Citroen C5 vs Isuzu D-Max

What's the difference?

The C5 Aircross might seem like a niche European 'alternative' SUV, but I wish it wasn’t. The more mainstream players could learn a lot from how brilliantly this Citroen is packaged.

It is truly class leading in terms of passenger comfort and even luggage space, even shipping with great multimedia and safety in this base Feel grade.

Unless you really need to be towing, performance (or in this case, lack thereof) should be low on your SUV priority list anyway.

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 wouldn’t be a French car without a solid dollop of style, and the Aircross has heaps of it.

From the orange paint, to its floating rear light fittings and chevron emblazoned grille, the Citroen is nothing if not unique.

Just like the C4 range before it, the C5 Aircross inherits the plastic 'airbump' fittings under the doors, with the plastic-clad soft-roader look continuing over the wheelarches and across the C5’s front and rear.

There’s a lot going on, on both the front and rear of this SUV, but somehow it’s not really over-complicated, all the flourishes and highlights manage to flow into each other to maintain some semblance of consistency.

The C5’s rear is a little more tame, with body coloured panels contrasted with the plastic strip, gloss black highlights, and dual-square exhaust facades. The floating gloss-clad roof rails are a flashy if silly touch.

I’d personally argue it’s a better-looking car than its Peugeot 3008 sibling, although it looks built entirely for city-slickers rather than the adventurous type.

Inside it’s normal. For a Citroen. Gone are the days of floating steering wheels or overtly wacky instrument clusters, it’s all quite tame and that’s for the betterment of the brand.

That’s not to say it’s not a cool place to be, and I was surprised to find myself surrounded by classy fittings, quality soft-touch materials and an understated blocky design theme. The C5 gets a small, oval steering wheel which feels great in the hands.

Those awesome memory foam seats are finished in a slightly odd grey synthetic denim kind of material. Some hated it, but I thought it contrasted the car’s exterior and interior schemes well. The raised centre console gives front passengers an extra secure premium sort of feel.

The grey materials will be slightly divisive, but the number one annoyance for me was the complete lack of tactile buttons for adjusting the climate control or media functions. Is a volume knob too much to ask?

Other than that, the C5 has one of the most tame, practical interior treatments on any Citroen… possibly ever… without managing to be boring.

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’.

The C5 Aircross is one of the most practical SUVs you can buy in this segment in terms of interior space. There’s just loads of it, and plenty of smart features to back it up.

In the front you get some small trenches in the doors, lovely big cupholders in the centre console, along with a top-box which was a little shallow, but still handy, as well as a small cavity (seemingly designed to hold the key) and a big bin for stowing your wallet or phone.

Back seat occupants get decent leg and headroom, but what’s really special here is each passenger gets their own memory foam seat with enough width to travel in decent comfort. The centre passenger’s legroom isn’t even impeded by a big transmission tunnel.

Rear passengers also get pockets on the back of the front seats, dual air vents, small cupholders in the doors, and a 12-volt power outlet. With no drop-down armrest, it would be nice to see more practical cupholders in the door cards.

The boot is truly gigantic. Like, biggest in the segment gigantic. At a minimum it weighs in at 580L (VDA), but as an added boost, the rear passenger seats can be slid forward on a rail to grant a whopping 140 extra litres of space to 720L. With the rear seats down you’ll be able to make use of 1630L.

A power tailgate, able to be operated by waving a foot under the car is also standard, revealing a totally unimpeded aperture. So, not only does it have a class leading luggage area, but it’s also easy to use.

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.

Pricing is up across the board for D-Max (and its MU-X sibling) regardless of drivetrain, but we’ll stick to the 2.2-litre variants here to stay on track.

Most of the lower-level D-Max variants are $1500 more than the previous equivalent, and with the manual gearbox dropped, the cheapest grade is the 4x2 single-cab chassis SX with a 2.2L engine at $36,200 before on-roads.

You can get the SX in crew-cab with a chassis or ute back in either 4x2 or 4x4 with a 2.2L engine, which is also available in the LSM X-Rider 4x4. 

That one will set you back $59,500, which is still far from the most expensive D-Max around. That’s still the Blade, with a 3.0-litre engine and 4x4 only, but it’s now $80,900.

