The new Audi A8 presents the future of the luxury class. In its fourth generation, the brand’s flagship model again provides the benchmark for Vorsprung durch Technik – with a new design language, an innovative touchscreen operating concept and a systematically electrified drive. The Audi A8 is also the first production automobile in the world to have been developed for highly automated driving. From 2018, Audi will gradually be taking piloted driving functions such as parking pilot, garage pilot and traffic jam pilot into production.
Audi style: the exterior design
Sports appeal, lightweight construction and quattro – the design of the new A8 perfectly conveys Audi’s fundamental values. It embodies sporting elegance, sophistication and progressive status. The new flagship model takes the brand into a new design era.
The hexagonal Singleframe grille dominates the sedan’s upright front end. With its low position and width, it determines all adjoining lines and surfaces. The headlight shapes merge perfectly with the Singleframe. With the optional HD Matrix LED headlights, the daytime running lights are a visual extension of the grille’s top lamella. The segmented light signature divides the headlights horizontally, creating an elegant overall impression. Substantial chrome frames surround the air inlets, with a flat center inlet connecting them.
The side view with the coupé-like silhouette highlights the sporty character of the new A8. Its proportions accentuate both the front and rear wheels – prominent muscular shapes above the wheels are pointers to the brand’s quattro DNA. The low shoulder line starts right up at the headlights and runs across the door handles as far back as the rear lights. A fold below the window capping also emphasizes length. The sill rises to the rear in typical Audi style and lends the new A8 a dynamism worthy of a luxury-class car.
The rear end is inclined slightly in the direction of travel, appearing to push the sedan along even when stationary. The defining element of a lighting strip extends across the entire width. It radiates high intrinsic value thanks to the embedded chrome strip. The segmented OLEDs adjoin at its ends and combine to form a signature. Another chrome strip in the lower part of the bumper integrates the trapezoidal trims of the exhaust system.
There is a choice of twelve colors for the A8, including the new Audi colors Terra Gray, Vesuvius Gray and Seville Red. The colors Impala Beige and Navarra Blue are available for the A8 for the first time. Via the Audi exclusive program, customers can also have the luxury sedan supplied in a color of their personal choice. For those who want their car to create an even more striking visual impact, there is the option of a chrome exterior package.
HD Matrix LED, laser, OLED: the lighting
Audi leads the way in lighting technology and design. In the new A8, the technologies interact intelligently with the surroundings. For example, Audi laser lighting is used here for the first time with HD Matrix LED high beams. The laser spot is identified by an X-shape shutter and is also accentuated by blue ambient lighting. The daytime running lights with the vertical segments emphasize the technical elegance of the headlights. The laser spot is activated from a speed of 70 km/h (43.5 mph) and doubles the range of the high beam.
Each HD Matrix LED high-beam unit consists of 32 small, individually controlled light-emitting diodes that project the light in two lines. This new configuration ensures that the A8 provides even more dynamic and precise illumination together with the variable-control low-beam headlights. The light cone blanks out exclusively other road users, so as not to dazzle them. The high-precision control for the HD Matrix LED high beam is based on data supplied by the front camera.
Cornering light is produced by displacing the light’s focal point. It uses the navigation data to shine into a bend just before the steering is turned. The junction light equally comes on predictively just before a junction is reached. The segmented turning light also comes on dynamically in three stages up to a maximum angle of 90°. With all its functions complete with dynamic turn signals, each HD Matrix LED headlight incorporates 138 LEDs and one high-performance laser diode. The innovative automatic lighting prevents incorrect operation and is controlled from a new light switch module with proximity sensors and touchscreen surface.
Together with the high-end headlights, Audi supplies OLED rear lights that emit extremely smooth light. There are four ultra-flat OLEDs floating in each module, sub-divided into four individually controlled segments. Two on each side form the angular tail lights, and the other two act as the brake lights.
Below the OLEDs there is also an LED light strip that adapts to ambient brightness when the brakes are applied. The same goes for the dynamic turn signal lights positioned directly below them. There are 135 light-emitting diodes in operation in each rear light.
The lights give the new A8 exceptional presence at the very first glance. This is substantially down to the animated dynamic lighting functions. They present the luxury sedan in a unique manner when it is unlocked with the remote control key. First a point of light in the headlights runs from the outside inwards, then the blue LED on the laser spot lights up, and finally the side lights come on from the inside outwards.
