Performance

The Ram 2500 and 3500 are both available with either a gas or diesel engine. The gas engine will be a 6.4-liter HEMI V8, which gives you 405 horsepower and 429 lb-ft of torque. The Cummins diesel engine previously seen on the HDs has been redesigned. The high-output 6.7-liter Inline Six Cylinder Cummins Turbo Diesel engine will be available on both the 2500 and the 3500. You’ll see 430 horsepower and 1,075 lb-ft of torque. This is paired with an all-new 8-speed TorqueFlite transmission. The maximum towing capacity is a whopping 36,610 pounds.  

Design 

The Ram HDs will be available in Regular, Crew or Mega Cab configurations. The mega cab will have a 6’4” bed while the regular cab will have an 8” bed. With the crew cab, you have the option between the two. In terms of exterior redesign, the HDs took see many of the same updates that the light duties did. This includes bold redesigned grilles and front fascia that is specific to trim level. Also new are the updated headlights and taillights, which come standard as LED for all trim levels. You’ll see new wheel designs along with two new exterior colors.
