Aerodynamics is a vehicle editor mode used for setting the vehicle's lift and drag coefficients for the body, rear wing, front wing, and undertray.

1. 1 Open the vehicle editor.
2. 2 Click the Aerodynamics button in the top left corner.

State

Each aero element can be in one of three states:

• in use : the aero element is active
• not useduse : the aero element is not active, click use to enable it
• not usable : the aero element is not available

By default, only the body element is available (it is also the only one that cannot be disabled). To use any of the other elements, you must add the corresponding subobject in the modeller. The placement of the subobject determines the position where the aerodynamic force is applied. To set the position of the force applied to the body, you can add an aero centre subobject.

Aerodynamic coefficients

Each aero element has three coefficients you can set:

• Max lift: the upward force applied; wings and undertray use negative values for downforce. Setting the lift to zero disables the element.
• Max drag: the force applied opposite to the vehicle's velocity vector, slowing it down.
• Side drag: same as Max drag, but only applies when the relative airspeed has a lateral component (e.g. when the car is oversteering, or with wind from the side).

The total lift/downforce and drag forces are calculated from the car's speed, direction of movement, and wind.

The rear wing and front wing have additional parameters to allow adjusting their downforce:

• extra: a set angle, always added to the setup angle
• min: the minimum angle in the adjustable range
• max: the maximum angle in the adjustable range

For instance, for an extra value of 10, a minimum of 5, and a maximum of 20, the adjustable range will be 5-20, and the effective angles will be 15-30.

You can refer to the setup's Downforce tab to check the total lift and drag for each element at any given speed.
