Safety

The G90’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 A8 doesn’t offer a driver alert monitor.

The G90 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 A8 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 G90 and the A8 have standard driver and passenger frontal airbags, 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 and available all wheel drive.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard 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 G90 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The A8 has not been tested, yet.

Warranty

The G90 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The A8’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G90 6 years and 50,000 miles longer than Audi covers the A8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A8 ends after only 4 years or 50,000 miles.

Genesis pays for scheduled maintenance on the G90 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 A8.

There are over 16 percent more Genesis dealers than there are Audi dealers, which makes it easier should you ever need service under the G90’s warranty.

Reliability

To reliably start during all conditions and help handle large electrical loads, the G90 has a standard 950-amp battery. The A8’s 380-amp battery isn’t as powerful.

J.D. Power and Associates rated the G90 first among large premium cars in their 2018 Initial Quality Study. The A8 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.

Engine

The G90 3.3T’s standard 3.3 turbo V6 produces 30 more horsepower (365 vs. 335) and 7 lbs.-ft. more torque (376 vs. 369) than the A8’s 3.0 turbo V6 hybrid. The G90 5.0’s standard 5.0 DOHC V8 produces 85 more horsepower (420 vs. 335) and 14 lbs.-ft. more torque (383 vs. 369) than the A8’s 3.0 turbo V6 hybrid.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Genesis G90 uses regular unleaded gasoline (premium recommended for maximum performance). The A8 requires premium, which can cost 20 to 55 cents more per gallon.

Tires and Wheels

For better traction and acceleration, the G90 has larger rear tires than the A8 (275/40R19 vs. 255/45R19).

The G90’s 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the A8’s standard 45 series tires.

Suspension and Handling

For a smoother ride and more stable handling, the G90’s wheelbase is 1.3 inches longer than on the A8 (124.4 inches vs. 123.1 inches).

For better maneuverability, the G90’s turning circle is 3 feet tighter than the A8’s (39.2 feet vs. 42.2 feet).

Chassis

The G90 is 3.8 inches shorter than the A8, making the G90 easier to handle, maneuver and park in tight spaces.

Passenger Space

The G90 has 2.8 inches more front headroom, 4.8 inches more front legroom and .3 inches more rear shoulder room than the A8.

Cargo Capacity

The G90 has a much larger trunk than the A8 (15.7 vs. 12.5 cubic feet).

Ergonomics

The G90 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 A8 doesn’t offer a remote starting system.

The G90 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the A8.

Model Availability

The G90 is available in both rear-wheel drive and all-wheel drive configurations. The A8 doesn’t offer a two-wheel drive configuration.
