Fuel Economy and Real-World MPGįuel economy is not estimated by the EPA on commercial vehicles such as the Ram 25 because their Gross Vehicle Weight Ratings (GVWR) are more than 8500 pounds. With the standard V-8, the truck can also handle 3240 pounds, and tow 14,370, which is more than enough for most jobs and weekend expeditions. With the 370-hp version of the Cummins, the 2500 4x4 Crew Cab can haul 3240 pounds and pull 16,870.

When equipped with that engine, the more popular 2500 4x4 Crew Cab model offers a max payload of 2380 pounds and a max trailer-weight rating of 19,010 pounds. With the high-output Cummins and its 1075 pound-feet of torque, a Ram 3500 has a towing capacity of 37,090 pounds and a maximum payload of 7680 pounds.

Although it's still noisier than the V-8, it's no longer a raucous beast. Ram has done an incredible job refining the Cummins. 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. Both engines are backed by a six-speed automatic, whereas its diesel competitors all pack more modern 10-speed transmissions. The 400-hp high-output version, only available on the 3500, makes an incredible 1075 pound-feet of torque. The first is available in both 25 models and makes 370 horsepower and 850 pound-feet of torque. Two versions of the diesel are available. However, every other model is also offered with a 6.7-liter Cummins diesel inline-six with either rear- or four-wheel drive. This is the only engine and transmission offered in the Power Wagon, which is exclusively four-wheel drive. It's paired with an excellent eight-speed automatic. Standard power in all models comes from a 410-hp 6.4-liter V-8, which makes 429 pound-feet of torque. With the dollars saved, spring for the limited-slip differential and load-leveling air suspension, which further improves the Ram's already impressive ride quality. Although more are sold with the Cummins, stick with the 410-hp V-8, which is quicker around town and pairs with an excellent eight-speed automatic, unless towing huge trailers is a high priority for you. For the best mix of capability, space, luxury, and price, we would stick with the most popular model, the 2500 4x4 Crew Cab Laramie. Most Ram HD buyers are willing to pay up for the diesel, but the standard 410-hp 6.4-liter gas engine is plenty capable, even in the 3500.
