Mercedes-Benz GLS vs Lexus ES250

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…

Since day one Lexus has aimed to prise buyers away from the limpet-like grip of traditional luxury car players. Conventional marketing wisdom says consumers buy brands, with the actual product a secondary consideration. 

The updated ES has the value, efficiency, safety, and driving refinement to again challenge the establishment. Amazingly, the ownership package, specifically the warranty, is starting to lag the market. 

But for open-minded premium buyers this product is worth a look before following a well-worn brand path. And if it was my money, the ES 300h Luxury with Enhancement Pack is the range sweet spot for value and performance.

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.

From shy wallflower to life of the party, the Lexus ES was given a comprehensive design makeover for its seventh generation.

A dramatic, angular exterior incorporates signature elements of the Lexus brand's distinctive design language including an unmissable ‘spindle grille’, but is still clearly recognisable as a conventional 'three-box’ sedan.

The jagged headlights now feature ‘tri-beam’ LEDs on F Sport and Sports Luxury grades, adding an extra air of purpose to an already bold face. And the grille on Luxury and Sports Luxury models is now made up of multiple L-shaped elements, mirrored across the top and bottom sections, then finished in gunmetal grey for a close to 3D effect.

The ES is offered in 10 colours - ‘Sonic Iridium’, ‘Sonic Chrome’, ‘Sonic Quartz’, ‘Onyx’, ‘Graphite Black’, ‘Titanium’, ‘Glacial Ecru’, ‘Radiata Green’, ‘Vermillion’ and ‘Deep Blue’ with two other shades reserved for the F Sport only - ‘White Nova’ and ‘Cobalt Mica.’

Inside, the dash is a mix of simple sweeping surfaces contrasted by a flurry of activity around the centre stack and instrument cluster.

Located roughly 10cm closer to the driver, the new multimedia screen is a 12.3-inch unit with touch functionality, a welcome alternative to the laggy and inaccurate Lexus ‘Remote Touch’ trackpad set-up. Remote Touch remains, but my advice is to ignore it and use the touchscreen.

The instruments sit in a deeply hooded binnacle with buttons and dials on and around it. Not the sleekest design in the segment and passable only from an ergonomic point-of-view, but the overall feel is suitably premium.

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.

An overall length just under 5.0m long shows how much the ES and its competitors have crept up in size over recent generations. The Merc C-Class is more a mid-size car than the compact sedan it once was, and at nearly 1.9m wide and standing a bit over 1.4m tall the ES more than matches it for space.

There's plenty of room up front, the car feeling open and spacious from behind the wheel, thanks in part to the low sweep of the dash. And the rear is just as commodious.

Sitting behind the driver's seat set for my 183cm (6'0”) position I enjoyed good leg and toe room, with more than enough headroom, despite inclusion of a tilt and slide glass sunroof on all models.

Not only that, entry to and egress from the rear is a breeze thanks to a large aperture and wide opening doors. And while the back seat is best for two, three adults across is do-able without too much pain and suffering for short to medium journeys.

Connectivity and power options are plentiful with twin USB ports and a 12-volt socket front and rear. And storage starts with two cupholders in the front centre console, and another pair in the fold-down rear centre armrest.

If the remote touch system was (deservedly) given the boot, there would be room for extra oddments space in the front console.

The front door pockets are adequate rather than large (smaller bottles only), the glove box is modest, but the storage box (with padded armrest lid) between the front seats is more generous.

There are adjustable air vents for rear passengers, which you'd expect in this category, but are always a plus none-the-less.

The rear door pockets are okay, except the opening is relatively slim so bottles are a struggle, but there are map pockets on the back of both front seats as another bottle option.

Important to note that while boot space is decent at 454 litres (VDA) the rear seat doesn't fold. At all. A lockable ski port door sits behind the rear armrest, but the lack of a split-folding back seat is a significant practicality compromise.

A reasonably high loading lip into the boot isn't great, either, but there are tie-down hooks to help secure loose loads.

The Lexus ES is a no-tow zone and a space-saver spare is your only flat tyre option.

The existing ES 300h (the ‘h’ denoting hybrid) is now joined by a non-hybrid model using the same petrol engine, tuned specifically to run without the support of an electric motor.

The pre-update, hybrid-only ES line-up spanned six model variations across a roughly $15K price spread from the ES 300h Luxury ($62,525) to the ES 300h Sports Luxury ($77,000).

Now there are five models with an ‘Enhancement Pack’ (EP) available on three of them, for an effective range of eight grades. Again, it's a $15K spread, stretching from the ES 250 Luxury ($61,620, before on-road costs) to the ES 300h Sports Luxury ($76,530).

