to a trendsetting design, state-of-the-art suspension solutions, touchscreen operating concept and superla- tive comfort, the luxury saloon demonstrates Vorsprung durch Technik right across the board Below you will find summarised the key features of the Audi A8 Engines 3.0l V6 TDI engine with mono turbocharger >> Max power: 210 kW (286 hp) >> Max torque: 600 Nm 3.0l V6 TFSI engine with mono turbocharger >> Max power: 250 kW (340 hp) >> Max torque: 500 Nm The Audi A8 (type 4N) is the first Audi to come as standard with an electrified driveline For this purpose, the engines are equipped with a mildhybrid system Displays and operation A new operating and display concept incorporating MMI touch response technology with touchscreens, a switch panel (optional) and an illuminated button module with tactile and audible freeback, intelligent handwriting entry with whole-word and multifinger recognition An Audi virtual cockpit with full HD resolution and optional head-up display Driver assistance systems For the first time, a central driver assistance control unit (zFAS) utilises the data generated by the sensors to comprehensively map the area around the vehicle This map is updated continuously and used by a number of assistance functions For example, adaptive cruise assist is a new driver assistance system, which is offered for the first time in the Audi A8 (type 4N) as optional equipment It combines three formerly independent systems - adaptive cruise control, Audi active lane assist with "early" corrective steering point and traffic jam assist - in a single driver assist system Intersection assist helps the driver in situations in which cross traffic ahead of the vehicle can only be seen late due to impaired visibility Suspension The front and rear axles have a precision five-link construction (dynamic allwheel-drive steering is optional) A sport differential is available as an option for even more dynamic handling The adaptive air suspension has hydraulically controlled dampers which are adjustable to 4 height levels A fully active Audi A1 active suspension is optional It controls each wheel separately and allows a wide spread between comfort and sportiness < Back Forward > Ξ Contents Air conditioning Body A further, new refrigerant is used in the Audi A8 (type 4N): carbon dioxide It has the chemical formula CO2 and is also known as R744 It contains neither fluorine nor chlorine and is produced in a series of natural processes without depleting the earth's ozone layer The body of the Audi A8 (type 4N) follows the Audi Space Frame (ASF) principle It is assembled from aluminium parts – the classic composite of cast nodal joints, extruded profiles and sheet metal The occupant cell is made from hot-formed steel components, complemented by an ultra-highstrength, torsionally rigid rear bulkhead made from carbon-fibre composite (CFC) A magnesium dome strut completes the lightweight construction concept 662_068 Power transmission Electrical system 8-speed automatic gearbox 0D5 has been redesigned and improved for the Audi A8 The use of an auxiliary hydraulic pump allows the internal combustion to be shut off under coasting in certain situations This saves fuel The rear final drive 0G2 is used on the rear axle The "quattro with sport differential" drive system with sport differential 0D3 is optional The MHEV technology of Audi is based on the newly developed 48 volt electrical system – it supplies the 12 volt electrical system, which in this case is the electrical subsystem The 48-volt electrical system is powered by a belt alternator starter (BAS) which is connected to the engine belt drive A lithium-ion battery, which is positioned safely under the luggage compartment floor, serves as an energy storage device < Back Forward > Ξ Contents 1488 (1473) Dimensions 1049 1644 1633 1945 2130 662_074 697 105 1) 995 662_073 989 3128 1185 5302 662_075 697 983 104 1) Illustration shows Audi A8 L 989

Forward > Ξ Contents Body Introduction The new Audi A8 (type 4N) is based on an advanced ASF body structure which, for the first time, is composed of different materials With a mix of aluminium, steel, magnesium and carbon fibre reinforced polymer (CFRP), the load-bearing structure combines four different lightweight materials However, the largest proportion (58%) is represented by aluminium components which, as cast nodal plates, extruded sections and sheet metal panels, are the characterisic elements of an ASF construction system A rear bulkhead made of carbon fibre saves around 50% compared with its predecessor and helps to make the body rigid and strong in spite of the lightweight design The intelligent material mix is completed by a dome strut which is 28% lighter and made of magnesium A comparison with the topic of torsional rigidity shows that the value has been improved by up to 24% compared with the predecessor Key: Sheet aluminium Die-cast aluminium Aluminium section Ultra-high-strength steel (hot-stamped) Carbon fibre reinforced polymer (CFRP) Magnesium Advanced high-strength steel High-strength steel Soft steel Note The depicted image shows an Audi A8 with a standard wheelbase The body of the long-wheelbase version (A8 L) is 130 mm longer in the vicinity of the B post and heel board < Back Forward > Ξ Contents Connection system The following connection

