Mercedes-Benz GLC-Class vs Volvo XC60

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The Volvo XC60 Ultimate B5 Bright is a fine example of a family car that actually caters to families. There are plenty of practical features inside to help everyday living and it has a good amount of occupant and boot space for the class. I like how it handles on the road and its running costs are reasonable for a luxury SUV. It's not as flashy as its rivals but it's still stylish.

My husband and son spent a lot of time in the XC60 and they have enjoyed a high-level of comfort on our journeys together. We all love the built-in booster seats in the back row because of the independence they offer.

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 XC60 looks mature and graceful with its wide stance and well-proportioned body. The pronounced bonnet and stylish grille confirm its luxury SUV credentials.

The LED headlight design has been inspired by ‘Thor's Hammer’ (gotta love that Scandi heritage!) and the chrome accents around the windows accentuate the optioned darker tint.

Despite having a stately kerb-side presence, it’s not a boring looking car. The 20-inch dual-coloured alloy wheels and sleek body panelling help the XC60 appear almost sporty. Overall, its exterior design looks like it will age well.

The interior style of the XC60 can be summed up in two words - understated elegance.

The cabin isn't as flashy or wowing as some of its rivals and that might be because it lacks the visual impact of customisable ambient lighting, or because the chunkier dashboard looks more solid and dependable than sleek and fancy.

Regardless, the high-quality leather-accented upholstery and trim options elevate the space to earn the 'luxury' tag.

There is a plethora of soft-touchpoints throughout the car and visual highlights like chrome accents, an illuminated crystal shifter by Orrefors and a solid-feeling steering wheel.

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.

Families will appreciate the XC60's cabin. Both rows of seating are roomy for the class and the front seats are supportive and comfortable with multiple adjustments available.

However, there is an electric toggle dial that controls the lumbar-, side-, and under-thigh supports as well as the massage function, but flipping between modes can be a bit confusing at first.

I enjoy having the practical two-position memory function on both front seats, as I’ve been travelling a lot with my husband and the heat/ventilation features on the front seats have been great during a recent run of strange weather.

The back seats are well-cushioned and the bench is wide with three adults being able to sit without too many grumbles. 

I have plenty of room for my 168cm height and my seven-year old is able to get in and out without any trouble thanks to the higher ground clearance.

Our absolute favourite feature is built-in child booster cushions in the outboard seats. They have two height positions to accommodate different heights/weights and it’s been wonderful for my son to have the autonomy of buckling himself in. But also just awesome for my husband and I because it’s one less thing to think about! 

Storage throughout the car is good for the class with the front enjoying a mid-sized middle console, large glove box, two cupholders and two large drink bottle holders. The extra-large storage bins in the front doors are also very handy. 

In the rear, you have two retractable cupholders in the fold-down armrest, two map pockets and two drink bottle holders in each door.

The other amenities are great with the individual climate control and four sets of directional air vents – ideally located on the back of the centre console and on the B-pillars. 

Charging options are solid with both rows enjoying two USB-C ports and the front also getting a 12-volt outlet and wireless charging pad. The boot has a 12-volt socket, too.

Onto the other technology, the 9.0-inch touchscreen multimedia system is responsive and relatively easy to get around once you spend some time with it. Along with the Google subscription, you also get wired Apple CarPlay and Android Auto. 

The 12.3-inch digital instrument cluster shows the navigation map and the head-up display incorporates directions, which is great.

The cluster itself isn’t customisable, though, and I like fiddling with things like that to personalise the driving experience.

Another practical feature is a secondary key fob which can be programmed to control the maximum speed the car can travel and the audio volume.

I'm sure this would be handy for parents of any P-platers out there who often borrow the family car.

The key fobs are easily distinguishable. too. The spare for our test vehicle is a bright orange colour, so there are no 'whoops, I grabbed the wrong key' arguments, either.

The boot space is a great size at 483L offering plenty of room for holiday luggage. The back seat has a 60/40 split and a ski-port to open up storage options.

The loading space is level and there is a temporary spare tyre underneath the floor. You can adjust the height of the car using the air suspension and I love a powered tailgate.

