Mercedes-Benz GLS-Class vs Jaguar I-Pace

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…

In the 1960s Jaguar used to promote its range as providing “grace, space and pace”. Nowadays, the I-Pace may as well also be known as the I-Grace and I-Space, because all three terms still ring true.

Jaguars were never cheap but the greatest hits felt like exceptional value because they were special. The same applies here. Five years might seem like an eternity, but age has not yet wearied the British luxury EV SUV nearly as much as you might imagine. Especially when optioned up as per our test vehicle.

Bereft of any post-modern brand baggage, the I-Pace remains a modern great. If only more buyers would catch on to that.

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.

Five years on, from the bold cab-forward silhouette to the high-riding crossover proportions, the I-Pace is a distinctive and handsome machine, offering progressive, flowing aerodynamics that have as much to do with function as they do with form. This is an out and proud EV.

But there’s the rub. Perhaps the disappointing sales reception is down to it being too removed from what many consumers might expect a Jaguar to look like.

Grille-aside, there isn’t enough connection with stablemates like the woefully-underrated XE or F-Pace, while traditionalists – many of them Americans ­– wanting classic XJ or XK retro schtick are also plum out of luck. Cover the badge and the styling could be from any (forward-thinking) carmaker.  

Or maybe it’s because the I-Pace, whose body is 94 per cent aluminium to help offset the weight of the batteries, looks compact in photos, like a crossover hatchback, when in reality it is surprisingly large, belying its sleek styling by packing in plenty of space inside.

Speaking of which, let’s take a closer look.

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.

Yes, compared to the vast mega screens invading most new models of today, the I-Pace’s dashboard layout is looking, well, off the pace. On first glance at least, this is definitely a product of the previous decade.

But as far as design elegance and functionality are concerned, Jaguar seems to have created a timeless piece of crafted automotive interior architecture that – consequently – holds up very well.

Or, in other words, the I-Pace provides a welcome sanctuary away from the infuriating folly of today’s faddish, fiddly and infuriatingly distracting touchscreen interiors. Maybe some old-school XJ smarts live on in this EV after all.

Look past the dated dashboard design, and the cabin’s overriding impression is of solidity and quality. No cheap plastics or rough surfaces here, just restrained luxury.

While electronic displays with very-analogue-style dial options amid digital driving data take care of the instrumentation ahead of the driver, a modestly-sized touchscreen is set at a lower plain so as to not dazzle and distract the job of vehicle controlling with data-overload, while under that is smaller display for climate control. More on that later.

Part of the Pivo Pro multimedia system, that central touchscreen is switched on and ready for use before the ignition button is even pressed, for immediate action.

No delaying-tactic welcome fanfare as the system boots up as per almost every other carmaker’s set-up, either. Just instant gratification, ironically. This dash is starting to feel like a resto-mod, with all the latest tech behind that Boris-era façade. 

Plus, besides being fast, it is logically laid out and avoids confusing sub-menus. Nice swipey action, too. Some familiarisation is required at first, but the system makes sense. And if you need volume adjustability, you turn a physical knob. As the ergonomics lords intended. Easy.

Speaking of which, let’s get the sensible stuff out the way. Because it sits at near-SUV height, the I-Pace is easy to get in and out of as long as you’re aware of the swooping roofline out back. And you sit up high, affording excellent forward vision ahead.

Sinking yourself into the front seats, the Jaguar lives up to its old luxo-barge reputation in that they’re sumptuous yet firm in back-location and support, providing hours of comfort if required.

The driving position is superb, with ample adjustment and those thoughtfully-placed switchgear and controls coming into play.

Storage is ample, with deep door pockets, a sizeable centre console bin and even a secret cubby underneath the rear seat.

The Jaguar provides five USB outlets and two 12V sockets. And ventilation is as effective as you need it to be.

Problems? Pleasingly, our Graz-built Jaguar suffered from no breakages or squeaks. It is as well-screwed together as you’d expect from a luxury SUV, so there are no issues there to moan about.

However, rear vision is poor due to the tapering rear windows and shallow tailgate glass. In turn, the back-seat area can seem a bit dark and hemmed-in without the (optional) fixed glass roof.

