Citroen C5 Aircross VS Mercedes-Benz GLA-Class

The interior is spacious for a medium SUV but the back seat knocks off some points for family practicality. So, let’s start in the back.

Despite there being plenty of headspace for my 168cm (5’6’’) height, the legroom is cosy behind my driving position.

Meaning a 0-4 rearward facing child seat will encroach on front passenger space. It’s probably best suited to a family which is out of the baby stages but it was cumbersome fitting my big harnessed-booster seat in there, too.

It has ISOFIX child seat mounts on the outboard rear seats and three top tethers but two seats will fit best. The floor is flat, which offers far more comfort for a middle seat passenger and I love how the seats can be individually shifted.

The amenities and storage in this row are sparse. You get directional air vents, reading lights, netted map pockets and shallow storage bins in the doors.

Siblings may squabble over the single USB-A port on a long road trip but more than that, there are no cupholders or drink bottle holders back there or even a centre armrest.

That said, the 182mm ground clearance made it an easy car for my six-year-old to get in and out of; plus, the stadium-like seating and wide windows meant he had an awesome view this week.

Now for the front. It has ample amenities, storage and tech. You get plenty of head- and legroom, plus with the panoramic sunroof the cabin manages to feel airy, too.

Individual storage is great with an extra deep middle console, glove box, two cupholders, bins in each door and two very handy utility trays situated near the toggle-type shifter.

Charging options are much better up front, too, and you can choose between a wireless charging pad, two USB-A ports and a 12-volt socket to charge your device.

It's super easy to connect to the wired Apple CarPlay and there’s wired Android Auto for those users.

The built-in satellite navigation is straightforward but that’s where the simplicity ends. I did not find the multimedia system or the digital instrument panel to be terribly intuitive to use and the touchscreen controls can be laggy.

I’m sure you could get used to it over time but I felt flustered.

For this size SUV, the boot space is great at 580L with all seats in use but you can bump it up to 1630L if you fold the back row.

The floor can be adjusted to make a level load space or dropped to give you greater depth for bulkier items and there is a temporary spare tyre underneath the floor.

There are luggage tie-down anchors, a cargo blind and I always like having a powered tailgate. 

Compared to before, the 2021 GLA is some 122mm taller, so ushers in a higher hip point for loftier seating – reducing that jumped-up hatch feel. Headroom improves obviously, as does rear legroom, a corollary of a 30mm wheelbase stretch (to 2729mm).

Wide apertures also make entry into and out of the German-built GLA child's play, though the solid heft of their doors is serious business at this end of the segment, very satisfyingly Teutonic and totally on-brand. This is something you won’t enjoy in a Subaru XV.

Then you s-c-r-a-p-e the underside of the front doors on the pavement literally every time you swing it to get out, and wonder whether Mercedes engineers have ever been to Australia. This fail drove us spare. Heaven help the GLAs in towns and cities with bluestone sidewalks. Maybe all that extra AMG packaging is the culprit.

Still, most of the other basics are spot-on and can’t really be faulted; cosy yet spacious for four adults – especially up front, ample vision, an excellent driving position aided by heaps of seat and steering wheel adjustability, cosseting front sports buckets that you just sink into, torrents of ventilation from those delectable turbine vents and stacks of storage. Collectively they make the GLA a welcoming, opulent place to travel in. Only the hapless fifth occupant squished between the outboard rear-seat passengers might think otherwise. But nobody buys this Benz for carting people around. That's the GLB's job.

Several years ago, Daimler poached a senior Audi designer and since then Mercedes’ dashboards have morphed into a multi-coloured multimedia diorama of touchscreen technology that threatens to completely take over the universe. Choose the right combination of colours and lighting and it's like your very own White Night on wheels. Starting with 2018’s A-Class, the striking, spangly MBUX system that underpins all this has come to be widely admired and imitated. For aesthetics anyway, with its vivid hues, panoramic displays and simple, tiled applications, it’s been a real trip.

Anyway, back to reality. From a tactility and functionality point of view, there’s still work to be done.

Access to the multimedia (including our GLA's banging optional audio system) and car settings areas is possible via a mildly fiddly finger-pad arrangement down forward in the centre console, or smaller yet much more annoying thumb sensor tabs on the wheel spokes. These are not easy to modulate on the move. Additionally, their menus can be confusing to navigate through and sometimes counterintuitive in operation. Mercedes obviously realises this as a quick-guide pamphlet is provided on old-fashioned cardboard paper. How quaint.

Eventually all areas can be mastered over time, but the functionality is complicated and may overwhelm the not-so-tech savvy. Additionally, the ‘Hey, Mercedes!’ voice control is impressive for getting MBUX to perform basic multimedia and vehicle settings-related changes, but it too-often erratic, unreliable and ultimately frustrating for more complicated commands. Perhaps elocution lessons on behalf of the operator may help.

But not as much as the profound disappointment we endure from the cheapness of some of the materials, the wincing cellophane-like sounds when pressing on some of the surfaces such as the door cards, or that emanate after a particularly bumpy section of bad roads. Sheeny reflections and hard textures in a car optioned with extras that total up to nearly $82,500 just don’t cut it.  

At least in this latest-gen GLA, the rear seat area seems much improved over the previous models, with more space, comfy and supportive seating (remember ours featured the $607 sliding function that ought to be standard) and a reclining backrest. All amenities are present, with deep pockets, fresh air from twin vent outlets, reading lights and thoughtfully placed armrests – but, again, the latter’s extendable cupholders feel brittle and cheap.

Further back, the 435-litre cargo area is sufficiently sized and practical for smaller family use (at last), aided by a 40/20/40 backrest fold and that slide-able cushion to extend capacity further. There is no spare wheel, but a tyre inflation kit is fitted in lieu.

Overall, then, better than before, with that fundamental rock-solid heft, luxurious aura and alluring premium-car aroma. The dazzling MBUX screen-related visuals, too, are endlessly entertaining to explore when the vehicle is not moving, but the GLA’s cabin is still not quite up to Mercedes’ reputation for exacting over-engineered excellence.

Or even to the standards of some mainstream alternatives.
