2021 Honda Civic vs Mazda3: Fuel Efficiency Specs

The Honda Civic offers a continuously variable transmission (CVT). The drivetrain is known for being smoother, quieter, and more fuel-efficient, which is how the 2021 Honda Civic achieves a maximum EPA-estimated fuel economy rating of 32 city/42 highway MPG on its EX and EX-L trims.1

This transmission is available in all Civic trims:

  • LX
  • Sport
  • EX

Civic vs Mazda3 Interior Dimensions

A worthwhile sedan has to be just as comfortable as it is efficient. You’ll find plenty of room in both of these models. However, in this respect, passengers might prefer the 2021 Civic over the 2021 Mazda3.

The Honda Civic’s cabin offers a total of 97.8 cubic feet of passenger volume. This is a clear improvement over the Mazda3, which falls short at 92.8 cubic feet of occupant room.