Two loops with the same dynamic aesthetics run in parallel in the OLED rear lights: The light runs in a circle, initially dimmed and then at full brightness. The light presentation continues inside when the door is opened. This is accompanied by a short audio jingle. When the driver locks and leaves the new A8, the light presentation in the headlights and rear lights runs in the opposite sequence.
Spatial experience: the interior design
A new dialog between technology and aesthetics – the interior of the Audi A8 presents a comprehensive spatial experience. The architecture blends seamlessly with the new operating concept, which has virtually eliminated buttons and controls. The clean, expansive surfaces convey the relaxed atmosphere of a luxury lounge. Tranquility and reduction are fundamental aesthetic values in the brand’s new flagship model.
Inside the large sedan, the lines flow elegantly and create clear, horizontally oriented volumes. They accentuate the freedom that the new A8 offers its passengers. The applications in the sculptural instrument panel are available in a choice of wood veneer or piano finish and create the wrap-around – the large arc running across the door trims and into the rear. This zone accommodates the air vents, which are concealed by shutters when inactive. If the automatic air conditioning is set directly to the interior, the shutters are slid up and away electrically while the air vents extend out a few centimeters.
In the lower section of the instrument panel, the central 10.1-inch touchscreen display with black panel technology blends almost invisibly into the high-gloss black trim. Depending on the equipment, it is in slate gray with a technical structure or in dark, matt-brushed aluminum. On the center tunnel console, which continues the black-panel look, there is a second touchscreen display measuring 8.6 inches. The buttons on its bottom edge optionally blend in with the display look to present a continuous touchscreen surface. They provide the user with tactile and acoustic feedback as from a conventional switch. The same applies to the light switches and the controls on the air vents.
As an option, two LED light guides each on the center tunnel, instrument panel and in the doors create a fitting lighting atmosphere in the interior. They create contour and ambient lighting with separate brightness and color control as an elegant way of accentuating the design lines. On the A8 L, the backs of the comfort customized contour front seats also incorporate a contour light strip. The newly developed Matrix LED reading lights each with seven LEDs provide optimum illumination. The passenger can precisely control the brightness, size and focus of the light cone with the rear seat remote control.
Natural and authentic: colors and materials
The interior of the new A8 is notable for its authentic materials. Some of the real wood inlays are open-pored and feel natural to the touch. For its leathers, Audi fundamentally steers clear of chrome tanning – its top-quality unique pieces are natural materials tanned with plant-based products, can breathe actively and are hand-crafted. The comfort head restraints are enveloped in soft, velvety Cocoon leather, a new upholstery of the highest grade. The harmony of the materials and their naturalness create a new, contemporary impression of luxury. They radiate craftsmanship down to the finest detail, giving them bespoke character; the same applies to the perforation in the seat upholstery.
There are eight material and color schemes in the new A8, culminating in Audi design selection. For the upholstery, the choices are Verdi cloth and the leather grades Valetta, Valcona and Unicum. These can be supplied in the new colors pearl beige, metropolis gray and merino gray, for example. On selected equipment items, contrasting stitching adds an extra highlight. In addition, depending on version the instrument panel comes in a two-color design. There are various veneers, ranging from beech and eucalyptus to burr walnut and black piano finish. Finally, those wishing to enhance their A8 to their personal taste will find an extensive selection of other exclusive veneers, colors, materials and leather upholstery and trim in the Audi exclusive program.
Even more efficient: engines with MHEV technology
At its market introduction in Europe, the new Audi A8 will start out with two extensively reengineered V6 turbo engines, a 3.0 TDI with 210 kW (286 hp) and a 3.0 TFSI with 250 kW (340 hp). The two V8 versions will follow: The 4.0 TDI develops 320 kW (435 hp), and the 4.0 TFSI has a power output of 338 kW (460 hp). Also appearing later on is the W12 for the A8 L, developing 430 kW (585 hp). All engines offer supreme refinement, ample performance and high efficiency. The new mild hybrid technology (MHEV, mild hybrid electric vehicle) drives down fuel consumption even further – by as much as 0.7 liters (0.3 US gal) of fuel per 100 kilometers (62.1 mi) in real driving conditions. Particulate filters for the gasoline engines will follow in 2018.
Audi’s MHEV technology is based on a newly developed 48-volt primary electrical system – it supplies the 12-volt system that now becomes an electrical subsystem. The 48-volt system is fed by a belt alternator starter (BAS) connected to the engine’s crankshaft by the belt drive. A lithium-ion battery positioned safely beneath the luggage compartment floor serves as the storage unit.
