Toyota HiLux vs Mercedes-Benz GLS-Class

What's the difference?

The HiLux’s age-defying sales and resale values confirm it’s still one of the top two 4x4 dual cabs on the market. However, its new V-Active technology feels underdone, as it adds weight (we reckon about 40kg) and complexity without gains in performance you can feel or economy you can meaningfully measure. Hopefully, Toyota’s next crack at a 'hybrid' HiLux will be more convincing.

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 HiLux’s enduring appeal is the ‘unbreakable’ feel when you step aboard. Even though its curvaceous styling is increasingly dated, we can’t fault the build quality as it displays a peerless standard of fit and finish which never wavers.

Our only major gripe (since its launch in 2015) is the cramped rear seating. It’s particularly tight for tall people, giving that I’m 186cm and when sitting in the rear seat with the driver’s seat in my position, my knees are pressed into its backrest and my head rubs on the roof lining.

Shoulder room for three large adults is equally challenging and tolerable only for short trips. We reckon the Ranger’s more accommodating rear stalls are significant in its sales leadership.

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.

With its 2150kg kerb weight and 3050kg GVM, the SR5 V-Active has a 900kg payload rating. It can also tow up to 3500kg of braked trailer but with its 5850kg GCM (or how much it can legally carry and tow at the same time) that would require a substantial 700kg reduction in payload to only 200kg, which could be used up by a driver and passenger alone. 

Alternatively, you could lower the trailer weight limit by the same 700kg to 2800kg (which is still a sizeable trailer) and retain the SR5’s maximum payload. We reckon most owners would do this anyway, given few (if any) would need to tow 3500kg.

The load tub is 1570mm long, 1645mm wide and 495mm deep with 1105mm between the wheel housings. Therefore, it can’t carry a standard Aussie pallet but will take a Euro-sized one. There are four load-anchorage points and we welcome the new lower/raise assistance for the hefty tailgate.

Cabin storage includes a large-bottle holder and bin in each front door, plus pop-out cupholders on either side of the dash, upper and lower glove boxes (with the upper having access to air-con) and an overhead glasses holder.

The latest centre console layout has a wireless phone-charging pad and vertical phone-storage slot, small-bottle/cupholder, a bin for small items and a box with padded lid that doubles as an elbow rest.

Rear passengers get a bottle-holder and bin in each door, pockets on each front seat backrest and a fold-down centre armrest with two more cupholders.

Only the narrower driver’s side of the 60/40-split rear seat base-cushion can swing up and be stored vertically as the passenger-side is now fixed, given the V-Active’s 48V battery resides beneath it and is ventilated by a louvered air intake in the passenger footwell.

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.

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 venerable (1GD-FTV) 2.8 litre four-cylinder turbo-diesel with V-Active produces the same 150kW and 500Nm as the standard engine, driving through a six-speed torque converter automatic.

However, Toyota claims fuel economy gains of up to 9.5 per cent when this drivetrain is combined with the new hybrid technology, which comprises a 48-volt electric motor-generator, 48-volt lithium-ion battery and idle-stop system.

The turbo-diesel engine uses a silent-belt to drive the motor-generator, which charges the battery under the rear seat. This battery, which Toyota claims weighs less than eight kilograms with 4.3Ah capacity, also supplies electricity to the vehicle’s 12-volt system through a DC/DC converter.

This system can send up to 8.4kW of power and 65Nm of torque through the motor-generator to assist the engine. Toyota claims this delivers smoother and quieter yet more responsive performance and reduces engine load under acceleration. It also results in a small reduction in idle speed from 720rpm to 600rpm.

Deceleration and braking energy are also recovered, converted into electricity and stored in the 48V battery for later use.  Toyota claims “hydraulic braking combined with regenerative braking creates a more effective and natural deceleration feel and supports downhill manoeuvring.”

The idle-stop system does not use the starter motor like conventional set-ups. Instead, the electric motor-generator, which is permanently connected to the engine via its belt-drive, delivers this function with greater smoothness and quietness.

Idle-stop duration can also be extended by the driver and, when restarting the engine on inclines, the idle-stop system retains brake pressure until enough drive force is generated to ensure smooth acceleration.

In another first for HiLux, its part-time, dual-range 4x4 system (with switchable rear diff-lock) in V-Active variants is paired with 'Multi-Terrain Select' to enhance off-road ability.

The driver can switch between six traction control settings tailored to suit a variety of terrain including 'Auto', 'Sand' and 'Mud' (high- and low-range), 'Deep Snow' and 'Dirt' (high-range) and Rock (low-range).

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.
 

We completed a total distance of 580km, which comprised a mix of city and suburban driving with an empty load tub and up to four adults on board, plus some freeway/highway running with a near-maximum payload.

When we stopped to refuel at the end of our test, the dash display was claiming average combined consumption of 9.5L/100km, which was lineball with our own 9.4 figure calculated from fuel bowser and tripmeter readings.

Both are higher than Toyota’s official 7.2L/100km figure but within the usual 2.0-3.0L/100km discrepancy between OEM ratings and real-world figures.

Interestingly, the last time we tested a 4x4 SR5 auto dual cab ute (without V-Active) in 2023, using similar routes and payloads, we achieved 9.6L/100km. So, the V-Active’s drop in consumption was only about 2.0 per cent, compared to Toyota’s claim of up to 9.5 per cent.

So, based on our real-world figure, you could expect a useful driving range of around 870km from its 80-litre tank.

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.

If you’re expecting a tangible difference in performance with the V-Active system, you’ll probably be disappointed. Fact is, after almost 600km of testing, on a variety of roads with a variety of loads, we could not detect any noticeable gain in acceleration, braking or smoothness compared to a standard SR5.

That’s not to say the V-Active system is not delivering up to 8.4kW of power and 65Nm of torque, as Toyota claims. It’s just that these gains are modest and delivered so discreetly that they are undetectable in real-world driving.

This was perhaps best demonstrated when we loaded 650kg into the load tub, which when combined with our two-man crew was a total payload of 830kg. That was only 70kg shy of the payload limit.

It made light work of our 13 per cent gradient 2.0km set climb at 60km/h by self-shifting down to fourth gear at 2250rpm, where it tapped maximum torque to easily haul this payload to the summit.

However, in our previous test of a standard SR5, on the same incline with 100kg more payload, the gear selection and engine rpm were the same as the V-Active. The same applied to engine-braking on the way down.

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.

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.

Toyota covers the HiLux with a five-year/unlimited km warranty which is par for the course in the mainstream market.

Service intervals are relatively short at six months/10,000km whichever occurs first. Capped-price servicing for the first five years/100,000km totals $3889 or an average of $779 per year.

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.
