Alfa Romeo Giulietta vs Mercedes-Benz A-Class

What's the difference?

So much right and some things not quite right – the Giulietta has the Alfa Romeo mix of highs and lows which the brand is famous for. There’s no mistaking that this is a unique and sexy looking car, with the practicality of a five-door hatch plus impressive handling and performance.  More heart than head decision here though it seems, but romantic Alfa enthusiasts should adore it.

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.

Alfa Romeo couldn't design a boring car even if it was handed a picture of a Toyota Camry and told to copy it or else. The Giulietta is no exception.

There's the deep 'V' grille shared with the new Giulia sedan and 4C sports cars that make up the current Alfa model line-up. There's the bug-eye headlights with pretty inset LEDs and the chiselled bonnet, a side profile which looks like that of a mini Porsche Cayenne and a cute-but-tough bottom with its elegant taillights and twin exhausts.

The latest update brought a honeycomb mesh grille and a slightly different design to the headlight and LED foglight surrounds. The tail pipes were also given a styling tweak, so too were the alloy wheels.

Despite its coupe looks it's actually a five-door hatch with ‘hidden' handles for the rear doors.

The cabin saw new materials and finishes added. The Veloce had the Alfa Romeo logo stitched into the integrated headrests, shiny sports pedals, and lashings of faux carbon fibre trim on the doors and dash.

You can tell a Veloce from the outside by the red Brembo brake calipers behind the front wheels, 18-inch alloys, its chunkier exhaust tips poking out of the diffuser, red pin-striping to the front and rear bumpers, and the black window surrounds.

Okay, how big or small is it? Here's some dimensions for you. The Guilietta is 4351mm long, 1798mm wide, 1465mm tall and the Veloce with its sports suspension is 9mm lower than the others with 102mm of ground clearance.

Compared to say a Mazda3 hatch the Giulietta is 109mm shorter end-to-end and only 3mm wider. But if you're considering an Giulietta why are you looking at the Mazda3 anyway? That would be sensible - Like comparing Cancer Council hats to top hats.

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.

Beautiful things tend to favour form over function. The Giuletta tries to do both and succeeds…but also fails in places.

Successes first: despite its coupe looks it's actually a five-door hatch with ‘hidden' handles for the rear doors placed up at window level near the C-pillar. So good is the two-door disguise that our photographer climbed into the back seat through the front door.

Rear legroom is a bit tight back there and at 191cm I can sit behind my driving position but I'd hate for me to be sitting behind me because my knees are digging hard into the seat back.

Headroom isn't much chop either and I literally can't sit in the back seat and hold my head high – a combination of that sloping roofline and the optional double sunroof reduces the head space.

A major practicality fail is the lack of storage throughout the cabin.

Ordering drive-thru is possibly out of the question.

My wife's phone kept mysteriously appearing in the footwell every time we left it in the glove box, like there was a tear in the time-space fabric, but then we realised it was slipping through a gap.

There's no centre armrest storage bin in the front – actually there's no centre armrest. There is a pop-up hidey-hole on the dash but with only enough room for a pair of sunglasses.

The two cup holders in the front are small. It's safe to say that unless you have somebody with hands at the ready, ordering drive-thru is possibly out of the question.

Or if you have long arms and can reach the fold down armrest in the back there are two decent sized cup holders along with a small storage space. There are no bottle holders any of the doors, but there is fortunately room for a phone and wallet because there isn't space for them anywhere else.

But wait, the Giulietta is saved from a total storage fail by a large-for-the-class 350-litre boot. That's 70 litres bigger than a Toyota Corolla's and only 14 litres less than the Mazda3.  We could fit the pram, the shopping and the rest of the gear which goes with a military operation such as a trip to the park with a toddler in there.

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.

We’ll get to the major change under the bonnet shortly, but another significant alteration for this latest C 43 is the price.

It now starts at $134,900 (plus on-road costs), which pushes it well above its market rivals, the BMW M340i xDrive and Audi S4, which start at $104,900 and $106,200, respectively.

However, Mercedes has added more technology under the bonnet and loaded the C 43 up with standard equipment, including its '4Matic' all-wheel drive system, adaptive damping, rear-wheel steering and 20-inch alloy wheels.

In terms of creature comforts, the C 43 is well-appointed, with leather upholstery, a head-up display, augmented reality navigation, a panoramic sliding sunroof, and a Burmester 3D surround sound system.

