# Aerodynamics

Active front surfaces, barge boards, a hood vent, and a three-position rear wing.

## Front

Engineers describe the front as a five-surface wing whose leading edges can tilt up to 80 degrees. Panels behind the front wheels pop out as barge boards, which are also said to cool the carbon-ceramic brakes. An active vent sits in the hood.

## Rear wing

The rear wing is described in road, high-downforce, and low-drag positions. Optimus-derived actuators move it, with a holding brake. It can tilt about 90 degrees as an airbrake, and the charge port is hidden behind it.

At speed, the aero package is described as making up to 2 g of downforce.

## Not yet published by Tesla

The wing positions and the 80-degree leading edges come from engineer interviews, not from a Tesla spec sheet with measured downforce.
