Audi 100

Hello, i'm talking now about Audi 100.

Audi 100 are mid-sized executive cars manufactured in 1986-1994.

Audi 100 C1:

The Audi 100 was shown to the press on 26 November 1968. Its name originally denoting a power output of 100 PS (74 kW; 99 hp), the Audi 100 was the company's largest car since the revival of the Audi brand by Volkswagen in 1965. The C1 platform spawned several variants: the Audi 100 two- and four-door saloons, and the Audi 100 Coupé S, a stylish fastback coupé, which bore a remarkable resemblance to the Aston Martin DBS released a year earlier, especially at the rear end, including details such as the louvres behind the rear side windows and shape of the rear light clusters.

Audi followed up the introduction of the four-door saloon in November 1968 with a two-door saloon in October 1969 and the 100 Coupé S in autumn 1970. The cars' four-cylinder engines originally came in base 100 ( 80 PS or 59 kW; 79 hp), 100 S (1.8 litre, 90 PS or 66 kW; 89 hp) and 100 LS (1.8 litre, 100 PS or 74 kW; 99 hp) guise, while the Coupé was driven by a bored-out 1.9 litre developing 115 PS (85 kW; 113 hp). From April 1970 the 100 LS could be ordered with a three-speed automatic transmission sourced from Volkswagen.

The Audi 100 enjoyed a level of commercial success for which the company had not planned. As a distinguished German commentator pointed out, the rough engine note was unlikely to discourage buyers whose first car had been a Volkswagen and who aspired to drive a diesel powered (pre-turbo) Mercedes-Benz. Despite running the Ingolstadt production line at full capacity, supply fell short of demand to such an extent that during the summer of 1970 an additional production line for Audi 100s was set up in Volkswagen's own Wolfsburg plant, which made it the first water-cooled car to be produced in Germany's (and by some criteria the world's) largest car plant.

Starting with model year 1972 the 80 and 90 PS versions were replaced by a new regular-petrol-variant of the 1.8 litre engine developing 85 PS (84 hp/63 kW); at the same time, the 100 GL was introduced that featured the 1.9 liter engine formerly used in the Coupé S only.

In March 1971 the 500,000th Audi was produced. By now the Audi 100 had become the most commercially successful model in the company's history, so it is unsurprising that the car in question was an Audi 100 produced at the Ingolstadt plant.

In September 1973 the 100 received a minor facelift with a somewhat smaller grille and reshuffled taillight lens patterns. The rear torsion bar was replaced by coil springs. For model year 1975 the base 100 was re-christened the 100 L and received a 1.6 litre four-cylinder engine (coming out of the Audi 80). A four-wheel drive prototype of the Audi 100 C1 was built in 1976, long before the appearance of the quattro.

In the United States the Audi 100 appeared in 1970 in LS guise, with a 115 hp (86 kW) SAE 1.8 liter engine and with either two or four doors. For 1972 the engine was enlarged to 1.9 litres, but since the power figures were now in SAE net claimed power was down to a less impressive sounding 91 hp (68 kW). A base and a GL model were added, as was an automatic transmission. For 1974 the lineup was again restricted to the 100 LS, while the larger safety bumpers were now fitted. Power increased to 95 hp (71 kW) for 1975, courtesy of fuel injection. Standard equipment was also improved, but at the cost of a sizable price hike. In August 1977 the new Audi 5000 replaced the 100, although another 537 leftover cars were sold in 1978. The Coupé was never sold in the United States.

Audi 100 C2:

The restyled C2 Audi 100 was launched in 1976, with an in-line five-cylinder engine. It was initially a 100 PS (74 kW) engine offering "six-cylinder power and four-cylinder economy", and later upgraded to 136 PS (100 kW).

The Coupé was discontinued, but a five-door hatchback model, the 100 Avant, was launched in August 1977 as part of this generation. The mainstay of the range remained the four-door sedan model. A two-door sedan version was offered, primarily on the domestic market, from February 1977, but by now there was little demand, even in Germany, for large two-door sedans: few of these two-door Audi 100 C2s were sold.

