Cummins Inc. produced its 3-millionth diesel engine for Ram trucks at its Columbus Mid-Range Engine Plant (CMEP) in Indiana, highlighting the latest milestone in a partnership that spans more than three decades, according to the engine maker.

“The relationship that Ram Truck has with Cummins is one of the industry’s most enduring, and continues to raise the bar for power and durability,” said Reid Bigland, Head of Ram Brand. “Both companies have benefitted from this partnership, but Ram customers truly get to enjoy the toughness and best-in-class capability that a Cummins-powered Ram Heavy Duty truck delivers.” 

The new 400-hp, 6.7L inline six-cylinder turbodiesel high-output engine is the first engine to break the four-figure torque barrier, according to Ram. Additionally, the new engine boasts a host of upgrades including new block, pistons, cylinder head, and valvetrain, for more power, better fuel efficiency and reduced noise, vibration, and harshness (NVH).

According to Cummins the milestone adds to a legendary history that includes:

• 1988: Introduced first Cummins-powered Ram for model-year 1989.

• 1996: Exceeded 200 horsepower.

• 2001: Surpassed 500 lb.-ft. of torque.

• 2007: Launched 6.7L, 350-horsepower engine.

• 2013: Reached 385 horsepower, 850 lb.-ft. of torque.

Ram Truck and Cummins are celebrating this newest milestone with a group of 20 Cummins employees who have been working on Ram Truck - Cummins engines since the inception of the companies’ partnership.

"We are grateful to Ram Truck for choosing Cummins-powered engines for 30-plus years, and we look forward to a long partnership,” said Melina Kennedy, Executive Director of Cummins Pickup Business. “We are honored that these 20 employees have chosen to devote the 30-plus years to Cummins. They and the whole plant team are a big-hearted group committed to improving where they live.”
