BMW Plans Next iX5 Hydrogen SUV With Longer Range and Faster Refueling

BMW Continues Investment in Hydrogen Mobility

While battery-electric vehicles dominate headlines, BMW is continuing to develop hydrogen-powered alternatives. The company’s upcoming iX5 Hydrogen SUV represents its latest effort to refine fuel-cell technology, aiming to address long-standing limitations such as range and packaging efficiency.

Hydrogen fuel-cell vehicles have struggled to gain mainstream traction, largely due to limited infrastructure and high costs. However, BMW believes there is still a role for this technology, particularly for drivers who prioritize quick refueling and extended driving range.

New Storage System Improves Efficiency

A key upgrade in the next-generation iX5 Hydrogen is its redesigned fuel storage system. BMW has introduced a solution known as “Hydrogen Flat Storage,” which is engineered to maximize space utilization while increasing capacity.

Unlike traditional cylindrical tanks that can intrude into the cabin or cargo area, this new system is more compact and better integrated into the vehicle structure. The result is improved interior space without compromising fuel volume, addressing one of the common drawbacks of earlier hydrogen vehicles.

Increased Hydrogen Capacity and Driving Range

The updated storage system enables the SUV to carry at least 7 kilograms of hydrogen, compared to approximately 6 kilograms in the current version. While the increase may appear modest, it has a meaningful impact on driving distance.

BMW estimates that the new model could achieve up to 750 kilometers (around 385 miles) on a full tank, representing a significant improvement over the roughly 300-mile range of the existing iX5 Hydrogen.

Another advantage remains the refueling experience. Filling the hydrogen tanks is expected to take under five minutes, making it comparable to traditional gasoline vehicles and far quicker than most EV charging sessions.

Advanced Tank Design and Safety Standards

The storage system itself is built using seven interconnected chambers made from carbon-fiber-reinforced materials, forming a single integrated unit. Each chamber is designed to handle pressures of up to 700 bar, which is standard for modern hydrogen vehicles.

These tanks are housed within a protective metal casing that matches the footprint of BMW’s next-generation battery packs. This design decision allows the company to standardize production processes across different powertrain types.

Shared Platform Enables Flexible Production

BMW’s upcoming X5 lineup will be built on a flexible architecture that supports multiple propulsion systems. The next-generation model, internally known as the G65, will be offered with gasoline, diesel, plug-in hybrid, battery-electric, and hydrogen fuel-cell options.

By aligning the hydrogen system’s packaging with battery-electric components, BMW can produce various versions of the X5 on the same assembly line. This approach is expected to reduce manufacturing complexity and improve cost efficiency, especially as demand for different powertrains fluctuates across markets.

Collaboration With Toyota on Fuel Cell Technology

The hydrogen system in the new iX5 is part of a continued partnership between BMW and Toyota. The upcoming version will feature a third-generation fuel cell system, which is said to deliver improved performance and efficiency compared to earlier iterations.

This collaboration allows both companies to share development costs and accelerate progress in a segment that still requires significant investment. The current iX5 Hydrogen has only been deployed in limited pilot programs, primarily in Europe and California, but the next version is expected to move closer to broader availability.

Timeline and Market Outlook

BMW plans to begin production of the new hydrogen-powered iX5 around 2028, positioning it as a long-term component of its electrification strategy. While battery-electric vehicles remain the primary focus, hydrogen is seen as a complementary solution in specific use cases.

Challenges remain, particularly around the availability of hydrogen refueling stations. Without significant infrastructure expansion, adoption is likely to remain limited to select regions.

However, BMW’s continued investment suggests confidence that hydrogen could play a role in future mobility, especially where fast refueling and long-distance driving are critical factors.

Balancing Technology Paths in a Changing Market

The development of the iX5 Hydrogen highlights a broader industry trend: automakers are exploring multiple pathways to reduce emissions rather than relying on a single solution.

For BMW, maintaining flexibility across powertrain options may provide a competitive advantage as regulations, consumer preferences, and infrastructure evolve. Whether hydrogen can achieve meaningful scale remains uncertain, but advancements like those in the new iX5 indicate ongoing progress.
