Summary
Volvo XC90
With its new XC90 line Volvo has squashed the stereotype that a luxury seven-seater has to be powered by a lusty V8. We put the hybrid T8 to the test.
We live in a world of stereotypes. All black people can dance, all Asians are good at maths, all Americans are loud and brash. Blondes are dumb, girls are not good at sport, police officers live on doughnuts.
By the same token, BMW drivers don’t know how to use an indicator or read a stop sign, Audi drivers are yuppies, Mercedes drivers are arrogant and stuffy, and Toyota drivers are, well, beige.
Oh, and Volvo drivers are tree-hugging, latte-sipping, doily-loving, hat-wearing geography teachers or dentists who drive boring, conservative cars too slowly in the fast lane, and refuse to let people pass.
Like mud, if you fling stereotypes around often enough, they stick and Volvo has had to work hard here to kill the 'just another Volvo driver' leanings.
It has answered in the best way possible with technically advanced, sharp-looking cars that will continue to be on trend for years to come. With the new XC90 line it has also squashed the stereotype that a luxury seven-seater has to be powered by a lusty V8.
We put the hybrid T8 to the test.

Mercedes-Benz GLS-Class
If you’re in the market for a full-size, seven-seat, luxury SUV you’re obviously living life large. Big family, lots of friends, dogs and cats, and heaps of activity - horses, boats, camping?
You’re not in the BIG big-buck orbit of the Bentley Bentayga, nor are you ready to plug into the electrified matrix with the Tesla Model X.
You’re aiming at a six-figure bullseye between $130,000 and around $150,000. On a three-year novated lease, somewhere around three grand a month.
Which takes in the chunky Lexus LX and German ‘Big Three’ - the Audi Q7, BMW X7, and this car, the new, third-generation, Mercedes-Benz GLS.
Mercedes-Benz Australia invited us to experience the car on a launch drive across city, suburban and rural roads.

Verdict
Volvo XC907.9/10
This hybrid XC90 is on point with all that Volvo’s flagship offering is renowned for – safety, performance, technology and style - and allows you to give impetus to your environmental ideals too.
The D5 Inscription remains my favourite in the new XC90 range because of its overall verve but no doubt the Twin Engines will find equal favour especially amongst buyers who spend a lot of time in traffic covering short distances.
Mercedes-Benz GLS-Class8/10
The new GLS is everything you’d expect of a Mercedes-Benz with an S in its name. Luxury, performance, space, and in this case, thoughtful practicality. A super-capable, super-sized family truckster with the lot.
Design
Volvo XC90
What’s not to love about a large, chunky SUV with a no-nonsense stance and bold demeanour? One where the sloping lines and angles don’t mess with the feeling of understated efficiency and the sizeable grille and 'Thor's hammer' headlights are complementary rather than a distraction?
That quiet confidence is mirrored in the interior space, too, where the minimalist design brief leaves an uncluttered dash and just a couple of buttons to interrupt a smooth and tasteful canvas.
The cabin really is a beautiful place to be with its large digital driver display and, in our test car, a stylish mix of leather, wood and smart plastics proving to be a winning combination.
Supportive, luxurious sport seats whip up the comfort level and electrical adjustment means it is super easy to settle on a suitable driving position.
Not as simple, however, was getting the side mirrors to stay in their set positions, the pesky things assuming a shape shifting personality of sorts every time you switch off the engine. There is evidently some hoodoo combination to get them to behave but as I found with the S90 that particular spell does not feature in my extensive repertoire.
Mercedes-Benz GLS-Class7/10
Launched globally in mid-2019, Merc describes the GLS as the S-Class of SUVs, which is apt given its 5.2m length, 2.5-tonne mass, and ultra-premium specification.
As mentioned, the GLS is big; a step up from the already substantial model it replaces. Built with the US market in mind, in fact it’s produced in Tuscaloosa, Alabama, it’s more than five metres long, close to two metres wide, and over 1.8m tall. And there’s more than three metres between the axles, a 60mm wheelbase increase over the previous model.
And despite the size of the canvas, the Benz design team has managed to make the GLS look like a modern Merc. Signature elements include obvious ones like the slatted grille with a couple of three-pointed stars on the nose.
