Mercedes-Benz GLC-Class vs Mazda CX-5

What's the difference?

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.

The Mazda CX-5 Evolve kicks some goals and with its comfortable on-road handling, robust safety equipment and practical interior, it’s still a solid choice for families looking for a mid-sized SUV. The only thing it’s missing is a hybrid powertrain, which would make this already well-rounded package even more compelling.

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.

The next-generation Mazda CX-5 is bigger than before, but it retains the sleek body lines and understated styling that have made it such a handsome SUV. The wider front end and repositioned grille give it a more purposeful look than the outgoing model, while the 17-inch alloy wheels keep things suitably restrained.

Inside, the cabin doesn’t feel too basic despite the cloth upholstery. There are plenty of soft-touch materials, a pleasant dashboard and some new technology, including the 12.9-inch multimedia display. You lose most of the physical buttons, though, so there’s a little less of that traditional Mazda tactility.

The fabric seats are cosy and the extra interior space is definitely noticeable. Overall, there is still an understated elegance to the CX-5’s cabin.

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 front seats are a particularly comfortable place to spend time, with wide seat bases and plenty of elbow room. Getting in and out is easy thanks to the wide door apertures and 205mm of ground clearance and there’s enough space to settle in for a longer journey.

There’s also plenty of useful storage up front, including a large glove box, dual-opening centre console, cupholders and bottle holders, plus a dedicated phone tray with wireless charging. You get a 12-volt socket and two USB-C ports for keeping everything else topped up.

The 12.9-inch multimedia screen replaces Mazda’s familiar rotary selector with touchscreen operation, which I find easier to use. The updated operating system takes a little while to get your head around and there’s no native sat nav, but otherwise it feels functional and fresh for the new-generation model. Wireless Apple CarPlay and Android Auto are standard, with CarPlay maintaining a solid connection throughout my week.

The extra size of this next-generation model is more noticeable in the back, where improved leg- and headroom is good news for taller adults on longer trips. The rear doors open to almost 90 degrees, making it easier to access the ISOFIX child-seat mounts and three top-tether anchor points.

There’s not a huge amount of extra family-focused kit back in the rear row, but you do get directional air vents, storage bins in each door and a centre armrest with cupholders. My nine-year-old was comfortable, although he did point out the lack of a charging port during a road trip.

And, as a parent, I had one other gripe: keeping the fabric seats clean from my kid’s shoes in rainy weather. Let’s just say some seat covers might be a worthwhile investment.

The boot offers up to 466L with all seats in use. That’s not the largest capacity in the class, but it was more than enough for my little family of three this week. I like the level loading floor, although the boot itself is quite tall, which can make lifting heavier items in and out a little awkward.

I’m also pleased to see a spare tyre, even if it is only a space-saver. And while a powered tailgate would be handy, at this price point I don’t think you’ll really miss it... until you’re standing there with your hands full!

There are five variants available for the third-generation Mazda CX-5, and we’re in the second-from-base Evolve grade for this review. It has a competitive $42,990, before on-road costs price, which puts it neatly among its key rivals. The Hyundai Tucson Hybrid starts at $42,850, while the Kia Sportage SX+ petrol begins at $45,580 and the Toyota RAV4 GX 2WD Hybrid at $45,990, all before on-road costs.

On price alone, the CX-5 looks well placed. But there’s one notable difference - all three rivals offer hybrid powertrains in their respective ranges, while the CX-5 currently does not. And as hybrid power becomes increasingly common in this segment, that omission could prove harder for Mazda to overlook.

The Evolve grade enjoys some solid features though, including:

• Heated front seats
• 12.9-inch multimedia touchscreen
• 10.25-inch digital instrument cluster
• Wireless Apple CarPlay/Android Auto
• Bluetooth
• AM/FM/digital radio
• Leather steering wheel
• Dual-zone climate control
• Two 12-volt sockets
• Wired/wireless phone charging
• Cloth seats
• Keyless entry
• Keyless start
• Rain-sensing wipers
• Electric/auto-folding side mirrors
• LED headlights
• LED DRLs
• Reversing camera

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 CX-5 is all-wheel drive and powered by a 2.5-litre four-cylinder petrol engine producing 132kW of power and 242Nm of torque. It has a braked towing capacity of up to 1800kg, giving you the option of some light towing on the weekends, while the six-speed automatic transmission shifts smoothly through its gears.

But there’s no escaping the fact that most of its key rivals now offer hybrid powertrains, and you can feel the absence of one here. The CX-5’s petrol engine is perfectly capable, but it doesn’t have the same efficiency advantage that many buyers in this segment are increasingly looking for.

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.

The CX-5 has a 58-litre fuel tank and claimed combined cycle (urban/extra-urban) fuel consumption of 7.4L/100km, giving it a theoretical driving range of up to 783km. That’s a solid range for a family-sized SUV and means you won’t be constantly thinking about your next fuel stop.

My real-world fuel use settled at 7.8L/100km after a week of longer highway stints and urban trawls, so it’s not too far off Mazda’s official number.

Still, this is where I’d like to see a hybrid powertrain join the CX-5 range. The fuel economy is reasonable, but with so many rivals now offering hybrid options, Mazda is starting to leave some efficiency gains on the table.

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 CX-5 feels composed around town, with power delivered smoothly for everyday driving. But when you need to punch it off the mark, there’s some noticeable lag, and you have to work the engine harder to find the power when tackling a steeper hill at higher speeds. It’s capable enough, but it can feel like you’re asking a little more of it than you should.

The suspension has a firm edge to it, but I like how responsive the steering feels. The CX-5 is genuinely enjoyable through corners, with a dynamic feel and very little body roll.

The cabin is also impressively quiet, with minimal road or wind noise creeping in at higher speeds. Visibility is good through the front and sides, although the A-pillar can get in the way at times.

The reversing camera provides a clear view, while front and rear parking sensors make manoeuvring easier. Overall, it’s not a difficult SUV to park, despite its larger dimensions.

The Mazda CX-5 has a maximum five-star ANCAP safety rating from testing conducted in 2025, with strong results across all four assessment categories.

It scored 90 per cent for adult occupant protection, 91 per cent for child occupant protection, 93 per cent for vulnerable road user protection and 87 per cent for its safety assist systems.

Other equipment include:

• 10 airbags
• Blind-spot monitoring
• ISOFIX child seat mounts
• Three top-tether anchor points
• Driver attention alert
• Driver monitoring
• Front collision warning
• Front cross-traffic alert
• Lane departure alert
• Lane keeping aid
• Rear cross-traffic alert
• Reversing camera
• Traffic sign recognition
• Autonomous emergency braking (AEB) - operational from 0-180km/h.

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.

The CX-5 is covered by Mazda’s five-year, unlimited-kilometre warranty, which also includes five years of roadside assistance. It’s a solid offering, although longer warranty terms are becoming increasingly common in this segment.

Servicing is reasonably priced at around $440 per service over seven years, and the intervals are well spaced at every 12 months or 15,000km, whichever comes first. That should make ongoing ownership relatively straightforward for families.
