Most And Least Efficient EV's

When talking about electric cars, the main list of criteria is charging speeds and range, but electricity prices have been creeping up to such an amount that I think it’s worth finding out what the most efficient cars are in Wh/mi instead of MpKwh which gives you some irrelevantly small number.

Something to address before finding out just which cars have the energy usage of a dishwasher and which have the energy usage of a LED light bulb, we need to find out how much it costs to fill up an ICE car and full EV too. The best car to use for this comparison is the popular BMW X3. At the current 146.50 pence per litre, a 65 litre fuel tank in the X3 30i will cost £95, not as much as I was expecting when you here about £200 horror story fill ups. The X3 30d has a slightly bigger fuel tank at 68l and add to the fact that diesel is going for 159.39 pence per litre, means that it does amount to £108 instead. As for the EV, a rapid charge costs 69.2 pence per kilowatt hour (an ultra-rapid charge is slightly more). Multiply that by a 74kwh usable battery capacity and you have a £51 fill up. That’s a reasonable amount less, but not enough to forget about efficiency. This is especially true when to my surprise (and great disappointment) the diesel X3 30d cost 16.8 pence per mile compared to the electric iX3. A big straight six engine more efficient than electric motors, I’m not sure where the world is coming too.

You’d expect the most efficient cars to be some overcomplicated small hatchback like the Honda-e, much is the same story with ICE cars, I’m looking at you Honda Civic. However, as I’ll show you in this list of the top 5 most efficient EV’s, some larger cars creep into the top spot, as a rule of thumb, 280 WH/mi or less is good, 320 WH/mi is alright and any more is bad
