You also forget that cold
You also forget that cold dramatically affects the efficiency and power output of the batteries, which may never achieve a full charge from the gas engine in winter, hence using the engine almost exclusively in winter.
I hope that engineers can
I hope that engineers can work out this battery life problem for cold weather. Especially if the US is going to grow the all electric car market. I guess I'll settle on my next car being a hybrid. Does anyone have a feeling for if fuel cells would be negatively impacted the same way? Food for thought.
