Safety

The A6 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G80 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A6. But it costs extra on the G80.

A passive infrared night vision system optional on the A6 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The G80 doesn’t offer a night vision system.

The A6 offers an optional Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The G80 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 A6 and the G80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.

Warranty

The A6’s corrosion warranty is 5 years longer than the G80’s (12 vs. 7 years).

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Audi 5 places higher in reliability than Genesis.

Engine

The A6’s 3.0 turbo V6 hybrid produces 24 more horsepower (335 vs. 311) and 76 lbs.-ft. more torque (369 vs. 293) than the G80 3.8’s standard 3.8 DOHC V6.

Fuel Economy and Range

On the EPA test cycle the A6 3.0T gets better fuel mileage than the G80 3.8 AWD (22 city/29 hwy vs. 18 city/24 hwy). The A6 3.0T gets better fuel mileage than the G80 3.3T AWD (22 city/29 hwy vs. 17 city/24 hwy).

Regenerative brakes improve the A6’s fuel efficiency by converting inertia back into energy instead of wasting it. The G80 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the A6’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 G80 doesn’t offer an automatic engine start/stop system.

Transmission

The A6 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The G80 doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

The A6’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G80 3.8 are solid, not vented.

Tires and Wheels

For better traction, the A6’s optional tires are larger than the largest tires available on the G80 (255/40R20 vs. 245/40R19).

The A6 Prestige’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the G80’s optional 40 series front tires.

For better ride, handling and brake cooling the A6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the G80 3.8. The A6 Prestige’s optional 21-inch wheels are larger than the 19-inch wheels optional on the G80.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the A6 is 1.3 inches wider in the front than the average track on the G80.

Cargo Capacity

The A6’s standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Ergonomics

The A6’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the G80.

Optional air conditioned seats in the A6 keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

Recommendations

The Audi A6/S6 outsold the Genesis G80 by 108 units during 2017.
