Mercedes-Benz A-Class vs Volkswagen Polo

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.

The Polo GTI faces tough competition in the form of Hyundai’s recently arrived, very good, and well-equipped i20 N, as well as Ford’s sleek and super-capable Fiesta ST. But as mentioned at the start, VW occupies the hot-hatch high ground with the GTI badge, and this upgraded Polo is loaded with features, dynamically outstanding and on the leading edge in terms of safety. Time will tell if the higher price, higher spec strategy is the right one, but there’s no doubting this updated Polo GTI is a compelling package.

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.

Not exactly a massive change to the exterior of the Polo GTI with this mid-life refresh, but sharp-eyed car spotters will notice a new front bumper treatment including a revised lower grille, defined by a body-coloured border and flanked by LED driving lights.

The headlights have also been reshaped to mark the arrival of standard matrix LED beams, with the signature horizontal red keyline moves from the centre to the bottom edge of the upper grille. A continuous LED strip across the nose stands the car apart after dark.

Previously part of the GTI’s ‘Luxury Pack’, the ‘Faro’ design 18-inch alloys fill the wheel arches nicely, and overall the car’s compact, tightly wrapped body and finely chiselled lines are familiar.

At the back, the LED tail-light clusters have been extended laterally into the hatch door, but the car’s fundamental shape is unchanged. 

Inside the dash layout is the same, although the centre of the sports steering wheel has been massaged into a more organic shape with the airbag/horn now an oval rather than a circle.

The rest of the interior is relatively understated in typical VW fashion, the neatly sculpted sports seats trimmed with traditional ‘Clark’ tartan cloth on the cushion and backrest centres. And ‘Kings Red’ inlays in the dash, centre console and front door trims, are a reminder of the car’s heritage and sporty intent.

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.

At just under 4.1 metres long the Polo GTI is a decidedly compact hot hatch, but thanks in no small part to a relatively lengthy (2.6m) wheelbase, interior space is impressive.

The driver and front passenger have plenty of breathing room, and the rear is remarkable. At 183cm, sitting behind the driver’s seat set to my position, I enjoyed ample legroom, and more than enough headroom.

Width is another story, because while two adults will be fine in the back, there isn’t enough space for three to sit in comfort for any length of time. 

Storage options in the front include a small lidded box between the seats (which doubles as an adjustable armrest), two cupholders and various oddments spaces in the centre console, as well as the wireless charging bay in front of the gearshift. 

There are also pockets in the doors with room for (medium) bottles, a decent glove box, a shallow drawer under the passenger seat, and an overhead drop-down tray for glasses.

Map pockets on the front seat backrests, and small bins in the doors add extra practicality, but there’s no fold-down centre armrest or individual ventilation control for rear seaters. 

For connectivity and power, there are two USB-C ports in the front, plus another two in the rear, as well as a 12-volt socket in the front centre console.

Boot space is a healthy 305 litres (VDA) with the 60/40 split-folding rear seats upright, that number growing to 1079L with them folded down. 

Tie down anchors are handy for strapping loose loads, while shopping bag hooks help keep smaller bundles under control. And be aware, the spare is a space-saver.

Headline news is the Polo GTI’s before on-road costs price has gone up by close to 18 per cent, from $32,890 to $38,750. 

Why? More standard equipment; some new things and other previously optional features now included in the base price.

The aim is to bring the car into line with the specification the majority of customers are ordering, because Volkswagen believes the days of a ‘price leader’ Polo GTI are behind it. That is, pique a buyer’s interest with a keenly priced but relatively sparse base model, and they invariably add options once engaged in the process.

So, the Polo GTI has put a price gap on its two key competitors, the Ford Fiesta ST ($32,290) and Hyundai i20N ($32,990), but it’s now loaded with a whole lot of fruit for the money.

The new bits are ‘Matrix’ LED headlights, a centre airbag, and 18-inch alloy rims (up from 17s), while the elements moved from the options list to the standard equipment column are assistance features bundled under the ‘IQ.Drive’ umbrella including, blind-spot monitoring, rear cross-traffic alert, front parking sensors (joining those in the rear), ‘Park Assist’, adaptive cruise control, and auto-folding exterior mirrors.

Also included in the GTI’s base price are the ‘IQ.Light’ matrix LED headlights, ‘Dynamic Light Assist’ (auto low to main beam switch with light profile adjusted to avoid dazzling cars ahead or oncoming), ‘Premium’ LED tail-lights (with dynamic indicators), metallic paint ($600 on the Polo Life and Style), LED driving lights, dual-zone climate-control, front and rear carpet mats, ‘Digital Cockpit Pro’ (incorporating nav and phone functions), ambient interior lighting, wireless device charging, and sports front seats.

Then you can add ‘Discover’ nav in the 8.0-inch media touchscreen set-up, auto headlights, rain-sensing wipers, ‘Manoeuvre Braking’ (low-speed rear AEB), an auto-dimming rearview mirror, leather trim on the sports steering wheel, gearshift and handbrake lever, and six-speaker audio.

A ‘Sound & Tech Package’ is available for the GTI ($1500) incorporating a 9.2-inch multimedia screen, and a Beats branded premium audio system (digital eight-channel amp, 300 watts).

A Panoramic glass sunroof ($1500) is also offered, and premium metallic paint adds $300.

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.

