Pure EVs are incredibly efficient, and that's the only way that we've got anything resembling acceptable range. The energy density in the battery technologies available today pales in comparison to the energy density of a gallon of gasoline. I think to the point that 100kWH battery is the equivalent of something like 5 gallons of gas.
This is also why harsh conditions impact range of EVs much more than gasoline cars. The efficiency is so dialed in for an EV, that even a minimum hit to it makes a big difference in range. Internal combustion is so inefficient by comparison, that we often don't notice the drops in efficiency.
I’m not talking about efficiency of converting battery vs gas energy into work, I’m talking about efficiency of how far the same amount of work (whether gas- or battery-derived) can move your vehicle. So primarily talking about aerodynamics here (and I guess regenerative braking efficiency as well)Pure EVs are incredibly efficient, and that's the only way that we've got anything resembling acceptable range.

Consider RAV4 conventional hybrid (my real world mileage over 5 years is 38.5mpg), vs Volvo xc60 phev - when driven is gas mode its rated for 28mpg
That suggests, if you took the rav4 body and frame and the xc60 body and frame, and you put in the same electric motor and a battery pack equivalent to 10 gallons of gas in each one, you’d get the following range:
RAV4: 385 miles
Xc60: 280 miles
That’s a MASSIVE difference
I’m just surprised that Toyota still seemingly has such a huge edge in this type of efficiency (I’m guessing from some combination of aerodynamics and regenerative braking technology). And if they ever get around to adopting EV technology I’m excited to see what their expertise in efficiency will mean in EV form
