2025 Ram Heavy Duty Introduces Enhanced Cummins Engine with Class-Leading Torque

Ram has unveiled substantial powertrain updates for its 2025 Heavy Duty lineup, headlined by a new 6.7-litre Cummins High-Output Turbo Diesel engine. This enhanced powertrain delivers 430 horsepower and class-leading standard torque of 1,075 lb-ft, marking a substantial improvement over its predecessor. The latest generation of Ram Heavy Duty trucks combines this powerful engine option with a new TorqueFlite HD eight-speed transmission, enabling superior towing capabilities and improved performance metrics.

The 2025 model year brings notable improvements in acceleration and overall capability. The Ram 2500 now achieves 0 to 96 km/h in just 6.9 seconds, significantly quicker than the previous model's 8.0-second time. These enhancements prove Ram's promise to deliver both power and efficiency in its heavy-duty truck lineup.

Advanced Engineering Meets Practical Performance

The reimagined 6.7-litre Cummins High-Output Turbo Diesel represents a comprehensive upgrade to Ram's powertrain offerings. Engineers have implemented several crucial improvements, including a redesigned block and head, robust heavy-duty pistons, and a new performance intake manifold. The engine also features a higher-pressure fuel system and larger intake/exhaust valves, enhancing both durability and efficiency. These modifications not only boost performance but also improve fuel economy and reduce noise, vibration, and harshness levels.

Working in concert with the new engine, the TorqueFlite HD eight-speed automatic transmission enables a maximum towing capacity of 16,606 kilograms with a more efficient 3.42 rear axle ratio. This combination delivers optimal performance across various driving conditions, whether hauling heavy loads or navigating city streets.

Technology Integration Enhances Capability

The 2025 Ram Heavy Duty introduces advanced technology features that complement its enhanced powertrain. The latest Uconnect 5 system comes with an available 14.5-inch touchscreen display, offering intuitive control over vehicle functions and entertainment options. For towing applications, the new lineup includes innovative features such as trailer reverse steering control and comprehensive trailer monitoring through the Trailer-Tow Pages system.

Safety technology has also been upgraded, with new standard features including adaptive cruise control and Forward Collision Warning-Plus on Big Horn models and above. The available 360-degree surround-view camera system with trailer reverse guidance provides enhanced visibility and control while manoeuvring with a trailer.
