Mercedes-Benz AMG GT vs Volkswagen ID.5

What's the difference?

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.

At long last, the ID.5 GTX arrives to make a different pitch than many of its electric rivals. Less about straight-line speed and more about refinement and handling, this EV mid-sizer makes a case for itself, even if it’s not as good value as its ID.4 sibling.

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.

The key differentiator between the ID.4 and ID.5 is of course the ID.5’s descending coupe roofline. I think it grants the GTX more presence on the road, and I appreciate the touch of having a true three-dimensional spoiler piece atop the boot lid to round it out rather than a more common lip or roof-mounted extension.

Outside of this, the ID.5 sets itself apart from the rest of the Volkswagen range thanks to its curves rather than hard edges as well as contemporary light bar fittings, front and rear.

The overall visage is fresh but a tad conservative, especially compared to the more radical designs we’re seeing on new-to-the-market automakers like XPeng, or those looking to make a splash with their electric offerings, like Kia with its EV5.

There’s certainly something to be said for a more moderate approach, though, as it feels more resolved than many rivals.

Inside, to a degree, the ID.5 follows similar trends in the market, with a minimalist and screen-dominated dashboard.

The 12.9-inch central touchscreen unit is less overbearing than some 15+ inch units in other cars, and this combines with the sensible 5.3-inch digital instrument cluster to make it feel more like a car than a tech product on wheels.

Still, the minimalist theme prevails, with the ID.5’s interior being free of a space-consuming raised console or a smattering of buttons to interact with.

The seats in this GTX are particularly cool, with the single-piece backing like a Golf GTI, red stitching and nice material quality. 

It leaves you with the impression the ID.5 is modern but with the build quality and know-how of a storied automaker, which is a nice balance.

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.

First, the less-good. The minimalist and button-free interior will be a major downside for many. Pretty much everything in the ID.5’s cabin is touch-based. There’s not even a stop/start button, you just sit in the car and it’s ready to go. Additionally, it relies on the now-maligned touch sliders below the multimedia screen for volume and temperature adjustment. Never fun to use on the move. Even the buttons on the steering wheel are the touch-based haptic-feedback kind.

At least the software shapes up. It’s easy enough to navigate, and has a slew of straightforward menus. It’s also backed by enough processing power, with swift responsiveness, and the panel quality is good too, with a sharp, high-resolution finish.

This can be a double-edged sword, though. The high-resolution leads to small shortcut icons across the top of the main screen. While I’m glad the ID.5 has these so you can swap between things like the car’s settings menu and, say, Apple CarPlay easily, it takes some accuracy to jab at while you’re trying to drive.

From there, though, the cabin is clever. Free from the trappings of buttons and a raised console, it feels spacious in every dimension and the seat comfort is excellent with lovely side bolstering and padding.

The seats feel quality, but I wonder whether the synthetic suede-style microfleece trim will age as well or be as easy to clean as cloth or leather. Worth thinking about if you plan to keep this car for a long time.

I even like the touch of having little flip-down armrests which almost makes it feel like you’re being silently propelled along in an armchair in the front seats.

You need these because there’s no traditional raised console with an armrest box. Instead there’s a flexible floating central console piece. It features a modular sort of design, where you can make use of either dividers or a drop-in bottle holder piece in either the upper or lower sections, depending on your preference. Remove these things entirely to have two massive trays.

Meanwhile, the lower section features a cubby with a wireless phone charger, and it also houses the dual USB-C ports with a sliding cover so you can keep the interior tidy. I like it.

There are large bottle holders in the doors, too, and another nice touch is the digital dash being perched on the steering column, so no matter how you adjust it, you can always see it.

The back seat is also excellent in the ID.4 and ID.5, featuring plenty of space for me behind my own driving position, at 182cm tall. There’s heaps of airspace for my knees, and because there’s a flat floor courtesy of this car’s dedicated 'MEB' platform, there’s plenty of space for your feet. It also makes the centre position usable by an adult, which is rare.

