Mercedes-Benz A-Class vs Citroen C3

What's the difference?

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

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

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. 

Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

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.  

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

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.

The biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

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.

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

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.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

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 C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.

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!
