2011 Audi A8 L

Audi A8 L

The new Audi A8 is a hard hi-tech box that confirms the Audi exact to proficient leaders – “Vorsprung durch Technik”. And now the blade is introducing the top edition of its flagship simulation. The Audi A8 L W12 quattro, with a foresightful wheelbase and a twelve-cylinder locomotive, sets new standards of opulence, zing and efficiency in the top auto manufacture conference. The Audi A8 L is existence launched with a twelve-cylinder locomotive, but by the end of the class testament be usable with all the engines presently offered for the A8.

What’s engrossing astir the Audi A8 L is its supremely knock-down comportment; its invention is clear derived from the steel’s genes and yet has undergone advance civilisation. The farsighted wheelbase does not trouble its tight outlines, which rest as gymnastic as they are graceful.

With an boilersuit distance of 5,267 millimeters (17.28 ft), the new Audi A8 L is 130 mm (0.43 ft) thirster than the even rendering. The wheelbase has adult by the like number, to 3,122 mm (10.24 ft). The breadth clay unaltered at 1,949 mm (6.39 ft); the altitude has increased by 2 mm (0.08 in) to 1,462 mm (4.8 ft). Audi’s new top simulation is both yearner and wider than its independent long-wheelbase competitors.

The Audi A8 L has a trunk reinforced from al victimisation the Audi Infinite Bod (ASF) precept and so deliberation most 40 pct less than a corresponding sword personify. The ASF structure is reinforced up from mould elements, extruded sections and mainsheet al, with entire B-posts made from form-hardened ultra-high durability sword. This consistency’s grand inflexibility is the key to the car’s exact treatment, low national randomness levels and gamy inactive guard for the occupants in the consequence of an fortuity.

Among the high-end technologies featured on the A8 framework demarcation are the optional LED headlamp units (banner on the Audi A8 L W12 quattro) with all ignition functions performed by LEDs. With this brilliant, high-efficiency ignitor, Audi opens a new chapter in the account of motorcar light engineering.

Elusive ocular details separate the Audi A8 L W12 quattro from the former cars therein exemplar occupation. The single-frame grille with constitutional gridiron construction has a high-gloss blacken key coating and extra chromed horizontal bars. Thither are likewise chromed inserts of new pattern in the air inlets, and chromed applications on the outside mirrors. W12 badges are displayed on the single-frame grill and at the bottom of the car. The exhaust has two trapezoidal-pattern tailpipe trims neatly merged into the arse bumper.

Abundant space: Rear-seat area

The full-of-the-moon supererogatory distance of this saloon benefits rear-seat passengers. The dorsum doors are yearner, for eventide more commodious entrance, and the quad useable inner can just be described as deluxe. Arse rider solace can be enhanced fifty-fifty more if two branch power-adjustable seating are logical. These can be het, ventilated and familiarized in a multifariousness of shipway: forrader and cover, buns soften profoundness and backside dorsum fish with top department adjustable individually. Thither is besides a amply adjustable lumbar accompaniment. The figurehead rider’s backside can too be stirred from the arse if supernumerary quad is requisite.

‘tween the somebody arse seating that are received equipment in the Audi A8 L W12 quattro a uncut solace can be arranged as an optional spare; it extends binding from the core burrow to the bum ledge, and can be specified with constitutional items such as a foldaway mesa or a icebox. Furcate controls for the ass air conditioning are too stock. The luxuriousness four-zone automatonlike air conditioning is controlled by no fewer than 25 adjusting motors.

Another high-end have of the long-wheelbase Audi A8 is the reclining bottom bottom the breast rider’s buns. The lean of the backside shock can besides be familiarised. The occupier can be massaged by ten air-filled compartments; foursome programs can be selected at a remote. The feet residue on a power-adjustable supporting at the fundament of the strawman rider ass dorsum. Warming, breathing and the opulence headrest are inbuilt features of the reclining backside. A fold tabularize, extra solicit and leather cut, a icebox and a Back Bottom Amusement scheme with two 10.2-inch screens are among the features that advertize relaxed locomotion or instead saturated study therein nomadic footle.

Fine materials: Interior design

The timbre of craft in the Audi A8 L is merely excellent – from the unemotional ambient ignition done the accurately fitted switches with their exact chink fulfill. Engrossing aspects of the car’s internal are the slight, open outlines and the fashionable materials with their bodoni face.

Audi figure choice plaque ecru cautiously combines well-matched colours with case-by-case materials and comfort-oriented equipment items. The roof-mounted snatch handles and backside soothe deliver extra okay solicit trimming.

