Mercedes-Benz GLA-Class vs Citroen C5 Aircross

What's the difference?

With Mercedes-Benz’s vast number of SUVs, there is room for an urban luxury crossover niche, and the GLA delivers in spades.

Indeed, in 250 4Matic guise, it is that rare thing – a high-riding hatch with dynamics to shame most dedicated pocket-rockets. It really is a hoot if you find the right road, regardless of weather conditions. The Benz has towering talent.

However, even without desirable options like adaptive dampers and a full suite of driver-assist safety technology, the GLA is expensive, does not quite carry off the price tag from an interior quality point of view, and struggles to maintain the degree of comfort and refinement expected from a Mercedes – with or without the $3K necessary to score adaptive dampers.

Still, especially because of the way the GLA looks, goes, stops and steers, if you can afford it, you’ll be rewarded. There’s never been a more rounded GLA.

So, what did my family think about the Citroen C5 Aircross Sport?

I love how it looks and its updated safety list. It’s fairly spacious inside and has a great boot space but it’s lacking a lot of family-orientated practicality in the back seat. The lack of individual storage and amenities is noticeable when you have a kid or two but even as an adult, not having a cupholder for your coffee/drink on a trip feels odd.

The multimedia system and reversing camera need to be improved, too. Overall, it will suit a small family which is out of the baby stage but can’t yet justify upgrading to a larger SUV. It gets a 6.5/10 from my family. 

Looking like a mini-me GLC, today's GLA trades some of its predecessor’s edgier design elements like the slammed roof and exaggerated broad-shouldered stance for a more amorphous if elegant appearance. Even with the cliché plastic cladding around the squared-off wheel arches, it’s still a looker.

The net result is arguably the most attractive of all the MFA2 A-Class offshoots. It sits well within the Mercedes hierarchy of SUVs, bringing a swoopy coupe-like silhouette compared to the ultra-upright GLB.

Along with being 30mm wider, it’s also visibly taller than before, with a handy 213mm of ground clearance compared to just 157mm last time around. And the wheelbase has been stretched to the benefit of rear-passenger room – a bugbear of the old GLA. That's progress.

The facelifted model sees a sportier front with the grille redesigned to highlight the double chevron badge.

The bonnet curves around the badge, as do the two long LED strip lights that connect the headlights. The bonnet also sports new divots that give it a gruffer edge.

The wide profile at the rear and new three-pronged tail-lights create some interest.

The black plastic moulding that runs along the base of the car could look unfashionable on a lighter colour but on our blue paintwork, it looks good. As does the contrasting black roof!

The interior trims are finished in a combination of synthetic and Nappa leather but boast a two-tone colour which might not land with everyone. Particularly given the navy portions seem to be glittery in certain lights.

Sitting at 1859mm wide, 1695mm high and just 4500mm long, the overall exterior design is sporty but cute. It should appeal to those who want a nice-but-not-loud-looking car and something that is easy to park.

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.

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. 

There is only one model for the C5 Aircross Sport and it will set you back $54,990, before on-road costs.

That prices it as the most expensive compared to its rivals with the Mazda CX-5 GT SP ($51,810) coming in closest but the Nissan X-Trail ST-L ($46,790) and the Kia Sportage SX+ ($41,850) are even more affordable.

The only included paint colours are 'Polar White' and 'Nera Black'. Our model’s 'Eclipse Blue' will add on $690.

However, the C5’s price tag doesn’t feel too cheeky because of the feature-heavy specification, including heated front seats, electric driver’s seat with massage function, a panoramic sunroof and a mix of premium Nappa leather and synthetic leather interior trim.

You also get a powered tailgate, rear privacy glass tinting, full LED lights on the exterior, individually sliding seats on the back row and black 19-inch alloy wheels.

The technology has been upgraded with the dashboard being headlined by a 10-inch touchscreen multimedia system and a 12.3-inch digital instrument panel.

Built-in satellite navigation, as well as wired Apple CarPlay and Android Auto are also included as standard equipment.

On top of that, the safety list has been significantly improved, but more on that later. 

Mounted transversely, Mercedes’ M260 1991cc 2.0-litre four-cylinder petrol engine features a twin-cam, 16-valve design, a twin-scroll turbocharger and variable-valve timing, to help deliver 165kW of power at 5500rpm and 350Nm of torque at a low 1800rpm. With an impressive 97.2kW per tonne, it can hit 100km/h in 6.7 seconds, on the way to a 240km/h top speed.

All four wheels are driven by an eight-speed dual-clutch transmission (DCT), though most of the torque at lower speeds or during reduced throttle loads is delivered to the front wheels until extra traction is required out back. The gearbox is one of the very best of its type we’ve experienced – seamless, strong and largely lag-free.

The C5 Aircross Sport has a 1.6-litre, four-cylinder turbo-petrol engine with a maximum power output of 133kW and 250Nm of torque. It’s not super grunty but there’s plenty here to keep you up to speed on the open road.

It is a front-wheel drive and has an eight-speed auto transmission but the gear changes can feel a bit jerky at lower speeds.

Weighing in at 1668kg (kerb), and with a bluff nose and high ground clearance also not helping, we didn’t expect great fuel economy, particularly given how hard and fast the GLA 250’s performance bandwidth is. It’s tempting to just blast your way from point A to point B.

However, at the pump we averaged 9.8 litres per 100km, which isn’t too bad at all considering the available muscle. The official figure is 7.5L/100km, for a carbon dioxide emissions rating of 170 grams per kilometre. With a 51-litre fuel tank, the theoretical range is around 680km.

Note that the GLA 250 requires 95 RON premium unleaded petrol as a minimum.

Ah, this is where it earns back some points!

