Volvo XC90 vs Mercedes-Benz GLC-Class

What's the difference?

It’s a credit to Volvo that the XC90 feels like a new car, even with its older underpinnings. This latest update has successfully addressed areas that needed the most attention, namely the multimedia system, interior and exterior design. The electric driving range now feels somewhat old school compared to the numbers some manufacturers can achieve these days. A lot of PHEVs now exceed 100km EV range and buyers are starting to expect that. And setting up the third row takes way too much effort to want to do it regularly. The new Volvo XC90 is a comfortable, engaging and properly premium family SUV and the updates have only improved what was already a solid offering.

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.

Back in early 2015, I attended the international launch of the second-generation Volvo XC90. At the time I thought it was a handsome SUV, with Volvo successfully interpreting what is essentially a big people-hauling box on wheels with typical Scandinavian flair.

There’s been a facelift since then, but this latest refresh brings the XC90 bang up to date.

New elements include a modern take on the 'Thor's Hammer' LED headlights, and a new bonnet and grille with an updated diagonal logo spread across the car's face. At the rear the only change is slightly darker tail-lights.

The new grille in particular looks great, and with all of the blacked-out elements of the T8 - grille, lower air intakes, parts of the apron, mirror caps, roof rails and window surrounds - it looks quite cool, especially contrasted with the test car's 'Crystal White' paint. It has elevated the overall look.

Inside, Volvo has made big changes, mostly with the dash and console. It retains the familiarity of other Volvos, but is much more in keeping with its new all-electric EX90 sibling.

It still has a horizontal theme, but with cool new vertical air vents. The new multimedia screen fits well into the dash layout, and isn’t over sized. It’s the ideal size at 11.2 inches. There are a few buttons underneath but not many.

The mix of materials used at the front of the cabin includes ‘Grey Ash’ wood, piano black, chrome, metal-look speakers, grey fabric and soft touch as well as hard plastics. It sounds like it would be too much but it works well.

Volvo has always been a leader when it comes to car seats and the new XC90 is no exception. The beautifully designed ventilated charcoal Nappa leather seats look and feel stunning. The tiny Swedish flag is a nice touch, too.

The engine start/stop button and the crystal selector add a touch of glamour to the cabin. Overall, the XC90 feels properly premium inside, still with a Scandinavian bent. Just lovely.

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.

Any dedicated seven-seat family SUV needs to nail practicality and when it comes to the Volvo XC90, there are clear pros and some surprising cons.

One of the many pros is the seats. As mentioned, they look schmick, but are also supremely comfortable and offer the perfect level of bolstering and support. The T8 has a seat adjustment memory function that can be programmed into the driver profiles that also tailors other functions to suit different drivers.

The quality of the materials and build quality of the cabin is largely impressive. Even the damping of the indicator stalk has a feeling of high-end quality.

Volvo’s digital instrument cluster is clear and easy to navigate, once you work out what the buttons on the steering wheel do. They don’t have words on them so it takes a while. The driver’s manual comes in handy for this.

The big story in the cabin is the new 11.2-inch multimedia display. Volvo uses a Google platform and the car comes with Google Services which includes Google Assistant voice control, Maps and Play.

I’m a fan of Apple CarPlay and once I have assessed a car’s in-house multimedia system I often defer to CarPlay. It’s simple and familiar. But aside from using CarPlay to connect once, I used Volvo’s system for the vast majority of my time with this car.

Logging into your Google account means your favourites come up on the map and there is no downside to functionality. If I had the car for longer I would've added Spotify to the system and logged into that, too, but I was happy listening to digital radio on the phenomenal 19-speaker Bowers & Wilkins sound system.

The screen takes some familiarisation, but once you understand the home keys and how to switch between apps, it’s a pleasure to use. It has a clear layout, nice graphics and is responsive. Yes, the air con controls are mostly housed in the screen, but if you tap the lower part of the screen the entire climate menu appears. It is light years ahead of Volvo’s previous screen set-up.

Most functions are housed in the screen, although there are buttons just under the screen for volume and audio on/off, front and rear demisters, hazard lights and a button to open the glove box.

Storage up front is just okay. The console houses shallow cupholders and a handy upright phone holder, as well as the device charging pad. It’s a shame there’s no under console storage, but the transmission tunnel might be too chunky for that.

The shallow central bin houses two USB-C ports and a 12-volt outlet. Bottle storage is decent in the front door cards.

The panoramic sunroof only has a sheer blind (it’s powered) which is less than ideal in a country like Australia. It’s been fine in winter but I’m curious to know what it’s like in the height of summer.

The second row features manual window blinds to keep your little ones cool.

There’s some back support for the second-row seats but the base is flat. Some of the seat fabric in that row looks like it doesn’t quite fit, but I think that’s the nature of the leather with the intricate designs.

In terms of space, there’s ample leg, toe and headroom, and the rear backrests recline for extra comfort on long trips. The bases roll forward and back and the seats are split 40/20/40.

Kids will likely fight over who has to sit in the middle seat because the combination of an intrusive transmission tunnel and the rear of the front centre console protruding into the space means it is not a great seat.

Occupants have access to chest and knee-level air vents, heated seat and digital climate controls, map pockets, two USB-C ports and a central fold-down armrest with a fiddly cupholder mechanism. The rear doors will only house small, narrow bottles.

Accessing the third row of the Volvo is challenging. For starters, to move the second row seats forward you need to use the lever at the top of the seat and the roller under the base to move them. And they are heavy seats. That leaves just enough of an aperture to get into the third row.

But first you have to raise the third row. Sadly there’s no lever in the boot area to quickly raise or lower the third-row seats. You have to either climb into the boot and reach for the lever at the top of the seats, or reach through the back door and try and raise them that way. And again, they are heavy.

