BMW Registers Patent For Internal Fan That Adjusts Motorcycle Aerodynamics In Real Time To Improve Grip In Corners And Braking
BMW surprised the automotive sector by registering a new patent that proposes the use of an internal fan to improve the grip of motorcycles. It involves an active aerodynamics system that channels pressurized air through ducts and nozzles strategically positioned on the motorcycle’s body.
The most important thing is that the project aims to alter the dynamic behavior of the machine even at low speeds.
Unlike the traditional wings of MotoGP or the fixed fins of superbikes, which rely on wind generated by speed, BMW’s idea is to control aerodynamics actively, using artificially driven air.

This air can be redirected according to the need of the moment: backward during acceleration; forward during braking; upward to increase downforce; and even sideways, generating more pressure in corners.

A Compact And Versatile System
The system features an internal fan connected to a network of valves and ducts. This network allows for a precise distribution of airflow to improve the motorcycle’s performance in different situations.
The proposal is similar to traction control but based on real-time aerodynamics manipulation.
Although it may seem new, the idea has appeared on other occasions in the automotive world. A classic example is the Brabham BT46B from Formula 1, created by Gordon Murray in the 1970s.
The car used a large fan to create ground effect, winning its first race with Niki Lauda.
The system was withdrawn by the team’s own initiative to avoid an innovation war among manufacturers.

Another famous case is the Chaparral 2J, which also used auxiliary fans. Decades later, Murray himself revisited the concept in the development of the supercar T.50.
In 2018, Bosch attempted a similar approach using pressurized gas cartridges. However, the idea did not progress due to cost and complexity.
Now, BMW’s proposal seems more compact and, in theory, applicable to production motorcycles.
There is still no launch forecast, but the patent reveals that the manufacturer is open to new ways of dealing with grip.
Instead of solely relying on electronics or tires, the company bets on a solution that blows air as if the motorcycle were a drone.
