Summary

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.

Land Rover Discovery

I know what you’re thinking; this new Land Rover Discovery has gone a bit soft.

It’s built on the road-focused Range Rover Sport platform now. It’s lighter. And safer. Better equipped. Less, well, square. Hell, it’s even offered with a choice of two tiny four-cylinder engines, along with the traditional V6 unit.

And all of that surely means it’s just a little less rugged than the cars that have gone before it, right?

But Land Rover assures us that is actually not the case, declaring this all-new, fifth-generation car the most capable Disco ever.

So have they gone stark Rovering mad?

Verdict

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.


Land Rover Discovery7.6/10

It's a hell of a job, keeping the purists happy. But on first impressions, this new Disco should just about pull it off. Comfortable on the road, and capable of tackling anything its owners are likely to throw at it off it. Be prepared to spend up if you want a well-optioned one, though.

For us, though, the equipment of the HSE trim level blended with the power of the V6 engine is the pick of the bunch.

Design

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.


Land Rover Discovery8/10

Land Rover has attempted a sleeker, more urban design this time around, only without losing all of its boxy heritage, and the results are, well, a little confusing.

Viewed front on, this new Disco looks smooth and powerful, with a narrow bonnet that drops into the flared arches of the front wheels adding instant road presence. And from the rear it looks good, too.

Some will argue that the offset numberplate is an over-indulgence, or that it looks a little fridge-like with its narrow and tall dimensions, but we like it.

But it’s the three-quarter view that’s a little hard to stomach, with the smooth lines of the front end meeting the squared-off rear with all the subtlety of a wave meeting the shoreline.

Inside, though, it’s a picture of premium, with soft-touch cabin materials and a stylish, unfussy dash setup oozing a sense of considered quality.

Practicality

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.”


Land Rover Discovery9/10

Perhaps unsurprisingly, given it’s the size of small apartment block, the Disco’s people-and-cargo-carrying abilities are first rate. The official dimensions are 4970mm are long, 1846mm high and 2220mm wide, but that translates most simply as bloody massive.

Up front, there’s plenty of space for front-seat riders, though the super-wide central unit that runs from the dash to the centre console and houses everything from the touchscreen unit to the 4WD controls does eat into knee room a little. Front seat riders will share two central cupholders, and there’s room in the all doors for bottles.

Climb into the massive second row (it’s three-adults-across-the-middle big) and you’ll find your surroundings hinge on what trim level you’re in, with top-spec models adding climate control functions, dual USB points and two cupholders housed in a pulldown divider.

Opt for a seven-seat model (and you probably should) and you’ll find access to the third row a little tricky, but once there the space is genuinely impressive. At 176cm, I’m far from the tallest tester, but I do consider myself adult-sized, and I had clear air between my knees and the seat in front, and between my head and the ceiling.

Flatten the second and third seat (which you can do remotely via an app, should you so wish) and you’ll be able to squeeze 2,500 litres of cargo on board, helped by its two-metre load length and 1.4-metre load width. But drop only the third row and you’ll still get 1,231 litres. And you can add to that up to 21 separate storage areas that can add another 45 litres of space.

There’s also two or four ISOFIX attachment points, with two in the second row in all models joining another two in the third row for seven-seat cars.

Price and features

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.

 


Land Rover Discovery7/10

It’s a complicated lineup, with three engines available in any of the four trim grades, which in turn are offered with five or seven seats, plus there’s a launch special called the First Edition to further muddy the waters.

And that means you can technically climb into a pared-back Discovery S for a low $65,960 for a five-seater, or stretch to $131,870 for a full-fruit launch edition, with the vast area between those two numbers populated by everything else. 

The entry-level S ($65,960 - $84,671) is a fairly simple offering, with 19-inch alloys, cloth seats, a leather-wrapped wheel with paddle-shifters and two-zone manual climate control the pick of a sparse standard inclusions list. Cruise control is also standard fit, as is a raised inner-boot guard that stops your luggage falling out when you open the boot.

Step up to the SE ($77,050 - $94,701) and you’ll add standard air suspension, with fixed height settings for off-road, normal and access (which lowers the car if you need to pass under a low roof, for example), along with rain-sensing wipers and powered and heated wing mirrors.

LED headlights (with an undeniably cool Nike Swoosh-style design) and leather seats also join the party at the SE level, as does ambient interior lighting and front parking sensors, while your eight-inch touchscreen is now nav-equipped, and pairs with a better, 10-speaker stereo.

Next is the HSE trim ($87,150 - $103,661), which adds some cool design elements, like LED taillights, 20-inch alloys outside, along with winged headrests, quality woodgrain highlights and even more ambient lighting inside. Your climate is now three-zone, too, and some bonus hiding holes appear (like a clever storage compartment under the front cupholders that only appears when you slide the unit forward). Your stereo is upgraded to a 10-speaker Meridian unit, too, and is controlled through a bigger, 10-inch touchscreen.

