Mercedes-AMG C43 (2023) Review
The 2023 Mercedes-AMG C43 4Matic ushers in a new era for the Three-pointed Star’s Affalterbach-based division. Does the C43’s electrified 2.0-litre engine deliver enough on-road thrills to emerge from the shadow of the V6 engine in the previous model?
We like: Responsive powertrain, easy to drive quickly, fit and finish, interior wow factor

Where does the 2023 Mercedes-AMG C43 fit in?
Most European manufacturers plan to phase out ICE-powered models by the middle of the next decade (or soon thereafter), but that doesn’t mean many legacy carmakers are in a hurry to ditch their traditional models. The W206-generation Mercedes-Benz C-Class is one of the most important models for the Three-pointed Star and its South African subsidiary; the model (including its Mercedes-AMG derivatives) is manufactured in East London in the Eastern Cape, both for export markets and local consumption.
As things stand, the 2023 Mercedes-AMG C43 4Matic is the fastest, most powerful C-Class available locally, well, at least before the mighty 500-kW C63 S E Performance arrives. Of course, if you must have an SUV, we’re confident that both the 43 and 63 hybrid powertrains will make their way into the GLC.
If you’re looking for a new business-class sedan with standout styling and compelling performance (but want to spend less than the R2-million that the BMW M3 competition M xDrive demands), the Mercedes-AMG C43 competes with a quartet of models. Between just over R1 million and R1.6 million, Alfa Romeo offers the Giulia 2.0T Veloce, Audi the S4 and RS5 Sportback quattros and BMW the M340i xDrive.
Whereas the Giulia is, um, beautiful and sufficiently engaging to drive, the 206-kW 2.0T Veloce (R1 086 900) is not in the same league as the ‘Benz, performance-wise. The Audi S4 costs about the same as its Italian rival, but has 260 kW on tap and its claimed 0-100 kph time (4.7 sec) is just a tenth off the C43’s.
But the Mercedes-AMG’s fiercest competition comes from the 285-kW BMW M340i xDrive with its sonorous inline-6, which is said to bolt from 0 to 100 kph in 4.3 sec, plus its asking price undercuts that of the ‘Benz by more than R300k. The Audi RS5 Sportback, in turn, is a bit of a performance bargain; it costs fractionally less than its rival from Affalterbach and, with 331 kW/600 Nm courtesy of its twin-turbo 2.9-litre V6, it is said to dispatch the 0-100 kph sprint in just under 4 seconds (May 2023 prices quoted).

How the Mercedes-AMG C43 fares in terms of…
Performance and Efficiency
Under the bonnet of the 2023 Mercedes-AMG C43, you’ll find a 2.0-litre 4-cylinder turbopetrol engine –but this one has an ace up its sleeve. You see, this Three-pointed Star motor is electrified and its mild-hybrid configuration is said to enhance efficiency, reduce turbo lag, as well as produce a 10-kW power boost. Outputs of 300 kW and 500 Nm are quoted, with all four wheels propelling the vehicle forward.
New for this 2023 model is a Race Start function, which is even easier to engage than before… Simply turn the drive-mode selection knob to S+, plant your left foot on the brake, flatten the accelerator pedal and the car will be primed to catapult towards the horizon. It’s quite an experience; the C43’s seatbelts suddenly tighten, the dashboard graphics flash dramatically and the cabin fills with engine noise, which is admittedly augmented through the speakers. Then release the brake – the C43 shoots off the line.
Mercedes-AMG claims a 4.6-sec 0-to-100 kph time and our test gear registered a 4.64-sec run. Now before you all run to your social media to ask about the M340i xDrive’s time, we can confirm that the BMW took 4.27 seconds to bolt from 0 to 100 kph when we tested it, so it’s first blood to the Bavarian brand. The C43’s in-gear shove is also particularly impressive; just down gear once (by flicking the left shift paddle), then flex your right foot and the C43 will thrust ahead thanks to its “lag-free” turbo setup.
Comparisons with the previous C43’s glorious-sounding 287 kW/520 Nm 3.0-litre V6 are inevitable and, not everyone has welcomed ‘Benz’s decision to utilise only 4-pot engines in its W206-gen C-Class. Petrolheads may struggle to fathom the presence of a small-capacity mild-hybrid engine in a Mercedes-AMG model, but then again, how many prospective buyers would be in the privileged position to have driven both cars to make a direct comparison between the old and new powerplants? A reckon very few.
