Will Our Bigger Cummins X15 Hybrid Actually Burn More Diesel?

Everyone keeps asking if switching from a 9L to a 15L Cummins in our hybrid semi means you’ll burn more fuel, so in this video we break down the real math behind fuel usage in a series-hybrid truck. We explain why a larger displacement engine running at a constant RPM and lower average load can sometimes be more efficient than a smaller engine screaming at 90% load all day. You’ll see how going from a 250 kW to a 500 kW generator lets us either run the engine at a lower load for better efficiency, or at full load for a shorter time before shutting off, depending on the route and duty cycle. We talk about average load, constant-RPM operation, and why, in real-world logging and highway use, we don’t expect a noticeable increase in fuel consumption compared with the old setup. If you’ve ever wondered how diesel-electric hybrids can cut fuel bills while still using a “big” engine, this breakdown is for you.
