Citroen C4 vs Mercedes-Benz E53

What's the difference?

It’s weird, wonderful and fun, in more ways that one. I think every segment could use an oddball alternative like the C4. Citroen has successfully transformed it from a hatch to a small SUV with a difference. It’s not going to be for everyone – few Citroens are – but those who are willing to take a chance will be rewarded with a surprisingly competitive little package that stands apart from the crowd.

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

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

It’s really hard to stand out in Australia’s busy marketplace, especially in this small SUV space, where there doesn’t really seem to be as much of a design rulebook as there is in other segments.

Rooflines are wildly different, as are beltines and light profiles. While some may decry the fall of the hatchback to these more high-riding options, at least some of them are bringing fresh design ideas to the car world.

Our C4 is a great example. An SUV perhaps in profile only, it sports a slinky descending roofline, tall, contoured bonnet, a frowny-face LED profile, and characterful plastic claddings, which are a continuation of Citroen’s ‘Airbump’ elements, which gave cars like the previous-generation C4 Cactus such a unique look.

The rear is this car’s most confronting angle, with a post-modern approach to the light profile, and in reference to C4s past, a spoiler integrated into the rear tailgate.

It looks cool, contemporary, and I think is successful in its aim to blend the sporty elements from the hatch world with the sought-after high-riding elements of an SUV.

It certainly caught a few eyeballs in my time with it, and if nothing else, a bit of attention is something the Citroen brand desperately needs.

In the past you could rely on this brand to give you a funky interior, but one that sadly also came with its fair share of sub-par plastics and strange ergonomic. So I’m pleased to report that the new C4 dips into the better looking and feeling Stellantis parts catalogue for a still interesting yet more coherent experience this time around.

The modern look and feel of this car continues with interesting seat designs, a high-riding dash with a higher degree of digitization than before, and improved ergonomic features (even over some notable Peugeots). We’ll talk more about those in the practicality section, but the C4 feels as weird and different from behind the wheel as you’d hope , with an odd dash profile, a fun and minimalist steering yoke, and attention-to-detail elements, like a detail strip that runs through the door trims and across the seats.

These elements are welcome and help separate this Citroen from its Peugeot siblings. It will need this going forward, as it also now shares much of its switchgear and screens with its sister brand.

This is largely a good thing, with the 10-inch screen looking and feeling good and slotting into this car’s design nicely.

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable interior. 

The C4 brings some interesting practicality elements. There are a few areas where it’s even better than the improved layouts of recent Peugeot models.

The cabin feels spacious, with the C4’s relatively long wheelbase providing ample room in both rows. Adjustability is good for the driver, although it is worth noting that the seats have an odd blend of manual adjust for sliding fore and aft, contrasted with electrical adjust for seat height and tilt.

Comfort is superb from the memory-foam stuffed and thick synthetic-leather-clad seats. I don’t know why more cars don’t adopt this approach to seat design. You sink into these seats and are left feeling like you’re floating above the ground rather than sitting on something. The feeling here is unmatched in the small SUV space.

The massage function is a wholly unnecessary addition, and with the thick seat cladding, it didn’t really add much to the experience.

The seat bases aren’t too high either, unlike some cars in the SUV class, but the dash design itself is very tall, so people shorter than my 182cm height might find extra adjustment is required to see over the bonnet.

There are large bottle holders in each door with a very small bin; dual cupholders in the centre console, and a small armrest console box.

There’s also an odd little two-tiered shelf under the climate unit, with a removable base for extra storage underneath. It seems to me that the top shelf is a missed opportunity to place a wireless charger, although connectivity is handy with the choice of USB-C or USB 2.0 to connect to the wired phone mirroring.

A big win is the presence of a full dial set for not just volume but the climate unit too. This is something the Citroen scores over some of the new Peugeots, which have moved the climate functions to the screen.

Somewhat less wonderful are the digital dash cluster and holographic head-up display. These seem to be a bit redundant in the information they display to the driver, and the digital dash has no customisation, leaving me wondering what the point of it is.

The C4 also has some interesting innovations on the front passenger side. It has an unusually large glovebox and a neat little sliding tray, which looks like something from a Bond car.

It also has a slide-out tablet holder. This odd little thing lets you securely mount a tablet to the dash to provide a multimedia solution for the front passenger, which may be good for entertaining larger kids on longer journeys. Or adults who don't want to talk to the driver. It’s a neat inclusion, but I’m not sure how many people will use it in the real world.

The back seat offers a remarkable amount of room. I’m 182cm tall and had heaps of knee room behind my own driving position. The nice seat trims continue, as does the patternwork and detailing, which is the kind of attention to detail you don’t always get from rivals.

Headroom is a little limited, but you also score dual adjustable air vents and a single USB port.

The boot comes in at a hatch-sized 380-litres (VDA). It’s a neat, square shape with no little cutaways at the sides and is just big enough to fit our full CarsGuide demo luggage set, but leaves no room to spare. The C4 features a space-saver spare wheel under the floor.

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

Priced at $199,900, before on-road costs, the Mercedes-AMG E53 Hybrid 4Matic+ lines up against an interesting mix of internal combustion, hybrid and pure-EV contenders, the most closely aligned on spec and price being the BMW M4 M Competition xDrive ($201,300), Lexus LS500h F Sport ($199,250) and Porsche Taycan 4 Cross Turismo ($197,400).

And as you’d expect for a performance sedan on the cusp of $200K the standard equipment list is long. Aside from the performance and safety tech we’ll get to shortly, the E53 features four-zone automatic climate control, 17-speaker Burmester surround sound audio (including digital radio), Nappa leather trim (including the steering wheel) and the ‘MBUX Superscreen’ display consisting of three screens - 14.4-inch central media, 12.3-inch instrument/info for the driver and 12.3-inch for the front passenger.

