Editor's Overview

The 2018 Mercedes-Benz C-Class compact luxury car is a prestigious chip off the old block. Its design, technology and very essence are derived from the S-Class, Mercedes' nearly 6-figure flagship. The C-Class is far more attainable, and if the S-Class shouts that its driver has made it, this one says theirs is getting there.

You'll Like The 2018 Mercedes-Benz C-Class If...

Whether you're drawn to its craftsmanship, elegant styling, technology or coveted German badge, the Mercedes-Benz C-Class remains the entry-level luxury car to which others aspire. The C-Class even offers high-performance Mercedes-AMG models (reviewed separately) and a plug-in hybrid version called the C350e.

You May Not Like The 2018 Mercedes-Benz C-Class If...

The C-Class' features and enviable reputation come at a price that starts higher than those of its rivals. If you want a compact luxury car that's as distinctive as it is practical, you might like the roomier Audi A5 Sportback or BMW 4 Series Gran Coupe.

What's New

For 2018, all C-Class models except the hybrid receive a 9-speed automatic transmission (the hybrid retains a 7-speed). Sedan models gain a power sunroof as standard, while the coupe gets a rearview camera and blind-spot monitoring. Cabriolets receive a semi-automatic trunk separator, wood trim and analog clock. All models now have extendable sun visors.

Interior Features

Lovely. Few other words suffice when it comes to describing the 2018 Mercedes-Benz C-Class interiors, especially on the heels of the former generation, which had more of a cold, clinical demeanor. The C-Class is available with an attractive array of wood and aluminum finishes, and a relatively clutter-free layout that manages to still feel elegant. Central to the de-cluttering is a simple rotary dial and optional touch pad that respond to gestural inputs, swipes and handwriting. Adding to the upscale feel is an available Air Balance Package with a fragrance diffuser that atomizes perfume into the air-conditioning system. Pragmatically, rear-seat legroom can be tight for taller passengers, and coupe and convertible model trade the sedan's 3-passenger bench for a pair of more sculpted seats.

Exterior Features

The C-Class' elegant interior isn't its only correlation to the S-Class. Like that flagship, the C-Class is curvy, bold and beautiful. Thanks to its smaller proportions, you could say it's even more purposeful. The 2-door versions of the C-Class, in the form of the coupe and cabriolet, have their own sense of style, with the coupe looking particularly strong. All can be further emboldened with the Night Package, which adds sporty AMG Line performance elements, gloss black exterior accents, and darkened 18-inch AMG wheels.

Driving Impressions

The C-Class drives with a similar stateliness as its E-Class and S-Class brothers, but in smaller, nimbler form. While comfort and quiet are top of mind, the C-Class is easy to hustle. In fact, the 2018 C-Class is beguilingly quick, and its turbocharged 4-cylinder feels more powerful than its stated 241 horsepower. With the new 9-speed transmission, the C300 now runs to 60 mph in 5.8 seconds, 2/10ths of a second quicker than last year. And while we've had our issues with 9-speed automatic transmissions in other cars, in the C-Class we didn't experience any hesitancy or refinement issues. Various drive modes are on top via the Dynamic Select dial, and they truly change the personality of the car, with the Comfort, Sport and Sport+ modes doing justice to their names in both acceleration and cornering dynamics. (There's also an Eco mode for the efficiency-minded.) Speaking of fuel economy, the C-Class is fitted with a stop/start system that cuts engine power at idle. If you're like us and have qualms with the engine shutting down and abruptly restarting, know the system can be turned off.

Pricing Notes

The 2018 Mercedes-Benz C-Class has a Manufacturer's Suggested Retail Price (MSRP) starting just over $41,000, including destination charge. Base C-Class coupe models start at just over $44,000, while the C-Class convertible jumps to starting price of over $52,000. Adding all-wheel drive to any model is an extra $2,000. The C-Class Plug-in Hybrid, available as a sedan only, starts just over $47,000. Options and packages can easily lift these prices by thousands. A C-Class sedan, for example, can reach into the mid-$50,000 range. At these prices, the C-Class sits above most competitors. A base C-Class would be in lock-step with the BMW 3 Series, if not for the newer and lower-priced 320i. Other rivals, such as the Audi A4, Cadillac ATS, Lexus IS and Jaguar XE also start lower. Several thousand lower are the Volvo S60, Infiniti Q50 and Acura TSX. Before buying, check the KBB.com Fair Purchase Price to see what others in your area are paying for their new Mercedes C-Class. The Mercedes' resale value is expected to remain quite strong, though possibly not quite as high as that of the Lexus IS.

Notable Equipment

As should be expected from a German luxury car, even a base Mercedes-Benz C300 includes a laudable amount of features, technology and safety systems to complement its badge appeal. Among the standard features are power front seats, dual-zone climate control, a sunroof, power-folding mirrors, and a brake-hold feature that can give your foot a break at stoplights. Standard infotainment includes a 7-inch high-res display and central rotary controller, AM/FM/HD Radio, dual USB audio ports, and Bluetooth streaming. Apple CarPlay and Android Auto can be bundled for an extra $350. The C-Class' standard safety systems include an automatic emergency braking system and another system that monitors for driver drowsiness. C-Class convertibles come with the nifty Airscarf neck-level heating system and heated front seats.

