Booklet features a selection of more than two dozen anniversaries The launch of the Audi A2 25 years ago; the first new Audi in post-war times 60 years ago; and Hans Stuck’s record-breaking exploits in the “world’s fastest road-going car” near Lucca 90 years ago With the “Anniversary Dates 2025” booklet, Audi Tradition is showcasing the most important moments in the product and company history of Audi, which is as eventful as it is diverse. Audi historians have selected a total of 27 dates to commemorate in 2025. Twenty-five years ago, the Audi A2 hit the market. With its aluminum body, it made a name for itself as a progressive compact car: light, aerodynamic, and economical. The Audi A2 polarized opinion with its design and unusual proportions; the concept was ahead of its time. However, sales remained below expectations, and Audi ended production after roughly five years and 176,377 units built. Since then, the A2 became a fan favorite and is now a sought-after collector’s item. Sixty years ago, the first post–World War II Audi rolled off the production line. With the “Auto Union Audi” vehicle, Auto Union GmbH revived the tradition-steeped Audi brand name in 1965. The new name was meant to show that this car represented a fresh start for Auto Union in terms of technology. The Audi was the first car from the brand with four rings to feature a four-cylinder four-stroke engine, and it marked the beginning of a new era in Ingolstadt. Twenty years later, on January 1, 1985, Audi NSU Auto Union AG was renamed AUDI AG, and since that time, the company and its products have shared the same short, memorable name. Ninety years ago, in February 1935, a spectacular attempt to break speed records took place in Italy. After test drives in October 1934 with the Grand Prix racing car on the AVUS in Berlin, the Auto Union racing department started developing the vehicle that would later be known as the “Lucca” car.

Aerodynamics in automotive manufacturing from 1945 to the present day: from concept cars and record-breaking models to race cars and the Cd world champion, the Audi 100 Almost 30 exhibits feature in a special exhibition from July 25, 2024, to March 2, 2025 Audi wrote engineering history in 1982 with the Audi 100. With its drag coefficient of 0.30, the third-generation Audi 100 was the world’s most aerodynamically efficient production saloon at the time, making it an essential part of the new special exhibition "Form vollendet". The new special exhibition will be at the Audi museum mobile in Ingolstadt until March 2, 2025, where Audi Tradition will present aerodynamic concepts from 1945 to the present day. The aerodynamics research that flourished before the Second World War and which was the subject of Audi Tradition’s “Windschnittig” exhibition (German for “streamlined”) that ran until the end of June received little attention after 1945. Europe’s automotive industry was busy getting back on its feet. During this period, pre-war developments were still in use and improved upon. It wasn’t until the rising cost of fuel during the 1973 oil crisis prompted a shift in thinking that automotive engineers began focusing on reducing fuel consumption. One of the dials used to achieve this was aerodynamic drag. In 1982, Audi made a splash with the Audi 100; its drag coefficient of 0.30 set a world record for production sedans, a value that would become the benchmark for years to come. The new Audi Tradition special exhibition “Form vollendet” (German for “form perfected”) showcases the Cd world champion Audi 100 alongside other models such as the NSU Ro 80, the Porsche 356, the Lamborghini Countach, and the Ducati Paso 950.

Five-cylinder engine delivering 136 hp presented for the first time in 1976 in the Audi 100 Successful engine concept for series production and rallying 2.5 TFSI voted “Engine of the Year” seven times in a row since 2010 40 years ago, Audi presented the first five-cylinder gasoline engine in the second-generation Audi 100. Enhancements and new developments followed, with turbocharging, emissions control and four-valve technology, rally engines and five-cylinder diesel units. Today, the 2.5 TFSI in the Audi RS 3 Sportback* and in the Audi TT RS* carries on the great tradition of five-cylinder powerplants. The five-cylinder engines from Audi have achieved cult status – partly due to their successful deployment in motorsport and also on account of their reliability and economy. They have played a vital role in defining Vorsprung durch Technik and to this day provide an emotional driving experience with their characteristic sound. The first five-cylinder gasoline engine powered the Audi 100 (C2) in 1976. The model, known internally as Type 43, was to be positioned higher than its predecessor in the market. The four-cylinder engines at the time were not suitable for this plan according to the developers. At the beginning of the 1970s, Audi engineers consequently discussed the possibility of introducing five and six-cylinder inline engines. The latter were ruled out due to the installation space required and unfavorable weight distribution. So those responsible opted for the five-cylinder inline engine, based on the new EA 827 engine concept. This four-cylinder inline engine was used throughout the VW Group in the 1970s – in the Audi 80 and Audi 100, for instance. The derived 2.1-liter five-cylinder engine produced 100 kW (136 hp). A modern injection system increased efficiency and power development. Delivery of the Audi 100 5E began in March 1977.

