Ram and Cummins have skipped the nickel-and-diming for the 2019 ratings war, going straight to 1,000 pound-feet and a top tow rating in excess of 35,000 pounds. There’s plenty of other stuff too, but you’re going to hear those numbers a lot.

19 HD 4_1k Cummins.jpg
19 HD CGI.jpg
The new 6.7-liter Cummins is built on a CGI (compacted graphite iron) block—lighter, stronger, quieter and proven. Bore and stroke are 4.21x4.88, the compression ratio on the standard output is 19.0:1 while the HO is 16.2:1 and virtually everything else is different: rotating parts, pistons, head with improved exhaust braking performance, injectors, high-pressure pump, entire air-handling system, turbo…and the display wasn’t marked but it sure looked like an EGR cooler top right side. There’s more aluminum where it makes sense—water pump housings, brackets, etc.—and it runs on a dual-core processor.

Standard output is 370 horsepower (at 2800 revs) and 850 lb-ft (@1700), the HO engine is 400 and 1,000 respectively (peak torque occurs 100 rpm higher than the SO engine), and Chassis Cab trucks will get the updated engine so expect an increase when that appears in Chicago next month. Those are the only ratings…there’s no manual gearbox rating because no manual is offered. Ram noted with an ever-declining percentage (less than 4% recently) and fiscal responsibility said don’t spend developing a new manual gearbox, though I’m sure Cummins has the ability to deliver a “de-rated” engine package that could match the current manual gearbox capacity.

Both the 68RFE and AS69RC have been lightly upgraded, much work around engine integration with the dual-core processor aimed at better drivability. Both these transmissions are diesel-only and run by column shifter; all gasoline HD trucks run the 6.4-liter and a ZF eight-speed automatic with the rotary shifter. Power Wagon still has a transfer-case lever on the floor, and the eight-speed gives it a crawl ratio of 50:1.

The Max Tow package returns and brings with it larger rear rotors, a 12-inch ring gear, bigger bearings and shafts, the latter requiring a larger bolt circle, so whether or not you get Max Tow every dually will have a different bolt pattern than SRW trucks. With Cummins power, only the MegaCab 4x4 2500 has a tow rating of less than eight tons.

Of course cooling is upgraded too, the radiator taller, 39 inches wide and the grille opening 30% larger. Despite the added cooling aero drag has dropped by eight percent, in big part from the airdam and active grille shutters (all engines).

Everything else underneath will look familiar but not identical. The new rails are fully boxed, crossmembers stouter, 63 ksi steel used for the gooseneck mount, axles and brake calipers larger, springs a bit further outboard, shocks are monotube frequency selective dampers (except Power Wagon’s Bilsteins) hydro C-pillar body mounts and active mass dampers from the 1500, exhaust hangars different, the basic claims being stronger, quieter, and more refined. If I didn’t hear “capability” once a minute I didn’t hear it at all.

Though it’s all been massaged suspension configurations parallel the current truck, with the full-air 2500 and auxiliary-air 3500 options.

Last year’s bed and cab structures get a new tailgate, bumpers, front clip and mirrors, but the mirror mounts remain the same. There are at least four styles of lights and grilles, at least seven new wheel designs and a factory bed step option. Those mirrors now offer cameras (for the aerial 360 image), LED rear facing spotlights and power convex sections on the towing units—linked to the driver memory system if you get it.

Those bodywork changes plus active grille shutters on every powertrain yield a claimed 8% aero improvement, with the bumper/airdam area getting credit for almost half that: the coefficient of drag on a 2WD Quad Cab short bed is 0.409, and, thanks to an aluminum hood, revised bumpers and some other changes the truck is 143 pounds lighter: A co-pilot without exceeding GVWR.

Inside, the cabin is virtually lifted from the 2019 1500 model, including the real leather, wood and metal trims, a unique key fob for Limited trim, and the 12-inch tablet screen to echo a pair of stacked 8.4s. The Ram comes with active noise cancellation on all drivelines and is said to be 10 dB quieter than the old one, all the better for sampling the 17-speaker, 750-watt optional Harman/Kardon sound system. Headrests are now four-way adjustable—though I missed checking the center rear, multiple type-C USB ports allow charging at least three phones at once, Uconnect supports Waze and Google maps, the Power Wagon has a forward camera for trail use, there’s trailering reverse guidance, a trailer-mount backup camera with independent 12-way connector and tire-pressure monitoring for up to 12 tires on four different trailers.

Ram attributed the early availability of uncamouflaged tester photos to three items: One, it helps build awareness and interest. Two, it saves thousands of dollars on camo. Three, it lead to more than one-million miles of real-world testing and loads. They also pointed out that Ram 3500 has the highest rated resale value, while an article I read en route names Ram 3500 reliability “well below average.” Damn statistics.

Expect 2019 HD Rams to roll into dealerships in April or May so you can find out yourself.

There are a few departures in this new Cummins that make me think they are trading longevity for cost reduction and/or NVH reduction for the people who think a truck should be a Cadillac.

1. I am really bugged by the CP4. There are zillions of hits on a google search of catastrophic failures taking out the entire fuel system, class-actions trying to get underway, etc. I am baffled that Cummins would risk such a black eye, given the terrible history of that pump. Maybe TDR staff can pin down an engineer about this???

