Development — Underbody air guide elements
Development has commenced on a modular system of underbody components intended to refine airflow management on the BMW G8X platform. The focus is directed toward zones beneath the chassis that are subject to disruption from wheel-induced turbulence, where pressure instability can reduce aerodynamic consistency under extended load.
The system comprises three key elements: adjustable front tire spats, inboard-mounted air strakes positioned rearward of the front wheels, and adjustable rear tire spats. Together, these components serve to direct displaced airflow outward from the underfloor, supporting a more stable pressure distribution and improving the quality of downstream flow.
All elements are produced in glass fiber-reinforced nylon. The material offers a balance of mechanical stiffness, thermal resistance, and impact durability suitable for continuous exposure beneath the vehicle. Adjustable mounting geometry allows for adaptation to changes in alignment, ride height, and tire dimensions.
Installation is based on existing structural interfaces. Clearance has been evaluated to ensure compatibility with the factory underbody layout, and efforts have been made to avoid interference with service access or surrounding components.
Initial testing is underway to validate positioning and mounting behavior under load. A first image documenting the placement of the front strakes in situ will follow. Additional updates will be shared as development continues.