The lack of an evocative engine note did bother some of our testers, but others said that the C43’s soundtrack reminded them of a “spicier A45 S”. We do feel a tad sorry for Affalterbach’s engineers; mechanically, there’s not much you can do to a road-going 2.0 litre to make it sound exciting – it’s one of the reasons the dual-clutch gearbox brrupph (known in Golf GTI fan circles as vrr-pah!) was invented! Speaking of the transmission, it emits some lovely thuds and bangs when you change cogs manually.
We were particularly impressed with the vehicle’s powertrain customisation. You can tweak a plethora of the C43’s powertrain and suspension settings to your heart’s content, and our test unit came equipped with Mercedes-AMG TrackPace onboard telemetry, which will probably represent information overload for most consumers. For us car nerds, however, well, we lapped it all up and loved the interface.
Of course, one simply cannot drive with the engine, transmission and suspension tuned to their most aggressive settings ALL THE TIME. Most of the time, a car of this nature will be driven on the commute in its default Comfort drive mode. Once you’ve had your fun, simply turn the dial back to C for Comfort.
When you do that, the power delivery becomes much more subdued, the adaptive dampers soften up and things became way more relaxed. The engine sound is completely dialled back too, but if you need to get a move on, the car will still jump to action if you stand on the loud pedal, just without the theatrics.
Gripes? Well, if we’re being blunt, it all feels a tad artificial, even contrived. We get that downsizing has resulted in a reduction of visceral appeal; Mercedes-AMG has tried to compensate with synthesised sounds and flashy graphics. Would it be a dealbreaker for the C43’s target market? Probably not.
In Comfort mode, progress can be a bit jerky at lower speeds/when driving in congested traffic. The transmission mapping seems a bit dim-witted (it’s almost as if the C43 is befuddled by its own start/stop system, which can be switched off). Things improve if you activate manual mode on the ‘box, however.
We weren’t able to achieve an indicated average fuel consumption figure of under 13.2 L/100 km, but we spent quite a bit of time driving the C43 in its sportiest settings (and testing the derivative’s performance potential). Over time, when the ‘Benz is driven more sedately, that figure should improve considerably.
Ride and Handling
The 2023 Mercedes-AMG C43 incorporates a number of enhancements designed to improve its handling prowess, such as rear-wheel steering and specific tuning for the 4Matic all-wheel-drive system.
The former not only reduces the C43’s turning circle at low speeds, but is said to optimise the sedan’s cornering ability at headier velocities. Can you feel its effect? At speed, not really, but rear-wheel steering is certainly useful when you have to manoeuvre the ‘Benz in and out of tight parking bays.
When we drove on one of our favourite stretches of serpentine tarmac on a particularly gloomy day, we activated S+ and piloted the C43 with considerable zeal. The feeling of sure-footedness and grip galore was immediate, and the car felt neutral and balanced. The 4Matic is set to a fixed rearward bias (31:69) and while we weren’t brave (or foolish) enough to coax the C43 into a tailslide, we could feel the rear end “hint” at wiggling loose as we accelerated hard out of corners, but at no point did it feel unmanageable.
As far as the C43’s steering setup is concerned, it’s adequately sharp, but not the most communicative of its kind… You’re likely to find yourself making tiny micro-adjustments to ensure you can still feel what the car’s front end is doing. It’s a pity, as the rest of the handling package is well-sorted, well, enough to satisfy most drivers. Enthusiasts and driving pros may feel that it’s not quite engaging enough, however.
Again, once you’re done trying to find your personal driving-, as well as the car’s limits, the Mercedes-AMG effortlessly reverts to being a classy high-end luxury sedan. This latest iteration of the C-Class represents a huge step up for both the product and the brand; the W206-gen feels substantially more upmarket than its predecessor – cheap-feeling cabin plastics, a stiff ride and iffy build quality are gone.
Our test unit rode on the standard 19-inch alloys (wrapped in 245/40 tyres) and we think they strike a great balance between comfort, sportiness and style. You can specify 20-inch units at extra cost.
