Mercedes-Benz G63 vs Kgm Actyon

What's the difference?

The Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

Is all of the above enough to spur you into Actyon? It should be, or at least make your medium-SUV shortlist.

Bold styling, keen pricing, an inviting cabin, loads of space and an involving driving experience make the new KGM everything we wanted from but never really got from the old SsangYong.

A bit more torque, a little less thirst and a softer ride would make a surprisingly good family-friendly medium SUV a real crowd pleaser.

We’re looking forward to what else KGM has coming in the future.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

KGM currently sells no fewer than three medium-sized SUVs of roughly similar dimensions.

There’s the more-compact Korando (which arrived in 2020), the bigger and boxier Torres (released in 2024) and, of course, the new Actyon. While all sit on variations of the same monocoque-bodied platform, the newcomer benefits from additional development (and funds) under KGM ownership.

Not obvious unless viewed together, the Actyon is designed to be a sportier and more coupe-like take on the Torres, and is slightly lower at 1680mm as a result. But it’s also a bit longer at 4740mm and wider at 1920mm wide. Both share the same 2680mm wheelbase.

This may seem an extravagant niche for KGM to pursue, but it claims the original SsangYong Actyon (unveiled in 2005) beat the admittedly far-more influential BMW X6 by about three years, to become the world’s first productionised coupe-style SUV.

Whatever, today’s Actyon is a sleeker and perhaps prettier design than the Torres, with obvious Range Rover (Evoque, Velar) homages throughout, particularly when it comes to the lighting elements.

According to KGM, the grille’s lighting design is inspired by the four symbols found on the South Korean flag, representing heaven, earth, water and fire.

A nod to SsangYong’s reputation for tough, rugged vehicles are the controversial bonnet-mounted ‘handles’, a decent ground clearance rating of 206mm, squared-off wheel arches, unusually-wide C-pillars and clear Jeep Grand Cherokee overtones in the tail-light and other rear-end treatments.

What should be a visual mess seems to meld together cohesively regardless of influence, making the Actyon a distinctive, handsomely-offbeat design.

The G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

Inside is where the Actyon really gets into its groove, as an impressive, thoughtfully engineered family-sized SUV.

Big doors open up nice and wide, revealing a welcoming interior, with a sense of space and airiness, aided by deep windows, large mirrors, a lofty driving position and – in our top-spec K60 test vehicle – the vast glassy sunroof above.

The sporty front seats look and feel fab, fit like a glove and offer plenty of adjustability for a broad range of backs and bottoms alike.

A chunky square-ish steering wheel is good to grip, and, along with the instrumentation’s distinctively angular graphics, gives off lots of BMW vibes.

In fact, it is clear that KGM has been inspired by its latest round of up-spec Kia, Hyundai and even Genesis compatriots when it comes to the Actyon’s fit, finish and presentation. There seems to be no concessions of quality or ambience in order to maintain the Actyon’s keen pricing, and that’s remarkable.

Especially as most things work so well.

Let’s take the 12.3-inch central display. No physical buttons are present, unfortunately, and that’s probably partly due to the modern, clean, horizontal look that today’s designs seem to adopt wholesale.

However, the difference here is that it does not quite suffer the same pitfalls as normal software-based, electronics-heavy set-ups.

Along the left side of the main screen border is a row of permanent fast keys for home, media and climate. Up the top of it is a tab for a temporary menu for fast access to driving modes, stop/start on/off, traction control, camera views, vehicle settings and general settings. While down the right-hand side of the screen border and close to the driver for easy access is a swipe-left tab for a detailed computerised climate-control display. This takes up one-third of screen real estate.

Sounds complicated but it is actually disarmingly intuitive. You're still prodding and swiping screens, and that’s always a potentially-dangerous distraction. But at least nothing is more than a double action away. And almost all functions are also accessible in a dedicated widget home screen. Handy.

Helpfully, KGM also provides a big, physical button on the steering wheel as a ‘favourites’ fast-key to whatever you use most. We set ours for direct drive mode access.

Meanwhile, all of the Actyon’s other main cabin functions, including the climate control, endless storage, twin USB-C ports, varying interior lighting and audio sound of adequate quality, operate without complaint.

Now, while the upper-level materials seem premium, cold and hard lower plastics beg to differ, yet they neither look nor smell cheap, so that’s a win.

But all these favourable first impressions don’t mean there isn’t any room for fixes in this South Korean family truckster.

At the very top of that list should be turfing out the very, very fiddly drive selector. Imitating Volvo’s infinitely more-effective toggle functionality, it needs two, three and even four stabs at selecting Drive or Reverse before engaging. This is a form of torture.

Running close behind is a multimedia system that needs at least 20 seconds to boot up on initial start-up. Not every time, just after a period of inactivity. Painfully slow, it’s also a hazard as the reversing camera won’t operate during this time! Fail.

