Renault Kadjar vs Mercedes-Benz S-Class

What's the difference?

The Renault Kadjar Intens ticks a lot of the urban boxes. It’s small, which is good for navigating narrow city streets and parking in tight spaces, but it’s also spacious and practical. The Kadjar is fuel efficient for a four-cylinder petrol engine and it has that sophisticated French styling.

The Intens is expensive, though, and unless you absolutely have to have leather seats, a glass roof, and the Bose stereo I’d go for the mid-range Zen grade and save yourself $5K but still have all the same safety tech. That said the Intens has auto parking as standard which is a nice convenience for the city.

Safety could be better. The AEB system doesn’t have pedestrian and cyclist detection, rear cross traffic alert, or reverse emergency braking.

Finally, the dual-clutch automatic and 1.3-litre turbo-petrol engine while a fuel efficient combination, isn’t all that easy to live with and can make driving a less-than-smooth experience. The Nissan Qashqai’s combination of CVT auto and four-cylinder naturally aspirated engine is better suited to the urban jungle - something to think about there. 

Now the scores, the Kadjar Intens gets the same mark for daily driving and its urban talents – it could be smoother to drive, but there’s still lots to like. 

Mercedes-Benz set out to restore the S-Class' place amongst the greatest sedans in the world.

In the heavily-optioned, near-$250K-plus S450 as well as the extended S450L at $300K as tested (the sweet spot of the range for now), we reckon the Germans have succeeded, pushing safety, comfort and technology boundaries, in a package that is true to the heritage of the series.

Tax-fuelled sky-high prices will certainly keep the S-Class niche in Australia, but the car is more than good enough to dominate its tiny corner of the upper-large luxury car sphere.

The best new car in the world? We reckon it's highly likely. Mission accomplished, Mercedes.

People talk about French design being good. Well if you want to see just how good take a look at the Nissan Qashqai, because the Kadjar is fundamentally the same SUV with Renault’s design spin applied.

Yep, as I mentioned about 15 seconds ago, Renault and Nissan are part of an alliance that allows them to share the same cars, but each brand has room to ‘make it their own’ with styling that delivers a very different look, inside and out.

Now, the Qashqai is not an ugly car, but I think the Kadjar is more stylish and premium looking in the same way the larger Renault Koleos SUV is gorgeous compared to the relatively straight-laced Nissan X-Trail it’s based on.

There’s no doubt the Kadjar is a Renault thanks to the giant diamond logo on the plunging grille. I like the way the front bumper rises up into the bonnet like it’s all one piece, but I’m not completely sold on the rear of the car which looks a bit like its shirt is tucked into the back of its pants, which makes no sense unless you look at the images.

Still, the tail-lights have a prestige feel and the Kadjar model name spelled out across the tailgate is a confident statement, also adopted recently by other brands such as Volkswagen (T-Cross) and Ford (Puma).  

Telling the Intens apart from the other two grades is fairly easy, it has 19-inch wheels (the others have 17-inch rims), there’s the enormous glass roof, and it also has a chrome effect on the front and rear bumpers, side skirts, and around the fog lights. It’s a more premium look.

That higher-end feel goes into the cabin as well with the Intens’ black leather upholstery and colourful ambient lighting. The touchscreen is tiny, though, and there isn’t a great deal inside that you don’t get in the entry-grade Kadjar’s cabin, which is also almost as stylish.

The Kadjar is classified as a small SUV, which means nothing really when it comes to wondering if it’s going to fit in your garage or in the tiny parking spaces we’re faced with in the city.

So, I’ve mapped it out for you. The Kadjar’s dimensions are, 4449mm long, 2058 mm across (including the wing mirrors), and 1612mm tall. 

Another interesting thing – each B-pillar is adorned with a little French flag. I’m not sure if they're a sign of Gallic national pride or to remind everybody that meets the Kadjar that Renaults are French.

Either way, you don’t see this type of thing on other cars and for many buyers the appeal of a Renault is having a car that’s not like everybody else’s.

