How Formula 1's Bargeboards Became So Complicated

How did bargeboards evolve from a curved panel to the complex carbon fibre structures we see today? Especially over the last few years, we've seen an explosion in complexity infront of the sidepods, but how did we get here? Jake Boxall-Legge takes a look at the first ever, ultra simplistic bargeboard in Formula 1, the many variations we've seen since and how they are so crucial to today's machines and their aerodynamics.
