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.

19 HD Longhorn cab.jpg
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.

Never been a GM truck fan, but it sounds like they are doing a good job, I like the cooldown feature. I think some folks under appreciate the need for a cool down after a hard run.
 
TM has to be in there, most likely ramps up to xxx lb ft. That's still pretty impressive especially given the low low first gear a 10 speed trans will have.
 
I wonder if this 910 ft-lbs to the ground in first gear talk is a play on works marketing hype. A Honda civic probably puts 910 ft-lbs to the ground in first gear due to the torque multiplication of the first gear in the transmission and the diff after that. Maybe????

Sounds more believable, ramps up-to...under the right conditions and parameters.

Agreed, still impressive with what is surely a very low first gear.

Good question, though it would seem strange (or not perfectly truthful) for them to use the exact same 910 number.

I dont think that the 1 Gear will be significant lower then it is now, what should that be good for, no need for a granny gear.
They just splitted every gear in two and thats it.
More gears in the middle and upper range means fuel savings as the engine can run most of the time in his most efficient rpm range. And fuel savings is what they want.
 
With 10 gears to work with, I think 1st will be a lot lower. Here are the 6spd ratios for the Allison 1000:
1 2 3 4 5 6 R
3.10 1.81 1.41 1.00 0.71 0.61 (06+) 4.49

I can't find anything on the new 10 spd. but here is some info on the 10 spd for the 1/2 tons.

Model 1 2 3 4 5 6 7 8 9 10 R
Hydra-Matic 10L80 (MF6) 4.70 2.99 2.15 1.80 1.52 1.28 1.00 0.85 0.69 0.64 4.87
 
And that will be exactly the same as our 8HP70 Transmission.
No granny gear.

Agreed, no 'granny' gear, but such ratios/terminology were generally reserved for manual transmissions.
Something like 3.0:1 is lower than traditional first in old three-speeds, and even my '06 V8 Toyota 4Runner with 5-sp A/T has what is/was considered a low ratio first, at 3.52:1. Works well.

Ford's F150 10-speed has a first ratio of 4.69:1, second is 2.98:1, and moving first into the fours makes sense, as it really helps start a load moving.

But we shall see...
 
And that will be exactly the same as our 8HP70 Transmission.
No granny gear.

But your comparing an 8 speed in a completely different application instead of the previous 6 speed in the GM HD pickup. Compared to the 6 speed first gear the 10 speed first gear almost certainly will be lower than anything in the current HD market .

Yes, a supposed beefed up version. I don't know if they left the gear ratios alone or not for the HD version.
 
8HP gear ratios

1 2 3 4 5 6 7 8 R
4.714 3.143 2.106 1.667 1.285 1.000 0.839 0.667 3.300
5.000 3.200 2.143 1.720 1.314 1.000 0.822 0.640 3.456

I'd say that those are very low first gears (by any traditional/historical measure) for an automatic transmission. They probably pull and work well.
My 6-speed manuals are still my preference.
 
And what is the benefit of a such a low 1 gear on truck that shoves 1000ft/lb into the transmission?

I would have missed that decades ago in our under powered euopean vehicles, but here?

I never felt that in my old 48RE equipped Truck the 1 gear was to long, the problem was and is 3-4.
 
Less stress on the driveline would be a good start, another would be less heat load from the torque converter (less fluid shear).

I suppose if you drive like a tool and stand on the throttle from a dead stop these benefits would be mum, but for the average driver I can see the advantages. Especially when towing off the hard pan, I've had to grab the low side of the transfer case quote a few times because 1st in 2whd or 4 hi is a little too high for those situations.
