BMW iX3 40 in 2026: what the Neue Klasse numbers mean
BMW's official iX3 40 specifications explained: battery, range, charging, performance and the checks to make before ordering.

The official specification
BMW says the iX3 40 produces 235 kW (320 hp) and 500 Nm, reaches 100 km/h in 5.9 seconds and uses an 800-volt electrical architecture. Its published WLTP energy consumption is 17.3–14.5 kWh/100 km. Wheel size, equipment, weather and driving conditions can change real use.
What 300 kW charging does—and does not—promise
A maximum charging figure is a peak, not the speed maintained through an entire session. Before buying, ask for the model's charging curve, battery preconditioning behavior and local fast-charger compatibility. Home charging power and installation matter more for many daily routines.
The buyer checklist
Confirm the precise battery, wheels, standard equipment, warranty, software services and delivery market in writing. Test rear-seat comfort, luggage loading and visibility. Compare insurance and tyre costs with another electric SUV before treating the headline range as the deciding factor.
