Audi V8
Template:Use dmy dates Template:For Template:Infobox automobile The Audi V8 (Typ 4C) is a four-door, full-size luxury sedan, designed, manufactured and marketed by Audi in Germany from 1988 to 1993, as the company's flagship. As the first car from Audi to use a V8 engine, it also was the first Audi to combine a 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.<ref name="DTM90"/><ref name="DTM91"/> Audi was the first company to win back-to-back DTM titles.<ref name="DTM91"/>
Overview
Standard features for the Audi V8 included a 32-valve, double overhead camshaft (DOHC) V8 engine<ref name=ETKA/> and a four-speed electronically controlled ZF 4HP24A automatic transmission providing Audi's quattro permanent four-wheel drive system.<ref name=AudiV8.com_trans>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> A five-speed (later in production six-speed) manual transmission was also available.<ref>Template:Cite press release</ref><ref>Template:Cite press release</ref>
The Audi V8 had a galvanized steel body, with a 10-year anti-perforation warranty (against corrosion).<ref name="audifans.com">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Audi V8 was specifically designed to be a top of the range 'flagship' car and included a number of luxury features as standard equipment, including leather seating and Audi's quattro all wheel drive system<ref name=ETKA/> (see standard features list).<ref name=AudiV8.com_overview>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Audi V8 created a new elevated image for the company, providing a viable alternative to established competitors such as Mercedes-Benz and BMW.<ref name=AudiV8.com_overview/> In this regard, the car was a cornerstone in developing the history of the Audi marque as it is today.<ref name=AudiV8.com_overview/>
Factory production commenced in October 1988, and ceased in November 1993,<ref name=ETKA>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> although sales of completed vehicles continued in 1994. It was replaced by the Audi A8 in 1994.<ref name=Motor-Klassik>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=TopCarGuide3.6>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Body style
The Audi V8 used an enlarged version of the bodyshell from the Typ 44 Audi 100 and 200 models,<ref name=ETKA/><ref name=AudiStory.com>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and was based on a stretched version of their Volkswagen Group C3 automobile platform, known either as the D1 or D11<ref name=Motor-Klassik/><ref name=AudiStory.com/> platform. The Audi V8 differed from the Audi 100/200 with a unique grille attached to the hood, new 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.<ref name=AudiStory.com/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
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<ref name=AudiStory.com/> (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. <ref name=AudiStory.com/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Powertrain
Powertrain<ref name=ETKA/> detail of the Audi V8 featured one of two all-new, all-aluminium alloy engines – both petrol engines, and both in V8 configuration with 32 valves (four valves per cylinder) with dual valve springs, and four overhead camshafts (DOHC).<ref name=AudiV8.com>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The design set the pattern for future Audi-developed Volkswagen Group V8 engines. In addition to using an all-aluminum alloy cylinder block (when the established material was grey cast iron), the camshafts were driven using a hybrid method. A rubber/kevlar toothed timing belt, driven from the front of the crankshaft operated only the exhaust camshaft in each bank. The inlet camshafts were then operated via a simplex roller chain from the exhaust camshaft – the right bank, (cylinders 1–4) at the rear of the engine, and the left bank (cylinders 5–8) at the front of the engine, immediately behind the timing belt. This method reduced the complexity of the timing belt layout, and as a result, required fewer components, such as idler rollers and guides, and led to easier and less costly maintenance of the timing belt and associated components. The intervals for changing the timing belts varied; the 3.6 V8 (PT) required changing every Template:Convert,<ref name=AudiV8.com/> whereas the 4.2 V8 (ABH) had a longer interval at Template:Convert.<ref name=AudiV8.com/> A thermostatically controlled electric cooling fan also became standard, replacing the engine-driven viscous fans on earlier cars. This not only provided forced airflow for the engine coolant radiator, but also for the smaller engine oil cooler.<ref name="audifans.com"/>
