When you’re towing in excess of 20, 30,000lbs, torque is king. 600lb-ft works, 1000 works better. And all things being equal, more torque is more reliable and in theory more economical; if you only have 600ft-lbs, the engine has to work harder to maintain 70 where 1000 doesn’t. This is all prefaced by saying with torque limiters and tuning, you’re not rolling around with 1000ft-lbs. It’s capable of making that….

I’d love to see some fully loaded 60mph to 10mph test, or 40 to 10 test…. Also towing in rolling hills changes the game completely to, the engine transitioning to no engine brake to full engine brake up and down, that’s when tuning plays a big part in overall performance, I’d definitely be curious to see how the big 3 stack up in tests like these. Just throwing some suggestions out there, keep up the great content, hope to see more coming in the future.

The problem is, more powerful or less powerful all diesels have to emission equipment and DEF from the factory by law and that's a big part of where the asinine cost of modern diesel engines come from. So if Ford for example, we're to offer a significantly detuned PowerStroke that made say 350hp and 750ftlbs of torque, it would still probably cost just within a couple thousand dollars of it's HO 500hp/1200ftlbs of torque version and when people are spending at minimum 65K on a vehicle, they will probably just opt to get the most powerful engine available if the cost differential isn't very big. Honestly I think Ford has the right idea with the 7.3L gas engine. It's relatively low output for it's high displacement means it's an under stressed engine that should have no trouble lasting decades into the future and because it's a naturally aspirated gas engine it's far less complex and expensive to purchase and maintain than any modern diesel, aside from all that it's 430hp and 480flbs of torque is plenty for like 90% of what anyone should be doing in a 3/4 or 1-ton truck anyway.

That is crazy, my Detroit DD13 is only set at 435HP and It's 12.7 Liters. I think the Duramax 6.6 does good the way it is , i can't imagine 600 HP In a 3500 HD let alone that kind of torque. Grandpa will have no problem getting the camper to the campground.

@@midengineZ06 I’m reasonably sure that, with ag & construction equipment, “size matters”. So, once the engine gets large enough the emissions restrictions are loosened enough that they can get away from some of the equipment required on smaller displacement engines. I can’t say that’s entirely for certain, though. I do know manufacturers have been able to put out some equipment without having various emissions equipment while still having “mid-size” displacement engines. I didn’t really dig into the details of how they were accomplishing it, though. I know the general idea of decreasing compression ratio = lower combustion temps = lower NoX, but that’s also going to take away from performance and won’t completely eliminate NoX without egr or def/scr(diesel of course).

I have a 2020 3500HD Denali DRW. I bought it to tow a 2020 Jayco North Point 377 RLBH. The trailer is a little over 17000 lbs loaded and is just shy of 43 feet long. This truck handles this trailer with very little effort. The Biggest things that I can tell you that GM Really needs to be doing is partnering with Banks right from the factory and automatically putting the Derringer, Petal Monster, Ram Air Intake, Differential Cover and the Turbo pipes on right off of the rip. I will be adding these things to mine. Even if they do not bring banks on board, DIC needs to have a built in Code reader and also have all of the relevant data available in an App on the screen. There needs to be a factory option to place the truck in Regen Mode manually. I would absolutely go for the 8.3 because knowing that my L5P does not even break a sweat towing my fifth wheel now, the bigger engine would do it even better with better efficiency.

I never thought of them getting into making small semi trucks. But the world is changing. Buying a semi truck to haul the more weight or drive in comfort with better ride with less hauling weight

I get everyone wants more oomph, but considering Companys usually down tune the same engine thats in a 2500 & 3500, for 4500/5500/6500 (even Ford with the F600 and F750, detuned 6.7 to bridge the gap between Medium and Heavy Trucks while maintaining reliability).

