Day 4 of the Sasol Solar Challenge saw the Dutch ahead of the Belgians again, by a mere 29 km. North West University (NWU) in their unique car (pictured) is still trying to catch up to Tshwane University of Technology (TUT). Coming up next is a “blind stage,” where the teams are not told in advance what the route will be.
