Mercedes-Benz GLS-Class vs Toyota Prado

What's the difference?

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…

The Kakadu treatment adds a welcome prestige to the Prado which is already a functional, comfortable daily driver and a very capable 4WD tourer as is.

It's reliably effective off-road and though it lacks the over-the-top macho appeal of something like the 70 Series LandCruiser, it still makes a very appealing platform as a touring vehicle. But this flat-tailgate Kakadu, minus the extra fuel capacity of a Prado with the tailgate-mounted spare, loses tourer appeal due to that fact.

If you choose to opt for a lower-spec Prado you'll forgo some nice Kakadu features – such as KDSS – but it'll still be a Prado after all. Money saved can be spent on aftermarket gear to fit out your new adventure machine.

Or you can wait in line with everyone else for the 2024 Prado...

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 flat tailgate Kakadu is 4825mm long (4995mm with tyre mounted on the tailgate), 1885mm wide, 1880mm high, and it has a kerb weight of 2290kg (2350kg for the standard Prado).

The 2024 Prado – or the 250 Series as it's known in other markets – has an identical wheelbase to the 300 Series (2850mm), so it's 60mm longer than the current model's. 

That next-generation Prado will reportedly measure 4925mm long, 1980mm wide and 1870mm high, so it's 100mm longer, 95mm wider and 20mm taller than the current Prado.

As mentioned, our test Prado's flat tailgate pack cuts fuel capacity from 150 litres to 87 litres, which results in a substantial drop in driving range. So, it'll factor heavily in the buying decision, especially if the potential owner is keen on off-road touring.

The current Prado's design is less blocky than previous iterations but retains a recognisable Prado chunkiness. If you like your SUVs even more streamlined, but with a healthy dose of retro, you'll have to wait for the 2024 Prado.

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.

The Prado's interior has a comforting familiarity about it. Sure, it feels a bit dated, but I like it. It's plush, functional and very comfortable.

The front seats are heated, ventilated and power-adjustable and the driver and front passenger have easy access to the 9.0-inch touchscreen multimedia system, which is simple enough to operate.

There's also the usual complement of cupholders (two in front of the centre console) and USB charge points, as well as the refrigerated cool box that replaces the centre console.

The Kakadu has three-zone climate control so everyone has a hand in how toasty or chilled they are during road trips.

Floor mats in the Kakadu are carpet, not the all-weather rubber mats you get in lower-spec Prados.

The second-row is a 40/20/40 sliding split and the outer seats are heated. Second-row passengers get directional air vents, fan and temp controls, seat-heating controls, 12V point (all in the rear of the centre console), and a fold-down centre armrest with built-in dual cupholder.

The second-row seats have three top-tether points and two ISOFIX locations.

There are mesh map pockets on the driver and front passenger seat-backs.

The third-row seats – in a 50/50 split fold-flat configuration – are button-operated and power-folding. Passengers have a cupholder each, as well as air vents and a speaker mounted nearby. They also have a clear view of the 9.0-inch ceiling-mounted DVD screen.

With the third-row seats in use, boot space is listed as 104 litres.

If not in use, the rear-most seats can be power-folded away at the press of a button and the area used for luggage, concealed by a retractable cargo blind. With the third row stowed away, there's a claimed 553 litres of cargo space.

With the second and third rows folded down and out of the way, there's a claimed 974 litres available.

For reference, the 2024 Prado will have a 12.3-inch multimedia system (including wireless Apple CarPlay), as well as seating for five or seven passengers.

Our test vehicle is the Prado Kakadu, a seven-seat 4WD wagon with a list price of $87,468, excluding on-road costs.

Standard features include a 9.0-inch touchscreen multimedia unit (with Apple CarPlay, Android Auto and sat-nav), three-zone climate control air conditioning, a JBL 14-speaker sound system, a rear-seat entertainment system (Blu-ray DVD player) with 9.0-inch screen and three wireless headsets, button-operated third-row power-folding seats, panoramic-view monitor, tilt-and-slide moonroof, and 19-inch alloy wheels.

