F103 is the internal designation for a series of car models produced by Auto Union in West Germany from 1965 to 1972, derived from the earlier DKW F102. To signify the change from a two-stroke to four-stroke engine, the DKW marque was dropped in favour of Audi, a name dormant since before the Second World War.

Models

The first model was launched simply as the Audi, later being renamed the Audi 72 (72 being the nominal power output of the engine in Pferdestärke).

The more powerful Audi 80 and Audi Super 90 sports saloons appeared in 1966: in 1968 the arrival of the less powerful Audi 60 completed the range.

The Audi 75 replaced both the Audi 72 and the Audi 80 from 1969 onwards.

In 1972 the F103 series was discontinued in favour of the "B1" Audi 80.

Engines

The F103 series were equipped exclusively with four-cylinder four-stroke engines. These were longitudinally mounted. This combination of front-wheel drive, which Auto Union'sDKW brand had pioneered during the 1930s, and the longitudinally positioning of a four-cylinder engine would provide the basic template for Volkswagen's successful new Passat as well as the Audi models Audi 80 and Audi 100 after Volkswagen acquired the businessfrom Daimler-Benz late in 1964. Since the chassis on the F103 was taken from the DKW F102 with a 3-cylinder two-stroke engine the longer engine meant that the cooling system had to be offset to the left of the engine instead of the normal position in front of it.

The engines of the F103 series were a joint development with Daimler-Benz who owned Auto-Union at the time (from 1958 to 1964). They were dubbed the Mitteldruckmotor (medium pressure engines), because of their unusually high compression ratio, mid-way between conventional petrol and diesel engines.

Running gear

The car came with a four-speed manual transmission.

Inboard mounted front disc brakes were featured, which was still unusual in the mid-size car market at this time. The rear brakes followed the more conventional drum configuration.

Bodywork

The form of the Audi F103's body closely followed that of the earlier DKW F102, shown here, though the Audi's engine represented a dramatic break with the two-stroke DKW tradition.

The F103 bodyshell was a development of the earlier DKW F102. The engine compartment had to be extended so that the new four-cylinder engine could be accommodated. The front and tail were also cosmetically revised: Audi F103s sold in Europe all featured quasi-rectangular headlamps which were becoming fashionable at the time, whereas the F102 had used round headlamp units.

All Audi F103 models were offered as sedans with two and four doors. However, the two-door saloon/sedan was not sold in markets with little demand for two-door cars of this size, such as Italy and Britain.

With the exception of the Audi Super 90, the F103 series were available also as three-door station wagon models. Making its debut at the Geneva Motor Show in March 1966, this was called, like the Volkswagen estate/station wagon models, Variant.

Commercial

During the early 1960s Auto Union was in commercial retreat: the Audi F103 was a relative success when compared with recent Auto Union products even if its commercial success was trumped by subsequent Audi models. In July 1967 it was reported that 100,000 Audis had been completed: production of the F103 had by now built up to a rate of almost 40,000 per year and the company was moved to deny speculation that another new Audi model would be presented at the Frankfurt Motor Show in the Autumn / Fall of 1967. (The Audi 100 was introduced only towards the end of 1968.)

The Audi Coupé (B2, Typ 81/85) is a two-door coupé produced and sold by Audi from 1980 to 1988. The car was an attempt by Audi to offer a cheaper version of itsturbocharged, permanent four-wheel drive Audi Quattro - without turbochargers or four wheel drive. Later, quattro was added as an option (Typ 85). Typ 81 was the internal model code for front-wheel drive Audi Coupés.

The Coupé, first displayed at the Paris Salon 1980, featured a similar body shape to the Quattro, but without the knife-edged fender flares of the more expensive car. Mechanically, the biggest changes from the Quattro to the Coupé were the use of a naturally aspirated1.9 litre carburettor petrol engine, 2.0 litre, 2.1, 2.2, or 2.3 litre fuel injected inline five cylinder engine and a front-wheel drive drivetrain. Some lesser Coupés were also fitted with a 1.8 litre inline four cylinder engine, injected or carburetted, and for the very first year of production a 1.6-litre "YN" 75 PS (55 kW) engine was available. The short-lived 1.6 was the only Coupé not to be fitted with a black rear spoiler.

