Mercedes-Benz A-Class vs Audi A1

What's the difference?

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

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 has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

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. 

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

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. 

The Audi A1 40 TFSI model is far from affordable if you’re looking at city-sized hatchbacks.

The list price for this model is $46,450 plus on-road costs, and for that you don’t even get leather trim! And heated seats? Optional...

You can option the S-line interior package to get a flat-bottomed steering wheel and leather seat trim, but as standard, even on this top-spec variant, you get cloth seats and a boring old round wheel. 

As tested our A1 40 TFSI was $49,720 before on-roads (making for a circa-$55K drive-away price as you see it), because it had the optional blue paint ($490) and black roof ($890), plus the black exterior styling package ($790) and 18-inch Audi Sport wheels ($1100).

It already has 18-inch wheels as standard, plus the S-line exterior body styling pack with sportier front and rear bumpers, sill trims and a rear spoiler.

Plus there are LED headlights and tail-lights, dual-zone climate control, a 10.25-inch digital dashboard, a 10.1-inch multimedia touchscreen with Android Auto, digital radio, built in sat-nav, built-in Wi-Fi and wireless Apple CarPlay.

That’s in addition to push-button start, keyless entry, 2xUSB ports (USB-A and USB-C) ambient lighting, an auto-dimming rearview mirror, wireless phone charging, front and rear parking sensors, semi-autonomous self parking, auto lights and auto wipers, heated and folding mirrors with kerb-side dipping, and a few safety spec items you’ll find in that section below. 

The biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

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.  

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

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.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

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.

The Audi A1 range scored a five-star ANCAP crash test rating in 2019, and it comes kitted out with some impressive safety tech.

There’s auto emergency braking (AEB) that works up to 250km/h for cars, and up to 65km/h for pedestrians and cyclists. There’s also lane departure warning and lane keeping assistance.

You don’t get adaptive cruise control as standard, even on this expensive top-spec model. You can option it but you shouldn’t have to.

There’s no blind-spot monitoring or rear-cross traffic alert, which mightn’t seem like a big issue for a little car, but you’d be surprised how handy that tech can be when you’re reversing out of a parking space or trying to merge.

And while the previous A1 never came with a reversing camera, the new one does - it has guidance lines displayed on the screen, and there are front and rear parking sensors, too. Very handy for the urban jungle. 

All A1s have six airbags (dual front, front side and full-length curtain). 

The C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.

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.