Other annoyances include the lack of digital radio and wireless Apple CarPlay/Android Auto, meaning you’ll need a cord to access both via your smartphone. And finally, that C-pillar is a massive blind spot.

Meanwhile, out back, all the expected (but not always available in others) amenities are present, like air vents, twin USB-C ports, overhead grab handles, reading lights, coat hooks, a folding armrest with cupholders and an abundance of storage.

But there is also a shocking number of surprise and delight features, including electric front passenger seat adjustment – for slide and recline, adjustable backrest angles, outboard seat heaters, side window blinds, tablet holders incorporated into the back of the front headrests, shallow pockets for smartphone storage set within the larger map pockets, huge door pockets that can hold a 1.5-litre bottle and a back-row speaker-mute function for weary rear-seat travellers needing peace.

When parked, there’s enough space with the backrests dropped for a 180cm person to sleep flat on their back, highlighting the 1440 litres of cargo capacity, or an impressive 668L with all five seats up.

The only note here is that there is no luggage cover to hide valuables (or snooze underneath). Lucky the glass is all heavily tinted. Beneath the floor is a space-saver spare wheel, thankfully.

Overall, then, the Actyon’s cabin is a cavernous, classy and well-equipped affair.

If you love an underdog, you’ve come to the right place, because the Actyon – a portmanteau of action and young – is a minor player in a major league.

Medium-sized SUVs represent Australia’s largest automotive segment. So, to help get the ball rolling, even the ‘base’ K50 grade borders on bountiful.

Kicking off from $47,000, drive-away, you’ll find unexpected little luxuries like quilted leather and heated outboard seating front and back, powered and ventilated front seats, rear privacy glass, a heated steering wheel, multi-coloured ambient lighting, automatic walk-away locking, a powered tailgate (with motion sensors) and 20-inch alloys. Entry level, remember.

Plus, a space-saver spare wheel is fitted. Rural drivers thank you, KGM!

These come on top of most of the expected modern amenities, including climate control, embedded satellite navigation, a 12.3-inch touchscreen (alongside a same-sized electronic instrument display), wired Apple CarPlay/Android Auto, heated/powered folding mirrors, a reverse camera and parking sensors all around.

Thankfully, there’s also a decent wedge of advanced driver-assist safety, like autonomous emergency braking (AEB), lane-support systems and adaptive cruise control. More on those in the Safety section later on.

For an extra $3K, the K60, from $50,000, driveaway, adds a 360-degree-view camera, a panoramic sunroof with a solid shade (again, something Australians want), rear door blinds and a wireless phone charger.

But there are a few conspicuous omissions. No Actyon offers head-up instrumentation, digital radio, wireless CarPlay/Android Auto or the option of either a hybrid powertrain and/or all-wheel drive (AWD).

Still, from a value perspective, that’s a lot of kit for the cash. K60 money can’t buy you more than a basic RAV4 GX (albeit a hybrid), while you’re only at mid-grade Outlander LS, Sportage SX, Tucson Elite and X-Trail ST-L 2WD petrol.

And that’s not even taking in the Actyon’s extra length and girth that make this five-seater seem like it should offer a third row, or the very striking styling.

So far, so good.

The G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

A familiar unit if you’re an existing Korando or Torres driver, the Actyon uses a 1.5-litre, four-cylinder, direct-injection, turbo-petrol engine.

Delivering 120kW of power at 5400rpm and 280Nm of torque between 1500-4000rpm, it drives the front wheels only at this stage via a six-speed torque-converter auto supplied by Toyota-owned Aisin.

With a power-to-weight ratio of nearly 73kW per tonne, it falls behind the larger-capacity 2.5-litre non-turbo alternatives as found in the Mazda CX-5, but matches rival 2.0-litre non-turbo units as used in the Sportage and Tucson.

A trio of driving modes are offered – 'Normal', 'Sport' and 'Winter' (to control traction in slippery conditions) – while a handy pair of paddle shifters allow for some manual-ratio manipulation, though it will still change up automatically rather than bounce on the rev-limiter.

The KGM also follows class convention in its double wishbone front and multi-link independent rear-suspension set-up, though it boasts higher-than-usual ground clearances for a front-drive medium-SUV that’s resolutely not an off-roader.

Towing capacity is rated at 1500kg with a braked trailer and 750kg unbraked.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the tank.

Without even mild-hybrid-style electrification to help improve efficiency, how does the Actyon perform when it comes to fuel economy?

The official combined cycle (urban/extra-urban) average consumption figure is 7.6L/100km with a CO2 emissions rating of 174g/km.

Which might not seem too bad, but remember this one likes to sip from the 95 RON premium petrol bowser. Filling the 50-litre tank should result in about 655km of range, on average.

