Mercedes-Benz GLA-Class vs BYD Atto 3

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.

Like its interior design, you may find the BYD Atto 3 Extended Range to be a divisive experience. On the one hand, I like how well it handles in the city and the playful design.

The car feels roomy and the boot is a good size but this is not an open-roader. If you plan on doing weekend escapes in this, think again. This is a car that likes the city and will complain if you venture outside of its limits.

I do like the affordable price tag, considering it's an EV, and the features you get but that open-road ride needs improvement.

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 exterior is quite understated and you might not necessarily pick this out as being an EV at first glance. It has a nice-looking profile that immediately identifies it as a medium SUV and it should appeal to owners who want something that looks smart but won't stand out on the road.

There are some cool design elements like the textured chrome panelling on the C-pillar and bonnet, which enhances the BYD badging. The LED strip lighting for the daytime running lights and tail-lights do lean more towards the futuristic vibe that EVs usually showcase.

The interior is where the fun has been had but it's likely to be divisive. The three-tone synthetic leather trims have some pizzazz but not everyone will like the black, white and navy combo.

That said, I like the contrasting red detailing on the piping, stitching and elastic door pocket cords.

The curvy dashboard features a white panel that looks like a flexed muscle (and not in a Magic Mike way!). The air vents remind me of the Echo Base on planet Hoth in Star Wars, which will always be cool to me, but my husband thinks they look like stacked drink coasters.

The rotary door handles are a total vibe and the adjustable ambient lighting manages to tie it all together but while it's great that BYD has had fun in here, not all of it lands for me.

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.

As soon as you slide in, you're pleasantly surprised by how roomy it feels. I have plenty of leg- and headroom in both rows for my 168cm (5'6") height. Which is impressive given the massive panoramic sunroof.

Both front seats are heated and electric with the driver's side sporting a six-way adjustment, while the passenger is only four-way.

However, due to the sports-like seat style, the headrests are fixed which may annoy taller drivers. There is no lumbar support either and, trust me, you'll notice it on a longer trip. Ouch.

Up front, the individual storage is good with an extra deep middle console and a shelf that sits underneath the 'e-shifter'. Plus, there is a glove box and a handy utility tray that houses the wireless charging pad.

The back seat is very comfortable and individual storage is adequate for the odd passenger with two map pockets and four device pockets available.

The drink bottle holders and cupholders (two in each row) are a tad skinny, though, and two regular-sized takeaway coffee cups will overlap at the lid.

Charging options are good throughout with each row getting an USB-A and USB-C port, the front also gets a 12-volt socket.

However, the ports are hidden in the shelf of the middle console and I'd prefer to have the media port up top as it's wired Apple CarPlay and Android Auto.

The 12.8-inch touchscreen multimedia system looks massive on the pared back dashboard and it rotates, allowing you to choose portrait or landscape mode. However, this function is disabled while using Apple CarPlay.

The system is pretty simple to use and the graphics are clear but a lot of functions are buried in sub-menus. Like the heated seat function. I honestly kept forgetting it had them.

I like to drive with the headlights on, as a defensive driving technique, but that dims the screen during the day so much you can't really see it.

The Dirac sound system with eight speakers is sufficient but I noticed the sound quality on my calls was a bit tinny.

The 5.0-inch digital instrument panel's positioning on the steering wheel means you don't miss having a head-up display but the alignment is off by a millimetre or so. Just enough to annoy someone with mild OCD.

The boot space is the highlight for me, though, with its 440L of capacity. You can bump that up to 1340L with the rear seats folded and the rear seats have a 40/60 split-fold.

You'll be making do with a puncture repair kit as there isn't a spare tyre but the powered tailgate was super handy this week on my grocery run.

Curiously, there is no 'frunk' storage, despite there being plenty of room for one.

There's something appealing about BYD's simple and straightforward marketing and purchasing strategy - what you see, is what you get.

There are only two models to choose from, the Standard Range and, our model, the Extended Range. As the name suggests, our model has the longer driving range but there's not that much difference in the specifications between the two outside of that.

One colour - 'Ski White' - is no cost, while 'Parkour Red', 'Surf Blue', 'Boulder Grey' and 'Forest Green' cost $700 extra.

Our model will now cost $51,011 to purchase (before on-road costs), that's a $3630 price hike since the start of the year! Even with the new price, it's more affordable than its nearest rivals with the MG priced at $55,990 and the Leaf e+ at $61,490.

