The Audi A5 Sportback has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The G80 doesn’t offer a front passenger side knee airbag.

The A5 Sportback 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.

When descending a steep, off-road slope, the A5 Sportback’s standard Hill Descent Control allows you to creep down safely. The G80 doesn’t offer Hill Descent Control.

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, all wheel drive, 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, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Audi A5 Sportback is safer than the Genesis G80:

	A5 Sportback	G80
	Driver
STARS	4 Stars	4 Stars
HIC	164	202
Neck Injury Risk	26%	28%
Leg Forces (l/r)	431/395 lbs.	296/772 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

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

	A5 Sportback	G80
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	13 inches
Hip Force	666 lbs.	676 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Warranty

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

There are over 26 percent more Audi dealers than there are Genesis dealers, which makes it easier should you ever need service under the A5 Sportback’s warranty.

Reliability

The Audi A5 Sportback’s engines use 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.

Fuel Economy and Range

On the EPA test cycle the A5 Sportback gets better mileage than the G80:

			MPG
A5 Sportback
	AWD	40 TFSI 2.0 turbo 4-cyl. Hybrid	26 city/36 hwy
		45 TFSI 2.0 turbo 4-cyl. Hybrid	23 city/32 hwy
G80
	AWD	2.5 turbo 4-cyl.	20 city/29 hwy
		3.5 turbo V6	16 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.

To lower fuel costs and make buying fuel easier, the Audi A5 Sportback uses regular unleaded gasoline (premium recommended for maximum performance). The G80 2.5T requires premium, which can cost on average about 84.9 cents more per gallon.

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.

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 2.5T are solid, not vented.

The A5 Sportback stops much shorter than the G80:

	A5 Sportback	G80
70 to 0 MPH	159 feet	174 feet	Car and Driver

Tires and Wheels

For better traction, the A5 Sportback 45 TFSI’s optional tires are larger than the largest tires available on the G80 (265/30R20 vs. 245/45R19).

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 2.5T Standard’s standard 50 series tires. The A5 Sportback 45 TFSI’s optional tires have a lower 30 series profile than the G80 Sport Prestige’s 40 series front and 35 series rear tires.

Suspension and Handling

The A5 Sportback Prestige handles at .94 G’s, while the G80 pulls only .87 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 400 to 700 pounds less than the Genesis G80.

The A5 Sportback 45 TFSI is 9.5 inches shorter than the G80, making the A5 Sportback easier to handle, maneuver and park in tight spaces.

Cargo Capacity

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.

Towing

The A5 Sportback has a 3500 lbs. towing capacity. The G80 has no towing capacity.

Ergonomics

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.

Laser headlights, standard on the A5 Sportback Prestige, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the G80’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The A5 Sportback’s headlights were rated “Good” to “Acceptable” by the IIHS, while the G80’s headlights are rated “Acceptable.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A5 Sportback has standard headlight washers to keep headlight output high. The G80 doesn’t offer headlight washers.

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 $2240 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 47.83% to 49.06% of its original price after five years, while the G80 only retains 46.32% to 47.24%.

Recommendations

The Audi A5/S5 outsold the Genesis G80 by over four to one during 2023.
