Citroen C5X vs BMW XM

What's the difference?

This is a new take on the Citroen station wagon, and it’s an impressive one at that. It may not tick all the boxes, but it is a comfortable and practical car, with stunning design, decent equipment and a pretty agreeable price tag.

Now, just get that plug-in hybrid version in at a reasonable price please, Citroen.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

Citroen reckons the C5 X combines SUV, wagon and sedan design cues to make it a true crossover model. I reckon they’ve got a point, and while it’s certainly not as butch as some other crossover wagons out there, it’s not bashful, either.

I’m a massive fan of the assertive front end lighting design, the bold body lines that punctuate the bonnet and swoop backwards down the sides of the car, and the swooping roofline that dips away, almost like the iconic Citroen DS.

It’s quite a large car, too - at 4805mm long on a 2785mm wheelbase, it has a commanding presence, and it’s 1865mm wide (not including the side mirrors) and a rather sleek 1490mm tall. 

Of course it has some body cladding and black plastics to give that ‘rough and tumble’ appearance - and the rear features a couple of spoilers on the boot that help it cut through the air cleanly, and they look interesting as well.

Inside, there’s an almost-square steering wheel, which is interesting, and a pair of screens - a 12.0-inch touchscreen for your multimedia duties, and a 7.0-inch driver info screen. It looks and feels upmarket and pretty conventional in the cabin, so let’s see what the practicality is like.

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.

The Citroen C5 X is almost as big as a Subaru Outback, and similar in size to a Kia Stinger. So it ought to have a bit of family-friendliness packed in.

Starting at the back, there’s a 545-litre boot capacity, with the kick-action, electronically controlled tailgate that you can also use the keyfob to open. It is a low, wide, quite squared-off aperture, meaning loading bulky items in should be a breeze. Just note that the roofline does taper down towards the rear, so bigger things will need to be pushed towards the seat backrests.

Or, if you’re really acting like a delivery van, you can drop the rear seats down to allow 1640 litres of cargo capacity. There are boot-mounted releases to drop the seats down, and there’s a floor mat in the boot, under which is a space saver spare wheel.

Back seat occupants are decently catered for. I’m 182cm/6’0” tall and I managed to sit behind my own driving position with plenty of leg and foot room - however, the sunroof does create a bit of a hump in the ceiling that you might bump your head on, and those with big feet or small children might want to take note that the sills in the door openings are very tall. A child could easily trip over them if they were clambering in the back in a rush.

Children will be covered with a pair of ISOFIX child-seat anchor points in the window seats and three top-tether restraints, too. There are map pockets, door pockets with bottle holders, a pair of USB-C charge points and directional air vents, too.

However, it wouldn’t be a French car without some kind of quirky cup holder situation, and the back seat has none - there’s no flip-down armrest to speak of. But the seat is exceptionally cushy.

Front seat impressions are good - and cup holders are present. They’re big ones, too - large enough for a big cuppa or a bottle of water, even, And there are door pockets with bottle holsters as well.

There’s an opening centre armrest box with a USB-C charge point, and in front of the interestingly designed recessed gear selector and parking brake, there’s another storage spot with a wireless phone charger, too. Nice.

Seat comfort up front is very good, with lots of adjustability (eight-way electric for the driver, six-way electric for front passenger) and heated front seats as well.

Scoring a big tick from me is the fact there are physical dials and buttons for the air conditioning and ventilation controls. But they’re in that glossy black finish, which shows fingerprints so much that it makes you feel self-conscious of being a walking germ farm.

The big touchscreen multimedia system has a few buttons and knobs, too - though the menus on screen do take some getting used to. It is highly customisable, so if you bought one you’d set it and forget it, but on first impression I struggled to get to grips with some of the nuances of the menus.

It does, however, have wireless or wired Apple CarPlay and Android Auto (with the media-feed USB-C port under the controls) and it goes full screen, too, while leaving enough space for other crucial elements. The graphics are nice and high-definition, and the 360-degree camera display puts  the “surround” view units in Peugeot models to shame. 

There’s also a configurable driver info screen, and a crisp and lovely head-up display as well. 

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.

Yes it’s almost 2023, but the Citroen C5 X model launching right now isn’t bringing anything new or exciting to the table in terms of what’s powering it.

Instead, it runs a 1.6-litre turbo-petrol four-cylinder engine that is also used in other Citroen and Peugeot models. No hybrid tech, no electric version yet….  But Citroen has stated it is keen to bring a plug-in hybrid model to the market. Hopefully, it comes soon.

