Turtle 0F DEGREES

At 0F, the engine will run to warm up cabin and battery, so it starts at moderate load and runs rich to warm up the exhaust that has a heat exchanger on it for the heater core and battery cooling/warming, that may be burning lots of fuel.

On my C-Max PHEV, if I look at instant MPG, at 55MPH and when engine is charging battery it will show 20MPG, so you might be fighting that.
