Citroen Grand C4 Picasso vs Mazda MX-5

What's the difference?

The lack of third-row airbags and AEB could be enough for you to rule this version of the Citroen Grand C4 Picasso out of contention as a family vehicle. We’d understand that.

But there are plenty of other reasons that it could be a contender on your people-mover shopping list. It’s a largely thoughtful car in a small and beautiful package… no matter what badge is stuck on the back of it.

Ultimately, the design and tech changes to the ND MX-5 will be the biggest day-to-day advantages of the updated model, because the mechanical changes don’t make themselves hugely obvious on the road.

If you’re into track days, it’s still a satisfying car to hustle as fast as you can, but it’s at its most accessible on winding roads for weekend drives, where the new differential and track DSC mode won’t come into play as much.

But in a world where accessible sports cars are becoming a rarity, there’s only one rear-drive convertible with a sticker price appropriate for financial mortals, and it’s a pretty damn good thing that it’s the ND MX-5.

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

If you were to suggest there isn’t anything interesting about the design of the Citroen Grand C4 Picasso, it would pretty much intone that you’re vision impaired. This is - without question - one of the most intriguing and interesting looking vehicles on the market today.

With its front-end design mirroring the other models in the French maker’s range - sleek LED daytime running lights sitting either side of a chrome grille with central chevron, the main headlights below and some chrome trimming on the lower bumper - this is easily distinguishable as a Citroen. There’s no confusing it with a Kia, Honda, or anything else, in fact.

The large windscreen and panoramic sunroof help give it that two-tone look, and the beautiful silver C-shaped rim that surrounds the glasshouse is one of the best styling touches in the automotive business.

Our car rides on the standard 17-inch wheels wrapped in grippy Michelin tyres, but there are optional 18s if you want something that fills the wheelarches a little more. 

At the rear there are some nicely styled tail-lights, and its hips are broad, giving it a nice amount of presence on the road when you’re sitting behind it in traffic. 

I think Spacetourer works better as a name: Picasso was known for artworks that were challenging to make sense of. This vehicle presents no such conundrum.

The interior is also one of the most stunning in the business: I love the two-tone dashboard, the stacked twin screen layout, the minimalism of the controls and the massive windscreen with innovative adjustable headlining - yes, you can move the front part of the headlining back and forth, and the sun-visors move with it.

Our car had the optional 'Leather Lounge' pack, which adds dual-tone hide trim, seat massage functions for both front seats, plus heating for both front seats, and the front passenger seat has an electrically operated leg/footrest. This interior trim is nice, but it comes at a price… ahem, a big price: $5000. 

As you might expect, that’s hard to justify if you’re trying to save money on your seven-seat people-mover. But ignore that: let’s take a deeper dive into the cabin.

Alright, we’ve all seen ND MX-5s, you don’t need me to tell you about its proportions or explain its design elements to you in too much detail, so I’ll give you the headline changes.

At the front and rear are new pairs of LED head- and tail-lights, respectively… obviously, fitting into the spaces the old ones took up.

The DRLS and reverse lights have come off the bumpers for both, and are now part of the main lights at each end - no more DRLs in the front bumper, and the reverse lights have been replaced by reflectors.

There are new 17-inch wheel designs for the base and GT trim levels, too, and there’s a new colour - Aero Grey.

Inside, it’s a shame that the tan Nappa leather interior of the RF Black Roof can’t be had in a manual roadster, because it’s gorgeous, even though the inside still looks refined enough for a simple sports car in its base cloth trim.

It’s kind of amazing just how much Citroen has managed to fit into the Grand C4 Picasso. It measures 4602mm long - which is just 22mm (an inch) longer than a Mazda3 sedan! As for the other dimensions, the width is 1826mm, and the height is 1644mm.

How many seats does the Citroen Picasso have? The answer is seven, whether you choose the petrol or the diesel - but notably, the petrol model has a space-saver spare wheel under its boot, where the diesel misses out because it has an AdBlue system. 

Yep, by some marvel of packaging magic, the brand’s engineers managed to pack seven seats, a reasonable boot (165 litres with all seats up, 693L with the back row folded, 2181 with the five rear seats folded), plus a spare tyre and a lot of style into a very compact package.

That’s not to say this is a seven-seater to suit all the needs of buyers who want seven seats. The back row is tight for anyone nearing 183cm (six-feet) tall, and there is no third-row airbag coverage. According to the French brand, the occupants of those rearmost seats are inwards enough of the sides of the car that they theoretically shouldn’t need airbag cover. Depending on your safety stance, that may rule it out for you - or perhaps make you change your mind as to whether you use the back row regularly or not. 

