Lexus RC F vs Citroen C5X

What's the difference?

There’s so much to like about the Lexus RC F EP3. A glorious atmo V8 soundtrack, sharp dynamics, plus loads of standard features and safety tech in a beautifully engineered four-seat coupe package. It can’t match the turbos for mid-range thump, and if you need practicality look elsewhere, but it’s the type of performance car we’ll be looking back at in years to come as one of the last to proudly hold its head above a rising tide of turbos, hybrids, and electric hot rods. 

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.

At just over 4.7m long, a bit more than 2.0m wide and less than 1.4m high, the RC F has a classically macho wide coupe stance with a distinctive Lexus twist. 

In a late 2019 refresh the RC F was upgraded with suitably jagged single-piece, LED headlights and an even wider version of Lexus’ signature ‘spindle grille’ featuring a new mesh pattern.

Pumped up guards sitting over the standard 19-inch BBS rims feature gills behind them to help smooth airflow around the front of the car, stabilise it overall, and exhaust cooling air flowing around the brakes.

A revised rear diffuser is now body coloured, the stacked-at-an-angle quad exhaust pipes are a Lexus ‘F’ hallmark, stainless steel window trims are now dark rather than bright thanks to a thicker oxide film covering, and the LED tail-lights feature a new L-shaped insert.

Of course, a car’s looks are always subjective, but I think the RC F’s interior is super cool, combining long, flowing graphics on the seats and doors, with rounded, multi-level sections and brushed metal finishes across the dashboard.

The racy instrument binnacle tips its hat to classic sports cars of the ‘60s, the analogue clock between the central air vents could come off as cheesy, but actually looks great, and the large multimedia screen set ‘rear-of-stage’ at the top of the dash is subtly integrated.

True to form, this Lexus is beautifully finished with an obvious eye to design detail and manufacturing quality. Which makes its biggest failing all the more irritating. 

The ‘Remote Touch’ control pad behind the gearshift in the centre console managing settings in the media system is hateful.

Operating in similar fashion to a laptop mousepad (only worse) despite available adjustments for speed/sensitivity, even on its most benign setting it is maddeningly over-reactive and inaccurate. Lexus should just put its hand up, say “My bad” and retire it, yesterday.

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.

Practicality is unlikely to be high on the priority list for anyone shopping for a car like this, but comfort and convenience certainly will be.

And the RC F delivers just that for its front seat passengers, providing lots of space, as well as numerous storage options, including long door bins with room for smaller bottles, two cupholders in the centre console, a large, lidded storage box/armrest between the seats (housing twin USB-A ports, an aux-in jack, and a 12V socket), as well as a decent glove box.

But that space we were just talking about pretty much evaporates when you move to the back. This is a classic ‘2+2.’ The electric folding and sliding front seats make access okay, however, sitting behind the driver’s seat, set for my 183cm height, headroom is tragic, legroom is tight, and toe room is bad. 

So, let’s assume it’s a kids-only area, and once ensconced back there, they’ll appreciate a fold down centre armrest, two cupholders between the seats (with a roll-top cover), and adjustable air vents. But there isn’t a USB point in sight which may lead to friction when devices lose charge, or a plug-in negotiation with front-seaters. 

Lexus claims a modest boot volume of 366 litres (VDA) and it’s important to note that although there’s a ‘ski-port’ door to accommodate lengthy things (like skis?) the rear seats don't fold down. So, flexibility is limited, although there are tie-down hooks at each corner of the floor to help secure tricky loads.

The Lexus RC F is a no-tow zone, and don’t bother looking for a spare of any description, a repair/inflator kit is your only immediate option. Good thing roadside assistance is included in the warranty package.

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. 

Citroen has made it simple for customers. There’s only one spec available for the C5 X at the time of launch, and it comes pretty much fully loaded for the list price of $57,670 (that’s before on-road costs).

