Despite the fact that the team already held the world record, the developments did not come to an end. The team was (and still is) convinced that the limits of human capability have not been reached. In an attempt to go even faster, the VeloX IV was developed. The design was characterized by a promising but risky new aerodynamic shape: a ‘supercritical’ design, with mixed results. Still, Rik Houwers reached a speed of 132 km/h in the VeloX IV, securing the 4th win of the World Human Powered Speed Challenge in a row (and only 1.5 km h under the WR)! Additionaly, Christien Veelenturf achieved 111 km/h and ranked third in the women’s competition.
