2021 Mercedes-AMG C63 Cabriolet

2021 Mercedes-AMG C63 Cabriolet Review: Class And Muscle

Mercedes-AMG has produced some killer supercars of late, but we sometimes feel that the brand's less powerful drop-tops get overlooked. Case in point: the 2021 Mercedes-AMG C63 Cabriolet. Sure, these convertibles add a bit of weight and they might not be so tight in the corners, but the act of losing the roof adds a ton of pleasure to the driving experience, and isn't that what sports cars are all about? The 2021 C63 Cabriolet remains mostly unchanged for the new year, but that's not a bad thing at all: you still get 469 horsepower (or 503 hp in the S) out of a sublime 4.0-liter twin-turbo V8 engine, along with interior and exterior styling that will melt the heart of anyone that has one. The C63 Cabrio goes up against traditional foes such as the BMW M4 Convertible, which is soon due to be replaced by an all-new model.

2021 Mercedes-AMG C63 Cabriolet Changes: 🚙What’s the difference vs 2020 AMG C63 Convertible?

Mercedes-AMG has not done much to change up the C63 Cabriolet for 2021. A 12.3-inch digital cluster is now standard, but otherwise, things stay the same.

Pros and Cons

  • It's a stunner
  • Awesome engine
  • Impressive handling for an open-top car
  • Beautiful cockpit
  • You'll have to pay extra for advanced driver assistance tech
  • The warranty is a bit disappointing
  • It can't be sunny all year round

AMG C63 Convertible Exterior

The hardtop C63 is already a stunner of a car, but the Cabriolet is arguably even better looking, especially with the top down. Mercedes-AMG has given this car an aggressive look thanks to a set of 18-inch AMG 10-spoke wheels (19-inch, five-spoke wheels on the C63 S Cabriolet) and an AMG body kit that includes a vertical-bar AMG grille, sculpted side sills, and four trapezoidal AMG exhaust outlets at the back. Mercedes-AMG also offers 19-inch alloy wheels for the base model and a Night Package, which adds deep Gloss Black accents to the side mirrors, side-sill inserts, and rear diffuser.

Engine and Transmission

This car's biggest party trick isn't the fact that it can lose its head but that it can snap your neck. Under the hood of the 2021 Mercedes-AMG C63 Cabriolet lies a twin-turbocharged 4.0-liter V8 engine that produces a tasty 469 hp and 479 lb-ft of torque. Power is sent to the rear wheels via a nine-speed automatic transmission. With so much power on tap, the C63 Cabriolet accelerates effortlessly and feels indecently fast when you keep your foot in it. All that low-down torque also makes for a relaxed city driving experience and there is always enough power when you need it. The C63 Cabriolet will do the 0-60 sprint in four seconds flat. If you're looking for an even crazier experience, Mercedes-AMG simply adds an "S" to the model name, and the result is 503 hp and 516 lb-ft. This drops the zero to sixty sprint time down to 3.9 seconds and increases the top speed to 180 mph. The nine-speed transmission is on par with modern autos but not as sharp as a true DCT.

Handling and Driving Impressions

The coupe impressed us with its razor-sharp handling, and the good news is that we found much of the same was apparent in our AMG C63 Cabriolet review. This car still handles like it's on rails. The C63 Cabriolet comes standard with AMG Ride Control Sport Suspension with three-stage damping and the AMG Dynamic Select driving modes, which gives you a wide range of driving configurations. Scuttle shake is virtually absent from the cabin of the compact convertible, but the ride can get jarring when the car is being driven in its sportier settings. With the larger wheels fitted, the C63 Cabriolet can become unsettled at lower speeds. We recommend having it in comfort mode the majority of the time. Go for the S variant, and you also get access to a Race mode that is tuned for use on a track and reduces the intervention of the car's electronic systems.

AMG C63 Convertible Gas Mileage

When you stick two turbochargers onto a high-performance V8 engine, you can expect awesome power figures and disgusting fuel consumption numbers. Mercedes-AMG has managed to keep the C63 Cabriolet civilized enough in this category: Both the C63 and C63 S will return a respectable 17/25/20 mpg on the city/highway/combined cycle. It is interesting to note that the more powerful C63 S won't use any more fuel. That combined figure is guaranteed to end up in the teens when you spend most of your time in the city or suburbia. With a 17.4-gallon tank of premium gas onboard, the C63 Cabriolet should see a max range of 348 miles.