But there’s also, the carefully chiselled twin ‘power dome’ bonnet, scowling LED headlights and vents to aid front brake cooling and smooth aero performance around the front of the car.
The big beast’s off-road intent is highlighted by extensions around the wheelarches, with big optional 22-inch rims sitting underneath. The fact they look right-sized for the car speaks volumes about its scale.
The racy AMG Line package is standard, and a recess and pronounced character line, tightening the lower waistline is a familiar Merc treatment, plus alloy roof rails toughen the look while dialling up practicality.
The rear is relatively simple, borderline generic, with tapered tail-lights offering the only strong whiff of design personality. But believe it or not, thanks to careful detail sculpting of the body, and smoothing underneath the car it boasts a drag figure of Cd 0.32. Outstanding aero performance for a large SUV.
The driver and front passenger are presented with a sweeping dashboard dominated by twin 12.3-inch digital screens, one primarily covering the instruments, and the central screen managing the MBUX media system, including audio, nav, phone integration, car set-up, and more, plus ‘Hey Mercedes’ voice control.
The overall feel is simple, and restrained, yet massively confident, with a subtle colour palette, large squared-off elements defined by brushed metal finishes, and an obvious, intense attention to detail, from the haptic controls to the beautifully finished, multi-function steering wheel.
And the standard Burmester audio system includes a two-way in-car communication function that subtly amplifies the driver and front passenger’s voices for those in the third row, and vice versa. Sheer genius.
Practicality
Volvo XC90
Seven-seaters are a boon for large and growing families, for people who are often carrying the kids’ friends, or if you just want some extra space. The XC90 has the latter in spades with plenty of room for long legs and big heads although the third row is naturally better suited to children instead of adults.
Comforts back there in the third row include air vents and cup holders as well as decently-shaped seats.
Oh, and much greater odds of being able to gulp down those dodgy marshmallows you found at the bottom of the swimming bag before your mother spots you.
There are similar offerings for passengers in the second row – climate control and storage I mean, not marshmallows – with integrated booster seats and two ISOFIX points also adding shine.
The outer seats in the second row slide forward and tip over to facilitate access to the back while both the second and third rows fold flat, individually if need be, to increase the load compartment.
The boot features a pair of sturdy shopping bag hooks, too, which may not raise an eyebrow in your world but are invaluable if you want to arrive home with the box of eggs intact and not crying over spilt milk.
Mercedes-Benz GLS-Class9/10
Space is obviously a critical factor here, and no surprise there’s copious amounts of it inside the GLS.
Front seat passengers enjoy plenty of breathing room, without feeling remote from one another, and there’s lots of storage in the shape of a large lidded box/armrest between the seats, a decent glove box, two big cupholders and jumbo door pockets with room for large bottles.
There’s one data-enabled USB port in the front, two charge-ports in the second row, and four in the third row. Shouldn’t be any complaints about powering mobiles, tablets or games.
The second row feels every millimetre the SUV limo. Simply getting in and out is made easier because an auto lowering function drops the car 25mm when one of the doors is opened.
I was able to sit behind the driver’s seat set for my 183cm position with heaps of head and legroom on offer. And there’s an extra 10cm of electrically adjustable travel to play with if those in the third row agree.
The fold-down centre armrest features a lidded storage tray and twin pop-out cupholders. There are netted pockets on the front seatbacks, and again, the door bins are big enough for large drink bottles.
Three adults across the rear is a breeze, there’s climate control ventilation, and a huge glass sunroof is standard. Rather than asking ‘Are we there yet?’ the kids will be disappointed when you arrive!
Then there’s what the Cleary family refers to as ‘the way back seat.’ A pair of third row seats for the lucky kids that get to inhabit their own little world. Getting in and out is relatively civilised thanks to electric slide and tilt for the second row seats, and space is generous. I could sit comfortably, so the kids will be all smiles.
With all seats upright cargo capacity is enough for a seven-person day trip (355L VDA). Press the button to fold the 50/50 split-fold third row down and your options expand substantially (890L). And with 40/20/40 split-folding second row lowered, transportation of a full, three-ring circus is on the cards (2400L). Overall, more space than the arch enemy BMW X7.
