Safety Comparison

The A6’s front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GS Series doesn’t offer pre-crash pretensioners.

The A6 Premium Plus/Prestige offers an optional Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The GS Series 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.

Both the A6 and the GS Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The A6’s corrosion warranty is 6 years longer than the GS Series’ (12 vs. 6 years).

There are over 33 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the A6’s warranty.

Reliability Comparison

The battery on the A6 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the A6’s battery 20 to 30 degrees cooler, its life is increased by years. The GS Series’ battery is in the hot engine compartment.

Consumer Reports

Tires and Wheels Comparison

For better traction, the A6’s optional tires are larger than the largest tires available on the GS Series (255/40R19 vs. 235/40R19).

The A6 Prestige’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 GS Series F-Sport’s 40 series front tires.

For better ride, handling and brake cooling the A6 Prestige offers optional 20-inch wheels. The GS Series’ largest wheels are only 19-inches.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the A6’s wheelbase is 2.5 inches longer than on the GS Series (114.7 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the A6 is 2.1 inches wider in the front and 1.1 inches wider in the rear than on the GS Series.

The A6 3.0T Quattro handles at .95 G’s, while the GS 450h pulls only .89 G’s of cornering force in a Motor Trend skidpad test.

The A6 3.0T Quattro executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the GS 450h (25.1 seconds @ .74 average G’s vs. 26.9 seconds @ .68 average G’s).

Passenger Space Comparison

The A6 has .2 inches more front shoulder room, 1.1 inches more rear legroom and .6 inches more rear shoulder room than the GS Series.

Cargo Capacity Comparison

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

Ergonomics Comparison

If the windows are left down on the A6 the driver can raise them all using the key in the outside lock cylinder; on a hot day the driver can lower the windows. The driver of the GS Series can only operate the windows from inside the vehicle, with the ignition on.

The A6’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GS Series’ standard manually variable intermittent wipers have to be constantly adjusted.

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 GS Series doesn’t offer heated windshield washer nozzles.

Economic Advantages Comparison

Insurance will cost less for the A6 owner. The Complete Car Cost Guide estimates that insurance for the A6 will cost $1530 less than the GS Series over a five-year period.

According to The Car Book by Jack Gillis, the A6 is less expensive to operate than the GS Series because typical repairs cost much less on the A6 than the GS Series, including $31 less for a water pump, $276 less for an alternator, $86 less for fuel injection and $272 less for front struts.

Recommendations Comparison

Both are recommended, but Consumer Reports® chose the Audi A6 as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance.

Car and Driver performed a comparison test in its March 2012 issue and the Audi A6 3.0T Quattro won out over the Lexus GS 350.

J.D. Power and Associates rated the A6 second among midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The GS Series was rated third.

The A6 was chosen as one of Car and Driver’s “Top Ten” for 4 of the last 14 years. The GS Series has never been a Car and Driver “Top Ten” pick.

The Audi A6/S6 outsold the Lexus GS Series by 10% during the 2012 model year.
