Citroen C4X 2024 long-term test

Both models were supremely relaxing, and the seats – leather in the electric car, Alcantara in the petrol – were among the plushest I've sat in. Ride comfort was excellent in both Citroëns, allowing the car to traverse the mountainous speed bumps near my apartment block without an accompanying orthopaedic emergency.

There was always more than enough room inside too, and on the several occasions I carried back-seat passengers, reports from the rear cabin were positive. Boot space was sizeable, although it's not entirely practical if you're loading it anywhere near the bootlid's hinged arms.

They often got in the way of larger suitcases and bags, meaning I'd have to reshuffle my luggage after painstakingly stacking it up. That aside, there was not much between the two cars in terms of overall boot volume, with the ë-C4 X's battery 

The gripes I did have appeared across both models. These included the infotainment system, which was responsive enough but confusing when trying to navigate quickly.

The digital driver’s display behind the steering wheel, meanwhile, is a bit too small for my liking, and some of the information was cut off the perimeter of the screen.

I usually just stuck with the head-up display. But even that suffered a graphical glitch, specifically when cruise control was activated, in the form of a large, empty blue square covering half of the display.

Wireless Apple CarPlay proved a godsend, as did wireless phone charging. Also useful were the numerous storage compartments dotted around the car, so effectively concealed that I once lost my keys in them (my fault, not the car’s).

So which C4 X would I prefer to buy? I’m afraid the answer comes down to price. The C4 X petrol starts from £18,775 in entry-level You! specification (£27,965 for our Max-trim test car), while the EV opens at £36,510, nearly twice the price.

That’s quite a saving if you choose the petrol, which would go a long way in fuel costs or even optional extras. Perhaps the best way to buy an ë-C4 X would be to look for a used one: prices for some nearly new examples have already dropped to below those of factory-fresh petrol cars.

You will stand out in a C4 X, whichever one you opt for: in my time with it, I saw no other electric versions and perhaps one or two petrols. But I did notice many more hatch-bodied C4s, so it’s clearly still the more popular choice.

Purchase price aside, I’d lean towards the petrol simply because of the EV’s unremarkable range. I’d usually get no more than 220 miles on a charge, while the petrol would furnish me with around 400 miles per tank at a consistent 50mpg.

While the ë-C4 X’s range will be enough for many drivers, it was more challenging for me given I don’t have access to a home charger and so would usually drive with the air conditioning and heater turned off to preserve battery, often to the annoyance of my passengers.

Ultimately, though, the C4 X is endearing with either a petrol or an electric powertrain, and the past few months have been the most comfortable I’ve experienced driving in a long while. But those reliability quirks may put some off – unfortunately, me included.

Second Opinion

Jack’s tribulations with the C4 X are a shame, because it is an appealing car: soft and pliant with a relaxed gait for long-distance work and the feeling of more power than its numbers suggest. And it’s quite good value. But would you buy one over a Golf? I know one person who wouldn’t…

Love it:

Comfort The seats in both the EV and petrol C4 X were cushioned and extremely comfortable.

Max specification Wireless charging paired with wireless Apple CarPlay was a perfect combination.

Performance Punchy powertrain always provided more than enough performance when it was needed most.

Loathe it:

Boot hinges The design of the hinged boot arms affects load space more than it should.

Electronics Software issue or not, no car should lose its vital systems when in a precarious position.

Life with a C4 X: Month 5

Broken - 26 June

Remember when Mark Tisshaw’s Jeep Avenger lost power to most of its electrics while he was driving on the M25? I was on the M4 when similar happened to my C4 X. All of its digital screens (the touchscreen, driver’s display and head-up display) switched off and never came back on. I now can’t see how fast I’m going or how much fuel I have left, so it will need to be recovered

Whoever said hatchbacks were more practical than saloons? - 12 June

I've not got long left with our Citroën C4 X, so I'm trying to make the most of its practical nature. Our test car has gone up and down the country on various jobs, including ferrying luggage to Gatwick and Heathrow airports, shipping four people plus their belongings on a family holiday and even a house move.

With that, let's reflect on the positives. I initially thought the sloped rear window would cause me problems, but it has been completely fine: the commodious boot is more than big enough for most occasions, with 510 litres of space (the same as in the e-C4 X) regularly filled to the brim with footballs, suitcases and weekly food shops.

There's plenty of additional storage space too, particularly in the front. The door bins are sizeable and there's a useful hidden compartment beneath the wireless phone charger. In fact, said compartment is so effectively camouflaged that I lost my house keys, the buzzer for my apartment complex's car park and a fresh pack of chewing gum all in the same night. After frantic searching and bugging my housemates to let me in for an entire week, I embarrassingly found that it had swallowed up all three items. Good luck to any thieves, I suppose...

