Major Milestone: Cummins Builds Two Millionth Ram Diesel Engine

By Trevor Dorchies | December 12, 2012
Cummins Engine Company, as it was known at the time, was founded back in 1919 with a straightforward plan to produce diesel engines for commercial use. Now, 93 years later, the Columbus, Ind.-based company is on the Fortune 500 list and turned a profit of $18 billion in 2011. As if Cummins hasn't enjoyed enough success, the engine builder, along with Ram trucks, celebrated the two millionth engine built for Chrysler's truck branch. This partnership between the two entities spans backwards over the course of four decades. Over the course of almost a century, Cummins has launched renowned diesel engines like the Model H in 1934 and would later provide coal burning mills for construction vehicles responsible for building this country's interstate highways. The engine company's latest milestone comes in the form of its two millionth engine built for Ram trucks, arguably one of the best business ventures either one has entered to date.
Chrysler and Cummins originally teamed up back in 1985 and began developing a 5.9-liter inline six-cylinder turbocharged diesel engine. That diesel engine wasn't launched until 1989 but when it did go on sale, it was rated at 160 horsepower and 400 pound-feet of torque. Today's Cummins diesel engine for Ram heavy-duty trucks produces more than double the power of its originator. The Cummins 6.7-liter high-output diesel engine is rated at 350 hp and an earth-moving 800 lb-ft of torque. The top-tier Cummins diesel engine for Ram produces 385 hp and an even stouter 850 lb-ft of torque. The Cummins engines that serve underneath the hood of the heavy-duty Rams on the road currently can be distinguished by its "Cummins Red" rocker cover and breather. Today's Ram pickups and chassis cab vehicles with active Cummins diesel engines are also distinguished by the engine company's "C" logo, as well.
As for the two millionth Cummins-built diesel engine for Ram, it's not going to see a single scrap of work as it will be put on display and tour the United States instead. As for those who will get to work, the 2013 Cummins-powered Rams include a 10 percent bump in fuel economy, a "smart" exhaust brake, a new cooling system, and only requires an oil change every 15,000 miles.  The 2013 Cummins diesel engine variant also is B20 compatible and features a next-generation Selective Catalytic Reduction and diesel exhaust fluid system that can go 4,000 miles between fill ups. According to Ram, around 80 percent of all heavy-duty customers take a Cummins engine home with them, too. Source: Ram
