Chronology
Predecessor	Audi V8

The Audi A8 is a four-door, full-size, luxury sedan car manufactured and marketed by the German automaker Audi since 1994. Succeeding the Audi V8, and now in its third generation, the A8 has been offered with both front- or permanent all-wheel drive, with multitronic or tiptronic automatic transmissions—and in short- and long-wheelbase variants. The first two generations employed the Volkswagen Group D platform, with the current generation deriving the MLB platform. After the original model's 1994 release, Audi released the second generation in 2002, and the third and current iteration in 2009.

Notable for being the first mass-market car with an aluminium chassis, all A8 models have utlised this construction method co-developed with Alcoa and marketed as the Audi Space Frame.

A mechanically-upgraded, high-performance version of the A8 debuted in 1996 as the Audi S8. Produced exclusively at Audi's Neckarsulm plant. Unlike the donor A8 model, the S8 has only been available in short-wheelbase form and is fitted standard with Audi's quattro all-wheel drive system.

The Audi A8 (Typ 4D) debuted in Europe in 1994, with factory production commencing June 1994, although it was not until the 1997 model year that it became available in North America. Unlike its predecessor, the Audi V8 model, which was built on an existing steel platform, the A8 debuted on the then-new Volkswagen Group D2 platform, an all aluminium monocoque, marketed as the "Audi Space Frame" (ASF), which helped to reduce weight and preserve structural rigidity. The saloon/sedan was offered in both the A8 (standard wheelbase), and the A8 L extended or long-wheelbase (LWB) version. The A8 L adds 5 inches (127 mm) of rear legroom. Updates to the car in 1997 included the addition of six interior airbags.

For 1997, the new A8 was available with either front-wheel drive (FWD), or the Torsen-based quattro permanent four-wheel drive. The FWD models are powered by a 2.8-litre V6 engine, producing 142 kilowatts (193 PS; 190 bhp), and 3.7-litre V8 engine producing 171.5 kilowatts (233 PS; 230 bhp), while the quattro received a 4.2-litre V8 producing 220 kilowatts (299 PS; 295 bhp).

The A8 is available with standard luxury amenities, including dual-zone climate control, wood and leather interior trim, 14-way power and heated seats, and an enhanced Bose audio system.

In 1999, Audi's flagship received new colours, and restructuring of option packages. The North American "warm weather package" added a solar sunroof which allows the interior ventilation fans to run, keeping the interior cool while the car is parked with the engine turned off. Changes to all models included a larger passenger-side mirror, and a first aid kit located in the rear centre armrest.

In 1999 for the 2000 model year saw a minor front-end restyle, with new, larger, clear headlights, a revised grille, and lower front valance with standard projection fog lamps. On the interior, the seats received a new, horizontal stitch pattern. Also, the 3.7-litre V8 FWD model was dropped, leaving the 2.8 V6 model and the long-wheelbase and short-wheelbase 4.2-litre quattro. These restyled cars also featured revised external door handles and an integrated radio antenna. For 2000, the North American A8 lineup was expanded to include the A8 L.

For 2001, A8 received side curtain airbags. In 2001, Audi introduced its new W12 engine, a compact 6.0-litre unit developed by effectively mating two VR6 engines together at the crankshaft. The engine quickly became available in the A8, though only to European and Asian customers. From its introduction through its discontinuation in 2003, only 750 of the D2 "W12" models were produced. 2001 also marked the debut of the high-performance S8 variant in North American markets.

In 2002, the A8 L received standard xenon high-intensity discharge lamp (HID) headlights, and a heated steering wheel. A tyre pressure monitoring system (TPMS), an updated Symphony II stereo, and new exterior colours were also added. For 2002, all A8 variants received a trunk/boot interior release lever to facilitate escape in the event an individual became trapped within.

Factory production of this generation ceased in September 2002.

