A NSU Prinz in 2007

The NSU Prinz is an automobile which was produced from 1958 to 1973 in West Germany by the NSU Motorenwerke AG which in the mid 1950s had been the biggest motorcycle producer in the world. The production of German motorcycles declined sharply as customers needed weather protection for daily driving, with demand shifting first towards microcars and then towards affordable cars.

NSU's first post-war car, the Prinz I, was launched at the Frankfurt Motor Show in September 1957 with the advertising slogan "Fahre Prinz und Du bist König" ("Drive a Prince and you're a king").[4] After a pilot run of 150 preproduction cars, volume production began in March 1958.[5]

The Prinz I was available as a two-door saloon[6] featuring an upright roof line and seating for four people. The doors opened wide enough to permit reasonable access even to the rear seats, although leg room was severely restricted if attempting to accommodate four full sized adults.[2] In addition to a luggage compartment accessed via a hatch at the front of the car and shared with the spare wheel and fuel filler, there was a narrow but deep full width space behind the rear seat sufficient to accommodate a holiday suitcase.

The Prinz was exported to the United States, but did not sell well and was dropped after 1960.[7] The Prinz was also famously used by an US astronaut. While others chose Chevrolet Corvettes that were offered to them by GM, Mercury astronaut John Glenn used the Chevrolet connection to lease a station wagon to haul his kids around in, while using an NSU Prinz 1 as daily driver. The Prinz got better fuel mileage than the Chevrolet, and as Glenn had a longer commute than his fellow astronauts, the more economical Prinz allowed him to save for his children’s college fund.[2]

The noisy[2] two-cylinder 600 cc 20 PS (14.7 kW; 19.7 hp) air-cooled engine was located at the back where it drove the rear wheels, initially via a "crash" gearbox. Later versions gained a four-speed all-synchromesh gearbox. Contemporaries were impressed by the brevity of the maintenance schedule, with the engine, gear box and final drive operating as a single chamber and all lubricated by means of oil, added through a filler in the rocker box cover.[2] There were just two grease nipples requiring attention, positioned on the steering kingpins.[2] The engine was also commended in contemporary reports for its fuel economy and longevity.[2] Although noisy, the engine offered impressive flexibility, recalling NSU's strengths as a motorcycle manufacturer.[2]

The Prinz II was a more 'luxurious' version[8] released in 1959, with better trim and an all-synchromesh gearbox.[9] A 30E export version was equipped with a 30 PS (22.1 kW; 29.6 hp) engine.[9] The Prinz III was launched in October 1960[10] featuring a new stabilizer bar and the 30 hp motor.[9]

NSU received government approval to build the Prinz in Brazil in the late 1950s, but nothing came of the project.[11]

The Sport Prinz was a 2-seater sports coupe variant.[12] It was designed by Franco Scaglione at Bertone studios in Turin. 20,831 were manufactured between 1958 and 1968.[12] The first 250 bodies were built by Bertone in Turin. The rest were built in Heilbronn at Karrosseriewerke Drauz which was later bought by NSU.

The Sport Prinz was initially powered by the 583 cc (35.6 cu in) Prinz 50 straight-twin engine but a maximum speed of 160 km/h (99 mph) was nevertheless claimed. From late 1962 a 598 cc (36.5 cu in) engine was fitted.[12]

The NSU Spider was a Wankel rotary powered two-seater roadster based on the Sport Prinz platform.[12]

One of the revelations of the Frankfurt Motor Show in September 1961,[15][16] the Prinz 4 replaced the original Prinz. Its new body closely resembled the then fashionable Chevrolet Corvair, but was of course much smaller. Like the original Prinz, it was powered by a two-cylinder air-cooled engine in the rear. The Prinz 4 was much improved and continued to be a well-engineered car, like its predecessors. The engine carried on the NSU tradition of an eccentric rod-driven camshaft inherited from their motorcycle engines, and had a dynastart (combined starter/generator) built into the crankcase. The dynastart also works as a flywheel of the engine. Later, four-cylinder engines adopted the more conventional (pre-engaged) separate starter motor and alternator.