Audi's 'trademark' quattro permanent (or semi-permanent, dependent on gearbox type) four-wheel drive system was the only offering for the drivetrain.<ref name=AudiV8.com_trans/> 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.<ref name=AudiV8.com_trans/> The automatic transmission utilizes a hydraulically controlled multi-plate clutch to apportion drive between front and rear axles,<ref name=AudiV8.com_trans/><ref name=AudiStory.com/> whereas the manual transmission variants utilize a Torsen type 1 Torque Sensing center differential.<ref name=AudiV8.com_trans/> The rear axle final drive unit contains a Torsen type 1 Torque Sensing differential, instead of the more common hypoid open differential.<ref name=AudiV8.com_trans/><ref name=AudiStory.com/>
Engines
Both available engines used a Bosch Motronic<ref name=TopCarGuide3.6/><ref name=AudiV8.com/><ref name=TopCarGuide4.2>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> fully electronic engine control unit (ECU), with cylinder bank selective knock control,<ref name=AudiV8.com/> dual-barrel throttle valve, lambda mixture control via intake air volume metering and exhaust gas temperature sensor, and required unleaded petrol. Fuel was delivered to the combustion chambers via eight 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.<ref name=AudiV8.com/> The usage of 95 RON in the 4.2 V8 resulted in a lower power output, as well as increased fuel consumption.<ref name=AudiV8.com/>
At the initial launch of the Audi V8, the only offering was the 3.6-litre powerplant, which displaced Template:Convert.<ref name=Motor-Klassik/><ref name=TopCarGuide3.6/> This V8 engine was derived from the 1.8 16V engine from the Golf GTI.Template:Citation needed It was DIN-rated with a maximum motive power output of Template:Convert<ref name=ETKA/> at 5,800 revolutions per minute (rpm),<ref name=Motor-Klassik/> and generated a torque turning force of Template:Convert at 4,000 rpm.<ref name=TopCarGuide3.6/> In August 1991, Audi introduced a 4.2-litre engine, displacing Template:Convert,<ref name=TopCarGuide4.2/> 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.<ref name=ETKA/> 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.<ref>Image of 4.2 V8 Audi.

Transmissions
A choice of transmissions were offered.<ref name=ETKA/> A ZF Friedrichshafen-sourced four-speed 4HP24A automatic transmission with a torque converter was available throughout the V8 production run. Automatic transmission has three modes: "S" – Sport; "E" – Economic and "M" – Manual operation. St mode changes gears at higher rpms than E; M allows the driver to select gears using the lever.<ref name="Owners manual">Template:Cite book</ref> There were also two manual transmission offerings – for the 3.6: a five-speed manual gearbox, or later for the 4.2, a six-speed manual. Both manual transmission variants used a Template:Convert single-plate clutch.<ref name="Owners manual" />

Audi developed a Group A competition version of the Audi V8 for entry into the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) auto racing series equipped with a Template:Convert, later Template:Convert, 3.6 V8 engine and 6-speed manual transmission, and began racing with it in 1990 with Schmidt MotorSport (SMS) running the operation, and Hans-Joachim Stuck, Walter Röhrl and Frank Jelinski driving.<ref name="DTM90">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=Book3>Template:Cite book</ref> In the 1990 DTM season all of the three teams claimed together the entire podium (1st, 2nd and 3rd places) at Hockenheimring race.<ref>Template:Cite book</ref> Stuck won the title, and the following year, Audi added a second team to the mix, Audi Zentrum Reutlingen (AZR). SMS continued with Stuck and Jelinski, while AZR raced with Frank Biela and Hubert Haupt. Biela gave Audi another crown in 1991, but was unable to defend the title in 1992.<ref name="DTM91">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=Book3 /><ref name="audiworld.com">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
For the 1992 season, Audi had changed their engines to use a 180° flatplane crankshaft, which they said had been re-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.<ref name="audiworld.com" />
During its presence at DTM the Audi V8 competed with much smaller and about Template:Convert lighter Mercedes 190, BMW M3, and slightly smaller Opel Omega 3000. None of those cars were equipped with V8 engines or 4-wheel drive.<ref>{{#invoke:citation/CS1|citation |CitationClass=web
