Safety

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 A4 has only front height-adjustable seat belts.

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 A4 doesn’t offer a driver alert monitor.

Both the G80 and the A4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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, rearview cameras, available all wheel drive and rear parking sensors.

The Genesis G80 weighs 613 to 1266 pounds more than the Audi A4. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

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 A4 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 A4’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 A4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A4 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 A4.

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

To reliably start during all conditions and help handle large electrical loads, the G80 has a standard 740-amp battery. The A4’s 420-amp battery isn’t as powerful.

J.D. Power and Associates rated the G80 second among midsize premium cars in their 2018 Initial Quality Study. The A4 isn’t in the top three in its category.

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

Tires and Wheels

For better traction, the G80 has larger standard tires than the A4 (245/45R18 vs. 225/50R17).

The G80 3.8’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 A4’s standard 50 series tires.

For better ride, handling and brake cooling the G80 3.8 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the A4.

Suspension and Handling

For a smoother ride and more stable handling, the G80’s wheelbase is 8.5 inches longer than on the A4 (118.5 inches vs. 110 inches).

For better handling and stability, the average track (width between the wheels) on the G80 is 2 inches wider in the front and 3.6 inches wider in the rear than the track on the A4.

The G80 5.0 handles at .88 G’s, while the A4 Premium pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

The G80 3.8 AWD executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the A4 Premium (26.2 seconds @ .69 average G’s vs. 27.2 seconds @ .64 average G’s).

For better maneuverability, the G80’s turning circle is 1.9 feet tighter than the A4’s (36.2 feet vs. 38.1 feet). The G80’s turning circle is .7 feet tighter than the A4’s (37.4 feet vs. 38.1 feet).

Chassis

As tested by Car and Driver while at idle, the interior of the G80 5.0 is quieter than the A4 Prestige Quattro (39 vs. 42 dB).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G80 a Large car, while the A4 is rated a Compact.

The G80 has 15.7 cubic feet more passenger volume than the A4 (107.7 vs. 92).

The G80 has 2.2 inches more front headroom, 4.4 inches more front legroom, 2.4 inches more front shoulder room, .8 inches more rear headroom and 2.6 inches more rear shoulder room than the A4.

Cargo Capacity

The G80 has a much larger trunk than the A4 (15.3 vs. 13 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 A4 doesn’t offer a remote starting system.

The G80’s optional 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 A4 doesn’t offer an easy entry system.

The A4’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The G80’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

A power rear sunshade is optional in the G80 to help block heat and glare for the rear passengers. The A4 doesn’t offer a rear sunshade.

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 A4’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 A4 is rated higher at a number “5” rate.