The so-called C5 X Shine is the version we get at that price point, though there may be a higher-priced model with a plug-in hybrid powertrain sometime in the near future. 

As it stands, this crossover wagon could be something you consider as an alternative to high-spec Subaru Outback (which maxes out at $55,990 for the new top-spec turbo XT version), or maybe you could think of it as a bit of a cut-price Euro alternative to an Audi A4 Allroad (from $75,200). The Citroen also looks like good value alongside the Peugeot 508 Sportswagon (from $65,657), which it shares a platform and technology with, and a value alternative to a VW Arteon Shooting Brake 140TSI at $65,640.

Standard are 19-inch wheels, LED headlights and daytime running lights, LED tail-lights, LED fog-lights, roof bars, two-tone paint finish with a black roof, leather interior trim, electric front seat adjustment, heated front seats, a sunroof, keyless entry and start, and sat nav with a standard three-year online subscription so your maps will stay up to date. You can extend up to six years, or you can use the integrated Apple CarPlay or Android Auto.

The screens are a 12.0-inch touchscreen for multimedia, and there’s a 7.0-inch driver information screen and a head-up display as well. There are four USB-C ports (two front, two rear), an auto-dimming rearview mirror, front and rear floor mats, and a space saver spare wheel.

The colour palette includes the following colours: Magnetic Blue metallic is the only no-cost paint option, while Steel Grey, Platinum Grey, Amazonite Grey and Nera Black are all priced at $690. Believe it or not, Pearl White paint is the most expensive option at $1050.

It certainly has plenty of gear for the money, and the design is something you’d pay money for, too. Let’s take a closer look at it. 

The Lexus RC F is powered by the latest iteration of the brand’s (2UR-GSE) 5.0-litre, naturally aspirated V8 engine.

Featuring exotic touches such as a dual variable valve timing (with electric actuation on the inlet side), dual-length intake runners, forged connecting rods, titanium valves, and the ‘D-4S’ control system (combining port and direct-fuel injection) it produces 351kW (471hp) at 7100rpm, and 530Nm from 4800-5600rpm.

Drive goes to the rear wheels via an eight-speed (torque converter) automatic transmission with a new ‘AI-Shift’ control designed to adapt to the driver’s style and shift drive modes more effectively, as well as a Torsen mechanical limited-slip differential.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 11.1L/100km, the V8 emitting 254g/km of CO2 in the process.

In our week with the car, over a combination of city, suburban and freeway conditions (including some enthusiastic B-road running) we recorded an average of 12.8L/100km, which, while not exactly frugal, is still impressive for a V8, performance-focused coupe. 

Minimum fuel requirement is 98 RON premium unleaded, and you’ll need 66 litres of it to fill the tank.

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.

A performance car should excite the senses, but the RC-F leans on one a little harder than the rest… hearing.

With the addition of launch control in last year’s update the big V8 will reliably slingshot you from 0-100km/h in just 4.5sec, which is no mucking around quick. But it’s the combination of raucous induction noise, furious mechanical roar, and bellowing titanium exhaust that add extra drama to the experience.

Fact is though, while maximum torque of 530Nm is not to be sneezed at, that number is only available from 4800-5600rpm. Although the RCF starts to get into its stride at about 3000rpm, the twin-turbo BMW M2 CS smashes it for mid-range punch with its 550Nm on tap from just 2350rpm.

So, in everyday, even mildly enthusiastic driving, the RC F sounds amazing, and don’t get me wrong, this is a proper performance car, but it doesn’t have the low-down, kick-in-the-pants grunt of its turbocharged six and eight cylinder competitors.

Linear power delivery, and the crisp throttle response only a naturally aspirated engine can deliver go some way to evening things up, however, and there are multiple systems to help tune the drive experience to your exact preference.

‘Drive Mode Select’ offers five settings (Eco, Normal, Sport S, Sport S+, and Custom).