Most Mercedes models have followed the Russian Doll-style cookie-cutter styling theme, and the heavy family look continues with the W223.

Still, the flush door handles do add a touch of Tesla-esque modernity, while the elegant silhouette and clean lines are in keeping with the luxury aspirations. Larger in every dimension compared to the old W222, the S450 is some 71mm-longer in wheelbase (3106mm) than before while the LWB's has stretched out by 51mm (3216mm), benefiting proportions as well as interior packaging.

AMG-branded wheels look sporty but – in the S450 at least – they're perhaps a tad too gangster. A set of flush alloys would give it a more-modern and techier appearance, in our opinion.

Overall, however, the S-Class ‘7' possesses the prerequisite richness of design. It isn't as bold and mould-breaking as models like the W116 were back in their day, but the styling is still a success.

By the way, the latest S-Class is the first Mercedes to employ the MRA2 longitudinal platform, which is rich in lightweight steels (50 per cent aluminium), is correspondingly stronger than before but also 60kg lighter.

With a drag co-efficiency rating as low as 0.22Cd on some overseas grades, the W223 is one of the most aerodynamic production vehicles in history.

The Kadjar is a big-small SUV, in that it’s longer than many in the same segment at 4.4m with a wheelbase of more than 2.6m, which means more space inside for people and their stuff.

That said, don’t expect limousine legroom, but at 191cm (6'3") tall, I can sit behind my driving position with my knees only just touching the front seat back, which is pretty darn good for a small SUV.

Making life a bit more comfortable back there, too, are directional air vents, two USB charging ports and a 12V power outlet. There are another two USB ports and a 12V up front, too.

Cabin storage is okay. The door pockets in the back are big enough for a 500ml bottle, while there are larger ones in the front, along with two cupholders and another circular hole, which looks like it’s for coins, if anybody still uses those?

The centre console bin is pretty decent in size and so too is the boot which has a cargo capacity of 408 litres with all seats up and 1478 litres with the second row folded flat.

For the beginning of our day with the S-Class, we were chauffeured from home to a mansion in Kew, a blue-chip Melbourne suburb. Our heavily-optioned S450L featured most of the aforementioned extras – including the Business Class Package and Rear Entertainment Package – and the experience was predictably, sumptuously memorable.

Reclining individual rear seats with easy-reach tablets, armrests offering access to all multimedia and available climatised and massaging cushions and backrests... we're no longer in our normal ride, Toto.

Yet, all these trinkets and gizmos are mere add-ons, that can turn a stretched Caprice into a flash hen's night carriage if enough money and glitz is thrown at it.

No, the new S-Class must impress in an altogether less tangible and more philosophical manner, involving all the senses, and not just what we see, hear and touch. It must appeal beyond the superficial. Otherwise, it is not a large Mercedes-Benz luxury sedan in the classic manner.

This is a Herculean task for the Stuttgart designers and engineers. By and large, though, the Three-Pointed Star has succeeded in achieving something special.

In its perception of peerless quality and engineering, the W223 is striving to move forward and look back simultaneously to the glory days of the seminal W126 (1980-1991). This is through meshing traditional virtues like solidity and quality materials while dazzling its passengers with technology that is still friendly enough to want to enhance your experience.

You can sink into the soft lounge seats, watch the world pass by silently outside and never be aware of the road underneath or the engine ahead. Double glazing, exquisite and aromatic fabrics and materials and lush tactile surfaces work their magic inside the car, while an airtight and aero body, solid platform, air suspension and a muted yet muscular powertrain all do their thing underneath. The atmosphere is special and rarefied. That's what an S-Class needs to be and that's what is happening in our $299,000 (as tested) S450L.

The same more-or-less applies up front, as the same trim, leather, wood and technology surrounds the driver and passenger. The spectre of the car that is surely The Car of the Last Decade – Tesla's Model S – is evident in the portrait touchscreen and sparse, almost wallflower dashboard design and layout. No big imposing architectures here.

