Chassis and gearbox corresponded to those of Prinz III. Speculation for the first use of the Wankel engine was not fulfilled.The conventional engine now made 30 hp (22 kW) from 598 cc. This allowed a top speed of 116 km / h. The Prinz 4 weighed only 570 kg and had a maximum permissible weight of 1000 kg.with this layout the distribution of weight was 44% to front axle,and 56% at the rear axle.

The rarely purchased "Prinz 4" was the simple version (corresponding to the earlier Prinz I), while the "Prinz 4S" represented the normal version (corresponding to the earlier models Prinz II and III). These two versions were offered unchanged until March 1969.
From September 1965 came the version "Prinz 4L" with again improved equipment and sunshine roof option, which was built almost unchanged until April 1973. There were only minor changes, such as the front panel molding. Front disc brakes was now a option.
The vast majority of vehicles from the last years of production were sold to Italy, in the years 1968-1970 these were 123,338 of 170,080 manufactured copies, ie 72.5%. In total, about 570,000 NSU Prinz 4, Prinz 4S and Prinz 4L were created in twelve years.
In Egyptian Cairo, the NSU Prinz 4 was assembled for the local market by the Egyptian Light Transport Manufacturing Company as Ramses II . In Montevideo This rolled off the line at Nordex SA as P-1000 .The Prinz 4 is considered a stylistic model of the Soviet SAS-966 "Saporoshez" , which was built in 1966.
