2 0 Twenty Mile Marketing Sales Pitch

Although I understand the reason that companys, mfg, and business use marketing for products. All consumers should have some critical (do your homework) and factual thinking on the following issue.
What does Enginer, PIS, Ford, and Toyota well all have touted(marketed) 20 twenty mile pure EV..

Enginer makes the mixed mode claim (not sure which kit or kit and vehcile mix get this)
PIS more about high speed PHEV claim
Ford C Max plug in makes the statement of 20ev miles with full charge
Toyota Gen 3 Plug in oem makes the same statement of 20 mile EV

All may make this marketing statement however I think Ford and Toyota are more inclined to be in
a place I like to think of as (the ballpark of truth) aka real world proven first hand witness reality. Otherwise like me stating I have found big foot..............
