Tesla patents active ground-effect floor to boost EV downforce

U.S. company Tesla has patented an innovative aerodynamic system designed to markedly increase downforce and sharpen the dynamics of its electric cars. The concept, inspired by Formula 1 technology and aimed at improving road grip, was reported by journalists at Tarantas News.

How Tesla’s active “floor” works

According to the patent, the system uses movable skirts and central fans to create a low-pressure zone beneath the vehicle. At low speeds, the fans operate at maximum output, pushing air rearward to generate a vacuum-like effect. As a result, the car presses itself to the road surface, including during launches from a standstill.

Technical features and adaptation

At higher speeds, the system shifts into an adaptive mode. Its electronics adjust skirt position and fan intensity based on speed, road gradient, available grip, and GPS data. This approach makes downforce controllable and predictable across different scenarios, including starts, acceleration, and maneuvers.

In essence, Tesla is reinterpreting the ground-effect principle that Lotus and Brabham used in late-1970s Formula 1. Those solutions delivered exceptional traction but were banned due to associated risks. Should Tesla take this system to series production, the brand’s EVs could reach downforce levels previously seen only on racing prototypes. The idea reads as a pragmatic nod to race-bred know-how: finely metered downforce where it matters promises crisper responses and added confidence without overcomplicating the driver’s experience.
