## Fields

| Field | Type | Required | Default | Allowed values | Description |
|---|---|---|---|---|---|
| `torqueCurve` | `VehicleTorquePoint[]` | no |  |  | Crankshaft torque against engine speed, as [rpm, N·m] points, non-empty and strictly increasing in rpm. Linearly interpolated, clamped outside the range. An override REPLACES this array whole; there is no element-wise merge. |
| `idleRpm` | `number` | no |  |  | Engine speed the solver holds at with no throttle and the clutch open, in rpm. Greater than zero and less than redlineRpm. |
| `redlineRpm` | `number` | no |  |  | Engine speed at which torque is cut and an automatic gearbox shifts up, in rpm. Greater than idleRpm. |
| `inertia` | `number` | no |  |  | Rotating inertia of the crankshaft and flywheel in kg·m², greater than zero. It sets how fast the engine picks up when the clutch is open — small is a revvy engine, large is a diesel that takes its time. |
