BMW begins road tests of hydrogen EV X5

BMW has begun real-world tests of its i-Hydrogen Next, an X5 paired with EV and hydrogen tech.

The BMW i Hydrogen Next is an all-electric vehicle fueled by the reaction of hydrogen and oxygen in a fuel cell. The German automaker firmly believes that hydrogen fuel cell technology can replace internal combustion engines, plug-in hybrids (PHEVs), and battery-electric vehicles (BEVs) as the future of mobility.

Toyota and BMW are collaborating on hydrogen cars, with BMW planning to launch the i Hydrogen Next in 2022.

The i Hydrogen Next will see limited production, as BMW plans to devote more energy to EVs in the coming years.

According to multiple sources including Overdrive and Slashgear, both online auto journals, the testing that began this week will aim to tune the software controlling the car’s driving and operating functions, the automaker has said, following static tests of the fuel cell system and hydrogen tanks.

BMW has been experimenting with hydrogen fuel cell technology for decades.

But BMW’s efforts in this field are still a few rungs below Toyota and Honda, which have already fielded hydrogen fuel cell cars.

“Hydrogen fuel cell technology can be an attractive option for sustainable drive trains – especially in larger vehicle classes,” says Frank Weber, member of the Board of Management of BMW AG responsible for Development.

“That is why road testing of near-standard vehicles with a hydrogen fuel cell drive train is an important milestone in our research and development efforts.”

According to the automaker, hydrogen fuel-cell drivetrains could become an attractive alternative to EVs, but with a planned small-series production it’s not quite going all-in, unlike Toyota and a few other automakers that have marketed unique sedan designs for years.

BMW is also aiming to get practical experience using this drivetrain in real-world conditions.

The i Hydrogen Next will pair BMW’s eDrive technology already rolled out in vehicles like the iX3 with a hydrogen fuel cell technology developed along with Toyota—one of the other major players in this field.

The vehicle is largely based around architecture and technology borrowed from existing vehicles, rather than being a model developed entirely from scratch, which suits the model’s planned small-series production volume.

The SUV promises 374 hp—the same as the most powerful inline-six gas engine in the automaker’s lineup, as BMW points out.

“The energy stored in the performance buffer battery is generated in a particularly efficient way during driving by recovering energy from coasting overrun and braking phases,” the automaker said.

It also stated, “The hydrogen needed to supply the fuel cell is stored in two 700-bar tanks made of carbon-fiber reinforced plastic (CFRP), which together hold six kilograms of hydrogen.

“Its precisely controlled reaction with oxygen in the fuel cell generates electricity, while water vapor is the only emission produced by the drive train.
