Chronology
SuccessorAudi A8

The Audi V8 (Typ 4C) is a four-door,

quattro system with an automatic transmission. Early cars used 3.6-litre V8s, while later cars featured a 4.2-litre version of the engine. The Audi V8 was replaced by the Audi A8
in 1994, although the A8 was not marketed in North America until 1996.

The competition model of the Audi V8 won back-to-back Deutsche Tourenwagen Meisterschaft driver's titles in 1990 and 1991, with the championship winners being Hans-Joachim Stuck and Frank Biela respectively.[1][2] Audi was the first company to win back-to-back DTM titles.[2]

Overview

Standard features for the Audi V8 included a

quattro permanent four-wheel drive system.[4] A five-speed (later in production six-speed) manual transmission was also available.[5][6]

The Audi V8 had a

flagship' car and included a number of luxury features as standard equipment, including leather seating and Audi's quattro all wheel drive system[3] (see standard features list).[8] The Audi V8 created a new elevated image for the company, providing a viable alternative to established competitors such as Mercedes-Benz and BMW.[8] In this regard, the car was a cornerstone in developing the history of the Audi marque as it is today.[8]

Factory production commenced in October 1988, and ceased in November 1993,[3] although sales of completed vehicles continued in 1994. It was replaced by the Audi A8 in 1994.[9][10][11]

Body style

The Audi V8 used an enlarged version of the bodyshell from the Typ 44

bumpers and headlights, all-red tail lamps, 12 mm extended wheelbase, wider track, pronounced fenders, and more wood trim in the interior. Furthermore, only alloy wheels were offered, ranging from 15 to 17 inches.[12][13]

In addition to the standard-length model, there was also a long wheelbase (LWB), ('Lang' in German) version of the V8 (refer to the infobox for differences in dimensions). It was assembled at Steyr-Daimler-Puch factory in Graz (see production figures). This tradition would continue with the A8, offered in "A8L" format[12] (though only in year 2010 A8L reached the size of the V8L).

A once-off experimental Avant (estate) version was built for the wife of former Audi CEO

Ferdinand Piech
. This car is no longer on display at the Audi Forum Ingolstadt, but in storage in Neckarsulm. [12][14]

Powertrain

viscous fans on earlier cars. This not only provided forced airflow for the engine coolant radiator, but also for the smaller engine oil cooler.[7]

Audi's 'trademark'

quattro permanent (or semi-permanent, dependent on gearbox type) four-wheel drive system was the only offering for the drivetrain.[4] This normally distributes the engine torque as a 'default' 50:50 between front and rear axles, but can automatically dynamically apportion up to a bias of 20:80 to 80:20 front and rear.[4] The automatic transmission utilizes a hydraulically controlled multi-plate clutch to apportion drive between front and rear axles,[4][12] whereas the manual transmission variants utilize a Torsen type 1 Torque Sensing center differential.[4] The rear axle final drive unit contains a Torsen type 1 Torque Sensing differential, instead of the more common hypoid open differential.[4][12]

Engines

1993 Audi V8 4.2 (US) with chrome 'V8' badge

Both available engines used a

intake manifold-sited electronic fuel injectors, fed from two common fuel rails (one per cylinder bank), and were sequentially 'fired' or activated in accordance with the engine's firing order. Whilst the 3.6 V8 was able to use 95 RON (91 AKI) fuel, for the 4.2 V8, the more expensive 98 RON (93 AKI) 'SuperPlus' unleaded was required in order to achieve the quoted power output.[15] The usage of 95 RON in the 4.2 V8 resulted in a lower power output, as well as increased fuel consumption.[15]

At the initial launch of the Audi V8, the only offering was the 3.6-litre powerplant, which displaced 3,562

PS; 247 bhp)[3] at 5,800 revolutions per minute (rpm),[9] and generated a torque turning force of 340 newton-metres (251 lbf⋅ft) at 4,000 rpm.[10] In August 1991, Audi introduced a 4.2-litre engine, displacing 4,172 cubic centimetres (254.6 cu in),[16] to complement the choice of the existing 3.6-litre V8. This shared many components from the 3.6 V8, and the 4.2 unit was identical to the optional V8 used in the Audi S4 (aka Ur-S4), sharing the same rated outputs and ABH identification code. Like the 3.6 V8 model, the existing four-speed automatic gearbox remained available. However, a new six-speed manual gearbox replaced the five-speed manual.[3] This powerplant is identified by chrome 'V8' badges on the front grille and at trunk lid, where in some cars also '4.2 quattro' badge is present.[17]

Motorsport

Audi V8 DTM

Audi developed a

1992.[2][23][25]

For the

forged and bent from the original 90° crossplane part as used in production model. The DTM organisers found this highly modified crankshaft deviated from original homologated standard crankshaft, and therefore deemed it illegal. Audi subsequently withdrew from the championship.[25]

During its presence at DTM the Audi V8 competed with much smaller and about 300 kg (661 lb) lighter

BMW M3, and slightly smaller Opel Omega 3000. None of those cars were equipped with V8 engines or 4-wheel drive.[26]
