NSU Prinz - NSU Prinz 4

One of the revelations of the Frankfurt Motor Show in September 1961, 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 tradition of eccentric rod driven camshaft inherited from NSU motorcycle engines and interestingly had a dynastart (combined starter/generator) built into the crankcase. 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. The test car achieved a top speed of 113 km/h (70 mph) and accelerated to 97 km/h (60 mph) in 35.7 seconds. The home grown Mini 850 reached 97 km/h (60 mph) in 29.5 seconds in an equivalent recent test and also managed to beat the NSU's top speed, albeit only by about 3%. 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) £561 asked for the 850 cc Mini, but certainly not completely out of touch with it. The testers concluded their report that the car was competitively priced in its class and performed adequately. They opined, cautiously, it offered 'no more than the rest' but neither did it 'lack anything important'.
