Audi is taking an outstanding display of its cars to the world's largest classic car show, the Techno Classica, which is held in the German city of Essen. To commemorate the centenary of the brand, Audi Tradition will have exclusively Audi models on its stand in Hall 7 from April 5, 2009 onwards. The absolute highlight, reconstruction of which has just been completed, is the 1935 Audi 225 Front Roadster. It is on loan for the occasion from the recently opened special exhibition "Horch – an Audi!" at the museum mobile in Ingolstadt.

The Audi stand is displaying seven cars covering no fewer than nine decades of the company's history. From the Audi Type C "Alpine Champion" of 1919 to the Audi R10 TDI that won the Le Mans 24-hour race in 2008, each of them, whether production model, racing car or prototype, contributes an exciting story of its own to the Audi centenary celebrations.

As before, Audi Tradition will be displaying its 1:43 scale "model of the year" on the stand: an Audi Sport quattro S1 Pikes Peak with orange paintwork, of which a limited edition of only 333 has been produced. And from 11 a.m. to 12 noon on Saturday April 4, the authors of the "Edition Audi Tradition" books published by Delius Klasing will be on the stand to sign copies.

Visitors to the Essen show can look forward to seeing the following Audi vehicles: the oldest is the Type C "Alpine Champion" with which company founder August Horch won the Austrian Alpine Rally in 1912, 1913 and 1914 – the Audi brand's first motor-sport successes. The Type C was an open tourer with a 35-horsepower engine and a top speed of 80 km/h. Possibly an even greater eye-catcher on the Audi stand is another highlight in the brand's history: the Audi 225 Front Roadster dating from 1935. Reconstructed on an original chassis frame, this new addition to Audi Tradition's historic collection is also one of its most spectacular cars. It was first exhibited with a gleaming white paint finish at the 1935 International Motor Show in Berlin. Only two prototypes were built; although the car created a sensation and was greatly admired, it would have been too expensive for successful series production. Both prototypes have disappeared, and it was therefore decided to build a replica of the Audi 225 Front Roadster by working from photographs.

The Audi 72 played an important role in the brand's history. Introduced on August 13, 1965 as the Auto Union's first post-war car with a four-stroke engine, it ushered in a new era for the Ingolstadt-based manufacturer and the abandonment of the two-stroke engine. Between 1965 and 1968 85,000 units of this model, which revived the distinguished Audi name, were sold. A further step back into the premium car class was taken in 1982, when the third-generation (C3) Audi 100 set new standards for aerodynamic efficiency and in many other areas too. The C3 pioneered new design principles and had the outstandingly low drag coefficient of cD = 0.30 – a new world record for a series-production saloon car.

AUDI AG had a high reputation for concept cars to maintain. At the 1991 International Motor Show in Frankfurt, the Audi quattro Spyder caused a sensation. It was the most dramatic sports car concept study so far seen from Audi. Powered by a 174 bhp four-stroke engine and with an aluminium body, it could reach a top speed of 250 km/h, but was destined to remain a prototype although Audi dealers received hundreds of purchase options from intending customers. It proved impossible to put the car into production without exceeding the target price of 100,000 Deutschmarks.

Audi Tradition is illustrating the company's position in motor sport at the 2009 Techno Classica in a truly impressive way by displaying the Audi Sport quattro S1 "Pikes Peak" and the Audi R10 TDI. For motor sport fans, the Audi Sport quattro S1 "Pikes Peak" has long since achieved the status of a legend. Also nicknamed "The Monster", the S1 triumphed three times in succession at this hillclimb, held on the slopes of a 4,301 metre high mountain in Colorado, USA. Few people will ever forget the way that Walter Röhrl stormed to the top in under eleven minutes, the first driver to achieve this sensational time. This was the last of a series of successes for the Audi Sport quattro S1, since Audi had withdrawn from rallying two years earlier.

The Audi R10 TDI is the first sports car to have won the Le Mans 24-hour race with diesel fuel in its tank – and has now pulled off this feat three times in succession. The breathtaking finish in 2008 will not be forgotten: the Audi R10 TDI, which scored its first victory in this event in 2006, fought off the challenge from Peugeot's faster, more recently developed car. Motor sport fans will be able to see the 2006 version of the Audi R10 TDI at the Techno Classica in Essen.