The new drive combines efficiency with comfort in a very special way: Thanks to the higher voltage, the new A8 can coast along silently in a speed range from 55 through 160 km/h (34.2 through 99.4 mph). The automobile then proceeds with zero emissions for up to 40 seconds with the engine off altogether. As soon as the driver steps on the gas again, the belt alternator starter prompts a swift but soft restart. In addition, start/stop operation is actually active from 22 km/h (13.7 mph). When the brakes are applied, the BAS can recover up to 12 kW of power, again helping to reduce fuel consumption.
Power and spontaneity: the 3.0 TDI and 3.0 TFSI
Both V6 engines are high-tech units. The 3.0 TDI develops 210 kW (286 hp) from a displacement of 2,995 cm³. Many areas have been extensively reengineered, such as its very sophisticated thermal management. With 600 Nm (442.5 lb-ft) of torque across a rev range from 1,250 to 3,250 rpm, it develops hefty traction. The 3.0 TFSI with a displacement of 2,967 cm³ develops 250 kW (340 hp) and likewise achieves its peak of 500 Nm (368.8 lb-ft) extremely low down the rev range, between 1,370 and 4,500 rpm. Its exhaust end lies inside the 90° vee, so the short gas paths and the twin scroll charger promote responsiveness. Its combustion principle makes the V6 gasoline engine especially efficient. To support it, the Audi valvelift system (AVS) adjusts the intake valve opening times and stroke in two stages based on demand.
Performance and culture: the 4.0 TDI and 4.0 TFSI
Even more performance is on tap with the two four-liter, eight-cylinder engines that are to follow in 2018 – the 4.0 TDI with 320 kW (435 hp) and the 4.0 TFSI with 338 kW (460 hp). They share fundamental technical principles, such as biturbo technology and the Audi valvelift system (AVS). When the gasoline engine is being driven with restraint, the AVS deactivates cylinders 2 3, 5 and 8 by closing their intake and exhaust valves. This reduces fuel consumption and promotes efficiency. On the diesel, AVS operates one exhaust valve in each cylinder. It therefore manages the two turbochargers, which – unlike on the TFSI – are switched sequentially. For better filling of the combustion chambers, there is likewise an intake AVS on the TDI.
Under load, the 4.0 TFSI develops a characteristically sporty sound that is completely free from interfering frequencies. On the V8 gasoline engine, the e-tron and the W12, Active Noise Cancellation (ANC) eradicates these. The system sends specific anti-noise to the sound system’s loudspeakers. In addition, the V8, W12 and 3.0 TDI are fitted with active engine mounts that inhibit the transmission of vibrations to the vehicle body. They, too, generate out-of-phase counterimpulses – their effect is particularly marked when idling.
Exclusive top engine: the W12
The W12 will follow in 2018 in the new Audi A8 L as the supreme, highly refined top engine version. With its two twin scroll turbochargers, it develops 430 kW (585 hp) from a displacement of 5,950 cm3. Its 800 Nm (590.0 lb-ft) of torque is available constantly between 1,300 and 5,000 rpm. Like the 4.0 TFSI, the twelve-cylinder engine features COD (cylinder on demand) technology. At low loads and engine speeds, it shuts down the left-hand cylinder bank to trim fuel consumption.
Comfort and stability: the power transmission
All engines in the A8 deliver their power to a newly developed eight-speed tiptronic. Not only does it change gear swiftly and smoothly; it also operates highly efficiently. An rpm-adaptive torsion damper (RTD) with a centrifugal force pendulum compensates for undesirable vibrations in the engine. This permits efficient driving from an engine speed range as low as 1,000 revolutions per minute.
The improved tiptronic is now for the first time equipped with an electric oil pump – it is activated whenever the large sedan is coasting with the engine off. As soon as the new A8 is coasting and its engine is either deactivated or idling, a clutch in the central transmission is disengaged to interrupt the power flow. For a faster buildup of pulling power, especially after coasting with the engine deactivated, the engineers in partnership with ZF optimized the engagement logic applied in the gearshift process.
