The SS was the quickest kei-car yet, managing to break the twenty second barrier in reaching 400 metres from standing with 19.95 seconds. The car had different wheels and also featured a rev counter. It was introduced with an unusual marketing stunt: racing driver Stirling Moss and TT-winning motorcycle racer Mitsuo Itoh were engaged to drive two SS Frontes (one red, one pale yellow) on a high-speed demonstration journey along Italy's "Autostrada del Sole" leading from Milan to Napoli.
