We have some very interesting insider news about upcoming engines from Cummins and their new emissions systems. Most of what we learn here is already public information, but there is a mention of a new 7.2L Cummins turbo-diesel engine that we have not heard of before. This is unofficial, but it comes from a trusted source that received this information from Cummins. Let’d dig in.
We already spoke about news of a 6.7L Cummins Octane engine that is a gasoline-burning inline-6 engine. We now have unofficial information that this Octane engine will start production in 2026. Initially, this engine will be used in medium duty commercial vehicles such as box trucks or step-in delivery vans. This engine may get into the Ram HD pickup trucks, but we have no confirmation of this yet.
The newly mentioned B7.2L Cummins turbo-diesel is mentioned to be available starting in 2027. The reason for this timeline has to do with more stringent government emissions regulations that are referred to as EPA27 and CARB27. Will this engine also make its way into Ram HD pickup trucks? It would make sense, but we do not know for sure.
Cummins is also working on a new design for the SCR/DPF emissions cleaning system for their turbo-diesel engines. This new system is using an electric heater. It means it does not require the engine to dump additional fuel in order to raise the DPF temperatures for a regen cycle. This should improve fuel economy. This electric heater system should also come up to temperature very quickly, before the engine warms up. It means that it can provide a cleaner burning cold start.
We want to learn more about this, but in the meantime please join Kase and I in the video below and we discuss all of this news. It includes the Cummins X10 (10-liter), X15N and X15H (15-liter) inline-6 engines for big rigs. These engines include a version that burns natural gas, and a version that burns hydrogen.
