The rear seatbelts optional on the E-Class Sedan inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The A7 doesn’t offer inflatable seatbelts.

The E-Class Sedan’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The A7 doesn’t offer a whiplash protection system.

The E-Class Sedan’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The A7 doesn’t offer a driver alert monitor.

Both the E-Class Sedan and the A7 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, around view monitors and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the E-Class Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The A7 is only a standard “Top Pick” for 2019.

The E-Class Sedan has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing.

The E-Class Sedan has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A7 doesn’t offer a remote starting system.

Unlike the driver-only memory system in the A7, the E-Class Sedan has standard driver and 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 E-Class Sedan’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The A7’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer fluid is standard on the E-Class Sedan to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The A7 doesn’t offer heated windshield washer fluid.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The E-Class Sedan’s headlights were rated “Good” to “Acceptable” by the IIHS, while the A7’s headlights are rated “Acceptable” to “Poor.”

The E-Class Sedan offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The A7 doesn’t offer a house-current electrical outlet.

The E-Class Sedan’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The A7 doesn’t offer an automated parking system.
