Mercedes-Benz has a rather long and interesting history of making some legendary and brilliant automobiles. And the brand has stayed true to its rich heritage even today as well. Back in 1986, the brand was working to build a successor of the much-revered W201 sedan and introduced the all-new W202. Since then, the C Class has been one of the best-selling cars from the brand.

Expert Review, Pricing Analysis and Buying Guide

The 2021 Mercedes-Benz C Class comes with no significant changes apart from some minor feature upgrades and the addition of a new exterior appearance package. The sedan is built on the brand’s MRA platform which it shares with the bigger E Class and S Class sedans as well. The price for the sedan starts at $41,600 and comes with a standard 2.0-liter four-pot motor. In the segment, the sedan competes against the Lexus IS 300, Audi A4, and the BMW 3 Series sedans respectively.

The 2021 Mercedes-Benz C Class sedan is available in five trim levels which are C 300, C 300 4Matic, AMG C 43, AMG C 63, and AMG C 63 S. The AMG models are covered in separate reviews. The base C 300 sedan comes with a single-engine option and two drivetrain layouts, the AWD layout being named as 4Matic. Right in the stock form, the sedan comes fully equipped with a handsome list of features that leave very little to desire for optional packages and standalone features. However, the additional packages are not baseless either and offer a wide range of quite tasteful features to enhance your experience many folds. 

Some of the packages available include the AMG Line package which adds an aerodynamic body kit and a sport-tuned suspension setup, the Premium package that adds interior ambient lighting and a 13-speaker Burmester high-end audio system, the all-new Night Edition Package that includes both the Premium and AMG Line package along with blacked-out exterior accents and imitation suede seat inserts. Both the Parking Assistance Package and the Driver Assistance Package adds a wide array of advanced safety techs and parking aids to enhance the safety and ease of driving of the sedan.

Engine and Performance

The 2021 Mercedes-Benz C 300 gets a standard 2.0-liter turbocharged Inline-4 motor. The engine whips out a maximum of 255 horsepower and 273 lb-ft of maximum torque. In the segment, it is one of the most refined and sporty powertrains to be fitted in a compact luxury sedan and it proves that Mercedes-Benz is still capable of making brilliantly engineered powertrains. The engine is punchy and the power delivery is excellent throughout the rev range. The motor is mated to a standard 9-speed automatic transmission that offers seamless and quick shifts.

It also comes with a manual mode for a more enjoyable driving experience as well. By default, the sedan gets an RWD layout but is also available in an AWD or 4Matic layout as well. The 0-60mph timing of 5.7 seconds is quite decent for the segment along with the quarter-mile time as well.

The Lexus IS 300 is the least powerful sedan among the rivals here and has the most disappointing 0-60mph and quarter-mile times as well. The Audi A4 whips out the highest horsepower of 261hp among the rivals here and is the quickest one too from 0-60mph taking 5.2 seconds but is marginally slower to complete the quarter-mile stretch. The BMW 3 Series dishes out identical horsepower to the C Class but impresses with its segment-leading torque output of 295 lb-ft.

How well does the 2021 Mercedes-Benz C Class handle?

The handling of the sedan is decent as compared to the segment rivals but the AMG-powered models do offer some intense performance and superior handling. Even the AMG Line package makes the base sedan sportier with a sport-tuned suspension and an aerodynamic body kit for enhanced handling. Without the sport-tuned suspension, the ride quality is excellent at all speeds and the car shows exemplary high-speed stability out on the highways as well. Since the sedan comes with an RWD layout as standard it can be a tail-happy vehicle if thrown around a corner at high speeds but the 4Matic system improves handling and the driving dynamics to a great extent.

Braking Performance

The braking performance of the 2021 Mercedes-Benz C 300 is average at the most. It gets a decent 13.0-inch rotor at the front and an 11.8-inch rotor at the rear. Even though the car traverses 124ft before coming to a halt from 60mph, the brake feels confident and the pedal travel is minimal too. Also, the sedan has the lightest curb weight among the rivals here which also aids in a better braking performance too.

The Lexus IS 300 gets 12.3-inch rotors at the front and 11.4-inch rotors at the rear. It also has comparable braking performance to the Mercedes-Benz C 300 as well. The Audi A4 gets almost similar-sized rotors to the Lexus IS 300 and has similar braking performance too. The BMW 3 Series sedan gets 13.1-inch brake rotors at the front and 12.2-inch rotors at the back, delivering identical braking prowess to the Lexus IS 300 sedan, covering 125ft.

Fuel Economy

Luxury sedans have come a long way and with modern engined under the hood, the vehicles do return some impressive fuel economy figures as well. The 2021 Mercedes-Benz C 300 returns a city mileage of 24mpg while the highway mileage stands at an impressive 35mpg. The combined mileage is rated at 28mpg. The sedan also gets a big 17.4 gallons gas tank which allows it to offer some impressive driving range numbers of 487 miles.

The Lexus IS 300 is the least fuel-efficient sedan among the rivals here averaging 24 MPG. But with a similar-sized gas tank to the C 300, it makes up for the disappointing mpg figures to some extent. The Audi A4 has similar city mileage to the C 300 but has a considerably lower highway mileage. It also has a smaller gas tank than the C 300 resulting in lower driving range numbers. The BMW 3 Series delivers the highest fuel economy numbers of 30MPG among the rivals here bu with a smaller gas tank than the C 300, it fails to deliver the impressive numbers like the C 300.


