HEMI or Cummins: How to Spec the 2027 Ram Power Wagon

A Power Wagon buyer in Nova Scotia usually already knows the truck can handle rough ground and heavy loads. The harder call is the engine underneath. The 2027 Ram Power Wagon comes with either the standard HEMI gas V8 or the Cummins turbo diesel, and that single choice changes how the truck tows, climbs, and feels every day.

This guide breaks down what actually changes between the two builds: power delivery, trail geometry, cabin tech, and which driving habits point toward each engine before you order.

2027 Ram Power Wagon: Shared Specs and Engine Numbers

These chassis numbers stay the same no matter which engine sits up front. Only the output at the bottom of the table shifts with your engine choice.

Engine Character: HEMI V8 versus Cummins Turbo Diesel

The Cummins is a 6.7 L turbocharged inline-six diesel rated at 430 hp and 1,075 lb-ft of torque, and that torque arrives low in the rev range. It lets the Power Wagon pull a loaded trailer away from a stop without hunting through gears.

The standard HEMI gas V8 trades some of that low-end pull for a lighter nose and a quicker-revving feel. It suits drivers who spend more time on rock ledges and less time hitched to a trailer, since a lighter engine changes how the front end reacts on uneven ground.

• Cummins turbo diesel: 6.7 L I6, 430 hp, 1,075 lb-ft of torque, standard sport performance hood and Cummins fender badging
• HEMI gas V8: quicker-revving feel, lighter front end for technical trail driving
• Shared on both: 8-speed automatic, 4WD, 3.42 axle ratio, three-link front suspension with electronic-disconnecting sway bar and five-link coil rear

Off-Road Geometry and Suspension

The three-link front suspension with an electronic disconnecting sway bar lets the axle flex over uneven ground while locking the bar in for stable highway driving. The five-link coil rear works the same way, spreading wheel travel across rocky washouts instead of one wheel absorbing the full hit.

None of that geometry changes with engine choice. The 320 mm ground clearance, 24.6-degree approach angle, 25.5-degree departure angle, and 19.7-degree breakover angle carry over whether the truck leaves the lot with the HEMI or the Cummins under the hood. Engine choice shapes towing and daily driving, not how the truck clears a rock ledge.

Towing, Payload, and Jobsite Hauling

A 20,000 lbs (9,072 kg) max towing rating and 2,998 lbs (1,360 kg) of payload give the Power Wagon room for a loaded equipment trailer or a full bed of gear. The 1,829 mm cargo box and 117 L fuel tank support longer hauls without constant stops.

Frequent towing is the scenario that favours the Cummins. Its 1,075 lb-ft of torque arrives at low rpm, so a loaded trailer pulls away from a stop sign without the engine climbing through gears to find power. Drivers hauling near capacity most weekends will feel that difference over years of ownership.

Buyers who need secure jobsite storage can add the RamBox cargo management system, a lockable, weatherproofed bed storage option for the Power Wagon, along with heated power convex trailer tow mirrors with power-folding and memory functions.

Interior, Technology, and Everyday Comfort

Inside, the Power Wagon carries the same cabin quality found across the Ram Heavy Duty lineup. A heated cloth bench seat comes standard for a work-ready interior, with heated and ventilated leather-trimmed bucket seats available for a more finished feel. The Level 2 Equipment Group adds extended leather trim.

A Uconnect 5 touchscreen anchors the standard setup, with an upgrade available to a 14.5-inch Uconnect 5 display, a front-passenger interactive display, and dedicated trailer-tow and off-road information pages. An available 9-speaker Alpine premium audio system, or an upgraded Harman Kardon system, rounds out the options.

Standard tech and safety:

• Integrated trailer brake controller, rear backup camera with dynamic gridlines
• Front and rear park assist, adaptive cruise control
• Blind-spot monitoring with trailer coverage, pedestrian detection, rear cross-path detection

Which Power Wagon Engine Fits Your Drive?

If your weeks include hauling a trailer, be it equipment, a boat, or a camper, the Cummins turbo diesel is the build to spec. The low-end torque reduces strain on long tows and highway grades, and the fuel tank supports the extra distance those trips usually cover.

If your priority is technical trails, rock crawling, or a lighter truck for daily driving, the HEMI gas V8 is the more direct fit. It shares the same 4WD system, suspension, and trail geometry, so you are not giving up off-road hardware, only some low-end pull you may not use often.

Before you order, settle three things with the sales team: how often you will tow near the truck’s rated capacity, whether the Level 2 Equipment Group’s extended leather fits your use, and which touchscreen and audio setup suits your daily routine. Those choices lock in with the engine, not after it.

Speccing Your 2027 Ram Power Wagon

The 2027 Ram Power Wagon pairs its off-road hardware, 20,000 lbs (9,072 kg) towing rating, and 2,998 lbs (1,360 kg) payload with two distinct engines, so the right build comes down to how the truck will spend most of its time.

Visit Atlantic Dodge Chrysler Jeep in Halifax to sit in both engine setups, compare the standard and upgraded technology, and work with the sales team to spec the 2027 Power Wagon that matches your towing and trail plans.