So much for the theory. During our time with the Actyon, we recorded a disappointing 10.3L/100km – though it’s worth keeping in mind this included performance testing which tends to drain the tank a bit harder.

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

Okay, this the best-driving KGM ever. No shocks there, as this is the first model under the company’s new stewardship.

But it’s also the best SsangYong ever. Faint praise maybe, considering how off-road-biased and workhorse-like so many models were/still are, yet the Actyon can hold its head up high in more-sophisticated circles.

Not that pressing the starter button reveals that straight away.

With a dinky capacity and hefty, circa-1650kg mass to overcome, the 120kW/280Nm 1.5-litre turbo four needs plenty of revs to get going, meaning there’s a moment of initial lag before the speed starts piling on. Not great if you’re in a hurry. And it's pretty vocal to boot.

Essentially, the Actyon regularly has to work harder than larger-engined alternatives to achieve the same result. A quick power-to-weight calculation tells the story: 72.8kW/tonne versus 85.6kW/tonne for the 1578kg, 135kW/245Nm 2.5-litre Nissan X-Trail.

But, once on the move, there is a decent wad of torque for spirited acceleration as well as smooth throttle responses, and enough in reserve for sufficiently quick highway overtaking. We clocked 9.7 seconds for the 0-100km/h sprint.

Three driving modes are offered – Normal, Sport and Winter. Sport holds on to the ratios for a big longer, and is best suited for open-road driving.

More torque wouldn’t go astray, though, especially when the car is fully laden.

And the six-speed auto transmission, whilst smooth, can also be slow to react to downshift requests. The abrupt and clumsy stop/start system doesn’t help when moving off the line again, either.

Things improve when on the move, aided by a handy set of paddle-shifters when you’re in the mood for some manual-mode ratio manipulation, though the software does upshift if you forget.

In the wet the KGM also feels planted. And though it does not take a lot to spin the sticky Michelin-shod front wheels, it remains composed. An AWD option would probably be a welcome addition to the range. 

You’d never call the Actyon a sports SUV, but there is a keenness to the chassis tune, reflected in the strong braking and positive steering – the latter being an absolute first for a SsangYong product.

Light enough around town to be easily manoeuvrable (with help from deep windows and surround-view cameras), it weights up nicely and consistently at speed without ever feeling too heavy, and provides just enough road grip and feedback so you can confidently push on knowing what the front wheels are doing. That’s all you can ask for in a family SUV.

Plus, the advanced driver-assist safety (ADAS) tech is pretty reigned in most times, only making itself unwelcome with occasional lane-keep assist wheel-tugging and drowsy-driver alert paranoia.

Thankfully, a quick swipe up on the multimedia screen will extinguish these and others quickly. 

Now, there’s a bit of body lean if you want to make your occupants car sick through tight corners, but a bigger problem is the Actyon’s busy/bouncy ride on anything other than smooth roads.

Blame the lack of suspension travel and standard 20-inch wheels, because they do not absorb enough of the bad stuff. 

It’s worse with one person, and the ride improves with more bodies on board, but a recalibration and perhaps smaller alloys or adaptive dampers need to be on KGM’s to-do list. It’s the only dynamic blot. Our advice is to try this on your regular commute route before you buy.

Speaking of blotting things out, the Michelin tyres’ noise-reduction abilities seem to work, and impressively at times, though adding the missing rear luggage cover might be a more-effective sound barrier over Australian coarse bitumen highways.

Still, the Actyon is neither dull nor tiring to drive. And for a new brand offering a value SUV challenger proposition, that’s better than most nowadays. 

And speaking of challenging, how does the KGM newcomer behave in independent crash testing?  

We can’t tell you, because at the time of recording, no results had been released. So, there is no ANCAP rating.

But the KGM looks like it can deliver the goods, offering a host of advanced driver-assist safety systems, including AEB, blind-spot warning, lane-keep assist and rear cross-traffic alert. And it's worth noting this tech is mercifully unintrusive (see the Driving section).

Eight airbags are also fitted (including a front-centre and full head/curtain coverage), along with adaptive cruise control, high-beam assist, front and rear parking sensors, tyre pressure monitors and LED daytime running lights.

Last, but not least, a pair of ISOFIX child-seat latch points and a trio of hooks for tether straps are fitted across the rear seat.

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.

Owners also experience the peace of mind of a seven-year/unlimited kilometre warranty, as well five years of roadside assistance, which is better than most rivals in 2025.

Service intervals are at every 12 months or 15,000km, with alternating capped pricing of $338 or $442 per annum for the duration of those seven years.

Clearly, with such a competitive aftersales program, KGM is gunning for a firmer foothold in the most fiercely fought family SUV segment in Australia.
