BMW iX5 Hydrogen: A polished drive that promises convenience

Wrapping its technological sophistication in fastidiously familiar form, the iX5 Hydrogen offers a wholly convincing alternative in the realm of EVs - at least to those who can utilise it.

Alongside the colour blue, that's a letter we've come to associate with BMW's range of electric vehicles for a while now. And by a while, we mean more than nine years - since the covers were first pulled off a curious-looking hatch called the BMW i3.

Gradually progressing from a forward-facing product that arguably skewed more 'niche' than 'mass market', however, BMW has pursued a vision of normalcy more recently: In which electric vehicles (EVs) are everyday rather than specialised-cars.

In 2022 alone, the Group (including MINI) sold more than 215,000 of them. It says a lot, then, that it hasn't just tacked 'Hydrogen' to the back of the name of its latest X5-resembling fuel cell electric vehicle (FCEV). Instead, in naming it the BMW iX5 Hydrogen, the firm is making it clear: It wants to associate hydrogen power with its growing push for electromobility. 
First glance: Familiar face

Built indeed with the BMW X5 as its base, the closest parallel one could draw to the visual 'i'-fication of the iX5 Hydrogen is perhaps how the X3 was aesthetically transformed into the iX3. Here, however, it's done with a freer-flowing hand. While its blue-accented front and rear aprons and kidney grille surrounds should not be unfamiliar to most, more prominent is the way the car announces its unique powertrain, with triangular patterns flowing over its bonnet and onto its sides. Of course, hardest to ignore are the words 'BMW i Hydrogen Fuel Cell' printed across the doors and tailgate.

Since development of the car started four years ago, an interesting thing to note is that the iX5 Hydrogen borrows from the pre-facelifted rather than recently refreshed X5. Nonetheless, it does get its own cooler shade of blue, and unique wheel inserts you won't find on other BMW i cars.

Yet another noteworthy detail is that despite eliminating the ICE X5's twin tailpipes, the iX5 Hydrogen does actually emit water vapour. This is channelled underneath the vehicle's chassis, rather than towards the rear.

Taking it in(side): Impressively normal 

Ostensibly choosing to ease drivers into the (relatively) new technology instead of overwhelming them with otherworldly gadgetry, the iX5 Hydrogen is also far from foreign when you climb in. In fact, one might argue that the space feels more familiar than the ostentatious tech-flex-on-wheels that is the BMW iX.

Without a Curved Display, the car's digital instrument cluster and central infotainment touchscreen are once more distinct entities, and run OS 7 rather than OS 8. Likewise, a conventional 'stick' lever (blue-accented, of course) rises out of the centre console. 

Nonetheless, the iX5 Hydrogen does remind occupants of its individuality again with its model-specific lettering imprinted onto the dashboard, and seatbelts outlined in blue.

But don't mistake familiarity for a lack of technological sophistication - for the iX5 Hydrogen gets a completely new floor assembly in order to accommodate its unique drivetrain.

With its two hydrogen tanks neatly stored underneath the centre tunnel and rear seat unit, no compromises in space are made at the rear, allowing the car to offer as much head and legroom to second row passengers as its combustion-engined brethren.

Since the iX5 Hydrogen is packaged similarly to the plug-in hybrid X5 xDrive45e, its boot capacity is still quite sizable, although it also doesn't have third-row seating capability. 

On the move: As EVs do

BMW says the car is similar in weight to a similarly-sized PHEV - and less than a BEV. Therein lies the case for FCEVs, BMW says - larger models shave some weight off without the need to shove in massive batteries.

With 710Nm of instant torque, the iX5 Hydrogen will hit 100km/h from rest in under six seconds, before going on to reach a maximum of 185km/h.

Consequently, the driving experience is just as what you get in the firm's other EVs. The iX5 Hydrogen is smooth and silent; refined and quite cosseting (no doubt aided by its air suspension); perhaps, even slightly ballistic if your right foot wills. These qualities are rounded off with nicely-weighted brakes, whose regenerative strength can be intuitively toggled with paddle-shifters.

Additionally, while fundamentally still quite a large vehicle, the car feels as responsive to a driver's inputs as can get in the luxury SUV segment it occupies.

Of course, efficiency in such a vehicle is measured in a different manner to L/km or km/kWh. And so, with its instrument cluster headlined once more by 'Hydrogen Fuel Cell', the little figure just right-of-centre states 'kgH2/100km'. The 'largely familiar, slightly different' trend should be clear by now.

In just three to four minutes, the iX5 Hydrogen's two tanks are capable of getting refilled with 6kg of hydrogen at 700-bar - sufficient for a rated range of around 500km. Against the 20-minute downtimes for even BEVs with the most powerful battery architectures right now, that's lightning-quick.

But caveats naturally remain.

Another path towards normalcy - but only partially realised for now

Towards the adoption and construction of hydrogen infrastructure, commitment remains quite patchy across different territories. 

On our media drive, we were told a staff member managed to drive from Munich to Antwerp (about 770-ish km if we're talking the FIZ to the Havenhuis) with the iX5 Hydrogen within a day - which is highly possible, since there are nearly 100 hydrogen refilling stations across Germany. Where we are in sunny Singapore, you'll have to cross the border to find our nearest station; Malaysia has one.

It will come as no surprise too, then, that the car is not coming to us. While BMW's electromobility case for (larger) hydrogen-powered vehicles sounds convincing, the reality of today cannot be changed. 

It doesn't matter how far the iX5 Hydrogen will go on a single tank or how quickly that tank is refilled - if it cannot even be refilled. 

Make no mistake - the iX5 Hydrogen is as polished, fully-formed, and delightfully unassuming as a hydrogen vehicle can possibly be. You walk away from the car, not blown away by the staggering volume of tech it tries to show off, but won over by the silent finesse with which it mirrors all of an EV's qualities with the promise of convenience. 

For now, however, we'll just have to wait for that promise to be fulfilled.
