The i4 M60 is now listed on the BMW website:
https://www.bmw.nl/nl/modellen/bmwi/...m60-xdrive.bmw (in Dutch). Unfortunately not yet in the configurator.
The differences I get from this compared to the M50 are:
Power: 442 kW (601 hp) instead of 400 kW (544 hp)
Acceleration 0–100 km/h: 3.7 sec. instead of 3.9 sec.
Power consumption, combined WLTP: 21–16.6 kWh instead of 19.7–17.9 kWh
Electric range, WLTP: 432 - 551 km instead of 469 - 513 km
Recharged range after 10 minutes of fast charging: 141 - 185 km instead of 135 - 173 km
Empty weight: 2,285 kg instead of 2,290 kg
So it seems to have become about 5-10% more efficient with 10% more power.
Dealers don't know anything about prices and delivery yet. Anyone here by any chance?

No idea whether anything will change now with the 35 or 40 by the way, I can't find any differences there.
