Blown Diffuser

A Blown Diffuser is an aerodynamic device used in motorsport that directs exhaust gases into the diffuser area at the rear of the car to generate additional downforce.

This system works by channeling high-energy exhaust flow to enhance the diffuser's performance, creating a stronger low-pressure zone beneath the car. What made blown diffusers particularly effective was their ability to maintain downforce even when drivers weren't on the throttle, improving stability during braking and cornering.

Blown diffusers reached their peak in Formula 1 during the early 2010s, with Red Bull Racing pioneering advanced versions of this technology. The considerable performance advantages led to increasingly complex systems before regulatory changes effectively banned them from competition.