The Polo GTI is powered by a version of Volkswagen’s 2.0-litre (EA888) four-cylinder turbo-petrol engine, driving the front wheels through a six-speed dual-clutch auto transmission.

The iron block/alloy head unit uses direct- and port-injection, variable valve lift on the intake side, and variable valve timing on the intake and exhaust sides to produce maximum torque of 320Nm from 1450 to 4390rpm, at which point peak power of 147kW takes over from 4390-6000rpm.

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.

VW’s official fuel economy figure for the Polo GTI on the combined (ADR 81/02 - urban, extra-urban) cycle is 6.5L/100km, the 2.0-litre turbo four emitting 150g/km of CO2 in the process. Not bad for hot-hatch with this kind of performance. 

Minimum fuel requirement is 95 RON premium unleaded and you’ll need 40 litres of it to fill the tank. Using the official consumption figure that translates to a range of 615km.

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.

The Polo launch drive program covered around 150km of city, suburban and freeway running from inner Sydney, through twisting B-roads to the city’s south, and sprawling semi-rural areas further west, topped off with a closed track session at the Luddenham Raceway.

Weighing in at a fraction over 1.3 tonnes, with 147kW/320Nm sent to the front wheels, the Polo GTI is capable of sprinting from 0-100km/h in 6.8 seconds, which is satisfyingly quick.

And the 2.0-litre, four-cylinder turbo-petrol engine’s dyno sheet must be a thing of beauty with maximum torque available from from 1450 to 4390rpm, and peak power picking things up at precisely the end of that plateau, remaining on tap all the way to 6000rpm.

So, mid-range punch is always there, and the six-speed ‘DSG’ dual-clutch auto delivers rapid, precise shifts, with wheel-mounted paddles dialling up the fun factor when you want to shift ratios yourself.

Combined engine and exhaust noise is agreeably rorty without tipping over the annoyance threshold, although the high-performance 215/40 Continental ContiSportContact rubber transfers a fair amount of rumble on coarser surfaces.  

The base suspension set-up is strut front/torsion beam rear, with the standard ‘Sport Select’ system built around switchable dampers, offering the choice of ‘Normal’ and ‘Sport’ modes. 

Normal is nicely composed with comfy compliance over longer undulations as well as higher frequency bumps and dips. But if the red mist descends and you’re ready for some fun the (noticeably firmer) Sport setting buttons everything down that bit more. 

As well as the damping, throttle response is faster, the DSG picks up the pace as does the steering. Even the exhaust is enhanced, although it’s via the synthetic ‘Sound Actuator.’ Boo!

Balanced and predictable in quick cornering, the Polo GTI’s electro-mechanically assisted steering is precise and beautifully weighted, with great road feel. And the car’s ‘Extended Differential Lock’ uses the traction control and braking systems to minimise wheel spin, maximise traction, and help limit understeer.

On top of all that, the carefully sculpted sports seats deliver secure location without compromising comfort, and the grippy sports wheel feels great.

Braking is by ventilated discs at the front with solid rotors at the rear, and even under the pressure of a flat-out track session (moderated with the help of some admirably patient tame racing drivers) they remained progressive and firm.

In more civilised surroundings the Polo’s size and excellent all-around vision (not to mention a clear reversing camera) make it a cinch to park. The combination of on-screen touch controls, and physical dials for the multimedia system is welcome. And the connection for Apple CarPlay and Android Auto is wired or wireless which is handy for those who prefer the surety of a wired connection or the flexibility of one less cable in their life.

The current Polo scored a maximum five-star ANCAP rating when it launched in 2018, and it must have been tempting for VW to save more than a few euros by side-stepping active and passive safety upgrades in this refresh.

But, bravo, it didn’t, the German giant re-submitting this updated version for assessment against more challenging 2022 criteria.

The GTI is loaded with a raft of crash-avoidance tech under the umbrella of ‘IQ.Drive’, including AEB (with cyclist and pedestrian detection), lane-keeping assist (with lane departure warning), ‘Multi-Collision Brake’ (automatically slows the car after a collision, reducing the chance of a secondary impact), driver fatigue detection, ‘Park Assist’ (perpendicular and parallel), front and rear parking distance sensors, rear AEB (low-speed), a reversing camera (with static and dynamic guidelines), adaptive cruise control (with speed limiter and distance warning display), and tyre pressure monitoring.

If, despite all that, a crash is unavoidable there are seven airbags on-board - driver and front passenger (front and side), front centre, and full-length side curtain.

A front centre airbag is the solution many manufacturers are using to meet ANCAP’s recently introduced, tougher criteria around head clash injuries. 

There are three top tether points across the rear seat for child seats and/or baby capsules, with ISOFIX anchors on the two outer positions.

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.

Volkswagen Australia covers the Polo GTI with a five-year/unlimited kilometre warranty, which is now the volume market standard.

The paint is warranted for three years/unlimited kilometres, “Through Corrosion” is covered for 12 years/unlimited kilometres, and 12 months roadside assistance is included.

Servicing is required every 12 months or 15,000km, with prices over the first five years ranging from a low of $455 to a high of $1498, the average per service coming out at $701, which is a pretty solid number.

Capped price servicing is available, however, over five- and three-year plans. Paying up-front for five years results in a $765 saving over pay-as-you-go.

A nice side benefit is the ability to fold servicing costs into the vehicle’s financing at the time of purchase, and the plan is transferable if you decide to sell the car before the five or three years is up.
