The traditional NSU brand and the Audi Neckarsulm site: 150 years of innovation and transformation

“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. If that’s not enough for you, you can naturally delve even deeper into the moving, multifaceted history of the traditional brand – for instance, through Klaus Arth’s Audi Tradition book “NSU-Automobile. Typen – Technik – Modelle”, published by Delius Klasing, or Peter Schneider’s book “Die NSU-Story”, published by Motorbuch-Verlag.

Fast-forward: The history of the traditional NSU brand

Founded in Riedlingen in 1873 by Christian Schmidt and Heinrich Stoll as a manufacturer of knitting machines, the company relocated to Neckarsulm in 1880, where it was converted into a joint-stock company in 1884. In 1886, the Neckarsulm company struck at the right time. Bicycles were becoming more and more popular, and NSU started producing and selling more and more of them from then on. Starting in 1900, the company began manufacturing motorcycles as well. The new brand name of N.S.U. (from NeckarSUlm) was suddenly becoming popular all over the world. In 1906, the first Original Neckarsulmer Motorwagen – a small mid-range car with a water-cooled four-cylinder engine – was introduced to the public. In 1909, 1,000 employees manufactured 450 automobiles. The Neckarsulm-based car maker first made automotive history with regard to lightweight construction in 1914, when Neckarsulm engineers built the NSU 8/24 PS with an aluminum body.

Despite the First World War and subsequent devaluation in the hyperinflationary year of 1923, NSU initially continued to do well financially. In 1923, 4,070 employees produced one car every two hours, one motorcycle every 20 minutes and one bicycle every five minutes. In 1924, the company invested in a new plant for automobile construction in Heilbronn in order to gain more space. Two years later, however, sales declined for the first time, which resulted in money problems. In 1929, NSU was forced to cease its automobile production and sell the nearly new plant in Heilbronn to Fiat. Fiat built cars there under the name NSU-Fiat until 1966. From then on, Neckarsulm focused on the production of two-wheelers, took over a majority of Wanderer’s motorcycle division in 1929 and established a sales cooperation with the brand D-Rad in Berlin in 1932. Alongside BMW and DKW, NSU was one of the most important German motorcycle brands in the 1930s. After it took over Opel’s bicycle production at the end of 1936, it became one of the largest manufacturers of two-wheelers in Germany. In 1933/34, NSU built three prototypes of a vehicle designed by Ferdinand Porsche with an air-cooled 1.5-liter boxer engine in the rear. In its basic conception, this car was similar to the later VW Beetle. However, it was not mass produced due to financial reasons. By the end of the war in May 1945, large portions of the Neckarsulm plant facilities were in ruins.

Reconstruction after the Second World War followed with the popular NSU bicycles and the 98-cc NSU Quick moped. A 125- and 250-cc model were added soon after. Later came the NSU Fox, the NSU Lux, the NSU Max and the NSU Konsul, with 500 ccs of engine displacement. With an annual production of almost 300,000 motorized two-wheelers (mopeds, motorcycles and scooters), the Neckarsulm-based company shot to the top of the international motorcycle industry in 1955. It was the largest two-wheeler plant in the world. Despite all the NSU motorcycles’ successes, which brought the company worldwide fame with wins in five motorcycle world championships between 1953 and 1955 and numerous world speed records, the corporate management had to respond to declining motorcycle demand starting in the mid-1950s. With increasing prosperity, customers wanted to drive cars, so it was time for NSU to start producing automobiles again.

NSU managed to resume automobile construction in 1958 with the Prinz compact car. Technical innovations soon emerged. NSU had been working on a 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 at an NSU testing station.

In 1963, the Neckarsulm-based company introduced the NSU Wankel Spider at the IAA in Frankfurt, thus writing automotive history. It was the world’s first series-production automobile powered by a single-rotor rotary engine, with 497 ccs and 50 hp. The next sensation followed in the fall of 1967, when the Neckarsulm-based company introduced the NSU Ro 80 at the IAA in Frankfurt, thrilling the automotive world. The car was powered by a dual-rotor NSU/Wankel rotary engine (115 hp), and its revolutionary design attracted a lot of attention. Also in 1967, the NSU Ro 80 became the first German automobile to be voted Car of the Year.

