Thousandths of a second decide between victory and defeat in the bobsleigh. This makes the technology and aerodynamics of the material used phenomenally important in this rapid sport. Steering precision down to just millimetres and the mastering of tremendous physical forces are essential. Reigning world champion in the two-man bob, Francesco Friedrich, sees similarities between bobsleigh and motorsport. “When you have to steer so precisely in the channel, it is all intuitive. To a certain degree, it is the same when you are sat at the wheel of a BMW sports car.” The technological advances take place behind closed doors. When a bobsleigh races through the track at 140 km/h and up to 5g, this precision work is hardly recognisable to spectators.
