While urban automobiles compete mostly in emotional aspects, such as design or performance, pick-up trucks take their affairs to numbers. The midsize model of RAM’s heavy-duty lineup now features both the highest payload and the highest towing rates: impressive 7,390 lb using the 6.4-liter Hemi V8, and breathtaking 31,210 lb with the 6.7-liter Cummins diesel. These figures were reached by reinforcing the rear axle, strenghtening the differential’s case, and tweaking the latter engine: recalibrated fuel delivery and turbo boost added 35 lb-ft, taking its torque to another superlative number: 900 lb-ft.
