Bentley Continental vs Mercedes-Benz C43

What's the difference?

It may not come cheap, isn’t ideal for family buyers and will have you visiting the petrol bowser regularly, but it’s still hard not to love the Continental GT.

It’s an over-the-top car in so many ways, from the dramatic styling to the plush and pampering interior to the effortlessly powerful engine, this is a car that is a pleasure to drive 10km or 10,000km.

It’s certainly not cheap, especially if you start diving into the options list, or the even more costly Mulliner program, but price is relative, of course, and for Bentley buyers purchasing one of these cars isn’t about getting a ‘bargain’ but instead it’s about experiencing the finer things in life.

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 most interesting aspect of the third-generation Continental GT design is how similar it looks to the first-generation model launched 20 years ago.

Put the pair side-by-side and you’ll notice the latest model is more refined and features crisper lines and more intricate details, but the overall shape and design themes, such as the grille, headlights, etc, bare a similar family resemblance.

This is a deliberate act from Bentley, choosing an evolutionary styling approach for the Continental GT in the same way Porsche has approached the 911.

As for the specific details of this particular Continental GT S model, there are some key differences between it and the standard GT and GT Azure models that sit beneath it in the range. 

The most notable - even if it is slightly harder to spot on our black test car - is a ‘black pack’ that swaps all the chrome finishes on the exterior to black.

This includes the grille, headlight surrounds, lower bumper grille, window surrounds, door mirror caps and the exhaust tips. The S also adds black sports sills and black-painted alloy wheels.

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.

As mentioned earlier, the Continental GT is a two-door, four-seat grand tourer, but while it’s certainly grand, calling it a four seater may be a stretch.

There are two small seats in the rear that can be used if absolutely necessary but anyone in the back won’t feel like they’re in a luxury car because they’ll be cramped for space - even with the roof down.

You could pop small kids in the back in a pinch (and there is a pair of ISOFIX anchor points) but the Continental GT is hardly a family car.

In fact, the Flying Spur is a four-door sedan built on the same underpinnings as the Continental GT, so Bentley does have family buyers covered.

So, let’s keep our attention on the front seats, which is where you want to be in this grand tourer. The seats are comfortable and offer fantastic support, thanks in large part to 12-way electronic adjustment.

To help you enjoy your convertible with the top down regardless of weather, the seats are heated and available with a vent to blow warm or cool air onto your neck.

The seats are just the start, the whole cabin is a blend of modern technology and classic luxury elements.

There’s the media touchscreen, but there’s also a physical button for most functions, so it’s a busy layout but one that will likely appeal to Bentley’s older clientele.

Our test car was fitted with not only the optional sound system but a rotating display, so you can hide the screen away when you’re not using it.

Overall the build quality and attention-to-detail is exceptional, as you’d expect for a car at this price. And it’s really one of the main reasons you buy a Bentley, because it has a level of luxury and quality above brands like Mercedes-Benz and Porsche.

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.

Bentley is renowned for its big, powerful engines, specifically its unique W12. That’s available in the top-of-the-range Continental GT, but the S model we’re driving is motivated by a 4.0-litre twin-turbo V8.

It may not be what Bentley is famous for, but it’s a fantastic engine in its own right and it’s paired to a well-matched eight-speed automatic transmission and an active all-wheel drive system.

Making a very healthy 404kW and 770Nm it has no trouble getting such a big car moving.

Bentley claims the Continental GT S will run 0-100km/h in just 4.1 seconds, which is very rapid and particularly impressive when you realise this car weighs 2335kg.

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.

If you’re looking for a fuel efficient car or are worried about the price of premium unleaded at your local service station, the Continental GT is not for you.

In an entirely unsurprising way, this two-tonne, twin-turbo V8 luxury car is not a fuel-sipping proposition.

Even the official combined urban/highway cycle is 12.5 litres per 100km, which is thirsty.

But if you’re spending most of your time around town, rather than driving to your country weekender, you’ll probably be looking at returns in the mid to high teens, based on our experience.

We saw an average of 16.7L/100km on the car’s long-term trip computer that included more than 1400km of driving.

Fortunately it has a 90-litre tank, which translates to a theoretical driving range of 720km - as long as you can hit the official claim.

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 a duality to the driving experience of the Continental GT, as it manages to blend its obvious luxury focus with a genuinely dynamic edge that makes it a true grand tourer.

The combination of the powerful engine and air suspension means it possesses a laid back personality and effortless nature around town.

The engine delivers its performance with ease, moving this big car rapidly whenever you put your foot down, so you can jump into gaps in traffic or make a brisk getaway from the lights.

It soaks up all the bumps and imperfections on the road with minimal fuss, too, despite our test car riding on 22-inch wheels, so you feel cosseted inside the plush cabin.

However, if you find yourself on the open road, the Continental GT S is equally at home.

Dial up the ‘Sport’ drive mode and the engine feels more responsive, the steering is more direct and the suspension is more taut but still compliant.

It makes this a really fun car to drive on a fast, sweeping rural road, where you can let the engine stretch its legs.

Because of its size it’s not as enjoyable on a twisty road with lots of changes of direction, though.

But for enjoying an opulent daily commute or a weekend drive in the countryside the Continental GT S is a great companion.

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.

Another surprising feature of the Bentley range is the company’s three-year, unlimited kilometre warranty, which feels surprisingly short in this day and age - especially for a brand that takes pride in its carefully built cars.

There is a 10-year warranty available as an optional extra, but it feels like that should be standard if the company is willing to stand by its products anyway and owners are paying such a premium for their cars upfront. 

The good news is all Bentley models are covered by a five-year servicing plan (intervals are 12 months/16,000km) which is included in the cost of the car.

As you should expect from such a premium brand, the local dealer will arrange to collect and return the car when servicing is required, and a loan car can be arranged if required.

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.
