The Sasol Solar Challenge is a biennial competition. Teams from across the world design and build solar-powered vehicles to drive across South Africa in an eight-day event. The 2020 event will take place from 11-19 September 2020.

Local and international solar-powered cars travel as far as they can on various roads and loops between Pretoria and Cape Town. 

In 2018, the teams traveled distances between 2 500 and 5 000 km, and the same can be expected for 2020.
