#1 in Best Small Luxury Cars of 2020

No longer a mere gateway to Mercedes-Benz ownership, the C-Class has matured into a prestigious, elegant and advanced car in its own right. Today, it serves as a step up from the A-Class and CLA-Class models, and is offered in sedan, coupe and convertible body styles.

Looking and feeling like a smaller version of the Mercedes-Benz S-Class flagship models, the C-Class received a mid-life freshening for the 2019 model year. For 2020, it gains standard equipment across the board, making it a better value at its starting price of nearly $42,500.

That’s higher than primary rivals, including the Audi A4 and BMW 3 Series. Newer competitors such as the Cadillac CT5 and Volvo S60 promise greater value, while the often-overlooked Genesis G70 supplies thrilling dynamics at a bargain price.

But then, Mercedes ownership has never been about the deal, has it?

2020 Mercedes-Benz C-Class Pricing

2020 Mercedes-Benz C-Class pricing starts at $23,118 for the C-Class C 300 Sedan 4D, which had a starting MSRP of $46,865 when new. The range-topping 2020 C-Class C 300 4MATIC Cabriolet 2D starts at $33,057 today, originally priced from $58,565.

Driving the Mercedes-Benz C-Class

Driving a Mercedes-Benz C 300 is similar to the experience found in its larger and more expensive E-Class and S-Class siblings, but in a smaller and nimbler form.

While it looks stately and dignified on the outside, a C 300 is willing to hustle. In spite of its turbocharged 4-cylinder engine, it accelerates to 60 mph in just 6.2 seconds. Aside from being quick, this car is remarkably stable and smooth. We tested the latest version of the C 300 on the Autobahnen of Germany, happily cruising at 100 mph and confidently reaching the car’s governed speed of 130 mph.

The C 300’s 9-speed automatic transmission works well with the 255-horsepower engine, and a driving-mode selector offers a choice among Eco, Comfort, Sport and Sport+ settings. In use, changing the driving modes clearly alters the car’s character, and in Sport mode a C 300 feels much like a BMW 3 Series or 4 Series from behind the wheel.

Naturally, the C 300 Coupe feels a bit sportier than the C 300 Sedan, while the C 300 Cabriolet isn’t quite as rigid, what with its missing roof structure and all. In any case, a 2020 Mercedes-Benz C-Class is a proper German driving instrument, making it enjoyable during both commutes and road trips.

Interior Comfort

Sometimes, you fall in love with a car’s styling only to find disappointment on the inside. That’s not the case with the 2020 Mercedes-Benz C-Class. In fact, the inside of the car is more stylish than the outside, possessing an elegant glamour that is uncommon in more expensive vehicles let alone in this Benz’s primary competition.

Available with an array of leather, wood and aluminum materials and in a variety of colors, the C-Class is easy to personalize. And when you’ve chosen your favorite combination, you’ll find the cabin to fit like a custom-tailored suit — a little snug, but comfortable.

Equipment upgrades for 2020 make the larger 10.25-inch infotainment display standard for sedans, while coupes and convertibles benefit from standard Burmester sound and 64-color ambient cabin lighting. Get the C 300 Cabriolet, and when the top is dropped a newly standard AirCap system prevents excessive turbulence in the cabin.

Exterior Styling

Curvy, bold and beautiful, every version of the C-Class looks just like a shrink-wrapped S-Class. In fact, depending on equipment and the angle from which you’re viewing the car, you might be hard-pressed to tell the difference without more than a glance. The design might be a half-decade old, but it still looks just as fresh as it did in 2015.

Coupes and Cabriolets look similar to the Sedan from the windshield forward, but from the front doors back they adopt their own styling, most notably in the horizontal taillights that bleed into the decklid. As is true of any car, larger and more expressive wheel designs give the C-Class more presence, and the C 300’s AMG Line design package adds a gorgeous chrome-studded grille that really helps the car to stand out.

Favorite Features

THAT INTERIOR
The C-Class might be expensive in relationship to its competitors, but the interior makes it feel worth every penny — especially when you load it up with supple leather, heated and ventilated front seats, and the cabin air-ionization and fragrance system.

BURMESTER AUDIO SYSTEM
This German audio brand might be unfamiliar to American buyers, but once your ears experience the high-quality sound, you’ll never forget it. Standard in the coupe and convertible, and a remarkably affordable option for the sedan, this upgrade is an aural delight. Even the stainless-steel speaker grilles please the senses.

