Safety

The G90 has standard Anti-Whiplash Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Anti-Whiplash Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. The A6 doesn’t offer a whiplash protection system.

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 A6 doesn’t offer a driver alert monitor.

Both the G90 and the A6 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 and available all wheel drive.

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 G90 its highest rating: “Top Pick Plus” for 2019, a rating granted to only 36 vehicles tested by the IIHS. The A6 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 A6’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 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 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 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 G90’s warranty.

Reliability

J.D. Power and Associates rated the G90 first among large premium cars in their 2018 Initial Quality Study. The A6 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 A6’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 A6’s 3.0 turbo V6 hybrid.

Fuel Economy and Range

The G90 has 2.6 gallons more fuel capacity than the A6 (21.9 vs. 19.3 gallons), for longer range between fill-ups.

Transmission

An eight-speed automatic is standard on the Genesis G90, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A6.

Brakes and Stopping

For better stopping power the G90’s brake rotors are larger than those on the A6:

Tires and Wheels

For better traction and acceleration, the G90 has larger rear tires than the A6 (275/40R19 vs. 245/45R19). The G90’s rear tires are larger than the largest rear tires available on the A6 (275/40R19 vs. 255/40R20).

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 A6’s standard 45 series tires.

Suspension and Handling

For a smoother ride and more stable handling, the G90’s wheelbase is 9.3 inches longer than on the A6 (124.4 inches vs. 115.1 inches).

The G90’s front to rear weight distribution is more even (51% to 49%) than the A6’s (55% to 45%). This gives the G90 more stable handling and braking.

Chassis

The design of the Genesis G90 amounts to more than styling. The G90 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the A6 (.29) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G90 get better fuel mileage.

Passenger Space

The G90 has 3.1 inches more front headroom, 5 inches more front legroom, 1.3 inches more front shoulder room, .4 inches more rear legroom and 1.4 inches more rear shoulder room than the A6.

For enhanced passenger comfort on long trips the G90 5.0’s rear seats recline. The A6’s rear seats don’t recline.

Cargo Capacity

The G90 has a much larger trunk than the A6 (15.7 vs. 13.7 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 A6 doesn’t offer a remote starting system.

The G90 has standard front air conditioned seats and the G90 5.0 also has them in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The A6 doesn’t offer air-conditioned seats in the rear.

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 A6.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Genesis G90 has a standard wireless phone charging system (Qi) for the front seat. Wireless charging costs extra on the A6.

Model Availability
