Below is a publication-ready version based on BMW’s latest September 2026 update, with the external links removed from the article text. BMW says the iX5 Hydrogen is currently undergoing real-world testing while fuel-cell production preparations are progressing in parallel, with series production planned for 2028.
BMW iX5 Hydrogen: Series Production Is Getting Closer
BMW is moving closer to bringing hydrogen-powered mobility into series production with the upcoming BMW iX5 Hydrogen. The company is currently conducting extensive real-world testing of its hydrogen SUV while simultaneously preparing the production process for the next-generation fuel-cell technology. BMW plans to start series production of the iX5 Hydrogen in 2028, making it the brand’s first hydrogen-powered series-production vehicle.
Testing Continues Under Real-World Conditions
The BMW iX5 Hydrogen is currently going through a comprehensive testing programme designed to evaluate its performance in everyday driving conditions. BMW previously tested a global pilot fleet in more than 20 countries, covering almost one million kilometres in different climatic and road conditions. These tests provided BMW with valuable information for developing the production version of the vehicle.
The latest testing phase is an important step before the vehicle moves into series production. BMW is testing the complete hydrogen-electric drivetrain, including the fuel-cell system, hydrogen storage technology and other vehicle components.
Third-Generation Fuel Cell Technology
At the centre of the BMW iX5 Hydrogen is a third-generation fuel-cell system developed jointly by BMW Group and Toyota Motor Corporation. According to BMW, the latest system is more compact, powerful and efficient than the previous generation.
The fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen from the surrounding air. The electricity is then used to power the vehicle’s electric motor. Unlike conventional combustion engines, the fuel-cell system does not produce tailpipe CO2 during driving.
BMW is also preparing the next assembly phase of the third-generation fuel-cell system in Munich, while BMW Group Plant Steyr is getting ready for future series production.
Hydrogen Storage and Long Driving Range
One of the key technologies in the new iX5 Hydrogen is BMW’s Hydrogen Flat Storage system. The system uses seven high-pressure hydrogen tanks integrated into a compact structure. BMW says the vehicle can store at least seven kilograms of hydrogen and can be refuelled in less than five minutes.
BMW is targeting a range of up to 750 kilometres under WLTP conditions. The flat storage design is also intended to make efficient use of the vehicle’s available space without compromising cabin room.
Production Preparations Are Already Underway
BMW is not waiting until 2028 to prepare its manufacturing network. Production-related work for the hydrogen drivetrain is already progressing at several BMW facilities.
BMW Group Plant Landshut has started pre-series production of an important control unit known as the Energy Master for the hydrogen drivetrain. Meanwhile, Plant Steyr is preparing for future production of the third-generation hydrogen drive system.
The iX5 Hydrogen is also designed to share production infrastructure with other BMW X5 drivetrain versions. This supports BMW’s strategy of offering multiple powertrain technologies within the same model family.
BMW’s Technology-Open Strategy
The iX5 Hydrogen is part of BMW’s broader technology-open approach. The new BMW X5 family is being developed around multiple drivetrain choices, including petrol, diesel, plug-in hybrid and battery-electric power, with hydrogen fuel-cell technology joining the range later.
Hydrogen offers a different approach to electric mobility by combining electric driving with long-range capability and very fast refuelling. This could make fuel-cell vehicles particularly interesting for drivers who regularly travel long distances and do not want extended charging stops.
Conclusion
The BMW iX5 Hydrogen is moving from pilot testing toward a production-ready hydrogen SUV. With real-world testing continuing and manufacturing preparations already underway, BMW is building the foundation for series production in 2028.