History

Early Coupé GL - note body coloured B-pillar and 13-inch steel wheels

The Coupé was available as just plain "Coupé" or GL (four-cylinders only), "Coupé GT", and "Coupé quattro" (without the GT tag). From 1986 until the end of production in late 1988, the Coupé GT was also available with the 110–112 PS (81–82 kW) 1.8-litre PV/DZ inline-four best known from the Golf GTi.For the last model year, the new 2,309 cc "NG" five cylinder was available, offering 136 PS (100 kW) at 5,600 rpm. This engine became available during 1987 for the last of the Audi Coupés sold in the US, where it produced 130 hp (97 kW) at 5,700 rpm as opposed to the 110 hp (82 kW) at 5,500 rpm available from the 2.2-litre five which had been used since the facelift for model year 1985. The Coupé had originally gone on sale in the US late in model year 1981 with the 100 hp (75 kW) 2,144 cc five-cylinder also used in the 5000 (Audi 100).

Facelift

Facelifted Coupé GT

The updated Coupé, introduced after the German industrial holidays in the autumn of 1984, was given new, slightly sloped radiator grille and headlights, a large wrap-around bumper with integrated spotlights and turn signals, plastic sill covers, and the large rear spoiler from the Audi Quattro. These changes brought the drag coefficient down to 0.36. A new dashboard was also introduced, as was a new interior. GL and standard versions were cancelled for model year 1987 and all FWD Coupés were from then referred to as "Coupé GT".

For the 1986 model year, the Coupés (as with all Audis) were available with more catalyzed engine options. Also, the entire B2 range (Audi 80/90/Coupé) received stainless steel exhausts (for European markets at least).

Coupé quattro

Also in September 1984, Audi made available the option of the quattro permanent four-wheel drive system to produce the Audi Coupé quattro, a model which was rarer than the turbocharged Quattro model. While most common with the 2.2 litre engine (also 2.3 for the last year, introduced 1987 for the US), in some markets the 1.8 litre four-cylinder models (90 and 112 PS DS/NE/JN or DZ engines) were also available with four-wheel drive.

The Coupé and Coupé quattro models appear almost identical from the outside except for a few minor "quattro" specifics. While the GT had "COUPE GT" on the rear side windows, the CQ had the "quattro" decal as used on the Ur-Quattro. Similarly at the rear, the badging was "GT" and "quattro" respectively. The quattro versions also used the Ur-Quattro rear windscreen with "quattro" written into the heater elements (very obviously so on a cold and frosty morning), and the front grille was also adorned with the "quattro" badge from the Ur-Q. Inside, the cabin was identical except that the centre console received a differential lock switch, and LED bargraph displays in place of the GT's three analogue-style gauges. Some Coupé quattros were distinguished by a body-coloured rear spoiler.

Rear view of facelift Coupé GT

Mechanically, the Coupé quattro depended on a combination of components from the GT and the Audi 80 quattro. The quattro permanent four-wheel drive drivetrain was almost identical to that used on the Ur-Quattro - the main differences being the use of the Coupé GT front struts, smaller 256 mm (10 in) diameter front brake disks, and lower ratios in the gearbox and rear differential. The damper and spring rates were also different from the Ur-Q. It was thus largely identical to the Audi 90 quattro and the North American Audi 4000 quattro. Roadwheels were 6.0Jx14", with steel or aluminium alloy rims dependent on the market. 7.0Jx15" Ronals, almost identical to the Ur-Quattro wheels, were also available. The CQ/90Q/4000Q also received their own exhaust manifold and downpipe (5-3-1, while FWD versions were 5-2-1).

From September 1980 to September 1987, 174,687 Typ 81 Coupés were built. Quattro production ran from late 1984 to 1988, and was in the total region of 8000 cars.