Seaming (total seam length: approx 15243 mm) Bonding (total seam length: approx 112014 mm) 662_192 < Back Forward > Ξ Contents Safety cell The occupant cell, also called the safety cell, is made of aluminium and conventional hot-formed steel The occupant cell comprises the lower area of the end wall, the side sills, the B posts and the front area of the roof arch Some of these sheet metal blanks are produced with different thicknesses using tailored technologies and are also partially tempered if necessary This reduces the weight and increases the strength especially in extremely safetycritical areas 662_193 B post The B posts are adapted specially to the areas of body rigidity and crash requirements, and are produced using tailor rolled blank technology These are flexibly rolled blanks, where variations in sheet-metal thickness are produced by controlled opening and closing of the gap between the rollers These variations in sheetmetal thickness not only save weight, but also create defined crumple zones which provide protection in the event side-on impact The sheet metal thicknesses vary between 1.5 mm and 2.0 mm Partial tempering: The individual zones of the B post are cooled in the mould at different rates during hot working, giving them different strength characteristics In a side-on impact the bottom section of the B post deforms in order to absorb energy On the other hand, less deformation takes place in the upper section of the B post (at head height) Ultra-high-strength High-strength 662_194 10 662_195 < Back Forward > Ξ Contents Pre sense turn-off assist Audi pre sense turn-off assist can help the driver with turn-off manoeuvres In models equipped with Audi pre sense turn-off assist, the following actions can be taken: >> Reconfiguration of hydraulic brake assist >> Automatic emergency braking1) >> Display of corrective action by Audi pre sense in the instrument cluster (visual and audible) Installation location To implement Audi pre sense turn-off assist, the vehicle requires: >> Adaptive cruise assist with the ADR sensor, right G259 and the ACC control unit J428 >> Front camera for driver assistance systems R242 >> The control unit for laser distance control J1122 Front camera for driver assistance systems R242 Adaptive cruise assist with ADR sensor, right G259 and ACC control unit J428 Control unit for laser distance control J1122 662_166 Function Turn-off assist is explained using a left turn-off situation in righthand traffic In driving situations involving left-hand traffic, the function helps to driver to turn off to the right The radar sensor of adaptive cruise assist, the front camera for driver assistance systems and the laser scanner of the laser distance control function continuously monitor the traffic in front of one's own vehicle The front camera for driver assistance systems and the laser scanner of the laser distance control function send the data they have acquired to the ACC control unit J428 The ACC control unit merges the data and can instruct other systems to initiate actions appropriate to the situation The merging of data from various sources provides a very exact map of the vehicle periphery Switching turn-off assist off and on When Audi pre sense is off, turn-off assist is also off In addition, turn-off assist can be switched off separately in the MMI menu If turn-off assist is switched off separately, it stays off until the 1) function is reactivated in the MMI Turning the ignition off and on does not activate turn-off assist if it has been switched off separately Not available in all countries Reference For further information about turning Audi pre sense on and off, refer to "Audi pre sense settings", page 76 ff 94 < Back Forward > Ξ Contents Turning off to the left The driver wants to turn off to the left with his vehicle (1) Turn-off assist can only assist the driver with turning off to the left if the vehicle (1) is travelling at a speed of less than 10 kph As described under "Function", the radar sensor, the front camera and the laser scanner continuously monitor the traffic in front of one's own vehicle (1) When the turn signal is switched to the left position, the oncoming traffic is also monitored When the turn signal is switched to the left position, the ACC control unit knows that the driver intends to turn off to the left If the ACC control unit J1122 detects that turning off now would result in a critical situation involving