Mercedes-Benz GLS vs Volkswagen ID.5

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…

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.

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.

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.

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.

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.

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.
 

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.

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.

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.

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 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.

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.

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.
