Rear Wing Profiles Reference Volume (RV-RW-PROFILES)

Chapter: C

In Simple Terms

This regulation defines the maximum allowable space (or 'reference volume') where a Formula 1 car's rear wing can be positioned and shaped. Think of it as an invisible 3D box that the rear wing must fit within, with one angled plane cutting through it to set the upper boundary. If a team's rear wing extends beyond this box, it violates the rules.

The rear wing must fit within a defined rectangular box measuring 465mm long (X-axis), 575mm wide (Y-axis), and 155mm tall (Z-axis)
An additional angled plane cuts through this box, removing the upper portion and creating a sloped upper limit for the wing profile
This volumetric restriction ensures all cars have comparable rear wing dimensions and prevents unfair aerodynamic advantages
Teams must design their rear wing profiles to stay entirely within this reference volume during technical scrutineering

Official FIA Text

RV-RW-PROFILES is an axis-aligned cuboid [XR=165, 0, 725] to [XR=630, 575, 880], trimmed with plane passing through three points with all material below discarded.

Tail Bodywork to Floor and Upper Bodywork Assembly

Chapter: C3

In Simple Terms

F1 cars must have their rear wing and bodywork pieces fit together neatly with no gaps. Teams can use slightly rounded edges (up to 25mm curves) where different bodywork sections meet, but everything must be properly aligned and trimmed to fit precisely.

Tail bodywork and upper bodywork must be properly fitted together with no gaps or misalignment
Maximum fillet radius of 25mm allowed at intersections where different bodywork volumes meet
This rule ensures aerodynamic consistency and prevents teams from exploiting gaps between bodywork sections
All edges and intersections must be neatly trimmed and finished

Official FIA Text

Tail and Upper Bodywork to Floor Assembly must be trimmed to each other. Fillet Radius no greater than 25mm may be applied along intersections between volumes.
