Stellantis Wind Tunnel Moving Ground Plane Technology

Stellantis unveiled its innovative Moving Ground Plane (MGP) technology – a $29.5 million investment – at the company’s research and technical center in Auburn Hills, Michigan.

The upgraded wind tunnel will be able to measure and reduce airflow resistance from wheels and tires, which can account for up to 10% of total real-world aerodynamic drag.

Optimizing aerodynamic efficiency is crucial in the effort to extend the driving range of electrified vehicles on a single charge. This enhancement directly contributes to improved efficiency, benefiting customers with longer EV ranges and potentially reducing battery sizes, which in turn could lead to cost and weight savings.

The upgrade to the company’s innovative aero-acoustic wind tunnel simulates real-world travel while allowing test vehicles to remain static. Belts suspended by cushions of air enable wheel movement at all four corners, while a fifth belt runs longitudinally beneath the vehicle, mimicking on-road travel conditions.

This realistic simulation allows for more precise testing and aerodynamic improvements.
