In 2014, Ram added a new engine option to its lineup of light-duty, Ram 1500 pickup trucks. The EcoDiesel engine claimed to deliver better mileage than competing gasoline engines, a quieter ride than traditional diesels, and enough towing prowess. From 2014, until the discontinuation of the EcoDiesel engine in 2023, these two engines were the only diesel powerplant options for Ram pickup trucks. The Cummins 6.7-liter is also a lot older than the EcoDiesel, with its origins dating back to 2007. While it's true that both these diesel engines powered Ram trucks, the 3.0-Liter EcoDiesel V6, and the Cummins 6.7-liter turbodiesel were aimed at very different target consumers, and powered very different vehicles: the EcoDiesel powering the Ram 1500s and the Cummins 6.7-liter powering the larger RAM 2500 and 3500 pickup trucks.
