Suzuki Swift vs Mercedes-Benz GLC-Class

What's the difference?

So, there you have it. A brief look at the new, sixth-gen Swift.

Better where it needs to be, the supermini survivor still remains competitively priced, with loads of new efficiency and safety tech that buyers will appreciate.

But, most of all, the Suzuki still feels, drives and rewards like the old model used to. It just does so with more sophistication.  

As inexpensive city cars continue to fade, the new Swift continues 41 years of providing a fun, affordable and dependable solution, in a vibrant and desirable package.

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

At first glance, the new one looks a lot like the old one. Short overhangs, long wheelbase, upright A-pillars, that signature 'floating' roof. This could be nothing else but a Swift.

Obviously, though, every single panel has changed, resulting in a stronger, quieter and more aerodynamic body.

Helping communicate this is a new and very definite crease line added to create a more-pronounced shoulder. The bonnet seems to be more clamshell-like and the nose is squarer, too. Indeed, everything about the overall styling seems to be more upright.

Debate is already raging in some circles. Is the new Swift too fussy? Too conservative? Has it lost the playful boldness of the proceeding version's gently-sculptured sides and hidden rear-door handles? Are the proportions slightly out now? Has the previous design integrity and oneness of vision been diluted? Does the 2017 predecessor look better?

Underneath, the platform is essentially the same, while overall dimensions are largely identical except for a 20mm stretch and 25mm roof lift. Length, width, height and wheelbase numbers 3860mm, 1735mm, 1520mm and 2450mm, respectively.

Happily, the aesthetic changes inside are likely to please rather than perplex, and even delight rather than divide opinion.

The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

From a packaging perspective, the latest Swift carries on from before, and that’s no bad thing. It remains exceptionally roomy as well as practical.

To that end, entry and egress are easy, there’s a sense of spaciousness thanks to deep windows, a high ceiling and lofty seating, while the latter also helps provide an agreeable driving position. Storage and ventilation are provided in abundance.

For many people, the dash redesign reflects a big change in attitude, having finally grown up and away from the previous cheap and cheerful look. Highlights include pleasing seat fabrics, interesting textures and a sense of quality craftspersonship, within a stylish and sweeping design. After 41 years, the Swift has matured gracefully.

It’s also worth pointing out the super-clear analogue instrumentation dials, supported by a digital speedo and configurable trip computer data; actual buttons for the heating and air-conditioning system and – joy of joys – a handbrake lever.

Plus, if you want to turn off the various beeps from the driver-assist systems, physical buttons are but a simple press away. No distracting sub-menu searches within fiddly touchscreens here, thanks.

Except if you want to change the volume because you’ll need to prod the screen after all. The knob is always the better option, Suzuki.

What else? The rear bench area is a little plain but surprisingly roomy for this class of light car. Probably more so than a Corolla provided back in the early 2000s, with a decent level of cushy support for two people or three at a squeeze.

Given the extra specification, even the cheapest grade is all the Swift you’ll need. A sign of a democratic car.

But keep in mind the base variant no longer comes with a driver’s seat adjuster, passenger vanity mirror and multiple USB ports found in the Plus and GLX versions, while it is alone with a clammy plastic rather than leather-sheathed steering wheel rim.

At least cargo capacity edges up, by 23 litres to 265L (VDA), and that’s just under the luggage cover, thanks to some clever repackaging of a now-lower boot floor and internal tailgate panels. Drop the rear backrests and that expands to 569L.

Note, however, that for the Swift to achieve its sensationally low kerb weight that starts from just 919kg (up around 50kg), it now uses a fiddly and frankly-inadequate tyre repair kit. Thankfully, Suzuki offers that space-saver spare, at extra cost (and mass) of course.

Still, keeping those kilos low pays high dividends when it comes to performance and economy.

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

The power and torque figures aren’t the only numbers that have risen sharply, with the GLC63 clearly impacted by a double whammy of inflation and the usual new-car price rise.

The GLC63 now starts at more than $191,814 for the SUV and $198,415 for the Coupe, which represents a nearly $30k increase over the old V8-powered model, which was priced at $164,600 just two years ago. Even for luxury car buyers that’s a big jump, especially when you’re trying to convince people of the merits of the four-cylinder powertrain. 

That also means it's more expensive than all of its key competitors, including the BMW X3 M Competition, Maserati’s Grecale and the outgoing, petrol-powered Porsche Macan GTS.

To help explain some of this price increase Mercedes-Benz Australia has opted for a high level of standard specification for local cars. Standard equipment includes 21-inch alloys, AMG composite braking, a panoramic sliding sunroof, a unique AMG steering wheel, power-adjustable sports seats in Nappa leather, a head-up display, dual-zone climate control, wireless smartphone charging and a Burmester 3D Sound system.

Also included is the AMG Track Pace suite, for those who want to unleash their GLC on the racetrack.

There’s also a limited run, AMG Edition 1 Package available too, for an additional $12,900. On the outside you get Manufaktur graphite grey magno paint, foiling with colour gradation and large AMG logo on the sides, an AMG Aerodynamics Package, unique alloy wheels with Edition 1 and AMG branding, yellow brake calipers and an AMG fuel filler cap in silver chrome with AMG lettering. 

