The 2025 Ram 2500 Heavy Duty: A Deep Dive into the Diesel Powerhouse
The 2025 Ram 2500 Heavy Duty represents a significant update to Ram’s popular heavy-duty pickup truck. While the exterior styling receives a refresh, as seen in early teaser images and discussed on sites like www.stellpower.com, the most substantial changes lie beneath the surface, focusing on the powertrain and drivetrain. Rumors and reports from various sources, including Diesel Army (www.dieselarmy.com) and Mopar Insiders (moparinsiders.com), paint a picture of a significantly improved truck. Let’s delve into the details.
Powertrain Enhancements: A New Era for the Cummins Engine
The heart of the 2025 Ram 2500 Heavy Duty remains the legendary Cummins 6.7-liter inline-six-cylinder turbodiesel engine. However, this isn’t simply a carryover. Reports suggest a return to a gray iron engine block from the compacted graphite iron (CGI) block used in previous iterations. This change, as highlighted on www.dieselarmy.com, aims to improve noise, vibration, and harmonics (NVH), leading to a quieter and smoother driving experience.
Further improvements include a completely redesigned cylinder head. This new head eliminates the problematic grid heater system in favor of glow plugs. This modification promises better cold-start performance and increased reliability, addressing a common point of failure in previous models. The new design also features external fuel injectors and lines, simplifying maintenance and servicing.
A new Holset turbocharger is another key addition. While the displacement remains at 6.7 liters, power output is expected to increase to a considerable 430 hp and 1075 lb-ft of torque. This represents a substantial improvement over the previous high-output (H/O) version, effectively making the high-output power available in the 2500 model for the first time.
Transmission Transformation: The ZF 8-Speed Automatic
The 2025 Ram 2500 HD’s powertrain upgrade extends beyond the engine. The aging six-speed automatic transmission is finally being replaced by a ZF 8-speed automatic transmission, specifically the 8AT Powerline model. This robust transmission, already proven in medium-duty trucks and buses, is expected to significantly improve reliability, acceleration, and fuel efficiency. Discussion on www.stellpower.com suggests a potential 10% increase in fuel economy. The new transmission’s twin power takeoff (PTO) units also open up possibilities for future hybridization.
