What's the difference?
It’s fair to say Mercedes-AMG GLS63 buyers really want it all; good looks, cutting-edge technology, seven-seat practicality, leading safety and V8 performance to name a few key desirables. And, lucky for them, the new model is finally here.
Yep, the latest GLS63 is yet another exercise in excess, leaving very little to be desired by its buyers. Indeed, it ticks almost every box when it comes to a utility vehicle that well and truly puts the sports in Sports Utility Vehicle.
But, of course, this raises questions over whether or not the GLS63 is trying to do too much. And given this model does a whole lot more than its predecessor, these questions need to be answered again. Read on.
If you’re looking for a heavy duty 4x4 wagon that can tackle the toughest off-road terrain and haul heavy loads with equal competence, there’s a handful of models derived from 4x4 one-tonne utes that can deliver.
Sharing the same rugged truck-style construction, with a wagon body mounted on a separate ladder-frame chassis, the local contenders in this four-way fight comprises Ford’s Ranger-derived Everest, Isuzu’s D-Max-based MU-X, Toyota’s HiLux-sharing Fortuner and Toyota’s 70 Series LandCruiser wagon (aka 76 Series) which comfortably predates its rivals having been launched in 2007.
Although the 76 Series five-seater does not offer a third row of seats like its rivals, it maintains a strong following with loyalists.
And its desirability has no doubt grown with the release of an updated range in late 2023, which for the first time offered buyers the choice of the venerable V8 turbo-diesel manual or new four-cylinder turbo-diesel automatic.
Given Toyota has been working around the clock to fill thousands of 70 Series orders for the traditional V8 manual, we thought it timely to revisit this much-loved drivetrain in wagon form to find out why it enjoys enduring popularity for both work and recreational roles.
The GLS63 is an intimidating beast from afar, but it rewards its occupants in almost every way. Yep, there really isn’t a box it doesn’t tick without serious compromise, such is its breadth of capability.
If there was ever a Swiss Army Knife of cars, the GLS63 is definitely a contender for the title, one that makes it very hard to wipe the smile off your face. Just make sure you can fit it in your garage first…
Life is full of compromises and the 76 Series wagon is no exception. The payback for accepting its minimal cabin storage, comfort-challenged rear seat, no ANCAP, high purchase price, high servicing costs etc is that you get a genuinely heavy duty 4x4 wagon with huge GVM/GCM ratings unmatched by its ute-derived rivals.
The V8 manual or four-cylinder auto have different characteristics but similar competence, with the manual obviously requiring more physical effort, so it comes down to personal preference. And we’re sure, given its long history, there’s plenty of emotional attachment driving the bulging V8 order book. Either way, with its enormous fuel tank and revered off-road prowess, this rugged and dependable wagon has a proven ability to take you and your crew deep into the wilderness – and get you home again.
If the GLS63 was a Marvel superhero, it would undoubtedly be the Hulk. Simply put, it has road presence like few others. In fact, it’s frankly menacing.
Of course, the GLS is already pretty intimidating due to its sheer size and blocky design, but the GLS63’s full-fat AMG treatment takes it to another level.
Naturally, the GLS63 gets an aggressive body kit, with its purposeful bumpers, side skirts and rear spoiler serving as instant reminders of what you’re dealing with, but it’s AMG’s signature Panamericana grille insert that really hammers home the point.
Around the side, the GLS63’s 22-inch alloy wheels with staggered tyres (front: 275/50, rear: 315/45) make their presence known, positioned below the wheelarch extensions.
That said, some fun’s also had at the rear end, where the GLS63’s diffuser element integrates the foreboding sports exhaust system with quad tailpipes very neatly.
The focused Multibeam LED headlights also look the part, while the opposing LED tail-lights tie everything together outside quite nicely.
Inside, the GLS63 stands out from the GLS crowd with its sports steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are covered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.
Of note, the doors bins are unfortunately of the hard plastic variety, which is very disappointing in a vehicle that costs this much. You would expect that cow hide would also been applied to them, but alas it isn’t.
The GLS63’s black headliner serves as an obligatory reminder of its sporting intent, and while it makes for a dark cabin, metallic accents are prominent throughout, while the optional trim (our test vehicle had carbon-fibre) mixes things up, alongside the ambient lighting.
