Using vehicle speed sensors and seat sensors, smart airbags in the Accord deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Accord’s side airbags will shut off if a child is leaning against the door. The Mazda 6’s airbags don’t have smart features and will always deploy full force.

The Accord’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Mazda 6 doesn’t offer a driver alert monitor.

Compared to metal, the Accord’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda 6 has a metal gas tank.

Both the Accord and the Mazda 6 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.

To lower fuel costs and make buying fuel easier, the Honda Accord uses regular unleaded gasoline. The Mazda 6 Grand Touring/Signature requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The Accord 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 6 doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Honda Accord higher (6 to 7 out of 10) than the Mazda 6 (3 to 7). This means the Accord produces up to 24.5 pounds less smog-producing pollutants than the Mazda 6 every 15,000 miles.

The Accord offers a manual transmission for better acceleration, control and fuel economy. The Mazda 6 doesn’t offer a manual transmission.

A 10-speed automatic is standard on the Honda Accord 2.0 turbo 4-cylinder, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Mazda 6.

The Accord has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Mazda 6 doesn’t offer a CVT.

For better traction, the Accord Sport/Touring’s tires are larger than the largest tires available on the Mazda 6 (235/40R19 vs. 225/55R17).

The Accord’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Mazda 6 Sport’s standard 55 series tires. The Accord Sport/Touring’s tires have a lower 40 series profile than the Mazda 6 Touring/Grand Touring/Signature’s 45 series tires.

The Accord offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Mazda 6’s suspension doesn’t offer adjustable shock absorbers.

The Accord’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 6 doesn’t offer drift compensation steering.

For better handling and stability, the average track (width between the wheels) on the Accord is .2 inches wider in the front and 1 inch wider in the rear than the average track on the Mazda 6.

The Accord Sport handles at .90 G’s, while the Mazda 6 Signature pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The Accord Sport executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the Mazda 6 Touring (26.4 seconds @ .67 average G’s vs. 27.6 seconds @ .62 average G’s).

The Honda Accord may be more efficient, handle and accelerate better because it weighs about 150 to 300 pounds less than the Mazda 6.

The front grille of the Accord EX 1.5T/EX-L 1.5T uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Mazda 6 doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the Accord EX-L is quieter than the Mazda 6 Grand Touring:

Because it has more passenger and cargo room, the EPA rates the Accord a Large car, while the Mazda 6 is rated a Mid-size.

The Accord has 5.9 cubic feet more passenger volume than the Mazda 6 (105.6 vs. 99.7).

The Accord has 1.1 inches more front headroom, .1 inches more front legroom, 1.8 inches more front hip room, 2.4 inches more front shoulder room, .2 inches more rear headroom, 1.7 inches more rear legroom, 1.5 inches more rear hip room and 1.4 inches more rear shoulder room than the Mazda 6.

The Accord has a much larger trunk than the Mazda 6 (16.7 vs. 14.7 cubic feet).

A low lift-over trunk design makes loading and unloading the Accord easier. The Accord’s trunk lift-over height is 26.5 inches, while the Mazda 6’s liftover is 28.5 inches.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Accord offers cargo security. The Mazda 6’s non-lockable remote release defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Accord. The Mazda 6 doesn’t offer locking storage for small valuables.

The Accord 2.0L Turbo offers up to a 1000 lbs. towing capacity. The Mazda 6 has no towing capacity.

The Accord with a manual transmission can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Accord can be unhitched and driven around locally. The Mazda 6 can’t be towed flat on the ground.

The Accord EX-L/Touring’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Mazda 6 doesn’t offer an easy entry system.

If the windows are left open on the Accord the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Mazda 6 can only operate the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the Accord’s headlight performance “Very Good,” a higher rating than the Mazda 6’s headlights, which were rated “Good.”

When the Accord Touring is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Mazda 6’s mirrors don’t automatically adjust for backing.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Honda Accord Touring has a standard wireless phone charging system (Qi) in the center console. The Mazda 6 doesn’t offer wireless personal charging.