The glove box is disappointingly shallow. And, though simple in execution, the climate control can be fiddly to figure out at first.

Of greater concern is the counter-intuitive transmission selection, since the ‘DNRP’ buttons are placed in descending order, putting ‘Drive’ up top and ‘Park’ down at the bottom.

On several occasions, ‘D’ was selected instead of ‘P’ or ‘R’, nearly leading to unintended forward acceleration into parked cars or walls directly ahead.

As mentioned earlier, our test HSE features the optional suede dash and pillar covers; along with the beautiful woven grey flannel-like trim on Alcantara-like seats, they add a distinctive classy ambience – and that’s something that translates out back, too.

While you wouldn’t call it a large wagon, it is more than sufficiently spacious for two adults, while middle-seat space is A-OK for smaller folk only as the ceiling tapers a bit too much for taller passengers. Legroom is exceptional, thanks in part to a stretchy near-3.0-metre wheelbase.

The bench seat itself does not slide or recline, but the 40/20/40-split backrest seems sufficiently angled for comfort and support, while the cushion is sprung enough not to lead to achy thighs, even for longer-legged occupants.

Amenities include rear-facing air vents, a centre armrest with two cupholders, two USB and a single 12V port, overhead grab-handles and reading lights, (quite shallow) door pockets, four coat hooks and some under-seat storage.

Further back, the Jaguar’s boot area is set up high, so requires some lifting to get heavier objects in, but the floor is long and flat, and the overall volume is quite practical. Capacity varies from 656 litres to 1453L with the backrests dropped. You can fit a 1797mm by 1244mm object in two-seater only mode.

There’s storage underneath for charging cables, as well as straps and hooks to secure loose items. And, as mentioned earlier, buyers can order a space-saver spare if the tyre-repair kit is undesirable. Note, too, that a sizeable ‘frunk’ front trunk is good for a couple of soft overnight bags.

Overall, then, equipped as our $180K HSE was, the I-Pace’s interior is likely to impress.

Unveiled for the 2021 model year elsewhere but finally released just this year in Australia, the updated I-Pace EV400 (denoting the maximum power output in braked horsepower) brings minor visual changes, but more important ones underneath, too.

Most noteworthy are a larger onboard charger (from 7.0kW to 11kW) to substantially increase charging times, an advanced new-from-the-ground-up multimedia system, improved climate control, better surround-view camera options including integration with the rear-view mirror (dubbed 'ClearSight') and wireless charging updates.

They help smother some of the Austrian-built Jaguar EV’s wrinkles against a growing army of fresher alternatives, including the EV6, Audi e-tron (soon to gain the Q8 prefix), BMW iX, Lexus RZ and Mercedes-Benz EQC.

Kicking off from $148,800 (all prices are before on-road costs), the ‘24MY’ (2024 model year) EV400 SE is the latest I-Pace’s opening gambit, though we’re testing the HSE flagship version from $165,600.

Both grades feature an electric motor on each axle for all-wheel drive, a 90kWh battery pack and Jaguar's R-Dynamic pack.

Standard features include LED automatic headlights, electric/heated door mirrors, flush exterior door handles, an acoustic and heat-deflecting windscreen, rain-sensing wipers, keyless entry/start, a rear-view camera, part-leather upholstery, front sports seats with electric adjustment and driver’s side memory plus adaptive cruise control with lane-assist.

There's also dual-zone climate control with remote cabin pre-conditioning, configurable ambient cabin lighting, electronic instrumentation, Bluetooth connectivity, Apple CarPlay/Android Auto compatibility, digital radio, wireless charging, over-the-air updates for the 'Pivo Pro' multimedia system, voice control, a public charging cable, perimeter alarm and three-year subscription to Secure Tracker car finder, a powered tailgate, a bicycle-carrier preparation kit, 20-inch alloy wheels and a tyre-repair kit.

There is no spare wheel fitted but a space-saver is available at extra cost.

Stumping up another $16,800 for the HSE nets you upgrades like leather trim, heated/cooled front seats, heated rear seats, suede headlining, fixed panoramic roof, animated indicators, approach lights in the exterior mirrors, a head-up display (HUD) and different wheels. 

