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 MKZ doesn’t offer a whiplash protection system.

The Mazda 6 Signature has a standard 360-degree View Monitor to allow the driver to see objects all around the vehicle on a screen. The MKZ only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the Mazda 6 and the MKZ have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mazda 6 is safer than the Lincoln MKZ:

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, with its optional front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Mazda 6 the rating of “Top Pick” for 2019, a rating granted to only 62 vehicles tested by the IIHS. The MKZ was last qualified as a “Top Pick” in 2017.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Mazda vehicles are more reliable than Lincoln vehicles. Consumer Reports ranks Mazda third in reliability. Lincoln is ranked 20th.

An engine control system that can shut down half of the engine’s cylinders helps improve the Mazda 6 (except Turbo)’s fuel efficiency. The MKZ doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Mazda 6 uses regular unleaded gasoline (premium recommended on Mazda 6 Grand Touring/Signature for maximum performance). The MKZ with the 3.0 turbo V6 engine requires premium, which can cost 20 to 55 cents more per gallon.

The Mazda 6 has 2.4 gallons more fuel capacity than the MKZ Hybrid’s standard fuel tank (16.4 vs. 14 gallons), for longer range between fill-ups.

Brakes and Stopping

For better stopping power the Mazda 6 Touring/Signature’s front brake rotors are larger than those on the MKZ:

Consumer Reports

Suspension and Handling

The Mazda 6 has standard front and rear gas-charged shocks for better control over choppy roads. The MKZ’s suspension doesn’t offer gas-charged shocks.

The Mazda 6 Touring handles at .87 G’s, while the MKZ Hybrid pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The Mazda 6 Grand Touring executes Motor Trend’s “Figure Eight” maneuver quicker than the MKZ Premiere (27.1 seconds @ .63 average G’s vs. 27.6 seconds @ .6 average G’s).

For better maneuverability, the Mazda 6’s turning circle is 2.3 feet tighter than the MKZ’s (36.7 feet vs. 39 feet).


The Mazda 6 may be more efficient, handle and accelerate better because it weighs about 500 to 650 pounds less than the Lincoln MKZ.

As tested by Car and Driver, the interior of the Mazda 6 Touring is quieter than the MKZ AWD:




At idle

42 dB

44 dB

70 MPH Cruising

67 dB

71 dB

Passenger Space

The Mazda 6 has 3.1 cubic feet more passenger volume than the MKZ (99.7 vs. 96.6).

The Mazda 6 has .5 inches more front headroom, .5 inches more rear headroom and 1.7 inches more rear legroom than the MKZ.

Cargo Capacity

A low lift-over trunk design makes loading and unloading the Mazda 6 easier. The Mazda 6’s trunk lift-over height is 28.5 inches, while the MKZ’s liftover is 30.5 inches.


The Mazda 6 Grand Touring Reserve and Signature have 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 MKZ doesn’t offer a heads-up display.

The Mazda 6 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The MKZ doesn’t offer a locking fuel door.

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

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Mazda 6’s available headlights were rated “Acceptable” by the IIHS, while the MKZ’s headlights are rated “Marginal” to “Poor.”

Economic Advantages

Insurance will cost less for the Mazda 6 owner. The Car Book by Jack Gillis rates the Mazda 6 with a number “1” insurance rate while the MKZ is rated higher at a number “5” rate.

According to The Car Book by Jack Gillis, the Mazda 6 is less expensive to operate than the MKZ because typical repairs cost much less on the Mazda 6 than the MKZ, including $120 less for a water pump, $694 less for a muffler, $11 less for front brake pads, $37 less for a starter, $61 less for front struts, $630 less for a timing belt/chain and $724 less for a power steering pump.


Consumer Reports® recommends the Mazda 6, based on reliability, safety and performance. The Lincoln MKZ isn't recommended.

The Mazda 6 was chosen as one of Car and Driver’s “Top Ten” for 2 of the last 6 years. The MKZ has never been a Car and Driver “Top Ten” pick.

The Mazda 6 outsold the Lincoln MKZ by 56% during 2018.
