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.

BYD hasn’t made dramatic changes to the Atto 3 for 2024, but has it done enough to lure in more buyers? 

The additional equipment, namely the larger infotainment screen and new tyres, will certainly help make the Atto 3 more appealing. And the technology behind EVs is more understood by the average motorists, so the barriers to making the switch to electrification are dropping.

But the single biggest factor is likely to be the price. At a time when inflation (and other reasons) is driving the cost of new vehicles up, having your updated model go in the wrong direction will only help make potential buyers take notice.

Especially when you consider Toyota’s closest rival to the Atto 3, the bZ4X, starts at $66,000, while the Tesla Model Y is priced from $55,900, making both significantly more expensive propositions. Heck, the cheapest Toyota RAV4 hybrid model starts at $42,260, only marginally cheaper than the Atto 3 Standard Range.

So, if BYD can make its value argument strongly it will help lure more new buyers to take the plunge into the world of EVs.

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.

In a couple of words, not really. At least when it comes to the exterior design.

In fact, the biggest design change for 2024 is actually the colour of our test car, the new Cosmos Black. Apart from that, the rest of the Atto 3 is unchanged visually, which is becoming something of a trademark for EVs, at least from newer brands like BYD and Tesla. 

Instead of worrying about adding a new grille, different headlights or an alternative alloy wheel design, brands like BYD are focusing on updating batteries, the technology and other software enhancements to keep their models fresh.

The only exterior change is at the rear, where the previous 'Build Your Dreams' lettering has been replaced by a simple 'BYD' badge.

As for the interior design, kudos to BYD for not following Tesla down the cost-saving-disguised-as-minimalist-design path, but personally the design aesthetic and the variety of colours and trims used aren’t to my taste, but I can see why others may love it. The ‘guitar string’ door pockets are likely a particularly polarsing design choice.

BYD has added a new interior option, with a black/blue trim for the examples finished with grey and black exteriors, while white and blue painted cars get a blue/grey interior.

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 Atto 3 remains classified as a ‘Medium SUV’ but blurs the line between mid-size and small in terms of dimensions, especially inside. It’s not in the same size game as the Toyota RAV4 or Mitsubishi Outlander, but is close in size to the likes of the Honda ZR-V and Mazda CX-5.

While there’s a few key practical storage spaces, there aren’t as many as some newer rivals, which does suggest the Atto 3 design is starting to date or just wasn’t well thought-out enough in the first place; such as putting all the switchgear in the centre console rather than on the dashboard.

This was probably done, at least in part, to accommodate the rotating touchscreen, which seems like a poor design and practicality choice to me. Especially the new one, which at 15.8-inches when rotated to the portrait mode it starts to interfere with your vision and the layout is more user-friendly in landscape mode - both when using the native multimedia system or your smartphone connection.

Space is respectable in the back seats, and there’s both a USB-A and USB-C port for charging devices. While out the back the boot measures 440 litres, which is a respectable amount of space for an SUV this size, but there’s only a tyre repair kit instead of a spare wheel.

As we just mentioned, price has been a critical tool for carmakers looking to keep demand for EVs rolling along as the early adopters fade, and BYD is not immune from this. Earlier in 2024 the Atto 3 Extended Range, the model we’re testing here, started at $50,011 before on-road costs. Then in April 2024, BYD announced a drive-away deal for $45,990 for pre-registered demos. 

Now this updated model is priced from $47,499 (plus on-road costs), which is a jump up from the sale price, but is more than $3500 cheaper than the Atto 3 was at the start of 2024. Meanwhile, the Standard model is priced from $44,990 (plus on-road costs), which is also a saving of more than $3000 on the previous model.

The key difference between the Standard and Extended Range models are the batteries, so the specification is similar. Both variants are equipped with LED headlights, power tailgate, synthetic leather upholstery, power-adjustable front seats, 5.0-inch digital instrument panel and in-built satellite navigation.

One of the big ticket item changes for 2024 is the upgraded 15.8-inch multimedia touchscreen, which comes with BYD’s signature trick - rotating between portrait and landscape modes. This is upsized from 12.8-inch in the old model. Wireless Apple CarPlay and Android Auto are now standard too.

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.

As with the design there isn’t much to say about what’s powering the Atto 3 because it’s the same as the 2023 model. Both the Standard and Extended Range use the same front-mounted electric motor, which makes 150kW/310Nm and drives the front wheels through a single speed transmission.  

With 0-100km/h times of 7.9 seconds and 7.3 seconds respectively for the Standard and Extended Range, the Atto 3 won’t shove you back in your seat, but it has adequate performance for a mid-size SUV. 

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.

The Standard Range has a rated driving range of 345km (WLTP) from a 49.92kWh ‘Blade’ lithium-iron phosphate (LFP) battery while the Extended Range’s bigger 60.48kWh unit increases that to 420km.

Charging is capped at 70kW (DC) for the Standard and 80kW (DC) for the Extended. 

One of the major hurdles for EV brands is convincing people that they won’t run out of charge every day. At 420km the Extended Range Atto 3 will get most people through multiple days of commuting, so even with public charging you shouldn’t worry about range anxiety. 

Those drivers with commutes longer than 420km per day should be looking at something other than an electric car (and probably a job closer to home).

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.

Driving the updated Atto 3 feels… fine. Nothing special or class-leading, but within the expectations buyers should look for in a mid-size SUV. Which is meant as a compliment to BYD, as it is still a relatively new brand in this very competitive market and there are certainly some noticeably worse rivals in this same segment. 

The Atto 3 may not be the most comfortable, most powerful or most dynamic mid-size SUV, but it’s a perfectly nice thing to drive and it will get you from Point A to Point B quietly and smoothly.

Another of the major changes for 2024 is BYD’s decision to ditch the fantastically named, but not very good Atlas Batman tyres, replacing them with Continental rubber. The Atlas tyres were a major drawback on the old model, lacking grip and detracting from the driving experience, with the new ‘Contis’ solving those problems. 

In terms of safety, both Atto 3 variants get a comprehensive list of both passive and active safety features, enough to score a five-star ANCAP rating.

There’s airbag coverage for all occupants, 360-degree parking cameras, adaptive cruise control, autonomous emergency braking, forward and rear collision warning, blind spot detection, lane departure warning, lane keeping assist, rear cross-traffic alert, rear cross-traffic brake and door open warning.

Most of these systems behaved themselves during our testing, although the forward collision warning did seem overly sensitive at times, and sounded alarms over potential accidents that simply weren’t a problem. Still, compared to some modern brands, the BYD systems performed well.

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 offers a six-year/150,000km warrant for the vehicle, with eight years/160,000km coverage for the batteries.

Service intervals are every 12 months of 20,000km and while a minor service is only $165, every second visit is more expensive, ranging from $498 to more than $600. There may be less oily bits under the bonnet but there’s still a cost to owning an electric car.
