The Audi 100 C2 is a vehicle of the upper middle class of Audi NSU Auto Union AG which as a successor to the 1976 Audi 100 C1 was produced.

The newly developed vehicle (also known internally as the Type 43) was presented to the press in August 1976. With the new five-cylinder engines , this model clearly showed the influence of Audi's Chief Technology Officer Ferdinand Piëch . In addition to the first Avant models, which were presented in 1977, Audi presented the first five-cylinder diesel model in the C2. The powerful five-cylinder turbo models were presented at the 1979 IAA, but they were marketed as the Audi 200 .

After nearly 900,000 units were produced, the C2 was replaced in 1982 by the Audi 100 C3 with a new, more aerodynamic body.

Model history

General

Rear view

Compared to its predecessor, of which around 880,000 units were manufactured in around eight years, the Audi 100 C2 was completely redeveloped. The first Audi 100 C1 was often perceived as an “authorized signatory Mercedes ”, which was still located under the “dash-eight” Mercedes W 114/115. The new Audi 100 C2 now competed in the upper middle class against the Mercedes W 123 and the 5-series BMW .

Unlike its predecessor, which was initially designed for the European market, the new Audi 100 was to be a vehicle family that could be used around the world with a wide range of variations, as its developers outlined the development goal. Because meanwhile the potential of the US market had also become relevant for Audi. Essential elements of the platform architecture of the C2 should still exist in the C4 in 1990.

The model had a spacious body with a drag coefficient of 0.42 and a low curb weight for the vehicle class. Unlike its predecessor, no coupé was offered, but the hatchback "Audi 100 Avant " hatchback was later launched. A classic combination model was in development, but was ultimately not brought onto the market. Plans to bring the Avant model onto the market as a full-size VW were finally abandoned in 1975.

The previous model C1 was manufactured for the US market for a whole year until the summer of 1977 in Neckarsulm on the same line as the C2, because the US successor, the Audi 5000 , has not yet been homologated with the strict US emissions and safety legislation was completed.

design

The body shape was designed by Hartmut Warkuß , who was responsible for the design of numerous Audi and VW vehicles up until the 1990s. The so-called " Toronado line", which divides the side flank and makes the center of gravity appear optically deep, was a design element of the new Audi 100. Like the NSU Ro 80 , the four-door vehicles were given rear triangular windows that were typical of Audi design. The front and rear windows were glued into the body. The procedure was quite new at the time; One of the advantages is that the panes thus become elements that stabilize the body.

The interior was designed by Ro-80 designer Claus Luthe and the modern color palette in the 1970s in muted brown, blue, orange and green tones was developed in cooperation with the Munich architect Paolo Nestler . This was also responsible for the fact that no strong red was initially available ("Red creates avoidable aggression stimuli"). The basic idea was to shield the driver of the vehicle from bright color contrasts and to focus more on natural-looking colors. Not only were the upholstery fabrics color-coordinated, but also the interior trim, the dashboard, the floor carpets and even the steering wheel baffle plate .

Body styles

The four-door sedan first appeared in August 1976. The two-door version was also available from February 1977, but there was little demand for it. In September 1977 the Avant appeared with a hatchback and a large tailgate, but it is shorter than the sedan. Its rear end is similar to the VW Passat of the first and second series.

Technology and innovation

There have been advances in passive safety compared to its predecessor: With the principle of autogenous folding dents according to Tymoshenko , the front longitudinal members absorb impact energy.

With the exception of the EA-827 four-cylinder (63  kW / 85 PS) introduced in the Audi 80 in 1972, the larger vehicle than its predecessor was equipped with new engines. In addition to the larger EA-831 four-cylinder (85 kW / 115 PS), there was the first five-cylinder from Audi, the EA 828, from the beginning of 1977 . The Audi 100 5E caused quite a stir at its presentation and, with a displacement of 2.1 liters and mechanical gasoline injection Bosch K-Jetronic, developed 100 kW / 136 PS. For Japan this machine was equipped with a catalytic converter and throttled.

