Mercedes-Benz Gls450 vs Zeekr X

What's the difference?

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

It's a good thing in a small package, this Zeekr X, and there are a lot of things I like about it. In fact, the only sticking point for me is the price. But that's all about perspective. If you see this as a newcomer Chinese brand, then yes, there are a lot of more affordable options out there. But if you see it as a premium player, it's really a more affordable version of a Volvo.

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

The visual changes aren’t massive. This AWD version welcomes a couple of new exterior colours, including the 'Matt Khaki Green' of our test car. It also gets the two-tone black roof and there are new 20-inch alloy designs.

Elsewhere, it's the futuristic-style of design we’re used to which differentiates the X from its Volvo EX30 twin under the skin.

Inside, this is a seriously well-equipped and polished-feeling small SUV, and — unlike some of the newcomer brands to Australia — it all feels very high quality and well put together. And that includes the material choices.

I don’t even hate the fact that most of the functions are controlled via this screen, thanks to the little shortcuts glued to the home screen. I do, however, hate the fact that there’s no easy way to change the wing mirrors or shortcuts for toning down some of the safety stuff.

That aside, though, it’s a nice and high-quality feeling space.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

You know you're in a small vehicle when you can't fit two large (not those crazy American-style jumbo cups, just normal coffee-shop takeaway) coffees in the cupholders, but so it is with the Zeekr X.

The small SUV's 4432mm length, 1836mm in width and 1566mm height doesn't leave much room to spread out up front. There's ample room for driver and passenger, of course, but we are talking about a small vehicle here.

Clever storage helps to mitigate that, though, especially the super-deep storage space in the centre console and the very clever fridge that separates the driver and passenger seats.

Weirdly, though, the space doesn’t feel overly tight in the back seat. We had a massive baby seat in there, and that fit without issue. And full size humans can genuinely get pretty comfortable. I'm 175cm, and I had enough knee and headroom.

In the boot, there’s 404 litres of volume with the rear seats upright and 1247 litres with them folded flat. And it’s worth pointing out this isn’t intended to be a family car, but there’s certainly enough space for the shopping... and a pram.

This is a small SUV with a LOT of stuff. There are two trims in the Zeekr X range – the entry-level rear-drive model is $48,900, drive-away, while the all-wheel drive version we've tested is $57,900 on the road.

The obvious comparison is to the Volvo EX30, which shares its platform with the Zeekr X through both brands' Chinese parent company Geely.

As of right now, the cheapest single-motor Volvo is $56,051, drive-away in NSW, or $49,990 plus on-roads, making the Zeekr version much, much cheaper.

Anyway, outside there are 19- or 20-inch alloys, though our test car is fitted with the optional 20-inch black alloys, paired with a black-with-red-highlights interior treatment, which adds $2000 to the price.

Ours is also fitted with the electric front doors which open or close at the push of a button, and back doors that unlatch, but don’t fully open, the same way, which adds another $2000.

Both trims also get heated and cooled front seats, and heating in the rear window seats, but this AWD version also adds a massage function for front seat riders. 

There’s also wireless charging, a 13-speaker Yamaha sound system and — very cool, literally — is the little drinks fridge between the front seats in the AWD variant.

Tech is handled by a 14.6-inch touchscreen with Apple CarPlay and Android Auto and there’s a head-up display for the driver.

The GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

The big news here is a more powerful rear motor – meaning you get more grunt whether you opt for the rear-wheel drive or this all-wheel drive.

In rear-drive form, that boosts your outputs from 200kW to 250kW, dropping the sprint to 100km/h to 5.6 seconds. In AWD guise, your new outputs are 365kW (up from 315kW) and 573Nm, and your sprint to 100km/h falls to 3.7 seconds.

Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

This is where it starts to get weird. The rear-drive Zeekr X is fitted with a 61kWh LFP battery, which can accept up to 230kW DC fast charging, taking you from 10 to 80 per cent charged in just 18 minutes. Total claimed range is 405km.

The flagship AWD, though, charges at a slower rate. It gets a 66kWh NMN battery and can only be charged at 150kW, meaning the same charge takes 30 minutes. Zeekr is promising a 415km driving range between charges.

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

Short answer? Pretty good, with some caveats.

I'm partial to a firmer ride. I find some Chinese car companies can feel like they get their suspension bits from Captain Snooze, such is the soft, pillowy ride served up. And to be honest, it makes me a little seasick at times.

The Zeekr is not like that. It has firmness dialled into the ride equation and can feel harsh at times, but also improves the drive experience, delivering connection and engagement at the cost of some sharpness on the wrong road. 

It's also faster than the model it replaces, but it's also one of those cars in which the real-life feeling doesn't quite match the on-paper promise.

This thing serves up supercar speed, but it doesn't feel like it from behind the wheel. Instead, the acceleration - especially from a rolling start - feels potent, but not biblical.

From a standing start it pauses for a moment, almost like an internal-combustion vehicle might, before delivering a quick (but not stratospheric) flow of power. None of that is a bad thing, by the way. Who wants their small SUV to accelerate like a supercar?

It's otherwise an entirely pleasant drive. The cabin is serene and quiet and it's a small car that doesn't feel like one. There's nothing light or tinny about the drive experience, instead there's a heft and quality.

The Zeekr X wears a maximum five-star ANCAP safety rating, earned in 2024, which means the long list of required active safety stuff is present and accounted for, all wrapped up in what Zeekr calls its 'Intelligent Driving Assist System'.

There are five cameras, five radars and 12 sensors, which is a crazy number for a car this small.

And this is also not a car in which I was desperately trying to figure out how to deactivate any of the active safety systems – save the overzealous over-speed warning – which is a win these days, too. 

There are also seven airbags, including a centre front airbag.

The Zeekr X is fitted with ISOFIX anchors on the rear outboard seats and top tether anchorages for all rear seating positions.

The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.

Zeekr's coverage is an underwhelming five-year, unlimited-kilometres, while the drive battery is covered for eight-years or 160,000km. There’s five years' of roadside assistance thrown in, too.

Service intervals are 20,000km or 12 months, with five years' of ownership setting you back a hefty $3072; an average of $614 per workshop visit.

There are currently 16 Zeekr dealers in Australia - two of which are 'pop-up' sites rather than full retail centres.

Multiple locations in Melbourne, Sydney and Brisbane with the ACT, Adelaide and Perth also covered. Others include Geelong and the Sunshine Coast but so far you're out of luck in Tassie or the NT.