It is a deeply unintuitive system and leaves you exhausted and frustrated. Especially when you consider other seven seaters have a much more functional and lightweight third-row arrangement.

Once in the third row, it’s clear it is for humans with tiny legs only. It is not a space appropriate for six-foot tall men like me, even for short distances. You do get ample headroom, air vents, cupholders and storage boxes on either side that open up to show a kid-friendly spider web design with a friendly looking spider. Cute!

The seats fold flat into the boot floor and the loading lip is level with the floor so loading heavy or long items should be a breeze. You can adjust the air suspension from the boot to lower the height further which is always a handy feature.

It comes with a solid cargo blind but you need to remove it if you want to raise the third row. When putting it back in, it catches on the third-row seat belts, so it’s not the best design.

In terms of boot features, the Volvo comes with a household charging cable that is housed neatly under the boot floor in a stylish bag. Many PHEVs and EVs still don’t have a dedicated spot to house a cable so you have to take up boot space with a chunky cable bag. Good job, Volvo.

It has a powered tailgate, a few nooks and a pair of 5.0kg hooks. However, it doesn’t have a spare wheel of any description. Just a tyre repair kit. This is due to packaging restrictions, but it’s never an ideal solution.

In terms of space, the Volvo can swallow 640 litres of cargo with the second row up and 301L with all three rows in place. That latter figure isn’t bad compared to some seven-seaters.

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.

Two powertrains are available in the new XC90, both with all-wheel drive.

The B5 Bright comes with a 2.0-litre four-cylinder turbo-petrol engine with 48-volt mild hybrid assistance offering 183kW of power and 350Nm of torque. It can dash from zero to 100km/h in 7.7 seconds.

The version I’m testing has a 233kW, 2.0-litre four-cylinder turbo-petrol engine with a plug-in hybrid system that uses a 107kW electric motor and an 18.8kWh, 400-volt battery.

The total system output for the T8 PHEV is 340kW and a meaty 709Nm. It uses an eight-speed automatic transmission. It can complete the 0-100km/h sprint in a brisk 5.3 seconds.

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 mild-hybrid XC90 B5 Bright has an official fuel use figure of 8.1 litres per 100 kilometres, which is on the thirsty side, although it is a 2.5-tonne SUV.

Officially, the XC90 T8 Plug In Hybrid sips just 1.8L/100km on the combined (urban/extra-urban) cycle, but as with any PHEVs, unless you charge your car religiously and never drive far enough to deplete the battery, that figure is extremely hard to achieve.

I charged the car regularly using my home wall charger (two to three hours for a full charge) and the fuel gauge barely moved.

After a week of mixed driving my final fuel economy figure was 3.4 litres per 100km, which isn’t too bad.

The XC90 T8 has a 3.6kW onboard charger and a Type 2 plug so it’s only capable of AC charging. It is not compatible with a DC source so no fast charging on the go.

The official electric driving range according to Volvo is 77km, which feels a little old school compared to the many PHEVs landing on the market now that have an EV driving range in excess of 100km.

The offical figure also seems somewhat optimistic because the most I got on a full charge was 60km. Anecdotally, I have heard it can get up to 70km after a charge, it just didn't get there in my time with the XC90.

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.

For a tall, large and heavy SUV, the XC90 has an excellent driving position. You feel hunkered down in the driver’s seat; it’s almost sporty!

Those healthy power and torque figures translate well on the road. It is properly quick off the mark and picks up pace rapidly when already at speed. You do need to work out the trigger point for the accelerator because if you give it too much it feels a little like a slingshot.

The transition between the electric motor and the petrol engine is noticeable, but it’s still smooth. It’s not harsh or clunky like some hybrids and PHEVs. Similarly, the eight-speed transmission is so smooth it rarely makes its presence felt. It's a lovely match for this powertrain.

On that, the cabin is incredibly well insulated. It’s a hushed ride at any speed. Again, you’ll hear the engine kick in but it has a nice note so that noise is welcome.

The powertrain has several driving modes including 'Pure' (EV only), 'Power' (for added performance) and 'Hybrid'. Hybrid is the go-to and 'Auto' allows the system to determine when the petrol engine kicks in. This is the best everyday mode.

Volvo understands the XC90 is more than just family transport and has engineered it in such a way that it offers a surprising level of dynamism.

It’s flatter in corners and bends than you expect of a car of this size and weight. It has a balanced chassis, likely helped by the air suspension, with minimal body roll and little lateral movement inside. Impressive.

It has enough grip on looser surfaces, aided by the all-wheel drive set-up.

The ride quality is more composed and refined at higher speeds, regardless of the road conditions, managing potholes and the like quite well. Volvo has tweaked the suspension tune as part of the update for this very reason.

At lower urban speeds, it’s not quite as calm. You’ll feel speed bumps and potholes and it's a little jiggly on rough surfaces. The low profile (275/35 R22) tyres are partly to blame here.

With that said, it’s not enough to dampen the overall XC90 drive experience. It is a lovely car to drive, whether cruising on freeways, country road blasts or city commuting.

Its underpinnings might be 10 years old, but the XC90 feels as fresh to drive as many of its rivals.

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.

The XC90 is covered by Volvo’s five-year, unlimited kilometre warranty, and the servicing schedule is every 12 months or 15,000km, whichever comes first. These are similar terms to other premium brands in Australia.

Buyers can opt for one of two capped-price servicing packs, costing $2380 for three years and $3870 for five years.

This pricing is a little more than the BMW X5 but quite a bit more affordable than the Mercedes-Benz GLE.

The Swedish brand used to have a reputation for over-priced servicing but it’s sharpened up its offer considerably in recent years.

Volvo has around 40 dealerships located across Australia and conducts its servicing in-house at the dealer.

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.