Standard Features

This year, perhaps in an effort to add perceived value, Mercedes adds standard equipment to all three versions of the 2020 C-Class. Sedans now have standard 18-inch AMG-style aluminum wheels, a 10.25-inch infotainment system display screen, keyless passive entry, hands-free access to the trunk, and a power trunk lid closer.

To this list, Coupes and Cabriolets install power-folding side mirrors and the contents of the previously optional Premium Package: a Burmester premium surround-sound audio system, SiriusXM satellite radio with a free 6-month trial period, and 64-color ambient interior lighting with illuminated doorsills. Additionally, the Cabriolet has a standard AirCap system that reduces cabin turbulence when the convertible top is down, and a semi-automatic trunk separator that makes using the top easier.

Standard equipment highlights for all three C-Class body styles include LED headlights and taillights, rain-sensing wipers, a driver-monitoring system, power-adjustable front seats, and dual-zone automatic climate control. Infotainment systems equip the cars with Apple CarPlay, Android Auto and a free 3-year subscription to Mercedes Me Connect services.

Factory Options

When you buy a luxury car, you expect luxury. Often, however, features like metallic paint, leather seats and navigation are options, which is the case with the 2020 C-Class. You’ll even pay extra for driving-assistance and collision-avoidance technologies that are standard in much less expensive vehicles.

Aside from these upgrades, the C-Class offers AMG Line body and interior styling with sport-tuned performance components. A variety of wheel designs is available, along with heated and ventilated front seats, a heated steering wheel, and fancier interior trim.

The Sedan’s Premium Package adds ambient interior lighting, Burmester audio and satellite radio, and both a panoramic glass sunroof and triple-zone climate control are options for the 4-door. Each version of the C-Class offers a Multimedia Package with navigation and Car-to-X communications technology, digital instrumentation, a head-up display, and wireless smartphone charging.

Engine & Transmission

Every 2020 Mercedes-Benz C 300 is equipped with a turbocharged 2.0-liter 4-cylinder engine good for 255 horsepower and 273 lb-ft of torque. The peak torque arrives at 1,800 rpm, holding steady until 4,000 rpm. After that, peak horsepower kicks in from 5,800 rpm to 6,100 rpm.

A 9-speed automatic transmission equipped with paddle shifters transfers the power to the rear wheels (RWD) unless you’ve specified the 4Matic all-wheel-drive (AWD) system. This system is continuously monitoring driving style and traction at the surface, optimizing power delivery to each of the car’s four wheels.

An automatic engine stop/start system is standard. It helps to improve fuel economy, but you can disable this function if it bothers you. With rear-wheel drive, the C 300 gets between 24 mpg and 28 mpg in combined driving, depending on body style. With 4Matic, those numbers dip to a range of 23 mpg to 26 mpg.

2020 Mercedes-Benz C-Class Safety

2020 Mercedes-Benz C-Class Safety Technology

Pre-Safe

Standard in every C-Class, Pre-Safe determines when a collision is about to occur, and it prepares the cabin and occupants for impact by tightening the seatbelts, closing the windows and sunroof, and better positioning the front-passenger’s seat for optimum impact protection.

Active Emergency Stop Assist

Part of the optional Driver Assistance Package, this technology works in conjunction with the active cruise control and lane-keeping assist systems. It senses when a driver is no longer holding the C 300’s steering wheel, and if the driver fails to respond to requests to retake control, the system assumes the driver has fallen asleep or has suffered a medical emergency. It then begins to slow the car down, ultimately bringing it to a stop with the hazard flashers activated.

Evasive Steering Assist

Also part of the optional Driver Assistance Package, Evasive Steering Assist helps a driver to retain control of the C-Class in situations where sudden evasive steering is necessary to avoid a pedestrian, an animal or other object.

FAQs

What is a Mercedes-Benz C-Class?

Which Mercedes C-Class is best?

It all depends on your definition of “best.” The most expensive C-Class is the AMG C 63 S Cabriolet, and the best performing C-Class is the AMG C 63 S Coupe. Neither of these models is best at carrying passengers in the back seat, though, or helping you to invest money in the stock market.

2020 Mercedes-Benz C-Class city/highway fuel economy ratings range from 21/30 mpg to 24/35 mpg, depending on trim and equipment.

How much should a 2020 Mercedes-Benz C-Class cost?

Used 2020 Mercedes-Benz C-Class prices currently range from $23,118 for the C 300 Sedan 4D to $33,057 for the C 300 4MATIC Cabriolet 2D when purchasing from a dealership, depending on a range of factors like equipment, mileage, and condition.

What's the cheapest Mercedes-Benz C-Class?
