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

For better ride, handling and brake cooling the Mazda 6 Touring/Grand Touring/Signature has standard 19-inch wheels. The Legacy’s largest wheels are only 18-inches.

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 Legacy doesn’t offer a heads-up display.

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 Legacy’s standard rear power window switches have to be held the entire time to open or close them fully.

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

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

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 Legacy Premium/Sport/Limited/Touring.
