Coober Pedy — The Bridgestone World Solar Challenge hit the opal capital this morning with a razor-thin gap between the front-runners. Brunel Solar Team (Netherlands) reached the Coober Pedy checkpoint first at 8:30am, chased by compatriots Solar Team Twente at 8:36am. Innoptus Solar Team (Belgium) arrived moments later at 8:36am, third across the line at the stop but sitting fifth overall on provisional standings. In contrast, Team Sonnenwagen Aachen (Germany) checked in at 9:54am yet holds third overall on cumulative time.

The split times underline how tight—and tactical—this year’s 3,000-km Darwin-to-Adelaide epic has become. Overall order can differ from checkpoint arrival times because it’s based on total elapsed time (plus any penalties), not just who rolls in first at a control stop.

Coober Pedy is one of the official control stops on the route that shadows the Stuart Highway south before swinging to Adelaide’s finish. From here, teams push on to Glendambo and Port Augusta before targeting Victoria Square / Tarntanyangga in the CBD. Control-stop windows published by the organisers show Coober Pedy operating through Thursday 28 Aug, 1:00pm, with Glendambo and Port Augusta following later that day and into Friday.

The World Solar Challenge is a biennial test of student-built, ultra-efficient machines, famous for demanding energy management, strategy and reliability across Australia’s interior. The course spans over 3,000 km from Darwin to Adelaide, largely down the Stuart Highway.

With minutes between the leaders and weather always a factor, the run to Adelaide remains finely poised. Spectators can keep tabs on positions and speeds via the event’s live tracker, which refreshes regularly as teams head south.
