Ram 2500 and Ram 3500 will both be getting a new version of the Cummins turbodiesel engine that pumps out 800 lb-ft of torque, according to Ram CEO Fred Diaz.  The maximum towing capacity of the Ram is now 22,700 lb, besting Ford and GM, with a best in class maximum gross combined weight rating of 30,000 pounds. Peak horsepower remains the same (350 hp at 3,000 rpm) but thanks to other changes, an additional 40 hp is available in the normal cruising range.

The 800 lb-ft engines also have a new crankshaft damper to reduce noise and vibration; trucks so equipped will get a “high output Cummins” badge on the tailgate.

Diaz also said that the Ram had the largest brakes in its class, the most powerful exhaust brake in its class, and the only engine that does not use urea or any other emissions-reducing fluid.

The extra power is handled by a new, higher-rated torque converter which is better integrated for higher towing capability. In addition, a new dual-rear wheel axle with 4.10 gear ratio, new rear-axle pinion, new helical gears, upgraded bearings, and finned aluminum differential cover are used with the maximum towing package; a new engine-mounted oil-to-coolant transmission cooler and upgraded power steering oil coolers will also be used.

The high tow ratings meet all 2013 model-year SAE standards.
