History

The Nuon Solar Team has won the World Solar Challenge four times (in a row) with Nuna
Nuna 1
Nuna 1 was a car powered by solar-power, developed by students from the Delft University of Technology.The first Nuna Team was founded in 2000 by Ramon Martinez and Tim de Lange. The project was sponsored by Nuon. Thanks to this financial help the team was able to finish their first car: Nuna 1...

In July 2010. Nuon Solar Team and Nuna5 visited Japan.They visited several University and City Office.
In August 2010, Nuna 5 ran third, in the Suzuka Dream Cup in Japan.

Design and production of Nuna 5

The Nuon Solar Team began designing Nuna5 on a fulltime basis in September 2008. After two series of wind tunnel tests at the Low Turbulence Tunnel laboratory of Delft University of technology in December and January, the aerodynamic design was finished late January 2009.

The team began building the car in February 2009. The body was built from carbon fiber

The car was involved in a serious crash on October 5, 2009 while on a practice drive in Australia. A tire burst while the car was traveling at 110 km/h [68 mph], causing the car to run off the road sustaining severe damage.

s have an estimated efficiency of 34% and are normally used on solar panels in space.
By regulations it is allowed to carry 6 square meters of solar cells. Due to the type of solar cells on Nuna 5, it will compete in the Challenge Class of the World Solar Challenge.

World Solar Challenge 2009 - New regulations

The 2009 regulations are comparable to those from 2007 (the year Nuna 4 raced). The major change was the diminished battery weight, changing from 30 kg in 2007 to 25 kg.

Other changes required cars not be allowed to race on, previously used, slicks (smooth tires), requiring profiled (treaded or grooved) tires. Also, the driver was required to sit more upright with a seating angle of, at most, 27 degrees.
