2015 Ram 2500/3500 HD
Ram Trucks has introduced a revised, High Output 6.7L Cummins turbodiesel for the 2015 model year, peaking at 865 lb-ft. The H.O. model is available for the Ram 3500, while the 2500 model retains the 370 horsepower, 800 lb-ft version of the Cummins. The standard engine is backed by Chrysler's 68RFE, while the H.O. transmits power via the medium duty Aisin six speed automatic. The G56 manual transmission remains optional, but comes with engine output detuned to 660 lb-ft; Ram remains the only manufacturer to offer a manual gear box. Furthermore, all of Ram's pickups now feature SAE J2807 certified tow ratings.

2015 Chevy SIlverado, GMC Sierra 2500/3500 HD
The GMC Sierra and Chevrolet Silverado HD models remain relatively unchanged for the 2015 model year, still offering the 397 horsepower, 765 lb-ft Duramax diesel matched with the Allison 1000 transmission. The 3500 model offers the highest in-class bumper pull tow rating with an astonishing 19,600 lbs. The GMC Sierra receives a new trim package, the All Terrain HD, which finishes the truck off with a number of aesthetic upgrades and plenty of creature comforts. GM's HD models have yet to utilize SAE J2807 criteria in determining their maximum tow ratings, but are expected to adopt the new standards upon the platforms next major redesign.

2015 Ford Super Duty
The workhorse of Ford's Super Duty lineup, the F-450, is revamped for the 2015 model year to deliver increased tow ratings, which have been determined under the SAE's J2807 criteria. Neither the F-250 nor F-350 use the SAE standard, but are expected to do so in the next major platform upgrade. The 6.7L Power Stroke has also been revised, increasing performance by 40 horsepower and 60 lb-ft of torque. The twin sequential turbocharger has been replaced with a more efficient, larger single turbo, which contributes to the engine's power increase. The Power Stroke comes standard with Ford's TorqShift six speed automatic transmission.
