Jaguar I-Pace vs Mercedes-Benz Gls450

What's the difference?

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.

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

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.

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

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.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

Our Polar White test vehicle, which is the base grade in the three-tiered GLS range, comes standard with a 3.0-litre inline six-cylinder turbocharged diesel engine with 48V mild hybrid technology, nine-speed automatic transmission, permanent all-wheel drive and active air suspension for a list price of $189,100.

This pricing is higher than comparative entry-level grades offered by the two marques which dominate sales leadership in this segment, comprising the BMW X7 xDrive40d M Sport ($179,500) and Lexus LX500d AWD ($158,700).

The GLS450d’s standard features include 22-inch AMG alloy wheels with Continental 325/40 R22 tyres and a collapsible spare, ‘AMG Line’ body styling enhancements, aluminium-look illuminated side-steps with non-slip rubber studs, multi-beam LED headlights and more.

Step inside the keyless interior and you’ll find ‘Hey Mercedes’ voice activation, fingerprint scanner (which memorises individual comfort settings for up to seven users), panoramic sunroof, heat-insulating dark-tinted rear privacy glass and the ‘Premium Plus Package’ that includes heating/cooling for the front seats, heated rear seats, head-up display, separate front/rear climate control zones, heated cupholders and more.

There’s also a concert hall-like Burmester surround sound system controlled by a central touchscreen with digital radio and Apple CarPlay and Android Auto connectivity, plus wireless phone charging, multifunction Nappa leather sports steering wheel and USB ports front and rear.

Driver assistance includes the ‘Parking Package’ (360-degree camera, active parking assist and transparent bonnet), ‘Mirror Package’ (auto-dipping rear-view mirror and electric folding door mirrors with puddle lamp projection of the brand logo) and ‘Driver Assistance Package’ (blind-spot assist, exit warning, speed sign recognition, lane keeping etc) all included as standard equipment.

Of course, Mercedes-Benz offers numerous extra-cost options including a 3500kg towing package plus interior, exterior, suspension and wheel enhancements (including Nappa leather trim) for those who want their GLS with the lot, which can easily push the list price beyond $200K.

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 GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

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.

Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

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.

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

The GLS does not have an ANCAP rating as it’s yet to be tested, but comes standard with a suite of passive and active safety features including nine airbags, auto emergency braking (AEB) with pedestrian detection and junction assist, blind-spot monitoring, traffic sign recognition, head-up display, rear cross-traffic alert, lane-keeping, adaptive cruise control with ‘distance assist’ (autonomously brakes/accelerates in heavy traffic), front/rear parking sensors, 360-degree camera and more.

There’s also two ISOFIX and three top-tether child seat anchorages in the second row, plus two more of each in the third.

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.

The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.
