Direct from a Cummins article:
Cummins’ biggest embrace yet of a growing menu of low carbon fuels will be applied across their B Series, L Series and X Series engine lineup. Fuel choices will include diesel, natural gas, hydrogen, propane or gasoline. Once spec’d, engines will run on one fuel only.
The first engine expected to roll out in 2024 will be a 6.7-liter gasoline-ready option, which Cummins sees as a good fit for pickups and other vehicles needing “diesel-like durability and performance,” according to Cummins’ president of engine business Srikanth Padmanabhan. The motor shouldn't be any heavier than the 6.7 diesel that is already in Ram pickups. So why wouldn't Dodge use it since the Hemi is going away and they clearly are making the move to inline 6 cylinder engines? Never say never.