Coupe (prototype)

In 1997, IVM Automotive of Munich, Germany built a two-door Audi A8 Coupé. The car was unveiled at the 1997 Geneva Motor Show. Audi contracted IVM to build the prototype, and was considering production of the vehicle. The coupé had a re-engineered aluminium body, shorter than the production A8 saloon. Like the Mercedes-Benz CL-Class, there was no central "B" pillar, giving the car a seamless design with a gradually sloping roofline. The car included custom leather seats which could seat four. Ultimately, Audi decided not to put the A8 Coupé into production, citing lower-than-expected sales figures for the similar BMW 8 Series and Mercedes-Benz S-Class Coupé. Only one A8 Coupé was ever built. The single prototype, painted a colour called "Ming Blue pearl," remains the property of IVM Automotive, and resides in Munich. Its last public appearance was in 2002 on a series of test drives.

S8

Facelift Audi S8 (D2; Europe)

Audi introduced the S8 4.2 quattro into the European market in 1996. The S8 followed the naming convention of other high-performance Audi "S" models such as the Audi A6-derived S6 and was similar in vein of Mercedes-Benz AMG models. In markets such as the UK, the S8 was only available with the automatic transmission. Cosmetically, Audi diferrentiated the S8 from the A8 with solid aluminium alloy door mirror housings, chrome-effect beltline and lower front grille trim, and polished twin exhaust pipes, along with subtle "S8" badging. 14-way power adjustable and heated sports front seats with memory function were fitted as were heated rear seats. Standard alloy wheels were 18-inch cast aluminium alloy "Avus" six-spoke style. After the 1999 facelift, 20-inch polished nine-spoke RS wheels became an option. In 2002, 18-inch nine-spoke RS wheels became a no-cost option.

At the same time of the A8's facelift in late 1999, the S8 received the same cosmetic upgrades. This update marked the release of the S8 to the North American market. Production of the D2 series S8 ended in September 2002.

The D2 series S8 featured an uprated, 250 kilowatts (335 hp) version of the 4.2-litre V8 with four valves per cylinder. From late 1999, Audi increased this to five valves per cylinder with power increased to 265 kilowatts (355 hp) and 430 newton-metres (317 lb⋅ft). From launch in 1996, European-market models came standard with a six-speed manual transmission. A sports-recalibrated version of the ZF 5HP24 five-speed tiptronic automatic, featuring "Dynamic Shift Programme" (DSP) was released a year later and was the only transmission available in most other markets.

A retuned, 20-millimetre (0.8 in) lowered sports suspension included a 30 percent stiffer spring rate and 40 percent more compression damping in the shock absorbers. Speed-sensitive "servotronic" power assisted steering was also standard.

The brakes featured Bosch 5.3 anti-lock braking system (ABS), with electronic brakeforce distribution (EBD), and worked radially ventilated front discs. From 2002, an upgraded Bosch 5.7 electronic stability programme became standard fitment.

Audi A8 (prefacelift; Australia)

The second-generation Audi A8 (Typ 4E) built on the Volkswagen Group D3 platform was introduced in November 2002 in Europe and in early 2003 in the United States. The model was longer than the previous generation, with room for four or five large adult occupants in the cabin, depending on rear seat configuration.

As with the previous version, two body variants of the second generation A8 are offered, the A8 (standard, or short wheelbase), and the long-wheelbase (LWB) A8 L. The A8 L adds 120 mm (4.7 inches) to the rear legroom and 11 mm (0.43 in) to the overall height of the car.

In 2005, new internal combustion engines became available. For European and Asian market customers, the entry-level 3.0-litre V6 engine was replaced with a new 3.2-litre unit featuring Fuel Stratified Injection (FSI), which it shared with the Audi B7 A4 and Audi C6 A6. The top-of-the-line W12 engined W12 version debuted that year, to compete with other flagship 12-cylinder sedans such as the Mercedes-Benz S600 (powered by a twin-turbo V12), and the BMW 760Li (powered by a naturally aspirated V12). The advantage of the W12 engine is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 could only have a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, Audi's 6.0 L W12 is actually a bit smaller by overall dimensions than the 4.2 L V8.

In addition to the added powertrains, Audi restyled the D3 platform A8 range slightly in 2005, giving all variants a taller, wider trapezoidal single-frame grille. The top-of-the-line W12 engined W12 version was the first model to be equipped with this grille; V8 engined models were fitted with the new grille the following year.

