BMW iX5 Hydrogen: trip with fuel consumption economy city, sub-urban mpg kg/100 km, fuel cell, fcev

BMW iX5 Hydrogen is an electric car with fuel cell stack which produces electricity from hydrogen and oxygen. Onboard tanks can store up to ~6 kg of highly compressed hydrogen (H2). The fuel cell stack power: 125 kW (170 HP), the system power (thanks to additional battery): 295 kW (401 HP). WLTP consumption: 1.19 kg/100 km, WLTP range: 504 km. I checked BMW iX5 Hydrogen FCEV on a trip with city driving, country roads (sub-urban), also on highway. Finally I achieved ~1.1 kg/100 km (1.77 kg/100 mi, 56.5 mi/kg, 57.1 MPGe) on ~29.3 km (18.2 mi) distance. See how this system works and what kind of economy is possible.
