Mercedes-Benz S-Class vs Jaguar XJ

What's the difference?

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.

It might be old and facing German competition bursting with advanced technology, but the XJR is still a car you can buy with heart and head. But mostly your heart. It goes like stink, has a much better interior than the Quattroporte and is more interesting than just about anything this big or this grand.

It's also a better car than the Maserati Quattroporte if you want to get on with the driving yourself and is far prettier than the Porsche Panamera. It's a wonderful thing and even more wonderful that Jaguar continues to build it. Long live that supercharged V8 and the XJ is a great home for it.

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 XJ has a marvellously exaggerated length, with a rear overhang redolent of Jag's sporting coupe and roadster pair of the time of its launch, the XK. There's nothing else in the segment like it, with the three Germans - Mercedes' S-Class, Audi's A8 and BMW's 7 Series - having gone all Hugo Boss and and in the latter two's case, almost shrinking violet. The only credible Japanese alternative, the Lexus LS, looks like a Lexused 7 Series. The XJR is a more emotional car, like Maserati's Quattroporte.

The R adds an aggro grille, 20-inch wheels with low-ish profile tyres, a bootlid spoiler, red brake calipers and vents in the bonnet. Bits and pieces get the black gloss treatment and there are V8 and R badges, as well as a rather large leaper on the bootlid. Capping it all off are four exhausts poking out from the bumper and distinctive vertical taillights.

Inside remains largely unchanged. The cabin is big and luxurious, leather-lined and very, very comfortable. The front air vents have to be modelled on the de Havilland Comet's integrated jet engine intakes and, again, the dash design stays away from the horizontal lines of its obvious competition.

There is probably a bit much chrome for my liking, particularly on the centre console and around the rotary dial shifter, which reflects sunlight into your face during the day.

The lovely 'Riva Hoop' - a band that sweeps from door to door across the top of the dash - is a great touch and remains a defining feature in the cabin. The last update brought an Audi-like digital dashboard, including maps, but it's not nearly as slick as the German. The graphics for the dials are good (and quick) but the maps are a bit so-so.

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.

It might be over five metres long, but the Jag's cabin isn't as gigantic as that might suggest - luckily, if you want space, the XJ L has it. The SWB version is roomy enough, though, just not palatial. You can fit five people, but the big transmission tunnel will limit the size of that fifth.

Front and rear passengers have a pair of cupholders each, with rubber bubbles to help hold smaller cups in tight. The front and rear doors have pockets but aren't really for bottles.

Boot space is a reasonable 520 litres, with a space saver spare under the floor.

As is expected at this level, Jaguar was not mucking about with price or specification - the XJR starts at a mildly terrifying $299,995, which is very close to the rather more tranquil Autobiography long-wheelbase relax-o-mobile.

Standard are 20-inch alloys, a 20-speaker stereo, power everything with three memory positions, four-zone climate control, keyless entry and start, front and rear parking sensors, heated and cooled front and rear seats, sat nav, LED headlights and DRLs, leather everywhere, auto wipers and (LED) headlights, electric boot lid, heated steering wheel and a space saver spare.

The Meridian-branded stereo is an absolute cracker, powered by the improved but still laggy 'InControl Pro' system. Oddly, it's all crammed into an 8.0-inch touchscreen when there is seemingly room for the larger (and better-performing) 10.0-inch screen. The software is far superior than the version that preceded the last update, but the screen is hard to use, as targets are placed right in the corners and are hard to hit.

Apple CarPlay and Android Auto are also absent, and the sat nav is still fairly dopey.

A long list of options are available, some of which should probably be included in the big sticker price - DAB+ ($620), premium paint is a splutter-worthy $2060 (although, to be fair, the vast majority of the 19 colours are free), adaptive cruise with queue assist ($2200), adaptive headlights a further $2620 and 'Parking Assist', which adds side sensors and a front camera, a further $2780. Reverse cross traffic alert, blind spot monitoring and forward collision warning cost yet another $1460. Ouch.

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.

Jaguar's lovely 5.0-litre V8 with supercharger continues under the XJ's long and shapely bonnet, delivering a walloping 404kW and a tyre-shredding 680Nm. The sprint to 100km/h for all 1875kg of XJR is completed in an impressive 4.6 seconds, which was very competitive at the car's launch in 2009.

Power reaches the rear wheels via ZF's eight-speed automatic and you can control it with the tacky plastic paddles on the steering wheel. Oh, and it has stop-start.

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.

The combined cycle figure for the V8 is listed at 11.1L/100km but fully expect to see the 16.1L/100km we got, especially as you try and fail to tyre of the monstrous power delivery and lovely (if muted) V8 roar.

Luckily, even if you're belting it, the 82 litre tank is a generous size and you'll cover a fair amount of ground.

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.

Indecently quick, surprisingly agile and heaps of fun. While the first descriptor applies purely because of its size, the next two shouldn't when you're in command of 5.13 metres of motor vehicle. As with the Audi and now the 7, the Jag has a lot of aluminium to help keep the kilos off and good gracious, it has worked.

The R is based around the short wheelbase version of the XJ for perhaps obvious reasons. Even so, it appears to be the shorter-again XF's because this thing turns in like a demon. No, it won't stay with the dearly-departed XF-R but it does a mighty fine impression of one, just with a better ride quality.

Rear seat passengers should be prepared to feel a lot of wheelslip, especially when in Dynamic mode, as even the fat Pirelli P-Zero's struggle for purchase when the right foot hits the carpet. The V8 rumbles rather than bellows, but the rears cheerfully spin up until the computers and active differential rein things in. Traction control off and you've got a proper tyre-smoker if you're not playing by the rules. Jag's engineers are clearly hooligans at heart.

As always, ZF's eight-speed transmission does an incredible job of marshalling the horses in a rearward direction and when you're not after a bit of sound and light, have achieved a tremendous amount with the damping. When in normal mode, the car glides along, so much so that the lady of the house wasn't so sure it was a sporting sedan.

Once she was apprised of dynamic mode (you have to cycle the button through winter mode first, for some reason), her only complaint was that it was too long and the steering wheel too big for this type of car. I was persuaded of the latter, especially after stepping out of an Audi S3 which has a tiny wheel. Long story short, the XJR is now 'her' car (to be more accurate, the XFR is, but that hasn't arrived yet, so...), as it felt smaller than it was when not parking and she's a sucker for a torquey V8.

The whole XJ range has six airbags, ABS, stability and traction controls, emergency brake assist, reversing camera, three top tethers and two ISOFIX points. The XJ doesn't have an ANCAP safety rating.

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.

Jaguar offers a three year/unlimited kilometre warranty and roadside assist for the same period.

Like the F-Type, XJ owners benefit from three years/100,000km free servicing.
