Isuzu D-Max vs Citroen C4

What's the difference?

The new engine makes the D-Max a much more likeable ute than it already was, which is high praise.

It’s smoother and quieter and makes for a more pleasant drive. The added efficiency is a bonus both for your wallet and Isuzu’s emissions credits.

The 3.0-litre engine will probably remain the favourite, but anyone who test drives a 2.2L might even be tempted to opt for the smaller unit. Isuzu sure hopes so.

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 look of the D-Max depends on the grade you end up with, but the 2.2-litre SX and X-Rider variants down the lower end of the model-run are still pretty standard-looking utes. Inside and out.

You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated. 

The black trim (and extra features) that comes with the LSM X-Rider as opposed to the SX is worth it if you’re keen to get a 2.2-litre-powered D-Max for the family rather than one for a fleet as it just elevates things slightly.

Inside, it also means nicer cloth, and not having the vinyl flooring looks a little less ‘farm ute’.

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.

The D-Max remains straight-forward inside, given nothing has changed with the update aside from the 2.2-litre engine and the addition of stop-start - there’s a button for that now.

The interior and usability of the D-Max, especially in the lower-end variants where the 2.2L engine is available, is focused on the basics.

Tech remains at a relative entry point, where the 8.0-inch screen and its software feel outdated but do everything you need. Plus of course there’s the phone mirroring workaround.

The D-Max is comfortable and spacious enough, there’s also physical buttons for everything including media and climate settings, and adjustability in terms of the seating position means not needing to reach.

In dual-cab versions, there’s enough space for an adult to sit in the second row behind another adult, so the D-Max also holds its own as a family hauler. Tick.

Importantly, Isuzu is now able to claim a 3500kg braked towing capacity across the full D-Max range thanks to the new 2.2-litre engine.

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.

In recent memory, Citroen’s offerings (the smaller C3 hatch in particular) have decidedly missed the mark on value. It’s not enough to be a niche player in Australia anymore – we have too many brands for that - so Citroen has had to have a re-think of its pricing strategy.

The resulting C4 that launches in Australia comes in a single, highly specified trim level, at a price that is remarkably competitive for its segment.

Wearing an MSRP of $37,990, the C4 Shine is positioned to compete with rivals like the Subaru XV (2.0i-S $37,290), Toyota C-HR (Koba hybrid - $37,665), and equally funky Mazda MX-30 (G20e Touring - $36,490).

For the asking price you also get the full list of available equipment, including 18-inch alloys, full LED exterior lighting, a 10-inch multimedia touchscreen with wired Apple CarPlay and Android Auto connectivity, built-in navigation, a 5.5-inch digital dash cluster, a head-up display, dual-zone climate, full synthetic leather interior trim, and a top-down parking camera. This leaves only a sunroof ($1490) and metallic paint options (everything but white - $690) as available extras.

The Citroen also packs some unusual items that represent surprising value – the front seats have a massage function and are stuffed with a very nice memory foam material, while the suspension system packs a set of hydraulic dampers to iron out the ride.

While the C4 faces tough competition in the small SUV segment, I think it represents pretty solid value at the price, so long as you’re chasing a virtue like comfort over hybridisation. More on that later.

The new 2.2-litre turbo-diesel four-cylinder comes with 120kW and 400Nm, that’s 10kW and 50Nm more than before. Isuzu also says there’s 60 per cent more torque ready from near-idle at 1000rpm.

An eight-speed auto replaces the six-speed, but the brand has also culled the manual options that remained in the line-up.

As ever, that sends power and torque to a part-time 4WD system capable of 2H, 4H and 4L with a rear diff-lock.

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 biggest advantage for the new drivetrain from Isuzu’s perspective is that it’s more fuel efficient.

The old engine’s 6.9 litres per 100km become 6.6L/100km in the new engine, in part thanks to a new stop-start system. That system is also now on the 3.0-litre engine, where 8.0L per 100km drops to 7.1L.

With its 76L diesel tank capacity, the D-Max should theoretically be able to travel more than 1000km on a single fill, although that comes down to a lot of variables - that 6.6L figure was achieved in almost lab-like conditions.

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.

Let’s start with the most important part of the updated D-Max. The new 2.2L is smooth. 

It feels so much more refined physically, but it's also quieter. Paired with the new eight speed, it makes the D-Max a much more likeable ute than it was with the rattly 1.9L.

At the launch, Isuzu had a bunch of MU-Xs to drive (keep an eye on a review coming soon), and the new drivetrain actually suits that big family SUV down to a tee.

The power and efficiency changes are second to how much it changes the characteristics of the thing.

If anything, the D-Max sits in a slightly higher gear than necessary, probably to try and eke as much out of the diesel dual-cab as possible in terms of fuel efficiency, but put your foot down and a more appropriate gear is close-by, and without much fuss.

There's also a relatively good stop-start system. It's not seamless but it's better than some. You take your foot off the brake and the engine rattles back to life, rather than waiting for you to put your foot back down.

The rest of the D-Max’s behaviour is pretty standard ute stuff, as it was before.

The steering is on the light side, but accurate enough even though it has a slightly doughy spot dead-straight. It’s not anything you wouldn’t expect from a ute.

Similarly, the brakes are a bit spongy but predictable, and once you’re used to where the ‘bite’ point is it’s easy to live with.

The suspension is a bit busy, but easy to keep on top of and doesn’t jostle you around. 

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.

There's not such a good story to tell here. While the C4 comes with today’s expected suite of active-safety items, it just fell short of a five-star ANCAP rating, scoring just four stars upon its launch.

Active items on the C4 Shine include auto emergency braking, lane-keep assist with lane-departure warning, blind-spot monitoring, adaptive cruise control, and driver-attention alert.

Some active items are notably missing, like rear cross traffic alert, rear auto braking, and more cutting-edge items like junction alert for the AEB system.

What cost this car its five-star rating? ANCAP says the lack of a centre airbag contributed, but the C4 also fell short on protection for vulnerable road users in the event of a collision, and its AEB system also had marginal night-time performance.

Isuzu’s six-year/150,000km warranty covers the D-Max, which could do without the limited distance, especially for a workhorse.

There’s also five years of flat-rate servicing every 12 months or 15,000km, costing $469 each time.

That’s gone up about $20 per visit since the update, with total cost over the five years at $2345.

There are 164 Isuzu dealers across the country, so finding somewhere to service shouldn’t be a challenge.

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.