The transmission control in the new A8 can for the first time recognize stop & go situations. It now modifies the driving strategy with the emphasis on comfort; for example, it avoids unnecessary gearshifts or starting in second gear. The driver can let the automatic transmission do the work automatically in the E, D and S modes, or can take charge of controlling it in M mode. Selector lever commands are all transmitted electrically.
quattro permanent all-wheel drive is standard in the new Audi flagship model. In normal driving conditions, its self-locking center differential distributes torque between the front and rear axle in a 40:60 ratio. If slip occurs at one axle, it directs up to 70 percent of the drive torque to the front and up to 85 percent to the rear. Handling benefits from wheel-selective torque control whenever a committed driving style is adopted. The intelligent software function brakes the two wheels on the inside of a bend slightly before they can begin to spin.
Customers can also choose the optional sport differential in conjunction with the two V6 and V8 engines as well as the W12. When cornering dynamically, this redistributes the torque between the rear wheels as required – enhancing traction, stability and dynamics. The driver can view a display of the percentage drive torque per wheel in the MMI of the new A8. Compared with the previous model, the sport differential is around one kilogram (2.2 lb) lighter and offers even faster, higher-precision control. Its management uses the latest generation of the electronic suspension platform (ESP) and is incorporated into the Audi drive select handling system. This allows the driver to experience a range of chassis settings in one and the same car. The operating principle of the participating systems can be set using the comfort, auto, dynamic, efficiency and individual modes.
Intelligent and highly integrated: the electronic suspension platform (ESP)
The second generation of the ECP features in the Audi A8. It brings together all signals and data relating to the suspension in a single control unit and offers a new function with the integral driving dynamics controller. It influences the dynamic all-wheel steering, sport differential and active suspension – a new level of integration in the luxury class. The sensors also detect the driving status, such as understeering or oversteering, and the road surface friction. The control unit uses the calculated values to adjust the above components as well as the damper control and air suspension. The customer experiences this in the form of optimum cornering behavior, improved transverse dynamics and ideal ride comfort. The combined algorithms allow faster, more in-depth coordination of the individual systems.
Large and powerful: the wheels and brakes
The powerful brakes with their aluminum fixed calipers on the front axle also make a big contribution to driving safety. The detail features vary from one engine version to another. For the V8 models and the W12, there is the option of perforated carbon ceramic discs measuring 420 millimeters (16.5 in) in diameter. Each caliper on the front wheels has ten brake pistons, or six pistons on the standard version. Electronic Stabilization Control provides even more precise control than in the previous model.
The wheel range starts with an aerodynamically optimized 17-inch wheel, going all the way up to size 9 J x 21 with 275/35 tires. If any of the wheels are not properly tightened, a function integrated into the Electronic Stabilization Control alerts the driver promptly. The loose wheel warning is standard, and unique in the market.
A new level of intelligence: Audi AI
Audi AI is the umbrella term for a new generation of high-end assistance technologies extending all the way up to highly automated driving. Three of them will be available for the first time in the new A8 – the Audi AI traffic jam pilot, the Audi AI (remote) parking pilot and the Audi AI remote garage pilot.
World debut for highly automated driving: the Audi AI traffic jam pilot
With the Audi AI traffic jam pilot, the brand with the four rings presents the world’s first system that enables highly automated driving at Level 3. The car takes over the task of driving in certain situations. Unlike at Level 2, the driver no longer needs to monitor it permanently. They must merely be capable of taking back responsibility whenever the system prompts them to.
The driver activates the traffic jam pilot with the AI button on the center console. On freeways and highways where a physical barrier separates the two carriageways, the system takes over the driving task if the car is traveling at less than 60 km/h (37.3 mph) in nose-to-tail traffic. The traffic jam pilot manages starting, accelerating, steering and braking. It can also handle critical situations such as vehicles cutting in closely in front. The signals that the traffic jam pilot needs for highly automated driving are supplied for instance by the central driver assistance controller (zFAS).
With the traffic jam pilot active, the driver can relax. They can take their hands off the steering wheel permanently and, depending on national laws, focus on a different activity that is supported by the car, such as watch a TV program on the 10.1-inch display in the center console. In this instance the Audi virtual cockpit supplies abstract representations that symbolize the motion and surroundings of the new A8.
During highly automated travel a small camera in the driving area detects if the driver tires or falls sleep. If that happens, a multi-stage warning is given. As soon as the speed rises above 60 km/h (37.3 mph) or the line of vehicles breaks up, the traffic jam pilot informs the driver that they need to take charge of driving once again. If they ignore this prompt and the subsequent warnings, the new A8 is braked to a standstill. The introduction of the Audi AI traffic jam pilot means the statutory framework will need to be clarified in each individual market, along with the country-specific definition of the application and testing of the system. The brand’s high quality standards are equally applicable in the realm of highly automated driving. In addition, a range of approval procedures and their corresponding timescales will need to be observed worldwide. Audi will therefore be adopting a step-by-step approach to the introduction of the traffic jam pilot in production models.
