Mortals have always admired a convertible Mercedes-Benz, particularly when they're wild. The 2021 Mercedes-AMG C63 Convertible pursues a lineage of fast drop-top Mercs, and thanks to years of evolution, it's one of the best performance cabriolets on the road today. 

Its strength comes from a potent twin-turbo 4.0-liter V8 with 469 horsepower to get the C63 to sixty in the low four-second range. But that hardcore performance does require some sacrifice. The C 63 Cabrio isn't a comfortable car – even with the adaptive suspension – nor does this Benz have the latest technology. Cabriolet variants now have Aircap (a retractable wing at the top of the windshield to improve wind deflection) as standard and a semi-automatic trunk separator.

The BMW M4 starts at an equal $78,300, but to buy a Jaguar F-Type that can match these cars’ abilities, you'll have to stretch for the 380-hp supercharged V6 model, which goes for $87,400.

Expert Review, Pricing Analysis and Buying Guide


Overall Rating

While it uses the same mechanical package as its sensible sister sedan, the cabriolet wears far more adventurous clothes. It bears a close resemblance to the flagship Mercedes S-Class Coupe. Mercedes-AMG has done an excellent job of packaging the drop-top C63 in a way that doesn't compromise interior space too much, and as always, the interior feels refined and robust. 

An equally exciting soundtrack accompanies Mercedes' blistering performance. At idle, it burbles away in typical V8 fashion, while extending the revs creates an evocative NASCAR howl.

2021 Mercedes-Benz AMG C 63 Convertible Maintenance, Reliability and Warranty

High running costs are an issue for customers, with expensive servicing being a particular concern. However, Mercedes has attempted to address this by offering flexible servicing plans. The new Mercedes-Benz C-Class also seems to provide great value for the money. 

J.D. Power gives the Mercedes-Benz C-Class a below-average predicted reliability rating of 2.5 out of five. The 2020 Mercedes-Benz C-Class sedan earned ratings of Good in all six tests performed by the Insurance Institute for Highway Safety. It was named a Top Safety Pick+, the organization’s highest honour.

Reliability and Ownership Costs

When buyers want a high-end luxury vehicle, they often turn to Mercedes-Benz. It’s no surprise since they build these vehicles to last a long time and still have plenty of speed to play with. 

According to J.D. Power ratings, the 2020 Mercedes AMG C 63 was rated 80 out of 100, a good rating. The details of the rating are as follows:

  • Quality and reliability: 81 /100
  • Driving experience: 82 /100
  • Resale: 74 /100
  • Dealership Experience: 83 /100

The Mercedes C-Class finished 74th out of 100 cars overall in the CarbuyerDriver Power 2019 customer satisfaction survey. Owners praised its engine performance and in-car technology (sat-nav aside). However, one in five owners reported having an issue with their car, generally with the electrics or brakes.

The C63 certainly feels robustly screwed together, while many of its components are shared with the standard C-Class. And although the 4.0-liter V8 is a complex piece of engineering, it’s already seen service in the AMG GT coupe and, like all units from Mercedes’ high-performance brand, the twin-turbo engine is essentially hand-built to the highest standards.

Pricing for the base C63 starts at the not-inconsiderable sum of $71,390 before a $995 destination and other taxes. The annual maintenance cost of a Mercedes-Benz C63 is $739. Repair and maintenance costs vary depending on age, mileage, location, and shop. Talking about the ownership costs, you will almost have to shell about $52,300 in 5 years after purchasing a brand new Mercedes-AMG C63 series. 


The C63 has an excellent quality and reliability score from J.D. Power, and thus far, is recall-free. However, the identical 2019 model suffers two recalls: one for a potentially faulty active brake assist system and another for a locknut on the steering rack that could fail. Should there be any issues, Mercedes backs its AMG C 63 with:



Limited warranty

4 years/ 50,000 miles; whichever is earlier

Powertrain warranty

4 years/ 50,000 miles; whichever is earlier

24-hour roadside assistance

4 years/ 50,000 miles; whichever is earlier

Rust Warranty

4 years/ 50,000 miles; whichever is earlier

Lexus is a luxury brand, it’s also a division of Toyota. That means parts and labor are cheaper, which makes Lexus maintenance costs cheaper as well. The same goes for Infiniti – Nissan’s line of luxury vehicles. The German automakers cost more to maintain. Then again, these brands also have many die-hard fans who wouldn’t drive anything else.