2. The engineer in one of the videos mentioned the hollow cam, and the scissor-gear driving it. Here we go again with a potential internal failure point introduced for the Cadillac crowd. A gear with moving parts. I know variable valve timing, and cam phasers, etc have been around a while, but I again see longevity being traded away.

3. Roller lifters. I was never bothered by the need to do an occasional lash adjustment. While I am OK with going hydraulic, I again view rollers as a trouble spot. Look at the cam failures showing up in the Hemis, and it is generally a roller that failed, and destroyed the cam.

I was all revved up to get a 2019, but am having serious second thoughts.

Ha I though the same thing...the new killer scissor gear...how many cycles can that spring take on the scissor gear in the real world.

I wonder if the commercial OEM applications of the 6.7 will have the scissor gear? Then again, someone had pointed out that the Ram application is the only one with the gearcase in the front, so probably not.
 
Time will tell. I have always been one to forego the very newly redesigned powertrains until the bugs get worked out and the powertrain is proven. 2021-22 will be my next ruck unless somebody makes that decision for me via collision.:eek:
 
I was looking at International and Freightliner medium truck engines today. The L9 Cummins looked interesting.
 
I was looking at their website this morning and I have to say im a bit disappointed. Either they have not updated their website in a number of years or they are truly indoctrinated ala EPA....



On a lighter note, hydraulic valve lash, no more overhead checks. I'm guessing this is Cummins push to a lighter grade oil for the 6.7.

I'm willing to bet that Cummins is trying to get ahead of the trend to drop the Zinc additive from lube oils. The feeling is that the zinc getting past the piston rings and valve guide seals is contaminating our Catalysts. Todays low Zinc oils have already taken a major toll on gas engines with flat tappets. Almost all new engines today are a roller type as a result. The self adjusting feature is just a plus.
 
I know I am in the minority, but love driving my manual transmissions, likely will keep the Cummins trucks I have for a while.

I hear you brother! Lucky for me the manual was offered on my 2017 3500 truck when I bought it...to tell the whole truth though, I had a choice of two 3500's on the lot....basically the exact same truck even up to the color. But the manual was close to $3,000.00 cheaper so I went with it (lucky my father insisted years back that both my brother and I learn to drive on a manual transmission....according to him, you really don't know how to drive unless you can handle a manual). I knew this time would come when the last of the Big 3 would say goodbye to the manual transmission....I was just hoping that they would still be offered until at least 2020. Oh well......

I've thought a few times about buying a 3500 (with G56 while I can), but have been really happy/impressed with the 2500, so I'll just not spend that money and enjoy what I have.
 
I just saw yet another interview with a GM engineer who states the new Duramax/ten speed combo gets full torque right out of the gate. I guess it's for real. Should be interesting.
 
Why is the 2020 Chevy being compared to the 2019 RAM lately? They say the Chevy with 35,500 towing weight is the new king of the trucks. I guess you can say that but the 2020 RAM and Ford will "probably" be higher.

Because Ram is so late with this introduction, I guess. We are roughly half way through the "traditional" 2019 model year, and the trucks are still a month or two away.
 
You mean no TQ Managment?
I believe that if I fell it with my own back.
I can only assume they mean no torque management, but their terminology is "full torque available in first gear". Does that mean there is no torque management? Does it mean it's available as long as your right foot is not too frisky, or it will intercede? I have to believe it is the latter, or there will be carnage.

I dont think so, the Torque that engine sends into the Drivetrain would make a Screw out of everything behind the transmission itself.

Check out how axles and driveshafts are built in a Class8 that has the same Engine Torque Value. Double or even Triple in Size.
Without TQM even our old Gen3 would Twist a Corkscrew.

Small math, 1000ft.lb x5 in 1 Gear would give a whooping 5000ft.lb that goes onto the Pinion and incredibly 17000ft.lb onto the halve shafts, and to finish it nicely we use Low in TC then we have around 45000ft.lb at the wheel.
If GM didn't invented a new miracle highstrenght Material that is also lightweight - then don't believe in any Internet rumors about Tq Management or not.
All these high powered trucks need the TQ Management like we humans need the air to breathe.
 
From a Motor Trend article:
That bests the 1,000-lb-ft Ram by one (400-pound) sumo wrestler. GM reps were also quick to brag that, although 910 is undeniably less than 1,000, at least the GM powertrain can put all 910 of its torques to the ground in first gear, thanks to the aforementioned driveline component reinforcements (subtly implying that the other brands' trucks are torque-managed to some lower number in the lower gears—an aspersion we've yet to confirm).

From Equipment World:
With all of the upgrades, McQuaid says 2020 Chevy HD trucks will deliver all 910 lb.ft. of torque to the pavement in the first gear. The transmission is also capable of first gear lockup with all 910 lb. ft.

“That really saves on the heat,” says David Ames, assistant chief engineer on the trucks. “And part of getting to the 35,500 mark is getting rid of the heat when you’re there.”


Skip ahead to the 4:30 mark:

I tried to listen carefully, maybe I missed it...

while I did hear them say to 'put the torque to the ground', I did not hear them say in first gear or all gears.