At the top of the regular Disco family tree, is the HSE Luxury ($100,950 - $117,461), which is a not-insignificant amount of money no matter which way you shake it. For that spend, though, you’ll add a powered sunroof, unique 20-inch alloys and finer leather on your seats, which are now also heated and cooled in the front. You’ll also add a surround-view camera and get the pick of the sound-systems; a 14-speaker Meridian unit. 

On the 4WD front, everything but the entry-point S models get a low-range-equipped 4WD system (the S is high-range only), and Range Rover's Terrain Response (which allows you to select traction settings based on the whether you're driving one mud, rocks, sand etc) is standard across the range. The newer Terrain Response 2, which automatically senses the surface and adjusts accordingly, is a cost option.

Engine & trans

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.


Land Rover Discovery8/10

There’s three diesel power plants on offer, and each pairs with an eight-speed automatic gearbox that channels power to all four wheels. 

The entry level (and destined to be unpopular) option is the lesser of the two four-cylinder engines, 2.0-litre “Ingenium” unit that will deliver 132kW and 430Nm.

We’re yet to test the low-output option, to be honest, but we’d be shocked if buyers found it ample to shift the Disco’s bulk, even if this new model is a staggering 480kg lighter than its predecessor. Land Rover says that engine will help produce a 10.5-second sprint to 100km/h.

Better, then, to step up to the more powerful version of that engine, which produces 177kW and 500Nm thanks to some tuning tweaks. As a result, a far more palatable sprint time of 8.3 seconds can be achieved. 

But for ours, the best-suited option remains the powerful 3.0-litre diesel V6, which will fire 190kW and 600Nm to the tyres on demand. And the result of all this extra grunt? A slightly improved sprint claim of 8.1 seconds. But those numbers don’t tell the full story of an engine that feels more urgent and eager when you prod the accelerator.

Fuel consumption

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.

 


Land Rover Discovery8/10

The lowest-output diesel will drink 6.3-litres per hundred kilometres on the claimed/combined cycle, with that number climbing to an only slightly worse 6.5 litres for the more powerful four-cylinder unit. 

Opt for the V6, though, and your fuel use climbs to 7.2 litres per hundred kilometres (claimed/combined). 

Driving

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.


Land Rover Discovery7/10

Land Rover is faced with the most impossible of challenges with this new Disco. For one, it’s filling in for the legendary Defender as the brand’s most capable offering, and that means it needs to be able to go places and do things a Range Rover simply can’t. Anything less will have the purists frothing.

But equally, Land Rover knows that the overwhelming majority of its customers are unlikely to tackle anything more challenging than a suburban speed bump, and so they needed to soften its image and improve its road manners, without sacrificing capability.

So Land Rover pointed the Disco’s nose towards Australia’s red centre, putting its fleet through their paces on the sealed roads and red dirt tracks that encircle Uluru. And on a custom-built track consisting of moguls, water crossings and angled climbs sharp enough to put some articulation pressure on the wheels, the Disco conquered all before it with ease. 

It must be said, though, that there was nothing on offer that would genuinely challenge it, but equally, the Disco always felt like it had plenty in reserve, too. And with a maximum 283mm ground clearance, 500mm of wheel articulation and a wading depth of 900mm (which is 200mm more than outgoing model), along with air suspension on all but the entry-level S, it does point to some genuine off-road potential.

On our brief tarmac drive we were surprised by the smooth and steady power delivery of the bigger four-cylinder diesel, which propels the two-tonne-plus Land Rover along with surprising ease. It’s not fast, but it never feels underwhelming.

But the pick for us was the six-cylinder option, which unlocks its 600Nm low in the rev range and feels a far more natural fit for the big Disco. It’s louder and little more gruff than its four-cylinder sibling, but it feels faster, too. And for us, that’s a fair trade off.

The Disco happily switched from tarmac to rutted tracks with ease, and while the super-smooth tarmac of the Northern Territory wasn't much of a challenge, it sorted out the worst of the off-road stuff with little bother.

Australia’s outback famously offers up very little in the way of cornering, but the few we did encounter had us a little concerned with the top-heavy nature of the Discovery, with sharp direction changes sending passengers into a noticeable wobble. 

Still, our limited wheel time means we’ll be reserving final judgement until we can spend more time with each variant, but our taste-test sample reveals a car that does appear to straddle that line between capable and comfortable.

Safety

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).


Land Rover Discovery7/10

The Discovery range has been awarded the maximum five-star ANCAP safety rating, six airbags (front, front-side and curtain), a reversing camera, AEB and Lane Departure Warning fitted on every model, joining  the usual suite of traction and braking aids.

Ownership

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).


Land Rover Discovery7/10

The Discovery range is covered by a three-year, 100,000km warranty, but you can extend that to five years at an extra cost. You can also pre-pay your service costs for the first five years of ownership.

The four-cylinder engines get genuinely impressive service intervals of 24 months/34,000km, while the V6 requires a trip to the dealership every 12 months or 26,000km.
