Part III of this Rare Rides series explored how NSU readied itself to re-enter the car market and end its longstanding production tie-up with Fiat. Shortly after the painful divorce from the Italians, NSU’s first rotary-powered car was ready.
The very first Western-produced car powered by a Wankel, the tiny NSU featured a single rotor. At 498cc in displacement, the engine resided at the back, beneath the rear luggage compartment. There was also a luggage compartment under the hood at the front, though storage was limited as the entire car was just 141 inches long.
A curb weight of 1,500 pounds matched well with the claimed output of 50 raging horsepower. All that power was sent through the rear wheels via a four-speed manual. 0-60 acceleration time was a claimed 15.7 seconds. The Spider was available in either red, or white.
A low-volume roadster, in the U.S. the NSU asked a hefty $2,979 in 1964. The model continued for four years, and at its conclusion in 1967 there were 2,375 scattered about the world. At that time, NSU cancelled its old Prinz-based rotary models, as its new flagship rotary sedan, the Ro 80, was ready for sale (Rare Ride for another day).
The development of rotary engines had drained the company’s coffers, and the technology was not paying dividends quite as management had expected. Engineers were having problems too, as the apex seals of NSU rotaries were prone to failure. After the Spider’s introduction, NSU added various rotary designs to the rest of its lineup — all of which had problems. This led to a loss of consumer confidence in the brand.
Facing debt and image issues, the company was forced to sell out to Volkswagen. The transaction was completed in 1969, and NSU was immediately folded into the Auto Union. The new company was known as Audi NSU Auto Union AG, and all newly developed NSU vehicles and their respective branding switched over to Audi.
NSU’s phased out its smaller vehicle offerings during the 1973 model year, though the flagship Ro 80 model continued until 1977. The combined company continued as-is, with management based in NSU’s Neckarsulm plant until 1985. It was then that the final pieces of NSU disappeared; the company was renamed Audi AG. All management at Neckarsulm moved to Audi’s headquarters in Ingolstadt, where the brand remains today.
The car which generated this long Rare Rides history is a 1965 Spider, for sale outside of Chicago. With 13,000 miles on the clock, it needs some attention (and a windshield) from a new owner. The seller wants $17,699, but how many other rear-engine, single rotary roadsters are out there?
