New Lineup of Heavy Duty Ram Trucks Offer Performance and Versatility
Fleet operators need a combination of reliability, capability, and efficiency from their Heavy Duty work trucks. The 2025 Ram 2500 and 3500 models are designed for fleet use — offering a blend of power, safety, and smart connectivity that sets a new benchmark in the market.
Enhanced Powertrain and Capability
Performance is non-negotiable for commercial fleet owners. Stellantis has made a decisive move by standardizing its most powerful diesel engine across its Heavy Duty Ram truck lineup. “We’re now bringing in our most powerful variant of the diesel from an output perspective, making it standard across our lineup,” said David Sowers, director of commercial operations at Stellantis. “Fleet customers are always looking for more capability, especially when it comes to towing. With this powertrain upgrade, we’re delivering better performance, efficiency, and total cost of ownership — which are critical for commercial operators.”
The 2025 Ram Heavy Duty lineup introduces a new 6.7-liter Cummins High-Output Turbo Diesel engine, producing 430 horsepower and a best-in-class 1,075 lb.-ft. of torque. For fleets that prefer a gasoline option, the 6.4-liter HEMI V-8 delivers 405 horsepower and 429 lb.-ft. of torque.
These powertrains, paired with the upgraded 8-speed TorqueFlite HD transmission, eliminate the need for multiple axle ratios and optimize towing capabilities, offering up to 37,090 lbs of towing capacity and a payload of 7,590 lbs. The unified axle ratio simplifies operations for drivers, reducing maintenance costs and enhancing performance predictability.
The TorqueFlite HD transmission also facilitates adaptive shifting, enabling Ram trucks to adjust gear speeds dynamically based on load and terrain. “It starts in second gear when it is unloaded and tow/haul mode is not engaged, offering smoother shifting and improved efficiency,” noted Sowers.
Customer-Centric Design
Fleet managers increasingly expect trucks with the same safety and convenience features found in passenger vehicles. “More and more, fleet customers are demanding the same level of safety features on their trucks that they get on their passenger vehicles,” Sowers said. “Features like adaptive cruise control and forward collision warning help them avoid accidents, reduce downtime, and lower liability costs — key concerns for any fleet operator.”
Stellantis has responded to fleet owner needs by making advanced safety and driver-assist technologies standard across the Ram work truck lineup. The trucks now include adaptive cruise control, emergency braking, and forward collision warning — mitigating potential accidents and reducing insurance and maintenance costs. The addition of LED headlights also enhances nighttime visibility and driver safety.
Driver usability remains a focal point, with an ergonomic column shifter designed for quick, seamless gear changes across both gas and diesel configurations. A 360-degree surround-view camera with trailer reverse guidance simplifies maneuvering for fleet operators who rely on towing. “A safer and more user-friendly truck ultimately leads to reduced training time, fewer operational delays, and improved driver satisfaction,” Sowers said.
The 2025 Ram trucks also cater to driver comfort and connectivity with a 12-inch digital cluster and infotainment system with Apple CarPlay and Android Auto integration. These features align commercial vehicles with personal cars, enabling operators to use their trucks for both work and personal applications.
Versatile Fleet Applications
Fleet operators need versatility, whether they manage government vehicles, utility company fleets, or worksite trucks. The Ram Heavy Duty lineup offers an array of factory-installed options designed to accommodate specialized fleet applications.
“For our commercial customers in the marketplace, they are always looking for capability, usability, and efficiency in their platforms,” Sowers said. “The main reason for customers to move from a light-duty truck to a Heavy Duty truck is that they’re towing something, and they’re towing it often. So they’re looking for usability and safety while towing. We deliver that in spades with this truck.”
The Ram lineup includes configurations ranging from standard work trucks to off-road packages like the Ram Rebel and Power Wagon. These models come equipped with off-road enhancements such as locking axles, 35-inch tires, and ultra-low-range transfer cases for tackling rough terrain. A relocated digital rearview mirror improves visibility, while a live-drive PTO system allows the trucks to power external equipment, such as snow removal and dump truck operations.
“The Power Wagon is particularly noteworthy, featuring front and rear axles, a disconnecting front sway bar, and an optional 12,000-pound winch for ultimate utility in rugged environments,” Sowers explained.
Technological Integration for Fleet Optimization
In today’s data-driven world, telematics and connected vehicle technology have become indispensable tools for fleet management. Ram has embraced this shift, offering standard connectivity features across all 2025 models.
“Connected vehicles are a must-have now for fleet managers,” Sowers said. “Telematics provides the ability to track vehicles, monitor how they’re being operated, and predict required maintenance intervals. By offering these tools as standard, we’re helping fleets optimize usage, improve safety, and lower costs.”
Thanks to a partnership with Free2Move, a mobility solution provider, Ram trucks can benefit from fleet tracking and operational oversight — providing real-time vehicle data and predictive maintenance alerts. Fleet managers can choose between raw data integration for advanced analytics or a user-friendly dashboard that simplifies decision-making.
Real-time data also supports predictive maintenance, enabling fleet operators to proactively address mechanical issues – reducing unplanned downtime and extending vehicle lifespans. Predictive maintenance improves operational efficiency and lowers the total cost of ownership.
A New Standard in Heavy Duty Trucks
As competition in the Heavy Duty truck segment intensifies, manufacturers must differentiate through performance, reliability, and technological innovation. Stellantis has positioned itself at the forefront of this transformation with its latest Heavy Duty truck models.
“The combination of powertrain upgrades, advanced safety features, and connectivity tools reflects what the market demands—more capability, reliability, and efficiency,” Sowers said. “Fleet customers want vehicles that not only perform but also reduce downtime, lower operational costs, and provide a better experience for drivers. The Ram Heavy Duty lineup delivers on all fronts.”
By addressing key fleet concerns—power, safety, usability, and technology—Ram’s 2025 Heavy Duty trucks reinforce their reputation as the workhorses of the marketplace, ensuring that fleet operators can meet everyday challenges with confidence.
