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’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.

A maintenance reminder system is standard on the Mazda 6 to save the owner time and money by calculating maintenance intervals for oil changes, air filter replacement and tire rotation based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Subaru doesn’t offer a maintenance reminder on the Legacy.

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 passenger windows don’t open or close automatically. With the Legacy Premium//Limited’s optional 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 Legacy’s manually variable intermittent wipers have to be constantly adjusted.

Standard air-conditioned seats in the Mazda 6 Grand Touring Reserve/Signature keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Legacy doesn’t offer air-conditioned seats.

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 Legacy 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 Legacy Premium/Sport/Limited.
