There's been quite a few studies questioning the current focus on EVs with ranges of 400km and more. Largely because they are so heavy and are therefore not very energy efficient. The argument is that most peoples daily commute is less than 50km (in Europe), but they still by an overly heavy EV for the 5-10 times a year they go on longer trips. Instead a plugin hybrid could be much more efficient, because you can use it in EV mode for your commutes, but you can still use the car for long trips, without the significant weight (and corresponding inefficiency) increases of an EV. I suspect this is very much a function of the driving pattern, and I suspect in the mid-term future this will change with more efficient battery technology.