Even so, there’s a huge amount of practicality to the cabin. You can fold the third-row seats and stow them away under the boot floor, or if you need to use them there are vents as well as a fan speed controller and a set of rear reading lights. The boot also has a light that doubles as a flashlight, and there’s a 12-volt outlet. There is one shallow cupholder and two small storage boxes on top of the wheel-arches.

In the second row the seats are also individually operable, with all three sliding and/or folding as required. The outboard seats also have a clever seat base flip-up function, allowing them to move all the way forward for easier third-row access. 

The space in the second row is easily good enough for three adults to slot across, though the roof-mounted middle seatbelt is a bit annoying. There are air-vents with fan controls mounted in the B-pillars, and the front seat-backs have clever flip-down tables with lighting, and there are mesh map pockets below. There is another 12-volt outlet, a pair of slim door pockets (not big enough for bottles), but no cupholders.

The front cabin is better sorted for storage of odds and ends - there is a pair of (small, shallow) cupholders between the seats, an enormous central console box that’s easily copious enough for phones, wallets, keys and the like, plus another storage area near where you plug in your USB/auxiliary device. The way the owners manual/logbook slots under the steering wheel is neat, and the glove box is fine, too, plus there are reasonably good sized door pockets, but again they lack sculpted bottle holsters.

One little issue I had was with the steering adjustment toggle - it’s quite springy… so much so that it sprung back and hurt my finger every time I adjusted it. That mightn’t be an issue if you’re the sole driver, but it’s worth noting.

As striking as the lovely leather trim is, the dashboard design is what I love most about this car. There’s a huge 12.0-inch high-definition top screen that shows you an enormous digital speed readout, plus you can have it show you the mapping and sat nav, or the car’s vital measures, or see where your car is positioned by way of the standard-fit 360-degree camera.

The lower 7.0-inch touchscreen is where the action happens: it’s your point of control for the media system, including Apple CarPlay and Android Auto smartphone mirroring, the dual-zone climate controls, car settings, and phone. There are supplementary volume and track controls, plus the steering wheel has things sorted pretty well in terms of ergonomics, too.

Okay, to clarify: I love this set up to a degree. I don’t like that the air conditioning controls (apart from de-mist for front and rear windscreens) are all within the lower screen, which means - on a really hot day, for instance - you have to fumble through menus and tap the screen repeatedly, rather than just turn a dial or two. Every sweaty second counts when it’s 40-degrees-plus outside.

One thing Mazda has significantly changed for the ND is the multimedia screen, now a larger 8.8-inch touchscreen running Mazda’s updated software.

It brings the MX-5 up to date without sacrificing simplicity and makes it a little easier to use. The physical dial and buttons for controlling the screen also remain. The USB-C ports are also new.

Oh, and the MX-5 is the first Mazda model to get Connected Services, which is coming to other Mazda models eventually.

Connected Services allows owners to find, lock, and get alerts for their cars from a phone app, even letting them set curfews to notify them if the car is started during certain hours.

Aside from that, another small tweak is the simplified instrument cluster, which aims to be easier to read even when the roof is open and the sun is bright.

The cabin isn’t built to be plush, it’s built for ‘Jinba Ittai’, Mazda’s philosophy that applies most strongly to the MX-5 which means ‘horse and rider as one’.

And trust me, you feel one with the horse- er, car, when there’s not ample room to move. It’s not restrictive, but it’s cosy. 

Everything’s quite well-placed and it’s not busy with buttons or features in here though, it’s made for focusing on driving. 

One downside is the lack of storage, not even a glovebox, in front of the passenger, and the central storage spot under where your elbow sits is tiny, good for keeping the key fob snug though. Also, the cupholders are able to be removed or swapped between the space behind your elbow, or above the passenger footwell.

There’s also a small storage space between the seats behind where your elbow would sit, though it’s tricky to access while you’re driving.

Then there’s the boot, which is usable for a small amount of luggage at 130 litres in the Roadster and 127L in the RF hardtop.

Finally, as a huge positive, probably the biggest advantage of the ND over any other convertible is how easy it is to open and close the roof in the Roadster. You can do it single-handed, which is great if it starts raining and you’re at a traffic light or able to quickly pull over.

The RF hard-top has a switch that automatically opens and closes the roof section.

Getting into an MX-5 is now a little more expensive, with the base manual Roadster up by $2310 to now start from $41,520 before on-roads.

The top-spec soft-top GT RS is now $51,640, or $2800 more than before.