On March 10, 1969, a contract was signed to merge NSU Motorenwerke AG and the Ingolstadt-based Auto Union GmbH under the umbrella of the Volkswagen Group. With retroactive effect from January 1, 1969, AUDI NSU AUTO UNION AG was 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. In addition to the NSU Prinz and
NSU Ro 80, the Audi 100 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 Ro 80 in 1977, after ten years. Finally, on January 1, 1985, AUDI NSU AUTO UNION AG was 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 and one’s products – this is part of the history of NSU and Audi’s Neckarsulm site. It has developed both rapidly and continually in recent decades. With its expertise in large- and small-scale production, the Neckarsulm plant currently ranks among the most complex in Europe, and it’s one of the locations with the greatest product diversity in the Volkswagen Group. The site is gradually evolving into a smart factory, and it’s preparing for electrification. It’s also the center of expertise in high-voltage batteries. In addition to the Audi A8 flagship, the Audi R8 super sports car and other models in the B, C and D series, the sporty RS models are developed and manufactured in Neckarsulm as well – and not without reason, as this is where Audi Sport GmbH is based. This company traces its lineage back to the founding of quattro GmbH in 1983, meaning it will celebrate its 40-year anniversary in 2023. Since the end of 2020, the first all-electric Audi model made in Germany is also manufactured here: the Audi e-tron GT quattro. With around 15,500 employees at the Neckarsulm site, AUDI AG is currently one of the biggest companies in the economic region of Heilbronn-Franken. Everything started 150 years ago with ten employees – what a history, what dynamism, what a development!

Exciting chapter in NSU advertising: Creative, innovative, groundbreaking

“Fixe Fahrer fahren Fox”, “Kluge Köpfe kaufen Konsul”, “Nicht mehr laufen – Quickly kaufen!” – a lot of NSU advertising slogans are legendary. In his book “Fahre Prinz und du bist König. Geschichten aus der NSU-Geschichte” (Drive Prinz and You’re a King: Stories from NSU’s History), NSU’s former head of advertising Arthur Westrup explains that NSU didn’t have a lot of money on hand in the 1950s, which made him and his team all the more creative. In addition to their catchy phrases, the marketing experts came up with special campaigns.

For instance, a special ad for the NSU Quickly appeared on the back of the BILD newspaper every Monday, sometimes addressing current issues. One ad after an international match between Germany and England read: “You see the beaten players heading home from Berlin, and all the strikers wanly groan, ‘Blessed is he who has a Quickly!’” Another big advertising hit came in the year 1971. “Ro 80. Vorsprung durch Technik.” was written in big letters on the advertising poster for the NSU Ro 80. The famous Audi slogan was thus created in NSU’s Advertising department. It would stick in people’s minds worldwide: “Vorsprung durch Technik.”

Active in racing: Neckarsulm brings home victories and records

NSU can look back on a long and successful history in motorsport – both before and after the Second World War. Here’s a small assortment: With the 500-cc NSU racing motorcycle, the English rider Tom Bullus won the Grand Prix of Germany for Motorcycles (Großen Preis von Deutschland für Motorräder) at the Nürburgring in 1930. After Bullus won numerous other races and the Grand Prix of Nations (Großen Preis der Nationen) in Monza in record time with the NSU 500 SSR, his motorcycle was talked about as the most successful German racing bike. Between 1931 and 1937, NSU won German championships 11 times and Swiss championships five times. The “Bullus”, as fans called the NSU 500 SSR, was also available as a street sport bike – although with less power.

In the 1950s, NSU once again brought home nonstop victories. In 1950, Heiner Fleischmann (on a supercharged 500-cc NSU racing bike) and Hermann Böhm with Karl Fuchs in his sidecar (on a 600-cc motorcycle) both became German champions in their respective classes. Starting in the 1951 season, superchargers were no longer allowed in motorcycle racing, but the supercharged NSU bikes lived on. With streamlined fairings optimized in a wind tunnel and extended chassis, Wilhelm Herz became the fastest man in the world on a two-wheeler in 1951 and 1956, at 290 and 339 km/h, respectively. Thanks to their resemblance to whales and dolphins, the NSU racing bikes were soon to be called Rennfox Typ Delphin and Rennmax Typ Blauwal – and they won nearly everything there was to win in motorcycle racing at the time. NSU’s wins at the Tourist Trophy (TT) in 1954 were legendary as well. The factory team on the Isle of Man included Werner Haas, H.P. Müller, Hans Baltisberger and Rupert Hollaus. Hollaus finished the race, considered the most dangerous motorcycle race in the world, as the winner in the 125-cc class. Haas, Hollaus, Armstrong and Müller took first through fourth place in the class up to 250 ccs.

NSU also consistently scored victories on four wheels. Here are a few highlights from several decades: In 1926, four supercharged NSU 6/60 PS race cars took a quadruple win at the Grand Prix of Germany for Sports Cars (Großen Preis von Deutschland für Sportwagen) at the AVUS in Berlin. In the 1960s and 70s, the NSU Prinz, the NSU Wankel Spider and the NSU TT put their technical skills to the test in touring car racing, thrilling millions of spectators at racetracks all over the world. And one little guy always came out on top: the NSU Prinz TT. With this model, a total of 29 national championships were won in Europe and North America, while Willi Bergmeister became the German hill-climb champion in 1974.
