Stunning, Classic Audis on Display in Mobile Show

Running from May 3 to September 18, the Audi ‘museum mobile’ is presenting 12 coupés from the 1930s to the present day, in an exhibition titled “Dynamic Sculpture – the Tradition of Sportiness and Elegance at Audi.”

When vehicles with the coupé body type first appeared on the scene, they were often known as “Les Désobligeantes” (the unobliging ones). The style takes its name from the idea to “cut” (“couper/coupé” in French) a four-seater coach body to create a two-seater. The result was a body type that aroused the interest of the elite set. And in the years that followed, the high-quality interior equipment and trim installed in coupes made them the favorite vehicles among the high society of major European cities.

With the initial attempts at streamlined design in the 1930s, the roof form sloping downward to the rear began to catch on. The criteria by which we define a coupé today emerged only gradually, however: a short, flattened roof resting on two posts, with a two-seat interior. The coupes really hit their stride in the 1950s and 1960s. A key factor behind this popularity was the long-distance races of the period, like the Mille Miglia, the Targa Florio, the Liège-Rome-Liège race and the “2000 km durch Deutschland” (2,000 kilometers though Germany), which almost seemed to have been conceived specifically for coupes. Typical of coupe design was the combination of a great looking exterior and the best technology. Still today, the coupe is seen as the jewel in the product lineup of every automaker.

At the show will be 12 coupés from Audi history. A particular highlight is a replica of the “Manuela,” a unique coupé version of the Horch 853. The car was specially built for Bernd Rosemeyer in 1937. The most successful and most popular Grand Prix driver for Auto Union back then, Rosemeyer loved this luxury automobile – a passion clearly captured in countless photographs. This and the fact that the motorsport star was killed while attempting a world record run just a few months after he got the car, exalted the Horch “Manuela” to its legendary status. It is believed the original coupe disappeared without a trace during World War II.

Other treasures from the annals of company history trace the body type through the 1950s: a rare DKW Meisterklasse Coupé with a body by the specialist company Hebmüller, a DKW Monza (1956), the Auto Union 1000 Sp (1958) and an NSU Sport Prinz (1959). Also included in the exhibition is the first Audi coupe of the post-war era, the Audi 100 Coupé S from 1970. Representing the historic return of the four rings to the premium segment are the Audi Coupé GT (1980), the Audi quattro (1981), the Audi Sport quattro (1983) and the Audi Coupé from 1988. Visitors will also have the opportunity to see the first edition of the style icon Audi TT from its debut year 1998. And finally, the path to the present culminates with the Audi A5 from 2007.

Proton Exchange Membrane Fuel Cell

The Proton Exchange Membrane fuel cell, sometimes referred to as the Polymer Electrolyte Membrane fuel cell, is the chosen form for use in automotive applications.

Key   A. Hydrogen flow field

B. Oxygen flow field

C. Hydrogen

D. Oxygen (in air)

E. Backing layers

F. Anode

G. PEM (the electrolyte)

H. Cathode

J. Unused Hydrogen

K. Water

Process Hydrogen is passed through field flow plates to the anode whilst oxygen is similarly directed to the cathode. A platinum catalyst at the anode splits the hydrogen into protons (hydrogen ions) and negatively charged electrons. The electolyte (PEM) only allows the protons to pass through it directly to the cathode. The negatively charged electrons are forced to travel via a separate circuit to the cathode – hence generating an electrical current.

The energy from a single fuel cell is relatively small which means that multiple fuel cells must be used together before it is practical to power a vehicle. Fuel cells placed together are known as a ‘stack’.      

Passenger Safety

  Passenger safety (including drivers) in vehicles is by far the most considered field of automotive safety. Although the focus is only now falling on pedestrian safety, passenger safety has been at the top of the agenda since the World’s various automotive regulatory bodies were founded. The result of decades of concentrated effort is a good public understanding of simple concepts such as crash cages and crumple zones whilst the industry has developed specialists in almost all related technical areas. In this section, we look at the key safety considerations when designing a vehicle, as well as more technical aspects affecting systems and components.

Automotive Design

Welcome to the design section of Car Design Online. This area includes information on most of the pre-production elements of automotive design. These include the creative elements of vehicle development, such as sketching and modelling, as well as other important considerations, namely aerodynamics and ergonomics.


In this section we take a look at the science of aerodynamics and how manufacturers use CAD and wind-tunnel testing to perfect new vehicles.


An increasingly important aspect of automotive design, this section on ergonomics and anthropometrics looks at design for human form and behaviour.


Whether virtual or actual, realising a design in 3D has always been a critical element of vehicle development. From clay to CAD, we look at the different methods and practices.


From a designer’s initial idea to fully resolved renderings; we take a look at how ideas are realised in 2D.