The D3 generation A8 introduced the 235 kilowatts (320 PS; 315 bhp) 4.2-litre Turbocharged Direct Injection (TDI) V8 engine (subsequently uprated to 240 kilowatts (326 PS; 322 bhp)) – the most powerful diesel engine Audi has ever offered in a passenger automobile, until the debut of Audi's 6.0-litre V12 TDI engine in the Audi Q7. The engine uses two turbochargers and two intercoolers, with each turbocharger functioning exclusively for one bank of four cylinders. The 2.8-litre V6 FSI, which was recently added to the A8 range, has a 199 g/km of CO₂ emission.

From 2005 or 2006 Audi started offering the optional 1,000 W 14-channel ICEpower Bang & Olufsen sound system.

For the 2008 model year (starting from September 2007), the A8 received a facelift and also received new electronic safety systems. "Audi Side Assist" detects cars in the A8's blind spots. "Audi Lane Assist" helps when the driver attempts to change lanes without signaling first.

For the 2010 model year (starting from September 2009), the A8 W12 and S8 models were discontinued, while the A8 4.2 and A8 L 4.2 remained available for sales.

A8 L W12 quattro Security

It is an armoured vehicle with B6+ and B7 (European standard) ballistic ratings. In includes a W12 engine rated 450 PS (331 kW; 444 bhp) and 580 N⋅m (428 lbf⋅ft), emergency exit system featuring pyrotechnic blown-out doors, fire extinguisher system with spray jets located in the engine compartment, underbody and in the wheel arches; smoke extractor in passenger compartment, run flat tyres, LED flashers in the exterior mirrors. Buyer also offered facility to dispatch two drivers on a special training course.

S8 5.2 FSI quattro

The S8 high-performance sports variant, now called the "Audi S8 5.2 FSI quattro" was announced in the last quarter of 2005 and full production started in June 2006 and ended in 2009.

The S8 includes subtle detailing to distinguish it from its related A8. The trapezoidal "single-frame" grille bears the characteristic Audi "S model" vertical strut detail which are highlighted in a chrome finish. "S8" badging is displayed front and rear, whilst "V10" badges are displayed on each front wing below the side-repeater indicators. The rear boot-lid incorporates a subtle rear spoiler, and the rear is finished with four chromed oval exhaust tailpipes. Adaptive Xenon-plus high-intensity discharge (HID) headlamps include static turning lights, along with "swiveling" dynamic cornering lights. Daytime running lamps are five light-emitting diodes (LEDs) incorporated into a cloverleaf designed reflector, incorporated into the main headlamp housing.

The D3 series S8 features a 5.2 litre all aluminium alloy Fuel Stratified Injection (FSI) four-valves per cylinder V10 petrol engine. This engine is a derivative of the Lamborghini Gallardo's original 5.0-litre Lamborghini V10, which was also developed under the Volkswagen Group ownership. On this Audi-only variant, compared to the Lamborghini engine, it features a longer stroke and wider bore—which increases the displacement of the engine, and produces more torque at lower revs, making it more suitable for the larger and heavier full-sized luxury Audi application. It produces 331 kilowatts (444 hp) and 540 newton-metres (398 lb⋅ft) of torque. The S8's version has its bore whittled out an additional two millimeters, increasing the displacement from 5.0 to 5.2 liters. It also has Audi's direct-injection system, called FSI. Maximum output is down from 493 horsepower at 7,800 rpm in the Gallardo to 444 at 7,000 rpm in the S8, and torque is up 22 pound-feet (398 pound-feet total), peaking 1000 rpm earlier at 3500 rpm.

Facelift interior

A sports-optimised ZF 6HP26-A61 six-speed tiptronic automatic transmission with "Dynamic Shift Programme" (DSP) and "sport" mode, with steering wheel mounted paddle-shifters, is the only offering. Output is transmitted via Audi's quattro all-wheel drive system, initially using the Torsen T-2 50:50 dynamic centre differential, and from 2007 for the 2008 model year, utilising the Torsen T-3 asymmetric dynamic centre differential, with a "default" torque distribution of 40 percent to the front axle and 60 percent to the rear.