And let’s not forget the GLS63 is still loaded with plenty of cutting-edge technology, including a pair of 12.3-inch displays, with one the central touchscreen and the other the digital instrument cluster.
Both are powered by Mercedes’ class-leading MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up arguably remains the best there is today thanks to its speed and breadth of functionality and input methods.
The 76 Series wagon has the shortest wheelbase of the four-model 70 Series range at 2730mm, which makes it the most responsive to steering input.
It also has the shortest overall length (4910mm) and in GXL form the tightest turning circle (13.2 metres) which can make life easier in tight situations, from busy car parks to challenging bush tracks.
Off-road credentials include 33 degrees approach and 23 degrees departure angles, plus 290mm of ground clearance. Curiously, Toyota does not publish a ramp break-over angle.
The interior is B for basic, in true 70 Series tradition, with seat fabrics and colours reminiscent of circa-1990s Toyotas.
The most noticeable differences between the four-cylinder auto and V8 manual cabins are that the V8 version has an extra pedal and misses out on the auto’s full-length centre console, which offers additional and much-needed storage space.
There’s ample headroom but that generosity does not extend to rear seat comfort, at least for tall people like me (186cm).
The entry pathway between the B-pillar and rear seat base cushion is narrow and, when sitting behind the driver’s seat in my position, my knees are pressing into the front seat’s backrest.
So, it’s not possible for two big blokes to sit one behind the other without the ‘one’ behind feeling squished.
Fortunately, the 60/40-split rear seat allows adjustment of backrest angles and for those seated in the centre there’s a nice flat floor with no transmission tunnel to straddle. However, the centre passenger’s back/backside are directly over the 60/40 split, which is quite a wide gap (about 15mm) that's intolerable for anything longer than short trips.
Rear shoulder room for three adults is also squeezy, so keep these rear seat issues in mind if planning an adventure for five.
Measuring 5243mm, 2030mm wide and 1782mm tall with a 3135mm wheelbase, the GLS63 is an upper-large SUV in every sense of the term, which means it’s also very practical.
For example, cargo capacity below the load cover is decent, at 355L, but stow the 50/50 power-split-folding third row via the boot and it’s very good, at 890L, or drop the 40/20/40 power-split-folding middle bench, too, and it becomes a cavernous 2400L.
Better yet, the boot’s aperture is almost square, and its floor’s flat, while there’s no load lip to contend with, making loading bulkier items even easier. Up to four tie-down points are also on hand (depending on seating configuration) to secure loose cargo.
Under the false floor is the space-saver spare, which is to be expected, but what isn’t expected necessarily is the fact there’s also enough room there for the cargo cover when it’s not in use, which would be the case if six or more passengers are regularly onboard.
Moving into the power-sliding second row, the GLS63’s practicality is once again brought to the fore, with up to six-plus inches of legroom available behind my 184cm driving position.
There’s also two inches of headroom with the panoramic sunroof in situ, not to mention just enough toe-room. The GLS63’s small transmission tunnel and sheer width also mean three adults can be seated on the middle bench with few complaints.
Amenities-wise, the second row has map pockets on the front-seat backrest and a small fold-down cubby below the rear climate controls, with it containing two slots for smartphones and a pair of strategically placed USB-C ports.
The rear door bins can take one large bottle each, while a fold-down central armrest is also on hand, featuring a shallow tray and retractable (and flimsy) cupholders.
Alternatively, the $2800 Rear Seat Comfort Package fitted to our test vehicle subs in a tablet that can control the multimedia system, a wireless smartphone charger and a small cubby into the former, as well as a heated/cooled cupholder atop the rear of the centre console.
In the third row, it’s not quite as roomy if you’re an adult. With the middle bench in its most accommodating position, my knees still brush up against its backrest, which is to be expected given it’s primarily designed for children. I also have an inch of headroom there.
Nonetheless, getting in and out of the third row is relatively easy as the power-operated middle bench tumbles forward and provides just enough space to make entry and exit somewhat graceful.
When seated, rear occupants are treated to two USB-C ports and one small cupholder each, so they’re arguably taken better care of than those in the middle.
