World Solar Challenge: The Designs

The World Solar Challenge Challenger class is seeing some nice-looking solar cars this year. The majority of cars (19 so far, or 66% – teams 2, 3, 4, 5, 8, 9, 10, 13, 14, 16, 17, 18, 21, 23, 25, 26, 46, 77, and 82) are some form of the increasingly standard flat wing with asymmetrical cockpit. Solar Team Twente’s Red One (photo above by Jérôme Wassenaar) is a good example. This design has aerodynamic advantages, since the driver sits behind one of the front wheels (often, the asymmetry extends to propulsion as well, with only a single wheel being powered). Such asymmetrical cars were introduced at WSC 2013 by a few teams, including Nuon and Tokai.

However, some teams this year (9 so far, or 31% – teams 7, 15, 22, 27, 30, 32, 36, 47, and 51), have either retained or built some form of symmetrical wing, like Nagoya Institute of Technology’s Horizon Z (below).

Finally, Cambridge University’s Evolution (team 12, below) reflects a quite different, and rather promising, approach.