There are two option packages for the C 43. The 'Digital Light Package' costs $2400 and adds Multibeam LED headlights with 'Ultra Range' highbeam, 'Adaptive Highbeam Assist Plus' as well as active light function and cornering light function.

The 'Performance Ergonomics Package' includes AMG Performance front seats, an AMG Performance steering wheel in Nappa leather and microfibre and the 'AMG Track Pace' system for an additional $5200.

The Giulietta Veloce has a 1.75-litre four-cylinder turbo-petrol engine which produce 177kW of power and 340Nm of torque. It's a great engine that lets loose a wonderful scream when pushed hard and the little grunts it makes when it changes gear when driving around normally sound like a giant enjoying his food.

The transmission is a dual-clutch auto which Alfa calls a TCT or twin-clutch transmission. I'm not a fan of them regardless of the brand of car they're in but the Alfa version is better than most of the others in its smoothness at lower speeds and decisiveness.

There's so much potential here for a great driving experience.

What about the Giulietta's reliability over time? This version of the car is less than two months old so we can only comment on what it offers as a brand-new vehicle, but you'll find good context in our used review of the earlier 2011-2014 Giulietta.

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.

Alfa Romeo says you should see your Veloce drink at a rate of 6.8L/100km during combined driving, but the dash showed more than double that during mainly urban driving while  channelling  Enzo Ferrari.

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.

There's so much potential here for a great driving experience such as the accurate and direct steering and great suspension which provides a comfortable ride and great handling, only for all to be let down by turbo lag which kills the responsiveness in the car.

Of the three steering modes: Dynamic, Natural and All Weather, the Dynamic setting was kept on almost always with the other two just feeling too lethargic.

The Giulietta is front-wheel drive and there's a lot of torque being sent to those wheels, but unlike a stack of Alfas in the past there's next to no torque steer. That said, our hill start test on a wet night saw those front wheels scrambling for traction as it accelerated up the slope. Cornering grip from the tyres is excellent, however.

There's some Alfa Romeo ergonomic issues in the cabin we've gotten used to over the years, but just because you're accustomed to something doesn't mean it's okay. For example, the cramped driver's footwell with the brake and accelerator pedals so close that it's easy to hit both at the same time.

Such is the intensity of the spray from both the window washer and the headlight washers it's like you're captaining a fishing trawler that's hit a massive wave at sea.

The indicator and wiper stalks are also so far from the steering wheel rim that they're almost out of reach – I don't think I have small hands, nobody's ever pointed them out or laughed at them.

And speaking of wipers, the Giulietta is obsessed with keeping itself clean. Pull the wiper stalk towards you to clean the windows and such is the intensity of the spray from both the window washer and the headlight washers it's like you're captaining a fishing trawler that's hit a massive wave at sea. Put the car into reverse and the rear wiper starts squirting and washing.

For Christmas I want Alfa to upgrade their media unit or bin it – the UConnect system disconnected my phone without prompting and isn't intuitive to use.

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 C43 gets a comprehensive list of safety equipment that leaves little out. Obviously there are the usual passive safety items, like 10 airbags, including dual-front combined pelvic/thorax airbags and a front centre bag that drops between the front seat passengers to minimise the chances of a head clash.

Also included as standard is autonomous emergency braking front and rear (covering speeds between 7.0-200km/h), adaptive cruise control with active stop/go, a 360-degree parking camera, 'Active Parking Assist', 'Active Lane Keeping Assist', 'Blind Spot Assist' and, of course, anti-lock brakes with 'Brake Assist' and 'Adaptive Brakes' with Hold function and electronic stability control.

Also included are dusk-sensing LED lights, rain-sensing wipers and run-flat tyres with tyre pressure warning.

The C43 also comes equipped with Mercedes’ 'Driving Assistance Package Plus', which adds even more safety gear. This includes 'Active Blind Spot Assist', 'Active Brake Assist with Cross-Traffic Function', 'Active Emergency Stop Assist', 'Active Lane Change Assist', 'Active Lane Keeping Assist', 'Active Steering Assist', and 'Active Stop-and-Go Assist'.

While the C43 hasn’t been specifically crash-tested, the latest C-Class was rated by ANCAP with a five-star score for all models except the upcoming C 63 S E Performance.

The Giulietta is covered by Alfa Romeo's three year/150,000km warranty. Servicing is recommended at 12month/15,000km intervals with a major service every two years. Alfa Romeo doesn't have capped price servicing but there is Mopar Vehicle Protection which customers can purchase with the vehicle for $1995.

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.
