The starting point is the Prinz 1000 L of 1964. The comes far less than 700 kg and thus has besides a for the shape still good top speed of 135 km/h, one for the time anything but small cars similar acceleration. This will be transferred to its much more powerful successors, what these makes almost unbeatable for example at the slalom.
It is very atypical that the displacement in the TT grows to 1100 cc and later even more but in the TTS is taken back again. Sure that has regulations reasons but also based on the fact that just the one liter incredibly accelerates. In addition there is an always already more progressive suspension towards the swing axles and rigid axles competition. Result: The closer the course, the more superior this NSU.
The civilian versions of NSU can not compete with its air-cooled rear engine, for example against the Opel Kadett, but rather the sporty. Then there is the considerable number of tuners to elicit the engine additional horsepower. Inspiring how the driver of a TTS at full acceleration from zero the engine power brings on the ground with semi-rotating tyres. Here one can really see how much slip is just allowed to achieve the best result.
The TTS also transforms the inherent disadvantages of the standard version such as the wheelbase is too low and the rather harsh suspension in benefits for racing. However, the greater the circuit and thus the race distance the more other drawbacks come to light, e.g. the not so good directional stability, the need constant correction on long and fast straights, depending on road conditions. Nevertheless, it won the 24-hour race in its class at the Nurburgring.
Furthermore the rear engine's own sensitivity to cross winds. And the oversteering driving behaviour may well be very favorable for the slalom but not for very fast curves or wavy pavement. And for everyday life and the torque are always better the 48 kW (65 hp) of the later TT with 1200 cm³ than the 51 kw (70 hp) from 1,000 cm³ version of the TTS. It is designed from the start of as a racing machine. 07/11