It also has a premium woodgrain-look power-adjustable steering wheel with paddle shifters, leather-accented, heated and ventilated front seats, dual-range 4WD, as well as 4WDing-suitable driver-assist systems, such as crawl control and multi-terrain select (both for off-roading), adaptive variable suspension (with three modes: comfort, normal and sport), rear air suspension and Toyota's 'Kinetic Dynamic Suspension System' (KDSS).

Driver-assist tech includes 'Toyota Safety Sense' (including 'Pre-Collision Safety System' with pedestrian detection, 'High Speed Active Cruise Control' and more).

A flat tailgate option (which moves the full-size spare wheel from the rear door to the Prado's underbody) is available for the Kakadu. Our test vehicle has it.

Worth noting that choosing this option reduces your fuel capacity from 150 litres to 87 litres, because you sacrifice the 63-litre sub-tank so the spare tyre can be fitted underneath the vehicle.

Kakadu interior seat trim choices are beige leather accented or black leather accented.

Exterior paint choices include 'Graphite', 'Espresso Brown', 'Glacier White', 'Crystal Pearl', 'Silver Pearl', 'Peacock Black', 'Eclipse Black', 'Ebony', 'Wildfire' and 'Dusty Bronze' (premium paint, on our test vehicle). Premium paint costs $675 extra.

There are accessories aplenty available for the Prado, but there are also bundled packs which incorporate several accessories to suit your lifestyle.

The 'Adventure Pack' includes an alloy bull bar (commercial), light bar (fitting kit sold separately), snorkel, roof rack with alloy roof tray (both sold separately) and weather-shields (left and right sold separately).

Then the 'Weekend Getaways' pack includes a nudge bar (black), light bar (fitting kit sold separately), bonnet protector (tinted), roof racks with bike carrier (both sold separately), tow bar, tow ball and trailer wiring harness.

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.
 

The Kakadu has a 2.8-litre four-cylinder turbo-diesel engine – producing 150kW at 3000-3400rpm and 500Nm at 1600-2800rpm – and that's matched with a six-speed automatic transmission.

This is a solid not dynamic combination, which is fine with me because it yields a drive experience that's equal parts relaxed, assured and undemanding.

Our test Prado has a full-time four-wheel drive system with high- and low-range.

Note: the Prado has a diesel particulate filter (DPF) and issues linked to those systems have been well documented, so head to our Toyota Prado problems page to stay up to date with any DPF details.

The next-generation Prado will feature five powertrains globally, however, Australia will only get a 48-volt mild-hybrid version of the current model's 2.8-litre four-cylinder turbo-diesel engine (150kW and 500Nm), with identical power and torque outputs as the existing engine.

The new hybrid engine will be matched to a new eight-speed torque-converter automatic transmission.

It will have full-time all-wheel drive, a low-range transfer case, a centre diff lock, a electronic locking rear diff and a button-operated swaybar disconnect system – not Toyota's KDSS – aimed at yielding improved wheel travel while off-roading.

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.

The Prado has an offical fuel consumption figure of 7.9L/100km (on a combined cycle).

I recorded 13.4L/100km on this test. I did a lot of high- and low-range 4WDing – but the Prado never seemed to have to work hard.

It has 87L fuel tank capacity – that's 63 litres less than any Prado that does not have the flat tailgate, and going by our on-test fuel-consumption figure you could reasonably expect a full-tank driving range of about 650km.

The Prado with the rear-mounted spare has a 150-litre tank so, based on my fuel figures, you could reasonably expect about 1120km from a full 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 Kakadu is an easy-driving and very comfortable 4WD wagon.

It's quiet inside the Prado with most external noise kept to a muffled hum.

Steering has a nice weight to it, although it can feel a bit floaty if you're used to a more tightly controlled vehicle. The driver can dial-in their position as the steering wheel is electric tilt-and-telescopic adjustable.

The Kakadu has a 11.6m turning circle and feels nimble along crowded streets and in busy regional centres.

