Holy crap! I've owned numerous NSU's over the years including a couple ro80's and had no idea this car even existed. The transmission was actually a standard 3- or 4-speed, but with a shift lever-actuated electric clutch, similar to Porsche's Sportomatic. It also came standard with inboard disc brakes and numerous other ahead-of-its-time innovations that made the ro80 an amazing road car. Unfortunately, like many early rotaries, insufficient apex seal lubrication led to its demise.
