Booklet features a selection of more than two dozen anniversaries The launch of the Audi A2 25 yearsago; the first new Audi in post-war times 60 yearsago; andHans Stuck’s record-breaking exploits in the “world’s fastest road-goingcar” near Lucca 90 yearsago
With the “Anniversary Dates 2025” booklet, Audi Tradition is showcasing the most important moments in the product and company history of Audi, which isas eventful asitis diverse. Audi historians have selected a total of27 dates to commemorate in 2025.
Twenty-five yearsago, 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 ofits time. However, sales remained below expectations, andAudi ended production after roughly five years and 176,377 units built. Since then, the A2 became afan favorite and is now a sought-after collector’s item. Sixty yearsago, the first post–World WarII 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 ofa new erain Ingolstadt. Twenty years later, on January 1, 1985, Audi NSU Auto Union AGwas renamed AUDI AG, and since that time, the company and its products have shared the same short, memorable name. Ninety yearsago, 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 caron the AVUSin Berlin, the Auto Union racing department started developing the vehicle that would later be known as the “Lucca” car.
Five-cylinder engine delivering 136hp presented for the first time in 1976 in the Audi100 Successful engine concept for series production and rallying 2.5 TFSI voted “Engine of the Year” seven times ina row since 201040 yearsago, Audi presented the first five-cylinder gasoline engine in the second-generation Audi100. 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 RS3 Sportback* and in the Audi TTRS* 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 andto this day provide an emotional driving experience with their characteristic sound. The first five-cylinder gasoline engine powered the Audi100 (C2) in 1976. The model, known internally as Type 43, wastobe 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 EA827 engine concept. This four-cylinder inline engine wasused throughout the VW Group in the 1970s – in the Audi 80andAudi100, for instance. The derived 2.1-liter five-cylinder engine produced 100 kW (136hp). A modern injection system increased efficiency and power development. Delivery of the Audi100 5E began in March 1977.
Aerodynamics in automotive manufacturing from 1945 to the present day: from concept carsand record-breaking models to race carsand the Cd world champion, the Audi100 Almost 30 exhibits feature ina special exhibition from July25, 2024, to March 2, 2025
Audi wrote engineering history in 1982 with the Audi100. With its drag coefficient of 0.30, the third-generation Audi100 was the world’s most aerodynamically efficient production saloon at the time, making itan 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 Warand 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 wasbusy getting back onits feet. During this period, pre-war developments were still inuseand 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. Oneof the dials usedto achieve this was aerodynamic drag. In 1982, Audi madea splash with the Audi100; its drag coefficient of 0.30 set a world record for production sedans, a value that would become the benchmark for yearsto come. The new Audi Tradition special exhibition “Form vollendet” (German for “form perfected”) showcases the Cd world champion Audi100 alongside other models such as the NSU Ro80, the Porsche 356, the Lamborghini Countach, and the Ducati Paso 950.
Five-cylinder engine delivering 136hp presented for the first time in 1976 in the Audi100 Successful engine concept for series production and rallying Audi RS3: modified five-cylinder engine with more torque
Audi presented the first five-cylinder gasoline engine 45 yearsagoin the second-generation Audi100. 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 ina row. Today, the high-performance engine in the new Audi RS3 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 Audi100 (C2) in 1976.
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 by2006Audi designer Torsten Wenzel introduced the studyto series production: “The Audi TTisa 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 carhas struck a chord with people worldwide thanks to the fun it promises drivers and itsclear design language. „Auto Europe“ voted it the best new carof the year in 1999.
In the mid-1990s, the Audi A8 luxury model elevated the Audi brand toa higher position and gradually led to the renaming of the model series: The Audi 80 became the Audi A4, and the Audi100 was dubbed the Audi A6. Introduced in 1994, the Audi A4was 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 Headof Design Peter Schreyer, created a puristic sports carin the Audi TT Coupé. Audi presented the studytoan enthusiastic trade show audience at the IAAin Frankfurt in September 1995. The model name “TT” is reminiscent of the legendary Tourist Trophy on the Isle ofMan, oneof the oldest motorsports events in the world andone where NSU and DKW celebrated great successes with their motorcycles. The name “TT” also recalls the sporty NSU TTof 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 hasaclear function” In December 1995, the decision was made to mass-produce the Audi TT Coupé.
Successful for decades: 662,762 units across three generations built over 25 years Design inspired by Bauhaus: every shape hasaclear function Vorsprung durch Technik: New technologies launched with the TT, including Audi magnetic ride, Audi virtual cockpit, andOLED technology
A quarter ofa century ofTT history: When Audi presented the concept carat the IAAin 1995, public opinion became clear right away: “This car should be mass-produced – exactly asitis!” With the series debut in 1998, the Audi TT wrote design history andwas 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 IAAin 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 studyto series production, recalls: “Tous, 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 ofa 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 bodyof the Audi TT appears tobe 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 TThasa purpose, every shape a function. “At Audi Design, we always follow the philosophy of ‘less is more.’
NSU had been working ona completely new engine concept with Felix Wankel since the beginning of the 1950s. In 1957, a Wankel-type rotary piston engine fired its ignition for the first time atan NSU testing station. In 1963, the Neckarsulm-based company introduced the NSU Wankel Spider at the IAAin Frankfurt, thus writing automotive history. Itwas the world’s first series-production automobile powered bya single-rotor rotary engine, with 497 ccsand50hp. The next sensation followed in the fall of 1967, when the Neckarsulm-based company introduced the NSU Ro80at the IAAin Frankfurt, thrilling the automotive world. The carwas powered bya dual-rotor NSU/Wankel rotary engine (115hp), and its revolutionary design attracted a lot of attention. Also in 1967, the NSU Ro80 became the first German automobile tobe voted Carof the Year. On March 10, 1969, a contract was signed to merge NSU Motorenwerke AGand the Ingolstadt-based Auto Union GmbH under the umbrella of the Volkswagen Group. With retroactive effect from January 1, 1969, AUDI NSU AUTO UNION AGwas created with its headquarters in Neckarsulm, and Volkswagenwerk AG held a majority interest. The new company’s model range was greatly varied, even from a technical point of view. Inadditionto the NSU Prinz and NSU Ro80, the Audi100 was also built at the Neckarsulm site from then on. However, the two NSU models were phased out in the 1970s – the Prinz in 1973, after 15 years, and the Ro80in 1977, after ten years. Finally, on January 1, 1985, AUDI NSU AUTO UNION AGwas renamed AUDI AG, and the company’s headquarters were moved from Neckarsulm to Ingolstadt. The company and products have borne the same name ever since. Transformation, constantly reinventing oneself andone’s products – this is part of the history of NSU andAudi’s Neckarsulm site. Ithas developed both rapidly and continually in recent decades.
