2020 Mercedes-Benz C-Class Convertible Review

byCameron Rogers^{Senior News Editor
Cameron Rogers has worked in the automotive industry since 2013. He has tested and reviewed hundreds of vehicles over the course of his career.}

Pros

Interior is impeccably crafted
Many available cutting-edge features
A range of high-horsepower engines available

Cons

Clumsy touchpad infotainment interface
C 300's optional sport suspension is rides too harshly
Limited cargo room

What's new

A few previously optional features are now standard
Part of the fourth C-Class generation introduced for 2015

The 2020 Mercedes-Benz C-Class is a versatile small luxury car in sedan, coupe and convertible body styles, each with the choice of three distinct engines. Its richly detailed cabin distinguishes it from cost-cutting forebears and exudes the quality that premium-car buyers expect. It's not the newest or most competitive car in the segment, but the C-Class is still a great buy, provided you check the right options boxes.

Edmunds Expert Rating

Our Verdict^{The Edmunds Vehicle Testing Team evaluates a fresh batch of vehicles every week, pairing objective assessments at our test track with real-world driving on city streets, freeways and winding roads. The data we gather results in our Expert Ratings. They’re based on 30-plus scores that cover every aspect of the automotive experience.}

7.5 /10

The C 300 Cabriolet flatters its occupants with all the trappings of a modern Mercedes. Its well-crafted interior and advanced technology are at the top of the class. But when fully optioned, it can be more than a bit expensive. And some of those options, such as the sports package and larger wheels, do more harm than good.

Rated for you by America’s best test team.

Performance

8.0/10

How does the C-Class drive? The C 300 Cabriolet's turbocharged four-cylinder is sufficiently quick and provides more than adequate power for passing slower traffic. It brakes well too. It's easy to stop smoothly in routine driving or quickly in emergencies. The nine-speed automatic transmission performs with luxury-car smoothness in everyday situations. The auto stop-start system is less refined and rocks the car when the engine churns to life.

The C 300, when fitted with the optional sport-tuned suspension, feels planted and secure when driving around turns. The steering effort has an appropriate amount of heft at higher speeds, allowing for more precise and predictable control than you might expect from an entry-level convertible. The optional summer tires provide an almost surplus of grip.

Comfort

7.0/10

How comfortable is the C-Class? The C-Class Cabriolet's single most significant problem is its rough ride. The C 300 should be the most relaxed and comfortable trim in the lineup, but our tester's AMG line package (which includes a sport-tuned suspension) should be avoided at all costs. The optional 19-inch wheels, which our car also had, don't help either.

The well-insulated top keeps the interior comfortable when it's up, but the climate system is no match for the top down on a cool day. Again, with the top up, outside noise is barely noticeable. Stowing the top creates more wind buffeting than we expected, and the C 300 exhibits severe body shudder and shake on broken roads.

On the other hand, the front seats offer plenty of adjustment and lateral support. The padding is firm, but the contoured surfaces make them comfortable for long drives.

Interior

8.0/10

How’s the interior? The C-Class' interior impresses with a graceful-looking dashboard and minimalist control layout. Though Mercedes pared down the physical buttons, it uses on-screen buttons in the infotainment system. Its menu structure is a little complicated and takes time to learn.

Otherwise, the cabin is quite nice. The front seats are spacious enough that tall adults won't feel confined, and the driver's seat offers a multitude of adjustments so you can find a perfect position. The back seat is predictably cramped for a luxury convertible, and the rear view is compromised by the small rear window and rear headrests.

The power top takes about 20 seconds to raise or lower, and it can be operated at speeds up to 30 mph. When stowed, the top is concealed under a nicely finished hard cover.

Technology

8.5/10

How’s the tech? The C-Class' infotainment system requires a bit of a learning curve but has great-looking graphics. You can also use a variety of inputs to operate it, such as wheel-mounted touchpads or the central control knob. The optional 12.3-inch display and Burmester audio system are also great.

While it lacks the newest MBUX system found in new Benzes, the C-Class' voice recognition system is accurate, even with the top down at highway speeds. The advanced safety systems work well overall and avoid triggering false alarms.

Storage

6.5/10

How’s the storage? It should come as no surprise that you'll need to make some sacrifices with a convertible when it comes to utility. The trunk only measures 8.8 cubic feet, so fitting luggage for a weekend getaway might be a challenge. In-cabin storage isn't plentiful either, but the bins and pockets that do exist are well-sized.

As is typical for most small convertibles, a rear-facing child seat will simply not fit if there's a passenger in front. But at least the car-seat anchor points are clearly marked and easy to access.

