Citroen C5X vs Lexus Rx450H+

What's the difference?

This is a new take on the Citroen station wagon, and it’s an impressive one at that. It may not tick all the boxes, but it is a comfortable and practical car, with stunning design, decent equipment and a pretty agreeable price tag.

Now, just get that plug-in hybrid version in at a reasonable price please, Citroen.

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

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

Citroen reckons the C5 X combines SUV, wagon and sedan design cues to make it a true crossover model. I reckon they’ve got a point, and while it’s certainly not as butch as some other crossover wagons out there, it’s not bashful, either.

I’m a massive fan of the assertive front end lighting design, the bold body lines that punctuate the bonnet and swoop backwards down the sides of the car, and the swooping roofline that dips away, almost like the iconic Citroen DS.

It’s quite a large car, too - at 4805mm long on a 2785mm wheelbase, it has a commanding presence, and it’s 1865mm wide (not including the side mirrors) and a rather sleek 1490mm tall. 

Of course it has some body cladding and black plastics to give that ‘rough and tumble’ appearance - and the rear features a couple of spoilers on the boot that help it cut through the air cleanly, and they look interesting as well.

Inside, there’s an almost-square steering wheel, which is interesting, and a pair of screens - a 12.0-inch touchscreen for your multimedia duties, and a 7.0-inch driver info screen. It looks and feels upmarket and pretty conventional in the cabin, so let’s see what the practicality is like.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

The Citroen C5 X is almost as big as a Subaru Outback, and similar in size to a Kia Stinger. So it ought to have a bit of family-friendliness packed in.

Starting at the back, there’s a 545-litre boot capacity, with the kick-action, electronically controlled tailgate that you can also use the keyfob to open. It is a low, wide, quite squared-off aperture, meaning loading bulky items in should be a breeze. Just note that the roofline does taper down towards the rear, so bigger things will need to be pushed towards the seat backrests.

Or, if you’re really acting like a delivery van, you can drop the rear seats down to allow 1640 litres of cargo capacity. There are boot-mounted releases to drop the seats down, and there’s a floor mat in the boot, under which is a space saver spare wheel.

Back seat occupants are decently catered for. I’m 182cm/6’0” tall and I managed to sit behind my own driving position with plenty of leg and foot room - however, the sunroof does create a bit of a hump in the ceiling that you might bump your head on, and those with big feet or small children might want to take note that the sills in the door openings are very tall. A child could easily trip over them if they were clambering in the back in a rush.

Children will be covered with a pair of ISOFIX child-seat anchor points in the window seats and three top-tether restraints, too. There are map pockets, door pockets with bottle holders, a pair of USB-C charge points and directional air vents, too.

However, it wouldn’t be a French car without some kind of quirky cup holder situation, and the back seat has none - there’s no flip-down armrest to speak of. But the seat is exceptionally cushy.

Front seat impressions are good - and cup holders are present. They’re big ones, too - large enough for a big cuppa or a bottle of water, even, And there are door pockets with bottle holsters as well.

There’s an opening centre armrest box with a USB-C charge point, and in front of the interestingly designed recessed gear selector and parking brake, there’s another storage spot with a wireless phone charger, too. Nice.

Seat comfort up front is very good, with lots of adjustability (eight-way electric for the driver, six-way electric for front passenger) and heated front seats as well.

Scoring a big tick from me is the fact there are physical dials and buttons for the air conditioning and ventilation controls. But they’re in that glossy black finish, which shows fingerprints so much that it makes you feel self-conscious of being a walking germ farm.

The big touchscreen multimedia system has a few buttons and knobs, too - though the menus on screen do take some getting used to. It is highly customisable, so if you bought one you’d set it and forget it, but on first impression I struggled to get to grips with some of the nuances of the menus.

It does, however, have wireless or wired Apple CarPlay and Android Auto (with the media-feed USB-C port under the controls) and it goes full screen, too, while leaving enough space for other crucial elements. The graphics are nice and high-definition, and the 360-degree camera display puts  the “surround” view units in Peugeot models to shame. 

There’s also a configurable driver info screen, and a crisp and lovely head-up display as well. 

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.

That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).

The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.

Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.

Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.

There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.

Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.

Yes it’s almost 2023, but the Citroen C5 X model launching right now isn’t bringing anything new or exciting to the table in terms of what’s powering it.

Instead, it runs a 1.6-litre turbo-petrol four-cylinder engine that is also used in other Citroen and Peugeot models. No hybrid tech, no electric version yet….  But Citroen has stated it is keen to bring a plug-in hybrid model to the market. Hopefully, it comes soon.