Child seats are well and truly accommodated, with four ISOFIX and five top-tether anchorage points fitted across the second and third rows, although the latter will inevitably prove to be a much tighter fit.
The driver and front passenger are still taken care of, with a front cubby taken up by two heated/cooled cupholders, a wireless smartphone charger, two USB-C ports and a 12V power outlet, while their door bins take one large and one small bottle each.
In-cabin storage options include the large central storage bin, which hides another USB-C port, while the glovebox is on the smaller side, with about a third of it taken up by the fragrance, which is pumped into the cabin to ensure the interior always smells its best.
Our GXL V8 test vehicle’s 2355kg kerb weight and 3510kg GVM results in a Herculean payload rating of 1155kg.
It’s also rated to tow up to 3500kg of braked trailer and with its towering 7010kg GCM (or how much it can carry and tow at the same time), that means it can tow its maximum trailer weight while carrying its maximum payload, which is impressive.
These substantial load ratings make the 76 Series a popular choice for hardcore adventurers that need to carry a crew and everything else (including the kitchen sink) when venturing far off the beaten track for extended periods.
The absence of a third row of seating creates a spacious rear load area, accessed through asymmetric barn-doors, the larger of which carries the spare wheel/tyre.
The rear seat backrests can fold flat to provide more load volume and their base cushions can tumble forward to create even more space. The GXL’s load floor is carpeted and equipped with four anchorage hooks for securing load straps or cargo nets.
Cabin storage for personal items is in short supply, as the driver and front passenger only get a narrow and shallow bin (more like a document holder) at the base of each door, with a small bottle/cupholder in the passenger side bin.
There’s also a glove box, single small-bottle/cupholder next to the gearstick and a tiny console box between the seats.
Rear passengers only get mesh pockets on the front seat backrests, as there are no bins or bottle/cupholders in the rear doors.
There’s also no fold-down centre armrest, so no bottle/cupholders to be found anywhere. We reckon aftermarket cabin organisers would be popular purchases by 76 Series owners!
Priced from $255,700 plus on-road costs, the GLS63 commands a $34,329 premium over its predecessor, although buyers are arguably getting more bang for their buck than before, even if it does sit well clear of the two other GLS variants: the $147,100 GLS450 and $153,900 GLS400d.
Standard equipment not already mentioned in the GLS63 includes regular metallic paintwork (our test vehicle was finished in Selenite Grey), dusk-sensing lights, rain-sensing wipers, power-folding side mirrors with heating, soft-close doors, roof rails, rear privacy glass and a power-operated tailgate.
Inside, keyless entry and start, augmented reality (AR) satellite navigation with live traffic, digital radio, a 590W Burmester surround-sound system with 13 speakers, a head-up display, a panoramic sunroof, heated seats (including middle outboard) and armrests, cooled front seats with massaging functionality, power-adjustable seats, a power-adjustable steering column, temperature-controlled front cupholders, five-zone climate control, stainless-steel pedals and an auto-dimming rearview mirror feature.
With BMW not offering an X7 M (although the slightly smaller $209,900 X5 M Competition is available) and the $208,500 Audi RS Q8 really from the segment below, the GLS63 does not have a direct rival in the Upper-large SUV segment.
In fact, the $334,700 Bentley Bentayga V8 is actually the model that comes closest to the GLS63 when looking for a seven-seater with a similar level of bent-eight performance.
The 76 Series wagon is available in work-focused Workmate grade, or premium GXL, as per our example. Equipped with the 4.5-litre turbo-diesel V8 and five-speed manual transmission, it has a list price of $83,900.
The GXL costs $8300 more than the Workmate V8 equivalent and for that extra spend you get an expanded menu of standard equipment including front and rear diff-locks, 16-inch alloy wheels and 265/70R16 tyres (with a full-size spare), wide front mudguards, wheel arch flares, LED front fog lights, aluminium side-steps and chrome bumpers.
Interior enhancements include keyless entry and central-locking, fabric seat and door trim, carpet flooring, power windows, front seat back-pockets, four-speaker audio and two USB-C ports (we’re surprised Toyota did not provide the usual choice of USB-A and USB-C ports).
