, similar payload/tow rating as V8, about 3 better mpg overall, $6k less. No regret choice for me, perhaps not for you.

the 2.7L is not a bad little engine but for towing a heavy load its probably not the best choice lol

Ah yes the longevity of GM V8’s and their lifters. 😂 At least they give the Turbomax a 100k mile warranty- while the V8’s only get 60k…. Lifters and cams are expensive to fix and they don’t want to be on the hook.

[@stevebeard7667]

Agree the 4 will be much more stressed over time than the 8 If it's worked hard.

[@michaeljones7735]

Thanks for a great informative video. On one hand, to wring performance almost the same as the 5.3 with essentially half the engine is pretty impressive. Different engines for different owners. My trailers top out at 5,000-6,000 lbs max, so the 2.7 works for me, if not for anyone else. It replaces a 3.0 liter diesel and has slightly more power and slightly more fuel consumption. Having dragged my heaviest trailer all over the US with that diesel, I knew the 2.7 would work for me, and it has.

[@JDC129]

2.7l was never meant to be the engine choice for towing. At least not consistently or on long distances. The 2.7l was designed for a light duty work truck or daily driver to HD(90%) of truck owners these days. GM does a great job of engine choices to match your need. I am honestly surprised they haven’t deleted the 5.3l with the 6.2 and 3.0 Duramax available for max payload and towing.

I have been saying for 10 years now, since they came out with the new 4.3L V6, that they should be using the same 3.921" piston in the base V8 making a 350ci 5.7L V8 to match the 5.7 Hemi and 5.0L Coyote more closely, especially since they came out with the 6.6L in HD trucks now, they could have made a 5.7L base V8 and put the L8T crank in the 6.2L aluminum block to offer a 6.6L option in 1/2 tons. They could have even sold a 5.7L in 3/4-1T Express vans and W/T pickups. Huge missed opportunity.

[@DH-hp7nv]

Good video Alex. So i have a company vehicle that is a 2019 with the 5.3. It uses the active fuel management system, not the newer dynamic fuel management, but it still sucks. Could you imagine, If GM would get rid of all the fuel management systems and just give us a v8, both 5.3 and 6.2 would be good buys.

[@ericj810]

I've pulled 8500lbs on a run in a 2.7 chevy. It did just fine. Held 60 up the mountains at 3800rpms with the enclosed trailer with that weight. Its a good engine. Travel trailer people love it over the 5.3 on the forums.

[@mikefromvernon]

That turbo 4 sounded like it was going to tear itself apart under load. They might be fine for smaller cars but when it comes to heavy loads like an 8000lb trailer I'll take the V8. That did not sound like it was going to explode from putting too much pressure in the engine.

[@ondago2]

Such a common pre bias confirmation. Pressure in an engine, which you call out is always when lugging and engine. Spinning faster and moving less cylinders might sound more generic and the friction is higher with more rpm but the"pressure" in the engine is likely lower because it has apparently dropped gears for easier loading on the engine. A new modern engine can survive years and years old occasionally screening up a hill. Even when they are 10 mile long grades, it's only a few minutes in the hundreds of life hours of the engine. It's not going to actually come apart from running 5000 rpm for he minutes. I really wish folks would stop perpetuating biased stereotypes about what are just machines. Whatever rpm it takes to make the needed tractive effort for the load, at that speed and gear is just what it takes. The engine brand new and for a decade or more, can take it just fine.

[@FredRTP96]

Biased much… ? The 4 cylinder is far more rugged being forged motor and sharing components and design as l5p

Try 11,000 ft above sea level. Seeing gasoline v6 turbos, I4 turbos overheating all the time here in Colorado Rocky Mountains while towing. V8s gas not typically NOT overheating while towing here in Colorado Rocky Mountains.

[@TheGettyAdventures]

it does seem like the V8's just handle workload better.

[@Chris-ut6eq]

Interesting, this is not something the YT truck channels talk about. I've not done much towing above 5k.

