The range drop applies only to electric mode, and it doesn't drop by half unless you're driving very slowly (in other words, you spend a lot of time with the heater on and don't go very far). Pre-conditioning the cabin while the car is plugged in helps tremendously in moderately-low temperatures. There's a setting on the center console screen to adjust how aggressively the Volt uses the engine for heating.
