3D Mechanic: How Cars Work app analytics for October 23

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. EIGHT REAL SYSTEMS • Suspension — MacPherson strut (free) • Wishbone — double A-arm suspension • Brakes — floating caliper corner with ABS • Steering — rack & pinion with electric power assist (66 parts) • Drivetrain — CV axle, joints & open differential (71 parts) • Engine — inside the four-stroke inline-four • Clutch — pedal to flywheel, hydraulics and all (62 parts) • Gearbox — five-speed manual, synchros and all (77 parts) LEARN Orbit each assembly, explode it apart, and tap any of 500+ 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 test, steering sweep, four-stroke cycle, pedal press, gear shift — 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 The MacPherson strut suspension is free. A single one-time Full Garage purchase unlocks all eight systems and every future module. No subscription, no ads, no tracking, no account — and everything works offline. Family Sharing supported.