The cabin of the 2021 Mercedes-Benz C 300 gets an elegant design with premium quality materials all over the interior. The doors open wide making it quite easy to get in and out of the sedan for both the front and rear passengers. The seats are well cushioned and adequately comfortable for both short and long journeys. The front seats get a heating function with driver’s seat memory settings. The dual-zone automatic control dials up the comfort levels to a great extent.

The rear seats are more comfortable than the front seats with a good recline angle and adequate headroom and legroom on offer. The cargo capacity is generous at 12.6 cu-ft.

The Lexus IS 300 has a better and more comfortable cabin than the Mercedes-Benz C 300 sedan and offers more headroom for the front passengers. The cargo space on offer is quite disappointing though with a mere 10.8 cu-ft. on offer. The Audi A4 gets an equally enticing cabin like the Mercedes-Benz C 300 and has excellent comfort levels with a finely crafted interior. The BMW 3 Series has the best cargo capacity of 13 cu.-ft on offer when compared to the rivals here and also offers a comfy cabin too.

Some of the standout interior features are as follows:

  • Driver's seat memory settings
  • Dual-Zone Automatic Climate Control
  • Remote Start via Mercedes Me connect 
  • 40/20/40 Split-folding rear seats
  • Keyless Start
  • Electronic Trunk Closer
  • Homelink garage door opener
  • Remote opening and closing of windows and sunroof

What’s there to keep you entertained?

The 2021 Mercedes-Benz C 300 gets a 10.25-inch infotainment display as standard. The system offers a neat and user-friendly layout with bright and crisp graphics. The system can be controlled via the touchpad controllers mounted on the steering wheels or the touch buttons placed on the center stack as well. However, the old rotary-knob-based controls were better. One can opt for the optional fully-digital gauge cluster that has a brilliant display and is completely worth the upgrade. Apple CarPlay and Android Auto are offered as standard. The optional Burmester audio system offers excellent audio output and surround listening experience.

Some of the highlights of the infotainment system are as follows:

  • 10.25-inch infotainment display
  • Steering wheel with touch controls
  • Apple CarPlay and Android Auto
  • Dual USB Audio Ports
  • Central Controller
  • Bluetooth Audio Streaming

Over the years, the Mercedes-Benz C Class sedan has become more appealing and handsome. The 2021 C 300 gets a bold and intriguing exterior design to boast of. The front end looks aggressive with the new front grille design and the sculpted lines on the hood give the sedan a distinct muscular appeal that is a rare find in the segment.

The all-LED headlamp units with the LED running lights look spectacular both day and night. The side profile has a sporty appeal with some sculpted lines emerging from the front fenders and flowing along with the doors to the rear end. The rear end looks graceful with a pair of compact yet elegant LED taillights.

The Lexus Lexus IS 300 is the most aggressive-looking sedan in the segment with the brand’s famous spindle grille design. The sedan is also longer than the C Class and looks sportier than the latter from the sides as well as the rear end. The Audi A4 is the second-best looking sedan in the segment with a wide and aggressive front-end design that rivals the C 300’s overall appeal to a great extent. The BMW 3 Series sedan has the sleekest front grille design but the new headlamp and taillamp design make the car stand out in the crowd truly.

Some of the standout exterior features are as follows:

  • All-LED headlights and taillights
  • Power-operated trunk lid

  • Chrome starburst-pattern grille(optional)
  • Rear spoiler(optional)
  • Black-painted exterior accents(optional)

The standard safety techs ion offer with the sedan includes a forward collision mitigation system and a Blind Spot Monitoring system. The optional Driver Assistance Package further adds some advanced features such as Evasive steering assist, lane departure mitigation, and Blind-spot intervention.

Some of the safety techs include:

  • Blind Spot Warning Accident Avoidance System
  • Brake Drying
  • Emergency Braking Preparation
  • Dusk Sensing Headlamps
  • Pre-Collision and Post-Collision Safety System

Mercedes Benz C-Class Sedan vs. Lexus IS 300

The Lexus IS 300 is a cheaper alternative to the Mercedes-Benz C 300 and offers an excellent value-for-money along with better reliability than the C 300. Performance-wise, the sedan falls short in front of the C 300 and its handling isn’t inspiring either but the aggressive looks and comfortable ride quality make up for the shortcomings. The IS 300 also loses out to the C 300 big time in the fuel economy department as well.

Mercedes Benz C-Class Sedan vs. Audi A4

The 2021 Audi A4 will entice the young and enthusiastic buyers out there as compared to the C 300 owing to its sportier appeal and overall better handling along with a better performance too. The A4 is more powerful and quicker than the C Class right from the base trim and offers more value for money altogether.

Audi A4

Mercedes Benz C-Class Sedan vs. BMW 3-series 330i

The BMW 3 Series gives the most intense and tough competition to the C 300 sedan. The 3 Series sedan is evenly matched to the C Class in terms of performance, handling, and overall comfort levels but feels sportier than the latter. It also triumphs over the Mercedes-Benz C Class in terms of fuel economy as well.

BMW 3-series 330i


Final Verdict

The 2021 Mercedes-Benz C Class with its refreshing design and a comfortable experience behind the wheels makes for an offer one simply can’t refuse. For the price, it offers an excellent set of interior features, a wide range of optional features, excellent comfort, and a soothing cabin design. Overall, you can opt for the C Class if you prefer comfort over sportiness or the BMW 3 Series sedan will suit you perfectly.