These GXL features are in addition to standard equipment added as part of the recent 70 Series upgrade, including a redesigned front fascia with LED lighting including DRLs and auto high beam, 60/40-split rear seat (wagon only), multi-function steering wheel controls, a 4.2-inch driver’s multi-info display and upgraded multimedia with a 6.7-inch touchscreen display, digital radio and wired Apple and Android connectivity. Safety has also been upgraded with lane-keeping and speed sign recognition.
The GLS63 is powered by a familiar 4.0-litre twin-turbo V8 petrol engine, with its version producing a thumping 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.
This unit is mated to a nine-speed torque-converter automatic transmission and AMG’s fully variable 4Matic+ all-wheel-drive system with torque vectoring and a rear limited-slip differential.
This set-up also features Mercedes’ EQ Boost 48V mild-hybrid system, which actually gives a 16kW/250Nm electric boost in short bursts, such as when accelerating off the line.
Speaking of which, the GLS63 sprints from a standstill to 100km/h in just 4.2 seconds, while its top speed is electronically limited to 250km/h.
Toyota’s (1VD-FTV) 4.5-litre turbo-diesel V8 produces 151kW at 3400rpm. More importantly, its 430Nm of torque is served at full strength across a vast 2000rpm-wide torque band between 1200-3200rpm. This showcases its remarkable flexibility for heavy load-carrying, towing and off-road slogging.
This engine is paired with the equally popular (H152F) five-speed manual transmission, which features an ultra-short first gear ideal for low-speed off-road driving or getting heavy loads moving. By comparison, the overdriven top gear provides long enough legs for economical cruising at highway speeds.
Its part-time, dual-range 4x4 transmission offers a 44:1 crawl ratio, combined with Toyota’s outstanding active traction control, automatic-locking front hubs and (standard on GXL) front and rear diff locks. This is a formidable off-roader.
The GLS63’s fuel consumption on the combined-cycle test (ADR 81/02) is 13.0L per 100km, while its carbon dioxide emissions are 296 grams per km. All things considered, both claims are unsurprisingly high.
In our real-world testing, we averaged a fearsome 18.5L/100km over 65km of driving, split between highways and country roads, so not your usual mix. A very heavy right foot definitely influenced that result, but don’t expect to do too much better in a normal run.
For reference, the GLS63’s 90L fuel tank can be filled up with 98RON petrol at a minimum.
Toyota’s official average combined cycle consumption figure for the V8 manual is 10.7L/100km. The dash display was claiming 10.9 when we stopped to refuel at the completion of our 276km test, which comprised a mix of city, suburban, highway and dirt driving with a variety of occupant loads.
Interestingly, the dash readout was identical to our own 10.9 figure calculated from fuel bowser and tripmeter readings, which confirms the accuracy of the LandCruiser’s fuel calculations and the efficiency of its relatively large V8 in a vehicle weighing more than two tonnes in mostly urban driving.
So, based on our figures, it has a vast 'real world' driving range of more than 1100km from its huge 130-litre tank.
Frankly, the GLS63 has absolutely no right being as capable as it is. It’s a really big bus that’s legitimately convinced it’s a sports car half its size.
Being a GLS variant, the GLS63 has independent suspension consisting of four-link front and multi-link rear axles with air springs and adaptive dampers, but its party trick is the addition of active anti-roll bars.
In what feels like magic, the GLS63 is simply not intimidated by corners, despite having massive dimensions and a considerable 2555kg (kerb weight) to deal with.
The active anti-roll bars make the GLS63 so much easier to drive fast through the twisty stuff, almost eliminating body roll, taking one key variable out of the equation for the driver. Active engine mounts are also fitted, helping to settle things even further.
The electric power steering on hand is also good. It is speed-sensitive and has a variable ratio, which basically makes the set-up more direct when it needs to be. It’s typically light in hand, too, until one of the sportier drive modes is engaged and extra heft is added.
So, handling is scarcely believable, which means the ride must be compromised, right? Yes and no. With the adaptive dampers in their softest setting, the GLS63 is very compliant. In fact, we’d say it feels luxurious when compared to other high-performance SUVs.
That said, our test vehicle was fitted with the optional 23-inch alloy wheels ($3900), which look the part but expose sharp edges and other road imperfections, not to mention generate noise easily heard inside. Naturally, feedback is exacerbated in the sportier drive modes.
