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.

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 Sonata only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the Mazda 6 and the Sonata 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, daytime running lights, blind spot warning systems, rearview cameras and rear cross-path warning.

For better traction, the Mazda 6 has larger tires than the Sonata (225/55R17 vs. 205/65R16).

The Mazda 6 Sport’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 Sonata SE/Eco’s standard 65 series tires.

For better ride, handling and brake cooling the Mazda 6 Sport has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Sonata SE/Eco. The Mazda 6 Touring/Grand Touring/Signature’s 19-inch wheels are larger than the 18-inch wheels on the Sonata 2.0T.
