Month after month, in the hands of BMW's expert test drivers and engineers, ix5 Hydrogen - the first model of the Munich company that works electrically but with energy supplied by a fuel cell instead of a battery - is growing and becoming more mature and efficient, this in view of a commercial debut that could arrive in 2025.

The iX5 Hydrogen, about a hundred units produced as pre-series, are engaged in a dual activity. On the one hand, there is the promotional and image one, to make the media, large customers (fleets) and other stakeholders of the 'green' mobility transition aware of the advantages of using hydrogen as an energy source.
But BMW's silent and 'very clean' sav (only water vapor comes out of the exhaust) is used day and night on the roads of half the world to fine-tune every detail, including those that have nothing to do with the hydrogen-powered fuel cell propulsion system.
After a contact at the beginning of the year, on the quiet (and not very busy) roads around Antwerp in Belgium, Ansa Motori was able to test the iX5 Hydrogen with eight months of further maturity, and in conditions absolutely close to those that Italian motorists face every day, in urban areas and outside.
BMW's choice of Veneto, and of the roads that branch off into the hinterland of Venice, was not causal: in Mestre, for the moment, there is in fact the only roadside refueling station for hydrogen-powered vehicles, with the hope that the plan approved by the Government for 36 refueling points in the country will materialize without delay.
BMW, on the other hand, is 'very punctual' in proposing - ahead of time with respect to marketing but looking at future possibilities - the advantages and points of technological excellence of the iX5 Hydrogen model.
The car, it should be remembered, is built at the Group's pilot plant at the Fiz in Munich. This is a place where you can breathe innovation and almost artisanal care, an element that serve to constitute the indispensable interface between development and production.
From the very first kilometres, you have the pleasant feeling that the fuel cell system generates a high direct electric current (125 kW, which corresponds to 170 hp) thanks to the chemical reaction between the hydrogen gas and the oxygen in the air that takes place in the fuel cell.
To achieve this uninterrupted operation, it is essential that a constant supply of both elements (H2 and O) is maintained to the fuel cell membrane, an element of fundamental importance for the efficiency of the system.
The gas, which is stored at 700 bar in two high-tech carbon fiber reinforced plastic (CFRP) tanks with a capacity of almost 6 kg, thus arrives at the fuel cell through ultra-resistant pipes, and the immediate reaction between hydrogen and oxygen (with platinum grids supplied by partner Toyota) provides the energy to move the car without hesitation.
Driving the BMW iX5 Hydrogen, you have absolutely no feeling of what is happening in the fuel cell, neither in terms of noise nor olfactory sensations (hydrogen is odourless).
Everything happens automatically so that the fuel cell generates the electricity and sends it, passing through the small 2 kW buffer battery if needed, to the rear motor. It should be noted that the presence of these cylindrical containers does not affect the interior layout or the trunk because they are located in correspondence with the central tunnel and under the rear seats. The fuel cell element, with all the electronic control and management equipment, takes the place of the ICE engine in the vanor engine, while the 401 hp electric motor is located at the rear.
Driving, except for the fact that an indication of the remaining range is clearly visible on the dashboard, does not differ from that of another battery-powered BMW 'i'. During deceleration and braking, the fifth-generation eDrive electric motor also acts as a generator, returning energy to a power battery.
The driving sensations and the comfort, especially acoustic, are also perfectly comparable to those of an electric car.
iX5 Hydrogen moves with absolute smoothness of ride and offers scorching acceleration since it makes the 0-100 sprint in less than 6 seconds the brake pedal with the one-pedal setting with maximum regenerative recovery: The top speed is self-limited to 180 km/h, more sufficient for normal driving habits. With 6 kg of hydrogen, the BMW iX5 Hydrogen offers a range of 504 km in the WLTP cycle, compared to a WLTP-approved fuel consumption of 1.19 kg/100 km.
