2020 RAM 1500 Rebel 4×4 EcoDiesel – Bottom Line Review

2020 RAM 1500 Rebel Crew 4x4 TDi: Rebel yells with aggressive trim darkening, two-tones and skid plates

FOOD FOR GRUNT: A breakfast of oats is good for a horse, but for more grunt alfalfa offers extra carb energy. Feeding a internal combustion work engine diesel provides 15% energy density than similar meal of gasoline. Thus, when it comes to heavy duty work trucks large displacement diesel engines outsell their gasoline powered counterparts by a margin of 3 to 1. It is not so where light work and recreational pick up trucks are concerned, however that is about to change.

FOR THE LONG HAUL: The day may come when high torque electrification can affordably yield 1000 miles of highway range in light work trucks. Until then new turbocharging, high pressure fuel injection and clean diesel technologies bestowed on “smaller” displacement powerplants hope to invert the half ton gas to diesel sales ratio. In fact, model year 2020 marks the first time each of the Big Three offers a turbo diesel option in their 1500 series pickups.

HALF TON BIGHORN OIL BURNER: FCA (soon to be Stellantis) launched a smash hit redesigned RAM pickup truck in North America for model year 2019. From the get-go a 48 V light hybrid eTorque assist has been available on gasoline engines. However this year marks the return of gobs of low end torque in a RAM pickup. Roadblazing.com editors had the privilege of donning plastic gloves to pump from a grimy gas pump into a 2020 RAM 1500 Rebel 4×4 Eco Diesel.

WHAT: 2020 RAM 1500 Rebel Crew Cab 4×4 EcoDiesel. One year ago the 5th generation of [formerly known as Dodge] RAM pickup truck was unveiled to the North American market with a designation code of DT, replacing the

Standard Powertrain: 3rd generation VM Motori L630 intercooled turbocharged 3.0L 24V DOHC compacted graphite block Tier 2, BIN 3 EcoDiesel V-6, with liquid intercooled Honeywell 2056 variable geometry turbocharger, NOx exhaust particulate filtration and urea injection after-treatment + 8-speed torque converter planetary automatic transmission + 2-speed part time electronic transfer case 4-wheel drive to an open front & E-limited slip rear differentials.

  • 260 horsepower, 480 lb-ft torque @  = +20 hp, +60 lb-ft vs. Gen. 2 L 630 EcoDiesel
    • vs. Chevrolet Silverado 1500 3.0 I-6 TDi  = -17 hp, +2- lb-ft; vs. Ford F-150 3.0 V-6 TDi = +10 hp, + 40 lb-ft
2020 RAM 1500 Rebel Crew 4×4 TDi: 260 hp / 480 lb-ft = +13% / +9% over the previous iteration VM Motori 3.0L Ecodiesel

WHAT (A) STYLING DIFFERENCE: The “Big Rig” engine forward, low slung fenders with low mount headlatmps and tall cross haired grille began with a 3rd generation Dodge Ram DR series, muscularized for the 4th generation DS series Ram.  A new 5th generation RAM 1500 pickup adopts a more “aero” approach with taller fenders and headlights positioned on the flanks of a no longer crosshaired multi horizonatal slat upper grille.

2020 RAM 1500 Rebel Crew 4×4 TDi: Rebel yells with aggressive trim darkening, two-tones and skid plates
  • “RAM REBEL” theme = darkened grille w/ dark lattice inserts; Dark plastic simulated hood vents; darkened bumper covers & lower fascia; Exposed front lower skid plate; Darkened window frames & mirror caps; Two-toned darkened lower body; Larger dark wheel arch cladding; Two-tone alloy wheels; All terrain tires; Left rear tailgate “REBEL” emblem.

WHY: Small displacement, big torque diesel power rejoins this revised, ultra-civilized civilian pickup truck

WHEN: On-Sale (in the U.S.) since Spring 2020

WHERE: RAM new truck dealers

WHERE MADE: Sterling Heights, Michigan, U.S.A.

WHERE TO: High four-wheel drive on the fly is but a twist of the electronic two-speed helical gear transfer case selector knob. Where improved roadway ends, the air-suspension provides about an inch greater wheel articulation while light truck knobby Goodyears grab the dirt.

  • -1 No driver selectable automatic terrain modes

HOW STRONG: A paradigm of automatic gear-swap confidence the ZF 8-speed transmission doesn’t concern itself with sub 2000 rpm suburban or highway cruising. The Honeywell turbocharger’s variable geometry vanes spool up attentively to throttle demand. Even at slower crank rotation the compacted graphite block DOHC oil burning V-6 transmits barely any idling clatter to a calming crew cab cabin.

HOW LIMBER: Optional air springs at each corner stand in for standard coils relaxing the ride without the typical debilitating bobbing, and can be set to lower the RAM 1500 Rebel’s height. Combined with active grille shutters this drag reduction helps slow the fuel sipping. Even equipped with tall sidewall all-terrain rubber steering turn-in witnesses and improvement over old and helm winding effort wouldn’t be out of place in a large SUV. Single piston sliding brake disc calipers offer progressive reaction.

HOW FAR: 24 mpg combined fuel economy = 20% > gas Super Duty 2500s; = 20% > RAM 1500 Eco standard duty gas V8 powered half-ton out there. 957 miles highway range with optional 33 gallon clean diesel tank.

HOW BIG/ LITTLE:  Almost as large as boats it will tow; Holds five big grown-ups wearing their Carharrt and steel toed Timberlands;

The metallic banded twin analog ELD gauges, steering wheel and tandem white contrast stitching throughout are classy pieces. So are the jewel finished lower center stack trailer / bed toggles.
