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 Sonata doesn’t offer a whiplash protection system.

Both the Mazda 6 and the Sonata have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 and available around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Mazda 6 the rating of “Top Pick” for 2017, a rating granted to only 169 vehicles tested by the IIHS.

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 Sonata’s standard passenger windows don’t open or close automatically. With the Sonata SEL/SEL Plus/Limited’s power windows, only the front windows open or close automatically.

The Mazda 6’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Sonata’s manually variable intermittent wipers have to be constantly adjusted.

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 Sonata offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Mazda 6 and the Sonata offer available heated front seats. The Mazda 6 Grand Touring Reserve/Signature also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Sonata.

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 Sonata doesn’t offer a heated steering wheel.

The Mazda 6 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Sonata SEL/SEL Plus/Limited.