oncoming traffic (2), it instructs the ABS control unit J104 to reconfigure hydaulic brake assist If the driver (1) were now to continue with the turn-off manoeuvre and start to drive away, this will be detected by the ACC control unit through the wheel speed sensors of the ABS control unit J104 In this case, the ACC control unit instructs the ABS control unit J104 to initiate an automatic emergency braking manoeuvre The vehicle (1) comes to a standstill in its own lane due to the emergency braking manoeuvre Visual and audible messages indicating that Audi pre sense is active appear in the instrument cluster Process diagram showing the working principle of Audi pre sense turn-off assist 662_167 Key: Reconfiguration of hydraulic brake assist Automatic braking up to emergency braking intensity Visual advance warning and/or indication of corrective action Audible

activated before turning off >> In right-hand-drive vehicles the system is only active when turning off to the left >> In left-hand-drive vehicles the system is only active when turning off to the right >> If turn-off assist is active, this is indicated both visually and audibly 95 < Back Forward > Ξ Contents Pre sense evasion assist Audi pre sense evasion assist can aid the driver with an evasion manoeuvre while approaching another vehicle In models equipped with Audi pre sense evasion assist, the following actions can be taken: >> Steering torque (corrective steering inputs) >> Braking of individual wheels >> Display of corrective action by Audi pre sense in the instrument cluster (visual and audible) Installation location To implement Audi pre sense evasion assist, the vehicle requires: >> Adaptive cruise assist with the ADR sensor, right G259 and the ACC control unit J428 >> Front camera for driver assistance systems R242 >> The control unit for laser distance control J1122 Front camera for driver assistance systems R242 Adaptive cruise assist with ADR sensor, right G259 and ACC control unit J428 Control unit for laser distance control J1122 662_166 Function Evasion assist is explained using an example in which one's own vehicle wants to pass by a vehicle on the left Evasion assist behaves analogously when passing by a vehicle on the right The radar sensor of adaptive cruise assist, the front camera for driver assistance systems and the laser scanner of the laser distance control function continuously monitor the traffic in front of one's own vehicle The front camera for driver assistance systems and the laser scanner of the laser distance control function send the data they have acquired to the ACC control unit J428 The ACC control unit merges the data and can instruct other systems to initiate actions appropriate to the situation The merging of data from various sources provides a very exact map of the vehicle periphery Switching evasion assist off and on When Audi pre sense is off, evasion assist is also off In addition, evasion assist can be switched off separately in the MMI menu If evasion assist is switched off separately, it stays off until the function is reactivated in the MMI Turning the ignition off and on does not activate evasion assist if it has been switched off separately Reference For further information about turning Audi pre sense on and off, refer to "Audi pre sense settings", page 76 ff 96 < Back Forward > Ξ Contents Evasion maneouvre The vehicle (1) wants to evade the vehicle (2) travelling ahead As described under "Function", the radar sensor, the front camera and the laser scanner continuously monitor the traffic in front of one's own vehicle (1) Before evasion assist can provide the driver with assistance, Audi pre sense front has already identified a critical situation and initiated the following actions: >> Visual prewarning >> Audible prewarning >> Prefilling of the brake system >> Adaptation of hydraulic brake assist >> Acute warning by braking impulse Evasion assist computes a suitable evasion line based on various items of information, such as one's own speed and the lane in which the vehicle ahead in driving If vehicle (1) deviates too far from the evasion line within certain bounds, evasion assist will, after the acute warning is issued, try to guide the vehicle (1) along the evasion line by providing steering assistance along the evasion line of the vehicle (2) The vehicle (1) is additionally stabilised by braking individual wheels Evasion assist can only help the driver (1) when the driver (1) carries out the evasion process actively by making corrective steering inputs himself Visual and audible messages indicating that Audi pre sense is active appear in the instrument cluster If the last possible evasion point has been surpassed, no assistance is provided by evasion assist Process diagram showing the working principle of Audi pre sense evasion assist 662_165 Key: Assistive steering torque Braking of individual