# World Solar Challenge 1993

The 1993 World Solar Challenge was the third international solar-powered car race held over 3,000km from Darwin, Northern Territory to Adelaide, South Australia.
It was held from November 7, 1993 with the 'Dream' car from Honda Research and Development winning the event from 1990 winners Biel. Reports suggested Honda's vehicle cost AU$10 million, with Biel spending $3 million, with the total value of entrants estimated at $25 million.
Fifty-one entrants from 13 countries entered the race, which was completed at a record speed of 84.96 km/h, attributed to improvements in aerodynamics, motor efficiency and photovoltaic cells.
It was also supported by several mainstream automotive manufacturers, including Honda, Nissan, Toyota and Kia. Stuttgart University also operated a "semi-trailer sized" solar powered airship called Lotte to Adelaide as part of the event.

## Event sponsor

Japanese industrial gas producer Daido Hoxan was the naming sponsor of the event.

## Route

The World Solar Challenge runs across approximately 3,000km from Darwin, the capital of the Northern Territory, to Adelaide, the capital of South Australia.
