The famous Italdesign Giugiaro presented at the Frankfurt auto show in 1973 the Audi Asso di Picche (which translates to ace of spades in Engish). The car was built by Karmann and it was the first of a series of three experimental coupe, designed for a possible production car.
The concept was based on the Audi 80 and it borrowed styling cues, such as the wedge body and sharp edges from the previous concepts of Giugiaro, which were the Maserati Boomerang and the Alfa Romeo Caimano. The quadruple round headlamps and horizontal rear lights were the only optical connections between the Asso di Picche and the first generation of the Audi 80.
Its interior featured a cylindrical structure which featured the air conditioning switches and various warning lights and it was used to replace the dashboard and the center console, while the leather pockets in the doors were shaped like handbags.
Karmann and Giugiaro hoped that Audi will send the model into limited production, which is why they had agreed to rely on a relatively unmodified chassis of an Audi 80, which ensured that the car could be equipped with either a 1.3-liter or a 1.5-liter four-cylinder engine. Both engines would send the power to the front wheels through a manual gearbox, without the company releasing any technical details.
Audi liked the Asso di Picche, but they did not add it to their range, because they preferred to focus their resources to create a full range of passenger cars before turning their attention to a limited production sport coupe model. Also Volkswagen feared that an Audi coupe will steal the spotlight from the Scirocco, which was scheduled to be launched next year.
