Compare the2024 Audi A6VS 2023 Genesis G90

The Audi A6 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 G90 doesn’t offer a front passenger side knee airbag.

The A6 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 G90 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.

Both the A6 and the G90 have standard driver and passenger frontal airbags, front and rear 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.

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 vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A6 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The G90 has not been fully tested, yet.

The A6’s corrosion warranty is 5 years longer than the G90’s (12 vs. 7 years).

J.D. Power and Associates rated the A6 third among midsize premium cars in their 2023 Initial Quality Study. The G90 isn’t in the top three in its category.

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.

As tested in Motor Trend the A6 55 TFSI 3.0 turbo V6 hybrid is faster than the G90 3.5T e-SC 3.5 turbo/supercharged V6 hybrid:

On the EPA test cycle the A6 gets better mileage than the G90:

Regenerative brakes improve the A6’s fuel efficiency by converting inertia back into energy instead of wasting it. The G90 doesn’t offer a regenerative braking system.

The A6 offers an available 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 G90 doesn’t offer an SMG or a conventional manual transmission.

The A6 stops much shorter than the G90:

For better traction, the A6’s optional tires are larger than the largest tires available on the G90 (255/40R20 vs. 245/45R20).

The A6 Prestige handles at .93 G’s, while the G90 3.5T e-SC pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The A6 Prestige executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the G90 3.5T e-SC (24.9 seconds @ .75 average G’s vs. 26.2 seconds @ .68 average G’s).

The Audi A6 may be more efficient, handle and accelerate better because it weighs about 750 to 900 pounds less than the Genesis G90.

The A6 is 1 foot, 1.3 inches shorter than the G90, making the A6 easier to handle, maneuver and park in tight spaces.

The A6 has a much larger trunk than the G90 (13.7 vs. 12 cubic feet).

The A6’s standard rear seats fold to accommodate long and bulky cargo. The G90 doesn’t offer folding rear seats, only a ski pass-through.

The A6 has a 3500 lbs. towing capacity. The G90 has no towing capacity.

A Service Interval Display is standard on the A6 to save the owner time and money by calculating maintenance intervals for oil changes and vehicle inspections based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Genesis doesn’t offer a maintenance reminder on the G90.

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.

The A6’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The G90 does not have an oil pressure gauge.

If the windows are left open on the A6 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 G90 can only close the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the A6 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G90 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 A6’s headlights were rated “Good” to “Acceptable” by the IIHS, while the G90’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 A6 Premium Plus/Prestige has standard headlight washers to keep headlight output high. The G90 doesn’t offer headlight washers.

To help drivers see further while navigating curves, the A6 Prestige has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The G90 doesn’t offer cornering lights.

Insurance will cost less for the A6 owner. The Complete Car Cost Guide estimates that insurance for the A6 will cost $1800 to $4680 less than the G90 over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi A6 will be $25977 to $31614 less than for the Genesis G90.

Consumer Reports® recommends the Audi A6, based on reliability, safety and performance.

The Audi A6/S6/RS 6 outsold the Genesis G90 by over five to one during 2022.