wheels Visual advance warning and/or indication of corrective action Audible warning beep System characteristics of the evasion assist function >> Evasion assist is active after the acute warning (brake warning) is issued >> Evasion assist is not active if the last possible evasion point has been surpassed >> Evasion assist does not provide assistance unless the driver is actively steering the vehicle >> Evasion assist is available at speeds of between about 30 to 150 kph >> and helps the driver to steer around an obstacle on the left or right 97 < Back Forward > Ξ Contents Driver assistance systems Adaptive cruise assist Introduction Adaptive cruise assist is a new driver assist system which is offered for the first time in the Audi A8 (type 4N) as optional equipment It combines formerly independent systems - adaptive cruise control, Audi active lane assist with "early" corrective steering point and traffic jam assist - in a single driver assist system System configuration in the Audi Q7 (type 4M) and Audi A4/A5 (type 8W) Adaptive cruise control (ACC) Audi active lane assist "early" corrective steering point Traffic jam assist Adaptive cruise assist System configuration in the Audi A8 (type 4N) 662_168 With adaptive cruise assist, a combined longitudinal and lateral control assistance function is available for the first time at speeds ranging from to 250 kph "Longitudinal control" involves accelerating and braking the vehicle, while "lateral control" involves steering the vehicle However, the driver must keep his hands on the steering wheel With adaptive cruise assist, both longitudinal and lateral control functions are available to the driver However, the driver can also deactivate the lateral control function so that only the longitudinal control function stays active The vehicle behaves in much the same way as previously when driving with ACC The longitudinal control function in the Audi A8 (type 4N) is largely identical to the 4th generation ACC system used in the Audi Q7 (type 4M) and in the Audi A4/A5 (type 8W) With adaptive cruise assist, it is not possible to deactivate the longitudinal control function while the lateral control function is active With the introduction of adaptive cruise assist, active lateral control of the vehicle is available at all speeds up to 250 kph In the Audi Q7 (type 4M) or the Audi A4/A5 (type 8W), lateral control is the task of Audi active lane assist at 65 kph or higher At speeds of less than 60 kph, it is the task of traffic jam assist if a traffic jam situation has been detected by the system Lateral control may be interrupted for several seconds at the transition from active lateral control by Audi active lane assist to active lateral control by traffic jam assist, and vice versa This interruption does not apply to adaptive cruise assist, where lateral control is provided continuously As adaptive cruise assist is a driver assistance system, the driver is still fully responsible for operating the vehicle The driver's hands must stay on the steering wheel The system assists the driver, but does not relieve the driver of responsibility Adaptive Drive Assist reduces the driver's workload and makes for more comfortable driving Reference For further information about adaptive cruise assist, refer to Self Study Programme 668 "Audi A8 (type 4N) Driver assistance systems." 98 < Back Forward > Ξ Contents Intersection assist Functional description Complex traffic situation at an intersection Intersection assist is a new driver assist system, which is offered for the first time in the Audi A8 (type 4N) It helps the driver to avoid collisions with cross traffic ahead of the vehicle 662_169 Passing an narrow driveway exit with impaired visibility Intersection assist helps the driver in situations in which cross traffic ahead of the vehicle can only be seen late due to impaired visibility Impaired visibility situations such as this can occur at street intersections or when passing narrow entrances and exits 662_170 Complex situation when passing a main road In heavy traffic Intersection assist also aids the driver in complex traffic situations in which, for instance, a road user crossing ahead of the vehicle is overlooked because the driver is concentrating on other traffic 662_171 Intersection assist only responds to cross traffic if the vehicle is travelling at a speed of at least 10 kph Cross traffic can be a normal vehicle, a bus or a truck, but also a cyclist or motorcyclist If the cyclist or motorcyclist is recognised by the system, the system responds in exactly the same way as to a vehicle Intersection assist sensors To implement intersection assist, the vehicle requires two additional radar sensors, which are located behind the front bumper These radar sensors are identical in design to the rear radar sensors of the Audi A8 and are installed for the first time at this position in the Audi Both radar sensors monitor the area to the front left and right of the vehicle Due to the positioning of the two radar sensors at the extreme front left and front right of the vehicle, the system can, in certain situations, detect cross traffic even before the driver sees it Intersection assist utilises this lead time to provide the driver with feedback on critical cross traffic as early as possible so that the driver can respond to this situation Reference For further information about intersection assist, refer to Self Study Programme 668 "Audi A8 (type 4N) Driver assistance systems." 