Eco lowers engine output, dampens the throttle, and dulls the air-con in the name of fuel efficiency and reduced emissions. But you’re not buying this car to save the planet, so don’t touch that button, Sport S is the sweet spot (and save Sport S+ for track days).

Quick gearshifts from the eight-speed auto (particularly using the wheel-mounted paddles), that rapid throttle response, and nice steering feel work seamlessly together to deliver a satisfying backroad experience. Sport S holds gears longer on the way up the ratios, and is quicker to shift on the way back down.

In a more civilised mode, with eight gears to play with, freeway cruising is relaxed, especially given the top two ratios are overdriven.

The ‘Adaptive Variable Suspension’ offers Normal and Sport S modes, and here normal is the go. The basic set-up is double wishbone front, multi-link rear, and Lexus says the SACHS-developed AVS shocks can adjust damping force across a range of 30 levels. But even in the default Normal setting the ride is firm.

According to Lexus, the standard Michelin Pilot Sport 4S tyres (255/35 fr / 275/35 rr) have been tailored specifically to the RC F and they grip hard, keeping the 1715kg coupe planted in quick corners. But their narrow profile no doubt contributes to the car’s less than limo-like feel around town.

Then the ‘Vehicle Dynamic Integrated Management’ system fine tunes the car’s stability control in Sport S+ and Expert modes. Expert only happens when you’re in Sport S+ and turn the stability control off. So again, best to go full racer at the circuit, and we didn’t explore VDIM this time around.

The electrically-assisted steering is not only accurate (the strength of the steering rack bushing has been increased by 150 per cent to boost response), but the wheel itself feels great, and the huge (380mm) Brembo carbon ceramic brakes are mega (working well from cold unlike some other carbon set-ups).  

Under the heading of notable mentions, the digital instrument cluster is inspired by the V10-powered Lexus LFA supercar, switching between a blue economy indicator ring in Eco mode, a standard tachometer and digital speedometer in Normal, a white and red cluster in Sport S, and orange in SPORT S+ (with three-stage upshift indicator lights).

Plus, you can also switch between racy functions such as a lap timer and G-force display, and soft-trim knee pads on the sides of the front centre console improve comfort and seating stability if you’re having a crack.

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.

There’s nothing groundbreaking on offer in terms of safety tech in the C5 X - but it does debut a few things for the Citroen brand, like rear cross-traffic alert. Yep, it took this long to get that in a Citroen.

There’s also active lane positioning assistance, “extended range” blind-spot monitoring and adaptive cruise control with speed sign adjustment, and the expected items like auto emergency braking (AEB) with pedestrian and cyclist detection. 

It has parking sensors front and rear, and a 360 degree view camera. The camera is a big, big step up on the Peugeot 508 that the Citroen shares plenty with.

However, the C5 X doesn’t have a front centre airbag like some new rivals, though it does have dual front, side and curtain airbags fitted. 

There is no ANCAP rating or Euro NCAP score for this car. But based on the current expectations and criteria, it wouldn’t likely score the maximum five-star rating due to some safety technology items being absent (junction assist for AEB, child presence detection, motorcycle AEB). 

The standard Lexus warranty in Australia is four years/100,000km, which outscores the likes of Audi and BMW on duration (both at three years) but trails on kilometres (both offering unlimited km).

Then there’s Merc, which has gazumped all the luxury players with five year/unlimited km cover. Plus, there’s the fact that the mainstream market standard is now five years/unlimited km, with some at seven years.

To balance the scales, the ‘Lexus Encore Privileges’ program provides 24-hour roadside assistance for the duration of the warranty, as well as access to owner events and special offers.

Service is scheduled for 12 months/15,000km (whichever comes first), and Encore capped price servicing is available for a three year period, averaging $595 annually, for an all-in cost of $1785.

A Lexus loan car is provided while your pride and joy is in the workshop, or a pick-up and return option (from home or office) is available in some instances. You’ll also receive a complimentary wash and interior vacuum. Nice.

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.
