Mercedes-Benz GLA-Class vs Tesla Model Y

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.

The Model Y Long Range is the pick of the line-up thanks mainly to its ability to travel further on a full charge, but also the price is excellent. The styling is starting to date, especially compared to fresher rivals with intriguing designs. But the advantage to Tesla is its battery tech and the constant over-the-air updates which will continue to enhance this product long after you've bought it.

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 Model Y is a mid-sized SUV, about 4.75 metres long and has an aerodynamic wedge shape similar to the one Toyota’s early Prius had, but with a smooth and flat styling Tesla twist.

The clean and featureless look made the Model Y appear futuristic and modern two years ago but now, with the arrival of other mid-sized electric rivals and their intriguing and attractive designs, the Tesla is starting to appear dated. 

There is a styling update coming to the Model Y, but it won’t be a completely new car, just a few tweaks to keep it looking current. But it won’t do much. I think the time is up on this design.

The cabin embraces minimalism with plenty of clean and smooth horizontal surfaces devoid of buttons or dials. Only the large central screen and the steering wheel exist on the dashboard and in my eyes compared to rival offerings the Model Y’s interior has quickly gone from cool to devoid of personality.

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.

Electric SUVs have moved practicality to a level combustion-engine equivalents can’t compete with thanks to their front and back boots and (no transmission tunnel) flat floors maximising people and storage space. 

The Model Y is practical with a 117L front boot and a rear boot with 854L litres of cargo capacity, while the cabin has large door pockets, wireless phone charging and two cupholders up front and in the second row.

The Model Y comes as a five-seater only, but leg- and headroom in the second row is excellent and even at 189cm tall I can sit behind my driving position. 

Back seat passengers also have directional air vents and two USB ports for charging.

Cabin practicality could be better, though. The large centre console is unnecessary as it’s not covering a transmission and driveshaft. We’re seeing other brands such as Kia make use of this area as a storage space perfect for even large bags.

Locking and unlocking the Model Y is done with a key card that needs to be swiped against a sensor in the B-pillar. This worked sporadically for me and I felt like the action could scratch the pillar’s surface.

There’s a phone app which can also lock and unlock the Model Y. We downloaded it and found the functions useful, from seeing how much charge is in the battery, to opening the boot, tracking the location of the car and turning the climate control on to cool or heat the cabin before driving. 

Only the weather changes more than Tesla’s pricing, but the latest adjustment to the Model Y Long Range price had it listing for $72,900. That could easily change again so it might be best to check back at CarsGuide or Tesla’s website for any updates.

At almost $73K the Long Range sits in the middle of the Model Y line-up, above the $64K entry grade and below the $83K Performance.

The standard features list for on the Model Y Long Range is decent and includes LED headlights and 19-inch alloy wheels, there’s the fixed glass roof, synthetic leather upholstery, the 15-inch central touchscreen, power adjustable and heated front seats, a 13-speaker stereo, sat nav, wireless phone charging, dual-zone climate control with direction air-vents in the second row and a power tailgate.

Also standard is Tesla’s so-called 'Autopilot' which is an advanced form of adaptive cruise control which combines braking and steering.  

Anything missing? A sunshade for the glass roof would be good. You can buy aftermarket ones but really it should be built-in. There’s no rear climate control, either, nor ventilated seats.

But the one item that’s not here and should be is a head-up display because the location of the speedo on the central display isn't ideal for keeping your eyes forward and on the road.

So, the price is good but the features list could do with a boost. Really, though, the reason for picking the Long Range grade is because it can travel further on a full charge than any other Model Y. You can skip ahead to the Efficiency section if you’re busting to find out what the range is.  

As for rivals, there are way more now than there were when the Model Y first came to Australia a couple years ago. Back then it was really just the Hyundai Ioniq 5.

Now there’s the Kia EV6 and soon to arrive EV5, the Mustang Mach-E, the Subaru Solterra and its Toyota bZ4X twin, while the Polstar 4 is coming, 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.

The Model Y Long Range is all-wheel drive thanks to a motor powering the front wheels and another turning the rear ones.

Together the motors have a combined output of 378kW and 493Nm which is an enormous amount of power and torque for a family SUV like this and that means the 0-100km/h time is also a pretty quick 5.0 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.

The Model Y Long Range’s name suggests it's the version for those looking for the maximum distance they can travel on a full charge and it is the smart choice in the line-up. That said, the extra range isn’t all that much more than the other grades.

Tesla says the Long Range with its battery fully charged can travel up to 533km and has a combined cycle energy efficiency of 16.9kWh per 100km (WLPT).

A range of 533km is impressive but only 78km more than the entry-grade Model Y and just 19km more than the top-of-the-line Performance.

How accurate are Tesla fuel efficiency figures? Well, my own testing over a combination of all types of driving saw the trip computer report an average of 16.8kWh/100km.

Tesla says one of its 250kW Superchargers can add up to 275km of range in 15 minutes.

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.

CarsGuide hasn't been alone in criticising the Model Y’s overly firm suspension with potholes and bumps seeming to unsettle the vehicle easily.

But Tesla says it's updated the suspension to a more ‘comfortable’ tune and we had a chance to test it.

So, is it more comfortable now? Yes, but it could be better. There appears to be softer absorption in the suspension but anything other than small bumps are still prominent.

Body control remains a bit jelly-like in that there’s too much jiggling and leaning when driving normally, even on typical suburban roads.

At this price point we'd expect the ride to be more comfortable and settled. But this is unlikely to be a deal breaker for most people.

Otherwise, the Model Y drives like most electric cars with instant and quick acceleration, direct steering and it’s all done in silence which makes commuting far more pleasant than idling in the traffic with a petrol or diesel engine and a transmission constantly shifting from first to second and back.

And apart from not using petrol or diesel that's the appeal of electric cars; how easy they are to drive. 

What would make life even easier is a head-up display or driver’s instrument cluster because the current central screen set-up, which shows the speed in a fairly small size in the display's top right corner, is far from ideal.

There have been cases reported on Australian Tesla forums where displays have broken making the car illegal to operate and if this happens out of warranty the repair can be costly.

Be aware, too, that the 'Full Self-Driving' abilities of the Model Y are restricted in Australia. The law states that some autonomous tech can be used, such as adaptive cruise control with lane changing, but you must keep your hands on the wheel.  

The Model Y was given the maximum five-star ANCAP rating in 2022, scoring incredibly well for occupant protection for adults and children. The advanced tech on board includes AEB, lane keeping assistance and blind-spot warning.

Great all-round camera vision is offered by the Model Y, too, which is very much needed for rear vision given the back window's modest viewing aperture. 

For child seats there are three top tether anchor points and two ISOFIX mounts in the second row.

The Model Y doesn’t have a spare wheel, but there is a puncture repair kit.

Quick note about the lack of physical buttons. I found not having easy to access physical climate control dials distracting. Most of the car’s other functions are also housed in the media display and I feel this is a potential safety issue.

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.

When it comes to ownership the Tesla Model Y is covered by a four-year/80,000km warranty which falls short of the Hyundai Ioniq 5’s five-year, unlimited kilometre cover and Kia’s seven-year, unlimited km promise on the EV6.

As for the battery warranty, Tesla will cover it for eight years or 192,000km, which is better than Hyundai’s eight year 160,000km deal and seven years or 150,000km from Kia.

The Model Y has condition-based servicing, meaning it will tell you when it wants to go to a Tesla workshop.