Seating and Interior Space

Yes, this might be a topless muscle car, but it is still a Mercedes, and for that reason, the 4-seater C63 Cabriolet offers one of the best looking interiors amongst its competitors. Not only does it look great, but the 2-door cabrio will seat four adults in comfort. In the front, the 42 inches of legroom should be enough for six-footers and above. Things naturally get a lot tight in the back, but the space is still usable: with 32 inches of legroom, smaller comrades will be able to remain comfortable for short journeys. The sport seats in the front are heated and feature 14-way power adjustability with memory. The C63 S has Nappa leather, replacing the MB-Tex/Dinamica used in the C63.

AMG C63 Convertible Trunk and Cargo Space

Anyone interested in a C63 Cabriolet will not care much about cargo space or practicality in general, but that is not to say you can't live with the C63 Cabriolet daily; you just won't be able to carry much stuff. The C63 Cabriolet offers 8.8 cubic feet of trunk space where the top is up. This is enough space for a small trip to the shops or one large and one small suitcase. The rear seats also split 50/50 for even more practicality. The new BMW 4 Series Convertible offers nine cubes of trunk space, indicating that the upcoming M4 Convertible should be able to do the same. The closest thing that Audi has to this is the S5 Convertible with its trunk measuring a smaller 7.3 cubes. Inside the cabin, the C63 offers a glovebox, a center console storage bin, and a small nook in front of the shifter. Those in the back get a fold-out armrest.

AMG C63 Convertible Infotainment and Features

Features

You get what you pay for, as they say, and in the 2021 C63 Cabriolet, you get quite a lot. This drop-top features 14-way power-adjustable and heated front seats, an Airscarf neck heating system and Aircap a system which cocoons occupants in what is essentially an air bubble. You also get dual-zone automatic climate control, remote start, a 64-color ambient interior lighting system, a power soft top, a garage door opener, and driver assistance features such as active brake assist, attention assist, and blind-spot warning with exit warning assist. The exterior also features LED headlights, power-folding mirrors, and an illuminated entry system.

Infotainment

The previously optional 12.3-inch digital driver's display is now standard, and is complemented by a 10.25-inch central color display. Graphics for both screens are crisp, but some might find the system a bit too complicated to use. The driver can access the screen menus via the console controller or right touch control buttons on the steering wheel. This system includes all the contemporary features you'd expect from a car in this class, including Apple CarPlay and Android Auto integration, a 13-speaker Burmester sound system with a FrontBass system, Bluetooth streaming, dual USB audio ports, HD Radio, and SiriusXM radio. AMG Track Pace is optionally available as an easy way to record and store performance data, while wireless charging is also on offer.

2021 Mercedes-AMG C63 Convertible Problems and Reliability

The 2021 Mercedes-AMG C63 Cabriolet has been recalled twice, first for a malfunction with the vehicle location for emergency services, and then for an issue with the front seatbelts which may not fully retract.

Mercedes-AMG will cover the C63 Cabriolet with a four-year/50,000-mile basic warranty, including corrosion cover, a drivetrain warranty, and roadside assistance for the same time period and mileage.

Warranty

  • Basic:
    4 Years \ 50,000 Miles
  • Drivetrain:
    4 Years \ 50,000 Miles
  • Corrosion:

  • Roadside Assistance:

AMG C63 Convertible Safety

The high price of the 2021 AMG C63 Convertible means that like most other sports cars, it hasn't been sent for a safety review by the NHTSA or IIHS, so, unfortunately, there is no official crash safety rating available for this vehicle. On the other hand, its distant cousin, the C-Class Sedan, is one of the safer cars on the road and has placed close to the top on both the IIHS and NHTSA rankings.

The new AMG C63 Cabriolet includes safety features such as ten airbags - including front knee airbags and side airbags for all outboard occupants - crosswind assist, blind-spot warning, a rearview camera, attention assist, and active brake assist. The optional Driver Assistance Package adds features such as active steering assist, adaptive cruise control, and evasive steering assist for $1,700.

Key Safety Features

Verdict: 🏁Is the 2021 Mercedes-AMG C63 Cabriolet a good car?

