The heavy-duty truck segment boasts some of the tightest competition of any automotive niche in the US. Being able to tout just one best-in-class figure can be a marketing advantage over competitors, and Ram Trucks is adding one more accolade to its tally with a powertrain update for the 2015 Ram 2500 and 3500 Heavy Duty pickups. Ram now claims best-in-class ratings for torque, towing and payload, depending on configuration.

The major change comes for the 3500 HD with a boost in torque for its Cummins 6.7-liter, inline-six diesel engine. It now produces a meaty 865 pound-feet of twist, a boost of 15 lb-ft, which is the best figure in its segment, according to the company. To eek out the extra power, the mill has more aggressive fuel delivery, and the turbo has been recalibrated. Of course, more grunt would be meaningless if drivers couldn't do anything with it, and the tweaks help allow payload to grow to 7,390 pounds, up from a rating of 7,320 pounds last year. The max towing rating remains unchanged at 30,000 pounds, though.

The rest of the powertrain lineup carries over from last year. The base HD mill is the gasoline-fed 5.7-liter V8 with 383 hp and 400 lb-ft and a six-speed automatic. The next step up is a 6.4-liter V8 with 410 hp and 429 lb-ft. There are also three trims of the 6.7-liter Cummins diesel starting with 350 hp and 660 lb-ft with a six-speed manual gearbox. If buyers opt for a the 68RFE six-speed auto, they get 370 hp and 800 lb-ft. Finally, there's the updated, top-rung version with 385 hp and 865 lb-ft with an Aisin six-speed automatic transmission.

These brawny new pickups begin rolling off the line at the Saltillo Truck Assembly Plant in Coahuila, Mexico, this week. Scroll down for the official announcement along with a video of Mike Cairns, director of engineering at Ram Truck, talking about the best-in-class specs.Continue reading Ram boosts Heavy Duty truck claims for 2015 [w/video]

Thats cool, but i'd want them to put the truck on a load dyno to prove it has the torque they say.