Soft trims continue in the doors, but my favourite feature of the ID.5’s rear bench is how the brand has thought to strongly contour the outer two seat backings so even they have plenty of side bolstering.

The backs of the front seats feature an upper pocket for phones and the like, and a larger lower pocket, while the doors feature a large bottle holder each. A drop-down armrest has three shaped cavities for bottles of all sizes, and behind it is a ski port door.

There are adjustable air vents and a touch panel to control the rear climate zone, but because of the low design of the central console, they’re basically on the floor. Nice to have them, but they might be hard to adjust for kids or the less mobile.

This will surprise you. The boot is bigger in the ID.5 than in the ID.4 despite this car’s descending roofline. Measuring 549 litres, it’s also good for the mid-size segment and features an under-floor storage area which is great for your charging equipment. However, there is no spare wheel, just an inflator kit, and also, the ID.5 doesn’t get a frunk like many of its electric contemporaries.

Value is an interesting thing in this case. When you compare the ID.5’s $72,990, before-on-road costs, starting price against its ID.4 Pro sibling (which starts from just $59,990) it doesn’t feel like great value.

This feeling continues when you start to line it up against recently-arrived mid-size electric Chinese offerings, like Leapmotor’s C10 (from $43,888) and Geely’s EX5 (from $40,990). 

But the ID.5 is designed to be a cut above, with a punchy all-wheel drive powertrain, and a relatively large battery, and when you consider its price against, say, the Toyota bZ4X (from $74,900 in AWD form), Subaru Solterra (from $69,990), or high-grade versions of cars a size-bracket down, like the Hyundai Kona Premium (from $68,000) or Kia Niro GT-Line (from $72,360), the ID.5 suddenly starts to look like great value.

If you want my opinion? The ID.4 Pro is still the pick of the two on raw numbers, especially since the difference in standard equipment seems to hardly justify the additional price jump, but I can see how the ID. 5 GTX can make a case for itself.

On the topic of standard equipment, the ID.5 GTX has VW’s signature ‘Matrix’ LED headlights, flush doorhandles, '3D-effect' LED tail-lights, privacy glass, an upgrade to 20-inch alloy wheels and contrasting black highlight trims with GTX highlights on the outside.

On the inside the ID.5 scores a 12.9-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, a 5.3-inch digital instrument cluster, ambient interior lighting, tri-zone climate control, a panoramic glass roof (with powered shade), a premium Harman Kardon audio system and sports front seats trimmed in leather and 'microfleece' fabric, with power adjust, heating, and message functions for the front two positions.

On the performance front it gets the same adaptive chassis control (with frequency responsive dampers, adjustable settings and progressive steering) as the ID.4 Pro, but from there it adds a second motor (on the front axle) and all-wheel drive software with additional drive modes and an 'ESC Sport' setting.

It’s good kit, but whether it’s enough to tempt you away from its closest competitors, like the futuristic Kia EV5 GT-Line (from $71,770), incoming new Tesla Model Y (from $58,900) or unusual XPeng G6 (from $54,800) is a tough question.

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.

Instead of a frunk there’s simply a mess of hardware under the bonnet which is largely related to the ID.5’s high-voltage and cooling systems, but what sets the GTX apart is the addition of a front motor to add to the standard rear one.

It’s not a huge power boost. The ID.4 already puts out 210kW/545Nm, and the front motor on the ID.5 simply adds 40 additional kW for totals of 250kW/545Nm (as the torque figures for the two don’t simply add together).

Its claimed 0-100km/h sprint time of 5.4 seconds isn't bad, especially compared to combustion equivalents, but it’s also not as breakneck fast as some of its EV rivals.

Instead, the additional motor for the ID.5 GTX is more about adding something to the handling equation, as well as the dependability of all-wheel drive and additional drive modes. More on this shortly.

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.

One of the biggest benefits of the Australian market waiting this long for VW’s ID. range is the upgraded battery and charging offering.

