Build a Car

About Build a Car

Build a Car puts you in charge of designing your own vehicle from scratch, then sending it out to tackle obstacle-filled tracks. Every build starts with a blank grid and a selection of components — engines, wheels, and other parts — that you combine to create a machine capable of handling whatever the levels throw at it. Each part directly shapes how the car behaves, affecting power, stability, and off-road capability, so the choices you make at the workbench carry real weight on the track.

Several scenes show block-based trees with green and white canopies and brown rectangular trunks dotting the environment. A blue sky with stylized white clouds appears in the background across multiple views. The primary terrain surfaces are made up of bright green, red, and blue blocks with circular studs on top.

The game sits in the simulation and physics space, with 3D construction and driving at its core. Experiment with different designs, buy new components, and keep refining your vehicle as the tracks grow tougher.

How to Play Build a Car: Build, Drive, and Complete Every Level

The loop in Build a Car moves between two distinct phases: construction and driving. In the building phase, you place parts onto a grid to assemble your vehicle, then confirm each placement. Once you're satisfied with the design, you take it out onto obstacle-filled tracks and see how far it can go. The better the build, the farther you'll reach.
