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 Impala 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 Impala 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 Impala 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 and rearview cameras.

The Impala was not even a “Top Pick” for 2016.

The Mazda 6 may be more efficient, handle and accelerate better because it weighs about 200 to 300 pounds less than the Chevrolet Impala.

The Mazda 6 is 8.6 inches shorter than the Impala, making the Mazda 6 easier to handle, maneuver and park in tight spaces.

The Mazda 6 Grand Touring Reserve/Signature has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Impala doesn’t offer a heads-up display.

The Mazda 6’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Impala’s passenger windows don’t close automatically.

The Mazda 6 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Impala doesn’t offer a locking fuel door.

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 Impala’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors standard on the Mazda 6 detect other vehicles which could be blinded and automatically switch to low beams. The Impala doesn’t offer automatic dimming high beams.

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 Impala doesn’t offer cornering lights.

Both the Mazda 6 and the Impala 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 Impala.
