The Civic has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Mazda 3 doesn’t offer a cap-less fueling system.

Tires and Wheels Comparison

For better traction, the Civic has larger standard tires than the Mazda 3 (215/55R16 vs. 205/60R16). The Civic Hatchback Sport/Sport Touring’s tires are larger than the largest tires available on the Mazda 3 (235/40R18 vs. 215/45R18).

The Civic LX/LX-P/EX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Mazda 3 Sport’s standard 60 series tires. The Civic Hatchback Sport/Sport Touring’s tires have a lower 40 series profile than the Mazda 3 Touring/Grand Touring’s 45 series tires.

Suspension and Handling Comparison

The Civic’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Mazda 3 doesn’t offer drift compensation steering.

The Civic Sport Hatchback handles at .93 G’s, while the Mazda 3 Touring 4-Door pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

As tested by Car and Driver while at idle, the interior of the Civic Touring Sedan is quieter than the Mazda 3 4-Door (38 vs. 39 dB).

Passenger Space Comparison

Because it has more passenger and cargo room, the EPA rates the Civic Sedan a Mid-size car, while the Mazda 3 4-Door is rated a Compact.

The Civic Sedan has .7 inches more front headroom, .1 inches more front legroom, 1.6 inches more rear legroom and .6 inches more rear shoulder room than the Mazda 3 4-Door.

Cargo Capacity Comparison

The Civic Sedan has a much larger trunk than the Mazda 3 4-Door (15.1 vs. 12.4 cubic feet).

The Civic Hatchback with its rear seat up has a much larger trunk than the Mazda 3 5-Door with its rear seat up (25.7 vs. 20.2 cubic feet).

Ergonomics Comparison

The Civic’s front power windows open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Mazda 3’s passenger windows don’t open or close automatically.

If the windows are left down on the Civic the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Mazda 3 can only operate the windows from inside the vehicle, with the ignition on.

The Civic has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The Mazda 3 only offers an automatic headlight on/off feature as an extra cost option.

Both the Civic and the Mazda 3 offer available heated front seats. The Civic Touring Sedan/Sport Touring also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Mazda 3.

The Civic (except LX/EX/EX-T)’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Mazda 3’s available navigation system doesn’t offer real-time traffic updates.

Economic Advantages Comparison

The Civic will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Civic will retain 47.26% to 50.4% of its original price after five years, while the Mazda 3 only retains 40.72% to 46.47%.

According to The Car Book by Jack Gillis, the Civic is less expensive to operate than the Mazda 3 because it costs $369 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost less on the Civic than the Mazda 3, including $39 less for a water pump, $124 less for an alternator, $35 less for front brake pads, $88 less for fuel injection and $138 less for a fuel pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Honda Civic will be $960 to $1406 less than for the Mazda 3.

Recommendations Comparison

Car and Driver performed a comparison test in its April 2017 issue and they ranked the Honda Civic Sport Hatchback first. They ranked the Mazda 3 5-Door third.

J.D. Power and Associates rated the Civic second among compact cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Mazda 3 isn’t in the top three.

The Honda Civic outsold the Mazda 3 by almost four to one during 2016.
