TFLtruck crew caught several Ram HD pickup trucks testing at high altitude at and able 9,000 ft of elevation. All of the test trucks had “Cummins Inc” stickers and ranged from 3500 duallies to 5500 HD chassis cabs. Some of the test truck were running empty, while others were hauling heavy goose-neck trailers like the one you see here.
Ford recently announced the power increase on their 2015 Power Stroke diesel up to 860 lb-ft of torque, and Cummins is not going to sit around. It’s not clear whether Cummins is working on improvements to the long time workhorse – the 6.7L straight-six motor, testing a new transmission combination, or trying out other engine configurations (such as a V8).
Let us know if you have more details you can share on the new Cummins and Ram developments.
