Mercedes-Benz GLS vs Renault Scenic E-Tech

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 Renault Scenic E-Tech is lining up against some heavy-hitting competitors, but Renault Australia admits it has one top of mind - the Kia EV5. The Kia’s a quality package and if you’re in the market for a mid-size electric SUV, you’ll no doubt have it on your shopping list. And you should have a look at this slightly smaller car, as well. It has the refinement, practicality and safety to stand up confidently in a rapidly expanding segment.

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

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.

There are some design tips of the hat to Scenics past in this latest electric version, including blacked-out door pillars and a recognisably angular C-pillar treatment.

But despite the fact it debuted at the Munich IAA Motor Show in late 2023, from its slimline headlights and jagged grille to its sculpted flanks and saw tooth rear end, this fifth-generation Scenic looks contemporary from every angle.

A highlight is the large Renault diamond logo sitting at the centre of a faux upper grille, surrounded by a multitude of the same elongated hexagon shape as a cool recurring graphic, the pattern merging neatly into the headlights.

Speaking of which, the LED beams can be set to produce an elaborate welcome sequence as you approach the car.

The interior feels slick and screen-rich but not at the expense of user-friendly physical controls for audio, ventilation and other commonly used functions.

Recycled fabric on the dashboard and headliner looks and feels good while doing its bit to suppress cabin noise.

Speaking of which, the Scenic is Renault’s poster child for the use of recycled materials in its construction and end of life recyclability.

Everything from ferrous components consisting of 37 per cent recycled materials to a bonnet and doors made of up to 80 per cent recycled aluminium.

The dashboard cowling is made from kenaf, a plant fibre similar to jute; the steering wheel cover is 51 per cent bio-sourced; the cockpit uses 26 per cent recycled plastic; the storage bins in the door panels are 45 per cent recycled fibre, the floor mats are 54 per cent recycled plastic bottles and the seat upholstery is 100 per cent recycled fabric. The list goes on and on, but you get the idea.

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.

In terms of how it all works in practice, at just under 4.5m long, close to 1.9m wide and less than 1.6m tall with a 2785mm wheelbase, the Scenic is more compact than the larger BYD Sealion 7 or Zeekr 7X, for example.

But there’s plenty of breathing room up front, with the centre screen angled towards the driver enhancing the cockpit feel for the one doing the steering.

There are large carpeted bins in the doors with room for bottles and a lidded storage box between the seats doubles as a centre armrest. That lid slides forward by 70mm to cover a small storage cubby under the front of it, which is a handy trick.

Locating the gear selector on the right-hand side of the steering column liberates extra space for a centre cupholder and large console storage bin. There’s a generous glove box and a wireless smartphone charger under the centre screen includes a rubberised base and two lugs to stop devices sliding around. Power and connectivity runs to two USB-C ports and a 12-volt socket.

Moving to the second row, sitting behind my 183cm driving position, while toe room is a little tight (with the driver’s seat set low down), there’s heaps of leg and headroom as well as enough shoulder room (and foot room thanks to a flat floor) for three adults on short to mid-length trips. A pair of adjustable centre air vents is also a welcome inclusion.  

Storage includes door bins (again with room for bottles), large and device-sized pockets on the front seat backs and the pièce de résistance is the evocatively named ‘Ingenious armrest’, which includes a storage area and two cupholders at the base of articulated horizontal arms that allow passengers to mount a phone or tablet at various angles in rubberised slots for joint or solo viewing.

It is, indeed, ingenious and four USB-C plugs (two in the armrest, two near the air vents) mean back-seaters won’t be short of power options.

Boot volume with the rear seats upright is useful at close to 545 litres (VDA), expanding to around 1670L with the 40/20/40 split-fold second row lowered. A power tailgate is standard across the range.

There are bag hooks, tie-down anchors, lighting and a 12-volt socket back there, although for V2L (vehicle to load) functionality you’ll need an accessory adapter to plug into the charge port.

Maximum braked trailer towing capacity is a handy 1100kg, but there’s no spare tyre, only a repair/inflator kit, which isn’t good enough.

The Scenic E-Tech starts from $55,990, before on-road costs, for the entry-grade Techno. Then there’s the Techno Long Range for $59,990, BOC, while the flagship Esprit Alpine comes in at $65,990.

That’s sharp relative to competitors and follows the brand getting a reality check with the Megane E-Tech after it launched here in late 2024, Renault shaving $10,000 off its price only a few months later.

Equipment highlights across the line-up include a 12-inch multimedia touchscreen, a 12.3-inch driver display, sat-nav, adaptive cruise control, a 360-degree surround-camera view, all LED exterior lights, wireless Android Auto and Apple CarPlay and six-speaker Arkamys audio.

There’s also dual-zone climate control, an electric tailgate, auto-folding side mirrors, cloth upholstery, heated front seats and steering wheel, 48-colour ambient interior lighting, keyless entry and start and 19-inch alloys (on the Techno models).

Then you can fold in over-the-air updates, access to remote services via the ‘MyRenault’ app and Google In-Built that enables voice-control for up to 70 car functions.