However, you do get a decent number of features for your cash, like heated front seats, electric front seats, a panoramic sunroof, synthetic three-tone leather trims, adjustable ambient lighting, wired Apple CarPlay and Android Auto, and some decent tech (more on that later).

All external lights are LEDs, with headlights having an automatic function and there are two levels of regenerative braking to choose from.

There are some great practical features, too, like a darkened headliner, powered tailgate and 'lock charging port' function (in case you need to leave you car while it's on charge).

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 Atto 3 Extended Range is a full EV with a single motor powered by a 60.48kWh lithium-ion blade battery. It is a front-wheel drive and has a maximum power output of 150kW and 310Nm of torque.

So, it’s not the most powerful on the market but will certainly get you from A to B with ease and you can go from 0-100km/h in just 7.3 seconds.

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.

Let’s talk charging. The Atto 3 has a Type 2 Combo CCS charging port and the on-board DC charger has up to 80kW of capacity.

What does that mean? Well, if you were to plug it in at home on a 7.0kW AC charger, you'd be able to go from flat to a full charge in roughly 10 hours.

Plug it into a 50kW fast charger, and you'd see that time drop to around one hour to get from 10 to 80 per cent charge. However, that capacity means it can't accept the faster 350kW charging speeds on ultra-fast chargers.

The official energy consumption is 16kWh/100km and my on-board figure was 14.7kWh.

It has an official driving range of 480km NEDC (420km WLTP), which is better than some on the market but I got major range anxiety this week!

It feels like it chews through its power. Since it's school holidays, I’ve been doing mostly longer open-road drives and have had to charge it three times already! Over three road trips, I've averaged a little over 200km of driving and saw my percentage go from 100 down to an average of 34 per cent at the end of each trip. 

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.

The driving lets this down for me. It's not as zippy as other EVs I've sampled and can even feel a bit sluggish when you accelerate from a full stop. However, it has enough kick for open-road driving, if you're desperate.

Desperate is the key word, though, because this is a total city-slicker. Around town, it handles itself well in tight streets and corners (that 11m turning circle is a charm) but isn't as confidently placed on the road at higher speeds.

And if you happen to be driving on the open-road on a blustery day, it's no fun at all. It shifts and squirms in the lane, with the cabin noise rising to din levels.

Ride comfort is generally good with suspension that feels cushioned but not floaty around the city. Different story on the open-road!

The controls and e-shifter are all well-placed in the middle console but I'd prefer the start-button to be located somewhere else. I mistook it for the ‘Park’ button a few times, which annoyed me.

The regenerative braking can be adjusted to two levels, low and high. Even on the highest setting, it doesn’t have a big physical presence but there's enough to know it's working.

The Atto 3 earns back a couple of points for being stupidly easy to park. The 360-degree view camera system is super clear and I didn’t have to be too choosy with car spaces either because of its size.

This has a good list of safety features coming as standard, like blind-spot monitoring, lane departure alert, lane keeping aids, rear cross-traffic alert and braking, adaptive cruise control, traffic sign recognition, 360-degree view camera system, as well as front and rear parking sensors.

It has autonomous emergency braking with forward collision warning and features car, pedestrian, cyclist and junction turning assistance. It's operational from 4.0-85km/h (up to 150km/h for car detection).

The Atto 3 was awarded a maximum five-star ANCAP safety rating in 2022 and has seven airbags, including a front centre airbag.

If you have a couple of kids, you’ll like the ISOFIX child seat mounts on the rear outboard seats and three top tethers, but two seats will fit best. 

Curiously, there is evidence of ISOFIX mounts on the front passenger seat which need to be removed for our market, instead of just being 'disabled'.

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.

BYD backtracked from its original warranty launch offer of seven years/unlimited km and the Atto 3 now comes with a six-year/150,000km main warranty.

But the battery has an eight-year/160,000km warranty, which is more in line with the market.

You can choose between two servicing plans – 'Light’ for those who do under 12,000km per year and a ‘Standard’ plan for those who do more. 

Given my open-road and charging experience, I'd say it's a good bet you'll be on the light plan.

On the light plan, services are capped at $189 per year for five-years or up to 60,000km – whichever occurs first.

On the standard plan, which spans eight-years or up to 160,000km, you can expect to pay an average of $299 per service. 

Both plans are fairly affordable but the recommended servicing intervals are every 12 months/20,000 which is a term you often see on a fuel-based car, not an EV.