Audi's factory performance claims for the V10 S8 indicate a 0 to 100 kilometres per hour (0.0 to 62.1 mph) time of 5.1 seconds whilst consuming 98 RON unleaded petrol. The S8 has similar performance to Audi's own top-of-the-line A8 L W12, though the W12 is more expensive, has more torque, and built on a longer wheelbase. Compared to the A8 L W12, the S8 has sportier mechanical features such as a firmer suspension, larger wheels, and ceramic brakes. The shorter wheelbase and 10-cylinder engine save weight for better handling, but at 5.4 seconds from 0-60 mph the S8 trails the W12. The S8's top speed is electronically limited to 250 kilometres per hour (155.3 mph).

The S8, like its related A8, utilises a multi-link suspension layout front and rear, with pressurised air springs. However, for the S8, the effective spring and damper rates are noticeably firmer, along with re-engineered suspension mounts.

The brake system consists of radially ventilated discs all round. The discs are clamped with gloss-black painted dual-piston calipers up front, and a single-piston sliding caliper at the rear, coupled to an electro-mechanical parking brake. A Bosch ESP 5.7 (later upgraded to ESP 8.0) Electronic Stability Programme, with ABS, brake assist, EBD complete the brake system. Optional "Audi ceramic" carbon fibre-reinforced silicon carbide (C/SiC) composite front and rear brakes are available, which use radially vented, and floating SGL Carbon discs, with anthracite grey painted six-piston fixed Brembo monobloc alloy calipers. Standard alloy wheels consist of 20-inch "S design" alloy wheels.

The third-generation Audi A8 (Typ 4H) was introduced in Miami on 30 November 2009 and went on sale in November 2010 as a 2011 model.

UK models went on sale in spring 2010. Early models included 4.2 FSI quattro (372PS), 3.0 TDI quattro (250PS), 4.2 TDI quattro (350PS).

It is based on the Volkswagen Group MLB platform, but retains the Audi Space Frame aluminium construction of the previous A8, making it the lightest all-wheel drive car in the full-size luxury segment, while also giving it best-in-class fuel economy.

Initial internal combustion engine options comprise 4.2-litre Fuel Stratified Injection (FSI) petrol and Turbocharged Direct Injection (TDI) diesel V8s, with 273 kilowatts (371 PS; 366 bhp) and 258 kilowatts (351 PS; 346 bhp) respectively. A 3.0-litre V6 TDI with either 184 kilowatts (250 PS; 247 bhp) or 150 kilowatts (204 PS; 201 bhp) will be available later. A 6.3-litre W12 engine will be added in 2010. All engines are mated to the new eight-speed ZF 8HP automatic transmission.

The D4 iteration of the Audi A8 4.2 FSI quattro can do a 0 to 60 mph (0 to 97 km/h) sprint in 5.1 seconds, which is quicker than the past-generation D3 platform Audi S8 5.2 FSI quattro.

US version of Audi A8 3.0 TFSI quattro was unveiled in 2012 North American International Auto Show as 2013 model year vehicle. It featured increased engine power over previous V6 model.

It is anticipated that a third-generation Audi S8 is expected to go on sale in 2011 as a 2012 model, released one year after the all-new 2011 Audi A8. Recent reports suggested that the S8 would use the new 4.0-litre FSI biturbo V8 engine, with 382 kilowatts (519 PS; 512 bhp).

Reception for the D4 series Audi A8 has been positive for its fuel efficiency, light weight, handling, and acceleration.

A8 L Prototype (2011)

It is a prototype vehicle demonstrating long-term evolution (LTE) broadband technology. Developed in collaboration with Alcatel-Lucent, the car’s mobile broadband connection is a fourth generation (‘4G’) technology with data transfer speeds of up to 100Mbps.

A8 L Security (2011–present)

The A8 L Security features a core safety cell made from hot-formed armoured steel, aramide fabric, ceramics, special alloyed aluminium and multilayer glass. The car receives a high level of armoring, an emergency exit system, and a ballistic protection rating of VR7 – strong enough to, according to Audi, withstand a military hand grenade attack. In certain areas, the armoring on the Audi A8 L Security complies with the criteria for class VR 9 and VR 10.

First model included a W12 engine rated 500 PS (368 kW; 493 bhp) and 625 N⋅m (460.98 lbf⋅ft)@4750rpm, with delivery began in late summer 2011. An additional engine model with improved fuel efficiency went on sale in 2012.