The petrol motor used here is the brand’s PureTech 180 with Stop & Start, and it’s good for 133kW of power at 5500rpm and 250Nm of torque at 1650rpm. This isn’t a small car, but it is relatively light, weighing in at 1439kg (tare mass). 

However, it has a pretty small engine with low outputs for this type of vehicle. For context, the 508 from Peugeot has 165kW and 300Nm.

The C5 X has a standard fit eight-speed automatic transmission, and despite some SUV pretences, it’s a two-wheel drive, with power sent to the ground via the front wheels only.

That much-anticipated plug-in hybrid (or PHEV) uses the same petrol engine but adds an 81kW electric motor to the mix, for a combined output of 168kW of power and 360Nm of torque. Grunty.

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.

If you see a brand-new Citroen C5 X in the showroom or on the street you’ll note that the sticker on the windscreen shows an official combined cycle figure of 6.0 litres per 100 kilometres. For a petrol engine, that’s impressive.

Now, whether you get near that will be determined by how you drive. Lots of city and urban driving could result in a higher figure - but it does have start-stop tech for the true traffic grind.

On the launch drive, which included a mix of different driving situations, I saw an on-display return of 8.5 litres per 100 on the trip computer.

Fuel tank capacity is 52 litres, meaning a driving range of 866km if you can achieve the official figure, or 611km if you average what I did on the launch drive.

Can’t wait for the plug-in hybrid version of this car; it has claimed efficiency one-fifth of the petrol version launching initially - yep, it sips a claimed 1.2L/100km… but of course that relies on you making sure you actually charge it up and use the 50km of EV driving range it is said to offer. We’ll cover it off in more detail when the vehicle launches locally, likely sometime in 2023.

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.

If comfort is your main priority when it comes to your new car, then the Citroen C5 X (or any Citroen, really) should suffice.

The brand says that comfort is one of its defining features - a pillar of why Citroen exists, if you will - and as the flagship model in the brand’s lineup, this should represent the ultimate in comfort. 

And it does. 

The seats - with triple-layer foam - play a big part. They’re wider than most seats and, while they don’t hold you in place like the buckets in a sports car, this isn’t a sports car. 

It also has acoustic glass front and rear to help make it feel more serene and ‘cocoon-like’ inside. There’s barely any wind noise, and just a touch of road roar over coarse-chip roads, but it’s far from noisy in the cabin.

Further, it glides along with relative comfort over bumpy sections of road, with the so-called Suspension with Progressive Hydraulic Cushioning all-but eliminating road surface intrusion into the cabin. 

The suspension has hydraulic cushions at the ends of the springs and dampers (but before the bump stops) that are designed to delete the little bumps in the road surface, while also helping lessen the impact of larger imperfections like potholes. And, with the launch being held in Sydney on yet another wet day, the suspension did a spectacular job. 

You can still feel the 19-inch wheels moving around a bit when you sink into a pockmark, but the way it feels from the driver’s seat is very good. I didn’t get to play passenger on this launch drive, but the seat of the pants vibe I got was that all occupants will be cosseted nicely. 

That tendency towards relaxed movement is reflected in the handling of the car, too. It’s not a corner carver. You can engage Sport mode - which adapts the powertrain (engine and transmission calibration and sensitivity) and also the steering weight, if you really want to.

On the engine - it is perky enough in Sport mode and can do the 0-100km/h sprint in 8.1 seconds, according to Citroen.

This powertrain should really be categorised in the ‘comforting’ rather than ‘compelling’ category. It’s not a bad engine - but you can feel the weight of the car is holding it back, and it particularly feels a bit sluggish from a standing start. I also noticed a bit of vibration through the car under full-throttle acceleration, too. 

But honestly, unless you were trying to duck through a gap in traffic, you’re not likely to spend much time with your foot pinned to the boards in this car. 

I love and admire that this isn’t a car designed to be sporty. It isn’t trying to be that. The PHEV version will be more of a driver’s tool, with an adaptive suspension system and more power and torque. But honestly, I’d be happy with the C5 X as it is, because it’s just a lovely car.

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.

Buy a Citroen and you get a five-year/unlimited-kilometre warranty, as well as five years roadside assist and a five-year capped price servicing plan.

The C5 X isn’t cheap to maintain, with the average service cost sitting at more than $560 - that’s based on service intervals of 12 months/15,000 kilometres. 

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.
