aero push

noun

auto racing

: an aerodynamic effect that causes a closely trailing car in a race to lose traction and maneuverability because of decreased downforce on its front wheels caused by the turbulence created by the leading car

The COT was supposed to eliminate the aero push via its adjustable front-end splitter and rear wing, both designed to better control the air flow between cars.—

Stock cars ruffle aerodynamics so much that cars in front of the pack handle much better than cars in the pack; the phenomenon is called aero push, which might as well be an epithet among drivers.—
