This aptly named "piston car" was released in 1999 came in multiple packages with different numbers as part of a series of 4 micro models. As 1260 it came in standard Technic packaging in a small box. As 3005 it was available as a polybag only in Japan with Kabaya candy. There is no difference apart from the packaging.
This is a particularly unconvincing model as it does not really look like anything recognizable. However, for all its lack of realism it does sport a truly massive single cylinder engine which, to scale, must have a bore of close to a meter.
This model has a single cylinder reciprocating engine. The crankshaft is also used as a solid rear axle giving a permanent 1:1 gear ratio.
The animation shows the raw power of this engine as the model does a smoky burnout and is clearly just itching to start a race.
