Mercedes-Benz GLE-Class vs Lexus LX

What's the difference?

There’s little wonder the GLE63 S is back for a second go around, after  clearly putting the frighteners on the Audi RS Q8 and BMW’s X5 M Competition and X6 M Competition.

After all, it’s a large SUV that sacrifices little in the way of practicality (especially the wagon) in its pursuit of high performance.

And for that reason, we’re itching to go for another drive – with or without the family.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

The Lexus LX500d is a genuine seven-seater with impressive levels of refinement, comfort and even off-road capability.

The interior borders on being chintzy and it’s price-tag is the wrong side of bloody expensive, but there's no denying this Lexus is packed with stuff.

It’s more city than country, more bling than bush tourer – it’s like a tarted-up 300 Series – but that’s absolutely fine for the people who buy these.

I wouldn’t blame anyone for cross-shopping a Toyota LandCruiser 300 Series with this – and then opting for the 300 Series! For one thing, you’ll save a stack of cash.

First things first, the new GLE63 S is available in two body-styles, with the wagon appealing to the traditionalists out there, while the coupe targets the style-conscious.

Either way, few large SUVs are as imposing as the GLE63 S, which is a good thing considering it wants to be taken seriously.

Up front, it’s immediately identifiable as a Mercedes-AMG model thanks to its distinctive Panamericana grille insert.

The angry look is punctuated by the angular daytime running lights integrated into the Multibeam LED headlights, while the chunky front bumper has large air intakes.

Around the side, the GLE63 S stands out with its aggressive wheelarch extensions and side skirts, with the wagon getting 21-inch alloy wheels as standard, while the coupe gets 22-inch items.

From the A-pillars onwards, the differences between the wagon and coupe body-styles start to become apparent, with the latter’s roofline much more steeply raked.

At the rear, the wagon and coupe differentiate themselves even more clearly with their unique tailgates, LED tail-lights and diffusers. That said, they do have a sports exhaust system with squared-off quad tailpipes in common.

It’s worth mentioning that the difference in body-style also means a difference in dimensions, with the coupe 7mm longer (4961mm) than the wagon, despite having a 60mm-shorter wheelbase (2935mm). It’s also 1mm narrower (2014mm) and 66mm shorter (1716mm).

Inside, the GLE63 S separates itself with its flat-bottom steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are upholstered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

The door bins are of the hard plastic variety. That’s underwhelming in a vehicle that costs this much, as you would hope cow hide – or at least a soft-touch material – would be applied to them.

The black headliner acts as another reminder of its performance focus, and while it makes for a darker cabin, metallic accents feature throughout, while the trim (our test vehicle had open-pore wood) adds some variety alongside the ambient lighting.

That said, the GLE63 S is still filled to the brim with cutting-edge technology, including two 12.3-inch displays, with one the central touchscreen and the other a digital instrument cluster.

Both use Mercedes’ MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up is still the benchmark, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.

In firmly keeping with its target market, the LX500d is a premium-looking SUV.

This is a big unit and everything is slick and in-your-face impressive. Inside and out this Lexus looks a lot like a tarted-up LandCruiser 300 Series that’s been on a recent cycle of steroids. 

The optional 22-inch alloy wheels (part of the $5500 Enhancement Pack, as mentioned above) add to the overall look. 

The interior is a tasteful blend of woodgrain, leather accents, soft-touch surfaces, plush seating, and even comfortable arm-rests.

Being a large SUV, you’d expect the GLE63 S to be quite practical, and it is, but what you wouldn’t expect is the coupe to have 25L more cargo capacity than the wagon, at a generous 655L, due to its higher window line.

That said, when you stow the 40/20/40 split-fold rear bench via the second row’s release latches, the wagon has a significant 220L advantage over the coupe, at a cavernous 2010L, thanks to its boxier design.

Either way, there’s a small load lip to contend with, making loading bulkier items a little more difficult, although that task can be made easier with the flick of a switch, as the air springs are able to lower the load height by a handy 50mm.

Better yet, four tie-down points are on hand to help secure loose items,  alongside a couple of bag hooks, while a space-saver spare resides under the flat floor.

In the second row, things are even better, with the wagon offering a crazy amount of legroom behind our 184cm driving position, as well as two inches of headroom for me.

With its 60mm-shorter wheelbase, the coupe naturally sacrifices some legroom, but it still provides three inches of legroom, while its sloping roofline trims headroom to an inch.

No matter the body-style, the five-seat GLE63 S is wide enough to seat three adults abreast with few complaints, with the transmission tunnel on the smaller side, meaning there’s plenty of room for feet.

