Renault Captur vs Mercedes-Benz Gls450

What's the difference?

There’s no denying the Captur RS Line is expensive.

But it’s also sophisticated, cultured, comfy, friendly and fun, possessing a quality and capability normally expected – but rarely delivered as roundly – in more premium-branded small SUVs. Seen in this light, the Renault’s value is relative.

Better still, if the price is just too rich for you, there are three cheaper grades offering equal promise. Which is why the charming Captur deserves to succeed in Australia.

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

The original Captur was huge in Europe because it was keenly priced, looked good, drove well (being based on the agile Clio IV supermini sure helped) and was intelligently packaged (offering a sliding rear seat).

It’s no shock, then, that the second-gen version revealed in France during 2019 gently evolved the concept with a broader stance, sharper edges and expanded cabin space as a result of a 20mm longer wheelbase and 110mm of increased body length, improving rear legroom and cargo capacity in the process.

Built on the Renault-Nissan-Mitsubishi Alliance’s CMF-B (Common Module Family, B-segment) platform in Spain and shared with the latest Clio (5) sadly not sold in Australia, it benefits from being stronger and sturdier than before, cutting noise levels inside.

Nearly three years on, Captur II remains a handsome and pleasingly proportioned machine, looking somewhat larger than the CX-3 and Puma, yet still trim and taut enough to avoid seeming too big for urban buyers seeking a compact crossover. Its size fits.

Kudos to Renault Australia importers Ateco Automotive for offering interesting, vibrant colour options.

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

There’s no denying how compact the Captur is inside as well. Again, that French city-car DNA shines through clearly.

Yet that doesn’t mean the cabin is cramped or tight, thanks to packaging that’s very intelligently executed, to the point where it will have you thinking twice about needing a larger SUV.

Additionally, the dashboard's layout and ambience possess a Euro chic that is also reflected in the quality feel of most of the switchgear and controls. Even the hard plasticky bits hidden in the lower regions of the console and doors avoid seeming cheap.

The RS Line’s cloth/artificial leather combo with its red striping and contrasting stitching plays up to the SUV’s athletic ambitions; ambient lighting choices are plentiful; the steering wheel is a chunky three-spoke affair that’s lovely to hold and behold; the paddle shifters are astutely sited; and the overall finish corresponds with the Captur’s lofty positioning.

That said, the dash’s design looks a little mid-to-late-last decade, with the 9.3-inch portrait touchscreen already dated after the Cinemascopic hyperscreens dominating the cabins of the latest Mercedes-Benzes, Havals, electrified Hyundais/Kias and others. Remember, the Renault's already celebrated its third birthday in France.

Yet the colourful multimedia system itself is thankfully fast and glitch-free, with clear and easy to understand functionality. The same applies to the RS Line’s digital instrumentation, which are configurable according to which of the drive settings (default/normal ‘My Sense’, Sport or Eco) are chosen. In this regard, the Captur's dash looks bang up-to-date.

In the RS Line, you sit on cosseting sports seats with just the right amount of bolstering. And while the driver’s side lacks lumbar support (you'll need the cheaper Intens for that), we found no fault after hours sat behind the wheel. Note, however, that the front passenger cushion is fixed up high – perhaps too much so for bouffant hairdos.

Points are regained for the simple and effective ventilation system, heaps of storage alternatives including door pockets that will easily swallow a bottle; the hidden phone charger deftly hidden under the gear selector; multitude of USB ports and ample all-round vision, aided by this grade’s excellent 360-degree camera views.

On the other hand, the multimedia system needs a good old-fashioned volume knob, as relying on tapping a screen is annoying and distracting. What is this? 2013? The gear selector might look flash, but it is infuriatingly fiddly. More on that later in the Drive section.

Furthermore, the chrome-like brightwork on the steering wheel spokes reflect sunlight badly during certain points of the day. The instrumentation’s indicator for which gear ratio is selected in manual mode is way too small and carelessly positioned in the bottom right-hand corner, making it difficult and distracting to read at speed. And two rattles reared their ugly heads: from the driver’s door and hatch.

Access to the rear is tight for longer-legged passengers, but once sat, there is more than sufficient head, knee and leg room sat behind front seats set for 178cm tall occupants. The outboard cushion is shaped for comfort, the (fixed) backrest angle is fine for most riders, and a third person can squeeze in the middle as required. There’s decent vision out and the ambience mirrors the front’s quality. Gloomy the Captur is not.

Absent rear-seat centre armrest, cupholders and overhead grab handles is disappointing, but there are rear vent outlets, access to two USB ports and a 12V outlet, sizeable door storage and map pockets behind both front seats.

