Founded in 1987, this is the 20 th anniversary of the world’s premier solar race. The 2007 route heads south from Darwin all the 3021km to Adelaide, cutting right across the Australian continent. In the last race, cars travelled at speeds up to 130km/hr and support teams had a hard time keeping up – this year, rules have been altered to slow the vehicles down, with the added benefit of making them closer to practical vehicles.