Yet, while the American upstart actually takes stuff away, the S-Class packs the cabin with subtle features that – like when the planes stopped flying last year and the birdsong subsequently returned – only become obvious once the cabin's design simplicity clears all the white noise for you to be in a better frame of mind to enjoy them.   

Take the haptic interface, for example, as it is perhaps the best we've experienced; the sense of well-being garnered from the cumulative effects of profound seat comfort (the massaging function was never switched off), cocooning micro climate environmental control, orchestral levels of audio entertainment and the theatre of light and vision performed by the two available screens; it is an automotive experience like no other. And the eye-tracking 3D-effect navigation set within the electronic instrumentation. No need for cinematic glasses to get the effect. The driving position itself, by the way, is also first class.

Room to stretch and grow for sure, and in every direction. But room for improvement? You betcha.

Your tester had a headache after a little while staring at that woozy 3D map. The central vents – four at the front, two in the rear – look and feel cheap, leaving us mentally redesigning them; they are frightfully out of place here; the carryover column-stalk auto lever should have been binned in 2005. And, even though the digital instruments have a number of options, none are elegant enough for the S-Class. That's an especially subjective criticism, clearly, but one that – in the context of classic Mercedes luxury sedan contenders – is justified given how timeless the Bruno Sacco era of Daimler design was. Look him up, kids.

Still, after a couple of hours behind the wheel, with our senses reset to calm, it is obvious that the S-Class cabin is a unique and wonderful place – as it should be at a cool quarter-of-a-million dollars.

Job done.

PS At 550 litres (20L more than before), the boot is massive and luxurious enough to sleep in.

Right now, only two S-Class models are available – the S450 from $240,700 plus on-road costs and the 110mm extended-wheelbase S450L (LWB) for another $24,900 on top. Most buyers overwhelmingly opt for the latter.

Despite what the numbers may suggest, both are powered by a 3.0-litre in-line six-cylinder turbo petrol engine, delivering 270kW of power and 500Nm of torque to all four wheels via a nine-speed torque-converter automatic. Greater choices are coming later, including an all-electric version known as the EQS.

Almost every conceivable safety item is standard on the S-Class, including world-first rear-seat airbags located behind the front seats in the LWB model, taking the surround-airbag count to 10.

You'll also find route-based Speed Adaptation (adhering to the posted speed limits), Evasive Steering Assist (a sophisticated form of crash mitigation), adaptive cruise control with active stop/go, Active Lane Change Assist that automatically moves the car into the lane you indicate to), Mercedes' PreSafe crash-preparation tech that primes all the safety systems for impact, electronic stability program that encapsulates all the active driver-assist tech, Active Emergency Stop Assist, Autonomous Emergency Braking front and rear (including for cyclists and pedestrians), Traffic Sign Assist, Parking Package with Active Parking Assist and 360-degree camera and tyre pressure monitors.

On the equipment front there is the latest iteration of Mercedes' MBUX multimedia system with (another) world-first 3D display, complementing an OLED central display, powered closing doors, leather upholstery, air suspension, leather upholstery, velour floor mats, a multi-beam LED headlight system with adaptive high beams, heated and folding exterior mirrors, heat and noise-insulating acoustic glass for front side windows, dark privacy glass for rear windows, sunroof, roller sunblinds for rear windows, metallic paint and 20-inch AMG alloy wheels on runflat tyres.

Want cutting-edge multimedia? There's MBUX II's augmented reality for navigation and fingerprint scanner, as well as a more natural-speech Mercedes-Me Connect voice activation with global search.

Plus, predictive navigation with live traffic, parked vehicle locator, vehicle tracking, emergency call, maintenance management and tele-diagnostics, digital radio, Burmester 3D surround-sound system with 15 speakers and 710W amplifier, remote door locking/unlocking, geofencing, speed-fencing, valet parking, head-up display, Smart Phone integration with Apple CarPlay/Android Auto, wireless charging, ambient lighting, two-zone climate control, poplar wood trim, electric adjustment for front seats, steering column with memory function, climatised front seats, keyless entry/go with flush-fitting door handles offering hands-free access (including for the electric boot),

Besides the ‘forward facing' airbag for the rear-seat occupants, the S450L also scores electrically adjustable rear seats with memory and automatic rear climate control.

