3 Series (G20) BMW i3 2022 Spyshots

Out of curiosity, do you get an average speed across Trip A also?

Have I done my maths correctly?

11,612 km
1,898 kWh

1,898/(11,612/100) = 16.35 kWh/100km

1,898/(11,612/100) = 16.35 kWh/100km

That's what I had. I asked about the speed because I'm wondering which of the 4 phases of the WLTP cycle @Swiss_ZH driving profile mostly closely represents. @CrunchSlaughtered suggested that 20kWh/100km is reasonable, and Swiss_ZH has demonstrated a lot less in the real world. I'm just wondering (well, calculating in a spreadsheet) if both statements are likely to be true (both are possible I'm sure).

Spoiler: Stuff

This is the 'simulation/model' I was building for the iX3. Work in Progress at the moment, let alone the fact that the regen calculations are 50% guesswork, the're not adding up right anyway.

I'm just looking for indications of how much different things affect different parts of the cycle.

I mostly use it for my daily commute (50 km combined) which is about 2/3 highway and 1/3 city. In the city my average speed would be about 20 to 30 km/h (lots of stop and go) and on highway about 100 to 110 km/h (125km/h top speed). Not much vertical meters on the way (which is unusual in Switzerland).

There is a much easier way - it is given in the photo as 163,5 Wh per 1 km, just have to multiply it by 100.

I prefer to perform the full calculation.

Off topic, but....

Calculation satisfaction.
