Audi 100 Coupe S
The Audi 100 Coupe S was a pivotal car for Audi. In the late 1960s, Audi was a relatively obscure brand, recently revived from the ashes of Auto Union by Volkswagen. The 100 sedan, launched in 1968, was Audi's first independently developed car under VW ownership and a crucial step in establishing the brand's identity. The Coupe S, launched in 1970, added a sporting dimension that the sedan lacked.
Designed by Hartmut Warkuss (who would later design the original Audi TT), the 100 Coupe S featured elegant fastback styling that was remarkably clean and modern for its era. The long hood, short rear deck, and sweeping roofline created a profile that looked far more expensive than its price tag suggested. The pillarless side glass treatment gave the greenhouse an airy, sophisticated character.
Under the elegant skin, the Coupe S used an uprated version of the 100's 1.9-liter four-cylinder engine, producing 112 hp DIN — enough to push the lightweight coupe to 185 km/h. Front-wheel drive was unusual for a sporting coupe in 1970, but Audi's engineering made it work surprisingly well, with predictable handling and good front-end grip.
The interior was nicely appointed for its class, with comfortable seats, clear instrumentation, and a quality feel that hinted at Audi's future positioning as a premium brand. The hatchback-style rear opening provided practical luggage access, making the Coupe S a genuine grand touring car rather than a mere style exercise.
Approximately 30,687 Coupe S models were built during its six-year production run — a modest number that reflects the car's niche appeal. The Coupe S was not a mass-market car; it was aimed at buyers who wanted something more distinctive and sporting than a standard sedan but didn't want the flashiness of an Italian design.
Today, the Audi 100 Coupe S is an underappreciated classic. Survivors are uncommon, and good examples are increasingly valued by collectors who recognize the car's historical importance as a key step in Audi's evolution from a forgotten brand to a global luxury powerhouse. The clean design has aged beautifully, and the driving experience remains engaging.
Survivors are rare, making finding one the primary challenge. Rust is the main enemy — check floor pans, sills, wheel arches, and the complex rear fender area. The four-cylinder engine is robust but finding specific parts can be difficult. The front-wheel-drive layout means the gearbox and CV joints should be inspected carefully. Interior trim parts are scarce. The electrical system is simple and generally reliable. Verify the car is a genuine Coupe S (not a sedan conversion). Documentation and matching numbers add significant value given the rarity.
30,687 units produced (1970-1976). The Coupe S used the same platform as the 100 sedan but with unique bodywork from the B-pillar back. Available with both manual and automatic transmissions. Some markets received a de-tuned version with the standard 100 LS engine. The Coupe S was not officially sold in the US market.
