Safety Comparison

Both the A6 and E-Class Sedan have child safety locks to prevent children from opening the rear doors. The A6 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 A6 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.

An active infrared night vision system optional on the A6 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 projects the image on the windshield, near the driver’s line of sight. The E-Class Sedan doesn’t offer a night vision system.

Both the A6 and the E-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

To allow full utilization of available cargo room, the A6’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The E-Class Sedan’s useful trunk space is reduced by its intrusive beam hinge.

Ergonomics Comparison

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

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

The A6 has standard heated front seats. Heated front seats cost extra on the E-Class Sedan. The A6 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the E-Class Sedan.

Economic Advantages Comparison

The A6 will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the A6 will retain 48% to 49% of its original price after three years, while the E-Class Sedan only retains 39% to 48%.