Not everything is pertect, though. The bootlid hinges are solidly connected to the inside of the boot, meaning you need to arrange everything carefully. In my early days with the car, I kept forgetting this and blindly loaded up the boot only to find that some of my things were preventing it from closing. After a while, I started forgoing the boot altogether and chucked my gear on the back seats instead, which obviously isn't as secure or private. The boot entry is also fairly narrow and loading heavier items isn't made any easier by the high loading lip.

These quibbles aside, the C4 X has been an accommodating companion, and while I think it might sacrifice some of the C4 hatchback's good looks for that additional 130 litres of luggage space, it's probably the more useful version for long-distance travel.

Love it

Unusually relaxing

After testing other cars, the C4 X welcomes me back each time to a plush and peaceful environment.

Obstructive arms

The boot may be larger than in the C4 hatchback, but those hinge arms can be a real nuisance

Petrol C4 X still majors on practicality - 15 May

Spring weather is great for bike rides, with sun, dry roads and reasonable temperatures. But you need to watch out for thorns from freshly cut hedges or you’ll suffer a puncture, like my sister did. No panic: a road bike fits perfectly into the back of the C4 X with the seats folded down. It’s showcasing its practicality once again.

For every pro of switching from electric to petrol there is seemingly a con - 1 May

As the petrol C4 X is largely identical to the electric -C4 X, my transition from one Citroën saloon to the other has been smooth.

It remains a very comfortable place to sit, as practical as ever and as easy to drive, making my routine travels between London and Berkshire a doddle.

I mentioned previously that I was curious to see how the ICE car would compare in terms of relaxation, isolation and quietness, which the EV excelled at. Well, several hundred miles later, it's clear that it's a mixed bag.

The ride is equally pleasant as in the EV - soaking up most bumps and divots easily - but the engine feels strange in a car like this.

The 1.2-litre three-cylinder turbo Puretech unit under the bonnet here is actually the same as the one in my first Autocar long-termer, a 2021 Vauxhall Mokka.

While the -C4 X's electric powertrain was silent and composed at all times, this petrol one is loud and bizarrely pumps some artificial engine noise into the cabin.

Not that it's an unpleasant sound (it gives muscle car vibes, sort of, but it doesn't hurt this Citroen's laid-back, comfort-focused profile. The C4 X's automatic gearbox is similar to that in my old Mokka, too.

I complained about it at the time for being too slow to react off the line, and that's the case again here. As it is with the frustrating engine start-stop function.

Low-speed driving is also ript quite as easy as in the e-C4 X, which essentially has no gears at all. This means going through the capital at 20mph now requires me to focus more closely on the speedometer.

Thankfully, the C4 X makes up for this on longer drives. It's brilliant at 70mph - and quite efficient too. Several times it has achieved more than 50mpg, and a recent fill-up of its 50-litre tank prompted a prediction of 475 miles on the digital driver's display.

That prediction will constantly update and change throughout your journey, depending on how you are driving. I left Hungerford on one trip with 475 miles on the screen, but after travelling 75 miles it had increased to 520 miles. On another trip, it rose from 285 to 350 miles. And I thought, post-EV, range anxiety would be a thing of the past.

Love it 

Feels like a race car

The ë-C4 X’s faux-leather seats were comfy, but the Alcantara upholstery in our car makes the C4 X feel far more premium.

Loathe it

Annoying touchscreen 

It’s distracting to use and swipe through Citroën’s menus on the move. Thankfully, wireless Apple CarPlay is included as standard.

Frustrating gear selector returns - 24 April

The gear selector is the same in my new petrol C4 X as in my old electric ë-C4 X. Sometimes it takes several presses before it decides to switch, which can make manoeuvring quite frustrating. It’s a Stellantis parts bin item that features on most of the model range, though, so there’s no escaping it.

Easygoing electric crossover makes way for something completely similar - 10 April

Can you believe we're already into April? Well, the intermittent showers confirm as much, and I started my spring cleaning with the inside of my e-C4, as a man from Citroen was coming to swap it with a petrol-engined version of the same model.

I mentioned before how the general vibe of our electric saloon/ hatchback/crossover was genuinely relaxing, and I still think that today. From charging its battery to taking long-haul trips to the coast, it was a pretty easy thing to live with.

