Mercedes-Benz GLA45 vs Mahindra XUV3XO

What's the difference?

A performance SUV should be an oxymoron and is no doubt a niche product. Is it a high-riding hot hatch? Or a mega-potent small SUV?

Turns out the Mercedes-AMG GLA 45 S is a bit of both and delivers the thrills of a performance car without any of the packaging or comfort-related issues.

While it is getting a little expensive at over $100,000, its blend of space and pace is hard to beat.

So, what do we make of the Mahindra XUV 3X0?

After our first taster in India, we are pleased with its presentation inside and out, packaging, quality and equipment levels.

And while driving around a brand’s own proving ground cannot give a true indication of how a vehicle performs, steers, handles, rides and stops, our initial impression is that this is an easy, confident, responsive, agile and comfortable small SUV from behind the wheel. More or less.

Of course, not knowing pricing limits a definitive verdict, but the 3XO looks promising, and we’re keen to drive it on Australian roads very soon, so watch this space.

Better still, it is obvious that Mahindra is serious about cracking Australia’s small SUV market, since the 3XO ticks so many of the essential boxes.

In the face of largely cheap yet disappointing rivals out there, that’s a very good thing.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The most obvious tell that the GLA 45 S is something a little special is the Panamericana front grille, an ode to the 1952 Mercedes 300 SL, which is found on all of the German brand's hot models.

But if that wasn’t enough to give it away, the reworked bumper with larger intakes, red-painted brake calipers, lower ride height, black exterior trim and 20-inch wheels should help.

Coming round to the rear, if the AMG and GLA 45 S badges aren’t enough to give away this car’s sporting intent, the quad-exhaust tips and diffuser are sure to give any tailgaters pause.

Our car also came with the optional 'Aerodynamics Package', which adds front fender flicks and a massive roof-mounted rear wing for an even racier look.

If you think the GLA 45 S looks a bit like a jacked up hot hatch, you aren’t far off. Overall, we reckon Mercedes has done a great job at translating the aggressiveness of its A 45 hatch to the larger, higher-riding GLA.

Without the aero package optioned, you might even call it a bit of a sleeper, and it’s certainly more subdued in styling compared to its Audi RS Q3 rival.

In fact, the GLA 45 S might be too subtle for such a hot SUV, at least for our tastes.

Whereas the A 45 S and CLA 45 S get bulky fenders and a hunkered-down, aggressive stance, the GLA 45 S could just blend into the sea of SUVs seen out on the streets, especially without the aerodynamics package added.

Your mileage will vary though, and for some, the subtler looks will be a positive.

Anyone who has sat in a recent small Mercedes should feel right at home in the GLA 45 S, and that’s because it shares much of its interior design with the A-Class, CLA and GLB.

As mentioned before, the 10.25-inch centre screen takes care of multimedia duties, but there are also clicky and tactile buttons underneath for climate controls.

Key to the interior design though is an all-digital instrument display, which is laid out on the high-definition 10.25-inch screen.

With two screens facing you, you might think it’s a bit of information overload, but you can tweak each display to show the information you want.

The digital instrumentation might not be as intuitive as Audi’s 'Virtual Cockpit', but the layout and design of the interior is easy to use and offers owners plenty of customisation to get it right.

The 3XO is not quite as new as it looks.

Although only on sale in India since last year, the newcomer is actually based on the decade-old SsangYong Tivoli, which was the first model under Mahindra’s brief ownership of the Korean brand (now under KGM control since 2023).

And, if you’ve visited India lately, you might have seen a substantially modified Mahindra version of the Tivoli, badged XUV300 and sold for five years there from 2019, and the actual basis for the 3XO.

Now, Mahindra says that the latter is around 80 per cent new, with fresh sheetmetal clothing the bones of its predecessor(s). And they’re quite contemporary threads, with crisp surfacing, striking LED lighting, clean grille finishes and a pert rear-end design.

Subaru would be proud of the squared-off wheel arches, lofty 201mm ground clearance and sub-four-metre length, while the latter helps keep the small SUV inside an Indian tax bracket. Fun fact: that’s why the old Ford EcoSport, also from Chennai, needed its spare wheel mounted on the tailgate.

