Fields
| Field | Type | Required | Default | Allowed values | Description |
|---|---|---|---|---|---|
dragArea | number | no | Frontal reference area in square metres, zero or more. Drag is 0.5 * 1.225 * frontalCd * dragArea * v², with v in m/s. A saloon is about 2.2 m², a van about 3.5 m². | ||
frontalCd | number | no | Drag coefficient, dimensionless and zero or more. About 0.30 for a modern saloon, 0.35 for an SUV, 0.40 and up for a boxy van. Zero on either this or dragArea turns drag off, which is what an arcade vehicle usually wants. | ||
downforceFront | number | no | Downforce coefficient for the front axle in N·s²/m², zero or more: the downward force in newtons is this times v², with v in m/s. 0 is a road car, which makes none worth modelling. | ||
downforceRear | number | no | The same for the rear axle, in N·s²/m². 0 is a road car. |
