3D Mechanic: How Cars Work

Seven real car systems in interactive 3D. Orbit, explode, tap any part, run the animation — then rebuild it yourself and prove it in the quiz.

Ever wondered what actually happens when you press the brake pedal, turn the wheel, or let out the clutch? 3D Mechanic puts real automotive assemblies in your hands — not diagrams, but full 3D hardware you can orbit, pull apart, and rebuild.

SEVEN REAL SYSTEMS • Suspension — MacPherson strut (free) • Wishbone — double A-arm suspension • Brakes — floating disc caliper • Steering — rack & pinion • Drivetrain — CV axle & joints • Engine — inside the four-stroke inline-four • Clutch — clutch & flywheel

LEARN Orbit each assembly, explode it apart, and tap any of 70+ real parts for what it does, how it fails, a pro tip, and a workshop spec sheet. Run the live animation — the bump test, brake clamp, steering sweep, four-stroke cycle, pedal press — and watch every part move the way it does on a real car. Take the guided tour or toggle a translucent car body to see where the assembly lives.

BUILD Every part starts scattered on the shop floor. Drag each one home in true workshop order — the app knows what installs next, snaps parts into place, and calls out mistakes just like a mentor would.

QUIZ Two quiz types per system: identify parts on the 3D model, and put the assembly in the correct installation order. Best scores are saved so you can watch yourself improve.

Built for learners, new technicians, car enthusiasts, and anyone who wants to understand the machine they drive every day.

ONE PURCHASE, EVERYTHING Suspension is free. A single one-time Full Garage purchase unlocks all seven systems and every future module. No subscription, no ads, no tracking, no account — and everything works offline. Family Sharing supported.