The Esprit Alpine ups the ante with 20-inch rims, nine-speaker Harman Kardon audio, synthetic leather and cloth seat trim, six-way power adjustment (with memory settings) for driver and front passenger seats, a massaging driver’s seat, brushed metal pedal covers and facial recognition for seat and mirror settings.

In short, the Scenic is well-equipped relative to its competitive set and cost of entry, with Renault confirming there are mainly demonstrator cars in dealers at the moment, with the majority of stock landing in late May or early June this year.

There are three optional paint choices - metallic ($800), two-tone ($1000) and matt ($1200), the latter exclusive to the Esprit Alpine.

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.
 

Like its Megane E-Tech sibling, the Scenic E-Tech uses an excited synchronous motor which Renault says is more efficient than the more commonly used permanent magnet type, with the bonus that it uses no rare earth materials.

The entry-level Scenic E-Tech Techno's fitted with a 60kWh NMC battery. Its electric motor transfers 125kW and 280Nm to the front wheels and Renault claims a 0-100km/h time of 8.6 seconds.

The Techno Long Range and top-spec Esprit Alpine pack an 87kWh battery and a more powerful motor, raising outputs to 160kW/300Nm and lowering the 0-100kmh sprint time to 7.9 seconds.

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.

Official energy consumption numbers for the combined (urban/extra-urban) cycle are close between the two powertrains at 16.3kWh/100km for the Techno and 16.8kWh/100km for the Techno Long Range and Esprit Alpine, which are bang on average for the class.

Range for the standard Techno is 430km, which is at the lower end of expectations for a medium electric SUV but adding the bigger battery pushes that number out to 625km, which is much healthier and useful day-to-day.

On the launch drive program, which took in some urban but mostly rural B-road running, we saw an average consumption figure of 17.1kWh/100km in the Esprit Alpine, which is pretty good in those conditions.

The car’s 400V electrical architecture allows for DC charging at up to 130kW for the entry model and 150kW for the bigger-battery variants.

At that speed, claimed 15-80 per cent charge times are 32 and 37 minutes, respectively. Not the best, not the worst. AC charge capability is 11kW on all models and a Mode 3 charging cable is included.

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.

Renault says the entry-grade Scenic Techno will accelerate from 0-100km/h in 8.6 seconds with the more powerful Techno Long Range and Esprit Alpine lowering that number to 7.9sec. So, it’s quick without being scary fast.

It’s certainly nippy in traffic and at the risk of stating the bleeding obvious, quiet. Even in the context of premium EVs the Scenic is quiet and refined.

Suspension is strut front, multi-link rear and the car feels super planted. The launch drive took in some reasonably rapid twisting corners and there’s no hint of lateral movement in the car. Body roll is minimal, too.

Tyres are energy-efficient Michelin e.Primacy (Techno - 205/55x19 / Esprit Alpine - 235/45x20) and the steering is quick with a relatively low number of turns lock-to-lock. It’s never jerky or too sharp. Rather, it means the car starts to turn into a corner the instant you apply steering lock.

That said, the feel between your hands on the wheel and the front tyres on the road is less than intimate.

There are four drive modes - ‘Comfort, ‘Eco’, ‘Sport’ and ‘Custom’. None of them adjust the suspension tune, it’s more about accelerator response and we found Comfort delivers the best blend of right-foot urgency and overall composure.

Most of the braking you’re going to do will be courtesy of the regenerative system and there are five levels, adjustable via steering wheel paddles, including the most aggressive single-pedal mode.

The one-pedal setting pulls the car up nice and progressively and if you do need to use the physical brakes, they’re ventilated discs all around. Some bite on initial application, but even on downhill corner sections, leaning on them quite hard, they perform well without drama.

Under the heading of miscellaneous observations, you can sense the ADAS (Advanced Driver Assistance Systems) including functions like lane-keeping assist doing their thing occasionally, but it’s all quite subtle, which is a good thing.

The Esprit Alpine’s sports front seats remained grippy and comfortable after a couple of hours behind the wheel. And it’s worth noting the Scenic’s relatively compact 10.9-metre turning circle helps in slow-speed manoeuvring.

Speaking of which, some of the modes in the audio system and external warning sounds for pedestrian safety have been designed by French composer and performer Jean-Michel Jarre, noted for his electronic, ambient-style music. Hats off to Renault for commissioning him.

The Scenic E-Tech has a maximum five-star ANCAP rating from assessment in 2022 with active crash-avoidance tech including AEB (with pedestrian and cyclist detection and junction assist), adaptive cruise control, lane departure warning and lane-keep assist, blind-spot detection, traffic sign recognition, a 360-degree camera view, rear cross-traffic alert, driver fatigue monitoring and tyre pressure monitoring as well as front, side and rear parking sensors.

If a crash is unavoidable, there are seven airbags onboard including a front centre bag and for child seats there three top-tether points across the second row with ISOFIX anchor in the outer positions.

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.

Warranty is five years/100,000km, which is well off the market pace with many competitors at seven, eight and up to 10 years conditional. The battery warranty at eight-year/160,000km matches the market.

Roadside assistance is included for five years, service is recommended every 12 months/30,000km and fixed price servicing is available at a reasonably sharp average of $325 per workshop visit for the first five years.

Renault has 52 dealers across the country covering major cities and key rural areas.