In 1968, Britain's Autocar road tested a Super Prinz. They had tested a Prinz 4 in 1962, and in commenting on how little the car had changed in the intervening six years quipped some of their road testers appeared to have gained more weight than the commendably light-weight Prinz in that period.[13] The test car achieved a top speed of 70 mph (113 km/h) and accelerated to 60 mph (97 km/h) in 35.7 seconds.[13] The home grown Mini 850 reached 60 mph in 29.5 seconds in an equivalent contemporary test and also managed to beat the NSU's top speed, albeit only by about 3%.[13] At this time, the UK car market was heavily protected by tariffs, and the Prinz's UK manufacturer's recommended retail price was £597, which was more than the (possibly below cost)[citation needed] £561 asked for the 850 cc Mini, but certainly not completely out of touch with it.[13] The testers concluded their report that the car was competitively priced in its class and performed adequately.[13] They opined, cautiously, it offered 'no more than the rest' but neither did it 'lack anything important'.

The NSU Prinz evolved into the somewhat larger bodied NSU Prinz 1000 (Typ 67a), introduced at the 1963 Frankfurt Motor Show.[17][18] A sporting NSU 1000 TT (with a 1.1 litre engine) also appeared, which was later developed into the NSU (1200) TT[19] and NSU TTS[20] models. All had the same body with inline-four air-cooled OHC engines and were frequently driven as sports cars, but also as economical family cars as well. The mostly alloy engines were very lively, and highly reliable. The OHC arrangement was quite advanced for the time on a small family car as most home-grown cars were still using less efficient pushrod engines. The Prinz 1000 lost the "Prinz" part of the name in January 1967, becoming simply the NSU 1000 or 1000 C depending on the equipment. It has 40 PS (29 kW) DIN, while the 1200 TT has 65 PS DIN (48 kW) and the most potent TTS version has 70 PS DIN (51 kW) from only one litre.[14] The 1000 received large oval headlights, while the sportier TT versions have twin round headlights mounted within the same frame. The first 1000 TT has 55 PS (40 kW) DIN and uses the engine first introduced in the larger NSU Typ 110.

NSU Prinz 1000

The NSU Prinz 1000 TT was built in 14,292 examples between 1965 and 1967, when it was replaced by the bigger engined TT. This, with a 1.2-liter engine, was built until July 1972 for a total of 49,327 examples. The TT can be recognized by its broad black stripe between its headlights. The TTS was built especially for competition, being successful in both hillclimbs and circuit racing. It has a front-mounted oil cooler and was built in 2,402 examples from February 1967 until July 1971. It was briefly referred to as the "Prinz 1000 TTS" when first introduced. There was also a competition model of the TTS available for sale, with 83 PS DIN (61 kW).[17] Production of the Typ 67a (NSU 1000) came to a halt in December 1972.

In 1965, an even larger model was added, initially called Typ 110, and from 1967 on NSU 1200. It offered more space, so it was a better family car, but was not as sporty as the smaller models. Therefore, the NSU 1200TT used the 1200 cc engine of the 1200 in the smaller body of the NSU 1000.

1969 NSU TT

End of production

[edit]

NSU was acquired by Volkswagen in 1969 due to financial difficulties at NSU and merged with Auto Union AG. Auto Union had been taken over by VW in 1964 and was producing mid-sized cars under the revived Audi marque. The name of the new company was Audi NSU Auto Union AG. The small, rear-engined NSUs were phased out in 1973, as production capacity was needed for larger and more profitable Audis. Audi's contender in the Prinz' market segment was the front-wheel drive Audi 50, later rebadged as the Volkswagen Polo.

