MINI has announced a technical update for its all-electric Countryman lineup, with the MINI Countryman E now delivering up to 501 kilometers of range under WLTP testing. The updated models arrive in March 2026 with efficiency improvements centered on a new silicon carbide inverter and increased battery capacity.
Highlights
- Extended range: MINI Countryman E achieves 501 km (WLTP); Countryman SE All4 reaches 467 km
- Battery upgrade: Net capacity increased to 65.2 kWh with new silicon carbide (SiC) inverter for improved energy conversion
- Fast charging: DC charging enables 10-80% battery replenishment in under 30 minutes
- Aerodynamic efficiency: Drag coefficient of 0.26 contributes to range optimization
Technical Improvements Behind the Range Increase
The range extension results from three primary engineering changes. The new silicon carbide inverter minimizes power losses during energy conversion. Battery net capacity has increased to 65.2 kWh, providing more usable energy storage. Friction-reduced wheel bearings on the front axle lower rolling resistance.
Energy consumption figures reflect these efficiency gains:
- MINI Countryman E: 17.4 kWh/100 km (WLTP combined)
- MINI Countryman SE All4: 18.5 kWh/100 km (WLTP combined)
Both variants produce zero direct CO2 emissions and achieve CO2-class A ratings under German regulations.
Interior and Cargo Specifications
The Countryman maintains its position as MINI’s largest model with variable cargo capacity up to 1,450 liters. The interior features a central 24 cm OLED display for infotainment and driver assistance system controls. Advanced driver assistance enables autonomous driving functions up to Level 2.
Exterior Design and Aerodynamics
The updated Countryman incorporates aerodynamic optimizations contributing to its 0.26 drag coefficient. The Favoured Trim package includes:
- Exterior color: Blazing Blue
- Roof and mirror caps: Vibrant silver finish
- Wheels: 20-inch alloy with Windmill Spoke design