[@charlesb4267]

That is very interesting, I've not heard anyone mention this before and yet I have to wonder if it has to do with the fact that a boosted induction engine tends to retain a lot more of its sea level power over a naturally aspirated engine. Without a doubt an n/a gas engine has a fair reduction in power output at 11000 feet and less power output should equate to less generated heat ?. Conversely a forced induction engine will cram in the air into the cylinders to get good power but the air density flowing through the rad will be less and I believe equates to less cooling the higher the altitude, for a given ambient temperature of course. I was never towing anything when I did any driving while exploring Colorado and was quite happy NOT to have a boat anchor behind me to fail the engine or weak tranny of the truck I was driving.

[@icare7151]

@@charlesb4267 Heat kills turbos and engines. There is 10% less oxygen per volume per 1000’. Thus at high altitude there is less oxygen, less dense “air” turbos must work really hard to make up the difference and produce significant heat, engines are screaming in lower gears at high rpm. Limp mode due to overheating is common place even on Winter days towing with v6 turbos, I4 turbos vs the v8 they replaced.

[@charlesb4267]

@@icare7151 Definitely turbos spin faster to create the same boost pressure at higher altitudes, however I can't say I hear of turbo diesel engines having excessive issues at altitude although definitely every engine put on long grades and in summer time temps all are stressed and the person behind the wheel is the other factor !. One has to wonder how much ( or little ) testing has been done in Colorado with these newer turbo gas engines to design them to take that punishment. I am in Alberta and I know the passes over into BC is where some will have issues for sure but the coquihalla highway in the south interior of BC is where vehicles go to die if towing, it gets hot during the summer and there is a section of I think its over 8 percent grade so vehicle speed drops as does the air flow through the rad and so anything not up to the task is asking for a very bad day ... just like the longer passes in Colorado.

Hi Alex, Thanks for the video. This is the same drivetrain that I tow with. I have a 5000 lb travel trailer and it does a fine job with it. I was a little worried about the 3.23 rear gear, but the 10-speed transmission makes the magic happen. I did test drive the 2.7 8-speed but it just didn’t feel right. Everything was too busy. I think the 10-speed would be a nice option for the 2.7 to reduce the drama. Love my V8, loved the video!

From what I’ve understood the 8 speed is made to run hotter than the 10 speed for driveline efficiency. TFL noted the higher temperatures when they were towing with their Colorado. Much less weight but still the same temperature

[@michaeltutty1540]

When you are talking torque and horsepower, hard numbers are only part of the equation. Where the peaks land in the rev range is the other half of it. Oh, the 5.3 is putting out LESS torque than the factory 351W in my 89 Mercury Grand Marquis. It produced a reasonable 390 lb/ft at only 2,200 rpm. With a horsepower peak of 215 at 4,800 rpm, it was a very flexible engine. So much so that the performance axle ratio was a 2.73:1. The car was rated for a full 6,000 pounds of trailer with that ratio. Yes, mine had the factory towing package.

[@ArchangelMLM]

The phrase “there’s no replacement for displacement” is actually a lie, because “the replacement for displacement” is weight, always has been and always will be, every mechanic knows this. The GM 5th gen 5.3 (2013-Present) you can get without the DFM system, this is the best option. It’s worth noting that the 5.3-liter displacement V8 first made an appearance in generation three of GM’s small-block engine family. This is due to the fact that these engines are the successor to the original GM small-block 350 V8s dating all the way back to 1955. It’s initially a bit confusing to start with the third generation, but the third generation is the birth of the 5.3.

[@EliteMarineProducts]

I really enjoy your videos, they are nice mix of technical, opinion and testing. My question is, why did GM build a 4cyl. with half the displacement of the 5.3, that gets very similar or less mpg than the "old" tried and true v-8?

They all have issues, they all take your money and they all will break down one time or another. stop bickering over 10s of a second and by what you want. I will only purchase Ford and GM now because of v8's. Untill that changes that is my 2 cents

[@captainron7904]

GM should try making a straight 6 turbo max i would buy something like that

[@big_oucne3536]

don't know if this was already mentioned but this being the sierra rather then the Chevy, and the front ends being different, mpg tests between the trucks despite the same drive line had a varied result which was the Chevy's always getting better mpg due to the rounded front end as apposed to the sierra's more square front. probably wouldn't make much of a difference here but thought id mention it

[@retheisen]

The truck in your rear view mirror was matching you on the acceleration run.

