Safety

For enhanced safety, the front and rear seat shoulder belts of the Genesis G80 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Audi A6 doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front and rear seat shoulder belts of the Genesis G80 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Audi A6 has only front height-adjustable seat belts.

The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Automatic Emergency Braking optional in the G80 as “Superior.” The A6 scores only 3 points and is rated only “Advanced.”

To help make backing safer, the G80’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The A6 doesn’t offer a cross-path warning system.

The G80’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 A6 doesn’t offer a driver alert monitor.

The G80 has standard Connected Care, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The A6 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the G80 and the A6 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive and rear parking sensors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Genesis G80 is safer than the Audi A6:

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 headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G80 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The A6 was last qualified as only a “Top Pick” in 2017.

Warranty

The G80 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The A6’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G80 6 years and 50,000 miles longer than Audi covers the A6. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A6 ends after only 4 years or 50,000 miles.

Genesis pays for scheduled maintenance on the G80 for 3 years and 36,000 miles. Genesis will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A6.

There are over 16 percent more Genesis dealers than there are Audi dealers, which makes it easier should you ever need service under the G80’s warranty.

Reliability

J.D. Power and Associates rated the G80 second among midsize premium cars in their 2018 Initial Quality Study. The A6 isn’t in the top three.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 37 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.

Consumer Reports

Suspension and Handling

The G80 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 A6’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the G80’s wheelbase is 3.9 inches longer than on the A6 (118.5 inches vs. 114.6 inches).

For better handling and stability, the average track (width between the wheels) on the G80 is 1.1 inches wider in the rear than the track on the A6.

The G80 5.0 handles at .88 G’s, while the A6 2.0T Premium Quattro pulls only .84 G’s of cornering force in a Motor Trend skidpad test.

The G80 3.8 AWD goes through AutoWeek’s slalom 1.1 MPH faster than the A6 3.0T Premium Plus Quattro (43.1 vs. 42 MPH).

The G80 3.8 AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the A6 2.0T Premium Quattro (26.2 seconds @ .69 average G’s vs. 26.8 seconds @ .66 average G’s).

For better maneuverability, the G80’s turning circle is 2.8 feet tighter than the A6’s (36.2 feet vs. 39 feet). The G80’s turning circle is 1.6 feet tighter than the A6’s (37.4 feet vs. 39 feet).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G80 a Large car, while the A6 is rated a Mid-size.

The G80 has 10.5 cubic feet more passenger volume than the A6 (107.7 vs. 97.2).

The G80 has 3.9 inches more front headroom, 4.4 inches more front legroom, .8 inches more front shoulder room, .4 inches more rear headroom and .8 inches more rear shoulder room than the A6.

Cargo Capacity

The G80 has a much larger trunk than the A6 (15.3 vs. 14.1 cubic feet).

Ergonomics

The G80 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A6 doesn’t offer a remote starting system.

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 G80’s standard headlights were rated “Acceptable” by the IIHS, while the A6’s headlights are rated “Marginal” to “Poor.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The G80 3.8 AWD offers available headlight washers to keep headlight output high. The A6 doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the G80 has standard extendable sun visors. The A6 doesn’t offer extendable visors.

When the G80 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 A6’s mirrors don’t automatically adjust for backing.

Economic Advantages

Insurance will cost less for the G80 owner. The Car Book by Jack Gillis rates the G80 with a number “” insurance rate while the A6 is rated higher at a number “3” rate.

Recommendations

Consumer Reports® recommends both the Genesis G80 and the Audi A6, based on reliability, safety and performance.
