Jaguar I-Pace vs BMW XM

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.

It’s pretty obvious the XM is designed to impress people with big wallets and an appetite for a techy experience that’s also not without a few green credentials. The ability to motor around as a fully-electric vehicle for up to 80km or so is a big plus and the electric-ballroom interior vibe is hard to ignore, as well.

But from our perspective, the full-fat, twin-turbo V8, while offering startling performance, is perhaps a lost opportunity to follow some of BMW’s competitors into the engine-downsizing space. Then again, when you floor the throttle and 2700kg hurtles forward like a big dog on a short chain, you can see where BMW is coming from.

Perhaps the biggest letdown is the ride quality – or lack of it. While it’s understandable BMW wanted the most dynamic version of the XM it could manage, the end result plays against the vehicle’s otherwise long suit of hyper-luxury. Doubtless, BMW would argue that to soften the chassis would have been to introduce a chink into a no-compromise product. But, perhaps, sometimes a sensible compromise is the way forward.

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.

There’s nothing subtle about the way the XM looks. It probably pulls up just short of brutalist (or maybe not) but even those who find its slabs and angles attractive have to admit that it’s bold.

The now-trademark giant nostrils set the mood and the rest of the exterior suggests some kind of armoured transport for presidents rather than wheels for the school run. Doubtless, this will hardly be seen as a fault by those in the market for such a thing.

The real surprise here is that the XM does not share a bodyshell with any other production BMW. Sure, the V8 petrol engine and wheelbase are common to other BMW and M models, but the sheet metal is the XM’s and the XM’s alone. That in itself, is quite a statement of intent.

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.

Given the vast exterior dimensions and a weighbridge ticket the wrong side of 2700kg, it may come as a surprise to learn that the XM is strictly a five-seater with not even an optional third row.

That said, the uber-SUV Lexus LX in flagship, Ultra Luxury, trim offers just four seats in deference to the VIP clientele it’s pitched at, but also comes complete with reclining rear seats and a passenger’s side footrest which the XM can’t match.

Staying in the rear seat, there’s lots of legroom and plenty of space under the front chairs for feet. A lot of that is down to the wheelbase the XM shares with the BMW X7, and even behind a tall driver, there’s lots of space. In fact, compared with a BMW X5, there’s a full 150mm of extra legroom.

The pew itself flows into the door trims for a lounge effect which looks great with the contrasting light-coloured trim, and the centre arm-rest folds down to reveal a pair of cupholders. Extra storage space can be found in fold-out pockets in the rear of each front seat which also house a small, lidded panel that opens to reveal USB ports and power sockets. Dual-zone climate controls are also part of the rear-seat experience.

The gee-whizz stuff hasn’t been ignored, either, and the prismatic roof lining is nothing if not a talking point. But would a panoramic sunroof have been of more value to many buyers? The ambient lighting is a nice touch, too.

Up front, the view is dominated by the giant, twin curved animated dashboards. They deliver information and lots of it, to the point where it can almost seem a bit overwhelming.

The head-up display helps simplify things, but there’s absolutely no doubt there’s a lot going on in this cabin. Again, this is modern luxury motoring, but it remains that the menu system will take time to learn, even if the touchscreen function gives you an option on how you control things.

Multi-adjustable front seats are part of the deal and there’s an M-spec steering wheel which is heated. And although it features plenty of buttons, isn’t as daunting perhaps as the multi-spoked equivalent in some high-end AMGs of late.

The stereo system is also worthy of a mention, being a Bowers & Wilkins unit with roof mounted speakers and no less than 1500 watts of power. Digital radio is part of the package.

Even though it doesn’t offer a seven-seat option, luggage space in the rear of the XM is hardly class-leading. Cargo volume with rear seat up is 527L and 1820L with it folded.

Much of the wheelbase is devoted to rear-seat stretching room and although the batteries for the electric motor are positioned under the rear seat, the floor of the cargo area seems quite high.

The XM is one of those 'no options' vehicles. That is, you pay the basic price, you get one with the lot. The aged leather and even the optional 23-inch wheels and tyres are no-cost options, so it’s clear where BMW is aiming the thing.

As well as the plug-in driveline, all-wheel drive and all the M driving focus, the XM features plenty of tech including massaging front seats, heated seats all around, a high-end stereo, heated and cooled cupholders, four-zone climate-control, wireless phone charging and twin, curved info screens for the driver measuring 12.3 and 14.9 inches. The novel roof lining also features 100 pin-point LEDs for effect.

The cost of such detailing is a not insubstantial $302,200. That figure does, however, undercut two of its main rivals, the Lamborghini Urus ($395,888) and the Aston Martin DBX ($356,512).

It’s also worth mentioning that the XM is not even BMW Australia’s most expensive model; in fact, it’s fourth on the ladder.

