For the new model year, Ram has doubled down on delivering power and capability, especially for customers who prioritize diesel performance. Let’s delve into the engine choices that will drive the 2025 Ram 2500 and what makes each option stand out.
Exploring the 2025 Ram 2500 Engine Lineup
Ram understands that heavy-duty truck buyers have diverse needs, and the 2025 Ram 2500 Engine Options reflect this understanding. The lineup features two formidable engines, each designed to offer a unique blend of power and reliability. Whether you’re prioritizing sheer torque for heavy towing or a balance of power and efficiency, the 2025 Ram 2500 has an engine to meet your demands.
Standard 6.4-liter HEMI V-8 Engine
For those who prefer a gasoline engine, the 2025 Ram 2500 continues to offer the tried-and-true 6.4-liter HEMI V-8 as the standard engine. This powerhouse delivers a robust 405 horsepower and 429 lb.-ft. of torque. The 6.4L HEMI is known for its responsiveness and strong performance in a variety of conditions, making it a capable choice for everyday tasks and demanding workloads alike. It’s paired with a TorqueFlite HD eight-speed automatic transmission, ensuring smooth power delivery and optimized performance. This engine is a solid foundation for the Ram 2500, providing ample power for most heavy-duty applications.
New 6.7-liter Cummins High-Output Turbo Diesel Engine
The headline engine for the 2025 Ram 2500 is undoubtedly the new 6.7-liter Cummins High-Output Turbo Diesel. Ram has listened to its customer base, with over 70% of Heavy Duty buyers opting for diesel, and significantly upgraded the Cummins offering. This new iteration of the inline-6-cylinder turbo diesel engine is a step up in terms of power and refinement. It boasts an impressive 430 horsepower and a staggering 1,075 lb.-ft. of torque. This substantial torque figure is particularly noteworthy, providing immense pulling power and making heavy towing feel effortless.
The improvements to the 6.7L Cummins are not just about raw power. Ram and Cummins engineers have worked closely to enhance several key areas, including:
- Drivability: The engine is designed to offer a more responsive and refined driving experience.
- Fuel Economy: Efficiency has been improved, especially when paired with the new eight-speed transmission and optimized axle ratios.
- Durability: Cummins engines are renowned for their longevity, and this new version builds on that reputation with redesigned components like a new block and head, and heavy-duty pistons.
- Startability: Enhanced cold-start performance is crucial for truck owners in colder climates, and glow plugs are utilized in Cummins High-Output Turbo Diesel equipped models.
- Serviceability: Features like top feed injectors and integrated fuel filters simplify maintenance.
- NVH (Noise, Vibration, and Harshness): Helical transmission gears and engine design improvements reduce noise and vibrations for a more comfortable ride.
These enhancements make the 6.7L Cummins High-Output Turbo Diesel not just more powerful, but also a more refined and user-friendly engine for the 2025 Ram 2500.
Performance and Capability Unleashed
The engine choices directly translate into the impressive performance and capability figures of the 2025 Ram 2500. Both engines are paired with the TorqueFlite HD eight-speed automatic transmission, but the overall performance characteristics differ significantly.
TorqueFlite HD Eight-Speed Transmission: A Key Partner
The TorqueFlite HD eight-speed automatic transmission is standard with both engine options and is a critical component in maximizing performance and efficiency. Its wide gear ratios allow for optimized engine rpm across various driving conditions. Notably, the transmission is designed to enable smooth second-gear starts when the truck is unladen, improving refinement in everyday driving. For heavy loads and towing, the transmission ensures that the engine operates in its optimal power band, delivering confident performance.
Towing and Payload Capacity: Leading the Pack
When it comes to work, the 2025 Ram 2500 engine options deliver exceptional towing and payload capabilities. The maximum towing capacity for the 2025 Ram 2500, when equipped with the 6.7-liter Cummins High-Output Turbo Diesel, reaches an impressive 36,610 pounds (16,606 kilograms). This capability is achieved with a more fuel-efficient 3.42 rear axle ratio, which is a significant improvement as previously, maximum towing required a 4.10 axle ratio.
The 6.4-liter HEMI V-8 also offers substantial capability, with a maximum payload of 7,590 pounds (3,443 kilograms). These figures position the 2025 Ram 2500 as a leader in its class for both towing and hauling.
Acceleration Improvements: Quicker off the Line
The enhanced power of the new Cummins High-Output Turbo Diesel also translates to improved acceleration. The 2025 Ram 2500 with this engine achieves a 0 to 96 km/h (0-60 mph) time of 6.9 seconds, a noticeable improvement compared to the 8.0 seconds of the previous model year. This quicker acceleration makes the truck feel more responsive and agile, both in everyday driving and when merging onto highways with a load.
Advanced Technology and Driver-Centric Features
Beyond the engine bay, the 2025 Ram 2500 is packed with technology that enhances the driving experience and simplifies demanding tasks. The Uconnect 5 system, available with a 12-inch or new 14.5-inch touchscreen, provides intuitive access to vehicle controls and connected services. Features like Trailer Reverse Steering Control, Trailer-Tow Pages, and available digital rearview mirror with tow mode, are designed to make towing safer and easier. Furthermore, the available on-board power inverter adds practicality for job sites or outdoor activities, providing up to 2.4 kilowatts of power directly from the truck bed.
Conclusion: Power and Choice in the 2025 Ram 2500
The 2025 Ram 2500 engine options deliver on the promise of power, capability, and refinement. Whether you choose the standard 6.4-liter HEMI V-8 or opt for the upgraded 6.7-liter Cummins High-Output Turbo Diesel, you’re getting a robust engine designed to handle the toughest tasks. Ram’s commitment to powertrain leadership is evident in the improvements made to the Cummins diesel, offering truck buyers a compelling reason to choose the 2025 Ram 2500 for their heavy-duty needs. With these engine choices and a host of advanced features, the 2025 Ram 2500 is set to continue Ram’s legacy of building benchmark-quality trucks.