There’s also plenty of room for child seats, with two ISOFIX and three top-tether anchorage points on hand for fitting them.

Amenities-wise, rear occupants are treated to map pockets on the front-seat backrests, as well as a fold-down armrest with two cupholders, while the door bins can accommodate a couple of regular bottles each.

A  fold-out cubby is positioned below the air vents at the rear of the centre console, containing two slots for smartphones as well as a pair of USB-C ports.

In the first row, occupants have access to the centre console’s cubby, which features two temperature-controlled cupholders, in front of which are a wireless smartphone charger, two USB-C ports and a 12V power outlet.

The central storage bin is pleasingly large and contains another USB-C port, while the glovebox is also on the larger side, and you get an overhead sunglasses holder too. Stunningly, the front door bins can take three regular bottles apiece. Not bad.

While the wagon has a large, square rear window, the coupe’s is a letterbox in comparison, so rearward visibility isn’t one of its strong suits.

Everyone is well catered for inside this Lexus, in terms of, well, everything.

The tech is easy to use – it was simple enough to get Apple CarPlay working – and the screens are big: the horizontal 12.3-inch multimedia unit upfront, an 8.0-inch screen (to monitor air-con, air-suspension height, the four-wheel-drive system, and other vehicle information), a head-up display, plus a 7.0-inch touchscreen for rear passengers.

Heating and cooling are via the 'climate concierge' and everyone can keep themselves as comfortably hot or cold as they like with separate controls.

Storage is plentiful with the usual array of door pockets, cupholders, big glove box etc, but there’s also a cavernous centre console (with multiple ways to open the lids) as well as map pockets for the second row, cup-holders in the centre fold-down armrest and even cupholders for the third row.

The Lexus has a Qi wireless charger as well as front and rear USB-C charging ports – one upfront, two in the second row, and two in the third row – so that should keep any whinging about devices to a minimum – but, knowing kids, it probably won’t. 

There’s also a 12V DC socket (front and rear) and a 220V socket in the rear cargo area.

Power-adjustable seats upfront make life easy for the driver and front passenger and these pews are as good as what I’d imagine a massage chair is like. Even the second row is on the right side of plush, but the third row is not quite there.

Second-row passengers have their own air con and entertainment controls, and there’s also an HDMI port.

The moon roof – an Enhancement Pack inclusion – is power-adjustable and allows plenty of welcome natural light in through the top.

In terms of packability, the Lexus LX500d has a claimed 174L (VDA) of cargo space when seven seats are in use; 982L when five seats are being used (that’s with the power-folding third row stowed flat at the push of a button); and 1871L when all seats are stowed away (the 60:40 folding second-row seats tumble-fold forward), except for the driver and front passenger. 

The boot has a 220V power outlet.

As mentioned the seven-seat Lexus LX500d is the entry-level variant in the Lexus LX line-up. 

The standard features list is comprehensive but, for the sake of brevity, we’ll rattle off only a handful of them including a 12.3-inch multimedia touchscreen (with Apple CarPlay and Android Auto, and Bluetooth), a 25-speaker Mark Levinson sound system, heated and ventilated power-adjustable seats, woodgrain steering wheel trim, 8.0-inch multi-information display, quad-zone climate control, 7.0-inch touchscreen and separate control panel for rear passengers, multi-terrain monitor with panoramic view, and 20-inch alloy wheels.

It also has a digital rear-view mirror, adaptive variable suspension, and active height control with low, normal and two high settings.

The Lexus LX500d retails for $153,091 (excluding on-road costs). Our test vehicle has an optional Enhancement Pack (which includes 22-inch alloy wheels, moonroof, hands-free power boot with kick sensor, $5500) and has been fitted with a towbar ($1545). The total price of this vehicle as tested is $160,136 (excluding on-road costs).

Exterior paint colours include the no-extra-cost 'Onyx' or any of these – 'Liquid Metal', 'White Nova' (F Sport models only), 'Sonic Quartz' (not available on F Sport models), 'Titanium', 'Graphite Black', and 'Khaki Metal' (on our test vehicle) – all of which incur an extra cost.

The GLE63 S is powered by Mercedes-AMG’s ubiquitous 4.0-litre twin-turbo V8 petrol engine, with this version pumping out a hard-hitting 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

But that’s not all, because the GLE63 S also has a 48V mild-hybrid system called EQ Boost.

As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of electric boost in short bursts, which means it can also reduce the sensation of turbo lag.

Mated to a nine-speed torque-converter automatic transmission with paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the GLE63 S sprints from a standstill to 100km/h in just 3.8 seconds, in either body-style.

