Before the economy took a turn for the worse in 2007, Cummins had been developing a V-6 and V-8 engine platform for use in the Dodge Ram 1500. At the time, Cummins and Dodge were racing to compete with General Motor's 4.5L turbodiesel and Ford's "Lion" V-6 and V-8 engines, all of which were also slated for 1/2 ton applications. There were also rumors that the 5.6L V-8 Cummins would become available in the Ram 2500 and 3500, possibly even as standard engines. Unfortunately, Cummins/Chrysler had to drop the campaign before their visions ever became a reality, as did the other domestic automakers. These smaller diesels would have provided efficiency and performance that their gasoline counterparts were not capable of. The interest in a Cummins powered 1/2 ton pickup never died, but the pool of potential buyers shrunk and Chrysler's financial situation became dier. The plans were ultimately scrapped, and Ram Trucks (formerly Dodge) has since chosen to offer an alternative manufacturer's engine in their upcoming Ram 1500 diesel for the 2014 model year. Yes, the Ram 1500 is getting a diesel afterall, but it will not be a Cummins; here's an oveview of what they missed out on.