Plus, the ability to lower the car 50mm thanks to the standard air suspension makes life even easier. And one button lowers the second and third rows at the same time.
The spare is a collapsible space-saver, and towing capacity for a braked trailer is 3500kg, with a tow ball weight of up to 140kg. The ESP system also features a trailer stabilisation function that counters oscillation with “braking intervention.”
Price and features
Volvo XC90
You have a choice of three XC90s – a diesel, petrol and electric/petrol hybrid – each available in three trim levels.
With a price tag over $120,000, our hybrid Inscription will take more than spare change to own but does come with a fairly generous inclusions list.
Standard fare features seven seats, tri-zone climate control, 9.0-inch tablet-style multimedia colour touchscreen with 12.3-inch digital driver display, Bluetooth connectivity, USB ports and 12 volt connections, auto lights and wipers, powered tailgate, reverse camera and sensors and an impressive suite of safety systems.
Our car was also equipped with a $3000 'Technology Pack' (Apple CarPlay, 360-degree camera, head-up display, DAB radio tuner) and the $8000 'Premium Pack' with Bowers & Wilkins audio, air suspension and heated seats for front and middle row passengers.
Am I the only one thinking it's a bit stingy to expect you to hand over more for these features in car that already costs in excess of $100,000?
Mercedes-Benz GLS-Class8/10
The GLS launches in Australia with two models, the turbo-petrol GLS 450 4Matic at $146,500, before on-road costs, and the turbo-diesel GLS 400 d 4Matic at $153,300.
Specification is identical across the two variants, and when you’re competing against the likes of the Lexus LX570, Audi Q7 and BMW X7, as you might expect the list of standard features is lengthy.
Aside from the comprehensive suite of safety tech, covered in the Safety section below, the GLS equipment list includes, 21-inch alloy rims, adaptive high beam assist, air suspension, alloy roof rails, AMG body kit, a huge panoramic sliding glass sunroof, privacy glass from the B-pillar back, auto tailgate, keyless entry and start, rain-sensing wipers, cruise control, LED headlights, and power closing doors.
The power closing doors are a big plus for parents not wanting to disturb kids nodding off in the car, with the soft-touch function drawing the door in for the last few millimetres to an almost silent close.
Inside there’s ambient lighting (64 colours), strategically placed open pore oak wood trim, 13-speaker/590-watt Burmester surround sound audio, electric folding second and third row seats, a head-up display, ‘Mercedes-Benz’ branded illuminated sills, leather seat upholstery (‘Artico’ faux leather on the dash and doors), multi-adjustable electric seats in the front and second row (memory in the front), electrically adjustable steering column, leather-trimmed multi-function steering wheel, and five-zone climate control.
The multi-media system is spectacular, incorporating the twin 12.3-inch digital screens, the central media unit managing nav, digital radio, mobile device connectivity, Apple CarPlay and Android Auto, plus vehicle tracking. There are also remote vehicle status functions (door locking, valet parking, etc), global search (Amazon Alexa, Google Home, Yelp, and Trip Advisor), and a wireless device charging pad.
The basket of goodies can hold its head high in this part of the market, so the value equation stacks up well.
Under the bonnet
Volvo XC90
Naturally, there is much to be said about a V8 engine, as available in previous XC90s; superlatives in the main, but the combination 'twin-charged' four in our T8 is hardly struggling for words of praise either, especially from buyers who are not only environmentally aware but have the means to add action to ideology.
This plug-in hybrid is powered by a supercharged and turbocharged 2.0-litre four-cylinder petrol engine that delivers 235kW/400Nm to the front wheels, blended with a twin-battery 65kW/240Nm electric motor on the rear axle, that improves the economy and range of Volvo’s signature offering.
They can be used alone or in combination, with the torque figures and actual performance varying accordingly. Volvo suggests that on electric power only, you would be good for 30km, perfect for average city commutes, although we couldn’t muster more than 24km during our test week.
A charging connector that suits most household power sockets is a handy advantage, meaning you can recharge in your garage, or at work – anywhere really, that you can sidle up to an electric socket. Charge time is usually around four hours.