Inside there’s AMG Performance seats, AMG Nappa leather in black with yellow contrasting stitching, AMG illuminated door sills,  carbon-fibre AMG trim highlights, yellow seat belts and a unique AMG Performance steering wheel wrapped in carbon-fibre and microfibre.

If there’s one area where Suzuki shines, that’s in making sweet little engines, and the new, chain-driven, 1197cc 1.2-litre mild hybrid three-cylinder petrol unit is no exception.

Now, on paper, 61kW at 5700rpm and 112Nm at 4500rpm may seem slightly lacking. A Mazda2 manages to make nearly 35 and 30 per cent more power and torque, respectively.

But the Swift's new 'ISG' integrated starter/generator/electric motor unit delivers an additional 2.3kW and 60Nm.

Combined with the hatchback's comparative lightness, it makes for a sufficient power-to-weight ratio of between 63 and 66kW per tonne.

Or, in other words, it provides some welcome extra low-down muscle.

Drive is naturally sent to the front wheels, via either a light-yet-positive shifting five-speed manual gearbox, or new CVT auto. Both have been heavily revised in their new roles serving the mild-hybrid powertrain.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

The latest Swift’s maturity does not end with its suave cabin presentation.

Prioritising high economy and subsequently low pollution, this Euro 6d-rated three-pot hybrid powertrain promises an astonishing combined fuel-consumption average of just 3.8 litres per 100km for the manual, and slightly more for the CVT at 4.0L/100km.

The results are 78 and 80 grams per kilometre of carbon dioxide emissions, respectively, along with around 970km between refills of the meagre 37L fuel tank.

These facts somewhat ease the pain of the need for more-expensive 95 RON premium unleaded petrol instead of the regular brew. High-tech solutions do require superior fuel, after all.

With just 70km on our ultra-tight test car’s odometer, the trip computer’s 6.7L readout is likely no indicator of the frugality we’re expecting to come.

So, how are such low consumption figures attainable? Along with better aerodynamics and a low kerb weight, the latest Swift Hybrid’s ISG hybrid unit generates supplementary electricity under acceleration, to ease the engine’s reliance on petrol.

It also recharges the 12-volt lithium-ion battery that lives beneath the front passenger-seat floor off-throttle via regenerative braking.

Note that the Suzuki never drives purely on electricity.

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

No Swift since 2004’s new-millennium redesign has been anything less than fun to punt around. A focus on driving pleasure and superior dynamics has helped make each version a cut-above most rivals.

Losing the smooth old 1.2-litre four-cylinder engine in the name of low consumption and emissions is a noble move. But how does this translate out in the real world, especially with a Swift fan behind the wheel?

It's mostly great, actually.

Losing a cylinder results in a slightly less creamy power delivery, especially as it’s accompanied by a distinctive three-cylinder exhaust-note thrum. But that’s still in keeping with the Swift’s endearingly sporty character.

Better still, even with all the examples we tested showing barely more than delivery mileage on the odometer, there seems to be more than enough grunt to please driving enthusiasts.

While not wanting to tax engines that weren’t even run-in yet, the charming revvy eagerness and instant throttle response remains, along with a discernible extra kick when accelerating away from standstill.

Even being so new, our Swifts proved to be lively, lusty and surprisingly rapid performers. We can’t wait to test run-in examples!

The five-speed manual is deliciously well-oiled and precise, immersing the driver into the Swift experience on another level compared to the CVT auto, which still manages to impress by responding quickly and effortlessly, without feeling laggy or droney. A lot like the old version.

Suzuki is making a lot of noise over how agile yet comfortable the newcomer’s handling and ride qualities are, as a result of improved rigidity and noise-dampening measures.

The Swift’s MacPherson-style front struts and torsion beam rear suspension systems have been revised with stronger and quieter mounts for better performance, while the electric steering has been retuned for greater feel and linearity. 

The result? Even our limited time behind the wheel revealed tactile and precise steering, composed handling and extraordinary isolation from the road below for a car barely weighing 950kg (at most).

Combined with the nuanced driver-assist safety tech that rarely interrupted the fun, the latest Swift is a cheerfully animated, nimble and rewarding experience... and one that stands out all the more for evolving while so many other like-minded rivals like the Ford Fiesta have sadly fallen away.

Bravo, Suzuki. Generation Number Six remains the enthusiast driver’s choice, and a hybrid bargain to boot.

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

The GLC63 comes standard with a comprehensive suite of safety features including 'Distronic' (Mercedes’ name for adaptive cruise control), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Traffic Light Assist' and 'Adaptive Highbeam Assist'. It also includes Mercedes’ 'Pre-Safe' accident anticipation system - which pre-tensions the seat belts and will even play a white noise to protect your ears if it senses a crash is imminent.

A parking system that includes a 360-degree camera and active parking assist is also included.

The GLC range was awarded a five-star ANCAP rating in 2022, which pre-dates the latest testing protocols, so doesn’t provide a like-to-like comparison for vehicles tested after that date.

Suzuki offers an industry-average five-year/unlimited kilometre warranty and roadside assistance.

Service intervals are every 12 months or 15,000km, while basic capped-price servicing is available, with the website showing pricing for the first five years and 100,000km averaging $391 per workshop visit.

The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.