The 2.8 litre turbo-diesel engine and transmission pairing is an unhurried, almost sluggish combination, yielding a relaxed drive experience, but acceleration is gutsy enough to punch the Prado off the mark and get it moving at pace to overtake when needed.

Brakes – ventilated discs at each corner – were able to bring the 2.3 tonne Prado to a rapid controlled stop every time I stomped them into submission during my patented ‘Watch out for that kangaroo!' emergency-braking tests on dry and wet bitumen.

One of the Kakadu's major points of difference with lower-spec Prados is that it has Toyota's 'Kinetic Dynamic Suspension System' (KDSS), which helps iron out most ride and handling irregularities.

KDSS hydraulically alters tension on the sway bars to suit the terrain; on-road, it tightens them for reduced body roll and more dynamic handling, and off-road it loosens them for greater wheel travel to further improve performance.

The Kakadu also has adaptive variable suspension which can be set to one of three modes ('Comfort', 'Normal' or 'Sport') via an in-cabin switch to help dial-in smooth and well-sorted ride and handling; and its height-adjustable rear air suspension with switchable low, normal or high modes.

The Kakadu's Dunlop Grandtrek AT30 tyres (265/55 R19) are well-suited to on-road driving, but fall a bit short, performance-wise, when 4WDing.

On the loose-gravel dirt track that leads to my unofficial 4WD testing ground, the route had been gouged by deep ruts from recent rains. The Kakadu managed it all well.

And a lot of the credit of that controlled ride and handling is due to KDSS, loosening swaybars to suit the terrain, allowing axles full-stretch articulation as required.

And that's very handy at low speeds when sustaining safe and controlled momentum via maximised traction is the goal.

And this was even more evident when I tackled my favourite set-piece rocky hill-climbs.

The Kakadu trucked over the undulating ground at low revs and with wheels dipping and rising as they stuck to the dirt. Wheel travel in a standard Prado is fine but the KDSS-equipped Kakadu gets even more flex on the move.

It conquered everything with impressive ease, only ever scrambling momentarily for grip because of its tyres.

Swap those with a decent set of all-terrains and you'd instantly make a great off-roader even better.

Steering retains a nice balance at low speeds, throttle response is good (not touchy over bumpy terrain), the driver has plenty of visibility (crucial for low-range highly technical 4WDing that relies so heavily on choosing the correct line) and the Kakadu's dimensions offer off-road angles – of 30.4 degrees (approach), 21.2 (ramp-over) and 23.5 (departure) – that are good for a cityfied SUV wagon.

The Kakadu has plenty of torque across a wide rev range, and front, centre and rear locking differentials.

It also has a raft of driver-assist tech, including crawl control (low-speed low-range cruise control/traction control with five selectable speeds), and 'Multi-Terrain Select' (with off-road driving modes that adjust steering, throttle and traction control to suit the terrain you're on, e.g. rock and dirt, mud and sand etc).

Towing capacity is 750kg (unbraked) and 3000kg (braked).

The Kakadu has a gross vehicle mass (GVM) of 2990kg and a GCM (gross combined mass) of 5990kg.

For reference, towing capacity on the 2024 Prado is tipped to be 3500kg (braked), but, at time of writing, this was unconfirmed.

The Prado has the maximum five-star ANCAP safety rating from 2011, but that rating expired at the end of 2022 and Toyota has no plans to re-test this generation. As mentioned earlier, the new Prado is not expected here until 2024.

The second-row seats have three top-tether points and two ISOFIX locations.

The Prado has seven airbags, three top-tether points and two ISOFIX locations in the second row, and is stacked with driver-assist tech including pre-collision avoidance with AEB, high-speed active cruise control, lane-departure alert with steering assistance, automatic high beam, road sign assist and more.

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 Prado has a five-year/unlimited kilometre warranty, which is the mainstream market standard.

Maintenance is scheduled for every six months or 10,000km, which is more frequent than the more common 12 months/15,000km.

Every new Prado comes with capped price servicing of $260 per service up to the three-year mark, for a total of $1560 over three years.
