Thanks for the replies. This will be my wife's car and her commute is 3 days a week at 43 miles round trip with about 2/3 interstate. Then all other trips are in stop and go, hilly suburban area mom taxi trips. Most of the kids activities are in a 10-15 mile radius, so our hope was take kids, come back home, plug in to L2 charger, go get kids later, etc and really realize the benefits of the Energi over the Hybrid.
