BMW is continuing development of the next-generation iX3, with a prototype recently spotted testing near the Arctic Circle. The all-electric SUV will be the first production model based on BMW’s Neue Klasse platform, a new technical foundation planned for a broad range of future models.

The second-generation iX3, known internally as the “NA5,” is expected to look substantially different from the current SUV. BMW is testing the vehicle’s battery pack and overall configuration in extreme winter conditions ahead of its planned European launch in the second half of 2025.

Neue Klasse design arrives on an SUV

Camouflaged prototypes suggest the new iX3 will draw heavily from the BMW Vision Neue Klasse concept. The front end appears to feature wide, horizontal headlights and a revised interpretation of BMW’s double-kidney grille.

Compared with today’s iX3, the prototype appears more rounded and less upright. Broad wheel arches house large wheels that could measure 20 or 21 inches, although BMW has not confirmed the production specifications.

Spy footage from CarSpyMedia does not show the cabin. BMW’s Vision Neue Klasse concept used a minimalist interior with relatively few physical controls, but it remains unclear whether the production iX3 will follow that approach or use a more conventional layout.

New battery technology

The new iX3 is expected to introduce BMW’s sixth-generation round-cell battery technology. BMW says these batteries can provide a 30% increase in range and charging speed compared with its current batteries.

The cells use a standard 46-millimetre diameter and are designed to increase energy density. That could allow BMW to improve efficiency without relying on an excessively large and heavy battery pack, though final battery capacity, range and charging figures have not been announced.

Planned iX3 lineup and production

BMW is expected to offer the NA5 with four initial versions: the 40, 40 xDrive, 50 xDrive and M60 xDrive. The naming indicates that both rear-wheel-drive and all-wheel-drive variants are planned, but detailed power and performance specifications remain unavailable.

A more focused M variant, reportedly carrying the internal code “ZA5,” is also planned for a later date. BMW has not yet provided timing or technical details for that model.

Unlike the current iX3, which is produced in China, the next-generation electric SUV will be assembled at BMW’s new plant in Debrecen, Hungary. European availability is scheduled for the second half of 2025, putting the iX3 at the front of BMW’s Neue Klasse rollout.
