A new UK-designed entry into the World Solar Challenge has been testing in Australia.
The Cambridge University Eco Racing team will be pitted against 40 other teams from around the world in a harsh test of solar technology in the Austrailian Outback that covers over 1800 miles.
Their car uses space-grade solar cells and a special solar tracking board that ensures maximum sunlight penetration - meaning the CUER team's car should get up to 20 per cent more solar energy than traditional solar vehicles. An on-board electric motor that is up to 98 per cent efficient is used for power, while a regenerative braking system helps to recharge the batteries. The car has a top speed of 86.9mph.
The four-wheeled entry also incorporates design concepts from Formula One, such as the ultra-lightweight carbon composite chassis construction. A wheel-steering system also helps to minimise drag.
Drivers must endure four-hour stints inside the car's small cockpit, while outside temperatures of over 40C threaten to cause wildfires on the route - which almost caused last year's race to be cancelled.
