powertrain for the BMW i Hydrogen NEXT-03

BMW i Hydrogen NEXT arriving in 2022 with 368 horsepower

The future BMW i Hydrogen NEXT fuel cell electric vehicle is scheduled to be unveiled in 2022, equipped with a state-of-the-art hydrogen-based powertrain. BMW Group will launch the second generation of its hydrogen-based powertrain in 2022 on a small series of the BMW i Hydrogen NEXT based on the current X5 generation.

The prospects of offering a larger-scale series production BMW FCEV depend very much on market conditions, requisite infrastructure, competitive pricing and customer requirements. BMW estimates that it will be able to launch such a vehicle in the second half of this decade at the earliest.

Coming back to the BMW i Hydrogen NEXT, the new trial model will be produced in a small series on a modified G05 X5 chassis. Much of the high-tech exterior styling will be transferred from the concept car that was shown last year at the IAA Frankfurt.

The second generation of the hydrogen fuel cell powertrain architecture generates up to 125 kW / 170 PS (168 hp) of electric output from the chemical reaction between the hydrogen in the vehicles storage tanks and oxygen in the ambient air.

Essentially, the chemical reaction between hydrogen and oxygen creates water, so the emissions of the powertrain are entirely green and eco-friendly: water vapors and nothing more. The electric converter located underneath the fuel cell units at the front adapts the voltage level to that of both the electric powertrain and the peak power battery located on the rear axle of the vehicle. The high-voltage battery is fed by brake energy as well as the energy from the fuel cell.

The hydrogen storage tanks are both weight- and space-optimized. They are located on the floor of the vehicle, below the passenger shuttle. The tanks are pressurized to 700 bar and, together, have a storage capacity of 6 kilograms of liquid hydrogen. This mass of fuel ensures a long vehicle range regardless of weather conditions.

The total system output of the hydrogen fuel cell electric powertrain in the upcoming BMW i Hydrogen NEXT reaches 275 kW / 374 PS (368 hp), thus perfectly demonstrating the sheer top performance and viability of the hydrogen-based technology.
