Silvretta · Darwin to Adelaide · 24–31 August 2025

Silvretta, our second car, raced across Australia in the southern winter: cold nights, fierce crosswinds and storm cells along the Stuart Highway, where the crew shielded the car to protect its bodywork and solar array, and torrential rain on the last day.

Silvretta reached Adelaide after 44 hours and 42 minutes of racing, 11th in the Challenger class and one of 14 of the 22 starters to finish.

How the race works

The Bridgestone World Solar Challenge runs every two years across Australia: 3,021 km from Darwin to Adelaide along the Stuart Highway, on public roads.

We race in the Challenger class: single-seat cars that run on the sun alone, with a battery that may only be charged by their own solar array. The fastest time to Adelaide wins.

The cars may drive from 8:00 to 17:00. At five they stop wherever they are, and the team camps beside the road. At the control stops along the way every car waits 30 minutes.