Miles Per Dollar

Concerning the current state rate of fuel per gallon in the USA is around 2.5 dollars, it can be said that the new Mercedes-AMG C63 runs almost 17 miles per gallon in the city as well 25 miles per gallon on highways. So it can be said that it practically runs 4 to 5 miles per dollar in the city while 6 to 7 miles per dollar on the highway. 

2021 Mercedes-Benz AMG C 63 Convertible Buying Advice

Mercedes-AMG offers a healthy number of optional packages that will see the C63 Convertible's asking price shoot through the roof. We would suggest one with the AMG carbon-fiber interior package and throw in the driver assistance package, which adds active steering assist, active braking assists with cross-traffic function, and active lane-change assist speed-limit assist, and route-based speed adaptation. 

It might also be worthwhile getting an additional maintenance plan, which starts from $1,490 for a two-year/20,000-mile package.

Is buying a used Mercedes-AMG C63 Cabriolet a good idea?

A random fact report says that a used Mercedes almost costs 47% less than the new one. It means you will practically pay $35,000 less if you plan to buy a used Mercedes-AMG C63. They are almost rated average or below average in terms of reliability and have a poor rating on JD power reports in terms of resale value. 

Getting to the bottom line, if you are planning to buy a used Mercedes, it is for sure that you will need to get its repair and maintenance done from time to time. Moreover, if you are planning to buy a used C63 Cabriolet, then 2017, 2016, and 2015 models are enjoying the best value for money services with outstanding reliability.

2021 Mercedes-Benz AMG C 63 Convertible Engine and Performance


Even with some extra heft via the removable cloth top, the C63 still turns on a dime. The 4.0-litre bi-turbo V8 engine had always worked like a monster, well, in this case, it delivers 469 horsepower and 479 lb-ft of torque. Crazy, isn't it? Its throttle response feels perfect, and power is served up in a balancing act of linearity and building a dramatic climax.

2021 Mercedes-Benz AMG C 63 Convertible has 4.0L Biturbo V8 engine

All of the AMG models have an AMG-tuned sport nine-speed automatic transmission. Power and acceleration in these performance trims are exhilarating. You'll be thrown back in your seat when you hit the gas, and each engine features a raucous exhaust note.

Although Mercedes-Benz AMG C 63 has excellent power figures, it still seems less compared to the Chevrolet Camaro Convertible ZL1. Jaguar F-Type R-Dynamic Convertible is the poorest in terms of power generation. The transmission of C 63 is responsive but suits the more laid back personality of the convertible, lacking the quickfire shifts found in the M4.

2021 Mercedes-AMG C63 Cabriolet Acceleration And Braking Performance

Put the drive mode selector to Sport+ (one of four settings, including Comfort, Sport, and Race), prod the gas pedal, and hang on. The C63 S rockets off the line to 60 miles per hour in 3.9 seconds with no lag and no hesitation. Flat out, it'll hit 180 mph – wind in your hair all the while.

Because it’s an AMG, you also benefit from more prominent and more powerful brakes. Braking is another area where the C63 should shine, with appropriate pedal travel and feel allowing you to make consistently calm stops every time.

The 2021 Mercedes-AMG C63 Cabriolet in terms of braking stops from 60 to 0 in only 106 ft. As the C43 has four-wheel drive its towering performance is surprisingly accessible. That makes it a fine choice if you want a swift and smooth acceleration, but which still offers you a chance to have fun on the twisty route home.

2021 Mercedes-Benz AMG C 63 Convertible Fuel Economy


You weren't expecting stellar fuel economy out of a twin-turbocharged V8, were you? The Mercedes-AMG C63  convertible gets 17 miles per gallon city, 24 highway, and 20 combined. And that hand-built V8 does require premium fuel, which hurts its score.

By downsizing the engine from 6.2-liters to 4.0-liters and adopting technology such as stop-start, Mercedes’ engineers have managed to reduce CO2 emissions.

That hand-built V8 does require premium fuel, which hurts its score. But it's not terrible against the competitive set. The ZL1 Convertible is the most massive drinker here with a gas mileage figure of 16 mpg combined.

2021 Mercedes-Benz AMG C 63 Convertible Interior


Despite losing its roof, the Mercedes-AMG C63 Convertible has enough interior space to seat four average-sized adults in comfort. Even in the most comfortable drive mode, the C-Class is harsh, and in any drive mode outside of Comfort, the adaptive suspension borders on back-breaking.