At the end of September 1977, the Audi 100 became the manufacturer's first model to reach a production level of 1,000,000 units. The millionth Audi 100 was a hatchback Audi 100 Avant assembled not at the company's main Ingolstadt plant but to the west, at the Neckarsulm factory which, since the demise of the mainstream volume models from the NSU range, had been concentrating on providing additional production capacity for the fast selling Audi range.

Audi 100 C2 had differrent nad new engines.

Audi 100 C3:

Edging out the Ford Sierra as the 1983 European Car of the Year, the 1983 Audi 100 had a remarkably aerodynamic look, achieving a drag coefficient of 0.30 for its smoothest base model. The increased aerodynamic efficiency resulted in better fuel economy and consumers all over the world were waking up to this fact. This became a great marketing tool for Audi in the 1980s, and marked a huge leap forward from the boxy shape of the C2, as well as the technology it introduced, including the procon-ten safety system.

Audi was able to follow up on the modern smooth look first seen in this segment on the 1967 NSU Ro 80 and popularised by the 1974 Citroën CX. This rounded look became the norm by the 1990s. It also set a styling trend of flush wheel covers, a thick black side door moulding and blacked out window frames eventually adopted by a range of cars such as the 1984 Honda Accord and the Chrysler K cars. Audi innovated flush windows on the C3, a key area for aerodynamic drag that has been adopted by virtually all manufacturers today. In addition to giving it better fuel economy its aerodynamic body gave the 100 higher top speed than other cars of similar engine size.

The two-door models were no longer available, and the Audi 100 Avant was reintroduced as Audi's first attempt at a station wagon based on the 100. The 200, launched in 1983 continued as the upmarket variant with several versions of the 2.2 L turbo 5-cylinder available in different markets over its life ranging in power outputs from 165 PS (121 kW) MC engine, through the 200 PS (147 kW) versions to the final 220 PS (162 kW) 20-valve 3B engine available from 1991. Due to its low drag coefficient, the 1983 Audi 200 Turbo had a top speed of 139 mph (224 km/h). The MC turbo engine was available in the 100 as well for some markets.

The 1991 200 20V was distinguished by its flared front and rounded rear wheel arches instead of the flat type used for the rest of the 100-200 range, this allowed wider wheel and tire combinations to be fitted to 20V models. For many markets, the 20V Audi 200 gave customers a taste of performance levels that would later be seen in the C4-Chassis Audi S4, and S6. US Magazine articles of the period reported 0-60 times of the 20v Audi 200 under 7 seconds, with 1/4 mile times in the mid to upper 15 second mark.

The 100 also featured a 2.5 L straight-five direct injection turbo-diesel (TDI) model with 120 PS (88 kW) introduced in January 1990 (engine code 1T). A such-engined Audi 100 was the very first model to wear the now ubiquitous and hugely successful TDI label that changed the perception of diesel engines all over the world. It had a brief career in the C3, being replaced in December of that year when the C4 arrived.

Audi 100 C4:

Audi released the C4 (a heavily revised C3) in 1991. The C3-platform Audi V8 continued to be sold as a separate line. The major change for the C4 was the introduction of a 2.8 L, 90-degree, SOHC 12v, V6 engine. It was later joined by a 2.6 L variant, of the same configuration as the 2.8 L unit. They are essentially the same engines offered in the 1992, B4 Audi 80. The option of quattro permanent four-wheel drive was an option across the range, and the Audi 100 quattro was available with a ZF four-speed automatic gearbox.

For the 1995 model year, in conjunction with some styling revisions, Audi dropped the Audi 100 tag, renaming it the A6 instead. In addition, the existing 100-derived Audi S4 became the S6. The S4 name was later re-used for the high-performance derivative of the Audi A4. The Audi V8 had been replaced by the A8 in 1994.

The C4-based A6 continued until early 1997, when it was replaced by an all-new A6.

In 1994 Audi 100 C4 was replaced by Audi A6 C4, but it was allmost the same.
