For better traction, the Mazda 6 has larger tires than the Optima Hybrid (225/55R17 vs. 215/55R17).

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 Optima Hybrid’s 55 series tires.

For better ride, handling and brake cooling the Mazda 6 Touring/Grand Touring/Signature has standard 19-inch wheels. The Optima Hybrid’s largest wheels are only 17-inches.

The Mazda 6 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Optima Hybrid; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The Mazda 6 has a much larger trunk than the Optima Hybrid (14.7 vs. 13.4 cubic feet).

To allow full utilization of available cargo room, the Mazda 6’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The Optima Hybrid’s useful trunk space is reduced by its intrusive beam hinge.

The Mazda 6’s standard rear seats fold to accommodate long and bulky cargo. The Optima Hybrid Premium doesn’t offer folding rear seats, only a ski pass-through.

The Mazda 6 offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The Optima Hybrid doesn’t offer a remote starting system.

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

The Mazda 6’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Optima Hybrid has an automatic rear view mirror, but its side mirrors don’t dim.

Both the Mazda 6 and the Optima Hybrid 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 Optima Hybrid.
