Hemi to be replaced by inline six?

This was announced a while back, but Stellantis has finally released details on the new twin-turbo 3.0 liter inline six that might replace the Hemi in the Ram 1500 and other Stellantis vehicles. Pretty impressive power numbers!

    I6 will always have more low end torque.


    Why?

    For 1 thing, a V design will have gravity causing more friction on 1 side of piston. Most inline engines mount to wear piston runs vertically
    But I think many times it has a lot to do with what the engineers expect engine to be used for. Back when I6 or V8 was the option, we expected the buyer of the lower cost I6 would be more interested in a engine that got the job done but not as fast.

    It’s an inherent design. I believe it has to do with all the cylinders being inline.

    Only if "all else is equal"...which of course, it never is.

  • Love it !


    Maybe they should have architected this new in-line 6 with hemi chambers...so they can continue marketing it as a 'Hemi'...

    Pent-roof is a better, and some refer to it as a "pent-roof hemi"...which most modern ICE's use

  • Exciting times but no Hemis and none of these new engines will be sold in California after 2034.