Inspired by Bauhaus: Coupé study from 1995 began series production in 1998 178,765 first-generation Audi TT Coupés had rolled off the production line by 2006 Audi designer Torsten Wenzel introduced the study to series production: “The Audi TT is a driving sculpture” Twenty-five years, three generations: The brand with the four rings wrote design history with the Audi TT. Since its debut in 1998, the sports car has struck a chord with people worldwide thanks to the fun it promises drivers and its clear design language. „Auto Europe“ voted it the best new car of the year in 1999. In the mid-1990s, the Audi A8 luxury model elevated the Audi brand to a higher position and gradually led to the renaming of the model series: The Audi 80 became the Audi A4, and the Audi 100 was dubbed the Audi A6. Introduced in 1994, the Audi A4 was the first model to embody Audi’s new design language. Next was the Audi A3 premium compact car, launched in 1996, and the second generation of the Audi A6, introduced in 1997. In the course of emotionalizing the brand through a fresh, progressive design, American designer Freeman Thomas, under the then Head of Design Peter Schreyer, created a puristic sports car in the Audi TT Coupé. Audi presented the study to an enthusiastic trade show audience at the IAA in Frankfurt in September 1995. The model name “TT” is reminiscent of the legendary Tourist Trophy on the Isle of Man, one of the oldest motorsports events in the world and one where NSU and DKW celebrated great successes with their motorcycles. The name “TT” also recalls the sporty NSU TT of the 1960s. The Audi TT Coupé’s deliberate departure from the usual Audi nomenclature underscored the complete novelty of the model. Designer Wenzel: “In the Audi TT, every shape has a clear function” In December 1995, the decision was made to mass-produce the Audi TT Coupé.

Five-cylinder engine delivering 136 hp presented for the first time in 1976 in the Audi 100 Successful engine concept for series production and rallying Audi RS 3: modified five-cylinder engine with more torque Audi presented the first five-cylinder gasoline engine 45 years ago in the second-generation Audi 100. Enhancements and new developments followed with turbocharging, exhaust gas purification and four-valve technology, rally engines, and five-cylinder diesel units. The 2.5 TFSI won the “International Engine of the Year” award nine times in a row. Today, the high-performance engine in the new Audi RS 3 Sportback carries on the five-cylinder engine tradition – with more power than ever. The five-cylinder engines from Audi have achieved cult status – partly due to their successful deployment in motorsport and also on account of their reliability and economy. The engine’s unique 1-2-4-5-3 ignition sequence and the incomparable sound that comes with it make the driving experience so exhilarating. The first five-cylinder gasoline engine powered the Audi 100 (C2) in 1976.

Parallels between Valencia and the EuroSpeedway A look at the results of the past few years shows that the EuroSpeedway Lausitz has not exactly been the best track for the Audi A4 DTM. But thanks to the most recent experiences in Valencia this situation might change – because there are some parallels between the two circuits. The commonalities are mainly related to the aspect of tarmac quality. “The track at Valencia offers only little grip,” analyzes Dr. Martin Mühlmeier, Head of Technology at Audi Sport. “A very similar situation exists on the tarmac of the EuroSpeedway, which is smooth and not very porous. Obviously, we’re hoping to be able to make efficient use of our findings there again. At Valencia we were rewarded for our effort of very carefully studying the tires. Despite the high track temperatures there we managed to combine very good performance with top durability in our set-up.” From Lausitz to Le Mans Immediately after crossing the finish line at the EuroSpeedway Lausitz three of the nine Audi drivers will embark on their next major commitment. As early as on the evening of race day Oliver Jarvis, Mike Rockenfeller and Timo Scheider will fly to France to contest the Le Mans 24 Hours. Mike Rockenfeller will drive one of the Audi R15 TDI cars entered by Audi Sport Team Joest. Oliver Jarvis will compete in an Audi R10 TDI of the private Kolles team. Timo Scheider will make his Le Mans debut at the wheel of a GT2 Porsche. Other topics of the weekend • Will Audi manage to bring about a change at the top of the standings? • Will skillful handling of the tires influence the balance of power between the manufacturers again at the EuroSpeedway, which offers very low grip? • Which manufacturer will be the first to achieve two wins this season? • Will rookie Miguel Molina score points for the third consecutive time? • Will over 70,000 spectators turn out for the DTM round at Lausitz, as they have every year since 2006?

