Dodge / Ram
by David Zatz
Most of the Power Wagon’s 2014 specs continued into 2017, including the segment-exclusive front axle disconnect system and “Ram Articulink” setup with high movement joints at the control-arm-to-axle mounts and disconnecting sway bar. Water crossing remains at 30 inches.
The ramp travel index is 510, with a full 26 inches of suspension travel with the “Smart Bar” (sway bar) engaged, on the 2014-17 Power Wagons. Figures are from Ram.
The rear suspension is similar to other Ram 2500s, with Jeep’s five-link coil design, providing a payload up to 1,490 pounds and towing capacity up to 10,810 pounds.
The sole engine is a 410 horsepower 6.4 Hemi pushing out 429 pound-feet of torque on regular gasoline. The 392 cubic inch engine has 10:1 compression, and takes seven quarts of oil and 16.6 quarts of coolant; redline comes at 5,800 rpm.
The Power Wagon has a Borg-Warner 44-47 electric part-time transfer cases (also used on the regular 2500), with a low-range ratio of 2.64 resulting in a crawl ratio of 35:1.
Rear axle shafts were upgraded to 38 mm. Both axles have electronic locking differentials with electro-magnetic actuators.
A 180 alternator is standard, with an optional dual 220+160 setup for 380 amps total. The battery is a Group 65 with 750 cold cranking amps, a bit higher capacity than the standard one.
Front brakes have 14.2 x 1.5 inch rotors with twin-piston pin-slider calipers; rear brakes have 14.1 x 1.3 inch rotors with similar calipers. Power assist is dual-rate using a tandem diaphragm vacuum. (These specs are the same as with the standard Ram 2500.)
The steering still has hydraulic power assistance. Turning diameter is 44 feet on the short-bed and 49 feet on the long-bed. The wheelbase is 149 inches on the short-bed, 169 on the long-bed. The Mega Cab has a 6’4” bed, 160 inch wheelbase, and 47 foot turning diameter.
Four Wheeler compared four 2015 pickups, and found that Power Wagon easily dominated Chevy and Toyota models (it also had the top interior and exterior ratings, by a large margin on both):
The 2017 Ram Power Wagon is backed with a five-year/60,000-mile transferable powertrain warranty covering the engine, transmission and drive system, with towing if needed. There is also a three-year/36,000-mile basic warranty for other parts.
The 2017 Ram Power Wagon is built at the Saltillo Truck Assembly Plant in Coahuila, Mexico and will be available in the fourth quarter of 2016.
