Procedural 3D geometry
Block, head and crank modelled from spec. One cylinder to V12, plus the weird stuff.
Build it, tune it, rev it. Rigid-body physics down to the crank degree, on Mac, iPhone and iPad.
Block, head and crank modelled from spec. One cylinder to V12, plus the weird stuff.
Eleven sections of real engineering knobs. Set them once and the engine derives the rest.
Brush ignition and fuel cells across load by RPM. Cells flood red when you push past safe.
Real torque and power curves with peak callouts. Tune, run, retune until it pulls clean.
Live wireframe scan. Real fault codes. Break it, then one tap to repair.
Describe the engine you want. The model drafts the full spec, ready to fine-tune.










A native Mac, iPhone and iPad app, built for Apple Silicon. The entire engine simulation runs in real time, right on your device.
Native on every M‑series Mac, plus A‑series iPhone and iPad. The chips shown are a sample of the lineup.
The same simulator, the same physics, tuned for touch.
