Safety

The A5 Sportback has standard Secondary Collision Brake Assist, which automatically apply 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 A5 Sportback. But it costs extra on the G80.

The A5 Sportback Prestige has a standard Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The G80 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Compared to metal, the A5 Sportback’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Genesis G80 has a metal gas tank.

Both the A5 Sportback and the G80 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 lane departure warning systems, blind spot warning systems and rear cross-path warning.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Audi A5 Sportback is safer than the Genesis G80:

Warranty

The A5 Sportback’s corrosion warranty is 5 years longer than the G80’s (12 vs. 7 years).

Reliability

The Audi A5 Sportback’s engine uses a cast iron block for durability, while the G80’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Audi 5 places higher in reliability than Genesis.

Fuel Economy and Range

On the EPA test cycle the A5 Sportback gets better fuel mileage than the G80 3.8 AWD (23 city/34 hwy vs. 18 city/24 hwy).

Regenerative brakes improve the A5 Sportback’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 A5 Sportback’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.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A5 Sportback higher (5 out of 10) than the Genesis G80 (3 to 5). This means the A5 Sportback produces up to 16.5 pounds less smog-producing pollutants than the G80 every 15,000 miles.

Transmission

The A5 Sportback offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The G80 doesn’t offer an SMG or a conventional manual transmission.

The A5 Sportback’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The G80 doesn’t offer launch control.

Brakes and Stopping

The A5 Sportback’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 A5 Sportback stops much shorter than the G80:

Car and Driver

Tires and Wheels

For better traction, the A5 Sportback’s optional tires are larger than the largest tires available on the G80 (255/35R19 vs. 245/40R19).

The A5 Sportback’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 A5 Sportback’s optional tires have a lower 35 series profile than the G80’s optional 40 series front tires.

Suspension and Handling

The A5 Sportback Prestige handles at .94 G’s, while the G80 AWD pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The Audi A5 Sportback may be more efficient, handle and accelerate better because it weighs about 450 to 1000 pounds less than the Genesis G80.

The A5 Sportback is 10.2 inches shorter than the G80, making the A5 Sportback easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver, the interior of the A5 Sportback Prestige is quieter than the G80 5.0:

Cargo Capacity

The A5 Sportback has a much larger trunk than the G80 (21.8 vs. 15.3 cubic feet).

The A5 Sportback’s standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Ergonomics

If the windows are left open on the A5 Sportback the driver can close them all at the outside door handle. On a hot day the driver can also lower the windows the same way. The driver of the G80 can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the A5 Sportback to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G80 doesn’t offer heated windshield washer nozzles.

Optional air-conditioned seats in the A5 Sportback Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

The A5 Sportback Prestige’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The G80 doesn’t offer an automated parking system.

Model Availability

The Audi A5 comes in coupe, convertible and four door hatchback bodystyles; the Genesis G80 isn’t available as a coupe or convertible.

Economic Advantages

Insurance will cost less for the A5 Sportback owner. The Complete Car Cost Guide estimates that insurance for the A5 Sportback will cost $305 less than the G80 over a five-year period.

The A5 Sportback will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the A5 Sportback will retain 44.13% to 47.54% of its original price after five years, while the G80 only retains 40.26% to 44.12%.

Recommendations

The Audi A5/S5 outsold the Genesis G80 by almost three to one during the 2018 model year.
