Mercedes-Benz A45 vs Kgm Actyon

What's the difference?

The Mercedes-AMG A 45 4Matic+ may have grown up a bit in that it’s not as noisy or uncomfortable as the first-generation version which arrived in 2013, But if anything, its more portent than ever. Superb Mercedes-AMG craftmanship, outstanding performance and good value as far as bang for your buck goes.

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.

When I went to pick up the Mercedes-AMG A 45 S 4Matic+ I walked right past it and then like that lost and confused John Travolta in Pulp Fiction internet memes, wandered around before asking where the car was.

That’s because I was looking for something with a gigantic spoiler on the roof and probably hi-vis green with stripes. But the car assigned to me was the A 45 S in its standard form, and the styling is subtle enough for it disappear into a crowded car park like James Bond into a lavish dinner party.

But like Bond, chances are the A 45 S is the most hardcore person in the room, it just doesn’t walk in announcing it to everybody.

Look closely and you'll see that the A 45 S is not just another small prestige car. There’s the 90mm quad exhaust poking out of the chunky diffuser, the giant 'Panamericana' grille, and the angry looking front apron.

Then, there are the 19-inch matt black alloy wheels wrapped in low-profile Michelin rubber and enormous brake discs with their red calipers, all barely contained by the pumped up front wheel guards which are much bigger than those on a regular A-Class.

The cost option my test car wore was the 'Mountain Grey Metallic' paint, but if anything it made the A 45 look even more covert.

The cabin is small but luxurious and sporty with two-tone leather upholstery (the red and black 'Lugano' leather in my test car is a no-cost option), there’s the microfibre-clad AMG steering wheel, brushed aluminium trim, metal-trimmed pedals and the large display panel (it’s actually two screens joined) is also standard.

The A 45 S is a hatchback measuring 4445mm in length, 1850mm wide and 1412mm tall. Not keen on a hatch but want something with similar dimensions? The CLA 45 S is the A 45 S’s four-door twin-under-the-skin and is just as much of a weapon.

And if you want your A 45 S to look more aggressive, you can option the 'AMG Aero Package' which will see a giant rear wing fitted to the roof.

Or you can buy the Edition 1 version of the A 45 S which includes the big spoiler and shouty design bits to makes sure everybody knows you’re the assassin in the room.

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.

Along with good performance and handling, part of the appeal of hot hatches is that they’re practical… to a degree. The A 45 S is a small car, but it has four doors, five seats and a boot.

The cabin is small, no doubt about it, but even at 191cm tall I had plenty of room while driving, the seating position is perfect actually, although sitting behind my driving position saw my knees just touching the seat back.

Headroom is getting limited back there, but I still had space. Could you get away with the A 45 S as a family car? I had my family in it for a while, but there’s just the three of us and my son is pre-school-aged. So, a young, small family, yes… until it starts to grow.

Cabin storage is good with two cupholders in the rear centre fold-down armrest along with small door pockets and seat-back nets. Up front there are another two cupholders, giant door pockets, a big split-opening centre console bin and a tray for the wireless charger big enough to fit an iPhone 11 Pro Max.   

Boot space is good at 370 litres. The big shiny CarsGuide suitcase fitted in easily (see images) and apart from the wide-opening of the boot, another hatch power of practicality is that you can fold the rear seats down to open up more cargo carrying space, and in the A 45 S’s case that’s 1210 litres.

I’ve mentioned the wireless charger but there are also four USB-C ports (two up front and two in the rear), back seat passengers also have directional air vents, which is another bonus, along with dark tinted windows (welcome when my son was sitting back there in his car seat).

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.

There may be hot hatches out there which look wilder than the Mercedes-AMG A 45 S 4Matic+ but do they have the most powerful four-cylinder engine ever to go into a mass-produced car? Nope, but the A45 does: it’s a 310kW/500Nm turbo-petrol four.

It doesn’t sound as angry and gravelly as the previous A 45’s engine but it has more grunt (an extra 30kW/25Nm) and is claimed to catapult the hatch from 0-100km/h in 3.9 seconds.

The '4Matic' part of the name indicates the hatch is all-wheel drive and the '+' means it’s a more sophisticated version of the system which allows all of the drive to be sent to one axle, if need be.

What need would that be? The need to drift, of course, which should be up there with other human rights such as clean air, fresh water and free speech.

Yep, the A 45 S comes with 'Drift Mode' (for the racetrack, of course), along with a 'Launch Mode' for perfect-every-time transitions to warp speed.

Changing gears gunslinger-fast is an eight-speed dual-clutch automatic transmission.

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.

Mercedes-AMG says the 2.0-litre, turbo-petrol, four-cylinder in the A 45 S should use 8.9L/100km after a combination of open and urban driving.

My fuel test saw me drive 131km of urban and country roads, plus some motorway sections, and needed 16.9L of premium unleaded petrol to fill the 51-litre tank back to full.

That comes to 12.9L/100km, which is thirsty, but my driving style may have contributed significantly to that high figure.

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.

I wasn’t lying in the introduction to this review. The previous A45 was a pretty intense driving experience. The ride felt brutal, the exhaust note screamed and crackled like somebody had set a wheelie bin full of fireworks alight.

And then there was the sweating. I seemed to sweat a lot driving it and there was nothing wrong with the climate control, that just happens to me when I’m under pressure and excited.

So, has the new-generation A 45 S 4Matic+ gone all soft and quiet on us? No, but things have been toned down a tad.

The exhaust note is not as gruff or loud, and even in 'Sport +' and 'Race' mode it’s still quiet enough to pull into a driveway at night without making enemies of your neighbours.

And the ride is also not as harsh, although even in 'Comfort' mode my wife still found it verging on too firm.

The performance and dynamics, however, felt as sharp as ever.

Acceleration is supercar quick at 3.9 seconds. My gawd, you needed a Ferrari F40 to do that in the mid-’80s, and even now the new Mercedes-AMG GT S supercar gets there only a tenth of a second earlier, and it has a twin-turbo V8.

Top speed for the A 45 S is electronically limited to 270km/h. But hot hatches aren’t really about straight-line speed, they’re more about bent-line speed. You know, corners.

So, I took the A 45 S on the twisty roads I take anything that calls itself sporty. The agility of the A 45 S is outstanding thanks to a rigid chassis that handles a change in direction as quickly and easily as you can turn your head.

The brakes bite hard when they have to, and the all-wheel drive hatch scrambles tenaciously out of corners.

A racetrack is really the best place to truly test a serious sports car's limits and our own James Cleary did just that when he drove the A 45 S at its international launch.

As a daily driver, though, for somebody who occasionally likes to get into it on a curvy road the A 45 S is comfortable enough to live with, but hard enough to remain engaging and dynamic when you get the chance to have a squirt.

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.

The Mercedes-AMG A 45 S 4Matic+ is covered by a five-year/unlimited kilometre warranty.

Servicing is recommended at 12 month/20,000km intervals. Servicing is capped at $850 for the first year’s visit, $1200 for the next and $1600 for the third.

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.