[edit]

The Prinz was manufactured under license in Sarajevo, Yugoslavia (now in Bosnia-Herzegovina), by PRETIS (Preduzeće Tito Sarajevo). Around 15,000 vehicles were made.[21]

The Prinz was also manufactured in Argentina by Autoar, making mainly models Prinz II and Prinz III / 30. A total of 2,432 units were built between 1959 and 1963. It is said[who?] that only 40-45 Sportprinz and fewer than ten Prinz IV were imported.[citation needed]

The Ramses was the first car produced in Egypt, and was the result of a co-operation between the new Egyptian car firm Egyptian Light Transport Manufacturing Company, and NSU. The factory was located right next to the Great Pyramids. Plans were to produce around 10,000 cars a year, most of the work being manual labor.[22]

The Prinz 4-cylinder air-cooled engine was also famously adopted by Friedl Münch in 1966 for the hand-built Münch Mammut motorcycle, at the time the fastest and most expensive motorcycle in production.

In Uruguay, the Prinz 4 was built by Nordex S.A., and a new model, the P6, combined the engine and mechanics of the NSU model with a separate body completely redesigned by Carlos Sotomayor. From 1970, the P10 was built as the successor model to the NSU P6. This had the larger engine of the NSU Prince 1000 and a 21 cm extended wheelbase.[23]

NSU Prinz

View on Grokipedia
from Grokipedia
The NSU Prinz was a series of compact, rear-engined economy produced by the German manufacturer AG from 1957 to 1973, designed to meet post-World War II demand for affordable, fuel-efficient personal transportation. Featuring a lightweight body and innovative engineering derived from NSU's heritage, the Prinz lineup emphasized simplicity, low operating costs, and nimble handling, with early models achieving up to 50 miles per gallon in highway driving. Introduced at the 1957 Motor Show under the "Fahre Prinz und Du bist König" ("Drive Prinz and you are king"), it marked NSU's return to automobile production after focusing primarily on since the late . The inaugural models—Prinz I, II, and III—were built from 1957 to 1962 and powered by a transversely mounted, air-cooled, two-stroke 583 cc producing 20 to 30 horsepower, paired with a four-speed and . These two-door sedans, seating four passengers, weighed around 1,100 pounds, reached a top speed of 62 mph, and returned exceptional fuel economy, making them popular for urban use and even selected by astronaut for their efficiency. Over 94,500 units were produced, with the design evolving slightly across variants to improve refinement and power delivery. Subsequent developments shifted to four-cylinder powertrains for greater performance and market competitiveness, starting with the Prinz 4 in 1961 and culminating in the Prinz 1000 (introduced in 1963), which used a 997 cc air-cooled inline-four delivering 43 to 50 horsepower. Variants like the sporty NSU TT (1967–1972) offered enhanced tuning with up to 70 horsepower, disc brakes, and a 0–60 mph time under 13 seconds, while maintaining the rear-engine layout and adding features such as improved suspension for better roadholding. Production of the four-cylinder Prinz models totaled approximately 526,000 units, including the Typ 110 and 1200 series, before NSU's acquisition by in 1969 led to the brand's phase-out by 1973. The Prinz's legacy endures as a symbol of NSU's ingenuity, bridging the gap between microcars and larger family vehicles during Germany's .

Background and Development

Historical Context

NSU AG originated in 1873 as a producer of machines in Riedlingen, , before relocating to and shifting to bicycle manufacturing in 1886 and motorcycles in 1900. By the early , NSU had expanded into automobiles, producing its first car in 1905, but financial pressures from the led to the cessation of car production in 1929, with the company refocusing on motorcycles and small engines. Pre-World War II, NSU became Germany's leading motorcycle brand, renowned for innovations in two-stroke and four-stroke engines, and even contributed to early prototypes like the NSU/ Type 32, a precursor to the . Following the devastation of , which left NSU's facilities in ruins, the company rebuilt rapidly by resuming production of bicycles in 1946, followed in the late 1940s and early 1950s by mopeds such as the 98-cc Quick (1952) and 49-cc Quickly (1953), as well as motorcycles like the (1949), Lux, Max, and 500-cc Konsul (1951). By 1955, NSU had become the world's largest manufacturer of two-wheeled vehicles, producing nearly 300,000 units annually and employing thousands in the region. However, as motorcycle sales began to decline amid shifting consumer preferences, NSU sought to reenter the automobile sector to capitalize on emerging opportunities. The 1950s in were defined by the , or , a period of explosive growth following postwar reconstruction, with GDP rising at an average of 8% annually and unemployment falling below 1% by the decade's end. This boom, supported by currency reform, Allied aid, and export-driven industry, spurred widespread demand for affordable personal mobility among the expanding , as car ownership symbolized prosperity and independence. Passenger car registrations skyrocketed from around 500,000 in 1950 to over 8.6 million by 1965, with small, fuel-efficient economy cars like the dominating sales due to their low cost and practicality on improving road networks. In response to these market dynamics, NSU initiated development of a compact rear-engined in 1955, aiming to rival successes like the and Fiat 600. Prototypes emerged in 1956, and the resulting NSU Prinz was unveiled at the 1957 Motor Show with the "Fahre Prinz und du bist König" (Drive a Prince and you're a King), emphasizing its accessibility and appeal. Volume production commenced in March 1958 at the plant, with the base Prinz I model priced at 3,650 Deutsche Marks to attract budget-conscious buyers during the height of the economic upswing. NSU targeted an initial output of 5,000 units per month, reflecting ambitions to capture a significant share of the burgeoning small-car segment.

