The Japanese subsidiary of BMW AG announced an FCV (fuel-cell vehicle) concept Sept 26, 2016.

The concept was made by equipping the body of the "5 Series" sedan with a fuel-cell stack, hydrogen tank, etc. BMW is developing a fuel-cell stack, which is a main component, in collaboration with Toyota Motor Corp. And it plans to release an FCV with a price equivalent to that of a gasoline vehicle in 2020.

"We will cut the costs of the FCV through the joint development with Toyota and release it in about 2020," said Matthias Klietz, who is an executive officer of BMW and responsible for the development of powertrain. "We will realize a cost only 10% higher than the cost of a gasoline vehicle, which our customers wish."

The key to the cost reduction is a fuel-cell stack, which consists of fuel cells.

"We will improve the energy density and productivity of cells," Klietz said. "We will also cut the costs of other components."

The concept is based on the "5 Series Gran Turismo," which was developed by combining a sedan and an SUV (sport-utility vehicle). It has the same fuel-cell stack as the "Mirai" FCV, which Toyota released at the end of 2014.

The Mirai has its fuel-cell stack in its central area and is a front-wheel-drive vehicle. On the other hand, the fuel-cell stack of the concept is located in its engine compartment, and its rear wheels are driven by a motor placed in the rear area.

The pressure of hydrogen gas in the hydrogen tank is 70MPa. The concept has one tank. The maximum speed of the vehicle is 180km/h (approx 112mph). The output of the driving motor is 150kW or higher. It can travel 450km per charge.
