A complete hydraulic clutch in real parts: pedal box, master and slave cylinders, release bearing, pressure plate, disc and flywheel.
Press the pedal and watch the diaphragm spring flex and the disc stop while the flywheel keeps turning, then let it up slowly through the bite point.
Start the engine and find the bite point yourself.
Lift out any of the clutch’s nine sub-assemblies and tear it down stage by stage.
New build steps and quiz questions for the clutch.
Version 2.5
A new look, and rebuilt brakes and drivetrain
New app icon, welcome screen and home screen.
Brakes: a complete front brake corner in real parts. Run the brake test, wear the pads down and tear it down stage by stage.
Drivetrain: the CV axle, both joints and the open differential. Drive it, steer it and strip it down.
Suspension fixes and polish.
Version 2.4.2
Fixes and performance
Bug fixes and performance improvements.
Version 2.4
A new engine, modelled part by part
The engine is rebuilt as a four-stroke inline-four with a cutaway first cylinder and every part live.
Version 2.3
Suspension, rebuilt
The MacPherson strut corner is now a fully modelled assembly: a real tyre with tread and sidewall texture, a cast-alloy knuckle, a forged control arm, the anti-roll bar, the drop link and the drive axle.
Every part is tappable, with its own spec sheet. A new strut tower part shows where the strut bolts into the body.
The bump test, the exploded view and Build mode all run on the new model, and taps land on exactly the part you touch.
