For enhanced safety, the front seat shoulder belts of the Mazda 6 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes A-Class doesn’t offer height-adjustable seat belts.

To help make backing safer, the Mazda 6’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The A-Class doesn’t offer a cross-path warning system.

Both the Mazda 6 and the A-Class have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Mazda 6 the rating of “Top Pick” for 2017, a rating granted to only 169 vehicles tested by the IIHS. The A-Class has not been tested, yet.

Mazda’s powertrain warranty covers the 6 1 year and 10,000 miles longer than Mercedes covers the A-Class. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the A-Class ends after only 4 years or 50,000 miles.

There are over 52 percent more Mazda dealers than there are Mercedes dealers, which makes it much easier should you ever need service under the 6’s warranty.

On the EPA test cycle the Mazda6 with its standard engine gets better fuel mileage than the A 220 FWD (26 city/35 hwy vs. 24 city/35 hwy).

For better traction, the Mazda 6 has larger tires than the A-Class (225/55R17 vs. 205/55R17).

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 A-Class’ 55 series tires.

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 A-Class; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.
