The Optima Hybrid received impressive updates for the 2016 model year, and the new 2017 plug-in builds on that solid foundation with an extended EV range. This plugged hybrid has a coefficient of drag of .24, achieved via active grille shutters, aero-optimized wheels, and a special rear diffuser that hides the exhaust outlet. Its quick charge interval means the Optima Plug-In will be a viable alternative even for those with rather long commutes or tight turnaround times.
