The new Cummins will not use a DEF or a soot canister. And no EGR. All smog will be handled in the engine itself. 20MPG towing will be possible.

Yep. I know. I did the CAD drawings during R&D on it last year. Sad part is, even the 6.7 cummins truly didnt need a DPF or DEF. Emissions levels were right on the line for the allowed limit so cummins went ahead and added that stuff to be safe.
