Mercedes-Benz C-Class vs BMW 3 Series: Trim Levels & Performance

Let's begin by looking at the trim level, engine, and performance options for each model. The Mercedes-Benz C-Class offers drivers the choice between the following:

  • C 300
  • C 300 4MATIC®

The 2020 Mercedes-Benz C-Class models feature a standard 255-horsepower 2.0L turbo engine delivering 273 lb-ft of torque. Performance-wise, the difference is that the C 300 4MATIC sedan model features the 4MATIC® all-wheel-drive system.

In comparison, the 2021 BMW 3 Series offers quite a few more options, including a plug-in hybrid model. Car-shoppers can select from the following:

  • 330i
  • 330i xDrive
  • M340i
  • M340i xDrive
  • 330e
  • 330e xDrive

The standard BMW 3 Series model also comes with a 255-horsepower 2.0L turbo engine, however, the M340i xDrive features a mighty 335-horsepower 3.0L engine with eBoost 48V mild hybrid technology. In terms of trim levels and performance, drivers will ultimately find the 2021 BMW 3 Series provides a wider variety.
