Nuna2 managed to win the World Solar Challenge 2003 with an average speed of over 97 km / hour. This was a time of 31 hours and 5 minutes.
Nuna2 achieved a speed of 130 kilometers per hour during the race. The decisive factor for victory was the professional tracking team. This team was always able to determine the most advantageous speed by linking weather forecasts to expected energy revenues. The tire changes were also optimized, these only lasted 4 minutes, in contrast to the 12 minutes that other teams needed. Nuna2 weighed 250 kilograms, which is 30 kilos lighter than its predecessor. In addition, the aerodynamics had been brought to just under 0.9 CdA. Both resulted in a lower air and rolling resistance, allowing a speed of 145 kilometers to be achieved during a tour through Europe after the World Solar Challenge!
