Cummins 6.7L Gasoline Engine in a Ram?
Haven't been on this forum in a while so I am not sure if this has been discussed in the past few months. Back In February, Cummins unveiled their new fuel-agnostic strategy meaning that various e...

I worked on a Department of Energy project with Cummins a few years ago designing part of a high-pressure gasoline engine. I imagine the entire project is public now due to the fact it was funded by DoE. It was pretty amazing how much power and torque was generated by this relatively small engine, very comparable to the diesel version that was designed alongside it as part of the same project. I am sure this gas version of the venerable B series will be just as impressive.
I don't expect the cost savings to be realized in initial cost though - a lot of fancy stuff was going on with the DoE engines, and most components weren't as lightweighted as one might think. With the cylinder pressures being developed, a lot of stout parts and trick design was needed. The savings is realized in fuel efficiency and lower fuel prices. Duly noted a less sophisticated emissions system will definitely reduce the overall cost in the vehicle though.
