Audi A1 vs Mercedes-Benz S-Class

What's the difference?

If you’re eager for a sporty compact hatchback with premium design and luxury car badges, the Audi A1 40 TFSI is a very, very strong contender. It’s fast, fun, and functional for a little hatchback. It’s just very expensive, and for most people the $10K cheaper 35 TFSI model will tick most of the boxes. I’d recommend you drive it before signing on for the top-spec model.

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.

I don’t think I’ve seen a better transformation between generations than the current A1. In its previous guise it was bubbly and cute, but now it’s an angular brute.

This version’s S line sports body kit and funky 18-inch alloy wheels certainly help in that regard, but even the standard lighting signatures - LEDs front and rear - make it stand out as anything but a cutie pie city car.

The good news is that it hasn’t grown too much, either. Sure, it is a bit bigger, measuring 4029mm (on a 2563mm wheelbase), 1740mm wide and 1409mm tall. The last one was smaller (3973mm long on a 2469mm wheelbase, 1746mm wide and 1422mm tall), but this one isn’t elephantine in its proportions and so remains simple to park and squeezy enough to be considered a Light Car by industry standards.

And there are some really, really playful colours available. Like this Turbo Blue (which is only for this spec), and Python Yellow. There’s also black, green, red, three different greys, and two whites. The only issue is that flat white (Cortina White) is the only no-cost paint option. The rest will set out back $490 (for Tioman Green or the blue you see here) or $990 (for the rest). 

And then you can option the paint with a black roof, for $1380 combined with blue or green, or $1880 in all the other colours. The black exterior styling pack adds black highlights around the grille and on the front and rear bumpers. Those little Audi four-ring stickers on the rear doors are standard on this spec.

But to be honest, it stands out no matter what colour you choose, and that’s enough to get people’s heads turning on the street. And the interior design? Well, it has some good and bad points. See the interior pictures below to make up your own mind. 

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.

There are elements of the A1’s cabin design that are tremendous. And other bits that are not so tremendous. 

The bad bits include the fact you’re paying about $50,000 on the road for a car that has hard plastic just about everywhere the eye can see.

The good bits are that the textured plastics on the dash are beautiful, and so are the designed elements on the doors. I love the door handles, I love the metallic finish, I love the layout and I love the way it makes you forget that you’re in a luxury-branded car with hard plastic all around you.

The media screen and digital dashboard help, too - it feels technical and premium in the driver’s seat as a result. The graphics are crisp and clear, the menus are mostly easy to navigate, but I had some issues getting Apple CarPlay to work. It has wireless CarPlay, and I had it plugged in, so perhaps that was confusing things.

But the Audi media system also includes Audi Connect in this spec, meaning there are realtime map, traffic and hazard updates, plus a Wi-Fi hotspot, fuel prices, parking, weather and Google maps and services. It’s high-tech, and if that’s what you like, this is definitely going to please you more than a Mini Cooper.

Practicality is good, with bottle holders in all four doors, cup holders between the front seats and a covered centre console and wireless charging bay in front of the shifter. In the back, storage is sparse: aside from the door pockets, there’s nothing - no cup holders, no map pockets. 

There is enough space for four adults in the A1, so if you plan to take your mates to brunch or if you’ve got young kids, you should be comfortable enough in here.

I had the driver’s seat set for my own height (182cm) and I was able to slide in to the rear seat without much fuss at all, with adequate knee and toe room, and decent headroom too. Try and fit three across the back and it’ll be uncomfortable, unless those three are very slim. 

There are dual ISOFIX child-seat anchor points and three top-tether points, and the seat structure is pretty flat, making fitment of these types of seats simple enough.

The boot capacity is good for a car of this size at 335 litres, which is a solid 20 per cent bigger than before. You won’t find a spare under the boot floor, though, as all A1s have an inflator kit. The back seats fold down to allow 1090L of cargo capacity, but there’s a ledge you have to contend with if you’re trying to load larger items in. Maybe skip the IKEA trips in this one, then. 

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.

