2019 Ram HD Pickup Truck – Cummins Diesel Has A thousand LB-FT of Torque – Car and Driver

With all three of the indispensable gamers within the heavy-accountability truck segment offering diesel pickups that have crested the 900-lb-ft torque plateau, it used to be only a matter of time except thought to be one of them eclipsed the magic A thousand-lb-ft imprint. The 2019 Ram Heavy Responsibility is the principle to dispute the title, attributable to a carefully transformed model of the feeble Cummins inline-six turbo-diesel. Hitting the A thousand-lb-ft dimension correct on the pinnacle in its high-output configuration, it enables a Ram 3500 traditional cab 4×2 long-box dually equipped with the Max Tow bundle to pull a ridiculous 35,a hundred kilos or lift a 6570-pound payload. But there’s more to the memoir than correct raw speak.

Air Springs and Excessive-Energy Steel

The truck is really novel from the bottom up, constructed on a novel frame that makes intensive utilize of high-energy steel—ninety eight.5 percent, per Ram—for improved energy and weight financial savings, with six crossmembers and fully boxed rear sections. A pair of Active-Tuned Mass Modules comparable to those feeble on the 2019 Ram 1500 support dampen vibration. Suspension upgrades encompass novel, stronger and lighter front and rear axles, plus modern springs and upgraded bushings. The 3500 one-ton has rear leaf springs, whereas the 2500 three-quarter-ton retains the coil-spring setup. Rear air springs are on hand, with the 2500 setup changing the old fashioned springs with a pair of air springs. The 3500 dietary supplements the leaf springs with air luggage, allowing the engineers to spec a smoother-riding leaf spring when the truck is unladen. Three modes of operation rating a watch on the air springs: Accepted/Payload automatically detects the weight and adjusts the springs accordingly, Trailer Mode enables the bed to lower about an slump to defend a stage relationship with the trailer, and Bed Mode permits lowering of the bed to simplify trailer hookup or ease loading.

Riding atop that frame is a freshly restyled physique that beneficial properties an increased amount of high-energy steel, which, blended with an aluminum hood and other weight-saving measures, contributes to a claimed 143-pound total weight reduction. Engineers strived for a sleeker profile and managed to reach out of the wind tunnel with a Zero.forty one travel coefficient, the lowest ever for a Ram HD. The bodywork is spellbinding, too, sharing no panels with the currently refreshed Ram 1500. Blended with novel engine mounts, hydraulic physique mounts on the C-pillars, active noise cancellation, novel employ parts, and the aforementioned vibration dampeners, Ram says it has reduced the ambient inside of sound stage by 10 decibels, a dispute we’re going to gladly pronounce when we take a look at one.

Huge revisions were additionally made to the electrical machine, including two on hand twin alternator setups to be obvious that the total most up-to-date tech beneficial properties, instrumentation, and accessories just properly and to guarantee a great deal of vitality and junction parts for upfitters who reconfigure the Ram chassis for industrial and emergency-automobile utilize.

The inside of continues the designate-huge uptick in positive and refinement started by the currently redesigned Ram 1500, emphasizing a novel instrument panel, upscale provides, and a revised HVAC machine that strikes a better volume of air whereas simultaneously lowering noise. Electrical heating aspects on diesel fashions lag up the shipping of heat air on cool mornings. The redesigned heart console gives ample storage dwelling to construct a 15.Zero-slump laptop out of gaze and gives three USB ports in front and two in abet for a entire of 5; three of them, including one in abet, focus on with the Uconnect infotainment machine. A 5.Zero-slump masks is traditional; an 8.Four-incher is optional, as is a fully configurable 12.Zero-slump masks with odd graphics keyed to particular person Ram fashions.

Powertrains Built for Towing and Hauling

Taking a peek deeper into the powertrain, the lineup starts with a naturally aspirated Hemi 6.Four-liter V-8. (The old injurious engine, the 5.7-liter Hemi, has been removed from the lineup.) Rated at 410 horsepower and 429 lb-ft of torque, the 6.Four sends its output to the maker’s 8HP75 eight-lag automatic transmission made by ZF. Beefed up for HD accountability with additional planet gears for two of the gearsets, a reinforced torque converter, and a heavy-accountability parking pawl, it uses sixth gear as insist power and seventh and eighth as overdrives. Interestingly, the Ram HD’s maximum payload pick of 7680 kilos is earned by a conventional-cab long-box 3500 dually model equipped with the 6.Four gasoline Hemi V-8. Or no longer it is miles not that the diesel couldn’t tackle the weight, nonetheless the gasoline engine’s lighter weight contributes much less to the scandalous automobile weight ranking.

Revisions to the Cummins 6.7-liter inline-six turbo-diesel are vital. Ram claims the novel engine is 60 kilos lighter than its predecessor. Fresh pistons, acknowledged to be lighter and stronger, produce the most of low friction rings and hump on novel forged connecting rods in a novel block made of compacted graphite iron. The novel forged-iron cylinder head is house to novel rocker palms, employ valves, and springs. Compression ratio for the usual output is 19.Zero:1; the high-output model uses a lower 16.2:1 ratio to facilitate additional enhance. Talking of which, the improved variable-geometry turbo mounts to a novel employ manifold and is ready to delivering as a lot as 33.Zero psi of enhance; the intercooler has been enlarged to the level where Ram calls it the greatest ever marvelous for its diesel pickups. The redesigned gasoline-shipping machine beneficial properties a novel pump running at 29,000 psi. The in fashion-or-garden-accountability model is rated at 370 horsepower at 2800 rpm and 850 lb-ft at 1700 rpm; the high-output model clocks in at four hundred horsepower and A thousand lb-ft at 1800 rpm.

Shifting duties for the usual-output 6.7-liter diesel plunge to an upgraded model of the six-lag automatic transmission feeble previously. Shift positive is alleged to be improved via variable-force solenoid controls for the torque-convertor snatch, and a novel reverse accumulator improves shift actually feel when going from park to reverse. Extra hydraulic aspects were tweaked to comfy the shift from power to park. Investors opting for the high-output diesel opt up an Aisin six-lag automatic transmission with a better thrust bearing and additional heat treating for instruct parts.

Choosing four-wheel power brings a trio of switch-case choices. The 6.Four-liter Hemi gasoline V-8 and traditional-output 6.7-liter diesel powertrains produce the most of a BorgWarner switch case with both a handbook (BW-Forty four-Forty seven) or electric (BW Forty four-Forty six) shift. The low-vary ratio is a 2.Sixty four:1 reduction. Harnessing the mountain of torque from the high-output Cummins requires the talents of the novel and hefty BorgWarner piece-time switch case (BW Forty four-48) that is designed to face as a lot as the 3500’s tow ranking of 35,a hundred kilos when equipped with the Max Tow bundle (trailer-brake controller, cargo-inquire of camera, fifth-wheel hitch, 12-slump rear axle with a Four.10:1 ratio gear space, better bearings, twin rear wheels, and a pair of additional items).