Design and Engineering Origins

The NSU Prinz series drew heavily from the company's longstanding engineering heritage, particularly in the development of its . The core innovation was the rear-mounted, air-cooled two-cylinder engine, adapted from NSU's successful designs like the Max, which emphasized reliability and simplicity for . This layout allowed for a compact while optimizing and freeing up interior space, aligning with demands for economical urban transportation. The engine itself incorporated advanced features for its era, including a single overhead (SOHC) for improved efficiency and power delivery from the 583 cc displacement. Lightweight aluminum construction for the and contributed to better fuel economy and reduced overall vehicle weight, enhancing the car's nimble handling without compromising durability. Structurally, the Prinz utilized a self-supporting all-steel body with a boxy, utilitarian aesthetic that prioritized functionality over flair, providing ample room for four passengers in a compact . The featured a rigidly braced platform in early configurations, paired with fully —double wishbones at the front and swing axles at the rear—to deliver stable ride characteristics suited to varied road conditions. Subsequent evolutions introduced MacPherson struts at the front for further refinement. Practicality was a key engineering focus, with a of approximately 2,000 mm enabling a surprisingly spacious cabin relative to the exterior dimensions, including sufficient rear seating and luggage area. Safety and comfort elements included coil springs on all corners for smoother , and an optional heater system to mitigate the air-cooled engine's limitations in colder climates.

Two-Cylinder Models

Prinz I, II, and III

The NSU Prinz I, introduced in 1958, marked the debut of the rear-engined saloon as NSU's entry-level , powered by a 583 cc air-cooled two-cylinder producing 20 hp at 5,400 rpm. This configuration enabled a top speed of approximately 110 km/h while delivering of 5.5 L/100 km, emphasizing practicality for everyday commuting in . The design prioritized simplicity, with the mounted transversely at the rear driving the rear wheels via a four-speed manual gearbox. In 1960, the Prinz II succeeded with refinements for better drivability, including the same 583 cc version of the two-cylinder engine now outputting 20 hp (24 hp SAE). Key updates encompassed an improved all-synchromesh gearbox for smoother shifts and minor styling changes, such as revised bumpers and enhanced chrome trim, to appeal to a broader market without altering the core mechanical layout. The Prinz III arrived in October 1960, building on prior models with a power increase to 30 hp from the refined two-cylinder engine, alongside the adoption of hydraulic drum brakes for improved stopping performance. All three models shared a compact two-door saloon body configuration seating four passengers, measuring 3,150 in length and 1,420 in width, which contributed to their nimble handling and urban suitability. Notably, in 1962, American astronaut selected a Prinz as his personal vehicle, favoring its exceptional fuel economy over flashier options like the provided to his Mercury program colleagues. However, U.S. sales remained dismal, hampered by sluggish acceleration—with 0-100 km/h taking 37 seconds—making it uncompetitive against domestic compacts.