Let's kick-off with the ES 250 Luxury. Aside from the safety and powertrain tech covered later in the review, the ‘entry-level’ grade is loaded with standard features including, 10-way power-adjustable and heated front seats, dual-zone climate control air, active cruise control, a new 12.3-inch multimedia touchscreen, satellite navigation (with voice control), keyless entry and start, 17-inch alloy wheels, a glass sunroof, auto rain-sensing wipers, plus 10-speaker audio with digital radio, as well as Apple CarPlay and Android Auto compatibility. The steering wheel and gearshift are leather-trimmed, while the seat trim is synthetic leather.

An Enhancement Pack adds wireless phone charging, privacy glass, a colour head-up display, and $1500 to the price tag (total $63,120).

The next rung up the price ladder brings the hybrid powertrain into play, so the ES 300h Luxury ($63,550) retains all the features of the ES 250 Luxury EP and adds a rear spoiler and power adjustable steering column.

Opting for the ES 300h Luxury EP then adds a power boot lid (with kick sensor), leather-accented trim, 18-inch rims, panoramic view monitor (overhead and 360-degree), 14-way power driver's seat (with memory settings), ventilated front seats, side blinds and a power rear sunshade, as well as $8260 to the price (total $71,810).

Next, as the name implies, two ES F Sport models dial up the performance personality.

The ES 250 F Sport ($70,860) retains the features of the ES 300h Luxury EP (except side blinds) while adding LED headlights with adaptive high-beam, a ‘wire-mesh’ grille, sports body kit, 19-inch wheels, performance dampers, an 8.0-inch driver display, alloy interior accents and grippier F Sport seats.

Stump up for the ES 300h F Sport ($72,930) and you'll ride on an adaptive suspension system with two driver-selectable settings, Go one step further and select the ES 300h F Sport EP ($76,530) and you'll also be cranking up a 17-speaker Mark Levinson audio system and warming your hands on a heated steering wheel.

Then, the top-of-the ES pyramid, the 300h Sports Luxury ($78,180), puts it all on the table adding top-shelf semi-aniline leather-accented trim, power adjustable, reclining, and heated rear outboard seats, tri-zone climate control, as well as side door blinds and a power rear sunshade. The rear centre armrest also features controls for the sunshade, seat heating (and angle), as well as audio and climate settings.

That's a lot to take in, so here's a table to help clarify the model walk-up. But suffice it to say this ES maintains Lexus’ reputation for value, testing its competitors in the luxury sedan space.

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 ES 250 is powered by an all-alloy, 2.5-litre, naturally aspirated (A25A-FKS) four-cylinder engine featuring DVVT (Dual Variable Valve Timing) - electrically actuated on the intake side, and hydraulically on the exhaust side. It also uses a combination of direct and multi-point fuel-injection (D-4S).

Maximum power is a handy 152kW at 6600rpm and peak torque of 243Nm is available between 4000-5000rpm, with drive going to the front wheels via an eight-speed automatic transmission.

The 300h features a modified (A25A-FXS) version of the same engine using the Atkinson combustion cycle which plays with valve timing to effectively shorten the intake stroke and lengthen the expansion stroke.

The down-side of this set-up is a loss of low-end power, while the up-side is improved fuel efficiency. Which makes it perfect for a hybrid application where an electric motor can make up for the low-end shortfall.

Here, the result is a combined output of 160kW, with the petrol engine producing its peak power (131kW) at 5700rpm.

The 300h's motor is a permanent magnet synchronous type producing 88kW/202Nm, and the battery is a 204-cell nickel-metal hydride type with a capacity of 244.8 volts.

Drive again goes to the front wheels, this time via a continuously variable transmission (CVT).

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.

Hyundai's official fuel economy figure for the ES 250, on the ADR 81/02 - urban, extra-urban cycle, is 6.6L/100km for the Luxury and 6.8L/100km for the F-Sport, the 2.5-litre four emitting 150 and 156g/km of C02 (respectively) in the process.

The official combined cycle fuel economy figure for the ES 350h, is just 4.8L/100km, the hybrid powertrain emitting only 109g/km of C02.

While the launch program didn't allow us to capture real-world (at the bowser) figures we did see a dash-indicated average of 5.5L/100km in the 300h, which is brilliant for a car in this class, weighing in at 1.7 tonnes.

You'll need 60 litres of 95RON premium unleaded to fill ES 250's tank and 50 litres to brim the ES 300h. Using Lexus figures that equates to a range of a little less than 900km in the 250 and just over 1000km in the 350h (900km using our dash-indicated number).

To further sweeten the fuel economy equation Lexus provides an Ampol/Caltex five-cents-per-litre discount as a permanent offer via the Lexus app. Nice.

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 first thing you notice behind the wheel of this ES is how extraordinarily quiet it is. Sound absorption materials are stuffed all around the body. Even the engine cover has been designed to keep the decibels down.