Further back, the boot benefits from a low loading lip and wide aperture, revealing a seemingly shallow floor, but it's a fake; the sturdy base can easily be removed or lowered to open up a much deeper load area. Ideal for providing hidden storage.

Compared to the previous Captur, luggage volume grows 81 litres. Boot capacity varies from 422L to 536L taking advantage of the unique sliding back seat, moving forward some 160mm. That's especially handy if your rear occupants are children in capsules or booster seats.

Finally, with the 60/40 rear backrests dropped, that extends to 1275L, bringing some 1.57 metres of flat floor space with it.

In summary, then, the Renault’s interior is a clever class act, and in keeping with the RS Line’s premium aspirations.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

Our Polar White test vehicle, which is the base grade in the three-tiered GLS range, comes standard with a 3.0-litre inline six-cylinder turbocharged diesel engine with 48V mild hybrid technology, nine-speed automatic transmission, permanent all-wheel drive and active air suspension for a list price of $189,100.

This pricing is higher than comparative entry-level grades offered by the two marques which dominate sales leadership in this segment, comprising the BMW X7 xDrive40d M Sport ($179,500) and Lexus LX500d AWD ($158,700).

The GLS450d’s standard features include 22-inch AMG alloy wheels with Continental 325/40 R22 tyres and a collapsible spare, ‘AMG Line’ body styling enhancements, aluminium-look illuminated side-steps with non-slip rubber studs, multi-beam LED headlights and more.

Step inside the keyless interior and you’ll find ‘Hey Mercedes’ voice activation, fingerprint scanner (which memorises individual comfort settings for up to seven users), panoramic sunroof, heat-insulating dark-tinted rear privacy glass and the ‘Premium Plus Package’ that includes heating/cooling for the front seats, heated rear seats, head-up display, separate front/rear climate control zones, heated cupholders and more.

There’s also a concert hall-like Burmester surround sound system controlled by a central touchscreen with digital radio and Apple CarPlay and Android Auto connectivity, plus wireless phone charging, multifunction Nappa leather sports steering wheel and USB ports front and rear.

Driver assistance includes the ‘Parking Package’ (360-degree camera, active parking assist and transparent bonnet), ‘Mirror Package’ (auto-dipping rear-view mirror and electric folding door mirrors with puddle lamp projection of the brand logo) and ‘Driver Assistance Package’ (blind-spot assist, exit warning, speed sign recognition, lane keeping etc) all included as standard equipment.

Of course, Mercedes-Benz offers numerous extra-cost options including a 3500kg towing package plus interior, exterior, suspension and wheel enhancements (including Nappa leather trim) for those who want their GLS with the lot, which can easily push the list price beyond $200K.

Here’s a fun fact.

Below the Captur’s stylish bonnet is a powertrain you’ll find in the least-expensive Mercedes-Benz A-Class, B-Class, CLA, GLA and GLB, as well as the related Nissan Juke and all-new Nissan Qashqai.

Developed as part of an expanded engine family by Nissan nearly 20 years ago now, Renault’s version is dubbed the TCe 155, a Euro 6-rated, 1332cc 1.3-litre direct-injection four-cylinder turbo petrol unit, pumping out 113kW of power at 5500rpm and 270Nm of torque at a low 1800rpm.

Drive is sent to the front wheels via a seven-speed dual-clutch transmission (also found in the other vehicles mentioned above). In the Captur, it features three specific modes – Eco, Normal (called My Sense) and Sport – that change steering, transmission and throttle responses, as well as a set of the aforementioned paddle shifters.

As with all the grades, the RS Line manages the 0-100km/h acceleration time in 8.6 seconds, on the way to a top speed of 202km/h.

Weighing in at a lithe 1267kg, this Captur boasts a power-to-weight ratio of a healthy 89.1kW/tonne.

Now, if you've been underwhelmed by or read negative reviews about this powertrain's refinement and/or performance in the various Mercedes models, Juke or even Renault's own Arkana, then brace yourself. 

All is revealed in the Drive section below.

The GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

For reasons outlined in the Driving section, the Captur’s natural verve and spirit is contagious, especially if you’re up for a bit of fun, and we ended up extending this car’s legs well beyond what most regular small SUVs experience. In other words, we enjoyed caning it.

As a result of this foolhardiness, fuel consumption probably suffered in our enthusiastic hands, yet we still managed a credible 7.5 litres per 100km gleaned at the pump, against the trip computer’s 7.2L/100km readout.

That’s not too far off the official combined average of 6.6L/100km. Urban/Extra Urban numbers are 5.4 and 8.8L/100km respectively, while the carbon dioxide emissions average is 149 grams/kilometre.

However, note that the 48-litre fuel tank needs 95 RON premium unleaded petrol minimum. Expect over 700km between refills based on the official combined average consumption figure.

Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

Has Renault finally broken its dreary automatic transmission curse?

