Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi A6 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Toyota Avalon doesn’t offer pretensioners for the rear seat belts.

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

Both the A6 and Avalon have child safety locks to prevent children from opening the rear doors. The A6 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 Avalon’s 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.

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 Avalon 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.

The A6 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Avalon doesn’t offer all-wheel drive.

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 Avalon doesn’t offer a night vision system.

Both the A6 and the Avalon have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

The Audi A6 weighs 562 to 706 pounds more than the Toyota Avalon. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

The A6 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Avalon’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

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

Engine

The A6’s 3.0 turbo V6 hybrid produces 34 more horsepower (335 vs. 301) and 102 lbs.-ft. more torque (369 vs. 267) than the Avalon’s 3.5 DOHC V6.

As tested in Motor Trend the Audi A6 is faster than the Toyota Avalon V6:

Fuel Economy and Range

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

In heavy traffic or at stoplights the A6’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Avalon doesn’t offer an automatic engine start/stop system.

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

The A6 has 4.8 gallons more fuel capacity than the Avalon XLE’s standard fuel tank (19.3 vs. 14.5 gallons), for longer range between fill-ups. The A6 has 3.5 gallons more fuel capacity than the Avalon XSE/Limited/Touring’s standard fuel tank (19.3 vs. 15.8 gallons).

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 Avalon doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

For better stopping power the A6’s brake rotors are larger than those on the Avalon:

The A6’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Avalon are solid, not vented.

The A6 stops much shorter than the Avalon:

Tires and Wheels

For better traction, the A6 has larger standard tires than the Avalon (245/45R19 vs. 215/55R17). The A6’s optional tires are larger than the largest tires available on the Avalon (255/40R20 vs. 235/40R19).

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 Avalon XLE’s standard 55 series tires. The A6 Prestige’s optional tires have a lower 35 series profile than the Avalon XSE/Touring’s 40 series tires.

For better ride, handling and brake cooling the A6 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Avalon XLE. The A6 Prestige’s optional 21-inch wheels are larger than the 19-inch wheels on the Avalon XSE/Touring.

Suspension and Handling

For a smoother ride and more stable handling, the A6’s wheelbase is 2.1 inches longer than on the Avalon (115.1 inches vs. 113 inches).

For better handling and stability, the track (width between the wheels) on the A6 is 1.4 inches wider in the front and .2 inches wider in the rear than the average track on the Avalon.

The A6 Prestige handles at .93 G’s, while the Avalon Touring pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The A6 Prestige executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the Avalon Touring (24.9 seconds @ .75 average G’s vs. 26.8 seconds @ .65 average G’s).

For better maneuverability, the A6’s turning circle is 1.3 feet tighter than the Avalon XLE’s (36.4 feet vs. 37.7 feet). The A6’s turning circle is 2.3 feet tighter than the Avalon Limited/Touring’s (36.4 feet vs. 38.7 feet).

Cargo Capacity

To make loading and unloading groceries and cargo easier, especially for short adults, the A6 Prestige has a standard power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The Avalon doesn’t offer a power trunk.

Servicing Ease

The engine in the A6 is mounted longitudinally (North-South), instead of sideways, as in the Avalon. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Toyota. J.D. Power ranks Audi third in service department satisfaction. With a 44% lower rating, Toyota is ranked 17th.

Ergonomics

Unlike the driver-only memory system in the Avalon Limited/Touring, the A6 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.

The A6 Prestige has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Avalon doesn’t offer a heads-up display.

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 Avalon 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 Avalon XLE/Touring’s standard manually variable intermittent wipers have to be constantly adjusted.

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 Avalon doesn’t offer headlight washers.

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

A power rear sunshade is optional in the A6 to help block heat and glare for the rear passengers. The Avalon doesn’t offer a rear sunshade.

Recommendations

Motor Trend performed a comparison test in its January 2019 issue and they ranked the Audi A6 Prestige higher than the Toyota Avalon Touring.
