Don't think that this particular engine had fuel economy as the top of the goal list. Seems the EV is there for that purpose. And by the way when we all bought our ICE performance muscle cars who bypassed a model because of poor fuel economy, back in the day or even now in the day. ( hmmmm is "Now in the Day" a new term shruggy laugh2 laugh2 ) Just feel good that a performance ICE is still available or ask Mopar to lower the compression and tune it for "fuel economy down down. "New H.O Hurricane 6 (with more government restrictions and hoops to jump through with obviously) has worse fuel economy than 5.7 Hemi". Who would have thought?
