Renault Scenic E-Tech vs Mercedes-Benz AMG GT

What's the difference?

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.

The GT63 4Matic+ is a breathtaking example of everything that Mercedes-Benz and AMG are.

Ferociously fast, incredibly agile and superbly sophisticated, it should be on anybody’s shortlist, if that also includes a Porsche, Aston Martin, Maserati or even a Lamborghini. And it’s definitely much more than yesterday’s SLC ever was – for similar money in today’s terms, as it turns out.

But, around Tasmania’s glorious roads at least, the Mercedes-AMG lacks the ride comfort and road noise isolation to be a fully-rounded-out GT, and that’s a disappointment for a brand with such formidable history in making such cars.

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.

This is still clearly a Mercedes AMG GT coupe, like the 2014 C190 original, but a ground-up redesign sees it subtly yet significantly altered.

Some 270kg heavier than before, the larger-in-every-dimension body combines aluminium, steel, magnesium and fibre composite materials for improved rigidity and a lower centre of gravity. Length (4729mm) and wheelbase (2700mm) have been stretched by 177mm and 70mm respectively. Width (1984mm) and height (1352mm) are also up.

The nose treatment is similar to before, especially with the bulgy bonnet and signature vertical slatted grille fitted. These, combined with the LED digital headlight shape effect, is reminiscent of, but far-better executed than, the goofy-looking MG5’s face.

Underneath, it's an all-new platform shared with the SL, with the rear transaxle of the old car replaced by a permanent AWD system, leading from 46:54 front/rear weight distribution to 50:50 as a result.

That aggressive, exaggerated cab-backward/ultra-long bonnet silhouette that visually connected it with the SLS gives way to more-conventional and practical coupe proportions that is striking if not especially original, since they do look quite 911-esque. Along with the longer wheelbase and wider tracks, the result allows for two small rear seats to be fitted, while liftback cargo access remains.

Similarly, in the name of way-more usable interior packaging, Mercedes-AMG says it pushed the driving position nearly 180mm forward compared to the previous GT. Let’s see what that all looks like inside.

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 first impression inside is that of space, despite the falling roofline and coupe-like upsweep of the side windows and you look back. While, again, similar to a 911s, a kink at the door gives the GT a unique character.

Even larger people will appreciate the generous amounts of room up front, with space to stretch, sat in sumptuously comfy bucket seats. Note that the standard ones are better than the racier but firmer Sports versions.

The driving position is perfect, ahead of a dashboard that is very typical modern Mercedes in appearance and layout.

To that end, the tablet-style integrated touchscreen (11.9 inches) is clear, fast and intuitive once time is taken to learn it. And points are also won for the multi-configurable electronic instrumentation, that allows for a variety of screens, including track, classic and minimalist views.

The trademark turbine air vents, the quite beautiful material and trim finishes and just the general solid feel are further typical contemporary Mercedes cabin treatments, as are the excellent ventilation and ample storage options.

And while rear vision isn't great, that's what cameras are for. It's all pretty much on brand.

It is a shame, given how elevated the Mercedes-AMG engineering is underneath, that the GT’s interior look and ambience is so similar to those of a (albeit higher-spec) C-Class or GLE. It's simply not as special as some of the company’s previous sports cars.

More annoyingly, the ride is too firm and bumpy for a GT, and this has the unhappy effect of provoking random rattly trim sounds within the cabin. It’s a bit like scrunched-up cellophane. In a $420K (as tested) Merc, that’s very disappointing, especially as it can be heard over the copious amount of road and tyre noise droning through, particularly on coarser bitumen surfaces.

Further back, the rear seat is strictly two-plus-two, and nobody over 150cm tall is recommended to travel there by Mercedes itself. That sloping roofline is the culprit. That said, brief trips with a bowed head are possible, as the fixed cushions and split-folding backrests are actually surprisingly comfy. But only for short journeys. Kids should love it though, and the second row does open up the GT’s usefulness enormously.

As does a near-doubling of the AMG’s cargo capacity, jumping 146 litres to 321L with backrests erect, to a whopping 675L (+325L) in two-seater mode. The flat floor is accessed via a large electrically-operated liftback door, offering quite a large aperture for easy loading/unloading.