Park and watch: the Audi AI remote parking pilot and garage pilot
With the Audi AI remote parking pilot and the Audi AI remote garage pilot, the A8 drives independently and without a driver into a parallel or right-angle parking space in several maneuvers, or forward into a garage. Both systems access the steering, accelerator, brakes, tiptronic and also the optional dynamic all-wheel steering.
What is new here is the driver is outside the car throughout the entire parking maneuver. They start the maneuver from their smartphone by pressing the Audi AI button in the myAudi app. To monitor it, they hold it pressed and watch a live display from the car’s 360 degree cameras on their device. Once the parking maneuver is over, the system automatically engages the tiptronic P position and switches off engine and ignition. When ready to drive off, the driver can start their A8 by smartphone and drive it out of the parking space or garage again. If the driver is still behind the wheel, they also have the option of activating the parking pilot using the AI button in the center console. Like the AI button in the myAudi app, they again need to hold it pressed throughout the entire process.
The Audi AI (remote) parking pilot and the Audi AI remote garage pilot function intelligently and conveniently. For instance the sedan can also be steered accurately into a garage if it needs to describe an arc. Inside the garage, the A8 can approach very close to the walls and obstructions such as bikes – or it will interrupt entering if there is not enough space for the car. This special function benefits especially from the innovative laser scanner and is not available in any other competitor model.
Full HD: the Audi virtual cockpit
As well as the MMI touch response displays and hybrid voice control, the new Audi A8 has a third control level, the multifunction steering wheel. The driver uses it to call up all driving and vehicle information; they can also activate the primary infotainment functions. The information is routinely displayed in the Audi virtual cockpit. Its 12.3-inch TFT monitor, which is fed by a separate K1 computer unit by NVIDIA, provides a brilliant full HD resolution of 1,920 x 720 pixels. The driver can choose between two interfaces, both of them with a modern look. In the classic view, the virtual instruments are similar in size to analog displays. Between them is a window in which the navigation map or telephone, radio and audio lists are displayed. In Infotainment mode, this window is maximized and the speedometer and rev counter are correspondingly reduced in size.
Floating image: the head-up display
The optional head-up display projects information relevant to the driver as symbols and numbers that can be quickly perceived within the driver’s direct field of view, including speed, navigation messages and information from certain assistance systems. A TFT screen and two aspherical mirrors project it onto the windscreen in a field measuring 217 x 84 millimeters (8.5 x 3.3 in). It appears to hover in a window about 2.3 meters (7.5 ft) in front of the driver. Because the eyes are focused for distance vision, they can register its content especially fast, minimizing any driver distraction.
Indulgent comfort: the seats
The lounge character presented by the interior of the new A8 owes much to the newly designed seats. They are much lighter than on the previous model – the front seats alone trim over four kilograms (8.8 lb) off the weight. Glass fiber-reinforced polymer (GFRP) is used in the rear seats. At both the front and rear, the structure of the seat cushions and backrests with a variety of shaped, comfort and flexible foam layers afford excellent comfort and good lateral support.
Audi supplies the front seats in various different versions. The top version is the comfort customized contour seat. In addition to pneumatic seat and backrest side bolster adjustment, it also comes optionally with heating and ventilation, each with separate three-stage control. The developers have also significantly extended the optional massage function. In each backrest there are 16 small bubble-shaped air pockets, in threes on top of each other. They massage the entire back in a choice of seven programs and three intensity levels. A small compressor on each seat exerts up to 0.5 bar of pressure.
Both A8 body versions – standard and extended wheelbase alike – are built as standard with a three-person rear seat, optionally with through-loading facility or cool box. The outer seats can also be supplied optionally with heating, plus electrical adjustment of the fore/aft position, seat angle and backrest angle. The lumbar support is then pneumatically adjustable. It can likewise be supplied with a massage function with 18 triple air pockets per seat. Comfort head restraints and rear roller blinds add the finishing touches to a sense of relaxed travel. Audi also supplies the same adjustment options as for the three-person rear seat bench for the individual seats in the A8 L with long, continuous center console. It provides an armrest and large storage compartments.