The original Captur (and previous Clio) was fun to drive and comfortable to travel in with the old TCe 90 (0.9L three-cylinder turbo) engine/five-speed manual gearbox combo.

But the old 1.2L four-cylinder auto version with the previous six-speed DCT (dual-clutch transmission, also marketed as EDC for Efficient Dual Clutch) suffered from being slow and laggy selecting gears, when all you wanted was an instant shove forward.

No such ailments afflict the Captur II.

Regardless of the DCT, the 1.3L four-pot turbo is a terrifically muscular performer, stepping off the line quickly and smartly, with barely any hesitation or delay. Perhaps the best we've encountered this side of Porsche's PDK transmission.

Even on hills, it is tuned for linear, jerk-free response, aided by a hill-hold function that eliminates the frustration of rolling backwards on inclines. Crawling in heavy traffic, there is none of the flaring or driveline snatch that the old EDC inflicted. Smooth, swift and sweet acceleration is at last available in a modern auto Renault.

And the news gets better as the roads empty out and open up. Throttle response on the move is strong, with speed building up quickly and smoothly. There’s a deep well of torque to draw upon, helped out by the fast-shifting DCT and good spread of ratios, that keep the engine spinning in the sweet spot. It sounds and feels sporty and alive.

Consequently, we reckon the Captur boasts the best application of this powertrain we’ve yet experienced – even amongst the Mercedes models using a variation of it. If only the otherwise-well-rounded Nissan Juke felt as polished as its Renault cousin.

One gripe, though, is the RS Line's gear fly-by-wire gear shifter, which too often fails to engage when you're in a hurry. You need to be slow and measured when selecting Drive or Reverse. Otherwise you may be left panicking mid U-turn. This is our biggest issue with the Captur.

Otherwise, it's plain sailing for France's diminutive SUV.

The Captur’s punchy performance helps it zip into tight spots effortlessly, assisted by direct yet easy steering that weighs up according to whether you’re in relaxed Eco or Sport mode.

Whichever is chosen, the RS Line’s handling is defined by high levels of confidence and composure that only comes with cars that provide feel and feedback.

This, along with linear steering that’s never nervous at speed, means driving the Captur quickly is a blast. Cornering is clean and precise, with the car naturally getting into an easy, gentle flow that makes driver feel part of the car.

This Renault feels connected to the road in more ways than one – and that’s a real rarity in this type of vehicle. Right up there with the animated Ford Puma, this truly is the Clio of smaller SUVs.

The Captur continues to impress when pushed really hard. Driven along a mountain road, there is some body lean through really fast and tight corners, yet is shines with its excellent roadholding abilities. Likewise, this is one small SUV that seems to relish long highway touring. 

Plus, and despite riding on 18-inch wheels, the Captur’s suspension (struts up front and a torsion beam out back, so nothing special or unusual here) is soft enough to soak up most bumps, especially larger speed humps, yet set up to deliver dynamically. It’s way suppler than you might think looking at the twin yellow Renault Sport diamonds on the steering wheel. We suspect the quality Continental PremiumContact 6 215/55R18 H tyres play a big role in this.

Our only concern is the Captur may be a bit too playful in the dirt. Over gravel at speed, the stability and traction control systems take their time to intervene, though they do eventually take over to gently yet emphatically reel in a wiggly rear end before it begins to slide out of control.

Renault has obviously tuned it this way, and it's frankly heaps better than the abrupt or ill-judged set-ups found in other SUVs (hello, Haval), but a mild adrenalin rush will follow if you're not expecting such... initial looseness.

If you love driving and hate the thought of dull SUVs, the Captur is the one for you.

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

The GLS does not have an ANCAP rating as it’s yet to be tested, but comes standard with a suite of passive and active safety features including nine airbags, auto emergency braking (AEB) with pedestrian detection and junction assist, blind-spot monitoring, traffic sign recognition, head-up display, rear cross-traffic alert, lane-keeping, adaptive cruise control with ‘distance assist’ (autonomously brakes/accelerates in heavy traffic), front/rear parking sensors, 360-degree camera and more.

There’s also two ISOFIX and three top-tether child seat anchorages in the second row, plus two more of each in the third.

Renault offers an industry-standard five-year/unlimited kilometre warranty under its ‘Easy Life Ownership’ program, which also includes five years of capped-price servicing and “service-activated” roadside assistance – as long as you have the work done at a Renault-sanctioned dealership. That's when it is renewed annually.

Service intervals are every 12 months or 30,000km (regardless of make/model, we'd recommend a visit to the garage at half that mileage at the very least, though), and are listed at the time of publishing on the Renault website as costing $399 for the first three and fifth services, and $789 for the fourth (48 months/120,000km).

The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.