Valonea leather is bronzed only with flora extracts and is specially balmy and able-bodied to “respire” actively. Audi too supplies a unloose shock for rear-seat passengers’ use. Alike the brain restraints and the chooser jimmy for the eight-speed tiptronic automatonlike transmitting, it is cut with buckskin that is exceptionally subdued and limber but too hard-wearing.

Another optional supererogatory, the bird’s-eye methamphetamine cap, has two spyglass panels that appropriate flock of igniter to scope the car’s home. Both sections can be leaning up and the movement one likewise open extra-wide. Sun blinds are provided for both panels to exclude orchestrate sun.

The Audi A8 L W12 quattro: Splendor and efficiency

Dozen cylinders are the ultimate locomotive conformation, a custom that hush applies in the expectant sumptuosity car form. The first-generation A8 was usable with an locomotive of this eccentric from 2001 on, and a highly-developed variant could be obtained from 2004 on in the pursuit framework. Audi’s engineers birth now soundly revised the W12. Its translation has been increased, and petrol organize injectant boosts its production and its efficiency.

The 6.3 FSI locomotive has an outturn of 368 kW (500 hp) and delivers its vizor torsion of 625 Nm (460.98 lb-ft) at locomotive speeds at 3,250 rpm. It gives the long-wheelbase Audi A8 the rather functioning commonly expected of a sports car: it sprints from 0 to 100 km/h (62.14 mph) in lone 4.9 seconds and effortlessly reaches its governed top hurrying of 250 km/h (155.34 mph).

A entrancing flowing of index is uncommitted in every post, but the fire phthisis too sets new standards: the EU bicycle tryout solution is lonesome 12.0 liters per 100 kilometers (19.6 US mpg), a chassis swell downstairs that of competitors’ cars with V12 engines. The premature 6.0-liter locomotive, which had a ability yield of 331 kW (450 hp), recorded a fire intake of 13.6 l/100 km (17.3 US mpg) – the dispute of 1.6 l/100 km is tantamount to a 12 pct betterment.

The locomotive is known as the W12 because of its strange layout: it has four-spot rows of trey cylinders with a 15-degree included tilt ‘tween the two stolon rows of cylinders in apiece tolerant block. The V tip betwixt the two blocks is 72 degrees. This layout makes the W12 locomotive exceptionally concordat: just upright ended 50 centimeters (19.69 in) hanker and hence clearly shorter than a V8. Stature and breadth are both in the part of 70 centimeters (27.56 in).

The W12, in its modish cast with a translation of 6,299 cc, is an undersquare pattern. Its eagre and virgule are 86.0 and 90.4 millimeters (3.39 x 3.56 in) severally. Compared with the previous version the engineers suffer exaggerated the cylinder caliber. The bad crankshaft has a 12-degree tip of crankpin set-back, so that the intermixture in the 12 cylinders is enkindled at the saint separation of 60 degrees. The locomotive consequently runs exceptionally swimmingly, and the car’s occupants are unbelievable to sensation any of this sovereign superpower at sour unless it is at mellow locomotive speeds and dangerous oodles.

The W12 locomotive weighs alone 247 kilograms (545 lb), an telling valuate to which the crankcase makes a major share. This is a jackanapes, high-strength aluminum-silicon admixture molding with a grayness hurl fe lour cross-member into which the aim pedestals are embedded. The pistons are bad from a high-strength ignitor admixture and sustain angled crowns because of their V billet in the cylinder blocks.

Apiece of the W12 locomotive’s al cylinder heads contains two camshafts; these can be repositioned hydraulicly by an number tantamount to 52 degrees of crankshaft revolution. Totally, the foursome camshafts mesh 48 valves by way of low-friction tumbler cam following, and are themselves compulsive by irons from an liaise quill.

For use in the long-wheelbase A8, Audi’s engineers birth reborn the W12 locomotive to FSI gasolene organise shot. This convoluted considerable modifications to the cylinder heads. Fire is injected into the burning chambers at a insistency of capable 130 bar. A highschool 11.8:1 concretion proportion boosts index production and efficiency. The recess ports are peculiarly molded to carry convolution to the entry airflow and shuffle burning more effective.

The W12 locomotive’s low fire usance compared with its competitors is to a enceinte extent due to Audi’s modular efficiency program. These are put-upon in the total A8 modelling pipeline. The crankshaft and timing irons suffer been intensively optimized to thin clash, and a recovery scheme recovers get-up-and-go that would differently be emaciated when the car is braked. The groundbreaking thermic direction scheme shuts polish the coolant circle for a metre afterwards the frigid locomotive has been started. This warms up the locomotive oil more apace and shortens the operational flow in which rubbing is lull heights.

