So EVs are so new they are so hard to compare apples to apples.

All I care is how far it can go.

What are the real world range of each car!

and price divided by range.

to get $ [PRICE OF CAR] / km in real world

i think the Nissan Leaf would top this chart.

The price of electricity varies quite a bit based on supplier and if you use public charging or not. For us we have a 30kwh leaf with 85% health remaining that can get 160km on a charge.

So battery capacity is about 24kwh (30x0.8)
We lay just under 10c/kw if we charge overnight

So being lazy and rounding off $2.40 will do 160km

The alternative is my dash board says on average I'm getting 6.7km to the kWh, so 10c gets me that far.

Aot of factors will determine your range though, we have 2 almost identical leafs and my partners averages more despite extra weight on board with a kid. The big impacting factors are:

Weight
Temperature
Speed
Driving style
Regen breaking
Battery capacity
Wind

Used cars are hard beacuse battery heath/rangers varies over model, ages, use etc.
Here is a new car price guide that is not that old.

I'm not quite sure what you're looking for here, because calculating a figure that's based on the relationship between cost and range leads to ridiculous outliers, eg a $4k car that can do 50km is going to be better on this metric than a $10k car that can do 120km, but obviously this defeats the purpose of it given you say range is all you care about.

So I can't really see the value in comparing all cars in some universal measurement to find 'best value EV', but I guess it could well be a useful metric if you're wanting a way to choose one car over another, eg an MG ZS vs BYD Atto. But, then again, isn't that just a matter of finding the car within your budget that has the longest range?

Anyway, I think it's a fairly reductionist position to say that range is all that matters as there are so many other factors that come into account - eg, personally I'd be swayed towards choosing an LFP-equipped car with a slightly lower range at 100% than a similar car with different battery chemistry. And that's before one considers non-battery related factors (eg size, looks, comfort, driving feel, tech, usability...).

John Cadogan (AutoExpert YouTube channel) recently ‘reverse engineered’ an LDV T60e to come up with some specs and pricing for the Oz market. He used the MG ZS as his basis for calculations. It probably would have been simpler to just download the spec sheet off the LDV NZ website, but that wouldn’t have proven what a clever engineer he is……

Some of his estimates were close, some not.

The OP doesn’t state whether they are talking new or used. If it’s new, I very much doubt the LEAF is the lead contender using their metric.

And of course only tells half the story. $9K 2015 Leaf with a brand new $20K battery still has a 2015 head unit and computing power, even if it does suddenly get you 250km.

This site might have what you’re after but only using WLTP range not real world actuals - https://evdb.nz/range-vs-price

ok let's ignore a used Nissan Leaf - I still think it will win this battle (if the route was short lol)!

so Atto 3, ZS EV, Model Y 2WD and EV6 2WD ... (feel free to list other contenders! i can't think of any?)

which one has the best $ / km ?

the WLTP is 100% useless for this exercise and I don't know the real world range of these doing the same route.

maybe I should take a week's leaf and do this exercise myself!

thanks i read the FB link - it's based on some correction factor applied to WLTP

which may (unlikely) or may not be accurate

A standardised test (such as WLTP) is the only way to do this. Otherwise you introduce so many variables that any figure you get will be meaningless. While not ‘real world’ it is the only way to compare vehicles. Otherwise the whole exercise becomes “useless”. Because, Science.

I still won't use WLTP.

I think I'll do my own calculations using Bjorn's real world data.

If they are all WLTP then isn't it apples v apples regardless of the weakness of the WLTP standard?

i've just done a quick exercise using the worst and best performers on Bjorn's real world data and compared to WLTP

they are all between 81-84% of WLTP!

[calculated using 90kph]

so it works!

(at 90km/hr at least ... do i want to compare at 120kph .... i think Aero might win here - anybody want to guess?)