This 40 TFSI model is the big humdinger in the range. It has the donk, right?

Yeah, it’s a 2.0-litre four-cylinder turbo-petrol engine, which is a full litre bigger in capacity than the base model car. And it’s the same engine fitted to the Polo GTI - a proper hot hatch!

It doesn’t quite have double the power and torque of the entry-level 30 TFSI model, but it does have solid outputs of 147kW (at 4400-6000rpm) and 320Nm (from 1500-4400rpm). That’s enough to slingshot this A1 from 0-100km/h in a hot-hatch-rivalling 6.5 seconds, according to Audi.

Unlike the lower grades, it runs a six-speed dual-clutch automatic, which it needs because it has so much torque. The 30 and 35 TFSI variants have a seven-speeder. All of them, including this one, are front-wheel drive.

There is no quattro/all-wheel drive A1 this time around, and there won’t be an S1, either. So this is it if you want your kicks in a compact car from the Ingolstadt-based brand.  

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.

Claimed fuel consumption is rated at 6.4 litres per 100 kilometres. You might see close to that on a highway drive, but if you’re primarily city-dwelling like me, then expect higher.

I saw an average of 10.1L/100km during my urban review of the A1 40 TFSI. That was with stop-start engaged the whole time, and the occasional squeeze of the accelerator to test out the claimed acceleration.

Fuel tank size for the A1 is just 40 litres, so if you’re doing what I did with this grade of A1, you can expect to visit the servo every 400km or so.

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.

You shouldn’t be surprised to know that the A1 40 TFSI feels a lot like a Polo GTI to drive. It’s quick, it’s entertaining, it’s refined… it’s just about 50 per cent more expensive.

That mightn’t matter to you or factor into your considerations. I just want to point out that you can get a car that’s just as good to drive as this one, and still with a premium German brand attached to it, for a lot less.

The A1 does have it’s own spunk, though. It has a more masculine character, more aggressive styling, and more delightful interior design.

But it also has steering that is predictable and easy to judge, helping it feel nimble and grippy. From tight twisty roads to roundabouts, you’re going to be having fun in the A1 if you’re tooling around town. 

It feels planted and grippy - aside from some front-wheel spin during take-offs if the tyres are cold - and you might notice the suspension can be a touch noisy as it pitter-patters over inconsistencies in the road surface, but the ride is firm yet controlled, offering enough comfort over potholed city roads and speed humps for this tester. And there are several of each of those obstacles on my daily drive to work.

The engine is a sweetheart, offering brilliant linearity to its power delivery. It pulls hard from low in the rev range, meaning you’ll be able to zip through traffic without much hassle at all. The powertrain is super responsive to inputs at speed, especially if you put it in Dynamic mode, which also allows you to hear some pops and crackles from the exhaust system. 

That said, there is some vibration, shuddering and hesitation at low speeds, which is a combination of the stop-start system kicking in and out, a small amount of turbo-lag from the engine and some shuffling behind the scenes from the dual-clutch transmission. You might find the lurchy nature of the first-gear take-offs to be a bit hard to get used to, especially if you spend a lot of time in bumper-to-bumper traffic. 

While this is an Urban Guide review focused on city driving, I thoroughly recommend you find a quiet stretch of twisty road outside the city limits. You won't be disappointed.

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.

While the VW Polo GTI that this spec of A1 shares plenty with is backed by a five-year/unlimited kilometre warranty plan, the Audi-badged compact hatch still has a lesser three-year/unlimited kay cover. 

The A1 requires servicing every 12 months or 15,000km (just like a Polo), and there’s a pre-pay service pack you can roll into your finance if you so choose.

That service plan covers either three years/45,000km of driving ($1480) or five years/75,000km ($1990). In the case of the five-year plan, Audi is actually better value than the Polo GTI (which costs $2200 for pre-pay). 

Where is the Audi A1 built? You might be surprised to learn the answer is Spain.

Concerned about reliability? Got questions over resale, problems, issues, faults, recalls or something else? Check out our Audi A1 problems page. 

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.