Daimler-Benz had already presented a five-cylinder diesel engine ( OM617 ) in the Mercedes 240 D 3.0 (W115) in 1974 . The engine was developed at the beginning of 1972 by Ferdinand Piëch , who for a short time ran his own engineering office in Stuttgart after leaving Porsche .

The basic idea behind the acoustically distinctive 2.1-liter five-cylinder engine was to create an engine that combines the smoothness of a six-cylinder with the economy of a four-cylinder.

In April 1978 the five-cylinder carburettor version Audi 100 5S with 85 kW (115 PS) replaced the equally powerful four-cylinder 2-liter EA 831 engine . The engine ( code letter WA) was also used in the VW LT and the AMC Gremlin .

In October 1978 the Audi 100 5D came on the market with a 51 kW (70 hp) 2-liter five-cylinder diesel engine based on the petrol engine. In the run-up to the presentation, a media-effective “world trip” was carried out. When crossing different continents around 30,000 km were covered to prove the reliability of Audi's first diesel model.

The lavishly equipped CD version was also released in 1978. This particularly comfortable equipment variant was only available in muted metallic tones, and electric window lifters, green tinted glass, light alloy wheels and power steering were standard. In the interior of the CD there were several cigarette lighters and two so-called "resting cushions" in the rear.

Wankel prototypes

The idea of offering the Audi 100 with a rotary engine , which would have given the NSU Ro 80 a successor in the Audi range, was discarded in 1977 after a comprehensive fleet test with the approximately 180 hp newly developed KKM 871 engine (rotary piston engine). The profitability of such a motorization was questionable.

Facelift

In August 1979 the Audi 100 was revised, which could be recognized by other headlights with white indicators, widened taillights and a revised interior.

At the end of 1979 the luxury variant Audi 200 C2 came onto the market. It was based on the Audi 100 CD and was available with a 100 kW (136 hp) injection engine ( Audi 200 5E ) and as a turbo version with 125 kW (170 hp) as the Audi 200 5T . The 200 was Audi's first foray into the luxury class.

A new 1.9-liter five-cylinder ( Audi 100 5 ) was available in August 1980 . The smallest five-cylinder in the program (100 hp) was manufactured in a total of only 11,635 units (615 of which were Avant). In Italy, this engine was also offered with the CD equipment otherwise not available in combination, because there is a luxury tax there for vehicles with a displacement of over 2.0 liters. In the summer of 1981 the versions CS (with front spoiler and light alloy wheels) and the energy-saving version Formula E appeared. The diesel engine could be ordered from November 1981 with exhaust gas turbocharger and 87 hp. The Audi 100 was also produced in small numbers at Volkswagen of Nigeria from supplied parts sets .

In August 1982, production of the C2 in Neckarsulm was stopped after 902,408 copies. Today these vehicles have become rare because of their susceptibility to rust.

According to the KBA, at least 1197 vehicles with the type code numbers of this series were registered as of January 1, 2015.

Its successor was the Audi 100 C3 .

US version

In the USA , the Audi 100 C2 was offered under the name Audi 5000 from 1978 to 1983 . In general, these models were better equipped, for example with leather seats and air conditioning, which were rarely installed in Europe.

In addition, the 5000 initially had round headlights. At the beginning of 1980 he too received the square headlights of the Audi 200 .

South Africa

At the end of 1977, CKD assembly of the Type 43 started at Volkswagen South-Africa (exclusively as a right-hand drive) in Uitenhage , South Africa. These vehicles differed from the models manufactured in Germany, partly due to the use of local supplier parts, but also different equipment logic and model names. They were replaced by the Audi 500 from the end of 1983.

Exterior paintwork

Exactly 44 paint finishes have been offered for the Audi 100 C2 over the years since its introduction in summer 1976. In addition to the standard uni paints, there were metallic paints as special equipment, as well as so-called extra-special colors (*). The range of colors offered was different in regional markets, so the range in continental Europe differed from that in the UK and USA. Schwarz Uni was always available in Great Britain, in continental Europe only from 1976 to 1978.
