The Ram 2500 offers bold styling with an aggressive "grille-forward" design, interiors with premium materials and innovative features, and big power from a choice of engines, making it ideal for work and play. Four revised grille designs and a premium headlamp lighting system with a bi-functional halogen projector design and amber turn-signal LEDs are available. For 2013, new features and technologies create opportunity for a redesigned interior with material upgrades, improved fit and finish, all-new interior themes with different colors and materials, and new multimedia systems.

The standard trailer hitch is upgraded to Class 5. Heated and ventilated front seats, heated rear seats, heated steering wheel, power adjustable pedals, Keyless Go passive entry, rear parking sensors, and a rear backup camera are available.