Pricing for the RF hard top is also similarly bumped up, a base manual costing $46,250, and the most expensive GT RS at $56,140.

There’s also a Black Roof edition which comes with tan Nappa leather inside, but that’s only available in an automatic RF, which is possibly the biggest downside to the 2024 range.

Base models get cloth seats, while GT and GT RS models get heated leather seats. The GT RS also comes with stiffer Bilstein dampers, Brembo front brakes, a bracing strut between the front suspension towers and a DSC-Track mode. The difference there is noticeable, so it's worth the extra spend for the more keen driver.

The higher overall costs bring updated tech, a new 8.8-inch touchscreen and a new limited slip-diff in manual versions, plus tweaked mechanicals like improved acceleration response and lower steering rack friction.

But they do look a tiny bit different too.

Under the bonnet is a 1.6-litre petrol four-cylinder turbo unit producing 121kW of power (at 6000rpm) and 240Nm of torque (at a low 1400rpm). If you think about what other seven-seat people-movers have, that’s only okay - for instance, the cheaper LDV G10 people mover has 165kW/330Nm.

The Citroen may have a smaller engine capacity and outputs, but it’s also quite light - it weighs 1505kg (kerb weight) because it’s so small. The LDV, by contrast, weighs 2057kg. In short, it punches at, but not really beyond, its weight.

The Grand C4 Picasso is front-wheel drive, and uses a six-speed automatic transmission with a manual mode and paddle-shifters… yes, that seems unnecessary. The shifter is up on the steering column, which is an ingenious use of space, but the fact it has a dedicated manual mode means you may often choose M rather than D, particularly if you’re in a hurry.

If you plan to do a lot of towing, this isn’t the car for you. The claimed towing capacity is 600 kilograms for a trailer without brakes, or just 800kg for a braked trailer. The diesel is a better bet if that matters to you, with a 750kg un-braked/1300kg braked rating… though that’s still below average compared to some similarly priced petrol seven-seat SUVs like the Mitsubishi Outlander (750kg/1600kg), LDV D90 (750kg/2000kg) or Nissan X-Trail (750kg/1500kg).

Up front, you get one option: a 2.0-litre naturally aspirated four-pot. It makes 135kW and 205Nm, and it’s a delightful little thing, driving the rear wheels only - as it should.

It used to be that the smaller 1.5-litre engine was the more revvy, keen option, rest its soul, but Mazda updated the 2.0-litre to be more eager (and deliver more power) at high revs and basically made the little 1.5-litre redundant.

Anyway, you can have it with a six-speed manual in any variant, or a six-speed automatic in GT guise if you find manual gearboxes difficult or a hassle.

The claimed fuel use for the Grand C4 Picasso petrol model is just 6.4 litres per 100 kilometres, which is rather impressive. It requires 95RON premium unleaded, meaning the cost at the pump can be markedly higher than regular 91RON. 

In the real world, a lot of turbocharged cars tend to be thirstier than the claim suggests, but we saw a relatively decent 8.6L/100km during our time in the Grand C4 Picasso. 

By comparison, the diesel is said to use a miserly 4.5L (17-inch wheels) or 4.6L (18s). 

Let’s do some maths: the average cost per 1000km, based on claimed fuel usage, works out to $65 for the diesel and $102 for the petrol, and you’ll get about 40 per cent more distance per tank out of the diesel, and typically diesel is cheaper. But even so, the extra $6000 outlay on the initial purchase of the diesel will still take plenty of mileage before you break even.

Mazda says the MX-5 uses 6.8L/100km as a manual Roadster, or 7.0L/100km with an automatic gearbox. Or, in the heavier RF 6.9L for a manual and 7.2L for auto.

Not great for a tiny car like this, but pretty good for a sports car!

It’s got a 45-litre fuel tank, takes premium 95 RON or higher, and while it should hypothetically be able to travel more than 600km with its on-paper claims, expect fuel use to sit closer to 8.0L/100km if you’re driving it anything like it deserves.

I’ve mentioned the word ‘charm’ already in this review, and the adjective to describe what I think about the drive experience is ‘charming’.

I love it.

It has that French suspension set-up that just doesn’t get bothered by sharp bumps because it has been tuned to deal with cobblestone alleyways. It rides beautifully at high and low speeds, loping over speed humps with ease, cosseting those in the cabin from the surface below.

It’s also tremendously quiet, with hardly any road noise intrusion in the cabin compared to the vast majority of cars out there. The coarse-chip surfaces of the M4 in Western Sydney usually offer up an ear-bashing, but not here.

