Ram (Auburn Hills, Michigan) unveiled the new 2025 Ram Heavy Duty trucks, featuring a new 6.7-liter Cummins High-Output Turbo Diesel engine. Ram’s latest heavy haulers relentlessly give maximum effort with a unique combination of exceptional comfort, innovation, technology and capability.
“More than 70 percent of Ram Heavy Duty customers opt for the diesel, and for 2025 we built on that demand and long-lasting durability with an improved Cummins engine coupled with a new eight speed transmission,” said Tim Kuniskis. “This is a very specific pickup segment that requires a powerful tool — every 2025 Ram 2500 we sell allows the potential of 1075 lb.-ft. of torque in every gear, for a 70 percent increase in torque delivery from the previous generation 2500.”
Ram 2500 and 3500 Heavy Duty Powertrain
The 2025 Ram 2500 and 3500 Heavy Duty offers customers two engine options — the new 6.7-liter Cummins High-Output Turbo Diesel engine and the standard 6.4-liter HEMI® V-8 engine. The new Cummins Turbo Diesel engine and TorqueFlite HD eight-speed transmission upgrades enable 36,610 pounds of towing capability with a more fuel-efficient 3.42 rear axle ratio. Max towing was previously available only with a 4.10 axle ratio.
The 2025 Ram 2500 now offers the Cummins High-Output Turbo Diesel engine, which results in quicker 0 to 60 mph times (6.9 seconds vs 8.0 seconds on 2024 MY).
A new electronic column shifter and TorqueFlite HD eight-speed automatic transmission are standard equipment on both engines. The Ram Heavy Duty engine control system recognizes if the truck is loaded or unloaded and the new TorqueFlite transmission allows for smooth second-gear starts when unladen.
The all-new 6.7-liter Cummins High-Output Turbo Diesel is rated at 430 horsepower and 1,075 lb.-ft. of torque, while the 6.4-liter HEMI V-8 is rated at 405 horsepower and 429 lb.-ft. of torque. Capability includes a maximum towing capacity of 36,610 pounds (diesel) and a maximum payload of 7,590 pounds (gas). Ram 3500 Heavy Duty maximum gooseneck and conventional hitch maximum trailer weight ratings for 2025 are 36,610 pounds and 23,000 pounds, respectively.
For 2025, the Ram Heavy Duty lineup includes Tradesman, Big Horn/Lone Star, Laramie, Rebel, Power Wagon, Limited Longhorn and Limited models.
The entire Ram lineup will offer customers benchmark gas, turbo diesel and electric vehicles that get the hard work done and families where they need to go. Ram is committed to innovation and powertrain leadership with a lineup that consists of anything and everything truck buyers want and need.
The new 2025 Ram Heavy Duty is part of Ram’s significant contribution to Stellantis’ Dare Forward 2030 strategic plan to lead the way the world moves by delivering innovative, clean, safe and affordable mobility solutions. Reducing greenhouse gas emissions is a key element of the Stellantis Dare Forward 2030 strategic plan. Stellantis is committed to cut its carbon footprint by 50 percent by 2030, all while achieving net carbon zero by 2038.
The new 2025 Ram 2500 and 3500 Heavy Duty is scheduled to arrive in dealerships in the first quarter of 2025.
Heavy Hauler Capabilities Elevated With New Cummins Turbo Diesel Power Option
Working closely with Cummins, the 6.7-liter High-Output inline-6-cylinder Turbo Diesel engine boasts several improvements in drivability, fuel economy, durability, startability, serviceability and noise, vibration and harshness (NVH).
A redesigned block and head, robust heavy-duty pistons, new performance intake manifold, a new turbo, larger intake/exhaust valves for improved port flow and a higher-pressure fuel system enhance the diesel’s hallmark durability and efficiency.
To make service easier, and improve air flow and performance, the new Cummins engine uses improved intake port geometry for top feed injectors, top load lubrication and integrated fuel filters. Helping customers in extremely cold environments, Ram Heavy Duty trucks equipped with the Cummins High-Output Turbo Diesel use glow plugs. Noise, vibration and harshness were reduced using helical transmission gears.
