For the first time has been shown in February 1994. А8 — the first-ever car of a class "lux" which is let out by the big series. The car with forward or full quattro a drive, a bearing body from the aluminium alloy made on technology Audi Space Frame® has rich equipment on the basis of electronics and modern technologies.
All-wheel drive updating 2.8 quattro left in 1995. In June of the same year the new engine 3,7 V8 is established. In January, 1996 there is an engine 2,8 V6 30 valves (193 h.p.).
The complete set of all updatings of series А8 is expanded. Till 1996 the conditioner entered into a serial complete set only cars equipped with "eights". Now the conditioner without surcharges can use and owners of cars with 6-cylinder motors. The peredneprivodnyj variant is in addition equipped ABS, four lateral inflatable pillows of safety (plus of a pillow of safety for the driver and the forward passenger).
The new scale of engines of 1997 is, first of all a V-shaped six-cylinder diesel engine with a turbo-supercharging and direct injection. Its working volume makes 2,5 l, and capacity reaches 150 h.p. Steadiness, мощностные characteristics, and also economic indicators put the engine 2,5 TDI in one number with the best motors in the class. Besides it, А8 is issued with the 2,8-litre six-cylinder engine, and also with V-shaped "eight" in working volume of 3,7 and 4,2 l by capacity of 230 and 300 h.p. accordingly. The car can be completed both a mechanical box, and five-step "automatic machine" of firm ZF.
Model S8 represents especially high-speed variant A8 and is equipped by V-shaped "eight" with the capacity raised to 340 h.p. and a mechanical 6-step transmission.
In November 1998 new updating Audi A8 is presented to Germany, in June 1999 there was a model with the increased capacity, in February 2000 — with the new engine 2,5 V6 TDI (180 h.p.).
The car body is completely made of easy alloys on technology Audi Space Frame®. On a frame welded from aluminium profiles, panels from aluminium — wings, a roof, sidewallsы are hung. All details are made of a special aluminium alloy which is not subject to corrosion, easily give in to processing and is better absorb energy of blow. Forward and back suspension brackets independent, четырёхрычажные, collected on a stretcher.
The modernised variant outwardly differs from previous a new lattice of a radiator, modified bumpers and door handles, and also headlights of head light with smooth glass. As a whole differences are a little appreciable. The body design is a little changed.
ESP now enters into serial equipment. Richly issued salon is equipped by pillows of safety in the field of a head for sitting in front and behind. Internal illumination of salon is Anew designed.
Eight-cylinder engines are equipped by new heads with five valves on the cylinder and an inlet path of variable length. As a result capacity of the engine in volume of 3.7 litres has grown to 191 kw, a twisting moment — to 350 Nanometers, and capacity of the engine in volume of 4.2 litres — to 228 kw, a twisting moment — 410 Nanometers.
For reduction неподрессоренной weights and improvements of characteristics of controllability of a drive of wheels also are produced from an aluminium alloy.
The highest technical characteristics differs Audi A8 with a turbodiesel: capacity 150л.с., the twisting moment above 310 Nanometers, and it remains maximum in record-breaking wide range of turns (from 1500 to 3200), makes the fuel expense at speed 90, 120 km/h and in a city cycle — 4,4; 5,7; 8,5 l on 100 km.
German chancellor Gerhard Schrцder has preferred specially made for it длиннобазную Audi A8 to representation cars Mercedes which German chancellors traditionally used.
In 2000 family A8 was added with two new diesel units capacity of 180 and 225 h.p. Now program А8 includes five engines capacity of 180-310 h.p. three of which can be established as on front-wheel, and all-wheel drive chassis. We will especially note the 3,3-litre diesel engine of type V8 first in Europe capacity 225 л.с, which transforms А8 3.3TDI in some kind of "the diesel" express train ideally adapted for economic driving on автобанам. This power unit is completed only With 5-step "automatic machine" and only on the chassis quattro. Its maximum speed reaches 242 km/h, dispersal from a place to 100 km/h — 8,2 with, and the fuel expense in a conditional European suburban rideable cycle — only 7,3 l/100 of km against 8,9 l/100 of km for 260-strong petrol analogue.
The most prestigious is complete set А8 Quattro extended on 130 mm 4,2 with the engine in 310 h.p. the Car can have an exclusive interior and to be executed as «office on wheels».
It is interesting, what even in this class at Audi there is special "sports" version S8. First it was completed only with a mechanical 6-step box, however later there was quite naturally also 5-step "automatic machine" Tiptronic equipped with system DSP, giving the chance "a manual" gear change. Chassis S8 differs 18-inch wheels and more rigid suspension bracket with the road gleam reduced by 20 mm. The car is intended for the men of means preferring personally to operate by the car. Safety and comfort S8 level is rather high.
The technological level of top models Audi steadily raises. Now with an aluminium body the most powerful updating — Audi A8 W12 is offered to admirers of limousines — is equipped by the 6,0-litre 12-cylinder engine capacity of 420 h.p.