Outputs of 134bhp and 192lb ft of torque were always enough for me. The e-C4 X took a relatively pedestrian 10sec to get to 60mph, but I didn't feel like it needed to be quicker. Most of the time I would just stick it into Eco mode, sit back and cruise.

That said, range was hit or miss even in that most frugal setting. Shorter city drives would match with ease the advertised efficiency (which leads to the 221-mile official range), but stride out onto a motorway and that figure would soon plummet.

One time I dwindled the battery down to 10%, which, according to the digital driver's display, equated to just 14 miles left in the bank. I know it's all dependent on driving style, speed and weather, but if 10% equates to 14 miles, that's just 140 miles in all, which is some way below the claimed average. It's also an average of around 2.8mpkWh, which is poor compared with some other, heavier EVs I've driven before, including the BMW iX1 and even the Ssangyong (now KGM) Korando E-Motion.

However, it's important to note that while the Ssangyong was, like the Citroën, run through winter, I had the BMW through the peak of summer, when EVs are expected to perform far better in terms of efficiency. The -C4 X definitely felt its lack of a heat pump.

Excuse me while I bore you with some numbers. In total, over the past four months, I spent £453.94 charging the -C4 X. More than half of that (£285.98) came from a 7kW Pod Point home charger, £130.77 from Gridserve fast chargers, £22.86 from Chargemaster units and £14.33 from a Tesla Supercharger.

Additionally, in all my time with the car, I didn't encounter a single charger failure or error, which I think is a testament to how our charging network is strengthening - although maybe I just got lucky, given my Poor luck with the iXl before. Another caveat here is that the Citroën wasn't the most exciting car to drive - but then you could probably guess that just by looking at it. And as London is now blanketed by not only a 20mph speed limit but also a heinous epidemic of potholes, I wasn't too upset by this.

Overall, I found life with the e-C4 X to be simple and stress-free if largely unexciting, and I'm intrigued to see if it will be the same with my new CA X. I'm curious about the move not least because one of the EV's best qualities was its interior isolation and quietness, which I believe are best served by an almost-silent electric powertrain.

Citroën offers the internal combustion-powered C4 X with a choice of petrol and diesel engines. The petrol, which uses the Puretech 1.2-litre three-cylinder turbo unit familiar from across the Stellantis line-up, comes with either 98bhp and a six-speed manual gearbox or 128bhp and an eight-speed automatic. The diesel is a 1.5-litre BlueDi four, also with 128bhp and an eight-speed auto 'box.Perhaps the bigger draw for the petrol C4 X is its price. The entry-level You specification, which is available only with the 98bhp petrol engine, is priced at just £19,322, which is cheaper than a Volkswagen Polo and buys you a much more spacious and comfortable car.

My car, in range-topping Max specification, is priced at £25,820, which gets a suite of advanced safety technology, adaptive cruise control, front and rear parking sensors with a reversing camera, automatic adaptive headlights and an electrochromic rear-view mirror, which should help me see a bit better at night.

Ultimately that's a lot of car for the money, and it's around £10,000 less than the EV, if you were to buy it new. I say that because secondhand values of electric cars have plummeted over the past year or so, meaning many drivers might well be tempted to buy a used e-C4 X.

At the time of writing, a major car auction site has 114 examples on sale - with a handful coming in at less than £20,000. Several of those have never been driven, except to leave the factory. It's pretty staggering to see, especially when you can find in excess of 20 barely run-in examples of the e-C4 - the e-C4 X's regular hatch sibling - for less than £16,000.

I've also never seen another C4 X on the road. It seems the hatchback version is far more popular. Either way, I'm now in a petrol saloon for the next few months. Watch this space as I get to grips with all it has to offer.

Electric tailgate is a missed feature - 21 March 

It’s no doubt a premium feature, but I do miss having a powered tailgate. This saloon is quite low to the ground and I’m 6ft 2in, so I have to bend awkwardly to reach the release button down by the bumper. That said, the lowness does make it easier to load the boot with luggage.

Is this EV twice as good as a petrol C4? Jonathan Bryce isn't convinced - 3 March

Having driven and liked the Citroën C4 in petrol guise, I was intrigued to see if the electric version could continue the trend, which meant borrowing Jack Warrick's -C4 X saloon for a week.

It was clear very early on that it was one of the most comfortable cars I've driven. But is it a good electric car? I'm not so sure. Initially, I was pleasantly surprised to find it had a very practical interior, with enough space to store all my office jetsam.

For instance, the door pockets are cavernous and there's even a coat hanger that pops out of the dash. It makes me think Citroën had high-mileage fleet drivers in mind during development.

