Mercedes-Benz GLA-Class vs Land Rover Discovery Sport

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 Land Rover Discovery Sport P300e has a beautiful and practical cabin space. The powertrain didn't always convince me on the road but it does offer decent economy, if you charge it often.

The media system left a lot to be desired and having to pay around $15K extra for all of the customisations means it's not as affordable as what it initially seems. Still, if you’re looking for a plug-in hybrid with a great cabin and on-road looks, this is a good option.

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 updated Disco Sport gets new underpinnings which are shared with the Range Rover Evoque.

The body has seen a minor facelift but honestly, it’s so slight only die-hard fans will notice anything different. Overall, it still has the styling that people know and love.

It’s once you head inside that the facelift becomes far more apparent. Gone is the more traditional looking e-shifter and in its place is a rather nubby-looking one.

The dashboard looks more streamlined and features wider padded accents and in our test model, we have the Oyster and Black upholstery which does make it look quite luxurious. There are a few too many blank spaces for me personally but it looks slick.

Accentuating the dashboard is a floating-effect multimedia system and a large digital instrument cluster – both of which look great but there are no other control buttons or dials. I’m not a fan of the fact that you’re 100 per cent reliant on the tech screens and I'll explain why in the Practicality section.

The optioned panoramic roof makes the cabin feel airy and it's cool that it has a memory function – it will close when you turn off the car but reopen upon starting again.

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.

With it's 4597mm length, 2173mm width and 1727mm height, the Discovery Sport is technically classed as a medium SUV but the cabin space is much larger than it has any right to be.

Both rows have ample head- and legroom for both my 168cm (5ft6') height and those much taller. When you have a co-pilot, you’re also not jostling for elbow room and it’s easy to slide in and out of because of the 212mm ground clearance.

The amenities up front are good with the update seeing more decent sized individual storage options.

There are two cubbies in the centre console as well as two cupholders and a medium-sized middle console. The glove box can hold more than a manual and the storage bins with their single drink bottle holders are also larger than before.

The powered front seats are comfortable and the optioned heat functions are most welcome on the cooler days we've been having lately.

The back seats also have superior padding comfort but you sit on top of, rather than in, them which is typical of an SUV.

The amenities and storage are what you would expect for the grade level with a fold-down armrest with two cup holders and small storage cubby, directional air vents, reading lights, map pockets and small storage bin in each door.

There is also an accessory hole to attach device holders on the backs of the front seats - perfect for hooking up a screen for little ones on a long journey.

The P300e loses points on its practicality with the multimedia system. You eventually get used to using it while on the go, even though the lack of buttons/dials means more time is spent with your eyes on the screen.

That's when the screen turns on. The display has cut out a few times this week and the wireless connectivity for Bluetooth and the connection for Apple CarPlay (wireless or wired) drops out a lot.

The P300e I'm driving is brand-spanking-new, so it may just be a case of something that needs calibrating but for a lot of the Land Rovers I've sampled in the past, the media system seems to be the area with the biggest teething issues.

That being said, the built-in satellite navigation is top-notch and easy to use. The directions also get displayed on the instrument cluster and optioned HUD.

The charging options are excellent with the front row getting three USB-C ports and a large wireless charging pad. The rear gets two USB-A ports and two USB-C ports plus a 12-volt socket and the boot also has a 12-volt socket. Totally spoiled for choice.

The boot is a great size at 897L with all seats in use and that jumps up to 1749L when the rear seats are folded flat. The rear row also has a 40/20/40 split, which opens up storage opens.

There is a temporary spare tyre housed underneath the flat floor and a powered tailgate comes standard in this model, which I always like.

The Discovery Sport is offered in four grades and the model on test in this review is the plug-in hybrid mid-level P300e.

The P300e is priced from $102,125 before on road costs but the addition of the plug-in hybrid powertrain means that it is actually $8855 more expensive than the flagship HSE.

In terms of its rivals, the P300e sits towards the middle of the line-up with the Volvo XC60 Recharge Plus PHEV coming in as the most affordable at $92,990 before on-road costs, then the Lexus NX450+ PHEV at $93,498. Sitting at the more expensive is the Audi Q5 55 TFSIe at $106,600 and then the BMW X3 xDrive30e M Sport PHEV at $111,800.

However, our test model does have a few optioned extras which ups the price tag and its position in the pack.

Those options include:

- A Technology Pack for $4700 which adds a digital rearview mirror, head-up display, and a 360-degree camera system with wade sensors.

- A fixed panoramic roof for $3040.

