Mercedes-Benz E-Class vs Mercedes-Benz C43

What's the difference?

It's nice to see the E-Class still embody the ancestral heritage of Mercedes-Benz, a brand which has had much change forced upon it in the last decade.

This hybrid one in particular does a remarkable job of blending the future and the past in one deeply capable and customisable package, but not one without its flaws.

While the E 300 e manages to unite these elements nicely, it's ultimately held back by its classic rear-drive underpinnings which have consequences for packaging and electric range.

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.

The E-Class recently received a significant facelift to bring it in line with the brand's latest design ethos, and it serves to refine an already elegant sedan.

The E-Class isn't just the brand's definition by reputation, but by its look, too. While some may be disappointed by how similar it now looks to the C-Class below, or the S-Class above, giving the core Mercedes sedan range near identical silhouettes, it cuts a unique path from its traditional rivals.

BMW's 5 Series leans into a sharper and more aggressive design language, while Audi's A6 does much the same with a post-modernist edge.

I'd argue the stoic Germanic stare of the E-Class’ softer face places the Mercedes exactly where it needs to be, but it doesn't stray from its sporty rear-drive underpinnings entirely.

The car's new blacked-out highlights accentuate its width, and the 10-spoke alloys on our test car fill the wheelarches and draw your eye to the car's low stance and big brakes.

A classic Benz beltline runs from the front lights to the rear, uniting a tidy and clearly well-built package.

Inside and the more luxury-focused touch of the E-Class compared to rivals is evident. Lavish wood trims work their way through the doors and across the grandiose dash, and while the flashy screen fittings from the wider Benz range are present here, the interior is toned down several notches from the glitz of the brand's smaller vehicles.

This offers it a much more stately ambiance, matched by the synthetic leather ‘Artico’ seats which are more like lounge chairs you sink into.

The overall design links the E-Class with its siblings nicely, and there are a lot of the brand's re-imagined classic touches present, like the circular climate vents, wooden panel inserts, and silver-tinged toggles which run down the centre.

It's not all retro, though, with the E-Class wowing observers with its giant single gloss panel hosting the multimedia suite and digital dash elements.

Obviously, you can go further here, with a long list of optional interior colour and trim combinations to customise the E-Class to your heart's content, although I was happy with the classic black on brown woodgrain of our test car.

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.

The E-Class takes many forms around the world, and one of them is a taxicab which makes a lot of sense because the E-Class is one of the few cars I've had on test of late that I'd actually like to be driven around in rather than always take the helm myself.

The rear seat space is enormous behind my own driving position, and the detailed luxurious trims continue, complete with the dazzling milled silver speaker fittings, woodgrain trim, and in our test car, rear heated seats.

Again, the seats are ones you simply sink into, and the window is nice and wide for great visibility.

Alongside rear heated seats in our car, amenities include large bottle holders in the doors, flip-out ones in the armrest, hard shell pockets on the back of the front seats, as well as dual adjustable air vents with a lock-off.

The front seats also offer generous space, comfortable and supportive designs, and a lavish space for full-sized adults with a high level of adjustability.

As much as I hate the fact that you have to tick pricey option boxes on an already pricey car, the amenities they afford are properly luxurious.

The seat heating, for example, extends to the armrests in the doors and centre console, and the third climate zone is a necessary touch if you're ferrying around rear passengers often.

While a sedan like this is never going to have the ease of seating of an SUV, there are lots of little areas where this Benz shines.

Proper four-door keyless entry is a nice touch. As is the ability to pre-condition the cabin, the way the doors open nice and wide, and the 40/20/40 split fold of the rear seats allow you to use the centre fold as a ski-port in European style.

Up front, you can customise the digital dash how you see fit, and while the touch panel controls on the wheel and centre console can be clumsy at times, at least there are multiple ways to interact with the system, and a physical dial for volume control hasn't been forgotten.

Over time I've even warmed to the centrally-located touchpad controller. It's easier to use than the one in Lexus products, and it's nice that I have a way to interact with the piano-gloss screen without needing to reach over to it while I'm concentrating on the road (leaving finger prints all over it in the process).

Even things as simple as the car's instruction manual being entirely digitized into the multimedia suite, complete with search function, is just smart.

The layout of the E-Class creates a significant reduction in boot space in this hybrid version, however.

Because it's a rear-drive sedan, it requires the batteries to be awkwardly packaged under the floor and on top of the axle, so the boot floor is an odd, tiered surface, with space reduced from a decent sedan-sized 540 litres (VDA) in purely petrol variants to a hatchback-sized 370L in this PHEV.

As you might be able to tell from the pictures, this shelf arrangement makes the space hard to use, although it did manage to fit our largest (124L) CarsGuide travel case on an angle.

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 E 300 e has a 2.0-litre turbocharged four-cylinder petrol engine producing 155kW/350Nm mated to a nine-speed torque converter automatic transmission, driving the rear wheels.

The transmission contains an electric motor which is capable of producing 90kW/440Nm on its own, allowing full range of motion in the ‘Electric’ driving mode.

It is also capable of hybrid assistance to the petrol motor, making the E 300 e the fastest non-AMG-badged E-Class model to 100km/h, with a claimed sprint time of just 5.7 seconds.

It also has a 13.5kWh lithium-ion battery pack, which is good for a claimed electric-only driving range of 51km (on the more lenient NEDC testing cycle).

