The Audi RS 5 Sportback has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection.

The AMG E-Class Sedan doesn’t offer a front passenger side knee airbag.

The RS 5 Sportback 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.