I towed our 22' travel trailer with my 2021 Silverado LM2 Duramax this weekend. I have torque pro app on my phone with an obd reader and I watched several things. One new one was what gear I was in. I have the 3.23 gear and 10 speed in that truck and in tow haul mode, I fully expected it to stay in 8th max gear and it didn't. Several times it went to 10th. Thought that was very unusual.

[@TheGettyAdventures]

It used to be that when in tow haul mode these truck would never enter an overdrive gear but I guess with 3 of them then it makes some sense but going into 10th gear seems a bit much lol

[@slocavky]

@@TheGettyAdventures exactly. That's why I thought it was odd. Ah well. 😂

[@slmjake]

Love your videos sir! My personal experience with an older 5.3 and six speed auto tranny and 3.73 gears is that it was slower than my 150 5.0 and much slower than my powerboost. However with a slide in pop up truck camper weighing about 1800 pounds loaded the chevy 5.3 delivers the best mpgs for some reason. Moreover, that powertrain was bulletproof out to 400k miles but I am a stickler on changing fluids. Love my ford's and my ram Cummins but the 5.3 to me was the best damned darned engine for low cost operations.

[@robertchapman4488]

If the 2.7 had the 10-speed it would be a whole different story.

[@TheGettyAdventures]

Agreed, I think GM should think about giving the 2.7L the 10 Speed.

[@JamesSterling]

If you use KM for distance and KMH for speed why not use metric for weight (kilograms), torque (Newton-Meters), and horsepower (Watts.) At least you would be consistent.

[@bradbowles1153]

I could live with the 2.7 as I only tow heavier loads two or three times a year. I would get the 5.3 for frequent towing.

[@DavidBrubaker-pi4gj]

Hey Getty. So I really enjoy your videos a lot and enjoy your analysis of the tech in the truck industry. I have been wondering what you and other people think about the Turbomax implementation. Its known now that GM was going to come out with a 6 cylinder 4 liter of the 2.7 liter engine that was originally rated for 350 foot pounds. GM decided to double down on the four cylinder model to truely make it a gas with diesel tech in the 2022 refresh. The end result was that it was a bit lacking in power. Do you think that a 5 cylinder would have been better? Smoother operation, a bit more displacement, more overall power for a powerplant that would have been a better one size fits all for a premium midsize truck and full size truck market? I can't help to think how much more horsepower the extra cylinder would provide and the biggest reason is the sound. Inline 5 cylinder engines sound real mean. Thanks for reading.

[@rapidride2]

Think about the wear and work each cylinder has to do.

[@AgonxOC]

Wait didn’t the V6TT from FORD do better than all?

[@irishpotato8816]

I like all these engine options, small turbo engines for people who don’t tow all that often and V8 for those who do tow often. we’re winning as consumers.

[@ht24d64]

This isn’t a real apples to apples test if driveline ratios are different. What driveline was in the Ford ecoboost? Or coyote ?

[@JP-nisu_2]

Why not compare a turbo v8, 3L diesel to the turbo i4?

Makes me wonder how the 2.7 ecoboost compares. I know it’ll beat the 2.7 GM 4cyl, but just curious.

[@stevebeard7667]

I have a 2022 F150 with a 2.7. I do tow occasionally, just pallets after grass or stuff around the house. For me, it's been a really good motor, and the gas mileage is respectable.

[@powerwagon7811]

Great if you want to put a new engine in your truck every five years, or just buy a new one. My 440 Power Wagon is 45 years old and still runs perfect. The greenest truck is the one that doesn't wear out five times.

[@puncht37]

One wonders why GM doesn`t install that 2.7 in the higher trim 1500`s, or the Tahoe/Surburban?

[@ALMX5DP]

I think the target demographic for those models don’t necessarily want it. Might have a bit too much NVH or whatever.

[@TheGettyAdventures]

it is their base model engine so people buying those higher trims might not want it. but it is always nice to have options.

[@puncht37]

@@TheGettyAdventures I believe it`s turbo lag and NVH in a heavier rig. Gm knows this. Even though, the 2.7 has more torque [on paper]. That`s why this vid is cool as it does real world not paper. Old mechanic here also.
