2019 BMW Z4 vs 2020 Citroen C5

What's the difference?

The Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

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 Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

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 Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

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 C5 Aircross enters Australia in just two spec levels, and the one reviewed here is the base Feel. Priced at $39,990, before on-road costs, it’s not exactly cheap, but is thankfully well specified.

And at the time of publication a Citroen drive-away pricing campaign pitched the Feel at $44,175 with all registration, dealer and other pre-delivery charges included.

In the box is a 7.0-inch multimedia touchscreen with Apple CarPlay, Android Auto, DAB+ digital radio and built-in sat nav, a 12.3-inch digital dash display, auto-dimming rear-vision mirror, auto headlights and windscreen wipers, keyless entry and push-start ignition, dual-zone climate control, LED DRLs, and an electric tailgate.

That’s the good. Not-so-good are the halogen headlights (kind of detracting from the slick front styling) and the lack of radar cruise control.

The Aircross does get a decent set of active safety features explored in the safety section of this review.

Competitors? Well there’s a good chance you’ll be cross-shopping the C5 Aircross against other alternate options in the mid-size space, including the Peugeot 3008 Allure (with which the Aircross shares an engine and chassis - $40,990), the Renault Koleos Intens FWD ($43,990), and perhaps the Skoda Karoq (just one spec-level in Australia - $35,290).

The Aircross’ secret weapon, which you can’t get on any other mid-size SUV, is its seats. Citroen calls them 'Advanced Comfort' seats, and they’re stuffed with memory foam “inspired by mattress technology.”

And it sounds like pamphlet hype, but it’s not. Once you’re seated, it’s like you're floating on air. A little bit of genius!

Citroen pairs this with reasonably-sized 18-inch alloy wheels and a unique suspension system which uses “progressive hydraulic cushions” (a nod to Citroens past) to soften the ride.

It’s a double down of comfort features, and really adds up to a lovely place to be behind the wheel. All for a similar price to its Peugeot sibling. Worth considering.

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

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.

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

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.

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

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.

The Aircross has the same set of active safety features no matter which grade you pick. This means auto emergency braking (AEB – works up to 85km/h) with forward collision warning (FCW), lane departure warning (LDW) with lane keep assist (LKAS), blind spot monitoring (BSM), driver attention alert (DAA), and traffic sign recognition (TSR) are all standard.

You’ll get the added benefit of front and rear parking sensors and a 360-degree parking view, which is excellent in its functionality.

Expected refinements include six airbags and the regular suite of electronic stability and brake controls.

It’s an impressive suite and has everything you’d expect in a new car – apart from the strange omission of active cruise control.

The C5 Aircross has not yet been rated by ANCAP (although its European full-safety spec equivalents have a maximum five-star EuroNCAP score).

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.

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.
