The G70 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Mazda 6 doesn’t offer all-wheel drive.

The G70’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Mazda 6 doesn’t offer a driver alert monitor.

Both the G70 and the Mazda 6 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning 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 front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G70 its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The Mazda 6 has not been fully tested, yet.

The G70’s corrosion warranty is 2 years longer than the Mazda 6’s (7 vs. 5 years).

The battery on the G70 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the G70’s battery 20 to 30 degrees cooler, its life is increased by years. The Mazda 6’s battery is in the hot engine compartment.

J.D. Power and Associates rated the G70 first among compact premium cars in their 2019 Initial Quality Study. The Mazda 6 isn’t in the top three in its category.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 31 more problems per 100 vehicles, Mazda is ranked 12th, below the industry average.

In heavy traffic or at stoplights the G70 2.0T Automatic’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.

The G70 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 standard on the Genesis G70, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Mazda 6.

The G70’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Mazda 6 doesn’t offer launch control.

The G70’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Mazda 6 Sport’s standard 55 series tires. The G70 3.3T/2.0T Manual/Sport’s 225/40R19 front and 255/35R19 rear tires have a lower 40 series front and 35 series rear profile than the Mazda 6 Touring/Grand Touring/Signature’s 45 series tires.

For better ride, handling and brake cooling the G70 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Mazda 6 Sport.

The G70 offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Mazda 6’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the average track (width between the wheels) on the G70 is .2 inches wider in the front and 1.5 inches wider in the rear than the average track on the Mazda 6.

The G70 handles at .95 G’s, while the Mazda 6 Signature pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The G70 Standard executes Motor Trend’s “Figure Eight” maneuver 2.4 seconds quicker than the Mazda 6 Touring (25.2 seconds @ .75 average G’s vs. 27.6 seconds @ .62 average G’s).

For better maneuverability, the G70’s turning circle is .6 feet tighter than the Mazda 6’s (36.1 feet vs. 36.7 feet).

A standard locking glovebox keeps your small valuables safer in the G70. The Mazda 6 doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier when your hands are full, the G70’s trunk can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The G70 3.3T Prestige/3.3T Sport also has a standard power trunk, which opens and closes automatically by pressing a button. The Mazda 6 doesn’t offer a power or hands-free opening trunk.

The G70 uses gas struts to support the hood for easier service access. The Mazda 6 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the G70 is mounted longitudinally (North-South), instead of sideways, as in the Mazda 6. This makes it easier to service and maintain, because the accessory belts are in front.

The G70 3.3T/Elite/2.0T Manual/Prestige/Sport’s standard easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Mazda 6 doesn’t offer an easy entry system.

The power windows standard on both the G70 and the Mazda 6 have locks to prevent small children from operating them. When the lock on the G70 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.

The G70’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Mazda 6’s power lock and power mirror switches are unlit, making them difficult to find at night and operate safely.

The G70’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the Mazda 6 Grand Touring/Signature.

When the G70 3.3T/Elite/2.0T Manual/Prestige/Sport is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Mazda 6’s mirrors don’t automatically adjust for backing.

Both the G70 and the Mazda 6 offer rear vents. For greater rear passenger comfort, the G70 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Mazda 6 doesn’t offer rear air conditioning vents, only heat vents.