Sport Prinz

The NSU Sport Prinz was introduced as a sporty two-seater variant of the Prinz lineup, debuting at the 1958 Motor Show. Designed by at the Bertone studios in , it featured a sleek, aerodynamic all-steel body with Italian-inspired styling that echoed the Sprint, including a low roofline measuring 1,235 mm in height for enhanced sporty appeal. Early bodies were built by Carrozzeria Bertone before production shifted to NSU's facilities in , emphasizing a rigid derived from the standard Prinz but adapted for coupe configuration with limited luggage space under the front bonnet and behind the seats. Power came from an air-cooled, two-cylinder overhead-camshaft mounted at the rear, starting with a 583 cc unit producing 20 hp at 4,600 rpm in the early models. By 1961, an updated 598 cc version increased output to 30 hp at 5,500-5,800 rpm, paired with a single for improved responsiveness, though fuel consumption hovered around 39-47 . Performance included a top speed of approximately 125 km/h and 0-100 km/h in about 23-26 seconds, suitable for spirited driving but modest by standards. enhancements for better handling comprised a stiffer suspension with swing axles, larger drum brakes (hydraulic with some fade under hard use), and a four-speed synchromesh gearbox, which provided adequate but notchy shifts and contributed to the car's nimble, oversteering character, particularly in wet conditions. Production spanned from to , totaling 20,831 units, with the model priced around $2,395 in the U.S. market upon its export introduction. A 1964 variant, the Sport Prinz Deluxe, added luxury touches such as chrome trim accents and reclining bucket seats to appeal to a broader seeking style over outright performance. The coupe's compact dimensions—3,560 mm and 556-680 kg curb weight—made it agile on winding roads, though its rear-engine layout demanded careful handling to manage the tail-happy tendencies. In racing, the Sport Prinz saw limited but enthusiastic privateer use in hill climbs and local rallies during the early , where owners tuned the to over 50 hp for . Its lightweight construction and responsive earned praise for nimble cornering and ease of modification, though the modest power output restricted it to class-level successes rather than outright victories against more potent rivals. Production ended in to prioritize NSU's shift toward four-cylinder models and the Wankel-powered Ro 80, marking the Sport Prinz as a brief but stylish footnote in the company's automotive history.

Four-Cylinder Models

Prinz 4

The NSU Prinz 4 was launched in 1961 as an update to the Prinz saloon series, featuring the 598 cc air-cooled two-cylinder OHV engine from the Prinz III, which delivered 30 PS (22 kW) at 5,500 rpm. This model marked a significant step in practicality by introducing a four-door body option alongside the two-door variant, while preserving the for compact maneuverability. The body featured a wraparound rear window for enhanced visibility and aesthetics reminiscent of the , with an overall length of 3,440 mm. The chassis retained independent front suspension, contributing to agile handling despite the rear-engine configuration. Performance with the two-cylinder achieved a top speed of 118 km/h, 0-100 km/h in 28 seconds, and combined fuel economy of 7 L/100 km, making it suitable for everyday family use on European roads. From 1967, an optional three-speed was available, broadening appeal to drivers seeking ease of use, while safety features were updated with a padded to reduce injury risk in minor collisions. Positioned as a versatile family , the Prinz 4 emphasized reliability and low running costs, with 576,619 units produced from 1961 to 1973.

