Porsche Exhaust Muffler Doubles as Diffuser

Porsche has recently filed a patent to protect a unique and innovative idea for their cars. The patent, discovered by CarBuzz at the German Patent and Trade Mark Office, involves using the exhaust muffler of a car, such as the Porsche 911, as a rear diffuser that also enhances aerodynamics. This idea could potentially be put into production once the necessary tooling is developed.

The patent describes the invention as a "rear silencer in an exhaust system, the underside of which is aerodynamically shaped and can be equipped with air-guiding elements." This means that the exhaust system would not only serve its traditional purpose but also contribute to the car's overall aerodynamic performance.

According to an article by ScienceDirect, the placement of an exhaust exit can indeed have an impact on a car's aerodynamic properties. However, the effects of this placement are relatively minor compared to the benefits provided by an aerodynamically sculpted underbody. This suggests that the new idea proposed by Porsche could have significant advantages in terms of improving the car's overall aerodynamic efficiency.
