FROM SPOILERS TO GROUND EFFECT: A TIMELINE OF AERODYNAMIC BREAKTHROUGHS IN RACING   What do a 1970s Lotus, a Le Mans prototype, and a modern NASCAR have in common? They’ve all been shaped aerodynamically by the wind.

For decades, motorsport engineers built cars with one goal in mind: to outrun the competition. That meant more power, less weight… and not much else. In today’s racing world, every technical leap calls for a rethink of pieces: auto, movable wings, smart diffusers... But back then, aerodynamics was a vague, almost annoying concept. And yet, the air was always there.