The 1.6-litre engine is perky enough.

The steering is like that of a hatchback, with a tight (10.8m) turning circle enabling you to pivot on yourself more readily than you might think. The steering is also quite enjoyable if you like to drive, but don’t push too hard - understeer is an imminent threat, though the grip on offer is quite good.

The 1.6-litre engine is perky enough, and responds well both in stop-start traffic and on the highway - but there is no doubt about it, the 2.0-litre turbo diesel model’s 370Nm of torque makes for motoring with a lot less effort and strain. Not that the engine in the petrol model feels like it can’t get the job done - it just feels like it could do with a little more pulling power… Again, not enough to rule it out of contention, because it’s nicely refined. 

The six-speed automatic is geared towards efficiency, which means that you might find it in third gear before a hill and somewhat hesitant to drop back a gear to gather more pace. I didn’t find this too annoying, but it did help me finally understand why the manual shift and paddles are fitted.  

On the whole, there is a lot to like about this: it’s a family-focused car with family-focused dynamics on all fronts. 

It feels like every motoring journo under the sun (literally if the roof is off) owns or has owned an MX-5 of some sort.

And the first time you drive one, you might understand why. 

If you spend your days testing and driving a bunch of different cars that aim to be many things at once, it’s refreshing to drive something that aims to be one: fun.

That’s it, the MX-5 feels like it was built to be fun. Not for convenience, not for power, certainly not for the school run.

And fortunately its simplicity remains with this update. All Mazda has done to change the way it drives is attempt to improve the rear limited-slip differential and improve the steering a little by reducing friction in the rack, as well as improve throttle response.

Has any of that changed the way it feels to drive on-road? No, not massively, but the ND was already such a delight that Mazda could have kept this update to purely design and interior tech changes and it would have still been one of the best-value buys around in terms of fun.

The MX-5 still feels relatively softly sprung while still being a dynamic and communicative sports car that’s engaging to drive even at low speeds, and rewarding (or frustrating) to drive fast.

On tight, winding roads, the MX-5 is at home, its soft suspension keeps you humble with its shifting weight and its relatively meagre outputs keep your licence safe.

In fact, despite being slightly compromised as a daily drive, the MX-5 is still plenty of fun even in traffic, there’s something about the satisfying click as the shifter slips into gear, or the little rev matches heading back down through the cogs when approaching a red light.

The 2.0-litre four-pot is a keen unit, and the six-speed manual is light and easy to work with, plus its steering is light without sacrificing road surface feedback - that feedback can quickly turn into cabin noise on a coarse highway which could become a little irritating on a long trip.

But the MX-5 can still be plenty of fun on track, where you’re more likely to get the most out of its new limited-slip differential and Track DSC mode.

It’s equally frustrating and satisfying to hustle the MX-5 around the East Circuit at The Bend in South Australia, where the track is twisty, busy, and unforgiving. Get it wrong, and the MX-5 lurches or slides to let you know you’ve made an error. 

Get it right, however, and the little roadster glides through the corners, camber changes and even over apex kerbs smoothly and carrying impressive speed.

Plus, the electronic assistance won’t usually kick-in until you really need it, a welcome change from cars that are constantly trying to keep you from having fun behind the wheel.

The ND MX-5 actually scored five stars with ANCAP back in 2016, even though its score has now expired. It’s not obvious how well it would fare under newer, stricter tests, given the small car’s lack of advanced driver assistance - not that that’s a bad thing in the case of a sports car.

Still, for a two-seat convertible, the MX-5 has a decent list of kit to keep you safe including front and side airbags, alerts for driver attention, blind spots, lane departure and rear-cross traffic, parking sensors and a reversing camera, belt pretensioners and side-impact door beams and even automatic Smart City Brake Support.

Citroen has just updated its ownership promise to consumers, with passenger vehicles attracting a five-year/unlimited kilometre warranty plan, which is backed by a five-year/unlimited kilometre roadside assist package. 

Previously, the plan was three years/100,000km - and that’s even what some of the paperwork on the company’s site still suggests. We assure you, though, the five-year deal is legit.

Servicing is due every 12 months or 20,000km, whichever occurs first, under the Citroen Confidence Service Price Promise plan. The costs for the first three services are $414 (first service), $775 (second service) and $414 (third). That cost cover spans nine years/180,000km.

Mazda’s five-year, unlimited km warranty covers the MX-5, including five years of roadside assist.

Servicing costs are pre-set, with intervals every 12 months or 15,000km up to seven years or 105,000km. They cost between $447 and $638, averaging out at about $544 each.
