Class-dominating Cummins Power
The 5.9-liter Cummins Turbo Diesel is the king of the heavy-duty diesel segment with class-dominating 610 lb.-ft. of torque at 1,600 rpm – peaking earlier than either Ford’s PowerStroke or Chevrolet’s Duramax® diesels – translating to a noticeably better vehicle launch when towing and accelerating, as well as better drivability.
 
“The Cummins Turbo Diesel is the engine of choice for 85 percent of Dodge Ram Heavy Duty customers,” said Donoughe.  “Unlike other diesel options on the market, Cummins is synonymous with smooth power delivery, best-in-class torque, excellent fuel economy and durability that is unmatched in the industry.”
 
The Cummins Turbo Diesel offers reliability, durability and efficiency with an in-cylinder combustion and a diesel oxidation catalyst solution that requires no exhaust gas recirculation components.  In addition, gallery-cooled, high-strength aluminum pistons provide increased durability, resulting in an average of 350,000 miles before overhaul.