The 3XO's length/width/height/wheelbase of 3990mm/1821mm/1647mm/2600mm respectively, puts the 3XO on the stubbier side of the crossover brigade. Yet with more clearances than almost all alternatives. This is crying out for a rugged 4x4 ‘Outback’ treatment.

Overall, then, the smallest of Mahindras is an effectively chunky update, with a height and stance to handle the rough and tumble of urban driving.

The new-generation GLA 45 S has grown in all dimensions compared with its predecessor, making it much roomier and more practical than before.

For reference, it measures 4438mm long, 1849mm wide, 1581mm tall and features a 2729mm wheelbase, but still sports a roomy cabin for four adults, especially in the front seats.

Storage options include decent door pockets that will accommodate large bottles, a deep centre storage bin, smartphone cradle that doubles as a wireless charger, and two cupholders.

Being a small SUV, the rear seats also afford plenty of room for occupants, with more than enough space for head, shoulders and legs – even with the front seat adjusted to my 183 cm (6'0") frame.

There are decent door pockets, air vents, and USB-C ports that should keep passengers happy on long trips, but the GLA 45 S doesn’t have a fold-down armrest or cupholders for the rear seats.

The boot, however, is where the GLA 45 S really starts to make a case for itself compared to the A 45 S.

The boot boasts 435 litres of volume, and can expand to a massive 1430L with the rear seats folded – making it about 15 per cent bigger than the A 45 S – while the higher load height should make loading and unloading groceries a bit easier. 

A downside of the GLA’s tech-focused interior, though, is that all the USB ports are now USB Type-C, meaning you’ll likely have to carry around an adapter to use your old cables.

Mercedes is generous enough to include one with the car, but given most device chargers are still USB Type-A, it is something to be aware of. 

Mahindra reckons that even though the 3XO is only four metres long, it's got the space and the practicality of some 4.7m SUVs.

Which sounds dubious, but first impressions inside reveal ample room for legs, shoulders and heads, even in the sunroof-specced AX7L. Sat high, vision is impressive too, aided by an excellent driving position on nicely-shaped seats, deep glass areas and handy 360-degree camera views.

Based on the old dashboard architecture but with a completely redesigned central touchscreen and electronic instrumentation pod (and both measuring in at 10.2 inches), the effect is modern enough, with a very welcome avoidance of screen-based buttons for actual switches that are incredibly easy to navigate.

In fact, the sheer user-friendliness of the 3XO’s interior is commendable, from the world’s deepest glovebox and chilled centre bin (in the AX7L only) to the various USB ports, cupholders and storage options. The climate control effectiveness is a given if any Indian vehicle is to succeed. And the material fit and finish seemed fine. About the only dislike is the lack of steering-wheel reach adjustment, betraying the Mahindra’s real age.

Moving to the row behind, there’s sufficient space for a pair of 180cm adults, on comfy cushions. Again, vision, storage and all amenities rate highly, with face-level vents especially appreciated at this price point. The 3XO is pitched as a sensible family-car proposition in India so the back-seat area is crucial.

Behind that is the boot, which is fairly large as well, aided by a low floor and a large hatch aperture, while a space-saver spare lurks underneath, so no stupid tyre-repair kit for this sensible small SUV.

There’s also a lot of room under the bonnet…

At the time of publishing, XUV 3XO (here-on in referred to as 3XO) pricing hadn’t been confirmed. But, we’re instructed that the entry-level AX5L will start from “about $25,000”, placing it right among the sharks.

But Mahindra is out for blood, so keyless entry/start, synthetic leather trim, a 10.2-inch touchscreen and 10.2-inch driver display, wireless Apple CarPlay/Android Auto, a surround-view camera, dual-zone climate control, electric folding mirrors, roof rails and 16-inch alloys – with a spare – are included.

From “well under $30K”, the AX7L ushers in 17-sized rims, a panoramic sunroof, Harman-Kardon audio, a chilled glovebox, fog lights, front parking sensors and a shockingly powerful (pun intended) 65W USB-C port to (more than) make up for a missing wireless charger pad.

Lined up against its Chinese and South Korean rivals, the 3XO’s specification is largely on the money. Largely.

