ANU Solar Racing Team begins outback testing for 2025 challenge

The ANU Solar Racing Team has commenced off-grid testing in Coober Pedy, South Australia, ahead of the 2025 Bridgestone World Solar Challenge, with support from Uniden Australia.

Comprising more than 50 students from diverse academic backgrounds at the Australian National University, the team is currently conducting rigorous preparation of its fourth-generation solar vehicle, named Solar Car 4 or 'Monty', as they approach the start of the 3,022km race from Darwin to Adelaide.

The vehicle, which features a carbon fibre asymmetric catamaran chassis and is powered by high-efficiency Heterojunction solar cells, has been constructed to compete in the Challenger Class of the event. Monty operates on three wheels and can reach speeds up to 130km/h.

The Bridgestone World Solar Challenge is recognised as one of the most demanding endurance races, covering remote and challenging terrain across the heart of Australia. Robust preparations are considered essential for participants, given the isolation and operational requirements of such environments.

The team is currently engaged in intensive testing in Coober Pedy, focusing on both the vehicle's technical performance and the operational reliability of associated support equipment. Following this phase, the team is expected to travel to Darwin to begin on-site preparations for the official start of the race.

Strategic partnership

This year, the ANU Solar Racing Team has formalised a partnership with Uniden Australia, which has supplied UHF radios and dash cams for the duration of the testing and the race itself. The devices are intended to ensure secure communications and improve team coordination across the long distances anticipated during the challenge.

Brad Hales, Head of Marketing Oceania at Uniden, commented on the company's involvement with the project.

"We're incredibly proud to support the ANU Solar Racing Team in their mission to drive innovation and sustainability. This partnership is a perfect alignment of Uniden's commitment to cutting-edge technology and support for the next generation of STEM talent."

According to the team, the presence of reliable communications equipment is a critical component of their operational planning, especially during testing in remote areas where access to conventional infrastructure is limited.

Cameron Wallace, Business Lead for the ANU Solar Racing Team, highlighted the importance of this facet of their preparation.

"Testing in remote Australia means reliable communication is non-negotiable. Uniden's high-performance equipment gives us the confidence to focus on what matters: refining the car and preparing our team for race day."

Technology and preparation

Solar Car 4, the latest in a series of vehicles developed by the team, is the product of ongoing research and collaboration among students in engineering, science, business, and computer science. Its design prioritises energy efficiency and durability to withstand the physical and environmental challenges of long-distance solar racing.

The use of a carbon fibre chassis and advanced solar cells reflects current trends in sustainable engineering, aiming to maximise distance travelled on a single solar charge while meeting stringent safety and performance criteria set by the race organisers.

Given the length and isolation of the route between Darwin and Adelaide, off-grid communication and real-time monitoring through dash cams are expected to play a pivotal role in event logistics, safety, and team coordination.

The testing currently underway in Coober Pedy involves simulated race scenarios, stress analysis of the vehicle, and extensive trials of support equipment under extreme conditions. Outcomes of this phase will inform final adjustments to the vehicle and strategic approaches for the official race.

The ANU Solar Racing Team will continue its preparation in the weeks leading up to the event's official start, with a focus on ensuring that both the technical and operational aspects of its campaign meet the rigorous standards of the Bridgestone World Solar Challenge.
