A USPTO patent filing reveals a two-piece active rear wing for the Tesla Roadster that shifts between low drag, high downforce, and crash-safety positions. The system is designed to generate significant downforce while remaining flush with the vehicle body when retracted. This technical detail emerges ahead of the upcoming Roadster debut.
The patent filing serves as a technical preview for the Roadster's aerodynamic capabilities, distinguishing it from standard fixed spoilers by introducing an active, multi-position system. The emphasis on crash-safety retraction highlights a design philosophy that integrates performance with passive safety, a detail that bridges the gap between high-performance engineering and consumer vehicle standards.

The focus is on the quantitative aerodynamic capability, highlighting the specific downforce figure and the 'wild' design of the active wing.
The detailed mechanical linkage structure is described less technically than in other sources.
The coverage details the multi-section hinge linkage mechanism and explains the specific operational modes (flush, high downforce, low drag) and their functions.
The specific downforce number is not highlighted as prominently as the mechanical description.