However, no DAB+ digital radio is an oversight, and although the Mahindra includes must-have advanced driver-assist safety systems (ADAS) like autonomous emergency braking (AEB) and lane-support tech, it misses out on some secondary nice-to-have alerts optionally available on some rivals – more on them in the safety section later on.

Now, if you’re thinking that the 3XO might look a bit familiar, your eyes aren’t deceiving you. And there’s a very solid reason for that.

Powering the Mercedes-AMG GLA 45 S is a 2.0-litre turbocharged petrol engine, outputting a staggering 310kW/500Nm.

This means the new car jumps up 30kW/25Nm compared to its predecessor, explaining (at least in part) the price jump.

The GLA 45 S is also the top-spec version globally. The 285kW/480Nm GLA 45 which is available overseas would be more directly comparable to the old car.

The engine is also the most potent production 2.0-litre on earth, and is shared with the A 45 S and CLA 45 S.

Paired to the engine is an eight-speed automatic transmission, which sends drive to all four wheels via Mercedes’ '4Matic' system.

As a result, the GLA 45 S will accelerate from 0-100km/h in a frighteningly quick 4.3 seconds, and carry on to an electronically limited top speed of 265km/h.

This is 0.4s slower than its A 45 S sibling, in part due to its heftier 1807kg weight.

It might be tiny and a cylinder down compared to almost all of its Asian rivals, but Mahindra’s in-house 1.2-litre three-cylinder turbo-petrol engine follows European downsizing convention.

This means it relies on advanced technologies to produce comparatively healthy power and torque outputs, being 82kW at 5000rpm and 200Nm between 1500rpm and 3500rpm respectively.

Coming in at around 1400kg, the result is a power-to-weight ratio of about 59kW per tonne, which is modest against the slightly heavier Tiggo 4’s 76kW/tonne, for instance.

Driving the front wheels is a Toyota-made six-speed torque-converter automatic, so no droney CVTs or laggy dual-clutch transmissions here. But we’re disappointed the six-speed manual gearbox offered elsewhere isn’t even an option in Australia, especially after driving the Mahindra.

Official fuel consumption figures for the GLA 45 S are pegged at 9.6 litres per 100km thanks in part to an engine start/stop system.

We managed 11.2L/100km after a few days of testing around Melbourne’s inner city and winding country back roads, but those with lighter feet will no doubt come closer to the official figures.

A performance SUV that can ferry kids and groceries, out accelerate  nearly everything else on the road, and sip around 10L/100km? That’s a win in our book.

The official Australian combined fuel consumption average is 6.5 litres per 100km, which translates to 137g/km of carbon dioxide emissions. With a 42L tank, should equate to about 640km per refill.

Urban and Extra Urban numbers are 7.6L/100km and 5.9L/100km respectively.  

Just keep in mind that the 3XO is recommended to drink from the 95 RON premium unleaded petrol bowser.

If the bespoke styling wasn’t enough of a giveaway, all it takes to realise you are behind the wheel of something special is to turn on the GLA 45 S.

The prodigious engine is fantastic in the A 45 S and CLA 45 S and is no different here.

With peak power coming in at a heady 6750rpm and maximum torque available from 5000-5250rpm, the GLA 45 S likes to rev and makes it feel a little like a naturally aspirated engine in character.

Don’t get us wrong, once the boost becomes available, you will feel that shove into the back, but it’s great that Mercedes has made the engine perform a little more predictably.

Paired to the engine is a smooth shifting eight-speed dual-clutch automatic transmission, which is one of the better versions I've experienced.

Many DCT bugbears, such as jerkiness at low speeds and clunkiness when putting into reverse, aren’t apparent here, and the transmission is up to the task when puttering around town or when driving spiritedly.

Speaking of which, the GLA 45 S’ different drive modes will easily change its character from tame to wild, with available options including ‘Comfort’, ‘Sport’, ‘Sport+’, ‘Individual’ and ‘Slippery.’

Each mode will tweak the engine response, transmission speed, suspension setting, traction control and exhaust, while each can also be mixed and matched in the ‘Individual’ drive mode.

However, a missing feature for the GLA 45 S that is found in its A 45 S and CLA 45 S siblings is a drift mode.