Having no spare wheel helps here, with a tyre inflation kit included in lieu of that.

Meanwhile, at the front, under the bonnet, things have definitely changed for the better as well.

Starting from $370,400 (all prices are before on-road costs), the Mercedes-AMG GT63 4Matic+ is priced and positioned as something of an eagle amongst some pretty delectable doves, given its combination of four seats, 430kW of power, 800Nm of torque and four-wheel drive.

No rival equivalents can match the Mercedes on paper. The 398kW/610Nm 911 Carrera 4 GTS T-Hybrid offers less power but starts from $400,000-plus. The 410kW/650Nm GranTurismo Trofeo begins at $450K, the 500kW/800Nm DB12 from $455K and the 404kW/470Nm Continental GT from $460K.

Only the 460kW/750Nm BMW M8 Competition comes closest to the Mercedes-AMG, from $380K.

Side note, today’s GT is only slightly more expensive than what the 450SLC was nearly half a century ago when adjusted for inflation.

And, just like with that classic old Benz, it shares much with the brand’s legendary SL convertible stablemate – including, in this case, standard all-wheel drive and active rear-axle steering… aka 4WS to select third and fourth-generation Honda Prelude owners out there.

What else does $400K-plus buy you? As you’d expect, the GT63 4Matic+ comes choc-full of standard equipment, much of it typical of the luxury coupe breed, with leather-covered and electrically operated everything.

How about a front-axle lift system with GPS-enabled memory that automatically raises the GT’s nose to help clear bumps and then remembers to do so next time?

There are climate-controlled AMG sports seats with inflatable bolstering and massaging functionality, a fixed glass roof, a head-up display, augmented-reality satellite navigation, 360-degree surround views, performance telemetry data as part of an extensive multimedia system, an 11.9-inch portrait touchscreen, 11-speaker Burmester audio, a handsfree-powered tailgate, 21-inch alloys and cutting-edge driver-assist safety tech. More on that in the Safety section below.

Then there are the myriad option packs, bumping the GT63’s price up towards $500,000. These include a $2.7K seat trim package; a $10K AMG Night Package that adds darker trim treatments (often where chrome was); an aerodynamics package with fixed spoiler replacing the standard active spoiler; a $2.6K AMG Performance Seat package; a $13K Carbon Fibre package and $13.2K Ceramic Brakes.

Now, while the new GT does ditch the previous model’s unique rear transaxle spaceframe pioneered by the gull-winged SLS of the early 2010s, the resulting longer wheelbase and shorter overhangs do provide less outlandish and more practical design.

Let’s check that out in more detail. 

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.

There’s a plaque signifying which engineer “handcrafted” the GT’s engine – in this case, the famous M177 in 3982cc, 4.0-litre twin-turbo intercooled V8 petrol guise.

Delivering 430kW of power at 6500rpm and 800Nm of torque from 2500-4500rpm, it sends drive to all four wheels via a nine-speed multi-clutch transmission (dubbed MCT in AMG-speak), catapulting the GT63 4Matic+ from 0-100km/h in just 3.2 seconds, on the way to a top speed of 315km/h.

How does it do that?

With AWD, the GT is now nearly 15 per cent heavier than before, but it still manages a punchy 218kW/tonne. Active aerodynamics over, inside and under a more-rigid body structure also helps.

The AMG 4Matic+ AWD system goes from 50/50 front/rear, to 100 per cent rear, variable torque distribution according to conditions and settings, and backed up by an electronic limited-slip differential. Among the many driving settings are Race Start, Drift Mode and good-old Comfort, if it all becomes too much.

Also keeping all that performance in check is a high-performance composite brake setup with improved cooling for faster responses.

Interlinked active roll bars improve body control, the five-link independent suspension features adaptive dampers for a softer ride.

And, as for that 4WS tech, the rear wheels steer opposite to the fronts at up to 100km/h (by some 2.5 degrees) for tighter and tidier handling, or 0.7 degrees in the same direction above 100, for greater stability and road-holding.

Its effect on the way this near-two-tonne coupe zigs and zags around corners is something you need to experience to really appreciate.

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.

Actually, the GT’s economy isn’t horrendous considering how fast it can go.

