Volvo XC90 vs Mercedes-Benz GLS-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.

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

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.

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

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.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

Our Polar White test vehicle, which is the base grade in the three-tiered GLS range, comes standard with a 3.0-litre inline six-cylinder turbocharged diesel engine with 48V mild hybrid technology, nine-speed automatic transmission, permanent all-wheel drive and active air suspension for a list price of $189,100.

This pricing is higher than comparative entry-level grades offered by the two marques which dominate sales leadership in this segment, comprising the BMW X7 xDrive40d M Sport ($179,500) and Lexus LX500d AWD ($158,700).

The GLS450d’s standard features include 22-inch AMG alloy wheels with Continental 325/40 R22 tyres and a collapsible spare, ‘AMG Line’ body styling enhancements, aluminium-look illuminated side-steps with non-slip rubber studs, multi-beam LED headlights and more.

Step inside the keyless interior and you’ll find ‘Hey Mercedes’ voice activation, fingerprint scanner (which memorises individual comfort settings for up to seven users), panoramic sunroof, heat-insulating dark-tinted rear privacy glass and the ‘Premium Plus Package’ that includes heating/cooling for the front seats, heated rear seats, head-up display, separate front/rear climate control zones, heated cupholders and more.

There’s also a concert hall-like Burmester surround sound system controlled by a central touchscreen with digital radio and Apple CarPlay and Android Auto connectivity, plus wireless phone charging, multifunction Nappa leather sports steering wheel and USB ports front and rear.

Driver assistance includes the ‘Parking Package’ (360-degree camera, active parking assist and transparent bonnet), ‘Mirror Package’ (auto-dipping rear-view mirror and electric folding door mirrors with puddle lamp projection of the brand logo) and ‘Driver Assistance Package’ (blind-spot assist, exit warning, speed sign recognition, lane keeping etc) all included as standard equipment.

Of course, Mercedes-Benz offers numerous extra-cost options including a 3500kg towing package plus interior, exterior, suspension and wheel enhancements (including Nappa leather trim) for those who want their GLS with the lot, which can easily push the list price beyond $200K.

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.

The GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

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-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

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.

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

The GLS does not have an ANCAP rating as it’s yet to be tested, but comes standard with a suite of passive and active safety features including nine airbags, auto emergency braking (AEB) with pedestrian detection and junction assist, blind-spot monitoring, traffic sign recognition, head-up display, rear cross-traffic alert, lane-keeping, adaptive cruise control with ‘distance assist’ (autonomously brakes/accelerates in heavy traffic), front/rear parking sensors, 360-degree camera and more.

There’s also two ISOFIX and three top-tether child seat anchorages in the second row, plus two more of each in the third.

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 GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.