Prinz 1000, TT, and TTS

The NSU Prinz 1000, introduced at the 1963 Motor Show, marked a significant step up in the four-cylinder lineup with its 995 cc air-cooled overhead-camshaft inline-four engine producing 50 hp (PS), paired to a rear-wheel-drive layout in a compact two-door sedan body. This model evolved the platform from the earlier Prinz 4 by extending the to 2,250 mm and overall length to 3,793 mm, while maintaining a weight of approximately 800 kg to enhance agility. Aerodynamic refinements, such as a smoother roofline and integrated chrome trim, contributed to its sporty aesthetic, complemented by optional sport seats for improved driver support during enthusiastic driving. The TT variant, launched in as the Prinz 1000 TT (Typ 67b), introduced performance-oriented tuning with a twin-carburetor setup on its initial 1,085 cc delivering 55 hp (DIN), later upgraded in 1967 to the 1,177 cc version in the renamed 1200 TT (Typ 67c) producing 65 hp (DIN). This configuration enabled a top speed of 153 km/h and 0-100 km/h in 13 seconds, bolstered by standard front disc brakes that provided superior stopping power and handling compared to the setups of base models. A fully synchromesh four-speed improved shift precision and drivability, allowing smoother gear changes under load and contributing to the car's nimble rear-engine dynamics. Available in both sedan and coupe-like two-door configurations, the TT emphasized its sporting intent through dual oval headlights and a lowered stance, with production totaling 14,292 units of the 1000 TT from to 1967 and 49,327 of the 1200 TT through 1972. The TTS special edition, produced from 1967 to 1971, represented the pinnacle of the series with its 1,177 engine tuned to 70 hp (DIN) via dual Solex carburetors and an integrated oil cooler for sustained high-rev performance. Limited to 2,402 units to meet requirements for Group 2 , the TTS featured reinforced chassis elements, sport-tuned suspension, and the same disc brakes and synchromesh gearbox as the TT, all in a 700 kg two-door sedan body optimized for track use. Its racing pedigree shone in events like the 1967 , where NSU factory and entries competed in the under-1,000 class, demonstrating reliability over distances. These models collectively showcased NSU's focus on lightweight, rear-engined sportiness, bridging everyday usability with competitive edge until production ended in 1972.

Production and Legacy

Manufacturing and Sales

The NSU Prinz series was manufactured exclusively at the company's plant in , where assembly lines adapted from NSU's extensive production expertise enabled efficient output of the rear-engined small cars. Leveraging techniques honed in high-volume manufacturing, the facility scaled up to produce over 1 million units across all variants from 1958 to 1973, with annual production peaking at approximately 130,000 vehicles in 1968. Sales were predominantly domestic, with around 80% of output absorbed by the German market, where the Prinz's affordable pricing—starting at about 4,700 Deutsche Marks for base models like the Prinz 4 and reaching up to 8,500 DM for sportier variants such as the 1000 TTS—helped it compete as an economical city car. Exports focused on , bolstering NSU's regional presence, while shipments to the totaled fewer than 10,000 units, peaking at roughly 3,000 annually in the early 1960s before discontinuation in 1969 due to stringent emissions regulations that the air-cooled engines struggled to meet. The Prinz line played a pivotal economic for NSU, generating substantial that funded ambitious projects like the innovative Ro 80 rotary-engined sedan launched in 1967. However, intensifying competition from established rivals such as the and eroded market share, while reliability concerns—including engine overheating in the air-cooled units—resulted in elevated warranty claims and service costs, straining the company's resources amid the small-car segment's saturation.

International Production and End of Line

The NSU Prinz saw limited in several international markets, adapting its compact to local needs. In , Autoar assembled the Prinz II and III models starting in 1959, marking an early effort to localize manufacturing in . Production continued until 1963, with the vehicles tailored for regional roads and preferences. In , the Prinz served as the basis for the Ramses, Egypt's first domestically produced automobile, assembled by the Nasr Automotive Manufacturing Company from 1960 onward. Named after the ancient , the Ramses II variant used NSU-supplied drivetrains and mechanical components, with local fabrication of body panels near the Great Pyramids, symbolizing national industrialization under President Nasser. Initial output was modest, at three to four units per day, with total production across variants estimated at under 1,700 units before cessation in 1966 due to economic challenges and supply issues. Uruguay represented another outpost for Prinz assembly, where S.A. began producing the model in 1963 using NSU-supplied kits for the Prinz 4 and Sport Prinz, aiding the launch of the country's nascent auto industry. Later, from 1969 to 1971, the importer Quintanar developed variants like the P6 and P10, featuring elongated bodies and the larger 1.0-liter engine from the Prinz 1000, with approximately 500 units built before NSU withdrew from the market. The Group's acquisition of NSU in 1969, prompted by the latter's financial strains from development, marked the beginning of the end for the Prinz lineup. Integrated into , the small rear-engine models were gradually phased out as VW prioritized front-engine, water-cooled designs aligned with its portfolio, including the upcoming (badged as ).
