Safety Comparison

The Altima Sedan 3.5 SL has standard Front and Rear Sonar Sensors to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The Mazda6 doesn’t offer a front parking aid.

Compared to metal, the Altima Sedan’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda6 has a metal gas tank.

Both the Altima Sedan and the Mazda6 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, available crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems 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 Nissan Altima Sedan is safer than the Mazda6:

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 Altima Sedan its highest rating: “Top Pick Plus” for 2016, a rating granted to only 73 vehicles tested by the IIHS. The Mazda6 is not even a standard “Top Pick” for 2016.

Warranty Comparison

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

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the Altima Sedan has a standard 110-amp alternator. The Mazda6’s standard 100-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2015 Initial Quality Study of new car owners surveyed provide the statistics that show that Nissan vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks Nissan 20th in initial quality. With 2 more problems per 100 vehicles, Mazda is ranked 23rd.

J.D. Power and Associates’ 2015 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Nissan vehicles are more reliable than Mazda vehicles. J.D. Power ranks Nissan 12th in reliability, above the industry average. With 12 more problems per 100 vehicles, Mazda is ranked 15th.

Engine Comparison

The Altima Sedan 3.5’s standard 3.5 DOHC V6 produces 86 more horsepower (270 vs. 184) and 66 lbs.-ft. more torque (251 vs. 185) than the Mazda6’s 2.5 DOHC 4 cyl.

Tires and Wheels Comparison

For better traction, the Altima Sedan 2.5 SR/3.5’s tires are larger than the largest tires available on the Mazda6 (235/45R18 vs. 225/55R17).

The Altima Sedan has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Mazda6 doesn’t offer vehicle monitored tire inflation.

Suspension and Handling Comparison

The Altima Sedan 3.5 SL handles at .87 G’s, while the Mazda6 Grand Touring pulls only .83 G’s of cornering force in a Road & Track skidpad test.

The Altima Sedan 3.5 SL executes Motor Trend’s “Figure Eight” maneuver quicker than the Mazda6 Touring (27.1 seconds @ .66 average G’s vs. 27.6 seconds @ .62 average G’s).

For better maneuverability, the Altima Sedan 2.5/2.5 S’ turning circle is .6 feet tighter than the Mazda6’s (36.1 feet vs. 36.7 feet).

Chassis Comparison

To almost totally eliminate engine vibration in the passenger area, the Altima Sedan V6 has an electronically controlled liquid-filled front engine mount and conventional liquid-filled engine mounts (standard liquid front mount on other versions of the Altima Sedan). A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The Mazda6 uses conventional solid rubber engine mounts.

As tested by Car and Driver, the interior of the Altima Sedan 2.5 SV is quieter than the Mazda6 Grand Touring:

Passenger Space Comparison

The Altima Sedan has 2.2 cubic feet more passenger volume than the Mazda6 (101.9 vs. 99.7).

The Altima Sedan has 1.6 inches more front headroom, 2.8 inches more front legroom and .9 inches more rear shoulder room than the Mazda6.

Cargo Capacity Comparison

The Altima Sedan has a larger trunk than the Mazda6 (15.4 vs. 14.8 cubic feet).

A low lift-over trunk design makes loading and unloading the Altima Sedan easier. The Altima Sedan’s trunk lift-over height is 26.5 inches, while the Mazda6’s liftover is 28.5 inches.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Altima offers cargo security. The Mazda6’s non-lockable remote release defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Altima Sedan. The Mazda6 doesn’t offer locking storage for small valuables.

Ergonomics Comparison

If the front windows are left down on the Altima Sedan the driver can raise them using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Mazda6 can only operate the windows from inside the vehicle, with the ignition on.

The Altima Sedan’s speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Mazda6’s standard manually variable intermittent wipers have to be constantly adjusted.

On extremely cold Winter days, the Altima Sedan’s optional (except Base/S/SR) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Mazda6 doesn’t offer a heated steering wheel.

Recommendations Comparison

Both the Nissan Altima Sedan and Mazda6 won four awards in Kiplinger’s 2015 car issue.

Strategic Vision rates overall owner satisfaction with vehicle quality. The Nissan Altima Sedan is ranked third in the Mid-Size Car category. The Mazda6 is ranked below average.
