The sixth generation of BMW eDrive technology (Gen6) makes its debut in the brand's all-electric flagship model via 4695 cylindrical lithium-ion cells. These cells feature a volumetric energy density that is 20% higher than the prismatic cells used in the Gen5 system. This high-voltage battery is expected to significantly boost the range of the new BMW i7 while enabling shorter charging times. The new BMW i7 is set to celebrate its world premiere on April 22 at Auto China 2026 in Beijing. 

Innovative Hydrogen Tank Technology for the BMW iX5 Hydrogen 

In addition to the battery updates, BMW has announced a new and innovative hydrogen storage technology for the BMW iX5 Hydrogen. The new configuration and size of the tanks are designed to enable an impressive range of up to 466 miles (750 km). 

A major advantage of the BMW Hydrogen Flat Storage system is its highly efficient use of vehicle space. It is designed to be compatible with the Gen6 high-voltage battery housing, ensuring that no interior room is sacrificed. This allows models equipped with fuel cell technology to be manufactured on the same production lines as other powertrain variants. Furthermore, the 700-bar high-pressure hydrogen tanks benefit from the mechanical protection provided by the vehicle's structural frame. 

The new flat tank system consists of seven interconnected high-pressure tanks made of carbon-fiber-reinforced composite material, all integrated into a robust metal frame and connected in parallel. Rather than using individual separate canisters, several composite chambers form a single closed unit managed by a central main valve. This optimized storage concept is what makes the extended range of the BMW iX5 Hydrogen possible. In total, the system can store at least 15.4 lbs (7 kg) of hydrogen and can be fully refueled in less than five minutes. As is standard for BMW hydrogen vehicles, the refueling process remains safe, clean, and fast.
