Mini-spy
From MediaWiki

Mini-spies were very small Transformers toys that came packaged with Mini Vehicles in early 1985. Mini-spies were the first toys to feature rubsigns, and the only way to determine whether a given Mini-spy toy was an Autobot or Decepticon was by rubbing the rubsign.
There were four different Mini-spy molds, known by the unofficial names 4WD Type, Buggy Type, Mazda Type, and Porsche Type, and each was available in blue, white and yellow variations.
The pre-Transformer versions of the Mini-spies were part of a toyline called Mecha Warriors, and came in blue and red variations. [1]
