Year after year, our neighbors in the South Riding area compare the A-Class vs. C-Class to find the perfect luxury sedan, but which of these options is the best Mercedes-Benz class for your needs? The 2021 Mercedes-Benz A-Class and the 2021 Mercedes-Benz C-Class are both exceptional compact cars, but it’s important to consider every angle. The A-Class is more accessible, more efficient, and rich in technology, but the C-Class comes with more standard features and offers more engine options. Really, there’s no way to go wrong!

A-Class vs. C-Class: Pricing & Body Styles

In terms of pricing, the A-Class Sedan is the most accessible option. It starts with an MSRP of $33,650*, and you can add 4MATIC®® for $2,000. There’s also the AMG® A 35 4MATIC®® Sedan, which is available for a total cost of $45,850* MSRP. 

The C-Class Sedan starts at $41,600* MSRP. As with the A-Class, adding 4MATIC®® AWD to the C 300 will cost you an additional $2,000. In contrast to the smaller model, the C-Class gives you three AMG® configurations to choose from:

  • AMG® C 43 Sedan – $56,500* MSRP
  • AMG® C 63 Sedan – $68,600* MSRP
  • AMG® C 63 S Sedan – $76,200* MSRP

The 2021 Mercedes-Benz A-Class is only offered as a sedan in the U.S. market, but the 2021 Mercedes-Benz C-Class can be had as a sedan, a coupe, or a cabriolet. The C-Class Coupe starts at $47,200* MSRP, while the C-Class Cabriolet starts at $54,700* MSRP.

A-Class vs. C-Class: Performance

The A-Class is a respectable sport sedan in its own right, but the C-Class gives you many more engine options to choose from:

A-Class Engines

  • 2.0L Turbocharged i4 Engine with 188 hp and 221 lb-ft of torque
  • AMG®-Enhanced 2.0L Turbocharged i4 Engine with 302 hp and 395 lb-ft of torque

C-Class Engines

  • 2.0L Turbocharged i4 Engine with 255 hp and 273 lb-ft of torque
  • AMG®-Enhanced 3.0L V6 biturbo® Engine with 385 hp and 384 lb-ft of torque
  • Handcrafted AMG® 4.0L V8 biturbo® Engine with 469 hp and 479 lb-ft of torque
  • Handcrafted AMG® 4.0L V8 biturbo® Engine with 503 hp and 516 lb-ft of torque

If you’re on the hunt for a powerful, compact daily driver, the C-Class just might be the best Mercedes-Benz class for your needs. However, if you compare the A-Class vs. C-Class on fuel economy, you’ll see that the A-Class is more efficient. It gets up to 25 mpg city and 36 mpg highway**. The C-Class, with up to 23 mpg city and 35 mpg highway**, only just falls short of its smaller sibling’s high standard.

A-Class vs. C-Class: Interior Features & Dimensions

Both the 2021 Mercedes-Benz A-Class and the 2021 Mercedes-Benz C-Class include Apple CarPlay™, Android Auto™, remote start with the Mercedes me app, and MB-Tex® upholstery. However, there are a few differences between their feature suits that all potential buyers should be aware of:

  • A-Class Features: The 2021 A-Class includes Mercedes-Benz User Experience (MBUX), a 7-inch central touchscreen, a 7-inch digital instrument cluster, and 64-color LED ambient lighting. The advanced MBUX system gives the A-Class unique appeal.
  • C-Class Features: The 2021 C-Class includes a 10.25 inches central touchscreen, a 12.3-inch digital instrument cluster, and more. Although it lacks the standard ambient lighting of the A-Class, it more than makes up for the deficit with standard features including heated front seats, a trunk with HANDS FREE ACCESS®, and more. 

While most C-Class standard features are optional in the A-Class, some C-Class options–including Car-to-X Communication–are completely absent from the A-Class feature list. 

What’s more, the C-Class always offers more legroom and more trunk space:

  • 2nd-Row Legroom: 33.9 inches (A-Class) vs. 35.2 inches (C-Class)
  • Trunk Space: 8.6 cubic feet (A-Class) vs. 12.6 cubic feet (C-Class)
