The Audi A5 Sportback’s engine uses a cast iron block for durability, while the Legacy’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The battery on the A5 Sportback is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the A5 Sportback’s battery 20 to 30 degrees cooler, its life is increased by years. The Legacy’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Audi vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Audi 22nd in initial quality. With 7 more problems per 100 vehicles, Subaru is ranked 25th.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Subaru vehicles. J.D. Power ranks Audi 8th in reliability, above the industry average. With 12 more problems per 100 vehicles, Subaru is ranked 14th.

The Legacy’s suspension doesn’t offer adjustable shock absorbers.

The A5 Sportback 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 Legacy doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the A5 Sportback’s wheelbase is 2.9 inches longer than on the Legacy (111.2 inches vs. 108.3 inches).

The A5 Sportback 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 Legacy doesn’t offer a heads-up display.

The power windows standard on both the A5 Sportback and the Legacy have locks to prevent small children from operating them. When the lock on the A5 Sportback is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Legacy prevents the driver from operating the other windows just as it does the other passengers.

The A5 Sportback’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Legacy’s standard rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the A5 Sportback the driver can close them all at the outside door handle. On a hot day the driver can also lower the windows the same way. The driver of the Legacy can only operate the windows from inside the vehicle, with the ignition on.

The A5 Sportback’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 Legacy’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the A5 Sportback to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Legacy 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 A5 Sportback Prestige has standard headlight washers to keep headlight output high. The Legacy doesn’t offer headlight washers.

The A5 Sportback’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the Legacy Premium/Sport/Limited/Touring.

The A5 Sportback 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 Legacy Premium/Sport/Limited/Touring.

Both the A5 Sportback and the Legacy offer rear vents. For greater rear passenger comfort, the A5 Sportback has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Legacy doesn’t offer rear air conditioning vents, only heat vents.

The A5 Sportback Prestige’s Park Steering Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Legacy doesn’t offer an automated parking system.
