About Dream Car Builder
Dream Car Builder lets you construct vehicles from individual beams that behave under a realistic soft‑body physics engine. Every component can stretch or compress, so designs must consider structural stress before racing.
The game offers a single‑player mode with procedurally generated tracks, a sandbox environment for unrestricted building, and online PvP. Creations can be shared through Steam Workshop, and the title runs on Windows with partial controller support.
01 / THE GUIDE
Car Editor
The car editor provides a workspace where you place beams to form chassis, steering, and other parts. Because the physics treats each beam as a deformable element, the vehicle reacts to forces rather than snapping into a preset shape.
Design choices such as beam length and angle directly affect handling and durability. The editor does not auto‑assemble parts; you must arrange each element to achieve a functional car.
- Start with a simple rectangular frame to observe basic beam behavior.
- Adjust beam angles in small steps and test before adding more complexity.

Single‑Player Races
In single‑player mode the game generates tracks algorithmically, delivering a new layout for each race. These procedurally generated courses test the strength and handling of your custom car without needing external content.
Because each run uses a freshly generated track, you can evaluate how design changes perform across varied terrain and obstacles, helping you refine your vehicle iteratively.
- Observe the early sections of a track to anticipate upcoming turns.
- After each race, tweak wheel placement to see its effect on cornering.

03 / THE GUIDE
Sandbox Mode
Sandbox mode lets you build cars without preset limits on component count. This open environment encourages experimentation with complex structures while the same physics model applies as in races.
You can test structural integrity, watch deformation in slow motion, and iterate rapidly, making sandbox a practical space for learning how beams respond to stress.
- Use sandbox to trial designs that might be risky in a timed race.
- Save multiple versions of a build to compare how small changes affect deformation.
04 / THE GUIDE
Soft‑Body Physics
The game implements 100 % realistic soft‑body physics, meaning every beam can stretch or compress under load. This model creates visible deformation when forces act on the car.
A built‑in slow‑motion feature lets you slow down time to examine how specific sections react, providing insight into stress points that may need reinforcement.
- Activate slow motion during high‑speed turns to spot weak spots.
- Reinforce areas that show excessive compression in your tests.

User‑Generated Content
Through Steam Workshop, players can upload and download vehicles, tracks, and maps. This community content expands the variety of designs and courses beyond what the game generates internally.
Downloading creations offers practical examples of effective engineering, while sharing your own builds invites feedback from other users.
- Search the workshop for highly rated tracks before building your own.
- Provide clear descriptions when uploading to help others understand your design.