First-class travel: the relaxation seat
The first-class solution in the new A8 is the relaxation seat at the rear right. Its occupant can recline it and rest their feet on an electrically folding surface on the backrest of the special front passenger seat. This provides the option of having the feet warmed and massaged with multiple settings. There are three power levels, two programs and three foot sizes to choose from, also providing full-surface reflexology. The rear passengers can relax their heads against the soft comfort head restraints, which here have electric height adjustment. The relaxation seat package comprises the comfort customized contour seats with ventilation and massage, the long center console with double folding table, the rear seat remote operating unit, Rear Seat Entertainment and four-zone deluxe automatic air conditioning. The thermal comfort packages, a supplementary option, heat the armrests in the doors, the front and rear center armrests, as well as the steering wheel.
Compact-format operating convenience: the rear seat remote
Audi has created the compact rear seat remote especially for the rear compartment. This device resembling a smartphone allows the passengers to operate an array of climate control, seat, lighting, adjustment and media functions via its touchscreen. The device also acts as a convenient remote control for the Audi tablet if the latter is fixed to the reverse of the front seat. Communication with the MMI navigation plus is by Wi-Fi on the new 5 GHz band.
The rear seat remote has a 5.7-inch touchscreen display in OLED technology with full HD resolution. Its aluminum case is very high-quality, and the technology with the T40 processor from NVIDIA is made to withstand the very high temperatures that may be encountered inside the car. The rear seat remote clips into and is charged in the center console on the four-seater Audi A8 and the center armrest in the five-seater. Depending on the rear equipment specification, it is supplied as standard or an option.
The two Audi tablets of the Rear Seat Entertainment are equally exclusive and sturdy. Their 10.1-inch screens have a full HD resolution and the processor is by NVIDIA. The Audi tablets communicate with the MMI navigation plus and the rear seat remote by Wi-Fi. Their users can enter navigation destinations, select media or surf over a Wi-Fi hotspot. The Audi tablets also provide access to the world of Android, complete with the Google Play Store. After a journey, they can continue to be used away from the car on any Wi-Fi network.
As you choose: new phone solutions
It also could not be more convenient to handle phone calls in the new A8. The sedan allows two mobile phones to be connected and used alternately. The MMI navigation plus can save over 4,000 contacts. For the rear, a separate Audi phone box is available for the four and five-seater versions alike. It pairs the passenger’s smartphone wirelessly with the car aerial for guaranteed best reception. It also charges it inductively using the Qi standard. In conjunction with the rear seat remote operating unit, the rear passenger can in addition make phone calls discreetly.
High-resolution 3D sound: the top sound system from Bang & Olufsen
Audi has three sound system offerings. Topping the bill is the 3D Bang & Olufsen Advanced Sound System, now also available for the first time in the rear. An efficient amplifier controls 23 loudspeakers with 1,920 watts; their neodymium magnets produce an airy, high-resolution sound pattern. Precision-perforated aluminum elements adorn the bezels of the door loudspeakers, while LED light guides emit white light. The lens tweeters in the instrument panel are extended electrically – a modern classic feature of Audi.
Four full-range loudspeakers in the A-pillars and in the roof line take care of the high-level spatial dimension. An algorithm computes the signals for them. It is based on a method that Audi has developed jointly with the Fraunhofer Institute. The sound impression makes the interior a world of acoustic experience where the music unfolds exactly how it was recorded in the concert hall.
As an option Audi equips the new A8 with a digital audio tuner for DAB and DAB+. The optional TV tuner equally operates digitally. Its CI+ module permits reception of encrypted channels via a smartcard.
Clean, fresh air on board: the air quality package
The new Audi A8 offers its passengers a thoroughly agreeable climate including when it comes to air – especially with the optional air quality package. This includes fragrancing distributed non-centrally throughout the interior using the air conditioning system’s outlets. The instrument panel conceals two vials containing a hint of sea breeze or mountain air. The customer can adjust the level of intensity of the fragrancing over four stages. The ionizer is also part of the package. It charges the molecules of the interior air electrically with negative ions. These anions attract dust and similar minuscule particles; these then form mini clusters which fall to the floor so are not inhaled.
In 2018, a particulate measuring sensor will also be introduced for specific markets. It determines the level of particulates in the ambient air and compares this reading with the air inside the A8. Filter efficiency is displayed on the on-board monitor – an important service especially for customers in urban areas.
The standard air quality sensor also detects harmful gases and activates recirculated air mode as necessary. The filter in the four-zone automatic air conditioning eliminates the bulk of these gases and particulates, and also neutralizes many allergens.
