In 1986, LEGO introduced a theme named Model Team. This theme included the vehicle model with a larger scale and with more details, such as turning function. Theme focused on visual realism of models. The logo of Model Team had changed three times in 1990, 1992 and 1999. The set number starts with a 55XX prefix for a regular set. One promotional set, 2556, was released in 1997 featuring Shell and Ferrari. Model Team was discontinued after 1999. In 2004, the Model Team set 5541 was re-released as 10151 in the Legends theme.