Key options – and the list is massive – include an $8700 Rear Entertainment Package, that brings rear-multimedia access, rear tablets with wireless headsets and rear-seat wireless smart phone charging, an AMG Line pack with a body kit, different alloys and larger front brakes ($6500), Business Class Package that includes aircraft-style reclining rear seating and tray tables ($14,500), Nappa leather ($5000), augmented-reality HUD ($2900), 21-inch wheels ($2000) and four-wheel steering ($2700). There's also a $14,500 Energising Package with contoured seating, heated-everything and massaging seats.

Please keep in mind our test cars featured many such extras. Tick all the boxes and you can add nearly $100,000 to the price of your S-Class.

So, is the S450 good value? Given some of the breakthrough safety and luxury features it offers, it is unique. Too bad the Federal Government's Luxury Car Tax makes them so much more expensive than they need to be.

While the Renault Kadjar and Nissan Qashqai are essentially the same car, they don’t share the same powertrain. The Kadjar has a smaller but more powerful engine – a 1.3-litre turbo-petrol four-cylinder making 117kW/260Nm.

Shifting gears is a seven-speed dual-clutch auto. There’s no manual available, and all Kadjars are front-wheel drive.

Frankly, the Qashqai four cylinder with less grunt and CVT are a smoother combination. The dual-clutch auto and turbo lag means power delivery and acceleration are delayed, while low-speed gear shifts can be jerky.

Where are the V8s?

Right now, the only W223 you can buy is powered by an all-new 2999cc 3.0-litre in-line direct-injection six-cylinder turbo petrol engine dubbed the M256, complete with double overhead cams, an electric compressor intercooler and assistance from a 48-volt mild hybrid system and integrated starter-generator, adding 16kW and 250Nm to the 270kW of power at 6100rpm and 500Nm of torque from 1600-4500rpm.

The 9G-Tronic torque-converter automatic transmission and 4Matic all-wheel drive system combination is a first for the S-Class in Australia.

Top speed is limited to 250km/h, while the 0-100km/h sprint-time takes just 5.1 seconds in both models. Impressive for a two-tonne-plus luxury limo.

Renault says after a combination of open and urban roads the Kadjar will have used 6.3L/100km. In my own testing I measured 6.5L/100km at the fuel pump. That’s outstanding.

With the aid of the mild-hybrid system, the S450 returned a combined average of an impressive 8.2 litres per 100km, which translates to 187 grams of carbon dioxide emissions per kilometre. 95 RON premium unleaded (or higher) is recommended. In the urban run it consumes 11.3L/100km (11.5 for S450L), and just 6.4L/100km (6.5 for S450L) in the extra-urban result.

At 76 litres, the fuel tank will allow a combined average range of about 927km between refills.

Renault’s Kadjar may be a better-looking version of Nissan’s Qashqai, but it doesn’t drive as well. This comes down to the engine and transmission Renault has gone with.

There’s turbo lag with that small four-cylinder and this delay is made more pronounced by a dual-clutch transmission that causes the vehicle to lurch during shifts.

This type of shemozzle is not uncommon, the Ford Puma and Nissan Juke behave in the same way with their similar powertrains.

There’s nothing wrong with them, it’s just that for a car that’s probably going to spend its life mainly in the city, the Kadjar won’t provide the smoothest driving experience.

The Qashqai has a CVT automatic and while these transmission aren’t as sporty feeling as a dual-clutch, they’re smooth and good for easy city driving.

The Kadjar does have a comfortable ride and good handling, so if you’re able to get used to the antics of the engine and transmission there’s more to like than not about the way this Renault drives.

In former times, as the Germans say, a ‘450' on the boot indicated V8 power. In the W116 S-Class era it was one of the world's most evocative badges when ‘SEL' was also attached.

