The Mercedes-Benz AMG C 43 Coupe is an AMG-engineered machine that has been living up to the expectations and has been delivering on every front, without receiving any significant changes. The C 43 borrows the chassis and underpinnings from the more powerful C 63. Looking very sleek and stylish, the car is available as a coupe, convertible, and sedan. The coupe has the distinctive style of the sloping roofline that further adds to the appeal.

Expert Review, Pricing Analysis and Buying Guide

Not many changes are made to the coupe in 2021, but it still stands tall. The engine under the hood of the C 43 Coupe is a 3.0 L V6 mated to a 9-speed automatic transmission. The AMG C 43 Coupe is available in a single trim in an AWD configuration. The C 43 Coupe starts at $60,050 for 2021 and it competes against the likes of the BMW 440i Coupe, Audi S5 Coupe, and Lexus RC 350 F Sport

The 2021 Mercedes-Benz AMG C 43 Coupe comes as a standalone trim starting at $61,050. It comes with a 4MATIC AWD system only and does not feature RWD at all. Also, it only comes with an automatic transmission. There are also additional options you can explore and add to your car. When it comes to packages, perhaps the most important and the one to get would be the Driver Assistance Package for $1,700. 

It features active emergency stop assist, active speed limit assist, DISTRONIC PLUS, active blind spot assist, active lane-keeping assist, active lane change assist, and a host of other useful driver assistance features. Other available Packages include the Multimedia Package, Parking Assistance Package AMG Performance Studio Package, and the AMG Optics package. The following table shows the detailed list of features in the 2021 Mercedes-Benz AMG C 43 Coupe-


AMG C 43 Coupe 



Key Features

18” AMG 5-spoke wheels


Sunroof and power closing trunk lid


10-way heated power-adjustable driver’s seat


Dual-zone automatic climate control 


AMG Performance Sport Nappa leather steering wheel


MB-TEX/DINAMICA upholstery


10.25” COMAND infotainment system


Apple CarPlay and Android Auto


12.3” digital instrument cluster

Turn-by-turn navigation

Which trim should you buy?

We would recommend that you get the car with the Driver Assistance package, as that would make your life a lot easier, while you are driving on the highway during the rush hour. Of course, there is only one model to choose from; but it comes with all the amenities and features and performance you could ask for from a coupe. You can also equip the 19” multispoke matte black wheels for the extra aesthetic. 

Engine and Performance

The 2021 Mercedes-AMG C 43 Coupe comes with a 3.0L bi-turbo V6 that is capable of pumping out a very impressive 385 horsepower and 394 lb-ft of torque. The engine is mated to a 9-speed Speedshift transmission; and power is routed to all four wheels, courtesy of 4MATIC all-wheel drive. The engine is a beast, bearing in mind the pricing and the market position of the car. The transmission used inside Mercs never fails to impress, and here too.

The 9-speed automatic is always quick and offers smooth and seamless gear shifts with easy transitions. The engine will have enough pull for both city and highway driving. The V6 allows the C 43 to jump from 0 to 60 MPH in a mere 4.3 seconds. It can race past the quarter-mile in just 12.6 seconds. Top speed is limited to 130 MPH; but you wouldn’t push your coupe that hard, would you? Even if you do, it can handle that.

The German automobiles are all on the same echelon when it comes to performance, power, and price. The RC has the least power, and that translates to the track as well, where it is the slowest car among the bunch. The German counterparts are just faster. The BMW being the fastest and least expensive among the rivals is the standout performer here. 

How well does the 2021 Mercedes-AMG C 43 Coupe handle?

The C 43 has a handling behavior that is somewhere between the C300 and the AMG C 63. While it is not overly sporty or athletic, it is far from being a boring car to drive. The steering response is good, and the steering is precise and sharp. The 4MATIC system does a very good job of offering that traction and keeping the car planted on the ground. The heft is well balanced and well managed.

The ride quality is firm. It is not the smoothest, but it is also not as harsh as the C 63. The rear suspension setup does a good job of keeping the occupants inside from too much trouble. However, when you go over medium to large-sized potholes or some disturbances on the road, you will feel that jolt. For regular driving, it’s fine and comfortable. It is a good coupe to drive and it is also enjoyable, but don’t expect sports car-like behavior.

2021 Mercedes-Benz AMG C 43 Coupe Braking Performance

The AMG comes with 4-wheel disc brakes with 14.2-inch rotors in the front and 12.6-inch rotors at the back. The brakes are very effective and work very well. The pedal is light, but it might be difficult to modulate at certain times. However, despite that, the brakes are indeed pretty powerful and they make this hefty coupe come to a stop rather quickly. Weighing in at 3902 lbs, it is definitely not the lightest coupe out there, but it still comes to a halt from 60 MPH in just 110 feet.