It's a complex mix of gear, and the electric range I experienced was certainly less than 40km. In other words, it's used up very quickly.

The Benz offers some interesting driving modes to help with this, which we'll explore later in this review.

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.

All of this hybrid gear leads to impressive consumption figures. Officially the E 300 e will consume just 2.2L/100km on the combined driving cycle, with around 13.0kWh/100km of energy consumption worked in as part of that calculation.

However, the hybrid Benz requires 98 RON premium fuel, has a smaller tank (60L) than its all-combustion counterparts, and its claimed 51km of NEDC range is more in the late thirties or early forties in the real-world in my experience.

That said, our car consumed a blend of 5.6L/100km and 8.3kWh/100km in my time with it, which is a nice balance of fuel and energy consumption.

I drove it with a lot of electric mode in the mix, but also had a day solely on the engine, and some experimenting with 'Sport' mode and 'Battery Saver' which is designed to maintain the battery level whilst using hybrid mode where it can.

The E300 e accepts a European-standard Type 2 ‘Mennekes’ charging cable in AC form only. It can charge at a theoretical max speed of 7.4kW, although the max I extracted from my local solar-charged AC outlet was 7.2kW.

It took around an hour and a half to get my E 300 e to about two-thirds charge. It would have charged to 100 per cent in around two hours using this method.

Expect somewhere between four and five hours for it to charge to 80 per cent from a 2.4kW wall socket with the included charger.

The system as a whole works well, but I wish it had more purely electric range. A battery closer to 20kWh would offer 60 or 70km of real-world range for a car of this weight, but would eat significantly more boot capacity.

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.

For all the electrification and evolution in Mercedes-Benz’ greater range, it's almost like coming home to sit in the E-Class.

Not only does the E 300 e stay true to the brand's luxury sedan roots with the comfort and refinement on offer, but it's perhaps the one variant in the E-Class range that makes a significant stride toward the future of the nameplate.

I'm sure we'll see a fully electric version of the E-Class in the near future (the brand is shifting to electric-only with an aggressive timeline), but for now, at this price, hybrid is the way forward for luxury sedan refinement.

The way this car blends its electric and combustion modes is notably smooth, and the engine is so distant it's genuinely hard to tell when it turns on, unlike this car's smaller A 250 e PHEV hatch sibling which takes a major drop in refinement when the rattly 1.3-litre four-cylinder engine needs to be relied upon.

This is likely due to the higher-end nature of the 2.0-litre engine and nine speed longitudinally mounted transmission in a much larger and heavier car. One thing I've never liked about the Mercedes PHEVs (and is a common problem among many PHEVs) is the ‘hybrid’ mode could be a bit smoother and more transparent on how it divides its time between electric and with the engine on. At times it runs the engine at the lights for no reason, and it seems unusually keen to turn it on when it could be using electric power. Perhaps we are spoiled by the simplicity and twenty years of refinement of Toyota's Hybrid Synergy drive, but it has the affect of making you wish every hybrid was as good.

The default ‘Comfort’ mode, while the most forgiving in terms of this car's ride, is weighted toward entirely draining the battery before it uses combustion power. The extra drive modes and customisation this PHEV offers are very useful though. Battery Saver mode lets you rely predominantly on combustion power. It's better to use on the freeway where combustion power is at its most efficient, allowing you to switch back to Comfort or Electric when you're stuck in traffic.

Sport hunkers the E-Class down for a sportier and firmer experience, and it also tweaks the accelerator response and auto transmission for a far more aggressive driving tune. As this mode won't use the electric motor at all, even at low speeds, it can be handy to use it to charge the battery via regenerative braking for times when you might not have access to a charger.

In fully electric mode, the regen braking can be tweaked to the max using the paddle shifters to increase your electric efficiency and range.

Like the smaller A 250 e, it's a highly customisable experience, letting you experience as much or as little electrification as you want in the moment, although in this case it's let down a little by the limited battery capacity.

Still, the E 300 e is an E-Class, quieter and sleeker than before. The ride is as stately as the interior suggests, and even on those 19-inch wheels little noise or discomfort makes its way into the plush cabin. The transmission is as close to an old ‘slush-o-matic’ you can get, and I mean that in a good way. Unless you're in one of the Sport modes, it will never interfere with the experience from behind the wheel.

Once you do awaken it in Sport or Sport + though, it shifts, even via paddles, with a surprising urgency, and it's in those modes where the air suspension transforms the cosy barge-like ride from Comfort or Electric into something far more rigid and responsive.

The dynamic breadth of ability in this car is a reminder of what premium money like this can buy. On the one hand you have the luxury of an economical comfort saloon, and on the other you have at least an inkling of semi-electrified performance at the flick of a switch.

Just remember to plug it in when you get home, or you're lugging around a lot of battery for no good reason.

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.

Mercedes covers all its passenger cars with a five year and unlimited kilometre warranty, beating out its primary Audi and BMW rivals which persist with three-year offerings, and generally out-performing the premium segment.

The E-Class needs to be looked at once every 12 months or 25,000km, whichever occurs first, and like many German automakers, service packages can be bundled in at the time of purchase to bring overall costs down.

In the case of the E-Class, this will set you back $2450 for three years, $3200 for four years, or $4800 for five years, at a claimed minimum saving (three years) of $550 compared to paying-as-you go.

It's not as expensive or as unknown as it used to be here, but at close to $1000 per year, even when purchasing via the pre-paid packs, it's still very much at the premium end.

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.