On the safety front, both grades feature six airbags and a decent level of driver-assist technologies including autonomous emergency braking (AEB) as expected at this price point. More on those in the Safety section below.

Now, the I-Pace EV400 HSE R-Dynamic we tested was a 23MY model, which differs from the above in that it started from over $5000 less at $160,217, but isn’t as well equipped as the 24MY.

It also included a number of options that bumped the price up to a tad under $180,000, starting with the $5008 'Premium Black Pack', ushering in air suspension, a rear spoiler, black exterior trim highlights and 22-inch glossy black alloys.

Other goodies included a fixed panoramic roof ($3580), adaptive dampers ($2405), four-zone climate control ($1820), carbon-fibre trim finish ($1521), that ClearSight rear-view mirror ($1131), full-colour HUD ($1040), Privacy Glass ($845) and no-cost 'premium textile' (non-animal derived) upholstery.

The point is, to specify your I-Pace to what you see in our images, you’ll need to add nearly $20K to an already hefty starting price.

This is par-for-the-course for most premium brands, though paying extra for cupholders, a HUD and rear-seat climate control when some carmakers include them seems mean at these prices.

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.
 

Built around a standalone architecture with no internal combustion engine versions, the I-Pace EV400 is fitted with two permanent magnet synchronous electric motors – one above the front axle and one located on the rear axle. Each produces 150kW of power and 348Nm of torque, for a system output total of 294kW and 696Nm.

Tipping the scales at 2226kg, this means the EV400 has a power-to-weight ratio of a very healthy 132kW/tonne, helping this electric crossover cross the 100km/h marker in 4.8 seconds, on the way to a top speed of 200km/h.

With a single-speed transmission sending torque to a motor on each axle, the I-Pace has permanent all-wheel drive.

The I-Pace’s standard suspension is double wishbones and coils up front and an integral link independent set-up out back.

Nowadays, the standard wheel size in the SE is 245/50R20, though ours was fitted with 255/40R22 – along with air suspension and adaptive dampers. These profoundly alter ride comfort. Towing capacity is 750kg braked or unbraked.

Ground clearance is usually 174mm, but with the air suspension, that increases to a handy 241mm in its maximum height setting. At speeds over 105km/h I-Paces with air suspension drop a further 10mm to aid efficiency. Which brings us to…

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.

With a 400V architecture, the I-Pace EV400 has the charging capability of most EVs, but not the Hyundai Ioniq 5 and 6, Kia EV5, EV6 and EV9, Genesis GV60 and Porsche Taycan/Audi e-tron GT fraternal twins, which have an 800V capability.

Under the floor is a 90kWh lithium-ion battery, with a useable capacity of 84.7kWh.

For AC charging, it uses a Type2 connector with 11kW capacity, or for DC fast charging, it has a maximum 104kW capacity via a CCS port. Both are located in the left-hand-side mudguard.

Jaguar says the official combined average consumption is 23kWh/100km. Our car’s trip computer showed we averaged 24.2kWh/100km.

The WLTP range is 408km, or 446km under the more-lenient NEDC regime. Fully charged, our vehicle indicated 407km of range in normal mode and 415km in 'Eco' mode.

After 345km, our distance-to-empty read 14km, meaning we averaged a very reasonable 359km under absolutely normal urban conditions, with some freeway driving thrown in.

Using a 150kW DC fast charger, we added 200km of range in exactly 30 minutes. It cost us around $31.

For the record, AC charging from empty to full using a regular household socket will take nearly 44 hours, or 13.5hr and just 9.25hr if you have access to a 7kW or 11kW Wallbox, respectively.

Meanwhile, a 50kW DC fast charger needs 75 minutes to go from 10-80 per cent full, or 45 minutes with anything above a 105kW charger, as that’s the Jaguar’s maximum capacity.

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.

One of the great EV questions is just how premium brands like Jaguar, BMW and Mercedes-Benz can justify their higher prices, when comparatively inexpensive alternatives from BYD, Hyundai and Kia rely on similar electric motor tech.

Indeed, a Tesla Model Y Performance offers the same acceleration and a higher top speed at nearly $100K under our EV400 HSE as tested.