Successful for decades: 662,762 units across three generations built over 25 years Design inspired by Bauhaus: every shape has a clear function Vorsprung durch Technik: New technologies launched with the TT, including Audi magnetic ride, Audi virtual cockpit, and OLED technology A quarter of a century of TT history: When Audi presented the concept car at the IAA in 1995, public opinion became clear right away: “This car should be mass-produced – exactly as it is!” With the series debut in 1998, the Audi TT wrote design history and was built across three generations as a Coupé and Roadster. With a vision of “a car for enthusiasts,” Audi presented the Audi TT Coupé as a sports car concept at the IAA in Frankfurt in the fall of 1995. Shortly afterward, the decision was made to mass-produce it. Torsten Wenzel, the exterior designer at Audi who helped introduce the study to series production, recalls: “To us, the greatest praise was when the trade press noted appreciatively that not much had changed from the concept to production model, although we did, of course, have to adapt many details due to the technical specifications for the production version, including the proportions.” Most noticeable was the integration of a rear side window, which elongated the car’s profile and increased the sports car’s dynamics. For Wenzel, the TT remains “a driving sculpture, with highest-quality surfaces and lines.” The body of the Audi TT appears to be made from one piece, Wenzel says, and the front end without traditional bumper overhangs emphasizes its distinctive shape. Another design element contributes to the unmistakable silhouette of the Audi TT Coupé: the circle – “the perfect graphic shape,” as Wenzel describes it. Numerous circular elements inspired the sports car’s exterior and interior design. Inspired by Bauhaus, every line in the Audi TT has a purpose, every shape a function. “At Audi Design, we always follow the philosophy of ‘less is more.’

In the anniversary year of 2023, Audi Tradition will bring out a number of NSU highlights from AUDI AG’s historical vehicle collection for events. Ten-part series with classic and exotic cars from NSU’s product history The traditional NSU brand is celebrating its birthday. In 1873, Christian Schmidt and Heinrich Stoll founded “Mechanische Werkstätte Schmidt & Stoll” in Riedlingen for the production of knitting machines, which later evolved into NSU Motorenwerke AG and ultimately into today’s Audi site in Neckarsulm. Even NSU’s name is closely associated with Neckarsulm, as the company name is derived from the city on the Neckar and Sulm rivers. NSU impressively demonstrates the development of mobility – from bicycles and motorcycles to automobiles. For its 150th anniversary, Audi Tradition is bringing out a number of NSU highlights from its historical vehicle collection. The special exhibition “Innovation, audacity and transformation”, a cooperation project between Audi Tradition and the German Bicycle and NSU Museum (Deutsches Zweirad- und NSU-Museum), is also under construction. The exhibition will be on display at the Audi Forum in Neckarsulm and at the German Bicycle and NSU Museum in Neckarsulm starting on June 14. “There are so many stories to tell from the long history of NSU,” said Tobias Fräbel, an employee at Audi Tradition responsible for the corporate archives of the Neckarsulm site and the NSU brand. “Since we can’t tell all the stories in just one text, Audi Tradition will offer stories and background information about the company, its products, its involvement in racing and much more throughout the year.” These posts can be found on Audi Tradition’s Instagram channel and in the Audi MediaCenter. There, Audi Tradition will launch a ten-part series. From March to December, one NSU model will be introduced every month – from the brand’s classics, whether they have two or four wheels, to prototypes and exotic models.