The high-quality Nappa leather buckets, standard on the AMG 63 model, offer good bolstering and great adjustability, and ours wear a neat tuxedo-like Platinum White and black color combo. But the seats aren't super comfy, which only exacerbates the Cabrio’s already harsh ride, and the back seats are tight comparatively.

The C-Class Cabrio’s 32.0 inches of rear legroom is worse than convertible competitors like the BMW M4 (37.1 inches). Mercedes-AMG gives 8.8 cubic feet when the top is up; that's a class-leading amount of space. 

The BMW M4 manages 7.8 cubic feet while the Jaguar F-Type Convertible only gets 7.3. Compact executive convertibles aren't renowned for offering the most impressive levels of trunk and cargo space.

How’s the 2021 Mercedes-AMG C63 Cabriolet’s infotainment system?

The C 63 is heavily influenced by its flagship S-Class limousine and oozes that sort of premium appeal that even Audi and BMW struggle to match. Highlights include the metal-finished ‘eyeball’ air vents, the intuitive rotary controller for the COMAND infotainment system,, and an enhanced 12.3-inch tablet-style screen mounted on top of the dashboard.

There are touchpad controls on the steering wheel, too, which allow you to navigate without taking your hands off the wheel. The infotainment system features an Android Auto, Apple CarPlay, a Wi-Fi hot spot, Bluetooth, two USB ports, HD Radio, and a five-speaker stereo as standard.

2021 Mercedes-Benz AMG C 63 Convertible Exterior


The outlook created by the Mercedes-AMG C63 can be compared to a shark. It is big, bulky, but just when you press the throttle, you will be amazed by the things it can do. One thing in which Mercedes has played well is by increasing the size of the front grill by almost 40%, making it more versatile and more terrifying to look at. Those sharp LED lights, deeper splitters, and the aerodynamic body not only help the car taunch faster but also make it look more fierce and dynamic.

The sides are lower and pressed into the overall chassis well, just as you would expect a luxury convertible to look like. These large 20 inches wheels wrapped around the body add more muscle and sharpness to the overall look. It has also added a rear spoiler, which makes the body more aerodynamic.

Mercedes-AMG is the heaviest in comparison to its rivals. This compact executive performance convertible is on the larger side of things when compared to its rivals the BMW M4 Convertible and Jaguar F-Type Convertible.

2021 Mercedes-Benz AMG C 63 Convertible Safety


Safety is another area where Mercedes has built up an enviable reputation and the C63 does nothing to undermine this tradition. The IIHS and NHTSA have not rated the C63 coupe in their respective crash tests, but the IIHS did award the mechanically related C-Class sedan with a Top Safety Pick + award 2019.

Standard safety features on the C63 include cross-wind and blind-spot assist as well as ten airbags. The C-Class also comes standard with forward collision warning, pedestrian detection, automatic emergency braking, driver attention monitoring, and a rearview camera.

2021 Mercedes-Benz AMG C 63 Convertible Competition

2021 Mercedes-Benz AMG C63 Vs BMW M4 Convertible

BMW and Mercedes-Benz have been mortal enemies for decades, and it has always been interesting to see how they go about building cars that compete in the same classes. BMW tends to create more driver-focused machines, while Mercedes-Benz has preferred the more laid back luxury approach. 

BMW M4 Convertible

The C63 might have a larger and more powerful engine, but both will do 20 mpg on a combined cycle. On the inside, the BMW offers more space but doesn't feel as sumptuous as the Merc; instead, it feels clinical and clean cut. Where the BMW really shines is on track, where it feels sharper and more intuitive. 

2021 Mercedes-AMG C63 Cabriolet vs. Jaguar F-Type

Firstly it should be said that the Mercedes-AMG C63 Convertible offers space for two more human beings than the F-Type, which is strictly a two-seater sports car: that will be the most significant deciding factor for most looking to buy in this price range. The F-Type has been around for a while now, and its good and bad traits are well-known. 

Jaguar F-Type Convertible

To be genuinely competitive in terms of performance, you'll have to stretch for the 380-hp supercharged 3.0-liter V6, at least, which costs over $10,000 more than the Merc - another big factor to consider. 

2021 Mercedes-Benz AMG C 63 Convertible Final Verdict

The mighty Mercedes-AMG C63 blends exhilarating performance with quality in a usable everyday package. It is fast, but it's also expensive and unrelenting. The C 63 cabriolet has the material richness, tactile quality, and infotainment sophistication to feel like an authentic luxury product. It delivers rear-wheel-drive handling that will put a grin on any driver's face.
