Winter range is reduced, no different than with ICE's. Remeber, the energi does not need to warm up (idle) before you start driving. My Energi has 5500km on the odometer with 4tanks of gas doing mixed driving. Compared to my 1.6 ecoboost escape im laughing. In the summer driving my new car home on the 401 I was able to get 65km in EV mode before the ice kicked in. How??? Driving in the fast lane with no traffic and setting the pace @ 130km/h. No AC, or radio had the sun roof open and cruised.
