Having owned a prius prime
Having owned a prius prime for 2 years I can tell you filling with fuel every 6 months is fantastic, most driving is within my Town on electric. Prime always revertes to ev mode on start, with covid no need to travel farther.but when we traveled to visit friends in oregon hybrid mode kicked in automatically easily travelling at 70-80 mph no need to look for charging. Summer time I easley get 50-55 km of ev driving a little less in winter. no maintenance needed oil change once a year. Totally reliable as all Toyotas are.
