The very essence of the ‘form follows function’ design philosophy can be found in motor racing. Here, the only thing that counts is what makes a car fast. As we all know, beauty alone doesn’t win races. And yet, some racing cars are more iconic than others simply because of their liveries. This will be wonderfully evident on 15 and 16 August at the London E-Prix, when Porsche takes to the track with a historic livery – for the second time this season.