When it comes to braking, all of the sedans are pretty much excellent. The Merc fits the biggest brakes, and it along with the Bimmer is on the heavier side. All these machines have impressive braking capabilities and they all come to stop from 60mph at a similar distance. It is the Audi S5 Prestige Coupe that leads the braking segment followed by the BMW M440i and the Mercedes-Benz at the last. 

Fuel Economy

The C 43 comes with a rather okay-ish fuel economy. You definitely would not praise it, but you would also not curse it. It falls somewhere in the range of mediocrity with the performance it provides. The EPA estimates are 19 MPG for the city, 27 MPG for the highway, and 22 MPG for combined driving. The car also comes with a gas tank of 17.4-gallons, which means that it has a total range of 330/469/382 miles for city/highway/combined driving. While that is not too bad, you might need to stop more than often for a very long road trip.

Except for the Bimmer, none of the engines are particularly fuel-efficient, but they do their best. The Merc has the largest gas tank, but due to the lower fuel economy, it offers only as much range as the Lexus and not as the BMW M440i. The BMW dominated here as well by delivering the best efficiency figure while also being the fastest. The Bimmer with a comparatively smaller fuel capacity still offers the most range. 


The interior is pretty gorgeous, as you would have guessed. The 2021 Mercedes-AMG C 43 Coupe is laden with lots of features and luxury. The focus is on offering an interior that feels every bit modern as it feels premium. The dash features the classic Merc rounded air vents and the infotainment system sticking out from the center. There are quality materials almost everywhere. It features MB-Tex/Dinamica upholstery, with an MB-Tex leatherette door trim insert and an upholstered dashboard. There is also dual-zone front automatic climate control. A sunroof further illuminates the interior. The AMG Nappa leather performance steering wheel looks and feels premium.

The front seats are 10-way power-adjustable and heated and come with a memory function. They are pretty comfortable and they also feature good bolstering. Of course, being a coupe, the rear seats are not fit for tall adults. Smaller adults and children might somehow squeeze in for a short trip. However, the front row is extremely spacious and luxurious to be at. The rear sloping roofline hurts the headroom of the rear row, but it also affects the cargo storing capacity of the C 43. It offers 10.5 cubic feet of cargo storage, which should be enough for a small weekend trip for two with your golf clubs and all your groceries. The rear seats can be folded in a 40/20/40-split and they increase the area even further for more storage.

The Bimmer offers the most legroom in the rear row, but it still is not enough for a comfortable journey. The Lexus has the most cramped rear row. The front row is extremely spacious in all of the cars. The cargo capacity is also not much in any of these coupes, but the M440i offers a tiny bit more than the others on the list. Key interior features in the 2021 Mercedes-Benz AMG C 43 Coupe are:

  • 14-way power-adjustable and heated front seats
  • MB-Tex/DINAMICA upholstery
  • AMG Performance sport Nappa leather steering wheel
  • Dual-zone front automatic climate control
  • MB-Tex leatherette upholstered dashboard
  • 4-way lumbar support

What’s there to keep you entertained?

Some Mercedes models have moved to the brand new MBUX infotainment system, which is truly amazing. However, this one still comes with a 10.25” COMAND infotainment system, with the screen sticking out from the center. The 12.3” digital instrument cluster is also made standard now. The system is functional and intuitive, but it is definitely not the best. Oh, and it's not a touchscreen. You can control it from the steering-wheel-mounted controls or the center console dial. 

Standard features include Apple CarPlay, Android Auto, Bluetooth, HD radio, SiriusXM Radio, Mercedes ME connect mobile hotspot internet access, and all the other basic features. Optionally, you can equip a Wi-Fi hotspot, navigation, AMG Track Pace, etc. The C 43 also features a 13-speaker Burmester surround sound system. Highlights of the infotainment system in the 2021 Mercedes-Benz AMG C 43 Coupe are:

  • 10.25” COMAND infotainment system
  • 12.3” digital instrument cluster

  • Apple CarPlay and Android Auto

  • 13-speaker Burmester sound system

The Mercedes design is about being classy, grand, and not very outlandish with the style, unlike BMW and Audi. Some people might really prefer the daring design cues that most manufacturers follow, but Mercedes sticks to being lowkey and offering a classic look. That being said, the C 43 does not feature an iconic design, but it surely is subtle and easily recognizable. The LED headlights flank the twin-blade grille with the big round Merc logo in the center. The front bumper looks a little aggressive with curves and angles. 

