Durability, quality and reliability lead the impressive list of Ram assets. It's what makes Ram the longest lasting,^[1] most durable^[2] family of full-size pickups. Multiple systems on all Ram trucks are subject to the most punishing environments and terrain on the planet before they get to your driveway.

We put a single Ram through grueling trials that range from 120°F deserts to -20°F arctic climates. Name the challenge: towing in the mountains, running for a week without stopping. For reliability and durability that carries the day, look to Ram. It's been tested.

When it comes to diesel powered engines, one name stands well above anyone else—Cummins. The sophisticated 6.7-liter 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^[3] that supplies an incredible 650 ft-lb^[4]. 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^[5] and strongest^[4] 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.
