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 CLA doesn’t offer a whiplash protection system.

Both the Mazda 6 and the CLA 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 IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Mazda 6 its highest rating: “Top Pick Plus” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The CLA has not been tested, yet.

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

There are over 45 percent more Mazda dealers than there are Mercedes dealers, which makes it easier should you ever need service under the 6’s warranty.
