Safety

The Mazda 6 has standard Whiplash Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Accord doesn’t offer a whiplash protection system.

The Mazda 6 Signature has a standard 360-degree View Monitor to allow the driver to see objects all around the vehicle on a screen. The Accord only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the Mazda 6 and the Accord 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 and rearview cameras.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mazda 6 is safer than the Honda Accord:

Consumer Reports

Suspension and Handling

The Mazda 6 Grand Touring handles at .84 G’s, while the Accord EX pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The Mazda 6 Grand Touring executes Motor Trend’s “Figure Eight” maneuver quicker than the Accord EX (27.1 seconds @ .63 average G’s vs. 27.7 seconds @ .61 average G’s).

For better maneuverability, the Mazda 6’s turning circle is 1.4 feet tighter than the Accord’s (36.7 feet vs. 38.1 feet). The Mazda 6’s turning circle is 2.7 feet tighter than the Accord Sport Manual/2.0T’s (36.7 feet vs. 39.4 feet).

Cargo Capacity

To allow full utilization of available cargo room, the Mazda 6’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. Its intrusive beam hinge reduces the Accord’s useful trunk space.

The Mazda 6’s standard folding rear seats are split to accommodate bulky cargo. The Accord LX’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

Ergonomics

The Mazda 6’s front and rear power windows all 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 Accord’s rear power window switches have to be held the entire time to open or close them fully.

To help drivers see further while navigating curves, the Mazda 6 Grand Touring Reserve/Signature has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Accord doesn’t offer cornering lights.

The Mazda 6 Grand Touring/Signature has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Accord offers an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold winter days, the Mazda 6 Grand Touring Reserve/Signature’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Accord doesn’t offer a heated steering wheel.

Economic Advantages

Insurance will cost less for the Mazda 6 owner. The Car Book by Jack Gillis rates the Mazda 6 with a number “1” insurance rate while the Accord is rated higher at a number “8” rate.

According to The Car Book by Jack Gillis, the Mazda 6 is less expensive to operate than the Accord because typical repairs cost much less on the Mazda 6 than the Accord, including $96 less for a water pump, $95 less for a muffler, $279 less for a starter, $41 less for a fuel pump, $24 less for front struts and $389 less for a power steering pump.