Design and Packaging
In an effort to distinguish the 2023 Mercedes-AMG C43 from its standard C200 and C220d siblings, ‘Benz has adorned this derivative with the Panamericana grille, a quad-exhaust system, a rear diffuser and a neat boot-lid spoiler. There are AMG and subtle “Turbo Electrified” badges on the ‘Benz’s flanks.
Like most modern Mercedes-Benz models, the C43’s elegantly finished and technologically advanced cabin makes a strong first impression. That large infotainment touchscreen, the array of buttons on the multi-spoke steering wheel and the diffuse ambient lighting (at night) takes some time to get used to.
While it looks good, it’s a trifle overwhelming. There are myriad menus and sub-menus to explore, and quite a bit of redundancy (multiple ways to access the same function). The capacitive touchpads on the ‘wheel are a bit fiddly, which is not a C43-specific issue, but a motoring industry problem in general.
Meanwhile, the AMG-branded sports seats (with heating) are a treat. Not only do they look the part, they offer a nice balance between support and comfort. The red seatbelts (a no-cost option) look racy too.
Rear occupant space is acceptable too, although taller passengers may find their heads mashed into the roof lining. You may also find that you sit a bit awkwardly on the rear bench… Perhaps the cushion is a bit too flat and/or short to suit tall adult occupants; one tester said that they seemed to slouch in the seat.
Comfort and Features
At this price point (just over R1.6 million, before options), business-class sedans are expected to come generously equipped and, in the C43, you’re well covered in terms of kit. What’s more, Mercedes-Benz SA has looked to simplify its lengthy options list by grouping extra-cost features into logical packages.
In the C43, you get the Advanced Plus package as standard – it incorporates nice-to-have features such as the expanded MBUX interface, Apple Carplay/Android Auto compatibility, a wireless charging pad, heated and electrically adjustable seats, automatic parking and auto high beam (to name but a few).
For R49 800, you can opt for the Premium package, which adds keyless go, matrix-style digital lights, and a 360-degree camera. The Premium Plus package (R123 500) has all of the above, plus the high-end Burmester 3D audio, head-up display and panoramic sunroof – our test unit came fitted with this.
Some other options include the AMG TrackPace (R5 100), AMG Real Performance Sound (R12 000) and, if want to nudge the top speed up to 265 kph, tick the box called the AMG Driver’s Package (R39 000).
Price and After-Sales Support
The 2023 Mercedes-AMG C43 4Matic retails for R1 625 660 (May 2023) and comes with a PremiumDrive 5-year/100 000 km maintenance plan included.
Verdict
When news broke that the 2023 Mercedes-AMG C43 4Matic would be powered by a downsized engine, some motoring enthusiasts grumbled. It appeared as if Benz’s performance division, which is renowned for its roaring large-capacity engines, had finally caved to pressure from EU policymakers. The arrival of a C43 test unit was not hugely anticipated; in truth, we thought it would be a little underwhelming.
In an effort to make everyone forget about the old C43’s lovely V6, Mercedes-AMG packed the new C43 with an oodles of tech, big screens, multiple modes and artificial sounds. No, it’s not perfect, but when you’re piloting the ‘Benz on a twisty road (with a sporty drive mode engaged), it does deliver satisfaction.
We were impressed by the newcomer’s willing and responsive powertrain, as well as the wide range of adjustability that the electronic interface offers (you can truly set up the car to your liking). For (well-heeled) prospective buyers, this would be a luxury daily driver that offers a healthy dose of sportiness.
The ‘Benz is certainly better than we expected it’d be. Perhaps if the C43 offered more punch and engagement, it may have drawn attention from the imminent 500 kW/1 020 Nm C63 S E Performance…
And that in itself might be the C43’s biggest drawback; it feels more like a spicy C-Class derivative than a Mercedes-AMG model. It’s notably pricier than the BMW M340i xDrive, which has a more evocative 3.0-litre inline-6 turbopetrol engine (with a bit less power, but identical torque) and costs about the same as an RS5 Sportback quattro. The Audi, with its muscular twin-turbo 2.9-litre V6, appeals to performance enthusiasts, even if its cabin can’t match the C43’s technologically advanced and glamorous interior.
It can be argued, however, that the C43 is not aimed at driving enthusiasts per se. It’s tailored for luxury car buyers that appreciate a sporty kerb presence allied with in-car and on-road sophistication – those to whom its sufficiently sizeable performance envelope is a mere bonus. In that regard, it fits the bill.
