42140

LEGO Technic set 42140, App-Controlled Transformation Vehicle, is an app-controlled transforming vehicle in the Technic theme. Released in 2022, it contains 772 pieces and includes no minifigures, with the focus placed on mechanical action and vehicle behaviour.

Set 42140 belongs to LEGO Technic, a theme built around structural building, movement and functional mechanisms. Its subject is not a fixed-shape vehicle, but a transforming vehicle whose identity is tied to change during use. That places it among Technic models where the function is as important as the finished form.

The set contains 772 pieces and no minifigures. The build therefore concentrates on the vehicle itself, including the frame, moving sections and body elements needed to express the transformation concept. With no named characters or separate scene elements listed, the model’s technical behaviour remains the centre of attention.

This set is aimed at builders who want a Technic model to operate and test, as well as to display. In a collection, it fits with functional Technic vehicles rather than purely static display builds. Its app-controlled transforming concept makes it useful for comparing how different Technic sets handle motion, control and play value within the same theme.