The Lexus LX500d has a 3.3L V6 twin turbo-diesel engine, producing 227kW at 4000rpm and 700Nm between 1600-2600rpm.

It has a 10-speed automatic transmission with manual shift mode, a full-time all-wheel-drive system, low-range transfer case and locking diffs. 

The V6 is impressive and this is a smooth-shifting beast, but there’s a real lazy – not lively – feel to how the engine and auto work.

It’s pretty hefty as well – with a listed 2690kg kerb weight – so the Lexus takes a bit of a wind-up to get going off the mark and during overtaking moves.

The GLE63 S’s fuel consumption on the combined-cycle test (ADR 81/02) varies, with the wagon achieving 12.4L/100km, while the coupe needs 0.2L more. Carbon dioxide (CO2) emissions are 282g/km and 286g/km respectively.

When you consider the high level of performance on offer, all of these claims are fairly reasonable. And they’re made possible by the engine’s cylinder-deactivation technology and the 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.

That said, in our real-world testing with the wagon, we averaged 12.7L/100km over 149km. While that’s a surprisingly good result, its launch drive route mainly consisted of high-speed roads, so expect a much higher number in metropolitan areas.

And in the coupe, we averaged a higher but still respectable 14.4L/100km over 68km, although its launch  route purely involved high-speed country roads, and you know what that means.

For reference, the wagon has an 80L fuel tank, while the coupe has an 85L unit. Either way, the GLE63 S only takes more expensive 98RON premium petrol.

The Lexus LX500d seven-seater has a listed fuel consumption of 8.9L/100km on a combined cycle.

Our actual fuel consumption on this test, from pump to pump, was 13.2L/100km. Note: our test included a lot of low-range 4WDing. 

The LX500d has an 80-litre fuel tank – so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 606km or so. Take off a 30km safe-distance buffer and you have 576km.

Make no mistake, the GLE63 S is a big beast, but it certainly doesn’t act its size.

Firstly, the GLE63 S’s engine is an absolute monster, helping it to hunker down off the line and then charge on towards the horizon with serious vigour.

While there’s so much initial torque to begin with, you still get the added benefit of the ISG, which helps to eliminate lag as the new twin-scroll turbos spool up.

That said, acceleration isn’t always brutal, as the electronic stability control (ESC) is often quick to cut power when under full throttle in  first gear. Thankfully, engaging the ESC system’s Sport mode solves this issue.

This behaviour is somewhat ironic as the 4Matic+ system is seemingly never short of grip, with it's working hard to find the axle with the most traction, while torque vectoring and a rear limited-slip differential proportion torque from wheel to wheel.

Regardless, the transmission provides predictably smooth and predominantly timely gear changes, although they’re definitely not dual-clutch quick.

What’s more memorable, though, is the sports exhaust system, which keeps your neighbours relatively sane in the Comfort and Sport drive modes, but will drive them mad in Sport+, with hilarious crackles and pops heard loud and clear on the overrun.

It’s worth noting that while the sports exhaust system can be manually engaged in the Comfort and Sport drive modes via a switch on the centre console, it only makes the V8 rumble grow stronger, with the full effect only unlocked in Sport+.

Of course, there’s more to the GLE63 S experience, like the fact that  it somehow rides like a large SUV yet handles like a sports car.

The suspension’s air springs and adaptive dampers offer up a luxurious ride in the Comfort drive mode, with the GLE63 S wafting along with confidence. Not even its large-diameter alloy wheels pose too much of a threat to this quality on poorer country roads.

The ride is still more than liveable in the Sport drive mode, although the adaptive dampers become a  too firm in Sport+, with the ride becoming a little too jittery to be bearable.

Of course, the whole point of the adaptive dampers becoming progressively firmer is to help the GLE63 S handle even better, but the real revelations here are the active anti-roll bars and engine mounts, which effectively limit body roll to such a level that it’s almost imperceptible.

In fact, overall body control is impressive, with the GLE63 S not feeling like the 2.5-tonne-plus behemoth it is. It really has no right to attack corners the way it does, with the coupe feeling a touch tighter than the wagon, thanks to its 60mm-shorter wheelbase.

Further confidence is afforded by the sports brakes, which include 400mm discs with six-piston calipers up front. Yep, they wash away speed with ease, which is exactly what you’d hope for.

Also key to the handling is the electric power steering, which is speed-sensitive and has a variable ratio. It’s really quick in the wagon, and even more so in the coupe, thanks to its more direct tune.

Either way, this set-up is well-weighted in the Comfort drive mode, with plenty of feel and just the right amount of heft. That said, Sport and Sport+ make it gradually heavier, but neither make the driving experience better, so stick with the default setting.