The ID.5 GTX has a larger battery than the ID.4, measuring 84kWh which helps off-set its slightly less efficient all-wheel drive system. The result is a WLTP driving range of 522km between charges, which is only 22km less than the ID.4. It’s still plentiful, and on the higher end at this price point.

Additionally, the charging specs are great. A peak speed of 175kW on DC means a charge time of around 22 minutes (10 - 80 per cent) on a pylon capable of outputting such a speed, while on AC it is 11kW, making it worthwhile plugging in down at the local shops.

The big missed opportunity here is the lack of vehicle-to-load, vehicle-to-grid or a household power outlet in the cabin or boot. These are convenient features becoming more prevalent in the market. At least VW throws in a wall socket and a Type 2-to-Type 2 charging cable as standard.

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.

The ID.5 GTX isn’t quite in the same vein as other ‘performance’ EVs. It feels more measured than a Tesla Model Y Performance for example. But then it also feels a lot more organic. It feels a lot more like a car.

This is because rather than focus on straight-line performance, the GTX has benefits when it comes to its handling. Compared to the ID.4, for example, the ID.5 is sharper on its front axle, adding a little additional torque at the front to make it sharper and faster to grab the tarmac.

Its accelerator response may be comparatively steady, but somehow the ID.5’s more traditional stability control tuning allows it to have a bit more leeway when you push it in the corners. It grants it a little extra fun factor, where some rivals are too locked down.

Additionally, VW’s experience in providing a balanced ride and sharp steering tune is on full show. While a lot of electric vehicles in this class feel a little over-electrically assisted or even vague when it comes to the steering, the ID.5 feels connected and accurate.

The adjustable ride settings are also a rare win for an electric mid-sizer. This is because you can adjust the ride to suit the conditions. If you’re on a bumpy suburban road for example, you can keep it nice and soft. But if you’re out carving corners in the countryside, a much firmer setting is available to help limit the amount of floaty rebound this car’s low-set battery weight can have.

It does adjust in a limited band, so there’s still a bit of softness to it, which combines with the predominantly rear-drive characteristics to make for a distinctly different vehicle to a Tiguan, for example.

It’s simply not as athletic as VW’s finely-tuned combustion offerings, but then its more plush open-road feel isn’t necessarily worse. At the very least it maintains all those key refinement characteristics which make Volkswagens generally a cut above to drive.

Another key aspect of the driving experience these days is how much active safety equipment wants to interfere with the experience. Many newer automakers struggle with calibrating for Australian conditions, and yet, like many European automakers, Volkswagen has nailed it with the tuning of these systems in the ID.4 and ID.5.

I wasn’t annoyed by any system, even repeat offenders like lane keep assist or driver attention monitoring in our whole two-day drive, which speaks volumes about the difference between the ID.5 and something like a Leapmotor C10.

The ID.5 comes equipped with the full array of active safety gear as standard, with autobahn-speed auto emergency braking, lane keep assist, blind-spot monitoring, rear auto braking, rear cross-traffic alert and adaptive cruise control.

It is also equipped with seven airbags (including the more recently-introduced front centre airbag) and wears a maximum five-star ANCAP safety rating... for NZ-delivered variants. Australia will surely follow soon, but at the time of writing the ID.5 is not ANCAP rated for this side of the Tasman.

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.

VW hasn’t used this opportunity to increase its standard warranty terms of five years and unlimited kilometres, however, the battery pack is covered by an industry standard eight-year/160,000km deal. 

There are other ownership perks designed to coax people into an electric car, though. Servicing, for example, is only required once every 24 months or 30,000km and when packaged up at the time of purchase, very affordable.

A 10 year or 150,000km plan costs $2890, or just $289 a year, which is excellent for a European car, and is even more affordable than some of its Korean and Chinese rivals with generally longer service intervals.

On top of this, VW stresses the repairability of its battery components, and promises parts supply will continue for 10 years after the discontinuation of the ID.4 and ID.5 range in its current form, with repairability through its network for at least 15 years.