Anyway, there’s more performance, and the GLS63 has the rest in spades. Its engine is a powerhouse in every sense of the word. It’s so powerful, in fact, that it hilariously hunkers down off the line or when suddenly accelerating at low speed.
Thanks to the mild-hybrid system, wads of torque is available from the get-go, making for a highly responsive driving experience, even in those rare moments when the engine isn’t on song.
While not as characterful as some of the other members in the 63 series, the GLS63 still makes some thoroughly entertaining noises, with its sports exhaust system popping like mad while on the overrun.
All of this ability is very well and good, but you need to be able to pull up quickly, and the high-performance braking package (400mm front and 370mm rear discs with six-piston fixed callipers and single-pot floating stoppers respectively) mercifully does exactly that.
The aluminium side-steps, along with handles on the A- (and B-) pillars, assist climbing aboard and all-around vision is good thanks to large glass areas, sizeable door mirrors and a reversing camera, although the rear seat headrests partly block vision through the central rear-view mirror.
It’s the best off-road driving position an adventurer could ask for, combining good comfort with a commanding view over the bonnet and out each side, which allows accurate vehicle placement in all terrain.
The ride quality is firm, as you’d expect in a vehicle that can legally haul more than seven tonnes, but supple enough to absorb bumps without jarring. This is aided by the relatively baggy sidewalls of the GXL’s tyres.
Old school recirculating-ball steering is low-geared and lightly weighted with ample free play off-centre to soften off-road blows, which is highly valued by loyal customers.
The wagon’s shorter wheelbase, tighter turning circle and shortest overall length than its 70 Series stablemates provides enhanced steering response and manoeuvrability, combined with four-wheel disc brakes giving ample stopping power.
Given the V8’s torque band is as wide and flat as Lake Eyre, it will accelerate smoothly in top gear from under 1000rpm, so there’s no need to shift your way through all five cogs from each standing start. In fact, for road use without a load, we always drive it like a three-speeder, using only first, third and fifth gears.
Noise levels are reasonably low in city and suburban driving. However, they do become more intrusive at highway speeds, when engine, tyre and wind noise combine to require raised voices, even though the overdriven top gear ensures a relatively low 2200rpm at 110km/h.
We also detected some squeaks and rattles emanating from the rear of the vehicle on bumpy roads, which suggested it was coming from the spare tyre mounted on the back door.
Neither ANCAP nor its European counterpart, Euro NCAP, have awarded the GLS range a safety rating, but it’s fair to assume it would perform well in testing.
Advanced driver-assist systems in the GLS63 extend to autonomous emergency braking with pedestrian and cyclist detection, lane-keep and steering assist (including emergency), adaptive cruise control, active blind-spot monitoring, rear cross-traffic alert, traffic sign recognition, driver attention alert, high-beam assist, tyre pressure monitoring, hill-descent control, hill-start assist, park assist, surround-view cameras and front and rear parking sensors.
Other standard safety equipment includes nine airbags (dual front, front-side, curtain and rear-side plus driver’s knee), anti-skid brakes (ABS), electronic brake-force distribution (EBD) and the usual electronic stability and traction control systems. Yep, it doesn’t leave much to be desired on the safety front.
No ANCAP rating for the wagon, as the single cab-chassis version is still the only 70 Series variant to have achieved five-stars and that was back in 2016.
And although the wagon has AEB with day/night pedestrian and daytime cyclist detection plus driver and front passenger front airbags, it misses out on side-curtain and driver’s knee airbags.
New safety features include lane-departure alert with steering assist, speed sign recognition and auto high-beam control. There are no ISOFIX child seat anchorages in the rear seat, but there are three top-tethers above the rear barn-doors.
As with all Mercedes-AMG models, the GLS63 comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.
The GLS63’s service intervals are relatively long, at every 12 months or 20,000km (whichever comes first). Better yet, it’s available with a five-year/100,000km capped-price servicing plan, but it costs $4450.
The LandCruiser is covered by Toyota's five-year/unlimited km warranty.
Scheduled servicing is every six months/10,000km whichever occurs first.
Capped-price servicing of $525 applies for each of the first 10 scheduled services, which is a pricey $1050 per year or $5250 over five years.
