When it comes to diesel powered engines, one name stands well above anyone else—Cummins. The sophisticated 6.7L Cummins® Turbo Diesel powerplant continues its legacy of supplying pure, clean truck power. Unique Variable Geometry Turbocharging, means the turbocharger is side-mounted on this inline six-cylinder to simplify the design and help alleviate under-the-hood heat buildup that can occur with V8 engines.

Horsepower tops out at 350 providing ample acceleration, but it's the torque that really impresses, with best-in-class low-end torque^[1] that supplies an incredible 650 ft-lb^[2]. And this beast provides 16,500-lb of towing capacity without ever breaking a sweat.

The available 6.7-liter Cummins® Turbo Diesel engine provides tremendous power with ultra-clean emissions technology, making Dodge Ram 2500 and 3500 models the cleanest^[3] and strongest^[2] pickups ever.

With leading advances in diesel technology, Dodge has reduced the amount of harmful emissions from it's engines by 90-percent in the past decade. In fact, the Cummins® engine is the only diesel that meets EPA emission standards to date. The Dodge Ram 2500's closed-case system, means crankcase ventilation gases are rerouted for combustion, instead of released into the atmosphere.

In addition, the 6.7-liter Cummins® Turbo Diesel uses an oxidation catalyst in combination with managed engine combustion, increasing or decreasing exhaust temperature to mange a diesel particulate filter (DPF). This allows regeneration to take place under low-ambient/ low-load conditions when exhaust temperatures are low as well as during normal operation.

Whether its work or play, when it comes to capability in a full-size truck, the dominant 5.7-liter HEMI V8 engine gets the job done. With power that separates the men from the boys, this V8 churns out an impressive 330 horsepower and 375 lb-ft of torque boosting your capability above the rest.