As mentioned earlier, though, it's the M256 3.0-litre turbo-petrol with a 48-volt ‘mild hybrid' electrical system that's doing the driving, to all four wheels. The real V8 W223 will probably surface later this year or in early 2022 with the S580L flagship. Bring it on.

This is not to say that S450 isn't good enough. With that electrified assistance, the blown straight six is smooth and swift off the line and rapid as the auto seamlessly steps up through all nine gears. Because it's so hushed and refined, it doesn't feel 5.1s to 100 clicks quick, but watching the speedo says otherwise – acceleration is assertive and strong right up way past the legal speed limit.

All that's missing is the burbling soundtrack of a classic Benz bent-eight. Oh well. Outstanding economy is a price we're literally willing to pay in lieu.

Even more impressive is the S450's ability to hustle along mountain roads like an overgrown sports sedan.

Now, for Australia, all S-Classes are fitted standard with an adaptive ‘Airmatic' air-suspension set-up, including air springs and self-levelling tech. In Comfort up to 60km/h, the ride height can be raised by 30mm, or lowered by 10mm under the standard 130mm baseline in Sport at any velocity, while in Sport+ it falls another 17mm.

With that in mind, yes, the standard air suspension performs a magnificent job smothering out most surface imperfections around town. Yet its real other party trick is to tighten up the chassis when corners get interesting and Sport mode is selected. Aided by progressively weighted and reassuringly responsive steering, the Mercedes tips into turns with precision and poise, slicing through with virtually no discernible body lean or understeer.

Now, we're not talking a leisurely drive on rural highways here, but Healesville's famous Chum Creek Road, where even a Porsche Cayman would feel like it's had a strenuous dynamic workout. The S-Class can be hurried along with confidence and finesse, displaying outstanding handling and roadholding for a 5.2-metre long limo. And the fact that the ride quality only suffers marginally when the red horns are out is all the more remarkable.

Back in the cut-and-thrust of inner-city peak-hour traffic, the Benz in Comfort mode continued to reveal its driver-orientated yet passenger-focused twin-personalities, zipping in and out of gaps while remaining comfy and composed inside.

Only when parking in tight spots are you truly aware that the W223 is longer than a Mazda CX-9. The optional four-wheel-steering system is claimed to slash the turning circle to A-Class hatchback levels. 10.9 metres is the claim.

The 2021 S-Class never ceases to amaze and delight.

The W223 S-Class has not been crash-tested yet by ANCAP or European affiliate EuroNCAP, so does not have a star rating. However, Mercedes-Benz claims it has striven to create one of the safety vehicles on the planet. Who are we to argue?

Almost every conceivable safety item is standard on the S-Class, including world-first rear-seat airbags located behind the front seats in the LWB model, taking the surround-airbag count to 10.

You'll also find route-based Speed Adaptation (adhering to the posted speed limits), Evasive Steering Assist (a sophisticated form of crash mitigation), adaptive cruise control with active stop/go, Active Lane Change Assist that automatically moves the car into the lane you indicate to), Mercedes' PreSafe crash-preparation tech that primes all the safety systems for impact, electronic stability program that encapsulates all the active driver-assist tech, Active Emergency Stop Assist, Autonomous Emergency Braking front and rear (including for cyclists and pedestrians, at speeds from 7km/h to over 200km/h), Traffic Sign Assist, Parking Package with Active Parking Assist and 360-degree camera and tyre pressure monitors.

The Active Lane Keeping Assist works in a speed range of between 60km/h and 250km/h while Active Steer Assist helps the driver follow the lane at speeds of up to 210km/h.

The Kadjar is covered by Renault’s five-year/unlimited kilometre warranty.

Service intervals are every 12 months or 30,000km and capped at $399 for the first three services, followed by $789 for the fourth then back to $399.

There’s also up to five years roadside assistance, if you service your Kadjar with Renault.

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $800 for the first year, $1200 for the second year and $1400 for the third year, totalling $3400. Alternatively, there is a Service Plan starting at $2700 for the first three years (saving $700 from the normal capped-price service plan), $3600 for four years and $5400 for five years.