Fuel Economy

6.0/10

How’s the fuel economy? The EPA estimates its fuel economy at 24 mpg combined (21 city/29 highway), which is a few mpg lower than rivals. As a result of our enthusiastic driving style in our test car, we didn't even manage to break past an 18-mpg average.

Value

7.0/10

Is the C-Class a good value? In price, it starts close to the BMW 4 Series and the Audi A5. While the Mercedes does inhabit the luxury end of the spectrum, options can add up very quickly. Our loaded-up C 300 test car came close to $70,000, which is a lot for a small base-trim luxury convertible. The excellent materials and build quality at least makes it easier to swallow the bitter pill of the price tag.

A four-year/50,000-mile basic and powertrain warranty is average for the class, as is roadside assistance for the same parameters. Complimentary scheduled maintenance is not included.

Wildcard

7.5/10

If a Mercedes-Benz convertible is at the top of your shopping list, you will not be disappointed with the C 300 Cabriolet. For the occasional top-down trip in perfect weather, it's tough to beat. But when the weather or the roads aren't perfect, the car's shortcomings in ride comfort and refinement are a little too obvious.

Which C-Class does Edmunds recommend?

Though we remain absolutely captivated by the V8 models, most buyers will find the standard C 300 and its turbocharged four-cylinder offer enough performance. Mercedes offers a wealth of options, but keep it simple to avoid sky-high pricing. The main packages to consider are the Premium package (Burmester premium audio system, ambient lighting and satellite radio) and the Driving Assistance package (adaptive cruise control and other driver aids).

2020 Mercedes-Benz C-Class models

The 2020 Mercedes-Benz C-Class Cabriolet is a four-seat luxury convertible sold in trims that correspond with increasing levels of performance — C 300, C 300 4Matic, AMG C 43, AMG C 63 and AMG C 63 S. The C 300, AMG C 63 and AMG C 63 S are rear-wheel-drive, while the C 300 4Matic and AMG C 43 are all-wheel-drive. All use a nine-speed automatic transmission.

The C 300 and C 300 4Matic come standard with a turbocharged 2.0-liter four-cylinder engine (255 horsepower, 273 lb-ft of torque). You also get LED headlights, 18-inch wheels, a power-closing trunklid, dual-zone automatic climate control, a power-adjustable steering wheel, heated front seats with neck heaters, adjustable ambient lighting and simulated leather upholstery (MB-Tex).

Standard tech includes the COMAND infotainment system with a 10.3-inch central display screen, Apple CarPlay and Android Auto smartphone integration, and a 13-speaker Burmester audio system with satellite radio and two USB ports. Safety systems include a blind-spot monitor and forward collision warning with automatic emergency braking.

The AMG C 43 primarily adds a turbocharged 3.0-liter V6 (385 hp, 384 lb-ft), upgraded brakes, a sport-tuned suspension with selectable damper settings, an aerodynamic body kit, additional driving modes, a sport exhaust, sport front seats and simulated-suede seat inserts.

The AMG C 63 and AMG C 63 S offer similar equipment, with the notable difference of a turbocharged 4.0-liter V8 (469 hp, 479 lb-ft with the C 63; 503 hp, 516 lb-ft with the C 63 S), a high-performance transmission, an electronic limited-slip rear differential and launch control. The AMG C 63 S also adds 19-inch wheels, dynamic engine mounts, additional traction settings and leather upholstery.

Some features on the high-performance models can be added to the lower trims as well. Several packages are optional across all trims. These include the Multimedia package (navigation and enhanced voice commands), the Parking Assistance package (automated parking and a surround-view camera), and the Driving Assistance package (adaptive cruise control, lane departure warning and a lane-centering system).

Notable stand-alone options, depending on trim, include ventilated front seats, a digital instrument panel, a head-up display and a wireless charging pad. The AMG C 63 S is exclusively available with high-performance carbon-ceramic brakes.

Silver and Red Beauty

Joseph ATX,10/27/2020

C 300 4MATIC 2dr Convertible AWD (2.0L 4cyl Turbo 9A)

I’ve had this car for over a year. I had to order the car to get silver with a red interior and top with the driver assist package. It’s a very comfortable car. I took a 4K mile road trip as soon as it arrived. On the road it got 32 to 33 mpg. The ride is smooth and the acceleration is good. The driver assist package has some nice features. I got it mainly for adaptive cruise control.

C300 Cabrio

Hiram,03/03/2020

C 300 2dr Convertible (2.0L 4cyl Turbo 9A)

Awesome performance for a 4 cylinder. Great technology and comfort options. White with saddle brown leather and dark brown soft top looks classy. The details and quality of the vehicle is great.

Should I lease or buy a 2020 Mercedes-Benz C-Class?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