Sure, how many small SUV owners are going to take their car to a track to make use of it, but it still would have been nice to have the option.

With three levels of suspension setting, though, the GLA 45 S offers enough variability to be comfortable around town and soak up the bumps thanks to its long suspension travel, while also switchable for a more involved, driver-focused feel.

The GLA 45 S might never corner as hard or fast as its A45 S sibling, but being an SUV brings its own unique set of plus points.

There’s much made about how strong and rigid the 3XO’s platform is, and it’s not just for better crash protection.

Aided by a typical MacPherson-style strut front and twist-beam rear suspension set-up, Mahindra reckons it has dialled in just the right amount of dynamic finesse to make this small SUV the keen driver’s choice.

To find out if that’s the case, we spent a couple of hours behind the wheel of one at Mahindra’s vast proving ground near Chennai. A 180km/h high-speed loop. A set of chicanes. And a few rough surfaces where we could find them. Just a taster, really.

The overall impression is that nothing betrays the 3XO’s ageing platform from behind the wheel.

Torquey and smooth, the 1.2-litre three-cylinder turbo petrol engine is punchy off the line, possessing a sporty, peppy nature as well as an endearing willingness. Adding to this is the six-speed auto, as it’s also pleasingly responsive, with no lag or jolts. This is how small turbos should behave.

We managed to max it out at almost 170km/h (indicated) on the speed bowl, where it felt dead-set stable and secure. Impressive, given the 3XO’s height and ground clearance.

But the steering seems too light and a little disconnected during low-speed manoeuvres, at least for keener drivers, but once velocities climb, it seems to weigh up with sufficient heft. This is reminiscent of the way that Volkswagens used to tune its steering some 25 years ago. Maybe that’s the biggest sign of the Tivoli’s bones lurking underneath.

What this means is that the Mahindra is not the sort of SUV you buy if you absolutely relish driving, in the way the Mazda CX-3 or the very sadly-missed Ford Puma are. Hopefully, we’ll be pleasantly surprised on Australian roads.

We never got a chance to test the suspension’s ride quality, but over the couple of bumps that we did traverse, it seemed to soak them up well enough. And even though our test 3XO lacked the (optional) rear parcel shelf, road and tyre noise seemed sufficiently contained. Again, Australian roads will reveal all.

What we can say with some confidence is that the little Mahindra is a lively, user-friendly, comfort-biased and civilised small SUV. No glaring faults or anomalies appeared, just a cheerful, charming character.

For what it represents, the 3XO seems properly engineered and tuned.

Perhaps all those years ironing out the bugs in the preceding XUV300 and Tivoli are paying dividends for today’s buyers.

We weren’t expecting that.

No Australian or European NCAP crash-test rating exists for the 3XO.

But it does include AEB with cyclist/pedestrian detection, forward collision warning, lane keep assist, traffic sign recognition, lane departure warning, high beam assist and adaptive cruise control with Smart Pilot Assist, as well as six airbags.

Plus, ISOFIX fixings are fitted to the rear seats, along with a trio of child-seat anchorage points.

However, neither grade offers rear cross-traffic alert and a blind-spot monitor, meaning the XUV 3XO may struggle to achieve a five-star ANCAP crash-test rating at this time.

That said, it recently scored five stars in India’s new (but less-stringent) Bharat NCAP test, aided by extensive body strengthening and crash-force mitigation engineering development at Mahindra’s world-class research and development centres in India.

And there’s still more safety development underway, ahead of next year’s planned ANCAP test.

Like all new Mercedes-Benz models, the GLA 45 S comes with a five-year/unlimited kilometre warranty with five years of roadside assist – the benchmark in the premium car space.

Service intervals are every 12 months or 20,000km, whichever occurs first, and the first five services are available to purchase for $4300.

This actually makes the new GLA 45 S cheaper to maintain over its first five years than the outgoing car, which costs $4950 over the same time period.

Mahindra offers a seven-year warranty with roadside assistance, and that is excellent news for most buyers. But the 150,000km cap when most other brands have unlimited mileage might fall a bit short for some prospective buyers’ requirements.

At the time of publishing, no service scheduling and capped-price servicing pricing information was available, but expect these to be announced after early July 2025.
