What's good economy for an EV?

In ICE vehicles, I readily know what good fuel economy is as I think most here do. For example, I think it's generally known by everyone that 5.0L/100km and lower is considered excellent fuel economy.

But what's the EV equivalent and how do you express it?

Today, I achieved 5.4km per kWh. Or 18.52kWh per 100km

1) What's considered good? What's considered excellent?

2) How do you best express it? Km/kWh or kWh/100km?

I express by kWh/100km, makes it easy to compare to L/100km. 18.5 is good for the winter. Expect sub-15 come spring time especially when you neither have to heat nor cool.

We've had sub 20 glimpses in the city when temperatures have been up to +10, but our average is still in the low 30s. I also calculated I've been averaging about 6.8 eL/100km. That's what I've actually paid per 100km (I find 1 kWh in only = 0.85 kWh into the battery), divided by the average cost of gas. I'm still paying for the one time I dint realize I was paying $6/hour for a 6.6 kW charger. I expect it to drop closer to 3 eL/100km in the warmer months as kWh/100 km drops and gas prices increase.

From experience, I'd say anything below 20 l/100 km is pretty good, especially in winter. I see it as the 10 l/100 km barrier. The most efficient EV I've ever driven was the 1st-gen Ioniq, the one that looked like a Prius. It stayed between 10.7 and 11 kWh/100 km while I had it.

Early EV's like the Focus Electric and BMW i3 were pretty frugal, being small cars, but today's EV's are mostly uber powerful beasts, and they guzzle kilowatts. Our CX-90's lifetime avg is in the 30's, and mid-20's is the most typical I see. The really quick Macan impressed me with an even 22 for the week.

So I find the Buzzfork's 18.5 pretty good! Will try to get inot one this year, I have not driven those yet. In the Leaf in two weeks  :)

I"m surprised you didn't get comfortable with the units with the Prime - there's a kwh economy rate on it. 

I'm with you, though.  It's completely new territory, and something that makes me uncomfortable, because I don't have a benchmark in my head.

Nah, I just used L/100km. That made sense  and worked.

It's -30 now so it's up to 75 kWh/100km season lol. It settles down to the 30's once the cabin is warmed up.
