Could this young French speedster be one to keep an eye on in the future. Having smashed 40 knots at the age of just 14, Benoit Gaudiot plans to break 45 knots during the age of 15. Judging by our maths that means he will be pushing 220knots when he reaches 50... Ok perhaps not but he does having promising prospects as a speedster weighing in at 80 kilos already and six foot tall.
