Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Audi A7 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes E-Class Sedan has only front height-adjustable seat belts.

Both the A7 and E-Class Sedan 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 Sedan’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 Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. The E-Class Sedan doesn’t offer a whiplash protection system.

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 Sedan 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A7. But it costs extra on the E-Class Sedan.

An active 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 and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The E-Class Sedan doesn’t offer a night vision system.

Both the A7 and the E-Class Sedan 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, daytime running lights, available crash mitigating brakes and lane departure warning systems.
