Defending Champs New Fin – Double Trouble for the Competition

Today saw the Bridgestone World Solar Challenge’s (BWSC) defending champion team, Innoptus Solar Team,
testing their latest ‘secret weapon’ at MKT airfield in Darwin, the lead up to their 2025 title defence.
This formidable, ‘top gun’ team arrived in Darwin earlier this month with a new solar car ‘Infinite Apollo’,
featuring one of the team’s boldest innovations yet: a dual-fin aerodynamic system.

Belgian Team Manager, Wout Rubbrecht said the new design is an evolution of the single rotating fin, used
so successfully to sail the crosswinds in the 2023 BWSC.

‘Infinite Apollo now has two asymmetrical fins behind the cockpit. Each has a unique profile and can be
deployed based on wind conditions to harness winds like a sailboat. With adjustable height, we gain even
more control — boosting aerodynamic efficiency and stability in the unpredictable Australian wind,’ Wout
said.

‘Our 11th solar car has unique technology and innovation. In addition to the dual fin, we have also developed
our most efficient silicon solar panel yet with next-generation cells significantly increasing efficiency.

‘We are all looking forward to contesting the title in Australia with the goal to becoming world champions
for the third time at the Bridgestone World Solar Challenge 2025. Innovation like the dual fin is so important
in a 3,000-kilometre endurance race where every second gained is precious and competition is strong. We
trust in our team spirit and our new car to bring the trophy home again,’ Wout said.

BWSC Event Ambassador, Chris Selwood AM, said he was looking forward to seeing the new fin in action.
“Innoptus is an exciting team that pushes innovation boundaries. As they celebrate the milestone of their
10th World Solar Challenge this year, I wish them every success on their 2025 BWSC adventure,’ Chris said.
