Just some information for those interested.

My 2020 i3s typically give me 250-270km range on normal daily driving, consumption at 16-17kw/100km on average, I'm not trying to save power.

Last weekend I did a longer trip, about 110km each way.
with the i3s listed with 290-305 range, this should be no problem to round trip on one charge.

It was a nice day, had the car full charged and pre-heated on the home charger, the car still sits on winter tires 155/19.
I drove the trip in EcoPro+ as it was 10-12C/56F outside and sunny, I did not need the AC on.
The trip was a mix of small roads, country roads and motorway, speed from 40-100kph, average speed just over 63kph.
I used 33% of the battery to get to my destination and was told I had 211km to go.
The next day I headed home the same route and used a bit more, 36% and an average consumption of 12.7kw/100km.

With just over 220km covered, the car told me I had another 90km to go on the remaining 31% charge.
Theoretically I should be able to get 310-320km out of a full charge.

I'm sure if you had really put an effort into it, avoided motorways and stayed below 70kph you could do better, I did notice on the part of my trip where the speed limit was 40-60kph for 25-30km, the car hardly used any power.

Whats your best numbers?

do you have the model with backup engine, or without ? And how much does it take to charge it on a longer trip ?

I have an EV, not a REX (w/backup engine), there are no REX in my country (tax reasons).
I have the 2020 i3s 120Ah, biggest battery pack they come with, it's supposed to have +/-310km / 191mi range.

I have a home charger (13Kw), so charging the car from almost empty to full is 3-3,5 hours on the i3's 11Kw charger.
If you use a public fast charger (CCS-50KW), it can charge from 20%-80% in 40 minutes, I never tried as my round trips are usually possible without recharging.
I'm sure a 20 minute "coffee/toilet" stop charge will easily get you 30% or 100km/62mi extra range.

I did the exact trip as mentioned above this weekend.
The temperature was lower (5-6c /41-43F) so I used the HVAC more, and it was VERY windy, so actually used 10% more of the battery this time. 40% each way, and had 20% remaining when I got home.

Edit:
I will probably do the trip again in a week or two, then with summer tires, will be interesting to see how much difference 155 19" and 175/195 20" will have, I think BMW say about 15-20km less.

BMW specifies 270-285 km range for the i3S 120Ah according to the WLTP test cycle, depending on tires and options.

Hmmm, I seem to remember they listed 285-300km for the i3s and 295-310km for the i3 when I ordered mine in August 2020, but maybe BMW changed them.

I see this article list similar numbers.

https://insideevs.com/news/453108/bm...ge-test-bjorn/

The car has a WLTP rating of 285-310 km (177-193 miles) depending on configuration, but BMW is more conservative and says that up to 260 km (162 miles) is possible "in everyday use in urban areas, exterior temperature: 20°C, heating/air conditioning, pre-conditioning, COMFORT driving mode."

285-310 km is the WLTP range for the i3 (non S) 120Ah. The i3S has 270-285 km. You can download the specification for both from BMW here:

New update.

I finally managed to get the same trip done on summer tires.
Exact same 220km round trip. Nice "summer day", 20C/68F, low wind.
Trip done in Eco+ mode, AC off.
It's a bit warmer than my similar winter tire run, but I now have the wider S-model 20" tires (175/195) and 15mm/20mm spacers.

First 110km leg - 13.1kwh/100km, 66,5% remaining charge - average speed 69kph.
So thats 33,5% of the charge, 0,5% more than during the winter setup at 10-12C/56F - average speed 63kph.

Return 110km leg - 13.2kwh/100km, 30% remaining charge - average speed 64kph.
Again just 0,5% more than with the winter setup, which for this leg had a 12.7kwh/100km consumption.

A difference amounting to 1% of the charge over 220km is negligible.

At home I had a remaining range of 85km vs 90km with the winter setup, making theoretical range 305km.

Seems like much of drawback from the wider summer tires is mitigated by the higher ambient temperature.
