Both the A7 and E-Class Wagon 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 E-Class Wagon’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 A7 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 E-Class Wagon 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 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 E-Class Wagon doesn’t offer a night vision system.

Both the A7 and the E-Class Wagon 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, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the A7 the rating of “Top Pick” for 2019, a rating granted to only 106 vehicles tested by the IIHS. The E-Class Wagon has not been tested, yet.

J.D. Power and Associates rated the A7 third among midsize premium cars in their 2019 Initial Quality Study. The E-Class Wagon isn’t in the top three in its category.

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 Mercedes vehicles. J.D. Power ranks Audi 8th in reliability, above the industry average. With 10 more problems per 100 vehicles, Mercedes is ranked 13th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Audi 10 places higher in reliability than Mercedes.

On the EPA test cycle the A7 SMG gets better fuel mileage than the E-Class Wagon (22 city/29 hwy vs. 19 city/26 hwy).

On the EPA test cycle the A7 Auto gets better fuel mileage than the E 450 4MATIC Wagon (22 city/29 hwy vs. 19 city/26 hwy).

Regenerative brakes improve the A7’s fuel efficiency by converting inertia back into energy instead of wasting it. The E-Class Wagon doesn’t offer a regenerative braking system.

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 E-Class Wagon doesn’t offer a cap-less fueling system.

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 E-Class Wagon 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 E-Class Wagon doesn’t offer launch control.

For better traction, the A7’s optional tires are larger than the largest tires available on the E-Class Wagon (255/40R20 vs. 245/45R18).

The A7 Prestige’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the E-Class Wagon’s optional 40 series tires.

For better ride, handling and brake cooling the A7 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the E-Class Wagon. The A7 Prestige’s optional 21-inch wheels are larger than the 19-inch wheels optional on the E-Class Wagon.

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 E-Class Wagon; 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.

For better handling and stability, the track (width between the wheels) on the A7 is 2.3 inches wider in the front and 1 inch wider in the rear than on the E-Class Wagon.

The A7 Prestige handles at .93 G’s, while the E 450 4MATIC Wagon pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the A7’s turning circle is 2.6 feet tighter than the E-Class Wagon’s (36.4 feet vs. 39 feet).

For enhanced passenger comfort on long trips the A7’s rear seats recline. The E-Class Wagon’s middle row seats don’t recline.

The A7’s power parking brake sets with one touch and releases with one touch or automatically. The E-Class Wagon’s parking brake has to released manually.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A7 Premium Plus/Prestige has standard headlight washers to keep headlight output high. The E-Class Wagon doesn’t offer headlight washers.

A power rear sunshade is optional in the A7 to help block heat and glare for the rear passengers. The E-Class Wagon doesn’t offer a rear sunshade.

The A7 has standard heated front seats. Heated front seats cost extra on the E-Class Wagon. The A7 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the E-Class Wagon.
