BMW aerodynamics helps Brit swimmer Rebecca Adlington

With Olympic mania well and truly underway, BMW has revealed that double champion swimmer Rebecca Adlington has been using the brand's expertise in aerodynamics to analyse her underwater performance ahead of the games.

Along with the London 2012 automotive partner and sports scientist Professor Grey Whyte, Rebecca's hydrodynamic performance across her dive and turns has been studied, as well as when she was swimming beneath and on the surface.
