Overview
- Official WLTP figures rise to 501 km for the single-motor Countryman E and 467 km for the dual-motor SE ALL4.
- Efficiency gains come from a silicon-carbide inverter, a slight increase in usable battery capacity to 65.2 kWh (gross remains 66.5 kWh), and reduced‑friction front wheel bearings.
- DC fast charging remains unchanged at a claimed 10–80% in under 30 minutes with peak rates around 130 kW.
- Production of the updated models begins in Europe in March 2026, with availability and EPA-rated range for other markets yet to be announced.
- Mini presents the change as a rolling technical update rather than a facelift, mirroring BMW Group’s broader inverter upgrades also applied to related iX1 and iX2 models.
