Safety

The GS Series’ lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The A6 doesn’t offer a lane departure warning system.

Both the GS Series and the A6 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, night vision systems and rear parking sensors.

Warranty

Lexus’ powertrain warranty covers the GS Series 2 years and 20,000 miles longer than Audi covers the A6. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A6 ends after only 4 years or 50,000 miles.

Reliability

J.D. Power and Associates rated the GS Series third among midsize premium cars in their 2018 Initial Quality Study. The A6 isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Lexus 8th in initial quality, above the industry average. With 21 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Audi vehicles. J.D. Power ranks Lexus first in reliability, above the industry average. With 42 more problems per 100 vehicles, Audi is ranked 13th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Lexus vehicles are more reliable than Audi vehicles. Consumer Reports ranks Lexus first in reliability. Audi is ranked 7th.

Transmission

An eight-speed automatic is standard on the Lexus GS Series, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A6.

Brakes and Stopping

For better stopping power the GS Series F Sport’s front brake rotors are larger than those on the A6:

Suspension and Handling

For better maneuverability, the GS Series’ turning circle is 1.6 feet tighter than the A6’s (34.8 feet vs. 36.4 feet). The GS Series AWD’s turning circle is 1 foot tighter than the A6’s (35.4 feet vs. 36.4 feet).

Chassis

The Lexus GS Series may be more efficient, handle and accelerate better because it weighs about 400 to 550 pounds less than the Audi A6.

The design of the Lexus GS Series amounts to more than styling. The GS Series has an aerodynamic coefficient of drag of .27 Cd. That is lower than the A6 (.29) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GS Series get better fuel mileage.

Ergonomics

The GS Series has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A6 doesn’t offer a remote starting system.

Unlike the driver-only memory system in the A6, the GS Series offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

Model Availability

The GS Series is available in both rear-wheel drive and all-wheel drive configurations. The A6 doesn’t offer a two-wheel drive configuration.

Recommendations

Consumer Reports® recommends the Lexus GS Series, based on reliability, safety and performance.