If there is an 8.3L engine coming, I doubt it's coming to the 2500/3500. The 6.6L has the ability to make even more power, but GM is apparently choosing reliability. We know this because Banks took one over 1000 hp. Banks also has a close relationship with GM, and I'm pretty sure GM took that research and put it into the current revision of the 6.6.

The l5p is a stout engine, lots of guys including myself running large fixed vane turbo setups making 7-800+ hp

8:20 Talk about the Edison Motors truck conversions with the diesel generator electric motor “hybrids.”

I can see an Edison style truck with E-axles and a smaller engine. That system seems to have peak efficiency without the need to cut all the gears to make a 10speed.

Lots of info here. Duty cycle is never spoken about. The rpm at which these engines make their max torque is also never an rpm at which you'll have your foot to the floor and actually operate these new trucks at. If you had a manual transmission behind these engines your drivetrain would explode. ALL of the older trucks were making 450-500 and 600 ft lbs and had a manual trans to allow pulling a hill at 1600 rpm to feel that torque and spin that turbo! I miss that so bad. example, 2006 ford f350 6.0 (fixed properly) with a zf 6 speed, 4.10 gears, loaded up was the best towing feel. That turbo and exhaust sounded so good!!! you could feel the Torque!! lets all join together and make towing fun again!

That's great news! But what about the big gas V8 they were supposedly working on to compete with the 7.3 Godzilla?

In the 80s there were Cat 18L V8s(3408) and Cat 16L I6 3456. Mack had the E9/EE9(16.3L). Biggest North America on road engine is the DD16(15.8L) and then the Cat C15(not C-15/3406 at 14.6L) at 15.2L. The D16 is a 16.1L I6. I don't recall any others over 15L. Cummins X15 is a 14.9L X12 is 11.8L X10 is new for 2025 Volvo D16 is 16.1L D13 is 12.8L D11 is 10.8L D17 is new for European market Detroit Diesel DD16 is 15.8 DD15 is 14.8L DD13 is 12.8L PACCAR MX13 is 12.9L MX11 is 10.8L International/Navistar A26 is 12.4L S13 is 12.7L

As cool as a new 8.3l would be, I would rather they focus on the following: An exhaust brake that works as well as Ford or Dodge Bigger brakes A larger fuel tank 36 gallons doesn't cut it when towing 20k lbs Better DPF system Super cruise on the HDs But yes 500hp and 1200ft-lbs would be awesome after other improvements. My 2019 l5p has enough power to pull my 20k lb trailer without issue.

That makes me happy to hear this might happen this is great

I hope you guys are looking at Edison Motors. I think they have the best idea for future hybrid diesel power. Roman mentioned this and I think it's worth looking at.

GM built an 8.1 gasser it will run and all but when gassing on it need to be pulling a fuel tanker behind it.

Yes yes yes I would buy one tomorrow I hope they build it great job guys

My guess is it's all about power potential. Large bore size generally makes emissions worse (all else being equal) as flame travel is longer. But I'm not a diesel guru and compression ignition may be less handicapped by that than gas. You guys should go interview the Canucks at Edison Motors. They are doing diesel electric development up in BC.

That's what I was thinking. No need for it in the pickups.

I think applauding them or giving them the thumbs down is too soon of an action to take right now. They could come out and somehow develop brand new technology and make a bigger engine making 30mpg…we don’t know what we don’t know

I am surprised that no hybrids were developed yet. I understand fuel efficiency is probably third to power and reliability. It is done with locomotives (though in a different way), I am surprised diesels don't have this yet. Even regen braking before exhaust brake would charge the battery really quickly.

Check out Edison motors out of Canada. They are building a diesel electric hybrid.

Those numbers don't add up. A deleted & tuned duramax L5p can easily hit 600HP & 1200 torque. Take all the crap off these trucks & not only will they perform better, they'll be more reliable, too.

Is it really fair to call the DMax “long in the tooth”? Just because the displacement has not changed since 2001 doesn’t mean the engine design hasn’t. L5P is a VERY different engine vs the LB7.

