Engine, Transmission, and Performance
Three engines are available. Standard power in all models comes from a 410-hp 6.4-liter V-8, which makes 429 lb-ft of torque. It's paired with an excellent eight-speed automatic. This is the only engine and transmission offered in the Power Wagon, which is exclusively four-wheel drive. However, every other model is also offered with a 6.7-liter Cummins diesel inline-six with either rear- or four-wheel drive. Two versions of the diesel are available. The first is available in both 2500 and 3500 models and makes 370 horsepower and 850 lb-ft of torque. The 400-hp high-output version, which is only available on the 3500, makes an incredible 1075 lb-ft of torque. Both engines are backed by a six-speed automatic whereas its diesel competitors all pack more modern 10-speed transmissions. At 1060 pounds, the Cummins engine outweighs the V-8 by 490 pounds, so the diesel models don't handle quite as well around town, and they're not quick, but they can haul and tow significantly more weight. Ram has done an incredible job refining the Cummins. Although it's still noisier than the V-8, it's no longer a raucous beast.