The petrol motor used here is the brand’s PureTech 180 with Stop & Start, and it’s good for 133kW of power at 5500rpm and 250Nm of torque at 1650rpm. This isn’t a small car, but it is relatively light, weighing in at 1439kg (tare mass). 

However, it has a pretty small engine with low outputs for this type of vehicle. For context, the 508 from Peugeot has 165kW and 300Nm.

The C5 X has a standard fit eight-speed automatic transmission, and despite some SUV pretences, it’s a two-wheel drive, with power sent to the ground via the front wheels only.

That much-anticipated plug-in hybrid (or PHEV) uses the same petrol engine but adds an 81kW electric motor to the mix, for a combined output of 168kW of power and 360Nm of torque. Grunty.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

If you see a brand-new Citroen C5 X in the showroom or on the street you’ll note that the sticker on the windscreen shows an official combined cycle figure of 6.0 litres per 100 kilometres. For a petrol engine, that’s impressive.

Now, whether you get near that will be determined by how you drive. Lots of city and urban driving could result in a higher figure - but it does have start-stop tech for the true traffic grind.

On the launch drive, which included a mix of different driving situations, I saw an on-display return of 8.5 litres per 100 on the trip computer.

Fuel tank capacity is 52 litres, meaning a driving range of 866km if you can achieve the official figure, or 611km if you average what I did on the launch drive.

Can’t wait for the plug-in hybrid version of this car; it has claimed efficiency one-fifth of the petrol version launching initially - yep, it sips a claimed 1.2L/100km… but of course that relies on you making sure you actually charge it up and use the 50km of EV driving range it is said to offer. We’ll cover it off in more detail when the vehicle launches locally, likely sometime in 2023.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

If comfort is your main priority when it comes to your new car, then the Citroen C5 X (or any Citroen, really) should suffice.

The brand says that comfort is one of its defining features - a pillar of why Citroen exists, if you will - and as the flagship model in the brand’s lineup, this should represent the ultimate in comfort. 

And it does. 

The seats - with triple-layer foam - play a big part. They’re wider than most seats and, while they don’t hold you in place like the buckets in a sports car, this isn’t a sports car. 

It also has acoustic glass front and rear to help make it feel more serene and ‘cocoon-like’ inside. There’s barely any wind noise, and just a touch of road roar over coarse-chip roads, but it’s far from noisy in the cabin.

Further, it glides along with relative comfort over bumpy sections of road, with the so-called Suspension with Progressive Hydraulic Cushioning all-but eliminating road surface intrusion into the cabin. 

The suspension has hydraulic cushions at the ends of the springs and dampers (but before the bump stops) that are designed to delete the little bumps in the road surface, while also helping lessen the impact of larger imperfections like potholes. And, with the launch being held in Sydney on yet another wet day, the suspension did a spectacular job. 

You can still feel the 19-inch wheels moving around a bit when you sink into a pockmark, but the way it feels from the driver’s seat is very good. I didn’t get to play passenger on this launch drive, but the seat of the pants vibe I got was that all occupants will be cosseted nicely. 

That tendency towards relaxed movement is reflected in the handling of the car, too. It’s not a corner carver. You can engage Sport mode - which adapts the powertrain (engine and transmission calibration and sensitivity) and also the steering weight, if you really want to.

On the engine - it is perky enough in Sport mode and can do the 0-100km/h sprint in 8.1 seconds, according to Citroen.

This powertrain should really be categorised in the ‘comforting’ rather than ‘compelling’ category. It’s not a bad engine - but you can feel the weight of the car is holding it back, and it particularly feels a bit sluggish from a standing start. I also noticed a bit of vibration through the car under full-throttle acceleration, too. 

But honestly, unless you were trying to duck through a gap in traffic, you’re not likely to spend much time with your foot pinned to the boards in this car. 

I love and admire that this isn’t a car designed to be sporty. It isn’t trying to be that. The PHEV version will be more of a driver’s tool, with an adaptive suspension system and more power and torque. But honestly, I’d be happy with the C5 X as it is, because it’s just a lovely car.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

The RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.

Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.

Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.

Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.

The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.

Buy a Citroen and you get a five-year/unlimited-kilometre warranty, as well as five years roadside assist and a five-year capped price servicing plan.

The C5 X isn’t cheap to maintain, with the average service cost sitting at more than $560 - that’s based on service intervals of 12 months/15,000 kilometres. 

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.