The 2.0-litre petrol engine with its turbocharger, and supercharger, and of course superpowers (made that last one up), is a handy unit given the XC90’s bulk, and has a willing accomplice in form of a silky smooth eight-speed transmission.
Mercedes-Benz GLS-Class8/10
There are two engines on offer. The 3.0-litre (M256) in-line six-cylinder turbo-petrol GLS 450 4Matic, and the 2.9-litre (OM656) in-line six-cylinder turbo-diesel GLS 400 d 4Matic.
The all-alloy, twin-scroll single-turbo petrol engine delivers peak power of 270kW from 5500-6100rpm, and maximum torque of 500Nm across a broad plateau from 1600-4500rpm. It also features a 48-volt electrical system driving the ‘EQ Boost’ set-up, able to deliver an extra 16kW/250Nm for short periods. The integrated starter-generator also enables energy recuperation.
Although the all-alloy, twin-turbo diesel features variable valve lift it gives some ground on power, offering up 243kW between 3600-4000rpm, but torque is a solid whack, with 700Nm on tap from 1200-3000rpm. Worth noting, that to minimise emissions this engine features a “selective catalytic reduction converter” in the exhaust, which brings with it the use of an ‘AdBlue’ reducing agent. The separate AdBlue tank has a capacity of 31.6 litres.
The nine-speed auto transmission is the same in both versions, although the diesel has a slightly lower final drive ratio.
Efficiency
Volvo XC90
Well, technically, in automatic hybrid mode you should be, if official figures are to be relied upon, returning figures of 2.1L/100km.
Real life rarely works like that though, with our readings closer to 7.6L/100km. Still credible for a 2.3 tonne SUV, although interestingly, we managed 6.0L/100km in the 2.0-litre diesel.
Mercedes-Benz GLS-Class8/10
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle for the GLS 450 is 9.2L/100km, the more frugal GLS 400 d trimming that to 7.7L/100km. The petrol 450 emits 210g/km of CO2 in the process, the diesel 400d dropping that slightly to 202g/km.
Stop-start is standard, you’re looking at premium unleaded for the 450 GLS, and you’ll need 90 litres of dinosaur juice to full the tank on both models.
Driving
Volvo XC90
Thanks to semi-autonomous technology, this XC90 can pretty much drive itself, although taking your hands off the steering wheel for more than 20 seconds will very quickly remind you of the law.
So, provided you touch the steering at those regular intervals and the road is clearly marked, this car can stay within its lane in city confines, follow confidently behind the car in front, braking, accelerating and stopping when necessary.
It is less confident on narrower poorly marked or inconsistently edged roads, but that doesn’t detract from the wow factor, and in all honesty has more to do with our infrastructure problems than Volvo’s technical wizardry.
The thing is that even though this car can carry out most of the mundane functions of driving, it has such a sense of ease about it that you will want to drive yourself.
In slow, stop-start city commuting the electric engine comes into its own, allowing you to shuffle along without troubling its petrol wing man. You have to remember to recharge when you get to the office or back from the school run, however, or it sort of defeats the purpose.
The petrol unit, with a more than competent eight-speed transmission to facilitate performance, sticks fastidiously to the task, although it can sometimes feel a tad lethargic.
It is hard to find fault with the petrol and electric engines working in unison, a combined peak torque of 640Nm giving you all the oomph you need.
The twin engine XC90 is nicely balanced, easy to manoeuvre and an excellent cruiser. You can occasionally feel its weight around tight corners but that is to be expected.
The brakes took a bit of getting used to as the car initially uses regenerative braking to capture energy, but then stops quickly as speed drops. It's a bit of a surprise, but easy enough to accommodate.
Mercedes-Benz GLS-Class7/10
Merc claims the GLS 450 will sprint from 0-100km/h in 6.2sec, and the 400 d in 6.3sec. Not hanging around for a 2.5 tonne mothership. But the standout is the 400 d’s torque. All 700Nm of it available from just 1200rpm to 3000rpm; right in the mid-range sweet spot.
The nine-speed auto transmission is smooth yet responsive, with paddles on the wheel for manual shifts when you want to pick the ratio. The combination of effortless grunt and the nine-speeder keeping things on the boil is an impressive one.