Mercedes-AMG has been building some of the best performance cars the world has ever seen in recent years, and while most focus on the hardcore hardtop versions, the cabriolets are just as good. The C63 Cabriolet manages to strike an outstanding balance between being a laid back drop-top and a capable sports car thanks to its relatively compact dimensions and sorted chassis. This car is a force to be reckoned with and will surprise many dedicated sports cars on the road. Its engine is simply phenomenal, and there is always power on tap as long as you ignore the fuel bills. While not as dynamic as a BMW M4, the handling is sharp and still offers good feedback. On the interior side of things, very little beats the C63 Cabriolet. The cabin is beautifully put together and feels genuinely luxurious. The C63 Cabrio is surprisingly practical and will haul four people and a good amount of stuff with ease. It's pretty, it's fast, and it can lose its top. Awesome.

🚘What's the Price of the 2021 Mercedes-AMG C63 Cabriolet?

You've got two options here: go for the base model C63 Cabriolet, or ramp up the power with the C63 S Cabrio. The catch is that the S adds quite a few dollars to the price tag. The base car comes in with an MSRP in the US of $78,000 excluding tax, registration, and a destination fee of $1,050. To drop 0.1 seconds off your 0-60 sprint time and add an "S" logo to your behind, you'll have to cough up an extra $7,600. To put these prices into perspective, the C43 Cabriolet will cost you $65,500, and the larger but less powerful E53 Cabriolet will set you back $82,850. The all-new BMW M4 Convertible hadn't arrived at the time of writing, but it'll be one of the most exciting drop-tops for sale when it does arrive in the USA.

Additional Packages

🚗What Mercedes-AMG C63 Cabriolet Model Should I Buy?

Both Mercedes-AMG C63 Convertible models are worth a look, but considering that this car will rarely, if ever, see a track, it wouldn't make sense to spend the extra money on a slightly more powerful C63 S. We would rather spend that extra money on extra options on the base model. With 469 hp and a ton of torque on offer, the C63 Cabrio offers more power than most will ever be able to exploit fully on public roads, and it does so while carting its occupants around in extreme luxury. We would take the extra $7,600 we'd save by not getting the C63 S and spend it on the $1,700 Driver Assistance Package, which adds features such as active steering assist and evasive steering assist. We'd also splurge on the head-up display and adaptive high beam assist. This would perfectly round off a car that already offers standard LED headlights, dual-zone climate control, Apple CarPlay, Android Auto integration, power seats, and more.

2021 Mercedes-AMG C63 Cabriolet vs Mercedes-AMG C43 Convertible

Trying to figure out the Mercedes-Benz and Mercedes-AMG lineup of cars can get seriously confusing, but all you need to know for this comparison is that 43 is less than 63, which means less power and a lower asking price. These cars are based on the same platform, share similar dimensions, and offer the same type of interior experience and build quality, but the most significant difference takes place under the hood. The C43 Cabrio is powered by a twin-turbo 3.0-liter V6 engine that produces 385 hp and 384 lb-ft of torque. That is almost a hundred less horsepower and torque. Another big difference is the fact that the C43 Cabrio sends its power to all four wheels via the brand's 4Matic system, instead of just the rears in the C63 Cabrio. The C43 is still blisteringly fast and should be more than a handful for the everyday driver. If you're power-hungry, the C63 is the way to go, but if you're just looking for some "cheap" casual fun, the C43 Cabriolet is the one to go for.

2021 Mercedes-AMG C63 Cabriolet vs Mercedes-AMG E53 Convertible

The E53 Cabriolet sits above the C63 Cabriolet in the AMG lineup. It's bigger and has a more expensive price tag. The E53 drop-top is a physically larger car and rolls on a 113.1-inch wheelbase, while weighing over 300 pounds more. Under the hood, this executive muscle car packs a 3.0-liter turbocharged straight-six that produces 429 hp and 384 lb-ft. Its party trick is an electric motor that adds another 21 hp and 184 lb-ft of torque. This virtually eliminates turbo lag and makes this battleship feel faster than the numbers suggest. The official 0-60 sprint takes 4.4 seconds, and this car will top out at 155 mph. The E53's tech specs are better, as it uses the more up-to-date MBUX system. It also offers more space and a larger trunk. The E53 Cabriolet starts at $82,850 and should be your choice if you enjoy a more laid back cruise.
