Citroen C3 vs BMW XM

What's the difference?

The Citroen C3’s plus column contains some big ticket items like a solid standard equipment list, design flair, generous interior space, an eager engine, good safety and a comfy suspension. However, the minus side of the ledger isn’t exactly empty, with entries like steep price, marginal perceived quality, poor cabin storage, sub-par refinement, okay economy, and high ownership costs. 

But there’s no doubt this car delivers a different, adventurous take on the city-sized hatch, and for you, that alone may count for more than any of those things. 

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.

If Citroen is known for anything it’s daring, innovative design. From the idiosyncratic 2CV, via the sleek DS, to the ultra-cool SM, and angular BX, Citroen boasts a 100-plus year back-catalogue of stunning automotive breakthroughs.

And true to form, the C3 sits left-of-centre with a determined, almost angry expression defined by chrome borders extending from its signature ‘double chevron’ logo above the grille.

A mix of carefully radiused curves, soft organic shapes and whimsical decoration define the rest of this SUV-ish hatch. Rounded rectangles and squares (squircles?) are a recurring theme, forming part of a dent-resistant panel along the car’s flanks and embossed into the door cards inside.

Our white test example sported a (no-cost) contrast red roof colour, the same shade picking out details like the front fog light surrounds, exterior mirror caps and side scuff panels. 

The interior is less bold with a multi-tone grey colour palette broken up by light green contrast stitching on the seats, as well as piano black finish on the centre console and satin chrome highlights around the air vents, instrument panel and door handles.

Plus, the squircle still makes its presence felt in everything from the directional air vents to the speaker grilles and sections of the dash.

Functionality and ergonomics are good with sensible touches like a physical knob for audio volume control (big tick) as well as easy-to-navigate controls for audio, phone and more on the steering wheel.

An unexpected highlight, and regular talking point with people in the car during my week with it, is what Citroen calls ‘Luggage-inspired’ front interior door handles. 

Check out the interior photos. The straps look amazing, are easy to use, and remind me of the handle on my mum’s circa-1965 Olympia portable typewriter.  

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.

At a fraction under 4.0m long, just over 1.8m wide, and close to 1.5m tall, the C3 is a small hatch that, in terms of practicality, does well in some areas and could do better in others.

On the plus side, there’s plenty of space for the driver and front seat passenger, and rear room is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I had more than adequate head, leg and knee room.

Three full-size adults across the rear is a short-journey proposition only, but a trio of up to mid-teenage kids will be fine.

The space-efficiency carries over to the boot, with 300 litres of volume available (below the parcel shelf) with the 60/40 split-folding rear seat upright. But beyond that number, the space has been carefully sculpted to maximise usability.

We managed to fit our three-piece (36L, 95L, 124L) luggage set in there, with a small cheat of removing the divider, and could swap them out for the bulky CarsGuide pram, with room to spare. Fold the rear backrest down and available space increases to an impressive 922 litres.

The downside is storage and concessions to comfort elsewhere in the car. As in, a lack of them.

For a start, the dual cupholders in the front centre console confirm the French’s affection for Espresso. You’ll struggle to locate an average size take-away coffee cup in one of those dainty receptacles.

The front door bins are long but relatively narrow, and lack a designated spot to hold bottles upright, so I found myself laying drink bottles horizontally along them, which is awkward.

Plus, there’s no lidded storage box between the front seats, so no centre armrest, either. Rather an open tray behind the handbrake lever.

The glove box is modest, there’s a small open cubby below the central multimedia screen that isn’t big enough to hold a phone, there’s just one USB-A port for connectivity/power and a single 12V outlet.

No fold-down centre armrest in the rear, either. There are map pockets on the front seat backs, a single (again, small) cupholder at the end of the front centre console for back-seaters to share, and while rear door pockets are welcome, they’re petite.

Yes, the boot is commodious, but it lacks tie-down anchors to secure loose loads, and the flimsy carpet in there is prone to moving around.

On a more positive note, the spare is a 15-inch space-saver, which is streets ahead of the all-too common inflator/repair kit.

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.

The Citroen C3 is powered by a small-capacity (1.2-litre), turbo-petrol, three-cylinder engine, driving the front wheels through a six-speed automatic transmission. 

This little unit punches well above its weight thanks to tech like direct injection, and dual variable valve timing to enhance pulling power. The lightweight (all-alloy) unit produces 81kW of power at 5500rpm and a substantial 205Nm of torque at just 1500rpm.

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.

Citroen’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.2L/100km, the 1.2-litre three-cylinder emitting a modest 118g/km of CO2 in the process.

Our time with the car included mainly city and suburban trips, with some freeway running thrown in, and the result was a (dash-indicated) average of 8.0L/100km. Not exactly miserly, and points to the turbo triple having to work pretty hard to keep up around town.

Minimum fuel recommendation is the relatively pricey 95 RON premium unleaded, but you’ll need just 45 litres of it to fill the tank. Using the official consumption figure, that translates to a range of 865km, dropping to around 560km using our real-world number.

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.

The C3’s compact footprint and relatively light weight (1090kg) make it an urban-friendly option and outputs from the 1.2-litre turbo-petrol engine are exceptional.

Maximum torque of 205 Nm is plenty of pulling power from such a tiny unit, and with that number arriving at just 1500rpm it should be ideally suited to stop-start traffic. 

And yes, with enthusiast use of the right pedal the C3 gets up and goes pretty well, but refinement isn’t its strongest suit. 

The throttle can be jumpy unless you’re super smooth with it, the three-cylinder engine’s typically coarse note makes its presence felt under load, and the brakes need to be dealt with gently to avoid an overly aggressive stop.

Sure, familiarity and practice will help you get in tune with the car but it’s not a smooth ‘plug-and-play’ drive like the majority of its competitors.

That said, in true Citroen fashion, steering feel is good, the front seats are as comfortable as they are supportive, while the suspension manages to blend plush compliance with excellent dynamic response. Another Citroen hallmark.

The six-speed auto shifts smoothly, with a press of the Sport button encouraging it to shift up later and down earlier for a more urgent response. But the zig-zag (my term, not Citroen’s) shift pattern makes for an awkward shuffle between D, N and R when parking. No doubt you’d get used to it, but I’m not a fan.

Speaking of parking, the C3's diminutive size makes it easy to slot into even tight spots, the standard front and rear proximity sensors, as well as a decent resolution reversing camera helping out, too.

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.

Citroen covers the C3 with a five year/unlimited km warranty, which is cost-of-entry now in the mainstream market, and roadside assistance is included for the duration.

Service is scheduled for 12 month/15,000km intervals, with costs capped for the first five workshop visits. The average annual figure over that period is $505, which is way more than double the $205 you’ll pay annually for servicing a Toyota Yaris ZR Hybrid. Sacre bleu!

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.