If you're looking for a car to simply let you get in and drive away, though, the -C4 X (or at least our ë-C4 X) isn't the most welcoming. I pushed the starter button once and nothing happened. I pushed it again and still nothing.

A third time? You might get something (I often did, but a fourth try is never far off. And I was not alone in having this issue: colleagues have struggled with temperamental electronics, too.

I was also fighting to navigate an ergonomically troubled dashboard. Wrapping my head around Citroen's infotainment was difficult at first, and I didn't even notice the 'home' menu on the touchscreen until after three days with the car.

Even then, I only found it because somebody showed it to me. I assumed the button with a house symbol next to it would take me there, but after I pressed it, the screen did nothing

The car redeemed itself on day two, however. I had to get to Gatwick airport, which meant motorway driving and bumpy surfaces that would put the suspension to work.

I had heard good things from my colleagues, and suffice to say I wasn't let down. The e-C4 X soaks up bumps and potholes with a measure of relaxation that almost makes it characterful.

Meanwhile, the light steering makes it very easy to manoeuvre, if you can forgive the lack of engagement. It also has a boot big enough to swallow a large suitcase and several jackets, at 510 Litres, although the opening could do with being wider.

The cars range wasn't a huge concern that day, because it was a relatively mild morning (8deg C) and the driving was mostly on motorways. On the 52-mile round trip, I stayed below 65mph and it averaged 4.0mpkWh. I returned having reduced the trip computers range prediction by around 80 miles. Not the best.

I felt strong range anxiety a couple of days later. I was due to travel a 94-mile round trip to Bicester Heritage and made sure I left with a full charge. The car predicted 216 miles.

I wanted to see how far I could go without using any of its battery-draining systems, like the air conditioning and radio, and I stuck to 56mph the whole time on the M40, even slipstreaming trucks.

It was uncomfortable (I could see my breath most of the way), dull and not worth the hassle. I arrived at Bicester with a predicted range of 123 miles, so I had used 93 miles on a 47-mile trip with everything switched off. Oh dear.

A difficult pill to swallow, then, and it's made worse by the fact that this car costs nearly £40,000 - twice as much as the £19,495 petrol C4.

Love it 

Can kick back

It’s supremely comfortable and relaxing on long distances, so long as you know when and where you will be able to charge.

Loathe it

But can't relax

Cold weather and speeds above 65mph make the range drop faster than an anchor.

Life with an E-C4 X: Month 1

Outstanding comfort and superb urban efficiency make for a happy commuter - 21 February

The e-C4 X's comfort levels are really impressive.

In fact, Id go so far as to say it's one of the most relaxing cars I've driven. Not only are the seats plush and comfortable but also the cabin is well insulated from road and wind noise.

Even on the most stressful roads (looking at you, London's North Circular), the silent powertrain and easy-going steering make life much more serene.

This has made my crack-of-dawn journeys from north London to the Autocar office in Twickenham a particularly easy task - and the French EV's efficiency bolsters its pacifying credentials even further. On my 20-odd-mile urban commute, it regularly returns 4.5mpkWh.

With the battery having a usable capacity of 46.2kWh, that means it returns a range of around 208 miles on a single charge. Considering that I drive around with the air conditioning on (albeit on the lowest fan speed setting), I'm pretty happy with that figure.

Overall, it's averaging around 3.9mpkWh, which translates to a slightly more disappointing 180 miles of range on a charge.

But I have been quite lucky. This winter has been relatively mild, so I've not needed to crank up the climate control to clear ice from the windscreen, warm up the cabin or demist. I do wonder how badly the range will be affected if temperatures drop below zero - something all EVs really hate.

The e-C4 X is at its best in Eco driving mode, rather than Normal or Sport. Not only do you gain an additional 20 miles of predicted range as a result but there's also still ample acceleration and enough power for cruising at 70mph. It's perfect for London's 20mph zones.

While the cabin is all about driver relaxation, I've had some issues with its technology. The infotainment system is a pain to use on the move, because everything is navigated with onscreen swipes and drag gestures and the voice assistant pops up while I'm chatting with my passenger.

The resolution of the digital screen behind the steering wheel is also really poor compared with what you see in new cars from other Stellantis brands. It even cuts off some of the text on the right-hand side of the screen when you've plugged the car in to a charger.

I instead mostly just refer to the digital head-up display, which shows me all the information I need - even if, at 6ft 2in, I am slightly too tall for it.

Love it 

X-Rated

The 510-litre boot is a decent size and some 130 litres bigger than that of the ë-C4 hatchback.