Back to the 2.2s, and the SX grade comes with the basics. Cloth upholstery, polyurethane steering wheel and gear selector, vinyl flooring and even halogen lights.

There’s basic air-conditioning, but it does have a HEPA filter, and rear vents for crew-cab models, plus there’s wireless Apple CarPlay and Android Auto, auto wipers, and USB-C power ports as well as a USB-A port.

The central multimedia touchscreen is 8.0 inches, but the driver display is a little 4.2-inch unit between physical dials.

Stepping up to the LSM X-Rider brings with it auto-levelling LED headlights and LED daytime running lights, black styling trim, nicer cloth trim upholstery and gloss black 17-inch alloy wheels.

The rest of the D-Max line-up is 3.0-litre-only, and remains as it was before.

The C5 Aircross is powered by just one powerplant no matter which grade you pick. It’s a 1.6-litre turbocharged four-cylinder petrol engine, producing 121kW/240Nm.

It shares this engine with the Peugeot 3008 and the outputs compare well with the Renault Koleos’ Nissan-sourced 2.4-litre four-cylinder engine (126kW/226Nm) considering it’s much smaller and (theoretically) less thirsty.

The ever-smart Skoda Karoq is tough to beat in this segment with its 1.5-litre engine (110kW/250Nm) putting strong torque figures on the board.

The C5 Aircross sends power to the front wheels only via a six-speed automatic transmission, for a comparison the Koleos has a lackluster CVT auto, while the Karoq benefits from a seven-speed dual-clutch automatic.

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 1430kg C5 is rated to consume 7.9 litres of mid-grade 95RON unleaded per 100km.

That’s about on-par for the segment, and in practice I managed a figure of 8.6L/100km. A litre over isn’t too bad for truly mixed driving.

The mid-grade fuel requirement is a bit of an annoyance, but it’s also to be expected from a small capacity turbocharged European engine. It’s primary competitors (with the exception of the Koleos) drink the same.

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.

Straight up, the C5 Aircross is not the most exciting car you can drive. It’s not even exciting for the segment, with the focus being refreshingly distant from sporty.

You’ll be getting sluggish acceleration comprised of an occasionally lazy six-speed auto transmission and a dollop of turbo lag every time you depress the accelerator pedal.

But the C5 Aircross is, refreshingly, not about being sporty at all. I’d argue Citroen is one of the few carmakers that really ‘gets’ what driving an SUV should be about. Comfort.

See, this SUV more than makes up for its lackluster performance by being possibly the nicest place to be behind the wheel in the segment.

We’ve covered how unreal the seats are in terms of their quality memory foam padding, but it doesn’t end there. The C5 has the same excellent well balanced steering from the rest of the Citroen and Peugeot passenger car ranges, as well as sensibly-sized tyres on small alloy wheels and the hydraulic cushion suspension.

It all adds up to a ride that’s quiet and makes most road corrugations, imperfections and potholes a complete non-issue.

The suspension does have its limits, hitting a particularly sharp bump or pothole will have the car bouncing off its shocks, but it’s simply awesome on 90 per cent of Australian urban roads. I wish more SUV mid-sizers rode like it.

It’s also super quiet thanks to “extra insulation” in the engine bay and the small alloy wheels.

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. 

Isuzu has done well to include pretty much the full range of safety features across all its variants, with the SX only missing out on rear parking sensors - it still has a camera though, obviously.

Key features like rear cross-traffic alert with braking and adaptive cruise control are standard, plus the D-Max achieved a five star crash safety rating from ANCAP, even though that was under slightly easier testing back in 2020.

The biggest (but only) gripe on-test with the D-Max’s safety gear was its lane-keep during adaptive cruise. There seemed to be a need for the ute to sit close to either the centre line or shoulder during cornering, which led to some discomfort on fast country roads.

All current Citroens are covered by a five-year/unlimited kilometer warranty, matching the widely accepted industry standard.

That’s all well and good, but it’s the very erm… European service pricing which is the killer here.

The C5 Aircross is covered by a capped price servicing program which costs between $458 and $812 per yearly visit, for an average of $602 per year for the life of the five year warranty.

It’s a bit of a let down given the Citroen’s cheapest fixed-price service is the equivalent to an expensive service at more mainstream brands.

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.
