BMW M4 vs Citroen C3

What's the difference?

Brutal, bruising and utterly brilliant, the M4 CS will be an acquired taste due to its no-compromise approach, but those willing to take the leap will find a performance car like few others at their disposal.

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. 

The M4 CS is familiar in all the right ways, but definitely looks significantly jacked up compared to its lesser siblings.

Part of that is the extensive use of carbon everywhere, from its bonnet panels to its roof, front lip, side skirting and boot spoiler. But also because of its super-muscular angles and creases, including the huge dome in its bonnet.

Also exclusive to this M4 CS is the light treatment, with the front LEDs lighting up with yellow highlights the brand says are supposed to be reminiscent of GT racing cars.

At the back, the rear lights are flush with fibre optic lighting, lending a flowing and unique light signature that looks epic at night.

Inside, it's a sea of carbon, with the lightweight racing seats, the dash inserts and the centre console all lined in it. It is a perfectly finished space, though, and one that's also flecked with red, including a 12 o'clock band on the thick-rimmed steering wheel, the seat backs, the contrast stitching and the paddle shifts.

Be warned, though, it takes some acrobatics to climb into or out of the CS. The seat bottoms have these super high edges that double as grab handles, but require some awkward contortions to navigate.

In short, it looks angry, this M4 CS, inside and out.

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.  

It all boils down to how you classify practicality in a car like this. I mean, the basic stuff is all there – it's got two doors, four seats and a boot capacity of 440 litres.

It measures 4801mm in length, 1918mm in width and 1399mm in height, and room for front seat riders is good, but less so for anyone you squeeze into the back. There are even ISOFIX points for a child seat.

But if you consider practicality the practical pursuit of performance, then the M4 CS has plenty of perks.

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.

The Citroen C3 is offered in a single Shine grade, and lines up against a slew of similarly city-sized hatches from China, Europe, Japan and South Korea. Think Kia Rio, Mazda2, MG3, Suzuki Swift, Toyota Yaris, and VW Polo. 

But when it comes to its price - $32,267, before on-road costs - you’re looking at primo competitors only, like the Suzuki Swift Sport Turbo ($30,990), Toyota Yaris ZR Hybrid ($32,200), and VW Polo Style ($31,250).

And to tempt you away from those more mainstream options, Citroen loads up the C3 with a solid list of standard equipment.

Aside from the safety tech covered later in the review, this small hatch features keyless entry and start, cruise control, a 10-inch colour multimedia touchscreen (with voice recognition across multiple functions), climate control air, a leather-trimmed steering wheel, six-speaker audio (with digital radio as well as Bluetooth, Apple CarPlay and Android Auto connectivity), built-in sat nav, LED headlights and daytime running lights, rain-sensing wipers, and 16-inch alloy wheels. 

Not too shabby, but bear in mind, as is often the case in this class, the trim is cloth, the front seats adjust manually and the instruments are conventional analogue. 

At this point, it’s important to mention ‘perceived quality’, a term used in various industries to describe the look, touch and feel of a product. And it’s here that the C3 suffers. 

Open the tailgate, look to the pillar on the right-hand side of the rear windscreen (from the inside) and you’re confronted with more than half a dozen spot weld craters that have creased the sheet metal to varying degrees. Not to mention a crude fold of the outside panel onto this interior piece. Perfectly functional, but not a good look.

The elastic cords suspending the cargo divider at the top of the boot space feel as insubstantial as the thin metal hooks they’re attached to, and the finisher matt sitting on top of the engine looks like it won’t stand the test of time. 

There are other examples, but suffice it to say, the overall feel is not in the same league as this car’s main competitors.

BMW has found yet more grunt lurking in its trusty 3.0-litre 'M TwinPower' six-cylinder petrol engine, with the M4 CS now pumping out 405kW and 650Nm.

That's a decent jump from the 390kW and 620Nm served up by the M4 Competition, and a giant leap from the outputs of the 'base' M4 – 353kW and 550Nm.