Welcoming the E-C4 X to the fleet - 7 February 2024

The Citroën e-C4 X is a hard car to classify, even when you've spent a bit of time with one, as I have since ours arrived on the long-term test fleet.

The EV sits intriguingly within the increasingly blurred lines that separate different car categories, riding slightly higher than a traditional saloon but not quite by enough that you could call it an SUV. Coupé-SUV hatchback?

Raised fastback saloon? One of those descriptions is probably correct. Citroën itself calls the car a "fastback with the modern look of an SUV", so that's cleared that up...

One absolutely clear thing is that Citroën has stayed true to its comfort-biased roots because the e-C4 X has already made a case for it being among the Stellantis group's most relaxing cars to drive.

This electric fastback prioritises comfort above all else - a point emphasised by its gloriously plush seats and bump-absorbing ride.

To that end, it's equipped with the French brand's Advanced Comfort suspension, which features dual hydraulic stops at the front and rear. In some ways, it feels like a Rolls-Royce Spectre for the everyman.

Okay, so obviously it's not going to be taking on the £330,000 ultra-luxurious Spirit of Ecstasy in any forthcoming comparison tests, but it is jolly nice inside and it comes with a 10.0in touchscreen with wireless Apple CarPlay and Android Auto, plus a crisp head-up display, as well as a 5.5mm digital screen behind the steering wheel.

It feels very quiet on the move too. There are no rattles inside, road noise is kept to a minimum and I've struggled to detect the sound of wind rushing past, even on faster roads.

The C4 X uses the same e-CMP platform as several other Stellantis models, including the DS 3, the Peugeot 2008 and the smaller Vauxhall Corsa, and it also shares much of its internals with the electric versions of those cars.

You could even, in effect, think of this car as an electric version of the Peugeot 408, which was run by chief sub-editor Kris Culmer towards the end of last year.

Anyone eyeing up an -C4 X is probably looking for an EV with practicality in mind, and it doesn't disappoint on that front. There's 510 litres of boot space with the rear seats raised and that increases to 1360 litres when they're folded. That compares favourably with the 425 litres offered by the Tesla Model 3 and the 405 litres of the Polestar 2.

There's room for three adults to fit comfortably in the back too. Where the e-C4 X is widely outclassed, though, is on range. Its 50kWh battery (46.2kWh usable capacity) is claimed to offer just 221 miles on a single charge, although Citroen says this can rise as high as 303 miles in the city. That's a figure I'll certainly be putting to the test, because my driving will be split mostly between London use and longer stints on the motorway.

Power looks relatively modest on paper as well. A single, front-mounted permanent magnet synchronous motor supplies 134bhp and 192lb ft of torque. However, so far I've found it to be more than adequate in most situations. It helps that the 1623kg kerb weight is fairly light for an EV.

Besides, the e-C4 X is a car to be driven in a manner befitting its aura of calm, rather than ragged around corners. It's certainly no driver's car and nor is it intended to be one, as its leisurely 0-62mph time of 10.0sec attests. In that respect, it will be a marked contrast to the 308bhp BMW iX1 that I ran most recently.

The e-C4 X is priced from £32,195 but in Shine Plus form starts at £35,495, rising to £37,140 with the options fitted to ours. Beneath this range-topping model are the more affordable Sense and Shine trims.

Owners get a lot of equipment for their money. In addition to LED headlights, a reversing camera, dual-zone climate control, automatic wipers and a heated steering wheel (which are all standard), our car features optional metallic paint, wireless smartphone charging and a tablet cradle to keep your passenger entertained on the move.

The optional Hype Black interior ambience pack fitted to our car is also worth mentioning because it's all very Citroën. It adds grey stitching, heated front seats, a plusher leather steering wheel, four-way adjustable electric seats and electric lumbar support and massage functions.

By spanning the saloon and SUV classes, the e-C4 X finds itself up against a huge range of competition from both segments. Our job over the coming months is to see if it's up to that task. First impressions suggest it could be a good option for those seeking an affordable electric company car, so that will be on our radar too.

And that's not all. While this electric version of the C4 X has been on sale since 2022, Citroen has now also decided to bring its internal combustion equivalent to the UK this year in response to customer demand.

So we plan to switch to a petrol car down the line, which should make for an interesting comparison of two comfort-driven sibling models. But we're in no rush to find out which C4 X is best. This simply isn't that kind of car.

Second Opinion

It flies under the radar and it’s so very comfortable – two favourable qualities compared with big, bulbous SUVs. I hope Jack has more luck in coaxing a decent range out of it, though. In my experience, it stopped far short of the manufacturer’s claim, even with ‘wasteful’ systems turned off.
