The Sunswift 7 solar powered car weighs just 500kg, while an average car weighs between 1,500 and 2,000kg. It also boasts incredibly low rolling resistance due to its shape. A team at UNSW Sydney designed and built this solar powered car which completed 240 laps of a special test circuit, equal to driving from Sydney to Melbourne, plus 100km. It covered the distance in just 11 hours and 52 minutes, setting a new world record time for an electric vehicle on a single charge and reaching an average speed of 85kph. The car stopped to change driver every few hours, as well as once for a puncture and once for a battery fault. However, the Sunswift 7 solar powered car is a ‘performance car’ and not meant for the roads. It was designed without features such as airbags and AC, which add weight.
