It's a closely fought contest. The 1967 NSU TT TTS brings quicker acceleration, lighter weight, greater rarity to the table, and the 1970 NSU Ro 80 Sedan answers with more power, higher top speed, stronger collectibility. Both are excellent machines that reward their owners in different ways — there's no wrong answer here.
NSU has long offered a diverse lineup, and comparing the 1967 NSU TT TTS with the 1970 NSU Ro 80 Sedan highlights the breadth of the marque's engineering philosophy. The 1970 NSU Ro 80 Sedan holds a clear advantage in raw power with 115 hp compared to 70 hp, a 45-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the NSU TT uses a Inline-4 OHC displacing 1,177 cc, while the NSU Ro 80 relies on a Wankel Twin-Rotor with 995 cc. In the sprint to 60 mph, the 1967 NSU TT TTS edges ahead at 11.0 seconds versus 12.8 seconds. The NSU TT carries a weight advantage, tipping the scales 1037 lbs lighter. Rarity plays a significant role here — with only 2,400 units built, the 1967 NSU TT TTS is considerably scarcer than the NSU Ro 80's 37,398 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
