Ram heavy-duty truck lineup unveiling also served as the first phase of a comeback tour for former CEO Tim Kuniskis.

Ram unveiled official specifications for its updated 2025 heavy duty trucks Tuesday, making strides in arguably the biggest pissing contest of the automotive space. For 2025, Ram’s HD trucks bring bolder looks that were teased last year,

The 430-horsepower Cummins Turbo Diesel delivers a 70% rise in torque. The diesel option is offered on Ram 2500 and 3500 HD and 3500, 4500, 5500 Chassis.

Stellantis has redesigned its large Ram heavy-duty trucks, which are expected to arrive at dealers in the first quarter of this year and will start at $47,560.

As in previous years, Ram offers the 2025 Heavy Duty in three cab configurations (regular, extended, and crew) and two cargo bed lengths. Trim levels include Tradesman, Big Horn, Lone Star (available only in Texas), Power Wagon, Rebel, Laramie, Limited Longhorn, and Limited.

The Ram brand of Stellantis in Auburn Hills has unveiled its new 2025 fleet of heavy-duty trucks, which it says offers a “combination of exceptional comfort, innovation, technology and capability.”

Ram's heavy-duty pickups will continue to offer V8 power in the US, but the real news is an overhauled turbo-diesel inline six.

Ram 2500 and 3500 Heavy Duty are hitting dealerships soon, and Ram kept one of their most essential features alive and even more powerful.
