I've thought E85 missed a few important points in the past; its terrific octane rating leaves a lot of potential on the table in conventional engines. So Cummins adapted an engine for E85-only operation, well and good. Could you run their "Ethos" engine on E0 safely, or would it be a detonating mess? By the PR it's E85 or nothing.
