Safety

Both the A7 and LS Series have child safety locks to prevent children from opening the rear doors. The A7 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The LS Series’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A7. But it costs extra on the LS Series.

A passive infrared night vision system optional on the A7 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 A7 and the LS Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, post-collision automatic braking systems, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The A7’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 A7’s warranty.

Fuel Economy and Range

On the EPA test cycle the A7 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 A7 uses regular unleaded gasoline (premium recommended for maximum performance). The LS Series requires premium, which can cost 20 to 55 cents more per gallon.

The A7 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The LS Series doesn’t offer a cap-less fueling system.

Transmission

The A7 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.

The A7’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The LS Series doesn’t offer launch control.

Brakes and Stopping

The A7 stops shorter than the LS Series:

Tires and Wheels

For better traction, the A7’s optional tires are larger than the largest tires available on the LS Series (255/40R20 vs. 245/45R20).

The A7’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 A7 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 A7 Prestige offers optional 21-inch wheels. The LS Series’ largest wheels are only 20-inches.

The A7 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the LS Series; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

The A7 Prestige handles at .86 G’s, while the LS 500h AWD pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The A7 Prestige executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the LS 500h AWD (26 seconds @ .69 average G’s vs. 27 seconds @ .65 average G’s).

For better maneuverability, the A7’s turning circle is .4 feet tighter than the LS Series’ (36.4 feet vs. 36.8 feet). The A7’s turning circle is 3 feet tighter than the LS Series AWD’s (36.4 feet vs. 39.4 feet).

Chassis

The Audi A7 may be more efficient, handle and accelerate better because it weighs about 400 to 650 pounds less than the Lexus LS Series.

The A7 is 10.5 inches shorter than the LS Series, making the A7 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The A7 has a much larger trunk than the LS 500 (24.9 vs. 17 cubic feet). The A7 has a much larger trunk than the LS 500h (24.9 vs. 15.2 cubic feet).

The A7’s standard rear seats fold to accommodate long and bulky cargo. The LS Series doesn’t offer folding rear seats.

Towing

The A7 has a 3500 lbs. towing capacity. The LS Series has no towing capacity.

Recommendations

Motor Trend performed a comparison test in its January 2019 issue and they ranked the Audi A7 Prestige higher than the Lexus LS Series 500 F Sport.

The Audi A7/S7/RS 7 outsold the Lexus LS Series by 17% during 2017.
