It's also the worst of both worlds at the same time, since you have the issues of both petrol engines and battery electric cars. Your 50 km of pure electric range drops to like 20 km in the winter, and after that you're driving on your cold-ass petrol engine and lugging around a heavy battery.

I drove my mom's BMW 530e plug-in hybrid to the store and back (5 km in each direction). At the end, I think we had 5 km of range left. Granted, it did handle a grocery run just on battery and the heating system worked well, but that was about all that it had. The NEDC rating for the car is 50 km of electric range.