Even blasting a few times around beckoning country roads, we managed an indicated 13.0L/100km, which is an improvement on what Mercedes-AMG says the GT averages the 14.6L/100km average that Mercedes-AMG officially states.

That translates to a carbon dioxide emissions rating of 334g/km.

Using 98 RON premium unleaded petrol, an average of just under 480km between refills of the 70L tank is possible. The urban run sees consumption rocket to 21.8L/100km (for just 321km of range), or 10.4 out on the highway run, meaning that over 670km is possible should you decide to drive in a docile manner.

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.

Nobody will drive the GT63 4Matic+ and think, ‘Oh, this is OK’, because its breadth of performance is phenomenal.

No matter which mode you're in, from Comfort through to track-tuned Race, the Mercedes-AMG blends forceful pace and commanding control without ever breaking a sweat.

Flex your right foot and the two-tonne coupe bounds into action like a giant on a mission, striding past posted speed limit signs in nanoseconds and way, way faster than the law will stand if diligence isn’t exercised.

And there’s no point relying on seat-of-your-pants sensations, either, because the chassis below embraces the road with an almost zealous devotion. Which is astounding, given how agile the four-wheel steering-enhanced handling is.

The 63’s super power is exactly that – it dulls your sense of speed. One tester admitted to exceeding 150km/h before noticing. An odd confession considering the sonic boombox that is the bi-turbo V8’s howl.

But jailbait performance is not even the 63’s most lingering joy. That would be its steering perfection, that delivers that rare trifecta of keenness, crispness and communication. The wheel feels eager and alive in your hands, even when powering between tight turns, backed up by sensational grip and control. How can a two-tonne GT handle so sharply?

Warm, dry roads were the order of the day, so we can’t tell you how the 4Matic+ permanent AWD system deals with wet or slippery surfaces, but the slick multi-clutch transmission, seamless torque-vectoring tech and sticky tyres more than cope with the 63’s formidable outputs.

So, that's the gushing part out the way, then.

Despite the adaptive dampers, rigid architecture and exquisitely sophisticated suspension, the ride is simply too stiff in Comfort mode, and downright jittery on some of the Tasmanian roads we tested on, for the 63 to be considered a true luxury grand tourer. It just isn't comfortable, luxurious or supple enough.

Plus, grippy as they are, the 21-inch wheels transmit too much road and tyre noise through to the cabin, meaning that the GT isn't as quiet as you'd hope. Add the aforementioned trim squeaks, and the expected cocooned silence isn’t always there.

The upshot is that the 63 possesses more of a sports car character than a luxury GT character. Great news if you're a 911 type buyer and are seeking a high-performance 2+2 alternative, but a disappointment if comfort and refinement are priorities.

Still, it is impossible not to be deeply moved by this Mercedes-AMG.

While the GT doesn’t score an ANCAP rating – probably because it’s too expensive to crash test – we’d wager that it would be above-average, given Benz’s track record as a pioneer in this field.

That’d due to the scores of active, passive and driver-assist safety features fitted, from multi-faceted autonomous emergency braking (AEB) and lane-support systems to Mercedes’ PRE-SAFE tech that anticipates a crash and then prepares the car for impact.

More specifically, the GT includes Active Lane Change/Keep Assist, adaptive high beam as part of its megapixel LED set-up, adaptive cruise control, Cross-Traffic Assist, Evasive manoeuvre support, an emergency services call-out system, 360-degree camera views, pedestrian protection bonnet and eight airbags.

In other Mercedes products of today, AEB operating parameters are 7-80km/h for vulnerable road users like pedestrians and cyclists, and from 7-250km/h for vehicle-to-vehicle, while the lane-keep support systems operate between 60-200km/h.

Finally, there are ISOFIX child-seat anchorages in the front passenger seat and two in the rear seats.

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.

What’s the GT like to own?

Mercedes-Benz offers a five-year/unlimited km warranty, with five years of roadside assistance. This is average for most mainstream and luxury brands, but superior to most sports-car makers like Porsche and Lamborghini.

Intervals are every 12 months or 20,000km, and while no capped-priced servicing is offered on the GT, pre-paid three-, four- or five-year service plans are available, ranging from $5165, $7700 and $8665 respectively.

Big performance demands big maintenance bills, it seems.
