I own the 2017 EX standard hybrid, NOT plug in. Don't forget however, that even if you deplete your 27 miles of all electric range, you will still be recharging with regen braking,,,,,,, so your vehicle will still run partial EV, ICE, and true HYBRID mode (ICE & EV), it will just run like mine, standard hybrid, still giving you great mpg's......... previous poster is correct, it would be best to charge up everyday, to top off your battery so you will gain from its full potential.