99 < Back Forward > Ξ Contents Driver assistance systems control unit J1121 Introduction The driver assistance systems control unit J1121 is a new control unit, which is used for the first time in the Audi A8 (type 4N) The control unit will be available in a total of different versions at the launch of the Audi A8 The versions have the following designations: >> Version A0 (basic version) >> Version A >> Version B >> Version C (version with widest range of functions) in the vehicle, version A0 is sufficient If, for example, the optional surround view cameras are ordered, this requires the installation of version C The optional surround view cameras are currently the only option which necessitates the installation of version C Version C will in future also be required by other park assistance systems in the Audi A8 (type 4N), but these systems will not be introduced until a later date Which versions are required in a specific Audi A8 (type 4N) depends on which driver assistance systems are ordered If only the standard driver assistance systems are installed Th individual versions are based on each other The higher the version number, the more hardware and software are integrated in the control unit However, an external analysis of the control unit shows that it is only possible to differentiate visually between 2 different versions Control unit of versions A0 and A Control unit of versions B and C 662_172 662_173 The driver assistance systems control unit J1121 is the master control unit for the following driver assistance systems: >> >> >> >> >> Basic version of main beam assist Matrix LED main beam assist Intersection assist Surround view cameras Parking system plus (in version C only, otherwise electrical system control unit J519) >> Active lane departure warning >> Emergency assist >> Camera-based traffic sign recognition Reference For further information about the driver assistance systems control unit J1121, refer to Self Study Programme 668 "Audi A8 (type 4N) Driver assistance systems." 100 < Back Forward > Ξ Contents Control unit for laser distance control J1122 Installation location A laser scanner is used in the Audi A8 (type 4N) to implement complex driver assistance functions It is installed in the centre of the bumper under the number plate carrier Function The general functional principle is similar to that of a radar sensor: instead of radar waves, the laser scanner emits laser beams which are reflected when they impinge on the surfaces of other objects It is possible to measure the distance to an object by determining the elapsed time from emittance to reception of the reflected radiation components The type of object is also determined The reflection received by the scanner is made up of a multiplicity of dots known as dot clouds The contours of the object are more well-defined than those acquired with radar technology, making it easier to classify objects Laser unit with control unit for laser distance control J1122 662_188 The horizontal detection zone covers an angular range of about 145° The range is approx 80 m on average, and object recognition is possible from a distance of 10 cm The laser scanner is, therefore, the ideal complement to the long-range radar Although the radar system has a much longer range (250 m), the coverage angle of approx 35° is much less than that of the laser scanner 662_189 Object contours are recognisable in detail Calibration The installation position of the laser scanner can be adjusted by service personnel as it is subject to tolerances Provision has been made for vertical adjustment only The adjustment is similar to that of the ACC and is carried out using a new optical target (calibration board) 662_190 Laser scanner calibration board VAS 6430/12 ACC unit To accommodate the laser scanner, an ACC unit is used on the right-hand side of the Audi A8 (type 4N) The laser scanner assumes the function of the second ACC unit ACC is no longer available as a separate option in the Audi A8 (type 4N), but rather is an optional feature of "Adaptive Cruise Assist" (ACA) in the Tour assistance package The 4th generation ACC system is identical in design and basic functions to the ACC of the Audi Q7 (type 4M) 662_191 4th generation ACC unit 101 < Back Forward > Ξ Contents
