Heidelberg Historic 2017

From June 13 to 15, lovers of beautiful vehicles can get excited about two anniversary vehicles from the Audi Tradition collection as the NSU TTS and the NSU Ro 80 will both be celebrating their 50th birthday in Heidelberg.

50 years of the NSU TTS

At the Hockenheimring in February 1967, NSU presented a compact sports car for the Group 2 Touring Car Class. The body of the TTS was the same as that of the NSU 1000. Ensuring powerful delivery of drive power was a 996 cc air-cooled four-cylinder engine with a maximum output of 70 hp at 6,150 rpm. Depending on the axle ratio, the TTS, which weighed around 700 kilograms (1,543.2 lb), could reach 165 km/h (102.5 mph) and sprinted from 0 to 100 km/h (62.1 mph) in 11.8 seconds.

"Speed kit" for use in racing

With the addition of the racing "speed kit" available directly from the factory, the TTS engine was capable of 85 hp at 6,600 rpm. A downpipe exhaust system, open air funnels, modified adjustment of the carburettors, a new ignition distributor and type 310 racing spark plugs all made it possible to increase output by 20 percent. NSU also supplied various stepped transmissions. By the end of October 1971, a total of 2,402 NSU TTS vehicles had been produced.

The TTS will have prominent company by its side at Heidelberg Historic: the NSU Ro 80 with its two-disc Wankel engine which also premiered 50 years ago. Thanks to its futuristic, wedge-shaped body line, it became a milestone in automobile design.
