DSM Resins B.V. (Zwolle, The Netherlands) reported on Aug. 8 that the new solar car Nuna7 raced at the Zandvoort (The Netherlands) racing circuit as a final test before leaving for Australia to compete in the 2013 World Solar Challenge Oct. 6-13.
DSM says the Delft University of Technology team showed the capabilities of the composites-intensive Nuna7 in terms of speed, energy efficiency and handling. The team will compete in Australia for the seventh time. Since 2001 it has won the race four times and finished second twice. At this race’s edition, 48 teams will compete from 26 countries. Only cars powered 100 percent by solar energy are allowed to compete at the World Solar Challenge. The race covers a distance of 3,000 km/1,864 miles, starting in Darwin and finishing in Adelaide.
The new solar car has been completely redesigned following new race regulations. As innovation partner, DSM says it has supported the team with sustainable resins, the latest composites application technology and rapid prototyping. The car has few similarities to its predecessors, besides a very low drag resistance and light-weight construction. Nuna7 weighs only 150 kg/331 lb and can reach a top speed of 185 kmh/115 mph, purely using solar energy. The car is said to have a revolutionary asymmetric design; the driver is positioned in between two wheels on the far right side of the car.