They don’t have huge inverters because they don’t have enough alternator. A dual alternator setup with 400A output is only 4800w. They’d need something more like an e-torque motor-gen or Powerboost inline motor-gen to get enough output

Too bad GM doesn't use this effort and money to perhaps make their existing models more reliable.

And what transmission is going to deliver the torque and horsepower? All three HD diesels are detuned to protect the transmission. I don't see where this makes any sense. Good point on the generator though.

Exactly! I don't need all of the electronic bullshit and cameras to help me tow better. I came from a generation where we had common sense and actually knew how to drive and haul things. Prices of vehicle of any type are way over priced. There is no reason other than greed and broke people trying to keep up with the jones's are why these vehicles are so expensive .

Wow. This is really surprising. Could it be that this is going to be strictly a medium duty truck engine? Kind of like Cummins making engines for semi trucks, medium duty, and passenger pickups? An 8.3 liter is a huge diesel engine for a passenger pickup. Will GM still offer the 6.6 liter as an option? If GM (Isuzu?) is going to do this, of course it'd be for horsepower/torque numbers, but I think they'd also be doing it for reliability. They probably could get huge numbers out of their current 6.6 liter, but an 8.3 liter wouldn't have to work as hard to get those same numbers, which is smart. Great video guys.

Post office trucks are galvanized too I think. Galv plating HD trucks is a good idea.

I was thinking more along these lines also-

I’m sure someone has already said this, I scrolled down a long way, did not see but did not go to end of the comments. Cummins has been running a 8.3 since the 90’s in Class 6 trucks. HP and Torque not close to what’s out there now, but I’m sure a little tuning would bring that inline 6 to today’s standards. Cummins now has engines in motor homes that exceed 8.3 that easily dropped into a 5500 application. 3500’s have been limited to 14,000 GVW. My Fifth Wheel PIN Weight overloads my 16 Ram and exceeds its GVW by 400 lbs. I tow with a 650 Cat Powered SuperCrewzer. The Dodge handles the trailer as good as the 650 in most all respects. Fuel mileage is about one mile per gallon difference to the Dodge running in 5th gear at 2200. 4:10’s in the rear of the Dodge. The Ford with all its HP and Torque would not help me as the 350 is still limited to 14,000 GVW. Also, scrolled down in your channel vid listings, can’t find anything more about your testing pre recall on and recall Cummins info. Like you pulled it off your channel list. That needs to be pinned.

Thanks guys Nothing earth shaking - its sort of like Cummins 9L used in RV's about the same HP and torque, just bigger jugs! The problem is the little 10speed Allison for the 6.6 will not hold the torque of a 8-9 L engine. One thing for sure this engine will not blow any Cummins out of the water or road. The 8.9 and 9L are icons in the trucking industry. Mike

Are they going to fix the issue with the harmonic balancer shearing the locating pins by using a woodruff key instead?

8.3 means high output and longevity? 6.6l is still plentiful to pump 1200 lb ft tq!

As a duramax assembly supervisor, I can say it very much might exist. It'll easily be one of the duramaxs of all time!

You will need the Ike Gauntlet version 8.3 , Mega Ike Gauntlet, or Mega Max Ike, awe forgettaboutit. Thanks for the update,, have enjoyed TFL for years now. Thanks

Free advice for GM Product Managers: The latest 6.6 duramax is plenty... Id rather have a bigger fuel tank, Supercruise on HD, the ability to Bluetooth any accessory camera into your camera views (say the rear of an rv), a special Google maps that takes your trailer size, weight, height and routes you ways that avoid lower obstacles, also team up with Starlink and offer a 6 month subscription to THAT instead of xm, then add auto window up and door unlock on rear doors, and maybe a price cut for gods sake! Otherwise the new truck is phenomenal ❤

I think the biggest benefit of the 8.3L is that it would give GM room to grow, in terms of HP and torque numbers, in the future.

A move away from batteries, is a great idea.
