The iESC is the only 24 hours endurance race in the world for solar cars, which takes place every 2 (even) years at the former F1 track of Circuit Zolder in Belgium.

At the race track, the solar cars can show their full potential with low power consumption and fantastic aerodynamics over a full day.

During the Challenge, each team can make a maximum of 2 stops for charging. Since 2018, teams are allowed to participate with 2 solar cars.

The Bridgestone World Solar Challenge has welcomed the greatest minds from around the world to Australia to push the limits of technological innovation for over 30 years. #

As the world's toughest and most prestigious solar car event, the Bridgestone World Solar Challenge provides teams the opportunity to design and build a vehicle to operate along a 3,000 kilometre outback route from Darwin to Adelaide powered only by the energy of the sun.