2021 Mercedes-Benz AMG C 43 Coupe Driving View

The hood of the C 43 Coupe is muscular and the body lines flow from the front wheel fender to the rear, offering a crease that makes the car look aggressive. The sloping roofline will never be boring, but it does hurt the rear seat space and headroom. The rear end features two big LED taillights with quad round-exhaust setups. The C 43 rides on 18” wheels; but you can also upgrade to the 19” AMG 5-spoke wheels. The design is very elegant and simple, rather than being too bold and aggressive.

All the dimensions are quite identical, but the wheelbase of the RC 350 is the smallest, followed by the Audi. All coupes have a distinct taste and every single one looks pretty impressive and attractive in their own way. The weights of these machines are also very similar, but the Merc and BMW are the marginally heavier ones. The Lexus RC 350 F Sport and BMW offer a better ground clearance compared to the Mercedes. Key exterior features of the AMG C 43 include-

  • Quad stainless-steel exhaust
  • Strut front suspension w/ coil springs
  • Multi-link rear suspension w/ coil springs
  • 18” AMG 5-spoke wheels
  • Power heated side mirrors
  • LED DRLs
  • LED brake lights
  • Rear fog lamps

The 2021 Mercedes-AMG C 43 Coupe has not been tested by either NHTSA or IIHS, as it is a little too expensive, perhaps. However, the regular C-Class has been tested and it has flourished in the safety tests. Since the C 43 is also based on the same underpinnings as the C-Class, we can take a look at its safety ratings, and it should translate well over to the C 43 as well. The 2021 C-Class was awarded an impeccable “Good” in all six Crashworthiness tests and was also awarded the Top Safety Pick+ for 2021. The 2020 C-Class, which is essentially the same as the 2021 C-Class, was also awarded a 5-star safety rating by NHTSA. So, the C 43 must also be a pretty safe and worry-free ride. The Merc also comes with a very good list of standard safety and driver assistance features. But you can also add more, thanks to the Driver Assistance package. Key safety features in the 2021 Mercedes-Benz AMG C 43 Coupe are:

  • Crosswind Assist
  • Blindspot assist
  • Active brake assist with autonomous emergency braking
  • Front collision mitigation
  • Front driver monitoring
  • Back-up camera
  • Active emergency stop assist (optional)
  • Active distance assist DISTRONIC (optional)
  • Active blind spot assist (optional)
  • DISTRONIC PLUS w/ steering assist (optional) 

2021 Mercedes-AMG C 43 Coupe vs 2021 BMW M440i Coupe

Both are excellent German machines and both go head-to-head as their eternal rivalry rages on. The BMW M440i is certainly the one that is more economical and offers a tad bit more practicality.

2021 BMW M440i Coupe

It is also quicker and offers an impressive list of standard features. However, that new grille is perhaps the most controversial point of this car; and we are not sure what BMW was thinking. Some people might avoid the car altogether.

2021 Mercedes-AMG C 43 Coupe vs 2021 Audi S5 Coupe

Another excellent German car, the S5 also locks horns with the C 43. The Audi S5 is essentially the same when you compare the specs, with identical performance, interior room, cargo capacity, and fuel economy.

2021 Audi S5 Coupe

It also features a lot of tech and a long list of standard features, like the Merc. The S5 does have a much more stylish and modern look, which would definitely suit someone who prefers outlandish looks.

2021 Mercedes-AMG C 43 Coupe vs 2021 Lexus RC 350 F Sport

The Lexus RC 350 F Sport is not a German car, and it does not compete with the Merc when it comes to performance. It is quite slow, but it offers a very posh interior with a very long list of standard tech and safety features. Perhaps, the infotainment in the Merc is better.

2021 Lexus RC 350 F Sport

The one major advantage the Japanese car has is the pricing. It costs a lot less and it is perfect for someone who loves lots of sharp edges and cuts in their car’s design. The Lexus has the boldest styling among them all, and also that Japanese reliability is a huge factor.

Final Verdict

The Mercedes-Benz AMG C 43 Coupe is definitely not a cheap car, but it exists for a reason. Those who want more than the typical C-Class, but cannot afford the C 63, can enjoy the C 43. It has a lot of power and it is very quick. Not the most fuel-efficient and the most practical, but it has a lot of tech and safety and driver assistance features. Also, it looks elegant and classy, which is perfect if you love subtlety. Consider the other German options, but the 2021 Mercedes-AMG C 43 Coupe is definitely an amazing buy.
