It's an electric car, so no oil consumption (parent talks bout mpg)
There is an mpg equivalent for electric cars based on the idea that 1 US gallon of petrol is 33.7 kWh.
Cool, didn't know that, thanks
That's 70% of the entire energy contents of the gasoline. You don't get anywhere near that kind of efficiency even on large electrical generators. 16.2 kWh is way more realistic.