Meanwhile, Noise, Vibration and Harshness (NVH) levels are pretty good, although tyre roar is consistent at highway speeds, while wind whistle is prominent over the side mirrors when travelling above 110km/h.

The Lexus is a refined and comfortable vehicle on sealed surfaces.

It’s 5100mm long (with a 2850mm wheelbase), 1990mm wide (with a 1675mm wheel track, front and back), 1895mm high, and it has a 2690kg kerb weight.

The woodgrain steering wheel feels nice in the hands but even though the Lexus feels tighter and more controlled than the previous-gen – its body-on-frame structure has shed some kegs – this is a hefty rig so it’s no real surprise that body roll remains pronounced – it always tends to wallow even at optimal ride height. 

The suspension set-up – adjustable dampers, double wishbones at the front, a four-linkage rigid axle at the rear, stabiliser bars front and rear – is aimed at keeping things under control, and it certainly irons out any major issues, but it’s not perfect, even ably supported by adaptive variable suspension.

The brake pedals feel spongy, taking some time to ‘bite’, but the ventilated disc brakes front and rear did pull the Lexus to a controlled stop when I did a “watch out for that roo!” emergency-braking move.

And while, by its very nature, it may not be a very dynamic SUV to drive, its low-key composure makes up for that.

The gutsy V6 and auto work well, if lazily, together, and while that transmission is enough of a smooth shifter, 10 gear ratios seems like overkill to me.

Driving modes include normal, eco, sport and each adjusts throttle response, engine outputs, and gearshifts to suit the driver and the driving conditions.

It’s quiet inside – very quiet – and there’s no issues with vibration or harshness levels either.

Among its many tech-based attractions, the digital rear-view mirror is a handy touch.

This is a great open-road touring vehicle but with some flaws when it comes to adventuring off-road.

Our test vehicle is shod with Dunlop Grandtrek 265/50R22 112V tyres and these all-season tyres are fine for sealed surfaces, but they’re not up to low-range 4WDing in tough conditions, even more so on these 22-inch rims, as we found out during a few hours at our 4WD testing ground.

The Lexus has Cruiser-like off-road-capable underpinnings with top-layer dirt-focussed tech as well. 

There’s plenty of glass around so visibility is fine, steering generally feels light but takes on a clinical precision during low-speed, low-range 4WDing.

And ‘clinical’ is how the Lexus feels off-road – not always in a good way either. Like many contemporary tech-heavy off-roaders nowadays, it’s almost so good that you’re in danger of feeling entirely removed from the actual process of driving.

With multi-terrain select driving modes offering auto, dirt, sand, mud, deep snow, and rock options; with a multi-terrain monitor and panoramic view helping you ‘see’ everywhere that you usually wouldn’t be able to see on the track; with active height control helping you to lift the vehicle’s body in order to improve off-road angles at the push of a button; and the list goes on. 

That’s not forgetting downhill assist control, hill-start assist, crawl control, and off-road traction control.

Don’t get me wrong: high-tech is great because anything that helps maintain safe forward progress out bush or while beach driving is awesome but, Great Odin’s raven, it’d be great if the tech onslaught stops now. As if that’s going to happen.

If you’re looking to tow with your Lexus, listen up: unbraked towing capacity is 750kg, braked towing capacity is 3500kg. It has a gross vehicle mass of 3280kg and a gross combination mass of 6780kg. There you go.

It has a full-size spare tyre and that’s mounted under the rear cargo area.

The Lexus does not have an ANCAP safety ratings as it has not been tested yet.

Safety features include 10 airbags (driver and front passenger: front, knee, side; rear: side), AEB with pedestrian detection and daytime cyclist detection, front and rear parking sensors, reversing camera with rear camera washer, adaptive cruise control, road sign assist, blind spot monitor with rear cross traffic alert, tyre pressure warning system, and more.

Buying a Lexus gives you three-year access to Lexus Connected Services including (SOS) emergency calls, automatic collision notification, and stolen vehicle tracking.

As with all Mercedes-AMG models, the GLE63 S 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.

Better yet, the GLE63 S’s service intervals are relatively long, at every year or 20,000km – whichever comes first.

It’s also available with a five-year/100,000km capped-price-servicing plan, but it costs $4450 in total, or an average of $890 per visit. Yep, the GLE63 S isn’t exactly cheap to maintain, but you expected that.

The Lexus LX500d has a five-year/unlimited-kilometre warranty.

Capped-price servicing applies for three years. Servicing is set at six month/10,000km intervals with each appointment costing $595 over that period.

Lexus Encore Platinum benefits – including valet parking and on-demand vehicle loans – are standard for new Lexus owners.
