Audi V8

The Audi V8 ( Typ 4C ) is a four-door, full-size. luxury sedan. built by Audi in Germany from 1988 to 1993, as the company’s flagship model. It was the first car from Audi to use a V8 engine. and also 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 sold in North America until 1997.

Overview [ edit ]

The Audi V8 had a galvanized steel body, with a 10-year anti-perforation warranty (against corrosion). [ 7 ] 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 [ 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. [ 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 [ edit ]

The styling of the Audi V8 resembled the Typ 44 Audi 100 and 200 models, [ 3 ] [ 12 ] and was based on a stretched version of the Volkswagen Group C3 automobile platform. known either as the D1 or D11 [ 9 ] [ 12 ] 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, extended wheelbase. wider track, pronounced fenders. and a completely different 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 ]

A one-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 Ingolstad. The car is now in storage in Neckarsulm. [ 12 ] [ 14 ]

Powertrain [ edit ]

Powertrain [ 3 ] 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). [ 15 ] 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 lead to easier and less costly maintenance of the timing belt and associated components. The intervals for changing the timing belts varied; the 3.6#160;V8 (PT ) required changing every 90,000 kilometres (60,000#160;mi), [ 15 ] whereas the 4.2#160;V8 (ABH ) had a longer interval at 120,000 kilometres (75,000#160;mi). [ 15 ] 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. [ 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 ]
