New: courses, and a car on the home screen. • Courses for seven systems, part of the Full Garage: five lessons on how each one works, then two workshop jobs, such as changing the front pads or bleeding the clutch. • Each job goes step by step: pick the next part, the tool, its size and the torque. Do it guided first, then on your own for stars. • An x-ray car on the home screen: tap a dot on it to open that system. • The courses are on the home screen too, with a Continue card for the one you've started. Founding price until October 30: after that, the Full Garage price goes up. One purchase unlocks every system, including every future one.
3D Mechanic shows how a car works through eight systems you can take apart and put back together in 3D. The engine alone has 256 parts, cut open so you can watch it run. THE SYSTEMS • Suspension: MacPherson strut, free (104 parts) • Wishbone: double A-arm suspension (112 parts) • Brakes: floating caliper corner with ABS (50 parts) • Steering: rack and pinion with electric power assist (66 parts) • Drivetrain: CV axle, joints and open differential (71 parts) • Engine: 2.0 L twin-cam inline-four, cut open through cylinder 1 (256 parts) • Clutch: hydraulic, from the pedal to the flywheel (62 parts) • Gearbox: five-speed manual with synchros (77 parts) LEARN Start from the x-ray car on the home screen: tap a dot to open that system. There are nearly 800 parts: tap any one to see what it does, how it fails, a pro tip and its spec sheet. Run the animations: the bump test, the brake test, steering lock to lock, the four-stroke cycle, a clutch pedal press and a gear shift. The guided tour goes through every part in order, and a see-through car body shows where the system sits. COURSES Seven systems have a course: five lessons on how the system works, then two workshop jobs, such as changing the front pads or replacing a driveshaft. Each job goes step by step: pick the next part, the tool, its size and the torque. Do it guided first, then on your own for stars. BUILD Drag the parts from the workshop floor back onto the assembly, in the order a mechanic would fit them. Try one too early and it goes back to the floor: something else goes on first. QUIZ Three quizzes per system: name the parts on the model, put them in installation order, and answer workshop questions on torque specs and teardown order. Your best score is kept. THE FULL GARAGE The MacPherson strut is free. One purchase unlocks the other seven systems, the seven courses and every new system as it ships. No ads, no tracking and no account, and it all works offline. Family Sharing is supported.
