Overview

• BMW has started prototype production of its third‑generation fuel‑cell systems at competence centres in Munich and Steyr.
• Series production of fuel‑cell stacks is scheduled to begin in 2028 at BMW Group Plant Steyr, where new lines and test rigs are being installed.
• Key hydrogen components, including a new high‑voltage control unit called the BMW Energy Master, will be manufactured in Landshut, with prototype units set to come from Dingolfing starting mid‑2026.
• The latest system is about 25% smaller with higher power density and improved efficiency, and BMW cites fast refuelling of roughly three minutes and iX5 prototype range exceeding 500 km.
• The technology is being jointly developed with Toyota for use across multiple platforms, and BMW says initial sales will target markets that have sufficient hydrogen refuelling infrastructure; reports suggest a future X5 variant is a likely candidate.