I was very impressed by the efficiency of this because the official combined cycle fuel figure is 5.7L/100km and my real-world usage came to 6.2L! That’s fantastic for this sized SUV and for a turbo.

With a fuel tank of 53L and based on the combined fuel figure, you should be able to get a driving range of around 930km, which is good for those families who like to do road trips.

A soaring 2.0-litre turbo engine application, this is a slick, stirring and robust performer that can also do efficiency as effortlessly as launch the GLA 250 4Matic towards the horizon. Let’s not mince our words. This is a fast and fiery mover.

Three drive modes – Eco, Comfort and Sport – provide a wide spectrum of acceleration and throttle responses, and all deliver precisely what you’d expect. Eco’s fine for pottering around town smoothly and serenely; Sport morphs into a searing and seamless speed demon; and the default Comfort sits somewhere in the middle as the best of both worlds. There really is no faulting Mercedes’ M260 masterpiece.

The DCT also happens to be one of the better dual clutch autos, avoiding the lag and clunkiness pitfalls usually associated with this sort of gearbox. It’s even comparatively smooth off the line on hills. Ours came with the optional handy set of manual-mode paddle shifters, adding a welcome level of interactivity autos tend to overlook. Too bad Mercedes persists with that fiddly column lever that is forever prone to knocking the car out of drive. Even after 15 years, it's still so annoying.

What all this means for the urban driver is strong acceleration for flitting in and out of traffic gaps, as well as incredibly instantaneous point-to-point responses for commanding manoeuvrability, thanks to ultra-eager steering and assisted by outstanding brakes.

With struts up front and a multi-link rear end as standard, the GLA 250’s chassis, too, is a transformative for what is essentially a high-riding hatchback – but only if your pockets are deep enough.

Fitted with that near-$3K AMG Exclusive Package that includes adaptive dampers, our Benz displayed a definite hot-hatch attitude that really would make it the darling of Golf GTI owners who’ve outgrown their rides but not their girl/boyracer desires. Superb handling and hunkered-down roadholding really do make this the driver’s premium compact crossover. You can pretty much point and shoot this Merc as you might a Golf R, and likewise in most weather conditions thanks to all that reassuring tenacious grip.

Plus, if you’re put off by the hard ride in Sport, the Individual mode allows the driver to engage the soft damper mode while the engine and steering retain the hardcore settings. It’s a win-win situation – as long as you can stretch to that AMG Exclusive pack. We strongly recommend it, given the balance between ultimate high-speed control and comfort.

However, while this is all good news for rural and country folk seeking hot crossover fun, back around town, poor urban road conditions can reveal a flaw in the chassis’ ability to properly smother bumps and ruts. It’s the small frequency stuff that seems to transmit through, never really settling down.

The result is a jittery ride, that may somewhat undermine the GLA’s upmarket sheen. There’s also a fair degree of road noise coming through. Perhaps sticking with the 19-inch alloys instead of those lovely 20-inch rims is the solution here.

Despite its city-friendly size, the C5 Aircross Sport is just as happy cruising on the open-road as it is in an urban environment.

The ride is smooth enough once you get up to a steady speed but the suspension can feel harsh on a bumpy road.

Also, the auto stop-start function can make it feel sluggish to respond, so I disabled this on most trips.

There is plenty of power so you'll feel confident overtaking or getting up to speed on the open road. However, you have to be a little more aggressive with the accelerator when you’re hitting hills.

The steering can, at times, feel vague when you’re at lower speeds but is otherwise responsive.

The cabin space is quiet and nice to be in on the highway and you’ll be able to chat with your passengers with ease.

What I like most about this though is the visibility – the windows are large and I feel like I have a clear view most of the time, which isn’t always the case in an SUV.

Parking this is a cinch with entry to tight car parks helped by a 10.7m turning circle!

However, the 180-degree view camera isn’t great and near hopeless at night time. A clearer image would be welcome but front and rear parking sensors ease the annoyance.

The updated safety list is most welcomed, especially on a family SUV.

The C5 Aircross Sport has the following as standard - daytime running lights, forward collision alert, lane keeping aid, lane departure alert, blind-spot monitoring, rear cross-traffic alert, intelligent seat belt reminders, traffic sign recognition, 180-degree view reversing camera, front and rear parking sensors and adaptive cruise control with stop and go function.

Special mention for the new fatigue detection alert. When it triggers it doesn’t stop sounding until both of the driver's hands are detected on the steering wheel.

The autonomous emergency braking with car, pedestrian and cyclist detection is operational from 10 – 80km/h (5.0 -140km/h for car detection), however the pedestrian and cyclist functions are only detectable in the day time. It’s usual to see it operational at night, as well.

Despite the new safety items, it still only has six airbags, which includes curtain airbags covering both rows but that’s pretty low for a family car nowadays.  

It was awarded four from a maximum five-star ANCAP safety rating back in 2019 but didn’t have all of the new items at the time of testing.  

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $550 for the first year, $750 for the second year and $1250 for the third year, totalling $2550. Alternatively, buyers can also choose a Service Plan, starting at $2050 for the first three years (saving $500 from the normal capped-price service plan), $2950 for four years and $3500 for five years.

The on-going costs are super-reasonable on the C5 Aircross Sport, with a five-year/unlimited km warranty included.

You can also choose to pre-purchase a three- or five-year capped-priced servicing plan, both significantly cheaper than the pay-as-you-go option. 

On the three-year plan, services are $1100 or an annual average of $366.

It’s a flat $2000 for the five-year plan, (averaging just $400 per service), which is very competitive for the class.

Servicing intervals are every 12 months or 15,000km, whichever occurs first.

The Aircross also comes with a five-year roadside assistance plan that is offered through Digicall Assist, for added peace-of-mind.