The new 2025 Ram 2500 and 3500 Heavy Duty integrates the TorqueFlite HD eight-speed automatic transmission that features a lower cruise engine rpm and improved performance on graded roads. Wide gear ratios allow for a reduction in rear axle ratio without compromising capability. The TorqueFlite HD eight-speed automatic transmission and new electronic column shifter are now standard on both engine options.
Face of Durability and Reliability Telegraphs An Unmistakably Bold, Heroic Presence
For 2025, Ram Heavy Duty pickups feature updated grilles with a unique design, depending on the selected trim level. New premium LED headlamps, including twin bi-functional projectors, are available, while LEDs are now standard.
The best lockable bed storage in the segment continues to be available with RamBox, featuring a 115-volt outlet. The class-exclusive RamBox cargo management system includes versatile, weatherproof, lockable, illuminated and drainable storage bins built into the bed rails. Available with RamBox is a pickup bed divider and cargo rail system with four sliding, adjustable cleats.
Other exterior design updates include new wheels catering to a wide variety of buyers and available in unique interpretations as dictated by the model. New incandescent taillamps are standard while a premium version with LEDs with Blind-spot Monitoring is available on select models.
Hard Work Simplified With Advanced Technology, Comfort And Innovative Features
The new 2025 Ram 2500 and 3500 Heavy Duty feature the latest, most advanced Uconnect system ever, with an improved 12-inch or new 14.5-inch touchscreen display and intuitive user experience.
The Uconnect 5 system offers even more connected services and features for unmatched ease of use.
Highlights of the system include:
- Improved 12-inch touchscreen with higher resolution and new 14.5-inch reconfigurable touchscreen displays that feature split-screen capability for dual application operation. Both touchscreens use Full Array Local Dimming technology, enabling a higher contrast ratio than a conventional edge-lit screen
- New segment-first 10.25-inch passenger screen with three major functions: co-pilot (navigation, device management), entertainment (via HDMI) and the ability to view the exterior vehicle cameras. Visible only to the front passenger and with dynamic touchscreen control, it offers an HDMI plug that lets occupants connect their phone or tablet, turning the touchscreen into a mirrored extension of their device that allows internet searches, music and app use to project through the Uconnect 5 system. The 2025 Ram Heavy Duty is the only heavy duty truck to offer this feature
- Advanced Atlantis electrical architecture enhances Uconnect 5 with operating speeds that are five times faster than the previous generation architecture and offers more memory and lightning-quick response to touchscreen input in as little as .05 seconds
Other new innovative features include:
- An on-board power inverter offers up to 2.4 kilowatts with two covered outlets located inside the bed of the Ram 2500 and 3500 Heavy Duty. With the engine running and while the truck is parked, customers can turn the inverter on via the touchscreen and with a switch located to the left of the outlets. The engine will then ramp up revolutions per minute (rpm) to support the on-board power inverter.
- Available class-exclusive dual wireless phone charging enhances functionality for front passengers and connectivity ports that are sculpted for quick recognition.
- Enhanced Lane Keep Assist leverages blind spot sensors to provide additional steering corrections for lane centering.
- An available fully digital rearview mirror with tow mode provides an unobstructed rear view that enhances safety and visibility. The digital rearview mirror displays video in real time from a rear-facing camera, offering an image that is unobstructed by the D-pillars or rear seats. It also reverts to a traditional reflective mirror by toggling the switch underneath.
- Power telescoping trailer tow mirrors allow the driver to move the mirrors away from the truck to enhance sightlines while towing.
- Trailer reverse steering control, located below the touchscreen, allows the driver to enter a few measurements before the camera tracks the trailer position and the driver is backing up and guiding the trailer. The driver simply rotates the dial left or right in the direction they want the trailer to go while the system controls the steering wheel. Trailer-Tow Pages gives customers the ability to view comprehensive trailer monitoring information including Trailer Light Check-out, available trailer tire pressure monitoring, Trailer Brake Status and auxiliary camera shortcuts, all in one application accessible through the Uconnect touchscreen.
- A 12.3-inch digital gauge cluster shows nearly two dozen different menus, including driver-assist technologies such as adaptive cruise control, active driving assist, Drowsy Driver Detection and Traffic Sign Information.
- New standard safety features include adaptive cruise control, Forward Collision Warning-Plus, ParkSense front/rear park assist (Big Horn). New Drowsy Driver Detection, Traffic Sign Recognition and Active Lane Management are available.
