The Model Year (MY) 2018 Cummins 6.7L Turbo Diesel engine is a featured option for 2018 RAM 2500 and 3500 pickups and RAM 3500, 4500, and 5500 chassis cabs. This dynamic inline 6-cylinder gives RAM class-leading power and towing capacity, producing up to 385 horsepower and 930 pound-feet torque.

Features & Benefits

The MY 2013.5+ Cummins 6.7L Turbo Diesel reduces operating costs in today’s RAM trucks with a new Selective Catalytic Reduction (SCR) aftertreatment that uses Diesel Exhaust Fluid (DEF), contributing to a 10 percent increase in fuel economy and best-in-class 15,000-mile oil-change intervals, keeping more of your hard-earned money in your pocket.

Owners also benefit from a new cooling system that affords 25 percent more heat-rejection capacity. A high-efficiency fan, dual radiators, dual transmission coolers and a charge-air cooler lower operating temperatures and deliver improved performance.

Also improved is the biofuel capability. The MY 2013.5+ engine is B20-capable, adding flexibility at the pump. You have the option to use ultra-low- sulfur diesel or up to B20 biodiesel, where available.

Another feature is the “smart” exhaust brake. The VGT™ Variable Geometry Turbo is enhanced through the addition of a brake feature that electronically controls the exhaust braking to maintain a set vehicle speed while descending a grade.
