Safety

The Jetta has a standard Automatic Post-Collision Braking System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Mazda 6 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Compared to metal, the Jetta’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda 6 has a metal gas tank.

Both the Jetta and the Mazda 6 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, daytime running lights, rearview cameras, available crash mitigating brakes, blind spot warning systems and rear cross-path warning.

Warranty

The Jetta comes with a full 6-year/72000-mile basic warranty, which covers the entire car. The 6’s 3-year/36,000-mile basic warranty expires 3 years and 36,000 miles sooner.

The Jetta’s corrosion warranty is 5 years longer than the Mazda 6’s (10 vs. 5 years).

There are over 12 percent more Volkswagen dealers than there are Mazda dealers, which makes it easier should you ever need service under the Jetta’s warranty.

Reliability

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Volkswagen vehicles are more reliable than Mazda vehicles. J.D. Power ranks Volkswagen 12th in reliability, above the industry average. With 28 more problems per 100 vehicles, Mazda is ranked 21st.

In heavy traffic or at stoplights the Jetta Auto’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Mazda 6 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Volkswagen Jetta uses regular unleaded gasoline. The Mazda 6 Grand Touring/Signature requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Volkswagen Jetta higher (7 out of 10) than the Mazda 6 (3 to 7). This means the Jetta produces up to 24.5 pounds less smog-producing pollutants than the Mazda 6 every 15,000 miles.

Transmission

The Jetta offers a manual transmission for better acceleration, control and fuel economy. The Mazda 6 doesn’t offer a manual transmission.

An eight-speed automatic is optional on the Volkswagen Jetta, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Mazda 6.

Brakes and Stopping

The Jetta stops shorter than the Mazda 6:

Consumer Reports

Suspension and Handling

The Jetta R-Line handles at .83 G’s, while the Mazda 6 Signature pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The Volkswagen Jetta may be more efficient, handle and accelerate better because it weighs about 550 to 600 pounds less than the Mazda 6.

The Jetta is 7.6 inches shorter than the Mazda 6, making the Jetta easier to handle, maneuver and park in tight spaces.

The design of the Volkswagen Jetta amounts to more than styling. The Jetta has an aerodynamic coefficient of drag of .27 Cd. That is lower than the Mazda 6 (.285) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Jetta get better fuel mileage.

The front grille of the Jetta uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Mazda 6 doesn’t offer active grille shutters.

Passenger Space

The Jetta has .1 inches more front headroom and .1 inches more rear headroom than the Mazda 6.

Ergonomics

The power windows standard on both the Jetta and the Mazda 6 have locks to prevent small children from operating them. When the lock on the Jetta is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Mazda 6 prevents the driver from operating the other windows just as it does the other passengers.

If the windows are left open on the Jetta SE/R-Line/SEL/SEL Premium the driver can close them all at the outside door handle. On a hot day the driver can lower the windows with the driver’s door power window switch. The driver of the Mazda 6 can only operate the windows from inside the vehicle, with the ignition on.

Recommendations

Consumer Reports® recommends both the Volkswagen Jetta and the Mazda 6, based on reliability, safety and performance.

J.D. Power and Associates rated the Jetta first among compact cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Mazda 6 isn’t in the top three in its category.

The Volkswagen Jetta outsold the Mazda 6 by almost three to one during 2018.
