BMW’s iX5 Hydrogen vehicle has entered a “critical” phase after four years of development work, the automaker announced.

The first iX5 Hydrogen vehicles are now in a 100-strong pilot fleet, which is being deployed internationally for demonstration and trial purposes, with locations including the UK.

The pilot fleet was announced earlier this year.

The vehicles are built in the BMW Group’s pilot plant at its Research and Innovation Centre (FIZ) in Munich.  

Oliver Zipse, Chairman of the Board of Management of BMW AG said: “Hydrogen is a versatile energy source that has a key role to play in the energy transition process and therefore in climate protection.”

The iX5 can hold six kilograms of hydrogen, giving it a range of around 313 miles.
