There are many luxury sedans available to tackle Princeton roads, however, only a few stand out among the crowd. Arguably two of the most popular options for many Hamilton shoppers to compare is the C-Class vs. 3 Series. The new Mercedes-Benz C-Class and BMW 3 Series exude a commanding presence on the road. While both vehicles are impressive, we believe there is only one true winner in this comparison. Today at Mercedes-Benz of Princeton, we’ll take a look at the 2021 Mercedes-Benz C-Class vs. 2021 BMW 3 Series performance and features to help you decide on your next luxury sedan. We’ll also briefly discuss the Audi A4 vs. BMW 3 Series vs. Mercedes-Benz C-Class and how they compare to each other.

C-Class vs. 3 Series – Performance

When you’re in the market for a new luxury sedan, one of the most important factors is its performance capabilities. Let’s take a look at the standard and available powertrains and specifications of the 2021 C-Class vs. 2021 3 Series and see which one comes out on top:


  • Standard 2.0L turbocharged 4-cylinder engine producing 255 hp and 273 lb-ft of torque.
  • Standard 9-speed automatic transmission.
  • Available handcrafted AMG® 4.0L V8 Biturbo engine producing 503 hp and 516 lb-ft of torque.
  • The fastest C-Class configuration can go from 0-60 mph in 3.8 seconds and features mpg figures of 17 mpg city/26 mpg highway.


  • Standard 2.0L turbocharged 4-cylinder engine producing 255 hp and 294 lb-ft of torque.
  • Standard 8-speed automatic transmission.
  • Available 3.0L TwinPower turbocharged inline 6-cylinder engine producing 503 hp and 479 lb-ft of torque.
  • The fastest 3-Series configuration can go from 0-60 mph in 3.8 seconds and features mpg figures of 16 mpg city/23 mpg highway.

From the get go, you’ll notice that both sedans offer similar performance in the base configuration but as you move up to the highest trim there is no real comparison. The upgraded engine in the AMG® C 63 S Sedan is absolutely on a different level compared to the upgraded engine in the BMW M3 Competition Sedan. Not only does the fastest C-Class configuration offer more power and a V8 engine, it also features better fuel economy as well.

What about the Audi A4 vs. BMW 3 Series vs. Mercedes-Benz C-Class? The Audi A4 offers a standard 2.0L 4-cylinder engine producing only 201 hp and 236 lb-ft of torque which is no comparison to the standard engine in the C-Class. The bottom line is that the Mercedes-Benz C-Class is the true winner when it comes to engines and performance.

C-Class vs. 3 Series – Features

The 2021 C-Class and 2021 3 Series both offer many luxury features to keep Mercer County drivers comfortable when taking on their commute and adventures. Both models provide features such as:

  • Selectable drive modes
  • Adaptive suspension
  • Premium interior materials
  • Driver assistance features
  • LED lighting
  • And many more!

While impressive, the Mercedes-Benz C-Class stands out by also offering these features:

  • ATTENTION ASSIST® – ATTENTION ASSIST® monitors your driving characteristics and lets you know when you need to take a break while driving. This handy innovation is exclusive to Mercedes-Benz and is a fantastic safety feature.
  • HANDS-FREE ACCESS® – HANDS-FREE ACCESS® allows you to open your trunk when your hands are full. We take one less thing off your hands by offering this feature as standard on the 2021 C-Class.

While the competition with the C-Class vs. 3 Series is fierce, the C-Class edges out its competitor by offering Mercedes-Benz exclusive features, some of which come as standard. There are many more reasons why we believe the C-Class is the winner when it comes to convenience technology, and we recommend visiting your nearest Mercedes-Benz dealership to schedule a test drive and experience it for yourself. Be sure to compare the 2021 Mercedes-Benz C-Class and Mercedes-Benz E-Class while you’re here!