Suspension is by double wishbones at the front and multi-links at the rear, and while you can feel the weight in cornering, the standard Airmatic air suspension (which does away with steel springs) is superb in terms of ride comfort and body control.
We took a deep breath and pushed enthusiastically through a series of sweeping corners and the fat (285/45 fr - 325/40 rr) Continental ‘PremiumContact 6’ rubber wrapped around our car’s (optional) 22-inch rims gripped hard.
The ‘4Matic’ all-wheel drive system also seamlessly shuffles torque between the front and rear axles (theoretically up to 100 per cent in each direction).
Merc has put extra focus on body rigidity, the tuning of engine and suspension mounts, and sound absorption, and it shows. The GLS 400 d is beautifully refined on the highway. A neat touch is the car automatically lowering 15mm at motorway speeds or when ‘Sport’ mode is selected.
Steering is electromechanically assisted, and Merc says the front suspension geometry has been revised to minimise vibration through the wheel. And yes, feedback is minimal, but unfortunately so is road feel with only a general connection between your hands on the wheel and the front tyres on the bitumen.
When you’re steering a large beast like this, often with something substantial hitched to the back, you want to know braking performance is up to the task, and the GLS’s big ventilated discs all around deliver reassuringly strong stopping power, with nice, progressive pedal feel to boot.
The seats are adjustable six ways to Sunday, but beyond that they’re comfortable and supportive, even over long stints behind the wheel.
We stayed on the bitumen, because, let’s face it, that’s where this car will spend 99.9 per cent of its time, with the exceptions of the boat ramp, a ski weekend or pony club.
For those special occasions the optional ‘Off-road engineering package’ adds a low-range transfer case, inter-axle locking, hill descent control, and under body armour for more serious work.
Safety
Volvo XC90
It is no secret that safety features are one of the foundations of the Volvo ethos. It was after all Volvo engineer Nils Bohlin who invented the three-point seat belt in 1959 which turned out to be the most important safety device ever created.
Instead of cashing in on the patent, and in keeping with their guiding principle of safety, Volvo shared it with other car manufacturers which has of course resulted in untold lives being saved.
This XC90 boasts other marvellous safety inventions, including blind spot monitoring, lane departure warning, AEB, pedestrian detection and a rear collision system. An extra $2600 will give you the 'Intellisafe' system which includes adaptive cruise control, semi-autonomous 'Pilot Assist' and lane keeping assist.
Mercedes-Benz GLS-Class10/10
At the time of this launch drive the GLS hadn’t been safety assessed by ANCAP, but you could make a small wager, like every penny you have to your name, that it will score a maximum five stars.
The expected active features are there, including ABS, ASR, and ESP, with additional tech including ‘Active Blind-Spot Assist’, ‘Active Brake Assist' (Merc-speak for AEB), active lane keeping and lane change assist, ‘Adaptive Brake’, ‘Attention Assist’, ‘Evasive Steering Assist’, ‘Parktronic’ (active parking assist with 360-degre camera), rear cross-traffic alert, traffic sign assist, and a tyre pressure warning system.
Then, if all that isn’t enough to avoid an impact the GLS is equipped with nine airbags (front and pelvis side for driver and front passenger, side for outer rear seat occupants, full-length curtain, and a driver’s knee bag), an active bonnet to minimise pedestrian injuries, and the ‘Pre-Safe Plus’ (flashes rear hazards to warn drivers closing too quickly from behind, tightening the belts at the same time, and locking the brakes if the GLS is stationary with a rear impact imminent).
Ownership
Volvo XC90
Warranty is three year/unlimited kilometres with free roadside assist for that period.
A 'SmartCare' service program gives you fixed-price servicing for up to five years/75,000km for $4075.
Mercedes-Benz GLS-Class7/10
The Mercedes-Benz range is covered by a three year/unlimited km warranty, which, like Audi and BMW continues to lag behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.
On the upside, Mercedes-Benz ‘Road Care’ roadside assistance is included in the deal for three years.
Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an 'Up-front' or 'Pay-as-you-go' basis.
As a guide, service pricing for the outgoing GLS is set at $2600 per service (up-front) and $3250 (PAYG), a saving of $650 a pop. Fourth and fifth services are also available for pre-purchase ($3550 and $4900).