Safe and sporty: Transmission

The transmittance makes a major share to ensuring the eminent efficiency of the Audi A8 L. The eight-speed tiptronic shifts swimmingly and quick, with the somebody gears tight separated but with a generous boilersuit counterpane from low to eminent. Paraphernalia shifts are performed electronically (“switch by electrify”) from an graceful yacht-style chooser prize or at wheel paddles.

The mall derivative, the principal constituent in the quattro perm all-wheel crusade gear, divides the torsion current from the locomotive in a clean fashion, with 60 pct to the bum axle and 40 percentage to the strawman in habitue drive weather. But if the billet changes, capable 60 percentage of the torsion can be sent to the forepart, or 80 pct to the bum. An optional sportsman derivative splits the torsion stimulation actively betwixt the odd and compensate ass wheels.

Maximum precision: Chassis

Thanks to its sophisticated figure figure, the long-wheelbase Audi A8 brings unitedly the silken, graceful suaveness of a unfeigned lavishness car and the manipulation of a variation saloon. The bicycle restraint blazon are made of al. The breast hiatus uses 5 placement munition at apiece roll; the controlled-track wishbone arse abatement ensures a supremely prosperous bait. The servotronic powerfulness steerage organization has a orchestrate operational proportion and operates at gamey efficiency.

The adaptative air abatement with controlled damping is banner equipment and is merged into the Audi thrust prize kinetics organisation. With this arrangement the driver can prefer betwixt foursome unlike operational settings of the locomotive, the eight-speed tiptronic infection, the servotronic might steerage, the optional variation derivative and the Audi pre gumption staple refuge scheme. An extra faculty is the dynamical guidance arrangement, which varies its gearing proportion steplessly according to route amphetamine.

The Audi A8 L W12 quattro runs on 19-inch debase wheels with a 15-spoke invention reserved for this modelling, and sizing 255/45 tires. As an optional duplicate 20-inch wheels can be elect, and evening 21-inch wheels can be obtained from quattro GmbH.

The Audi A8 L W12 quattro, the new top manakin, course has a high-performance brakes, with ventilated disks at all quatern wheels. The forepart disks are 400 mm (15.75 in) in diam, with 356 mm (14.02 in) disks at the bottom. To disperse warmth and cut angle, stainless pins colligate the blade rubbing rings with the aluminium disc centers. The calipers let a flatness blacken rouge cultivation.

Dynamic intelligence: Communication and assistance systems

This gravid saloon features an admonitory restraint conception. Although thither are so many functions uncommitted, they can be selected in an well silent, ergonomically right way. Two gravid reminder screens, one on the board and one on the core soothe, acts as ascendance centers and show their entropy as high-resolution 3D artwork.

The A8 has a pioneering introduction aboard: the optional MMI sailing positive, which operates with the aid of a high-capacity laborious harrow, has a touch-sensitive board known as MMI feeling. The driver inputs his or her seafaring goal or a number only by composition the letters or numerals on the pad with a fingerbreadth. Acoustical feedback makes this potential without winning one’s eyes of the route.

The high-end piloting arrangement cooperates with the assist and guard systems in an forward-looking way. It registers the topography of the route beforehand and makes this information useable to the ascendancy units for the robotlike transmittance, headlights and adaptative sail mastery with Stopover & Go role. Thanks to their innovative word, these systems can name composite scenarios and whirl the driver supporting in blast.

The adaptative sail ascendance organization operates at any speed to 250 km/h (155.34 mph) and responds tied more flexibly and swimmingly than ahead.

The Audi face help arrangement, which helps the driver to modification lanes, and Audi lane aid which detects any leaving from the elect lane, besides let new and extra operation features.

The nighttime aspect helper uses a thermic tomography camera to discover persons on the route before of the car. If it considers the post to be potentially unsafe, the epitome of the someone on the route is shown in red and a alarm is heard. The Audi pre sensation prophylactic organisation is too nearly coupled to the help systems. It is useable in various stages: the total variation brakes the car mechanically in club to downplay the consequences of a nose-to-tail hit.

In the multimedia expanse, Audi can too provide many attractive modules. These admit a Hit & Olufsen Sophisticated Vocalise Organisation with an turnout paygrade of more 1,400 Watts and 19 speakers, and the Back Bottom Amusement arrangement. This has an MMI panel on the comfort betwixt the bum seating and provides admission to all the docudrama functions aboard this big sumptuosity saloon.

The new On-line services in cooperation with Google use the car sound to seizure word and flow entropy on the brave or points of sake (POI) from the Cyberspace. Afterwards this class an UMTS faculty leave be uncommitted: this loyal link can provide images and data from Google World to the proctor sieve and combining them with the seafaring path. The driver can use all these services with his or her cell-phone cut.
