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

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.

Cummins unveiled a new 2025 6.7-liter Turbo Diesel Pickup engine system for Ram Heavy Duty, along with its partners at Ram, on Wednesday.

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.

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