But then you snuggle into that opulent cabin, buckle up, and realise that – just as the original XJ changed big luxury sedans forever back in ’68 with its sophistication and lush ride – the I-Pace still sets the tone for luxury EV SUVs.

Push the D button and – even in 'Comfort' mode – the Jaguar steps off the line briskly. A long-travel accelerator pedal tune disguises the fact that the EV400 is actually sensationally fast, as it swiftly yet silently streaks towards triple digits in no time at all, accompanied by a dull turbine-like drone.

Select 'Dynamic' mode, and the I-Pace’s performance lives up to both the make and model names, offering instant, pinned-back-in-your-seat thrust as well as ample muscle as it glides along.

Flex your right foot and you're already tailgating Mercedes AMG and BMW M-Sport SUVs in no time. Immediate, addictive speed.

A low centre of gravity; that double wishbone and multi-link suspension layout; near 50/50 weight distribution – we’re expecting something special here, and happily, the I-Pace as optioned up with air suspension, adaptive dampers and 22-inch wheels refuses to disappoint.

The sheer urgency from the twin electric motors is matched by reassuring grip and control, even over the rain-soaked hills we belted along.

Beautifully weighted steering, offering lots of road connection, adds to the sense of confidence and calm, as the Jaguar handles corners with a flat, contained composure.

It’s only when you’re really fanging it through tight and twisty turns that this EV SUV starts to feel its considerable mass.

Keep in mind that our HSE included the optional air suspension and adaptive dampers, because together they provide impressive suppleness and sweet isolation (in Comfort mode, obviously) to go with the I-Pace’s unassuming agility.

They allow for those oversized alloys to swell out the arches without resulting in a ruinous ride – something you’d get a taste of if you switch to Dynamic mode, where everything stiffens up noticeably.

Thus specified, we’d imagine the softness would be well off the scale on the standard 20-inch rubber.  

As tested, our HSE is one of the most enjoyable luxury SUVs to drive and travel in at speed, regardless of what sort of fuel you’re using.

Downsides? Around town, the limited side and rear vision mixed with the Jaguar’s two-metre width makes manoeuvring a little daunting at times.

The turning circle is on the larger side. And the traffic sign recognition tech is far from reliable and doesn’t work in concert with the adaptive cruise control so can’t automatically alter speed to what’s signposted.

Yet our biggest gripe is the lack of greater single-pedal braking when lifting off the throttle.

A set of paddles to alter the regeneration braking force as per Hyundai’s set-up would be appreciated.

This is one of the single biggest giveaways to the Jaguar’s advancing years.

Still, as a hushed, refined, comfortable and forcefully quick luxury EV SUV experience, the I-Pace, with the choice options as fitted, remains a fierce opponent against newer alternatives. Especially from behind the wheel.

Tested in 2018, the I-Pace scored a maximum five-star ANCAP crash-test rating.

It managed to do well in all four of the independent body's disciplines, especially so for occupant protection at 91 and 81 per cent for adults and children, respectively, while vulnerable road users (cyclists and pedestrians) fared worst with a still-adequate 73 per cent rating.

Six airbags are fitted (dual front, head/side front and head/side rear outboard occupants), along with a raft of driver-assist systems, including AEB, lane-alert, lane-assist, blind-spot monitoring, rear-collision monitor, rear-traffic monitor, adaptive cruise control with steering assist, driver fatigue monitor, tyre pressure monitors, emergency call out and traffic sign recognition with adaptive speed limiter tech.  

Note the AEB operates from 5.0km/h to 85km/h, and functions in day and night conditions in all cases including cyclists and pedestrians. The lane support systems operate from 50km/h to 180km/h.

Additionally, you’ll find anti-lock brakes with electronic brake-force distribution and brake-assist, as well as stability and traction controls.

Two outboard rear-seat ISOFIX latches are fitted, along with a trio of top-tether anchorage points for child seats.

No front occupant knee or centre-front airbags are fitted.

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.

The I-Pace is covered by an industry-average five-year/unlimited kilometre warranty, along with five years of roadside assistance.

Additionally, owners will enjoy five years/130,000km of free scheduled servicing. These are at 12 months or 26,000km.

Jaguar says the EV traction battery is covered by an eight-year/160,000km warranty, with a minimum of 70 per cent state of health.
