Both the S8 and G80 have child safety locks to prevent children from opening the rear doors. The S8 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G80’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The S8 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The G80 doesn’t offer front seat center airbags.

The S8 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 S8. But it costs extra on the G80.

A passive infrared night vision system optional on the S8 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 and even aims one of the vehicle’s headlights in the direction of the person or object. The G80 doesn’t offer a night vision system.

Both the S8 and the G80 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front 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, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.

The Audi S8 weighs 586 to 1107 pounds more than the Genesis G80. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The S8’s 4.0 turbo V8 hybrid produces 252 more horsepower (563 vs. 311) and 297 lbs.-ft. more torque (590 vs. 293) than the G80 3.8’s standard 3.8 DOHC V6. The S8’s 4.0 turbo V8 hybrid produces 198 more horsepower (563 vs. 365) and 214 lbs.-ft. more torque (590 vs. 376) than the G80 3.3T Sport’s standard 3.3 turbo V6. The S8’s 4.0 turbo V8 hybrid produces 143 more horsepower (563 vs. 420) and 207 lbs.-ft. more torque (590 vs. 383) than the G80 5.0’s standard 5.0 DOHC V8.

Regenerative brakes improve the S8’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 S8’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.

The S8 has 1.4 gallons more fuel capacity than the G80 (21.7 vs. 20.3 gallons), for longer range between fill-ups.

The S8’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.

The S8 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The G80 doesn’t offer ceramic brake rotors.

Tires and Wheels

For better traction, the S8 has larger tires than the G80 (265/40R20 vs. 245/45R18). The S8’s tires are larger than the largest tires available on the G80 (265/40R20 vs. 245/40R19).

The S8’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the G80 3.8’s standard 45 series tires. The S8’s optional tires have a lower 35 series profile than the G80’s optional 40 series front tires.

For better ride, handling and brake cooling the S8 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the G80 3.8. The S8’s optional 21-inch wheels are larger than the 19-inch wheels optional on the G80.

Suspension and Handling

The front and rear suspension of the S8 uses air springs for a smoother, controlled ride than the G80, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The S8 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The S8’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The G80 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the S8’s wheelbase is 4.7 inches longer than on the G80 (123.2 inches vs. 118.5 inches).

The S8 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The G80 doesn’t offer active noise cancellation.

The S8 has .8 inches more front shoulder room, .3 inches more rear headroom, 9.3 inches more rear legroom and .5 inches more rear shoulder room than the G80.

For enhanced passenger comfort on long trips the S8’s available rear seats recline. The G80’s rear seats don’t recline.

Unlike the driver-only memory system in the G80, the S8 has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

If the windows are left open on the S8 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the G80 can only operate the windows from inside the vehicle, with the ignition on.

The S8 has standard front air-conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

The S8 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 G80.

The S8 has standard massaging front and optional massaging rear seats. Massaging seats aren’t available in the G80.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi S8 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the G80.

The S8 offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The G80 doesn’t offer a house-current electrical outlet.