And ‘Active Noise Control’ (ANC) uses the audio system to generate “noise-cancelling waves” to suppress mechanical clatter from the engine and transmission. The car is eerily EV-like in it's pin-drop interior tranquility.

We focused on the ES 300h for the launch drive, and Lexus claims 0-100km/h 8.9sec for this version of the car. It feels every bit that quick, but the engine ‘noise’ and exhaust note are like the humming of a distant bee hive. With thanks to Daryl Kerrigan, how's the serenity?

Around town the ES is composed and supple, absorbing pock-marked urban irregularities with ease, and on the freeway it feels like a hovercraft.

Lexus makes a lot of noise about the torsional stiffness of the ‘Global Architecture-K’ (GA-K) platform sitting under the ES, and it's clearly more than hot air. Through twisting B-roads it remains balanced and predictable.

Even in non-F-Sport variants the car points nicely and will steer accurately on the throttle through constant radius corners, with only modest body roll. The ES doesn't feel like a front-wheel drive car, with neutral handling up to an impressively high limit.

Luxury and Sports Luxury grades are offered with three drive modes - ‘Normal’, ‘Eco’ and ‘Sport’, tweaking engine and transmission settings for economy or a more spirited drive.

ES 300h F Sport variants add three more modes - ‘Sport S’, ‘Sport S+’ and ‘Custom’, further revising engine, steering, suspension and transmission characteristics.

Despite all the tuning options, road feel is not the ES's strongest suit. Dialing in sportier modes will add steering weight but no matter what the setting, the connection between the front wheels and the driver's hands is less than intimate.

The CVT auto suffers some of that disconnect between road speed and revs, the engine moving up and down the rev range in search of the power/efficiency sweet spot. But wheel-mounted paddles allow for manual shifting through pre-set ‘ratio’ points, and that option works nicely if you prefer to take the reins.

And when it comes to slowing down the ‘Auto Glide Control’ (ACG) system smooths out regenerative braking when you're coasting to a stop.

The conventional brakes are ventilated (305mm) discs at the front and a solid (281mm) rotor set-up at the rear. Pedal feel is progressive and outright stopping power is strong.

Random notes: The front seats are great. Super-comfortable yet neatly bolstered for secure location. The F Sport's chairs, even more so. The new multimedia touchscreen is a winner. It looks good and menu navigation is agreeably straight forward. And the digital instrument cluster is similarly clean and clear.

The Lexus ES scores a maximum five-star ANCAP rating, the car first assessed in 2018, with updates in 2019 and September 2021.

It received high ratings against all four key criteria (adult occupant protection, child occupant protection, vulnerable road user protection, and safety assist systems).

Active crash-avoidance technology on all ES models includes, a pre-collision safety system (Lexus-speak for AEB) active from 10-180km/h, with pedestrian and daytime cyclist detection, dynamic radar cruise control, road sign assist, lane tracing assist, fatigue detection and reminder, tyre pressure monitoring, a reversing camera, as well as rear cross-traffic alert and parking support brake (including an intelligent clearance sonar).

Other features like blind-spot monitoring, adaptive high-beam and a panoramic view monitor are included on F Sport and Sport Luxury grades.

If a crash is unavoidable there are 10 airbags on-board - dual front, driver and front passenger knee, front and rear side airbags and side curtain airbags covering both rows.

There's also an active bonnet to minimise pedestrian impact injuries, and ‘Lexus Connected Services’ includes an SOS call (driver-activated and/or automatic), and stolen vehicle tracking.

For child seats there are top tethers for all three rear positions with ISOFIX anchors on the outer two.

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.

From the time it arrived in the Australian market just over 30 years ago Lexus has made the ownership experience a key differentiator for the brand.

Its focus on post-purchase benefits and ease of servicing shook the established luxury players out of their button-backed leather lounge slumber and into a new aftersales mindset.

That said, the Lexus standard four-year/100,000km warranty is some way off luxury newcomer, Genesis, as well as traditional heavyweights Jaguar and Mercedes-Benz, all at five years/unlimited km.

Yes, Audi, BMW and others are at three years/unlimited km, but the game has moved on for them, too. Plus, the mainstream market standard is now five years/unlimited km, with some at seven, even 10 years.

On the other hand, the ‘Lexus Encore Privileges’ program provides 24-hour roadside assistance for the duration of the warranty, as well as, “dining, hotel partnership and luxury lifestyle experience offers exclusive to owners of new Lexus vehicles.”

The Lexus Enform smartphone app also offers access to everything from real-time advice on events and the weather to nav destinations (restaurants, businesses, etc), and more.

Service is scheduled every 12 months/15,000km (whichever comes first), and the first three (capped price) services for the ES are $495 each.

A Lexus loan car is provided while your pride and joy is in the workshop, or a pick-up and return option (from home or office) is available. You'll also receive a complimentary wash and interior vacuum.
