Description

Built around function, not figures

Like most LEGO® Technic sets, the Transformation Vehicle skips minifigures entirely. The build centres on mechanics instead: app control, moving parts and the ability to switch shape are the whole point of the set, not character-driven storytelling. That is a clear draw for fans of functional models, though it is worth knowing upfront if minifigures are what you are after. Anyone who already owns other Technic vehicles will recognise this focus on mechanics over figures, since it runs through almost the entire product line rather than being unique to this set.

772 pieces, 113 part types

With 772 pieces made from just 113 unique elements, the ratio is typical for Technic: plenty of repeated connectors and structural beams, alongside specialised parts such as axles, gears and electronic components that form the technical core. The building experience leans structural rather than visually varied step by step, prioritising function over surface detail. Builders familiar with other Technic sets will recognise many of the basic connector pieces, while the electronics and drivetrain components here are more specific to this particular model.

A sporty black-and-blue finish

Black and blue make up the bodywork, with light and dark bluish grey covering the chassis and structural elements inside the model. That combination is common on sportier Technic vehicles and gives the model a clean, technical look that matches its identity as a functional build rather than a toy car. Unlike brightly coloured play vehicles, the palette here stays deliberately restrained so the mechanical details stand out instead of competing with the colour scheme. The exact colour breakdown, part by part, is available in the parts list on this page.

Reusable Technic parts

Once the original build is complete, the 113 distinct elements are also useful for other Technic projects, such as chassis work or mechanical detailing on different vehicles. The parts list on this page shows exactly which technical elements are included, in what colour and quantity, which helps when hunting for a specific piece for a new build. Axles, connectors and gears in particular combine well with parts from other Technic sets, letting a collection of functional components grow across several builds over time.
