The Audi A4 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 A4 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 A4. But it costs extra on the G80.

When descending a steep, off-road slope, the A4’s standard Hill Descent Control allows you to creep down safely. The G80 doesn’t offer Hill Descent Control.

Compared to metal, the A4’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 A4 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, 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 A4 is safer than the Genesis G80:

	A4	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 A4 is safer than the Genesis G80:

	A4	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.

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 A4 its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 135 vehicles tested by the IIHS. The G80 is only a standard “Top Safety Pick” for 2019.

Warranty

The A4’s corrosion warranty is 5 years longer than the G80’s (12 vs. 7 years).

Reliability

The Audi A4’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.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Audi vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Audi 6 places higher in reliability than Genesis.

Engine

As tested in Car and Driver the A4 45 TFSI is faster than the G80 3.5T 3.5 turbo V6:

	A4	G80
Zero to 60 MPH	4.8 sec	4.9 sec
5 to 60 MPH Rolling Start	5.6 sec	5.7 sec

Fuel Economy and Range

On the EPA test cycle the A4 gets better mileage than the G80:

			MPG
A4
	AWD	40 TFSI 2.0 turbo 4-cyl. Hybrid	26 city/35 hwy
		45 TFSI 2.0 turbo 4-cyl. Hybrid	24 city/32 hwy
G80
	RWD	2.5 turbo 4-cyl.	22 city/32 hwy
	AWD	2.5 turbo 4-cyl.	22 city/30 hwy
		3.5 turbo V6	16 city/25 hwy

To lower fuel costs and make buying fuel easier, the Audi A4 uses regular unleaded gasoline (premium recommended for maximum performance). The G80 2.5T requires premium, which can cost on average about 82.8 cents more per gallon.

Transmission

The A4 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 A4’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 A4 stops much shorter than the G80:

	A4	G80
70 to 0 MPH	149 feet	174 feet	Car and Driver
60 to 0 MPH	105 feet	124 feet	Motor Trend

Tires and Wheels

The A4’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the G80 3.5T Sport Prestige’s optional 40 series front tires.

Suspension and Handling

The A4 Premium Plus handles at .97 G’s, while the G80 pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

The A4 Premium Plus executes Motor Trend’s “Figure Eight” maneuver quicker than the G80 AWD (25.3 seconds @ .74 average G’s vs. 26.2 seconds @ .68 average G’s).

Chassis

The Audi A4 may be more efficient, handle and accelerate better because it weighs about 550 to 850 pounds less than the Genesis G80.

The A4 is 9.2 inches shorter than the G80, making the A4 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

A low lift-over trunk design makes loading and unloading the A4 easier. The A4’s trunk lift-over height is 26.9 inches, while the G80’s liftover is 28.8 inches.

The A4’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 A4 has a 3968 lbs. towing capacity. The G80 has no towing capacity.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than Genesis. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 29% lower rating, Genesis is ranked 23rd.

Ergonomics

Heated windshield washer nozzles are standard on the A4 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.

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 A4’s available headlights were rated “Good” 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 A4 Prestige has standard headlight washers to keep headlight output high. The G80 doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the A4 has standard cornering lights to illuminate around corners when the turn signals are activated. The G80 doesn’t offer cornering lights.

Economic Advantages

Insurance will cost less for the A4 owner. The Complete Car Cost Guide estimates that insurance for the A4 will cost $2105 less than the G80 over a five-year period.

The A4 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the A4 will retain 48.96% to 51.87% of its original price after five years, while the G80 only retains 46.32% to 47.24%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi A4 will be $10086 to $18040 less than for the Genesis G80.

Recommendations

Consumer Reports® recommends both the Audi A4 and the Genesis G80, based on reliability, safety and performance.

The Audi A4/S4 outsold the Genesis G80 by almost four to one during 2022.