Predictably, then, the CS is the fastest of the lot, knocking off the run from 0-100km/h in 3.4 seconds, compared to 3.5 and 4.2 in the Competition and M4, respectively. The top speed is also dialled up to 302km/h.

All that power is channeled through an eight-speed automatic and sent to all four wheels on demand, with the help of an 'Active M Differential'.

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.

The M4 CS is fitted with a 59-litre fuel tank, which – given the BMW's official fuel claim of 10.2 litres per hundred kilometres – should deliver a driving range on a full tank of 541 kilometres.

But... BMW also says the regular M4 – you know, the one that makes 52 fewer kilowatts and 55Nm less torque – uses 10.1L/100km, so do with that information what you will.

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.

The hardest and angriest M4 of all time is, perhaps unsurprisingly, hard and angry. This is a race track specialist, but because I don't happen to own one of those, my first experience with the barking (and barking mad) M4 CS was navigating my way back from BMW's inner-city dealership.

Like it or lump it, you're going to read some Porsche comparisons here, because you're talking not too far off base 911 Carrera money, and suddenly I find the two Germans doing battle for a spot in my dream garage.

First things first, the BMW won't be much chop for daily driving for most people. Happily, I have a sickness for uncomfortable sports cars. It tells me that no compromises have been made in the pursuit of punishing performance.

A good thing, too, because the BMW, at city speeds, can be punishing. Everything feels heavy, the seats aren't overly comfortable – especially the hard bits that tend to dig in when cornering – and it stiff-arms its way over road imperfections, that exhaust booming and barking as it does.

Again, I loved it, and you probably will, too. But it's still not the kind of car I'd relish sitting in the morning peak hour rush in.

But escape the confines of the city and the BMW M4 CS suddenly makes a whole heap of sense. The acceleration is genuinely brutal, and wonderfully theatrical, with that quad-tipped titanium exhaust barking and snarling as you rocket towards 100km/h.

The steering is brilliant, with feedback fed to your wrists via that thick-rimmed wheel, and the entire experience feels sharp, super engaging and edgy.

You can push the M4 hard and fast, and I'm certain my limited talents would run out far before the BMW's would, but there's this thrilling sense of peril sparked by the aggression of the experience, that I love.

It's like the magic of a roller-coaster, I guess. Even if you know nothing is going to happen, you never really know, right? And in that lies the magic.

But back to original question, this or a Porsche 911? There's no doubt a Carrera is a better all-rounder, in terms of comfy commuting and race track fun, but this angry M4 is all shouty theatrics, all of the time.

I bloody love it.

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.

The Citroen C3 scores four out of five ANCAP stars courtesy of testing dating back to 2017.

The sticking point was a sub-par result in Pedestrian Protection, one of the independent safety body’s four main assessment areas (beside Adult Occupant Protection, Child Occupant Protection, and Safety Assist).

Specifically, potential pedestrian head injuries resulting from contact with the base of the windscreen and “stiff” windscreen pillars.

But Citroen hasn’t left the C3 standing still with active (crash-avoidance) tech fitted to the current model including the usual suspects like stability and traction controls as well as more sophisticated systems like ‘Autonomous Emergency Braking’ (AEB), forward collision warning, blind-spot monitoring, lane departure warning, ‘Driver Attention Alert’, a reversing camera (with zoom function), and tyre pressure monitoring. 

That said, although there are parking sensors front and rear, there’s no cross-traffic alert (front or rear), no adaptive functionality on the cruise control, and no lane change assist. Arguably unrealistic to suggest all of these should be included at this price point but it’s worth noting not all boxes are ticked.

If a crash is unavoidable there are six airbags on-board (driver and front passenger front and side, plus full-length side curtain). The hazard lights automatically activate when emergency braking force is applied, but multi-collision brake, which reduces the chances of further impacts after an initial crash, is missing-in-action.

There are three top tethers for child seats or baby capsules across the back seat, with ISOFIX anchor points in the two outer rear positions. 

The M4 CS is covered by BMW's five-year, unlimited-kilometre warranty, with condition-based servicing available in packs, which will cost you $3530 over five years/80,000km, or $2900 over four years/60,000km.

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!