There are four variants for the XC60, split evenly between the B5 petrol engine and the T8 plug-in hybrid. Our test vehicle is the top-spec Ultimate grade coupled with the B5 petrol engine.

Without any packages, this combination will cost $80,990, before on road costs, which is a $1000 price hike for the 2024 model year.

The standard features list for the XC60 is robust and there are some great premium features, like the electric and heated front seats that feature electrically adjustable under-thigh support, lumbar support and side-bolster support.

The front seats also have a two-position memory function, which I find helpful whenever I share the driving with my husband as there is no hassle for me to get back to a comfy driving position after he drives! 

Other premium features include a heated steering wheel, pre-entry climate control (perfect for those super-hot days), premium leather-accented and high-quality trims to choose from.

The technology highlights include a complimentary four-year subscription for the built-in Google Assistant, Google Maps and Google Play Store which are accessed via the portrait-style 9.0-inch touchscreen multimedia system.

There is a 12.3-inch digital instrument cluster, wired Apple CarPlay and Android Auto and a very handy four-zone climate control system.

Other practical features include a handsfree powered tailgate, keyless entry, keyless start, coloured head-up display and a ticket holder on the windscreen, for those odd occasions where you have a physical ticket!

Now, here come the optional packs our model has been fitted with. There’s the 'Climate Pack' for $150 that adds headlight cleaners and a 'Lifestyle Pack' for an additional $13,800.

The latter sounds expensive but you get some lovely features in the pack, like a panoramic sunroof, improved Bowers & Wilkins sound system, Nappa leather upholstery, front seat ventilation, front seat massage function, air suspension and tinted rear windows.

Add on $2050 for the 'Thunder Grey' paintwork and it slides in at $96,990, before on-roads. and that places it towards the top-end of the market compared to its rivals, but the BMW X3 xDrive30i M Sport still just beats it with a $97,900 price tag.

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.

Volvo is aiming to offer only fully-electric powertrains from 2026 and the new XC60 B5 petrol variants feature a mild-hybrid element designed to improve fuel economy, especially in stop-start traffic.

Our test vehicle has a 2.0-litre, four-cylinder, turbo-petrol powertrain with a maximum power output of 183kW and 350Nm of torque. It’s an all-wheel drive and has a smooth eight-speed auto transmission.

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 official combined cycle fuel figure is 7.6L/100km and my real-world usage averaged 8.1L/100km.

That’s pretty economical given that I cover a good mix of open road and urban driving and am not precious with the power.

Based on the combined cycle number and the large 71L fuel tank, expect a driving range of around 934km. To give you an idea of time between fills, I drove it for 14 days before having to fill up.

You can’t sneak in any blends or lower grade fuel though as Volvo recommends a minimum 95 RON premium unleaded be used.

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 XC60 is a relaxing car to drive, it does what you expect it to do most of the time. It has enough power to handle open-road touring with ease and while the suspension is on the firmer side, the ride feels well-cushioned.

The only time it skips a beat for me is when you're easing off the accelerator, slowing down, but then need to pick up speed again.

Say, when you find a gap in traffic and begin to merge. There can be a short delay before acceleration happens and it feels somewhat clumsy. But these moments are few and far between.

The cabin is quiet, with minimal wind and road noise. Our family had no issues chatting. It only gets loud inside when heavy rain hits that big panoramic sunroof.

Adaptive steering makes the XC60 feels nimble and horribly tight city streets less daunting. It’s easy to manoeuvre in a small car park, as well.

The clear 360-degree camera system and sensitive front and rear parking sensors also help to make light work of a parking. 

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.

It’s not often common to associate a luxury brand with reasonable on-going costs but the Volvo XC60 is offered with very competitive pricing and terms.

The five-year/unlimited km warranty is normal for the class but you can pre-purchase a three-year/45,000km or a five-year/75,000km servicing plan.

The three-year plan is priced at $1750 (averaging $583 per service) and the five-year plan is priced at $3000 (or an average of $600 per service). Both plans are cheaper than a pay-as-you-go option and are inexpensive compared to some rivals.

Servicing intervals are good at every 12 months or 15,000km, whichever occurs first.
