BMW has announced it is moving its next-generation iX5 Hydrogen closer to reality, beginning real-world testing of prototypes while simultaneously preparing the fuel-cell system for mass production. The automaker says validation testing is underway at its Hydrogen Competence Centre in Munich, and a new assembly phase for the third-generation system has started. This effort marks a key step in the company’s strategy to diversify its electrified portfolio beyond battery-only options.
Building the System
BMW’s engine plant in Steyr, Austria, is now installing production equipment for future manufacturing. Prototype production is moving alongside vehicle testing, with the latest assembly phase focusing on refining manufacturing processes and validating methods. The lessons learned in Munich are being transferred directly to Plant Steyr, which will eventually build the production fuel-cell systems. Josef Hochreiter, head of Hydrogen Vehicles at BMW Group, emphasized that a perfectly coordinated overall system is key for achieving the company’s goals.
The iX5 Hydrogen uses a third-generation fuel-cell system jointly developed by BMW and Toyota. The two companies have collaborated on hydrogen technology for years, and this partnership continues with the iX5. The technology allows the vehicle to function as a pure electric car without the need to plug into an external charger, relying instead on hydrogen tanks to generate electricity onboard. Engineers are currently testing and validating the interaction between the fuel-cell system, electric motor, high-voltage battery, hydrogen storage tanks, and the Energy Master control unit to ensure optimal performance.
While some automakers have shifted almost entirely toward battery-electric technology, BMW argues that hydrogen fuel-cell vehicles can complement EVs in specific applications. The strategy prioritizes long driving range, fast refueling, and versatility, addressing limitations often found in current battery-electric vehicles. The engineers are also tuning the handling and improving efficiency through better regenerative braking capability. This approach allows the vehicle to recover energy during deceleration, enhancing the overall driving experience.
Targeting Performance
BMW is targeting performance comparable to its battery-electric iX5, including a 0-60 mph run in less than five seconds. The hydrogen system is designed to maintain the driving characteristics BMW customers expect while offering an estimated WLTP driving range of up to 750 kilometers (466 miles). Refueling times are expected to be less than five minutes, significantly reducing the time spent at service stations compared to charging an electric vehicle.
BMW has confirmed the hydrogen-powered iX5 will become its first series-production fuel-cell model. When the next-generation X5 arrives, buyers are expected to have a choice of battery-electric, plug-in hybrid, gasoline, diesel, or hydrogen powertrains, though availability will depend on market conditions. The project is also a continuation of BMW’s long-running collaboration with Toyota on hydrogen technology. There has been no official word yet on whether North America will receive the fuel-cell variant, though the automaker remains committed to its “technology-open” strategy.