- Upgraded Meridian Surround Sound System for $2220.

- Upgraded 20-inch alloy wheels for $2080.

- Heated front seats for $860.

- Home charging cable for $520.

- Titanium mesh trim for $420.

All of that brings the grand total to $117,290, before on roads. Which is no small lump of change for what is essentially just a baby Land Rover.

Standard luxury and practical features include powered front seats with a three-position memory function for the driver, synthetic leather upholstery, keyless entry, push-button start, powered tailgate, temporary spare-tyre, and dual-zone climate control.

Technology includes an 11.4-inch touchscreen multimedia system, 12.3-inch digital instrument cluster, Android Auto, wireless charging pad, Bluetooth connectivity, and DAB+ Digital Radio.

The update also sees wireless connectivity for Apple CarPlay, an Amazon Alexa app, as well as new USB-C ports, as opposed to USB-A ports from the previous model.

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 Discovery Sport P300e has a 1.5-litre, three-cylinder plug-in hybrid turbo-petrol engine with an eight-speed auto transmission and is an all-wheel drive.

The engine produces a combined power output of 227kW and 540Nm of torque. On paper, it’s punchy and can do a 0-100km/h sprint in 6.6 seconds but in practice, it’s not always great at using that power.

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 official combined fuel cycle consumption figure is 2.1L/100km and my real-world usage sits a 4.8L/100km after doing some open-roading and lots of urban trips this week. For an SUV of this size and with it's power, that's pretty darn good.

The trick is to regularly charge it for maximum fuel economy gains and that's not always practical.

Officially, you get up to 66km of pure electric range in this but expect closer to 47km in the real world. 

The P300e has a Type 2 CCS charging port which means you can hook this up to a fast charger. On a 50kW system, you can go from 0-80 per cent in as little as 30 minutes but on a 7kW system, going from 0-100 per cent jumps up to to two hours and 12 minutes.

Expect to leave it on charge overnight on a standard domestic socket.

The driving range based on the official combined fuel cycle is obscene, and I can't see it happening in real life - so, based on my fuel economy figure and the 58L fuel tank, expect a theoretical driving range of up to 1208km.

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 Discovery Sport P300e has the goods on paper when it comes to power and it does... once you're up to speed. That's when you can punch it and feel confident at overtaking or keeping your speed consistent on hills.

It's when you're accelerating from a full-stop that it becomes a bit lacklustre as there's serious lag between accelerating and actually moving forward. Accept that you will have to accommodate for this inaction whenever you are joining or crossing traffic from a standstill.

Besides this little hiccup in the power delivery, handling on the whole is good.

The Disco Sport is easy to manoeuvre and you don’t feel like you’re driving something big, despite the ample cabin space. It also handles itself well in corners without too much roll.

The switch between the electric and petrol components isn’t always the smoothest but when it’s in its electric mode it’s blissfully quiet. The cabin feels refined too because you don’t get a lot of external noise in the cabin at all.

The wide windows and higher ride means visibility is great and the optioned digital rearview mirror adds another viewpoint if the back window isn’t clear.

The Disco Sport proves to be nimble and easy to park with the optioned and clear 360-degree camera system, and the sensors at the front and rear are sensitive.

The Discovery Sport plug-in hybrid variant is not covered by its siblings' five-star ANCAP safety rating from 2022, so the P300e is unrated but features some good safety gear.

Standard items include AEB, blind spot monitoring, driver attention alert, tyre pressure monitoring, rear collision warning, forward collision warning, rear cross-traffic alert, lane keeping aid, traffic sign recognition, intelligent seatbelt warning, and adaptive cruise control.

The traffic sign recognition tech is dreadfully intrusive, which impacts the driving enjoyment. I turn the warning sound alerts off each time I hop in as it's like a small child is hitting the same piano key over and over again - just to give you a sense of the sound itself and resulting annoyance.

It has seven airbags but interestingly, and unusually, the seventh one is a pedestrian airbag.

This model misses out on lane departure warning but for any families, there are ISOFIX mounts on the rear outboard seats plus three top tethers and you should be able to get three seats back if they’re not too big.

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 Discovery Sport comes with a five-year/unlimited km warranty and the battery is covered by an eight-year/ 160,000km warranty which is a usual term to see for this class now.

There is a five-year capped-price servicing program which costs a flat $2100, or $420 which is both reasonable for the class and is more affordable than a pay-as-you-go option. There is also a five-year roadside assistance program as a part of your servicing plan through Assist Australia.

Servicing intervals are great at every 12 months or 20,400km, whichever occurs first.
