=Aluminum ASF®= “What Audi can do with aluminum these days is truly impressive.” -Insideline.com The exclusive lightweight design of ASF® technology offers a number of significant advantages over traditional steel construction. By utilizing lightweight aluminum, ASF technology helps reduce vehicle weight as well as enhance body strength and handling. The weight savings offers distinct advantages, resulting in better acceleration and braking, because less mass needs to be moved and stopped. Compared to the previous A8, Audi has increased the stiffness by 25 percent, while reducing weight by up to 20 percent. This is achieved through the use of a lattice-type structure that is pressure-cast to which extruded components are affixed. This framework provides an anchor point for the aluminum body panels. Other critical areas, such as the B-pillars, utilize high-strength steel alloys to further increase passenger safety. Passive safety is also enhanced through the use of ASF. The doors of the A8 are aluminum with the added protection of steel impact beams. Thanks to the overall design of ASF, the body is stiffer, resulting in higher torsional rigidity. This stiffness helps enhance handling by enabling the car to be more responsive, more precise and more stable. Another benefit of the extensive use of aluminum is its ability to absorb vibration, creating a smoother, quieter ride. The A8 ASF is the latest generation of this revolutionary technology. The net effect for you is better handling, fuel efficiency* and an increased power-to-weight ratio.

=Night Vision with Pedestrian Detection= Night vision assistant utilizes infrared imaging technology and detects the presence of people and some large animals up to 1,000 feet away, shown in the night vision display in one of two stages. Once detected, the pedestrian is highlighted in yellow in the color driver information display. If the detected object moves into the path of the vehicle, the system warns the driver audibly and highlights the image in red.

=Audi advanced key= With this advanced keyless entry system, your vehicle can be locked and unlocked, the steering wheel can be released and your vehicle can be started without removing the key from a pocket or purse.

=Holistic Safety Systems= Safety is integrated in every aspect of the Audi A8. From the passive safety of ASF® with high-strength, lightweight alloys in critical areas, to the latest in advanced driver assist technology, we have integrated multiple levels of safety features to mitigate the unexpected. When prevention isn’t enough, the combination of crumple zones and high-strength aluminum helps deliver a tremendous level of protection for the driver and passengers. Crumple zones, at the front and rear of the vehicle, are designed to dissipate the energy and force of a collision by deforming upon impact in a pre-programmed fashion. A full complement of ten standard airbags provide an additional measure of safety. They include front-impact airbags for the driver and passenger and are designed to help protect the head. Seat-mounted, side-impact airbags for the front seat occupants are designed to help protect the thorax in a collision. And the side-curtain airbags offer front and rear occupants head protection in the event of a side collision or rollover.

=Audi pre sense= The A8 offers the latest, most advanced safety systems designed to help protect you in the event of an accident while also helping to avoid them in the first place. At the heart of this technology is Audi pre sense. All A8 models are equipped with standard Audi pre sense. This system offers a collection of integrated systems that will initiate vehicle responses according to driver inputs and vehicle behaviors. These systems work together to add safety and security to the driver proactively warning you of approaching danger. Once danger is detected, the system takes preventative measures to reduce the severity of certain types of collisions. As a part of the optional Driver Assist package, Audi pre sense plus offers additional safety measures by utilizing Audi adaptive cruise control with Stop & Go function, Audi lane assist as well as Audi side assist. These advanced technologies work in concert to monitor traffic and alert the driver to potential danger in four phases. Warnings first come through optical and acoustic signals, and then through a series of controlled partial and full brake assists in order to reduce the severity of the impeding collision. When a collision scenario is detected from the rear, for example, seats and headrests are adjusted for maximum support. Additional protection comes from the pneumatic seat side sections that will be inflated while the airbags are pre-conditioned.

=Adaptive cruise control with Stop & Go Function= Adaptive cruise control builds on the functionalities of the cruise control system and within certain system limits, maintains the driver-selected comfort spacing from the vehicle in front automatically. The system uses video cameras along with short- and long-distance radar sensors to measure the distance to the vehicle ahead, detecting the risk of a frontal collision and issuing a number of warnings. Part of this response includes a partial application of the brakes and if need be, full braking via Audi braking guard.

=Side Assist= Active at speeds over 19 MPH, Audi side assist monitors blind spots and fast-approaching vehicles at a range of 150 ft. When a vehicle is present within the monitored area, the system warns you via LED lights in the exterior mirrors.

=ESC= The Electronic Stability Control (ESC) helps keep the vehicle traveling in its intended direction by utilizing ABS, the traction control of ASR and the electronic brake force distribution of EBD. Specifically, when ESC detects loss of traction, it automatically cuts the throttle and applies the brakes to help “steer” the vehicle where you intend to go. Braking is automatically applied to each wheel: at the outer front wheel to mitigate oversteer, or the inner rear wheel to mitigate understeer.
