Safety

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A6. But it costs extra on the LS Series.

A passive infrared night vision system optional on the A6 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The LS Series doesn’t offer a night vision system.

Both the A6 and the LS Series 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, post-collision automatic braking systems, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

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

There are over 26 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the A6’s warranty.

Engine

The A6’s standard 3.0 turbo V6 hybrid produces 369 lbs.-ft. more torque (369 vs. ) than the LS 500h’s standard 3.5 DOHC V6 hybrid.

Fuel Economy and Range

On the EPA test cycle the A6 3.0T gets better fuel mileage than the LS 500 AWD (22 city/29 hwy vs. 18 city/27 hwy).

To lower fuel costs and make buying fuel easier, the Audi A6 uses regular unleaded gasoline (premium recommended for maximum performance). The LS Series requires premium, which can cost 20 to 55 cents more per gallon.

Transmission

The A6 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 LS Series doesn’t offer an SMG or a conventional manual transmission.

Tires and Wheels

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

The A6’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the LS Series’ standard 50 series tires. The A6 Prestige’s optional tires have a lower 35 series profile than the LS Series F Sport’s 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the A6 Prestige offers optional 21-inch wheels. The LS Series’ largest wheels are only 20-inches.

Suspension and Handling

For better maneuverability, the A6’s turning circle is .4 feet tighter than the LS Series’ (36.4 feet vs. 36.8 feet). The A6’s turning circle is 3 feet tighter than the LS Series AWD’s (36.4 feet vs. 39.4 feet).

Chassis

The Audi A6 may be more efficient, handle and accelerate better because it weighs about 450 to 850 pounds less than the Lexus LS Series.

The A6 is 11.7 inches shorter than the LS Series, making the A6 easier to handle, maneuver and park in tight spaces.

Passenger Space

The A6 has .7 inches more front headroom, .3 inches more front legroom, .8 inches more rear headroom and .1 inches more rear shoulder room than the LS Series.

Cargo Capacity

The A6’s standard rear seats fold to accommodate long and bulky cargo. The LS Series doesn’t offer folding rear seats.

Recommendations

The Audi A6/S6 outsold the Lexus LS Series by 34% during the 2018 model year.
