Squille innovation: Audi Type C Jaray in the August Horch Museum!

In the August Horch Museum in Zwickau, a very special piece of automotive history is now presented. From now on, a foam model of the Audi type C Jaray from 1923 is adorned with the permanent exhibition, which impressively documents the beginnings of aerodynamics. As reported [Radio Zwickau] (https://www.radiozwickau.de/biebtrag/horchmuseum-dioTen- an--er-aerodynamics-869793/), this model was developed for the special exhibition "Wind cutting" in cooperation with the West Saxon University and shows the key concepts that still shape aerodynamics.

The Audi Type C Jaray is equipped with a 4-cylinder engine that offers a displacement of 3,564 cm³ and reaches 35 hp at 1,700 rpm. The speed of 130 km/h is remarkable, which stands out significantly from the 90 km/h of the series models. The CW value, a measure of air resistance, is estimated at 0.3 to 0.36.

pioneers of aerodynamics

Already at the beginning of the 20th century, engineers such as Paul Jaray, Edmund Rumpler and Freiherr Reinhard von Koenig-Fachsenfeld dealt with the adaptation of the body forms to the air flow. The first considerations on aerodynamics initially had the goal of reducing the arsulator of street dirt. Doch schon bald wurde klar, dass eine bessere Strömungsgestaltung auch die Geschwindigkeit und den Kraftstoffverbrauch positiv beeinflussen kann, wie KFZ-Betrieb determined.

The exhibition "Smart" in the Audi Museum Mobile will illuminate the development of aerodynamics until 1945 and offers over a dozen impressive exhibits. One of the highlights is the model of the Audi Type C Jaray, which shows how the design of the vehicles in the context of efficiency, sustainability and design has been developed.

Review and outlook

The methods of wind tunnel research have contributed significantly to the acceptance of aerodynamic designs. While the development after the Second World War temporarily lost importance, aerodynamics in the 1970s experienced a comeback due to the oil crisis. Vehicle manufacturers such as BMW, Mercedes-Benz and VW invested in their own wind tunnel centers to minimize the air resistance of their vehicles. In the GDR, research was also intensively researched, but economic difficulties often resulted in implementation of the knowledge.

In 1982, Audi presented the Audi 100, which with a CW value of 0.31 is considered one of the most aerodynamic cars of its time. Historical milestones such as the Citroën DS or the Porsche 356 are further examples of how important the aerodynamics in automotive history were always, so Auto Bild.

From December 1, 2023, the August Horch Museum follows with the exhibition "Form Completed" on the occasion of the aerodynamic innovations of the post -war period. Visitors can look forward to over 20 grand exponats and interactive displays that document the development by June 30, 2024.

The current transformation to electromobility once again emphasizes the importance of aerodynamics, because the reduction of air resistance is crucial for range and efficiency. In this way, the history of aerodynamics remains exciting and relevant for the future of the automotive.
