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

Both the A6 Allroad and Outback have child safety locks to prevent children from opening the rear doors. The A6 Allroad 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 Outback’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 Audi A6 Allroad has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Outback doesn’t offer a front passenger side knee airbag.

The A6 Allroad 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 Outback 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.

A passive infrared night vision system optional on the A6 Allroad 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 Outback doesn’t offer a night vision system.

Both the A6 Allroad and Outback offer rear cross-traffic warning, but the A6 Allroad with Rear Cross-Traffic Assist also has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Outback’s Rear Cross Traffic Alert doesn’t automatically brake.

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

The Audi A6 Allroad weighs 504 to 745 pounds more than the Subaru Outback. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

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

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

Audi pays for scheduled maintenance on the A6 Allroad for 3 years and 30,000 miles. Audi will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Subaru doesn’t pay scheduled maintenance for the Outback.

Engine

The A6 Allroad’s 3.0 turbo V6 hybrid produces 155 more horsepower (335 vs. 180) and 191 lbs.-ft. more torque (369 vs. 178) than the Outback 2.5i’s standard 2.5 DOHC 4-cylinder. The A6 Allroad’s 3.0 turbo V6 hybrid produces 75 more horsepower (335 vs. 260) and 92 lbs.-ft. more torque (369 vs. 277) than the Outback XT/Wilderness’ standard 2.4 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the A6 Allroad gets better mileage than the Outback:

			MPG
A6 Allroad
	AWD	3.0 turbo V6 Hybrid	21 city/30 hwy
Outback
	AWD	2.4 turbo flat-4	21 city/29 hwy
		Wilderness 2.4 turbo flat-4	21 city/27 hwy

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

The A6 Allroad has 1.3 gallons more fuel capacity than the Outback (19.3 vs. 18 gallons), for longer range between fill-ups.

Transmission

The A6 Allroad’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 Outback doesn’t offer launch control.

Brakes and Stopping

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

	A6 Allroad	Outback
Front Rotors	14.7 inches	12.4 inches
Rear Rotors	13 inches	11.8 inches

Tires and Wheels

For better traction, the A6 Allroad has larger tires than the Outback (245/45R20 vs. 225/65R17).

The A6 Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Outback Wilderness’ standard 65 series tires. The A6 Allroad’s tires are lower profile than the Outback XT’s 55 series tires.

For better ride, handling and brake cooling the A6 Allroad has standard 20-inch wheels. Smaller 17-inch wheels are standard on the Outback Wilderness. The Outback’s largest wheels are only 19-inches.

Suspension and Handling

The front and rear suspension of the A6 Allroad uses air springs for a smoother, controlled ride than the Outback, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The A6 Allroad has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The A6 Allroad’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Outback doesn’t offer a load leveling suspension.

The A6 Allroad has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Outback doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the A6 Allroad’s wheelbase is 7.1 inches longer than on the Outback (115.2 inches vs. 108.1 inches).

For better handling and stability, the track (width between the wheels) on the A6 Allroad is 2.6 inches wider in the front and .2 inches wider in the rear than the average track on the Outback.

Chassis

The A6 Allroad is 8.6 inches shorter in height than the Outback, making the A6 Allroad much easier to wash and garage and drive (lower center of gravity).

Cargo Capacity

A low lift-over trunk design makes loading and unloading the A6 Allroad easier. The A6 Allroad’s trunk lift-over height is 25 inches, while the Outback’s liftover is 28.3 inches.

The A6 Allroad’s cargo area is larger than the Outback’s in almost every dimension:

	A6 Allroad	Outback
Length to seat (2nd/1st)	46.3”/77.9”	42.8”/75.9”
Min Width	41.3”	43.3”

To make loading groceries and cargo easier when your hands are full, the A6 Allroad’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Outback doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

The A6 Allroad uses gas struts to support the hood for easier service access. The Outback uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the Outback (except Premium), the A6 Allroad Prestige has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and climate settings and the front passenger seat also adjusts to the new passenger’s preset preferences.

The A6 Allroad’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The Outback doesn’t offer an easy entry system.

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

The power windows standard on both the A6 Allroad and the Outback have locks to prevent small children from operating them. When the lock on the A6 Allroad is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Outback prevents the driver from operating the rear windows just as it does the other passengers.

If the windows are left open on the A6 Allroad the driver can close all of them 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 Outback can only operate the windows from inside the vehicle, with the ignition on.

The A6 Allroad’s standard Audi Advanced Key allows you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Keyless Access and Start standard on the Outback doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The A6 Allroad’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 Outback’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the A6 Allroad to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Outback doesn’t offer heated windshield washer nozzles.

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 Allroad has standard headlight washers to keep headlight output high. The Outback doesn’t offer headlight washers.

The Audi A6 Allroad has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors costs extra on the Outback and aren't offered on the Premium/Limited.

The A6 Allroad has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the Outback.

The A6 Allroad Prestige has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Outback.

The A6 Allroad has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Outback Premium/Limited/Wilderness/Touring/Onyx.

The Audi A6 Allroad has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Subaru charges extra for Homelink® on the Outback.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi A6 Allroad has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Outback.

The A6 Allroad Prestige’s Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Park Assist Plus will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Outback doesn’t offer an automated parking system.