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…

Here’s where the XM starts to justify its price-tag. While the use of an electric motor to boost a petrol engine has allowed some manufacturers to reduce the capacity of the latter, no such restraint has been shown for the XM. Instead, it gets the full 4.4-litre, twice turbocharged V8 that we’ve come to know and love from this brand.

It’s not that this is the engine’s first date with hybrid technology, but the mild hybrids that have come before it can’t match the XM for sheer brutality when both power units are unleashed.

The petrol V8 can muster up 360kW and 650Nm which, when boosted by the electric motor, jumps to a total of 480kW (combined) and 800Nm.

While the petrol engine drives through an eight-speed torque-converter automatic, the electric motor also drives through the transmission, an arrangement that is a bit different to some hybrids which use the petrol engine for the rear axle and the electric motor to drive the front wheels.

Of course, the requirement for the XM to feature permanent all-wheel drive, regardless of what power unit is running at the time, forces this layout.

Speaking of all-wheel drive, The XM’s version of BMW’s 'xDrive' layout has been specifically tuned for this vehicle and includes torque vectoring as well as a limited-slip rear differential.

The system has the ability to vary the torque split front to rear, with the default rear-bias giving a more sporting feel on good surfaces. An active rear differential also helps give the car a rear-drive feel.

As well as modes for 'Hybrid', 'Electric' and 'eControl' modes, the XM sticks with the M tradition of offering two M buttons which can be configured to set the parameters for steering, driveline, chassis and, in the case of the hybrid XM, the degree of braking regeneration offered.

Four-wheel steering is also part of the XM’s repertoire and, interestingly, there’s no air suspension here; just conventional steel springs.

But it does feature an electrically-adjusted anti-roll bar system which aims to strike a happy medium between what the driver wants and the road conditions demand.

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.

A 25.7kWh lithium-ion battery provides the power for the electric drive. It’s mounted under the rear seat and can produce a purely electric range of between 82 and 88km (based on WLPT test protocols).

Charge time from a conventional wall-box is said to be about four hours but, interestingly, the XM has no provision for DC fast-charging.

Fuel consumption (combined cycle) is an EV-typical 2.7 litres per 100km, which equates to a low 61g/km of CO2.

Once you’ve depleted the battery on a highway journey, expect the petrol V8 to consumer somewhere between eight and nine litres per 100km at cruising speed.

Using EV mode means zero-emission operation but, as with any electric car, how the power is generated to recharge it determines its real-world green-ness.

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.

While any M car is supposed to be rapid and dynamic, it’s also true that the over-arching perception of big SUVs is that they’re comfortable and plush. None of which explains the ride in the XM.

Regardless of how you fiddle with the settings, the ride is always brittle. Those big tyres with their minimal sidewall somehow manage to find every crack and join in the road, and it’s these sharp-edged imperfections that thump through to the cabin the most vocally.

It’s enough to make you wonder who this car is going to appeal to. Will it take to race tracks? Almost certainly not. So the whole point of these suspension settings might be a bit lost on some people.

Performance, meanwhile, is insanely rapid for something that could pass as a bulk carrier. The biggest giveaway to the mass is the transmission’s earnest attempts to keep everything moving by feeling a bit hyperactive on downshifts.

Using the ratios is always going to be the strategy, but with all that torque, maybe it’d be nice sometimes for the trans to hang on to a taller gear and let the boost blow it towards the next corner.

The sound track? Polarising. Even if it doesn’t convince you that Hans Zimmer (who developed the various electronically-synthesised noises the XM makes) should stick to winning Oscars, the augmented sounds are background noise rather than the main event here.

Even the petrol V8’s naturally stirring backing vocals have been electronically tweaked with debatable results.

That said, it’s nice to have something to listen to that isn’t the insistent tyre roar which becomes even louder on coarse-chip surfaces.

Steering effort is light but there’s not a lot of feedback in terms of actual feel. In fact, it’s borderline detached and only the sheer speed of the rack confers any athleticism.

Also, the rear steering seems to come in a few milli-seconds after the front has started to turn. And for all that all-wheel-steering agility, this is never a car that shrinks around you.

As well as the usual passive safety features, the XM also hides the latest active safety gear. In fact, BMW reckons the XM has more driver assistance than any other M car before it.

Those elements start with the 'Driver Assistant Professional' which bundles active cruise-control with stop-go ability, steering and lane-keeping control, automatic speed limit assist and active navigation.

Parking assistance is also featured which incorporates a reversing assistance function, front, rear and panoramic camera views with a 3D view built in.

BMW’s 'ConnectedDrive' includes an emergency call function in the event of a crash or other emergency.

No ANCAP assessment so far.

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.

Like a lot of manufacturers, BMW knows consumers can be leery of EV tech when it comes to the cost of battery replacement. So, as well as the five-year/unlimited-kilometre warranty on the whole vehicle, there’s also eight years or 160,000km of cover for the high-voltage battery.

Servicing intervals are based on how the car has been used and it will inform the owner when a service is required.

A servicing package is included in the purchase price and BMW even throws in three years of roadside assistance.
