The Audi Coupé was a liftback coupé version of the Audi 80, first shown in 1980. The bodywork was shared with the Audi Quattro. The second generation Coupé arrived in late 1988 and was based on the B3 Audi 80, albeit with a different suspension. The Coupé remained in production until the end of 1996 and spawned the Audi S2 series of sports versions. A convertible model arrived in 1991, called simply the Cabriolet, and remained in production until 2000.

The Audi Coupé (B2, Typ 81/85) was a two-door coupé produced and sold by Audi from 1980 to 1988. It was offered as a less expensive version of its turbocharged, permanent four-wheel drive Audi Quattro without turbocharger(s) 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.

Original Audi Coupé GT 5E, with the first style of headlamps

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 aspirated 1.9-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.

1983-1984 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 2309 cc "NG" five cylinder was available, offering 136 PS (100 kW) at 5600 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 5500 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) 2144 cc five-cylinder also used in the 5000 (Audi 100).

For the 1983 model year, European models switched from having two separate headlamps to large integrated Bosch units. Apart from changing the appearance, this also provided improved aerodynamics and better lighting.

Facelift

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.

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. Wheels 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 8,000 cars.

In October 1988, and after a brief hiatus for the Audi Coupé, a new three-door Coupé was introduced in Europe. This generation is known internally as the Typ 8B and is basically a Typ 89 saloon with a modified rear suspension and a new front suspension system which previewed what was to come in the B4 Audi 80. When introduced it was only available with either the ten- or twenty-valve 2.3E engine, which was later joined by the 115 PS (85 kW; 113 bhp) 2.0E and a number of other versions.

In February 1989 a 20-valve version of the 2.0-liter five-cylinder engine went on sale in Italy. This was the only version of the Coupé sold in Italy, where cars of over two liters suffer a high tax penalty. It was not offered anywhere besides Italy and Portugal as it was never fitted with a catalytic converter. The engine produces 160 PS (118 kW; 158 bhp) and this model was built until July 1991. Another export-market special built during the same period was an uncatalyzed, fuel injected 112 PS (82 kW) 1.8-liter inline-four. A naturally aspirated, 136 PS (100 kW; 134 hp) 2.2E was also sold in some markets until late 1991, including the United Kingdom and Spain. In September 1990 the sporty S2 Coupé was introduced, followed one year later by a more luxury-oriented 2.8-liter V6 version. The Coupé received similar updates to the B4 Audi 80 and remained in production until December 1996. The Coupé did not have a direct replacement but was effectively succeeded by the first-generation Audi TT coupé (and roadster), sold between 1998 and 2006.

S2 Coupé

Together with Konrad Schmidt Motorsport GmbH (SMS), who had been responsible for Audi's DTM version of the V8 quattro, Audi developed a sports version of the Coupé in September 1990 called the Audi S2. This was meant to boost lagging sales of the Coupé and replace the famous Audi Quattro (launched in 1980). It featured the well-proven 2.2-litre in-line five-cylinder 20-valve turbo petrol engine from the Audi 200 20V, which was a variant of the engine used in the Audi Quattro. A similar version of the engine was used in the Audi 100 based S4 (the 'Ur-S4'). The S2 came as standard with quattro permanent four-wheel drive, and featured a heavy-duty 5-speed manual transmission, and was capable of 150 mph.

The S2 was initially available with a 2.2-litre turbocharged engine which produced 220 PS (162 kW; 217 bhp) (Engine code 3B), coupled to a 5-speed transmission. In 1992, the engine received minor upgrades, including distributor-less ignition, which increased power output to 230 PS (169 kW; 227 bhp) (Engine code: ABY) which was coupled to a new 6-speed gearbox. Although the power increase was minimal, the engine now produced 350 N⋅m (258 lb⋅ft) of torque (up from 309 N⋅m (228 lb⋅ft)) and featured an overboost function that allowed up to 380 N⋅m (280 lb⋅ft) in short bursts. The 3B-engined car will accelerate from 0-100 km/h (62.1 mph) in 5.7 seconds, continuing to a top speed of 246 km/h (152.9 mph). The ABY-engined S2 Coupé will accelerate from 0-100 km/h (62.1 mph) in 5.9 seconds, continuing to a top speed of 246 km/h (152.9 mph).

In 1993, the S2 received some cosmetic updates, including new AVUS-style alloy wheels, ellipsoid beam (projector) headlamps and clear front indicator lenses.

North America

In 1989, for the 1990 model year, North America received the Coupé quattro. It was powered by a detuned 164 hp (122 kW; 166 PS) version of the 20-valve 2.3-litre five-cylinder engine and was originally only available with a five-speed manual transmission. It was marketed in the "Grand Tourismo" (GT) style of a comfortable luxury car with sporting tendencies, as opposed to a dedicated lightweight sports car. Weighing 3,308 lb (1,500 kg) (1991 Coupé model) it was not a lightweight, especially in consideration of the 164 hp powerplant (slightly less than the European version). These models came standard with 15" 6-star "Speedline" wheels, leather interiors with Zebrano wood trim, additional VDO gauges mounted in the bottom of the centre console, a carbon fibre centre prop shaft, and push-button locking rear differential. The Coupé quattro is visually similar to the European-only S2 model, but does not have the S2's turbocharged engine. It was only sold for two model years in the United States, 1990 and 1991.

The Audi Cabriolet (Typ 8G) based on the B3 Coupé, was introduced in May 1991. As a result of the heavy and expensive re-engineering involved in creating a cabriolet version, this model was produced up until the year 2000; long after the other B3 models had been replaced by B4 and even B5 vehicles. It was the company's first soft-top since the Auto Union 1000 Sp of 1959. The Cabriolet featured the updated bonnet and rear light design among other styling features from the B3-based S2 Coupé. Initially only available with the 10-valve 2.3-litre inline-five, the 2.8-litre V6 was added for the US market, and the 2.0-litre inline-four and 2.6-litre V6 from the Coupé were added as options in 1993 in Europe. The 2.0-litre was later replaced in 1997 by the new 20-valve 1.8-litre inline-four from the new A4. The Cabriolet was heavily engineered to retain the structural strength of the Coupé (with which it shared its suspension layout), and its windscreen was reinforced to preclude the need for a roll bar. The Cabriolet was never offered with the quattro four-wheel drive system. Final assembly was by Karmann in Osnabrück from 1997.

In April 1997 the European market Cabriolet underwent a few minor yet visible touch-ups; such as gently redesigned bumpers incorporating lights from the Porsche 911 (993), projection lens headlamps, as well as other minor changes. In addition to this facelift, a special edition was introduced for the European market under the name Sunline. Among other extras, it was equipped with all leather interior, air conditioning, 16-inch alloy wheels, a power soft-top and a leather steering wheel. A 'Final Edition' with similar extras became available from 1999 until the end of production.

In November 1993, the 2.8-liter V6 equipped Cabriolet entered the US market, where it remained on sale until the end of the 1998 model year. Altogether, 5,445 were sold there over 5 years.

A 4-seater mid-sized Audi convertible was not available again until 2002, when the B6-based A4 Cabriolet (Typ 8H) was introduced.

Overall, a total of around 71,350 Cabriolets were built.