Notable Options

Whether you want in-car Wi-Fi, a power rear sunshade, a hands-free trunk, or the ability to check on your car via a phone with the mbrace Connect service, there are plenty of ways upgrade the 2018 Mercedes C-Class. If you real leather instead of the faux MB-Tex upholstery, that is extra. Other options include heated and ventilated front seats, a panoramic roof, and performance-oriented suspension and brakes. In the "just cool" column are that in-cabin fragrance system with your choice of fragrances, a head-up windshield display, and a system that helps you parallel park. If you opt for the navigation system, you'll also get a larger 8.4-inch center display.

Favorite Features


You may never have heard of this high-end German audio brand, but once your ears hear the sound of this system, they'll never forget it. This 13-speaker, 590-watt audio system is an aural delight, and even its stainless steel speaker housings please the senses. At $850, it's a steal.


This package bundles significant active safety and driving aids, features that can make driving less stressful and potentially save a life. They include an adaptive cruise control system with a Steering Assist function that follows the road, and even the ability to stop the car if a pedestrian enters the road.

Under the Hood

The standard engine in the C300 sedan, coupe and convertible is a 2.0-liter turbocharged 4-cylinder that makes a healthy 241 horsepower. Rear-wheel drive (RWD) is standard, and all-wheel drive (AWD), which Mercedes calls 4Matic, is optional. For 2018, all are now linked to a 9-speed automatic transmission. Still using the 7-speed automatic -- a good transmission in its own right -- the C350e Plug-in Hybrid pairs a 2.0-liter turbocharged 4-cylinder with an electric motor to make a combined 275 horsepower and a stout 443 lb-ft of torque. Beyond more power, the system results in markedly more fuel economy: the mile-per-gallon equivalent (MPGe) of 45/61 city/highway. On electricity alone, it won't take you far, with the EPA putting its range at about 8 miles. The C350e is rear-drive only. If you're power hungry, the C-Class is available in high-performance Mercedes-AMG variants boasting up to 503 horsepower. Those models are reviewed separately.

2.0-liter turbocharged inline-4 (C300 sedan, coupe, convertible)

Editors' Notes

The 2018 Mercedes-Benz C-Class compact luxury car is a prestigious chip off the old block. Its design, technology and very essence are derived from the S-Class, Mercedes' nearly 6-figure flagship. The C-Class is far more attainable, and if the S-Class shouts that its driver has made it, this one says theirs is getting there. This is even more so with the C-Class coupe and convertible, which trade 5-passenger practicality for stylistic flair and a carefree attitude. Against its BMW 3 Series archrival, the C-Class tends to have slightly softer manners, but is still impressively athletic when pushed. Equally notable are the C-Class' roster of tech/safety features and amenities, right down to the interior fragrance system that broke ground in the latest S-Class.

The affordable definition of luxury Mercedes Benz c 300 4matic.

2018 Mercedes-Benz C-Class

The Mercedes c300 4matic is an exceptional luxury car for the price. Mercedes continues to offer advanced technical advances in mobility and function as well as satellite safety, navigation, communication and mobile entertainment devices. The consistently sophisticated design projects a sense of achievement and class. There is a special feeling cruising on an open road with the panoramic sunroof open to the sky while listening to your favorite tunes streamed through Pandora or your private collections. The art of driving is enhanced with such safety features as the side view vehicle crossover indicators and the life saving vehicle shut down braking system that proves to me Mercedes is not just another pretty face. Mercedes c 300 4matic provides a reliable start 4 out of 4 seasons blazing sun, rain, wind, ice and/or snow. And if by chance your car is disabled the embrace system will come to your rescue and aid you in securing proper help. Can you see yourself snuggled into the all comfortable leather seats properly adjusted to your height, arm reach and leg extension heated or not, your choice? You have the ability to touch the steering reel and adjust everything you could possibly need to your liking such as phone retrieval, stereo volume and a variety of console functions. Your family and friends will enjoy the comfort of the passenger seats with ample leg room and separate heat and air conditioning controls. There is more than ample room for shopping bags and boxes on the back seats and floor as well as the spacious trunk area. Just ask my husband! The drive selection options are comfort, economy or sport for that burst of speed and power that allows the driver to be in full control in all traffic situations. My one and only dissatisfaction is the placement of the computer screen sitting up on the console instead of embedded into the console. Does it stop me from loving my c300 4matic? No! Would I buy another one? I have owned three c 300 models previously, what do you think?

The car also has a sunroof to let the windy breeze inside.

2018 Mercedes-Benz C-Class Base

The problems I have with my Mercedes-Benz vehicle, is that it's second-handed so it's going to have slight problems. The battery in the car key is slowly going out, whenever I try to unlock the door it takes about 2 minutes for it to finally open. It has also seems like it's been a problem starting the car when I finally get in. It'll take about 10 seconds to start, but this only happens occasionally. And as it being a Mercedes, it constantly needs gas. Besides that the car works really well, it rides nice and smooth, it's honestly amazing. I would say this car is kind of reliable, it's really unpredictable when it's second-hand owned. The Mercedes has nice-coated leather seats but can be a pain in the summer. Its features looks luxurious with tinted windows in the backseat, with a nice sparkle on the paint of the car.

Best Car and Buying Experience of my Life

2018 Mercedes-Benz C-Class C 300

The best car I have ever purchased! and the buying experience through Mercedes Benz was great!, The car itself is very quiet, runs very well, it is much happier than the car I traded in. Mercedes Benz, seems more to want ensure I am happy with the car, it drives nice and is very well made, my only regret is that I wished we had purchased Mercedes Benz years ago when we were younger, and in reality they cost no more than any other domestic premium car