You can also tick off the box on Android Auto, Apple CarPlay and Bluetooth connectivity, plus the power front seats (with memory) are heated.

There’s also a head-up display, panoramic sliding sunroof, ambient lighting, keyless entry and start, built-in nav, a 360-degree virtual top-down camera view, LED exterior lighting and 20-inch alloy rims. 

There’s more, but you get the idea. This car is loaded with included features that help it match or better its diverse competitive set.

There are four optional AMG packages available - The ‘Night Package’ ($3000) which includes aero-influenced body elements, special rims and more. The ‘Carbon Fibre Package’ ($6000), featuring a range of carbon bits including the exterior mirror caps, bootlid spoiler and interior pieces like the centre console and steering wheel. A ‘Performance Seat Package’ ($5000), which unsurprisingly focuses on racier front seats with integrated headrests. And the ‘Energizing Package Plus’ ($5300) adds ‘multicontour’ front seats that are heated (as are the centre console lid and door armrests) and individual fragrance for the interior, as well as ionisation of the cabin air.

The C4’s single trim level has a single engine, and it’s a good one; a peppy 1.2-litre three-cylinder turbo.

It appears elsewhere in the Stellantis catalogue and has been refreshed for the 2022 model year with a new turbo and other small refinements. In the C4 it produces 114kW/240Nm and drives the front wheels via an Aisin-sourced eight-speed torque converter automatic transmission.

No dual-clutches or CVTs to be found here. This sounds good to me, but is it good to drive? You’ll have to read on to find out.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

Despite the little turbocharged engine and the abundance of ratios in that transmission, the Citroen C4 disappointed me a little bit when it came to real-world consumption.

The official/combined consumption sounds reasonable at just 6.1L/100km, but after a week of driving in what I would consider realistic combined conditions my car returned 8.4L/100km.

While it’s not terrible in the wider context of small SUVs (a segment that is still packed with naturally aspirated 2.0-litre engines), it could be better.

The C4 also needs at least mid-shelf 95RON unleaded fuel and has a 50-litre fuel tank.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

Driving the C4 is an interesting experience because it approaches the road a little differently from most of its rivals.

It really leans into Citroen’s newfound comfort-focused niche with the seating and suspension. This results in an overall experience that is a bit unique in the market, and quite pleasant, too.

The ride really is quite good. It’s not a fully hydraulic system but has dual-stage dampers that essentially smooth out corrugations and much of the nasty stuff that comes into contact with the tyres.

It’s odd because you can hear the big alloys crashing about on the road, but ultimately you feel little of it in the cabin. What’s more impressive is Citroen has managed to imbue the C4 with this floating-on-the-road feeling, while maintaining enough of a ‘real’ driving position to make it feel like you’re sitting in the car and not on it.

The overall result is impressive. The comfort extends to the seats, as mentioned, which really do still feel floaty and supportive even after hours on the road. It also extends to the steering, which has a very light tune. This is a bit unsettling at first, as it feels like it has a large dead-zone in the centre, but it is also speed dependent, so once you’re cruising it regains a significant amount of feel. You can also manually bring back a bit of firmness by setting this car to its Sport drive mode, which is unusually good.

This means you can have an ease of operation in tight quarters while maintaining enough feel to make it fun to drive when you need to ask more of it. Clever.

Speaking of fun, the revised 1.2-litre three-pot is a hoot. It has a distant but entertaining gruff tone under pressure, and surges forward with just enough urgency to not leave you really wanting for power.

It’s not what I would call quick, but it has a raucous attitude paired with a well-behaved torque converter auto to make it truly entertaining. When you push it, there’s a moment of turbo lag followed by a lump of torque, which the transmission lets you ride out before decisively snapping into the next gear. I like it.

Again, it's not quick, but it punches just enough above its weight to leave you with a smile when you stick your boot in. To have that in a car otherwise so focused on comfort is an unexpected pleasure.

The dash cluster could use some work, as could visibility out of the cabin. The small aperture out the rear and tall dash line could leave some drivers feeling a bit claustrophobic. While the engine is fun to engage with, the turbo lag could potentially be a source for annoyance at times, too.

Brief negatives aside, I think the C4's drive experience really brings something unique, fun, and comfortable to the small SUV space.

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

The Mercedes-AMG E53 Hybrid 4Matic+ hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it comes up short in terms of crash-avoidance and passive safety tech.

It features a comprehensive suite of ‘Advanced Driver Assistance Systems’ (ADAS) features including ‘Active Brake Assist’ (Merc-speak for AEB), adaptive cruise control, blind-spot monitoring, lane-change and lane-keeping assist, front and rear cross-traffic alert, traffic sign recognition, driver attention monitoring, adaptive high-beam, ‘Park Assist’ (including front and rear parking sensors) and tyre pressure monitoring.

And if an impact is unavoidable the airbag count runs to 11 - dual front, front and rear side, full-length side curtains, driver and front passenger knee and a front centre bag.

As the name implies, ‘Auto Emergency Call’ will contact emergency services after a collision and there’s even the obligatory Mercedes first aid kit and high-vis vests. 

There are three top tethers for child seats or baby capsules across the rear seat with ISOFIX anchors on the two outer rear positions.

Ownership has always been a tough topic for unusual Euros like the C4, and that seems to continue here. While Citroen offers a competitive five-year and unlimited-kilometre warranty for all its new products, it’s the service costs that will hurt the most.

While most Japanese and Korean brands are competing to really keep these numbers down, the C4’s average yearly cost, according to the provided schedule, comes in at an average of $497 for the first five years. That’s nearly double the cost of Toyota’s C-HR!

The C4 Shine will need to see a service centre once a year or every 15,000km, whichever occurs first.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.
